In this manual an attempt has been made to place before the reader, as briefly and completely as possible, the prin- ciples of design in textile fabrics in its broadest sense, and to deal with the subject in such a manner as to com- bine with the question of decoration that of the proper structure of the cloth. The practice of paying little or no attention to the proper structure of the fabric, and its suitability for the purposes to which it is to be applied in the ar- rangement of designs, is unfortunately far too common, and is the cause of a considerable waste of labour and expense in our manufacturing concerns. This may, perhaps, be to some extent due to the method of training those who are to be the designers, and also, to an even greater extent, to the fact that there has hitherto been no systematic treatment of the question. Most men engaged in the manufacture of textile fabrics have confined their attention to one branch, or to one class of goods, and have become proficient from practice only in that class. Their success has been entirely dependent upon the amount of attention they have paid to the particular class of fabrics they were engaged in manufacturing, or to the accuracy of their observations, and not to any — or, at the most, only to a slight — degree upon any systematic method or basis for their work. In the textile trades, as in every other, the vi DESIGN IN TEXTILE FABRICS. "nile of thumb," or guess-work, must rapidly disappear, and be replaced by system. Fabrics must be made, as other articles are, with a proper regard to ornament, utility, and economy; the designer must consider both the end and the means, and nothing but this will secure success to him. The rapid disappearance of the old apprentice system, the growth of large establishments, and the consequent subdivision of labour, accompanied by the ever-increasing demand for fabrics of a more artistic character to be applied to useful purposes, make it imperative upon the would-be designer or manufacturer to understand more fully than he has done in the past the principles upon which fabrics should be constructed, so as to fulfil all the necessary conditions. He must work on sound principles and leave nothing to chance. The reader must not expect to go through this work in a hurried manner, or to thoroughly grasp all the details of the subject without further efibrt. Within the compass of this volume it is, of course, impossible to enter into all the particulars which would make the student at once perfectly conversant with the whole ; but an efibrt has been made to lay down the leading principles clearly and completely, and to guide the student generally, rather than to enter too closely into minor details, which can only be sufiiciently mastered by actual practice in the mill or workshop.

The Objects to be kept in View in designing Textile Fabrics. — The first objects we must set before us in designing textile fabrics are the uses to which they are to be applied, and the purposes they are intended to serve. Exactly in the same manner, if we are designing a bridge, a house, a mill, or a machine, our first concern must be to secure all the conditions of strength, con- venience of arrangement, and other requisites, which will make it most suitable for the purposes to which ifc will be put. This having been done, we may then proceed to ornament the structure as we please, always taking care that the ornamentation does not in any way detract from the conditions of strength and general utility which have been our first and foremost aim. It thus follows that, in speaking of designing textile fabrics, we do not necessarily mean the application of art principles to their decoration, but we use the phrase in a more compre- hensive sense, not only in reference to the decoration or ornamentation of the fabric, but also to its structure. If that is so, we must have what is commonly termed a theoretical basis upon which to build our fabric, and it may be as well to inquire, before going further — What is this theoretical basis 1 or 2. What is the theory of the structure of fabrics ? — theory may be described as a supposition with B 2 DESIGN IN TEXTILE FABRICS. [Cbap. I, regard to cause and effect — or the connection and sequence of phenomena — which embraces all the circumstances known to attend their occurrence. A theory is tested by trial and observation. It must be founded upon actual knowledge of things — of the end to be attained, ' and the means which have been employed, not only by ourselves but by others, to attain the object at which we are aiming, or a similar object. Upon this basis, then, we may at once proceed to examine into the theory of the manufacture of cloth, or " Design in Textile Fabrics." Before we can enter into the question of the structure of fabrics, or deal with the materials from which they are made, we must deter- mine what are the purposes they are intended to serve, and the qualities or properties they must possess to ensure those purposes being served in the best possible manner. It may, in the first place, be said that one of the chief uses of textile fabrics is as a covering for the body, to keep it warm, or to protect it from the incle- mency of the weather ; or it may be that the covering is merely ornamental, and need not be of such close texture as that which the needs just referred to demand. Again, whether the covering be of . the purely useful or of the purely ornamental character, yet, in all probability, in each case it will have to fulfil one condition of usefulness — namely, wear. This means that its structure must be such as will enable it to bear some strain, and in many cases also to resist a considerable amount of friction without damage. In addition to the fabrics of a purely useful or purely ornamental character, we may in many cases be called upon to produce fabrics where both qualities are requisite. As the artistic taste of the people improves, they are not contented with the purely useful ; articles of utility must also be made more or less beautiful. We must ornament wherever we can, but in introducing the ornament we must be careful that we do not do it at the cost of utility. "We may, then, say that in these considerations of Chap. I.] WARP AND WEFT. 3 utility or ornament we have the groundwork or basis of our theory. We have the knowledge of what we require, but that is only the first step. Before our theory can be complete we must consider how these fabrics are to be constructed, the materials from which they are to be made, and also, to some extent, the mechanical operations involved in their formation ; and, being guided by a knowledge of what others have done before us, we must, as far as we can, determine the best and most economical methods of obtaining given results. Textile fabrics may be generally described as a com- bination of filaments or threads, interlaced with each other in such a manner as to form a texture ; and it is for us to ascertain what is the best method of interlacing those threads, so as to produce the fabric most adapted to our requirements. In all cases where utility is to be the first considera- tion, the warp and weft threads which form the fabric must be so interlaced as to produce all the firmness possible, not only so as to be able to bear the greatest amount of strain, but also to be able to resist i'riction. In many instances we must also combine with these qualities bulk, or thickness of fabric ; consequently, our fabric must be constructed so as to allow of the requisite ^ amount of material being in- b troduced into it. 6 Before going any further » into the subject, we will see * how fabrics are constructed, * and what is the meaning of * warp and weft." In Eig. 1 ^ we have a plan of what is Pig ^ known as a plain cloth. It will be seen that there are two sets of threads, which cross each other at right angles, and interweave alter- nately. The threads marked a, or the longitudinal threads— or those running in the direction of the length 4 DESIGN IN TEXTILE FABRICS. [Chap. I. of the piece, and which are usually shown on paper in a vertical position, are what are termed the warp threads, and the transverse threads, 6, are termed the weft threads. In all woven fabrics we have these two sets of threads to deal with^ and the relation which one bears to the other, as well as the order of interweaving for the purpose of forming patterns, constitute the design of the fabric. In the plain cloth plan in Fig. 1, it will be seen that, although we produce a very firm texture by the manner in which the two sets of threads interweave, yet we cannot possibly produce a very close texture. Certainly the fabric will be strong, each thread supporting the other to the utmost, yet it cannot be made sufficiently compact, either to produce a heavy fabric or a fabric which will retain heat, or keep the body warm to the fullest extent. By the very manner in which the threads intersect each other, they are prevented from lying per- fectly close together ; consequently, the fabric must be, in a greater or less degree, perforated. 3. The Effect of the Yarn upon the Fabric— The perforations in a plain cloth will vary greatly under certain conditions : for instance, the thicker the threads from which the fabrics are made, the larger will be the perforations, and the thinner the threads, the smaller the perforations. Of course, in such cases the perforations will bear exactly the same ratio to the diameter of the thread if the relation of warp to weft be the same, but cloth made from fine yarns will possess the useful properties in a much greater degree in proportion to its weight than that made from thick threads. Other considerations will also affect the usefulness of the fabric. If we desire to produce a fabric of close texture — one which will have the perforations reduced to the smallest possible dimen- sions and retain the warmth of the body in the highest extent — we must use a yarn in which the fibres of which it is composed are laid as loosely together as possible We can then, in the mechanical operations of weaving, Chap. I.] TWIST OF THE YARN. 5 bring those threads closely together, and the looseness of the fibres will permit of their spreading out, and so of reducing the interstices to the lowest point. On the other hand, if the threads are twisted very hard — that is, if the threads are made solid and compact — ■ they will resist compression in the operation of weaving, and, the fibres being held firmly together in the thread, there is nothing left to spread out and cover the inter- stices ; consequently, we shall have an open fabric, but the fibres being firmly interlocked in the thread, we shall have a fabric which will bear more strain, and will ofier also more resistance to friction, than in the other case. We must, therefore, obtain one quality in this fabric at the cost of some other. 4.— The Effect of the Twist of the Yarn.— Another matter which materially afiects the closeness of texture in a plain cloth is the direction of the twist of the weft in relation to that of the warp. On reference to Fig. 1 it will be seen that the two sets of threads when placed together in the fabric have the twist running in the same direction ; that being so, the fibres — or, if we may so term them, the strands — of the two sets of threads will 6 become embedded into each b other, and so make a close & and compact fabric. If, on ^ the other hand, the twist of ^ the weft be contrary to that * of the warp when the two are placed together, as shown in ' ^ ^ ^ a a a a a a a Fig. 2, the threads cannot Fig. 2. become so intimately con- nected, and, consequently, the fabric cannot be so close and free from perforations. To give an illiastration on a large scale. If we take two thick cords or ropes, and lay them together at right angles to each other, with the twist of both in the same direction, we shall find that the thick strands of one 6 DESIQN IN TEXTILE FABRICS. [Chap. I. rope will fall into the hollows between the strands of the other, and so the two will occupy the smallest possible space ; but if the strands are in opposite direc- tions, instead of their falling between each other, and one strand filling the hollow in the other, their ridges will come together, and there will be an opening equal to the hollows between the strands of both ropes. We have, therefore, increased openness in the struc- ture of the fabric without a corresponding gain in any direction. 5. Relations of Warp and Weft, and their Effect upon the Fabric. — Up to this point we have been dealing only with what may be called a true plain fabric, or a fabric in which the weft and warp are equal, or nearly so, in their diameters and in the number of ends per inch each way; but we may produce fabrics in which the relations of weft to warp are quite altered, and we may do this for two purposes — either for obtaining increased strength, warmth, and weight, or for ornamentation. Suppose we take the class of fabrics commonly known as poplins, and which present a corded or ribbed appear- ance, the ribs running across the fabric in the direction of the weft ; in such fabrics there is a great preponder- ance of 'warp over weft, more especially as regards the number of threads per incL But for the production of fabrics of the best type the warp threads are much thinner than those of the weft. In fact, although the interweaving of weft with warp is precisely the same as in the plain cloths with which we have been dealing, the alteration in the relative quantities and thickness of weft and warp completely changes the texture and appearance of the fabric. A plain cloth, in which warp, and weft are equal, will present an appearance of waviness in both warp and weft on the fabric being dissected ; but a fabric in which the warp threads predominate largely over the weft, so far as ends per inch go, and in which, consequently, the warp threads are proportionately thimier, would present the weft as a straight line, and Chap. I.] RELATIONS OP WARP AND WEFT. 7 Fig. 3. the warp bending round it, A plan of this fabric is shown in Fig. 3, and a section in Fig. 4. In the plan it will be seen that the weft threads are much thicker than the warp threads, and also that the latter are placed closely to- gether. In some fabrics of this type these are placed so closely that they are actually compressed, and made to occupy a space less than their true dia- meter. It will also be seen that the weft threads are some dis- tance apart. It only requires a careful examination of the structure of the fabric to ascertain the cause of this, as also its effect upon the appearance, as well as upon the usefulness of the cloth. The warp threads are placed close together, and cross between each weft thread, or pick, as it is tech- nically termed. The warp is also much thinner Fig. 4. than the weft ; as a consequence, no matter how much tension may be put upon the warp, either in the process of weaving or after the fabric is formed, it cannot bend the weft out of its straight line, simply because the intervals of space between the warp threads are so small, as compared with the thickness of the weft, that the weft cannot be bent into them either from above or below ; or, in other words, the close- ness of the warp threads forms a continuous bed upon which the weft is laid.. Then, with regard to the distance apart of the weft threads, or picks, the warp crossing between them prevents them from coming close together ; each pick being separated from the other in this manner produces the ribbed-like eifect peculiar to this class of fabric. It will be evident from the structure of the fabric, the closeness 8 DESIGN IN TEXTILE FABRICS. [Chap. 1. of the warp threads, and the strength of the weft that this class of cloth is well calculated both to resist wear and retain warmth, and there is, probably, no kind of fabric which, for the weight of material employed, can compare with it in these respects. Another class of fabric of a very similar character is largely employed for decorative purposes, and to some extent also for articles of dress— namely, the cloth com- monly known as "repp." Its structure is dif. ferent from that of either of the two plain cloths of which we have been speaking, though possessing one of the chief characteristics of the poplin, or gros-grain, type, inasmuch as the warp is made to bend round the weft, and the weft is laid in perfectly straight lines. In Fig. 5 we have a section of what is consi- dered the best type of this class. Here it will be seen that in both the warp and the weft there is a thick and a thin thread alternately, and in the operation of weaving the thin thread in the warp is held very tightly, while the thick thread is held very loosely. Again, the thin weft is always between the warp threads on the same side of Fig. 5. the thin thread, and the thick weft passes always on the contrary side of the same thread; the result is that the thick warp— which usually consists of several threads put together— m consequence of the slight tension upon it, is made to bend round the weft threads, and the thin warp is held quite or nearly straight, thus producing the clearly- defined rib, very prominent on that side of the fabric where the thick weft is, and less so on the other side. Again, another class of plain fabric is obtained by a reversal of the conditions which produce the poplin that is, the warp threads are thick and the weft thin. The warp is held in straight lines, and the weft made to bend round it. The plan shown in Fig. 3 may be taken Cliap.I.] RELATIONS OF WARP AND WEFT. 9 as a plan of tliis class of cloth, as well as the plan of a poplin cloth, only that the thick straight threads must be taken as warp, and the thin bent threads as weft The section Fig. 4 would also be a section of this cloth, but would be a transverse section, the circles showing the end of the warp threads and the bent threads being the weft. This class, commonly known as cords, is usually made with two or more warp threads run together to produce the requisite bulk, instead of usmg one thick thread. ^ , r i • In the production of the four classes of plam fabrics mentioned, great care should be exercised m proportioning the warp to the weft, but more espe- cially with reference to the poplin and cord. In what we have spoken of as the true plain cloth we have assumed that warp and weft are equal m quantity, and in that case both warp and weft would be slightly bent out of the straight line ; each would exert an equal power over the other. That being so, if faction be applied to the cloth, each set of threads would hold the other firmly in its place, and no matter whether the friction be applied in the direction of the warp or weft, the result would be the same— each would possess the same power of resistance. In the other classes it would not be so. If we take the poplin type, where we have the weft laid straight and the warp bent round it any friction in the direction of the warp threads could have Httle or no effect ; but friction in the direction ot the weft would have the effect of displacing the warp, because there is nothing to keep them m place except their pressure one against another ; they are bent round a straight body more or less smooth, and have no support except their own pressure. Thus, unless they are sufficiently close together to give each other sufficient support, the cloth cannot be serviceable as an article ot dress, or for any other purpose where it will have to resist friction. The same remark will apply also to the " repp " and " cord " classes, but in the latter the dis- 10 DESIGN IN TEXTILE FABRICS. [Chap. I. placement will be in the weft threads by friction in the direction of the warp. In all four classes of plain cloth we could only vary the weight of cloth by altering the size of thread ; and our means of ornamentation are also limited. We can only alter the size of cord or rib by the use of different sizes of threads ; but we can ornament the fabric by the introduction of colour, and that colour we may use in the warp only, in the weft alone, or in both warp and weft. So far as the use of colour goes in ornamenting plain cloths, we have a wide field ; but that is a subject we must consider in another chapter. We must first deal with the structure of fabrics, and their ornamentation by the variation in the interweaving of the threads which compose the fabric. 6. Twilled Fabrics.— We must now discuss the structure of other than plain fabrics, and ascertain what is the use or value of other methods or systems of con- structing cloths. The class of fabrics which comes nearest to plain cloth is that known as twills or twilled fabrics ; and in their production we may have two objects in view first increase of bulk or thickness of fabric; and second' ornamentation. The first and chief difference between the structure of this class' of cloth and plain cloth is that in the latter the warp and weft interweave alternately whereas in twilled fabrics they interweave at such intervals as may be required for the formation of the pattern. Again, what is termed the complete pattern in plain cloth is represented by two ends of warp and two picks of weft, while in twilled cloth a greater number of ends and picks are required to complete the pattern; or, in other words, in all plain cloths, every alternate end is a repetition ; the same holds of the picks, but in twilled cloths the repetition will occur at lono^er intervals. Fig. 6 is the plan of a twill of a very comnTon order, and one regularly in use in fabrics made from all kinds of materials. Chap. I.] TWILLED FABRICS. 11 In this it will be seen that each warp thread passes alternately over and under two weft threads or picks, and in like manner each weft thread passes alternately under and over two warp threads. But each end does not pass under and over the same two picks, nor does each pick pass under or over the same two ends, nor are they alternate in their action, as are the ends and picks of plain cloth; but they change in regular consecutive order ; that is, if the first end passes over numbers one and two picks, the second end passes over numbers two and three picks, and so on, each end advancing one pick before it rises to the surface, or passes to the back, and each pick advancing one end in the same manner. This order of changing of the ends and picks will have the effect of producing a distinct pattern upon the fabric, a species of cord running in a diagonal direction across it. But another matter of much more importance than the mere pattern is the fact that this order of working permits us to introduce more material into the fabric, and so make it more bulky and closer in its struc- ture. The reason for this is to be found in the simple fact that the weft and warp interweaving only at in- tervals of two ends or picks permit the two threads both of warp and weft to lie closely together, and consequently to allow of a gi^eater number per inch to be introduced into the fabric than can be done in plain cloths. True, as we have shown, we may make plain cloths in which the warp threads lie perfectly close together, and others in which the weft threads lie perfectly close together ; but in the one case the weft threads are a con- siderable distance apart, and in the other the warp threads 12 DESIGN IN TEXTILE FABRICS. [Chap. I. are a considerable distance apart, whereas in the twill cloth the weft and warp both lie equally close together, so that we obtain the requisite closeness of texture in both directions, and a corresponding increase in the bulk of the fabric. Along with this closeness of texture and increased weight or bulk, we also obtain another advantage over the plain cloth, namely, that by the order of interweaving the warp bends round the weft, and the weft round the warp in an equal degree, exactly as m the first order of plain cloth. So that if the number of threads per inch each way is properly pro- portioned to their diameters, and to the order of inter- weaving, the fabric wHl possess the power to resist friction, not merely in the same degree as the plain cloth of the first order, but in a greater degree propor- tionate to the increased quantity of material it contains 7.— Alteration of Twill to increase Bulk.— We also possess the power of increasing the bulk in a great degree by altering the twill so as to inter- weave the two sets of threads at greater intervals, and just as we increase the intervals we increase the number of threads which may be contained in a given space Of course along with this a limit of increased usefulness will be reached. We say that we increase the powers of resisting friction by the increased material employed m the construction of the fabric, but if our intervals of interweaving are too great, the two sets of threads will to some extent lose their power of support- ing each other; we shall have too great a length of loose yarn presented on the surface. This yarn beincr composed of fibres, each individual fibre is presented for a considerable portion of its length to the wearinc. surface ; and if friction be applied, it may be too readily drawn away from its fellows, and so by degrees the thread and ultimately the fabric, becomes weakened. Again^ no doubt the looseness of the interweaving will reduce the power of the fabric to bear a strain ; although a loosely interwoven cloth— if the quantity of yarn be properly Chnp. I.] SATIN FABRICS. 13 proportioned to the order of interweaving— will still be the stronger so far as tensile strength is concerned, than one more closely interwoven, yet it will not be so strong in proportion to the quantity of material oi which it is composed ; and if the number of threads m a +Pr nnd nrld BDBBOGBDDBBnBBanBnnBnBBDBBaaBa cnaracter, ana aaa BBQBHDDBnaBBDBBDDBanBBnBBDDBnD hpQii+v+n ^■l^pf^^'hrl■f □□BmBBDBBDDBnnBHDBBDDBDnBBnBB Deauty to tneraoric □BaDBBnBBmBODBBDBBDBDDBnnBBnB wiflimit in anv BaaBBnBBDDBnDBBaBBmBBnnBDDBBg witnout m any □□^■□■■□□■□□BBaBBnnBnBBDaBaaBa flpo-rPP nflTpf+ina itq □BBDBBDDBDnBBDBBanBDBDBBDDBaDa degree anectmg its BBgBBDDBnDBBaBBnrjBDDBBDBBnnBaa c+rnr-tnrp nr USP- BaBBaDBDDBBDBBnDBnDBDBBDBBDDBg structuie ui ube □BBnDBDDBBnBBnnBaDBBaaBBDBBaaB fnlnpsn'ssss^ ^^isss^' ^s:^ are woven together are made from the same material, it requires the greatest possible care to insure the quality ot the two being the same in texture as well as in the material from which they are made. The pattern of each cloth must be so arranged as to secure this, other- wise the fabrics will not be perfect. We will begin, for example, with an illustration of the simplest kind, and combine two patterns which are probably more known and used than any other— that is a four-end twill and a plain cloth, as in Figs. 70 and 71 buppose we are weaving two cloths together, one of which IS plain and the other the twill given here, and that the threads per inch both in warp and weft, and the thickness of these threads, are □□□■□□□b the same in both. The two could not be equal in texture. One would be much firmer than the other; they could not both be equally perfect in structure. If the quantity ""^r'^" or_ thickness of the material be arranged to ' suit one of the patterns and to make it a perfect fabric It could not make the other equally perfect. Perhaps a medium might be found— the plain cloth made heavier and firmer than it should be, and the twill lighter and looser, so that neither should be so far removed from a true and perfect structure as to be so imperfect as to be objection- Chap, v.] RELATIONS OF QUALITY AND PATTERN. 93 able ; and, at the same time, tlie two might be so intimately bound together that the plain or stronger fabric would support, and to some extent improve, the strength and quality of the twill cloth. Still, with all these pre- cautions, there would be danger of the fabric being imperfect. In the process of weaving the plain cbth would work very tight and firm, and would require a greater length of warp to make a given length of cloth. Again, not only will there be more shrinkage in the warp (which may be overcome by letting the two warps come from difi"erent warp-beams), but there will be more shrinkage in the weft, because of its having to bend more round the warp threads in a plain cloth than in a twill. In some cases, perhaps, this may be advantageous, because if the two cloths are sufficiently bound together it will in its shrinkage carry the twill cloth with it, and so give greater roundness to the twill. On the other hand, if the fabric has to undergo a process of finishing, which will cause shrinkage, the twill cloth, because of the very looseness of the threads, will be liable to shrink more _m the finishing than the plain one, and so counteract its influence. But in- fabrics of this description the two must be bound together very closely. It is difficult to estimate the exact amount of shrinkage which is likely to take place relatively in the two cloths, and more especially if the process of finishing be a severe one, or if the material be of a nature which will assist the shrinkage, as, for instance, in woollen cloths which are milled. If, in sueii cases, the two cloths are too loosely bound together, or the points of binding are too far apart, that which shrinks most, even if it be only in a slight degree, will cause the other one to form bubbles, or "cockle," and so give a most unsatisfactory appearance to the whole. It is even more difficult to deal with fabrics of this class if we attempt to figure with them in the same manner as when the two cloths are equal in quality and texture, because usually in figured double cloths there 94 DESIGN IN TEXTILE FABRICS. [Chap. V. IS no binding introduced, except where the two cloths intersect each other. Consequently, if one should shrink more than the other, the " cockles " or bubbles would exactly correspond with the figure. There are double cloths where an efiect similar to this is aimed at, but in such we must adopt means which will ensure the even- ness and regularity of the embossed character which it wdl present ; we must not trust to chance, or the possi- bility of the effect being produced by one shrinking more than another. It may be all very well to rely upon it to some extent, but we must not do so too much, other- wise we shall probably be often disappointed. It will readily be seen that the combination of two cloths of the same quality, so far as the number of threads per inch and thickness of these threads is con- cerned, but of different patterns, is not a desirable thing to practise, unless for some specific purpose; and even when resorted to great care and skill must be exercised to secure the proper result. Sometimes, per- haps, it may be necessary, but it is well to avoid it as far as possible, and where it must be employed, let the conditions be examined with the greatest care, otherwise disappointment will be sure to follow. 68. Cloths of the same Pattern, but dilferent in Quality.— What has been said of cloths which are of the same quality but differ in pattern will apply practically to cloths which are of the same pattern but differ in quality. For instance : if we make two cloths together in the same loom, both of the same pattern, and both having the same number of threads per inch, but the threads of one cloth of a different thickness from those of the other, the two cannot possibly work well together, or assimilate ; and it is an imperative condition in nearly all double cloths that the two must assimilate and combine to form the same fabric ; but if one be very fine, and the other be very coarse, this is scarcely possible. It may be said, if we combine two cloths of the same pattern, each composed of threads of different Chap, v.] RELATIONS OF QUALITY AND PATTERN. 95 thicknesses, we may vary the number of threads so as to compensate for the difference in thickness. That is perfectly true; but there must be some harmony between the relative number of threads in each cloth. Suppose, for example, one had, say, sixty threads per inch, whilst the other had eighty-five, there would be a difficulty in weaving. In the first place, they could not be arranged satisfactorily in the reed, nor could the weaver arrange the succession of the picks in any definite order without an immense amount of labour. The points of binding the two together would be ever varying in relation to the pattern, and altogether there would be endless confusion in the work. To weave double cloths satisfactorily it is imperative that there must be reg-ular order of succession of the threads of both warp and weft; that is, they must be alternate, or two of one cloth to one of the other, or some such order. Then it follows that if the patterns be equal, and the threads are alternate, the diameters of the threads must be equal. If the patterns be equal, and the order of succession or proportion of threads m one cloth be two to one, then the diameter of the threads must bear the same relation to each other ; and what- ever the proportion of threads in one cloth be to the threads of the other, their diameters must bear the same relation. Fabrics of this description are often made, but unfortunately the true ratio of the threads per inch and their diameter are not always considered, and even if they are, they are in many cases considered upon a false basis, the designer proceeding upon the assumption that the diameters of threads vary in the direct ratio of their weights, instead of the ratio of the square root of their weights. This false assumption is probably a greater source of trouble to the makers of double cloths of all descriptions than anything else. No matter what may be the character of the fabric, the true ratio of the diameter should never be lost sight of from first to last. 96 DESIGN IN TEXTILE FABRICS. [Chap. V. Cloths of this class are frequently used, more es- pecially where it is desired to have a heavy, strong fabric with a very fine surface. The face may be made as fine and the back as coarse and heavy as we please, so long as we preserve the proper proportion between the two; in fact, the back becomes simply a "lining," something to give weight and strength. Fabrics of the most beautiful texture on the face, and yet of a very heavy, useful character, may be made upon this principle, and it is capable of application in a great many ways. ^ At the same time, although the texture may be varied, the patterns are not much varied in cloths of this class, but are confined chiefly to plain or simple twills, for the reason that it would be absurd to make the back pattern a fancy one, when it is intended only as a lining. 59. Cloths where both Quality and Pattern are Different. — If we wish to produce a fabric with a fancy face, and gain weight and strength by putting in a lining, we must resort to the fourth class of double cloths, where pattern and quality are both different. Here we have at command all the capacity of ornamentation which single cloths give, combined with the means of : obtaining weight and strength, by the use of double .cloths. Double cloths of this type are perhaps more used than any other. Throughout the woollen trade, in making cloths for men's wear, they are almost universal, and in many other branches they are also largely used. Generally such cloths are made with some fancy pattern on the face fabric — fancy, not only in the order of interweaving, but also by the use of colour while the back cloth is either a perfectly plain one or a simple twill. The face cloth is usually very fine, made from fine material, while the back is coarse and heavy. ' Of course the face cloth may be made as elaborate as possible, and the back as plain as possible ; in fact, the plainer the back, provided it will admit of a sufljcient quantity of material being put in, the better, because Chap, v.] BINDING DOUBLE CLOTHS. 97 the plainness adds to the strength by the warp and weft being so intimately interwoven. The arrangement of the pattern on paper for this class of fabric is, of course, precisely the same as for cloths which are equal in both quality and pattern, only instead of the threads of warp and weft being alternate, they will generally be two of face to one of back, or in such proportion as is required to give the proper weight or thickness of cloth, or to produce any desired effect. In making double cloths of this class the cultivation of the habit of dealing with each independently of the other is of the greatest value, so that the designer may know exactly what is the structure of each, and be able to see what is the pattern upon it at a glance ; he can then compare their relative orders of working, and select his binding places with certainty. Of course the same principle of binding must be followed in this class of cloth as in the preceding, but in many cases there is much greater difficulty of binding than in the others. In the first place, the difference in the quality and thickness of the yarns makes it necessary to select binding places where there can be no risk of their showing through to the face ; and it is most advisable, to assist perfect binding, to select the two thinnest materials ; for example : if the back cloth be a very coarse, heavy one, in most cases the weft will be thicker than the warp, and the back weft will certainly be thicker than the face weft ; so that it would be very desirable, in such a case, to bind the two together by lifting a back warp thread, and allowing a face weft thread to pass under it. Of course this must be done in accordance with the rule mentioned for binding two equal cloths together — namely, that the back warp must be on the upper side of the back cloth, or next the face cloth, and the face weft must be on the under side of its cloth, so that neither is drawn out of its regular course more than the mere thickness of the thread. H 98 DESIGN IN TEXTILE FABRICS. [Chap. V. Then the second, and in many instances the greatest, difficulty arises from the relation of the two twills to each other. If the two patterns, for example, oc- cupy such a number of ends each that they are not both complete at the same time, or, in other words, that the number of ends occupied by the back pattern is not a measure of the number occupied by the face, then at every repetition of the face pattern the back will fall in a different position in relation to it, and a binding place selected at one point which might be perfect would be en- tirely wrong at the next repetition of the pattern. We will take, for example, a ten-end pattern for the face and a four-end pattern for the back, and make a section as shown in Fig. 72. This pattern cannot be complete until twenty ends of each are gone over, because that is the first number of which ten and four are both a measure. Had the relative quanti- Fig. 72. ties of face and back cloth threads been two to one, then it would have required forty threads of face and twenty of back to complete it, and consequently the difficulty of binding would have been greater. However, we will examine the binding of this pattern. We have selected our first binding point at a ; the next repetition of the face pattern is at h, but if we bind at h we are not taking an end from the back twill corresponding to that we have taken at a, and if the binding at a is perfect that at b cannot be. Again, if we take every corresponding end of the back twill, they will fall at c, d, and e. Now, every one of these points occupies different positions in relation to the face twill, and if the weft be brought from the face under the back at these points, some of them would be Chap, v.] BINDING DOUBLE CLOTHS. 99 very imperfect. Take, for instance, the point d, where we should have to bring the face weft through its own warp to bind, under the back end. Instead of weft of one cloth and warp of tKe other being together, we have the warp of both cloths together, the weft of one cloth above and that of the other cloth below them, so that it would be quite impossible to bind them perfectly at such a point. It will be obvious that nothing but great care in selecting the points at which the binding is to take place, and in arranging the relation of the two pat- terns to each other so as to facilitate this selection, can ensure perfect fabrics, more especially when the two pat- terns occupy different numbers of ends, and fall in different positions in relation to each other in consequence. Of course, having found one or two places where binding can take place if the two patterns run concurrently, as they very frequently do, there would be no further trouble. We can bind as often as we please simply by following up the line of pattern, and always binding at corresponding points. Sometimes, though, we are de- barred from this, and we have another kind of difficulty presented to us. Suppose we have on the face a fancy twill running, say, in a vertical direction up the fabric, one which may be the result of the combination of two or more twills, or simply produced by the process of elongation, as, for instance, in Fig. 49 or Fig. 55, and we are putting a back cloth of an ordinary twill along with it. The two patterns running at different angles, we should have to find fresh binding places at every point where we wish to bind. Because of the diffei-ent angles, the two pat- terns could not occupy the same position in relation to each other at any two points, except at such distances apart, determined by the repetitions of the back pattern bringing it into concurrence with the face, as would probably be too great for binding purposes. At any rate we can never deal with the binding of such patterns in the same easy manner as we can where the two twills run con- currently. When we are using such patterns as this 100 DESIGN IN TEXTILE FABRICS. [Chap. V. for t}ie face it is generally better, if we can, to use a plain back, not only because of the binding, but quite as much because the difterent angle of the two twills may make one cloth draw the other a little out of its proper place, and so cause " cockling." We cannot always use a plain cloth, perhaps, because of the weight of fabric we wish to obtain, but we should do so wherever we can, and avoid whenever possible — and it is possible in most cases — the combination of two twills which do not run at the same dngle. 60, Forming Patterns on Double Cloths by Bind- ing. — The binding of double cloths may be used for the purpose of producing patterns ; and in certain classes of goods with which we shall presently have to deal the whole of the figuring is produced by binding, but in considering the subject generally we may point out how the figure may be most effectively produced. Of course such patterns are obtained by binding the two cloths to- gether as firmly as possible all round the outline of the figure ; for instance, if we wish to make a check pattern upon a cloth by binding, as is frequently done in worsted coatings, and also in many woollen goods. Along the line of the check, both warp and weft way, we make the two cloths become one, not at intervals, as in ordinary binding, but throughout the length of the piece upon the warp threads, and across the piece upon the weft threads, which mark the line of the check. These patterns may be made as fanciful as we please, but generally in the cloths we have named they are con- fimed to stripe or check form. 61. Relations of Pace to Back Cloth in both Quality and Pattern. — Before we enter into the question of the application of double cloth to particular fabrics, we must consider the relation of the back to the face cloth in all its aspects. We have already examined the relation of the two cloths to each other when they differ in pattern only, and when they are the same in pattern but differ in quality. We must now proceed Chap, v.] RELATION OF FACE TO BACK. 101 to the examination of those which differ both in quality and pattern. As has been already pointed out, the fabrics which differ in both quality and pattern are far more numerous than the other classes ; and we may say that it almost necessarily is the case, for if we are making a fancy fabric, and putting a back cloth upon it which is intended merely for a lining, we usually make the lining as simple a pattern and as cheap a fabric as possible. As a matter of course, the face cloth — that which is to be seen, and which is to be the wearing surface — must receive the first attention. We must make that not only a fancy fabric in the great majority of cases, but we must make it as unexceptionable as we can. It must be what is termed a well-balanced cloth, perfect in structure. The relative quantities of warp and weft must be properly apportioned according to the pattern, and, in fact, every care taken that it is treated properly, as if it were a single cloth. We must then consider the back. Usually, as we have seen, the back cloth may be made as plain as possible,^ and if not actually a plain cloth, it must be a twill of the simplest character, and only just sufficiently loose in its order of working to permit of the quantity of material being put in to give the required weight. It too often happens that the pattern of the back or the thickness of the threads are determined by arbitrary rules, or perhaps more frequently by guess-work, or "rule of thumb." Now, if the two fabrics are to be perfect, and neither cloth to interfere with the other, as we have shown they may do, they must both be con- structed equally firm. Not that the back cloth must be as fine as the face, or that the pattern must be in the same order of interweaving, but that the thickness of the yarn and the ends per inch must be suited to the pattern in one cloth as perfectly as it is in the other. The quantity of material in one must not be such as to make a firm, stiff fabric with the pattern in which it is being woven, while that in the other is making a loose, 102 DESIGN IN TEXTILE FABRICS. [Chap. V flabby article ; they must be as nearly equal as possible. If the face cloth has two threads of warp and weft to one of the back, it does not necessarily follow that the weight of the back threads is double the weight of those forming the face; but we must take first theii- relati^-e diameters into account, and then the relative order of interweaving. Suppose, for instance, we determine that the back shall be a plain cloth, and the face a twill, say a four-end twill, two weft and two warp on the surface, and that we have two threads of face cloth to one of back, both in weft and warp,— the question will be, what should be the relative thickness of the face and back threads to produce a perfect cloth, and one in which the two are alike perfect. Now, although in both patterns weft and warp on the surface of their respective cloths are equal, yet the order of interweaving is not equal ; the twill will be a much looser fabric than the plain. Therefore, although the number of threads is as two to one, the diameters of the threads must not be in the same ratio, but we must take into account the order of interweavinf^, which in the twill to the plain will be as six is to eight| the number of ends of face to back, which is as two to one, and the diameter of the threads, which are to each other as the square root of their counts. We shall then make each cloth equally perfect; the "take up" of one will be equal to that of the other, and there will be no fear of one acting upon the other, and so affecting its appearance. Well, it may be said, " in practice we cannot take all these things into account ; we are working upon certain counts of yarn, and we cannot alter exactly to suit any fancy system of calculation of this kind." The only answer is, " Then your fabrics cannot be perfect." Very frequently fabrics are made without any previous calculation of the relative thickness of the two sets of threads, and they come up so nearly perfect that they pass as such ; but in these cases the maker is guided entirely by previous knowledge of fabrics which have been Chap, v.] KELATION OP PACE TO BACK. 103 made, and which are approximately perfect, and using this previous knowledge he may again arrive at something sufficiently near perfection; but that is not quite enouo-h, for he may have to make a number of experiments, waste time, labour, and material, and in the end his results are only aj^jyroxiynately true, whereas a proper consideration of the condition will give him with certainty the proper counts of the material for one cloth to make it perfect in its relations to the other. So far we have been speaking on the assumption that the weft in each cloth is equal to its own warp, but frequently the warp and weft may be very different. In the face cloth this may be governed by the pattern, as was pointed out in dealing with single cloths, and m the back cloth it may be governed by questions of economy. Perhaps, in some cases, although the warp threads are as two to one in the two cloths respectively, the character of the patterns may render it necessary that the wefts may be in different proportions. Again, it may be that our back warp must be of cotton and the weft of woollen, then the weft would be much thicker than the warp ; yet we must not lose sight of the proper relation of that weft to the face weft, and to the order of interweaving, and so keep our two cloths as perfect as possible m their relations to each other. If any difference does exist between the two cloths, generally the back one should be the looser and softer. Serving as it does the purpose of a lining, we can afford to have a greater degree of loose- ness and softness in it than we can usually in the face, because the face has to be subjected to wear, to friction, and in a great measure to strain, which does not fall upon the back, and any liability to "cockling" is far less objectionable in the back cloth, which is never seen m wearing, than in the face cloth. However, this dif- ference must not be too great ; it must not be such as to be very perceptible either to the eye or the touch, and more especially in cloth such as woollen — a material in which this class of fabric is more 104 DESIGN IN TEXTILE FABRICS. [Chap. V. made than in any other— where a process of milliner or felting has to be undergone. In some cases this mcveased softness of one cloth may be an advantage: It will give more elasticity to the cloth as a whole and make the face cloth assert itself more, and con- sequently show to better advantage ; but it must not be carried too far, whatever degree of softness be given to It : it must not be much looser than the face else the advantage gained by increased elasticity will be more than counteracted by excessive looseness and loss ot wearing power. .f^ "Ply" ClotliS.-In addition to double cloths pure and simple, there are many others known as -three ply," -four ply," &c., imply- mg that the c oth is not merely a"^ double but ^a three or four-fold cloth. It does not always follow though that a three or four ply cloth means that there are three or four distinct fabrics woven together, though that may be so ; there may be two perfect and complete cloths, and a filling between them which is not in itself strictly speaking, a complete cloth. Or it may be that we_ combine two double-faced cloths, as, for in- stance, is the case with some very thick bulky cloths which are used for covering rollers and other purposes. A section of a cloth of this kind is shown in Fig 73 where we have two double weft face cloths combined to . ^ — V / — . ^ ^ make one. These . ' ^ "7 T ^^-^^V^^ ^^^-^^^V^-^P- two cloths, if 'fl — bound Kg. 73. together, as they 1 . may easily be make an immense thick bulky fabric; in fact, when milled,_ if the proper thickness of threads be employed in their manufacture, they will present a section fully a quarter of an inch in thickness. This in common speech would be styled a four ply cloth, and may be so called with a certain amount of propriety be- cause each of the cloths of which it is composed is a Cliap.V.] THREE AND FOUR "PLY" CLOTHS. 105 double-faced clotli; there are only two warps, but there are four wefts, and the manner in which these weft threads are interwoven with their respective warps allows the whole four to go into the space of one in an ordinary- single cloth. This is one of the most simple applications of the three or four ply cloths, but it will help us to understand how the multiplication of cloths will enable us to produce fabrics of any bulk. Of course the principle of structure is exactly the same as in a pure double cloth. We have only to consider how many warps and wefts we have, and deal with each independently, as a weft or warp ; but in combining we must consider its relation to the other wefts or warps, or the other cloths, so that they can be bound together in the most perfect manner, and so that each cloth, although bound to another, is still a cloth in itself. It would be an easy matter to multiply illustrations, and perhaps by doing so we might add force to the one object we have in view — namely, urging the student to practise the consideration of all the individual threads which go to form a fabric, and to classify them, and con- sider them, in the first place at any rate, as being there for one specific purpose, and that they form part of a whole for that purpose only. So that we may be able to do this more completely, and to prepare for the consideration of other fabrics in a more thorough manner, we will examine some of the applications of double cloths as they are generally used and applied to fabrics which come under the almost daily notice of every one, whether engaged in the textile trades or not. If we can direct the attention of the student to objects which are daily before his eyes, but of which, perhaps, he takes little or no notice, we shall probably do more to educate him than by any amount of rules or definitions. He will examine and think for himself, he will begin to inquire the reason, and in many cases he will familiarise himself with the principle of the structure of fabrics, which in after- 106 DESIGN IN TEXTILE FABRICS. fChap. V. life he may apply to goods of a totally different cha- racter. It IS not sufficient for the designer or manufac- turer of textile fabrics to know merely the structure of some particular class in which he is immediately engaged • he should have a general, and, as far as possible, a par- ticular knowledge of the structure of other classes of fabrics, so that he may import new ideas into his own branch of industry ; and it is for this reason that we lay so much stress upon a complete knowledge of double cloths, because it will be found to be the keystone of a vast variety of fabrics to which, at first sight, perhaps it has no relationship. ' 63. Scottish or Kidderminster Carpets.— One of the most largely manufactured class of fabrics to which double cloth is applied, is what are known as Scottish or Kidderminster carpets, which consist of simply two separate cloths of the same texture but of different colours. These cloths exchange places so as to form figures or patterns. In many of these carpets great variety of colours IS employed, and patterns of the most elaborate description produced, but a careful examination of them will show the student that each cloth remains to itself throughout. They exchange places to form patterns, but each weft weaves into its own warp. This is one of the simplest forms of application of double cloth to figuring. The fabrics may sometimes be made three or four ply, and the figures be of the most elaborate character, yet the application of the principle of double cloth IS extremely simple. 64. Quilts.— Another large class of fabrics made as double cloths, and one in which the most elaborate patterns are produced, although no colour is employed the articles being white only, is what are generally known by the name "quilts," which includes cover- Jets for beds, and also toilet covers and other such articles. These goods are usually of that class of double cloths which are equal in pattern but different in quality. Chap, v.] QUILTS. 107 Usually both cloths are quite plain, but the face is very much finer than the back, and in some of the conmioner qualities, which are known as "mock," or imitation quilts, there is no back warp but only weft. The system or mode of producing figures in this class of fabrics is very difierent from that of other double cloths of which we have spoken, though it is in effect the same as that mentioned in connection with coating cloths m section 60. • i i • So as to deal in the most complete manner with this important class of fabrics, it will perhaps be as well to begin with an examination of the best qualities, and show the mode of producing patterns, then the other and inferior qualities will be more readily understood, and a more comprehensive knowledge obtained of the whole system. . n j Quilts of the best quality may m one sense be called three ply cloths, though there are not three distinct and perfect cloths, but two cloths and a "wadding." That is, there are two distinct and perfect plain cloths, and a loose weft inserted between them, which not only gives bulk to the fabric but assists in producing that embossed ef- a ^ feet which is ^Txv'TX.i/Av^^WAlAV/^^ peculiar to r ■ \= p r this class of ^y^7\W/'«"N^^__^/''^%^^^ fabric. The rig. 71 section (Fig. 74) will explain most readily how the cloth is con- structed and the figure produced. There is a fine face cloth, represented by the thin Hnes and dots; a back cloth, represented by the thick lines and dots ; and the wadding, represented by the double straight lines. It will be seen that the face and back cloths are both perfectly plain, and the wadding pick passes clear between them. The manner in which the figure is produced is by binding the two cloths together, as shown at the points a and 6, all round the outline of the figure. By bindmg the DESIGN IN TEXTILE FABRICS. [Chap. V. cloths together in this manner, with the wadding weft between them, the figure is raised, and so produces the embossed effect. This is easily accounted for, because at the point of binding the two cloths become one, and so compress the wadding weft between them, while in the body of the figure the two are quite loose from each other, and the wadding loose between them ; so that the latter pushes the cloths apart, and of course the larger and more loose the figures, the more this will take place -babrics produced upon this principle not only give wide scope for producing very elaborate designs, but they also give a very substantial useful fabric. From the fact of the cloths both being plain, the strength is all that could be desired, and the wadding gives warmth. In this case the back cloth, of course, is a lining only; in fact the whole structure is as if we had taken two separate cloths, laid one upon the other with a thick wadding material between them, and then with a needle stitched through the whole mass all round the outline of the pat- tern, so as to bind them firmly together. It is very ob- vious that the drawing of the two cloths together with the stitching, leaving the body of the figure without any stitching, will produce an embossed effect, and the thicker the wadding and the larger the fi V < > II ( ) Jl <; ) Jl )i ( ) Jl r) ( ) Jl ( ) )l c FIG ] j J J J J J I WW WW I I I I U I I 1 1 11 n 11 J J I J J J I ) f f f f f f f f 1 1 1 1 1 i 1 1 i ( 1 1 ■i \ 1 1 ( I 1 1 1 1 1 Fig. 7- is J J I 1 L r L 1 1 i cs \ 1 1 1 FIG. 9.

VII.] GAUZE PIGUKED BY CROSSING. 165 interweaving, and the reasons which may induce us to adopt them. We have shown in Plate 9, Fig. 1, a plan of plain gauze ; of this we may produce some varieties. If, for instance, we have every alternate pair of threads crossing in opposite directions, that will give a slight variation, but it will be more effective if the weft thread be very thick ; it will throw it up as though it were a series of small spots. Again, further variety may be given to it by using thick and thin weft alternately, or by using a given number of picks of one thickness and a number of another ; or other similar means may be resorted to for the production of special effects. Again, a further variety of plain gauze may be made by having two pairs of threads crossing in one direction, say, from right to left, and at the same time two pairs crossing in the opposite direction. It may seem absurd to speak of forming patterns with plain gauze, but what we mean by plain gauze is where one end crosses one, and that at every pick, the mere reversal of the direction of crossing, or the use of threads of various thickness, although it produces pattern, still leaves the structure of the cloth equal to that of a plain gauze, so that we speak of it as such, but when we vary the order of crossing, then it may become a fancy gauze. A very pretty example of figuring with plain gauze, by reversing the crossing, and in which weft threads of different thickness are used, is shown in Plate 9, Fig. 2. Although in the order of crossing, with the exception that they are reversed, the cloth is quite plain, yet the combination of this reversal with the different thickness of the weft threads produces quite the effect of a figure. 89. Figuring by various orders of Crossing.— In a great many instances of the production of patterns by varying the order of crossing, a number of weft threads are allowed to come together so as to form one ; they then separate, some of them after separation continuing single for some time, then rejoining the group, others leaving one group to form part of another, and so by 166 DESIGN IN TEXTILE FABRICS. [Chap. VII. varying the division and bringing them together at different points forming a distinct pattern. An example of this mode of working is shown in Plate 9j Fig. 3. This method of figuring, as may be seen, is capable of great variation, and, as compared with plain gauze weaving, will give more weight of fabric ; for while in plain gauze every pick is kept quite distinct, whether we reverse the crossing or otherwise, in this mode of figuring more picks run together to form one ; and although they may separate and form part of other groups, yet the fact of a number of picks running together, even at different points of the fabric, will permit of a greater number of picks per inch being in- serted, and so give more weight to the cloth. In addition to the mere formation of patterns in the gauze in this manner, we may combine any two or more of these orders of working for the production of stripe check or distinct figured effects. For instance, we may take the patterns shown in Figs. 1 and 3 (Plate 9) and form a stripe with them, or in like manner any two work- ings or patterns ; but there is one thing we must very carefully observe in doing so. We say that Fig. 3 will permit of a greater number of picks per inch of the same yarn than would Fig. 1. If that be so, and we combine them together in stripe form, we cannot put as many picks per iach into the cloth as will make the stripe formed of Fig. 3 pattern perfect without at the same time forcing too many into that formed with Fig. 1. Indeed, what will most likely happen will be that the plain gauze stripe will not permit the number of picks being inserted which can make the other perfect ; and even if it did, the warp forming the plain stripe would become very tight as compared with the other, and the gauze would not have a sufficiently open and perforated ap- pearance as compared with the fancy one. Then we must adopt some means of counteracting this ; we must have both stripes equally perfect in their structure. We may easily do this by allowing two or more picks — ac- Chap.VIT.] GAUZE COMBINATIONS. 1G7 cording to the pattern of the fancy stripe— go to form one of the plain gauze. By doing so we can bring both to the same density of structure very readily, and also crive more openness to the plain gauze. It would be an easy matter to give a great many patterns of gauze made upon this principle, and some of them very nearly approaching the appearance of lace, and if we were writing a history of gauze we might show some most excellent and elaborate patterns produced in the days before the lace frame made such progress ; but at the present time their manufacture could not be carried on profitably. . , ^, « j e 90. Combination of Gauze with other Orders ot Weaving.— It is not so much in producing pattern by variety of crossing as by combining gauze with other forms of structure that such fabrics are made at the present time, and in this we may manufacture fabrics which do not come at all in competition with the lace or net goods. , We will endeavour to deal with all the most general combinations, and show both the method of forming pat- terns and the chief characteristics of each kind of combi- nations. , . , We will begin by taking those combinations whicJi most nearly approach pure gauze, and which are, in fact, intended to convey to the mind the idea of pure gauze^ and at the same time produce a heavier fabric, with more marked perforations, without making them actually coarse by usiiTg thick yarn. If we refer to Plate 9, Fig. 4, we have a pattern which is a combination of gauze and plain cloth, but which presents to the eye the appearance of pure gauze. The warp is divided into sets of four threads, and m the crossing two of those threads cross the other two ; at the same time there are four picks of weft which appear to go in as one. But those four picks are effec- tually separated by one pair of ends out of each alternate set interweaving with them as plain cloth, and the next 168 DESIGN IN TEXTILE FABRICS. [Chap. VII. set of four picks weaving plain with two ends of the next set of warp ends ; the result of this plain weaving being that, instead of the four picks which go into the cloth apparently as one, forming a thick rope, as it were, they are spread out and laid side by side, and form more of a ribbon-like structure. The effect of this, both in the appearance and in the structure of the cloth, is much better than if the four picks had gone in absolutely as one. The gauze effect is quite as good, the perforations being clearly marked, and the cloth is somewhat stronger, without appearing quite so bulky. In some instances, where it is desired to spread the weft even a little more than is done in the pattern before us, two of the four threads would weave plain with one set of four picks, and the other two with the next four. This would make the cloth a little firmer again^ and prevent any possi- bility of any of the picks getting too close together or one on the top of another. A very simple and effective method of combining gauze with plain is shown in Plate 9,^ Fig. 5, where two or more threads are weaving plain with the weft all through the piece, and a thick figuring end, as we might term it, is forming gauze by crossing and recrossing round the ground ends. In this pattern the effect is somewhat similar to that of the previous pattern, but the thick gauze thread gives it a good efiect. Again, sometimes the gauze thread Weaves plain into the ground along with the other ends, and then crosses round them, as shown in Plate 9, Fig. 6. In all the patterns we have shown so far all the crossing threads are crossing at the same time, so that the division between the picks is all across the piece. Certainly some of the threads are crossing in opposite directions at the same time. Even by this method of working we may produce some very pretty effects. The patterns shown in Figs. 2, 3, 5, and 6 (Plate 9) would have somewhat the appearance of net. The perfo- ration would all run in straight lines, but the threads would be drawn out of the straight line, and by some being Chap. VII.] GAUZE COMBINATIONS. 1G9 drawn to the right and others to thp left, a distmct net pattern would be formed. Although such patterns may be very pretty, much better effects may be produced by varying the crossing ; that is, by not letting all the threads cross at the same place. Take, for example, Plate 9, Fig. 7, in which the crossing threads form a distinct pattern. Another very good specimen is given in Fig. 239, p. 250, of my " Treatise on Weaving and Designing," 2nd Edition ; and did our space permit we might give numbers of illustrations all showing patterns of gauzes crossed in different manners, and producing some of the most beautiful effects in the fabric. When we have obtained all the patterns we can in the gauze, though they make pretty fabrics in them- selves, we may treat them as the basis for further ornament. We may combine any two of the different oi-ders of working, and produce stripe or other patterns, or we may figure upon the gauze grounds, or form figures of gauze upon plain or other grounds. We have already shown the combination of plain with gauze in one simple form. Before entering too fully into the question of figuring with gauze, we may examine a few more simple combinations of a different character. Sometimes the introduction of gauze into a fabric is not so much for the purpose of ornament as to obtain lightness of cloth or openness of texture, and, as we have already shown, there is no better means of obtain- ing light open texture combined with strength than the use of gauze, and by combination of gauze with plain or other orders of working we may regulate the weight and bulk of the fabric. Take the example shown in Plate 9, Fig. 8. We have three picks of weft weaving quite plain, then a crossing takes place in the warp ; there are three more picks of plain, and another crossing takes place. Now this cloth is as nearly as possible a plain one, the crossing which takes place is not what is termed a full gauze, but only a " half-cross ; " that is, after the 170 DESIGN IN TEXTILE FABRICS. [Chap. VII. crossing thread has changed from one side to the other of the straight thread it remains there for some time before crossing back again, all the time weaving plain with the weft. That being the case a division takes place, or the weft threads are held apart by the crossing of the warp threads at every three picks. This division will be equal to at least the diameter of the crossing thread of warp, and it will certainly be greater than that between two picks of the plain portion of the piece, and will therefore show an opening or " crack " all across the piece ; consequently there will not be as many picks per inch as if this crack did not exist, and as a matter of course the more frequently these cracks occur the less weft the piece will contain. Sometimes what is termed a full gauze pick is introduced ; that is, the warp crosses on both sides of one pick of weft, as shown in Plate 9, Fig. 9, the distances between the gauze picks being varied according to the weight of cloth required, or the eSeet desired to be produced. If we wish to combine plain cloth and gauze in stripe form, we must consider the relative structure of the two cloths. We will suppose in the first instance that we wish to have a stripe running the length of the piece plain cloth and gauze alternately, and we have the same number of threads per iach in both. The plain portion will be a very loose fabric and the threads would slip upon each other and fray ; that being the case we must either have a greater number of ends per inch in the plain stripe, or adopt some modification in the gauze. If we increase the number of ends in the plain stripe, or the diameter of the threads of which it is composed, or, what would be better, combine the two alterations, we may make it sufficiently firm, but we shall have increased the weight very considerably, and it is not desirable that there should be such a great difference in the weight of two portions of the same fabric as would necessarily accompany this arrangement ; then we must resort to the expedient of altering the Chap. VII.] STRIPED GAUZES. 171 gauze so as to enable us to put more weft in. This may be done by simply letting a number of picks go into the gauze as one. Suppose, for instance, it should require sixty picks per inch in the plain cloth to make it such a cloth as we require, we could not possibly put sixty of such picks into the gauze portion, with the wai-p threads crossing between each one ; but if we allow two, three, or four of these picks to go into one shed between each crossing, then we can get them in quite easily. If two picks go in between each crossing, it reduces the number of crossings to one half, and the two go together to make one pick, and consequently occupy much less room. The most common practice is to put three or four picks to- gether, but this will be regulated by the quality and weight of cloth required. If the stripes are to be across the piece, then a dif- ferent mode of working must be resorted to. We may, perhaps, put more than one pick together in the gauze, so as to give more decision to the perforations, but we must alter the warp threads. We have up to now been speaking of the gauze ends as single in the warp, but we may put any number together. Suppose we want our plain stripe to be finer than the gauze in the proportion of two threads to one ; then when we are weaving the gauze, two threads go together as one, and the gauze shows two threads crossing two, but the moment we begin to form plain cloth they separate and work inde- pendently of each other. This method of altering the gauze, putting a number of threads together either in the warp or in the weft, or both, is the most ready and efficient for forming either stripes or figures. If in making patterns which are combinations of gauze and plain cloth we do not desire to have quite so much or so striking a difi"erence as is shown between gauze and plain, the gauze having a number of threads together, both in warp and weft, we may obtain a medium between the two. We have in Plate 9, Fig. 10, an illustration of one mode of dividing the threads of weft after they have 172 DESIGN IN TEXTILE FABRICS, [Chap. VII. combined to form gauze, and also of intermixing plain in the gauze, and making that which is so intermixed different from the ordinary plain cloth in appearance. For the purpose of illustrating this most clearly, we have shown it as really forming part of a check pattern instead of a stripe ; that is, with plain cloth all round the gauze. The system of forming pattern in stripes or checks, by the combination of gauze and plain cloth, such as we have been dealing with, may strike the reader as being extremely simple. So it is. There is no more simple method of forming patterns upon light fabrics, or of ensuring the lightness of the fabric, and at the same time producing very pretty effects ; but in the decoration of gauze fabrics, or using gauze for the decoration of fabrics of other structures, the stripes or checks are the most simple, though even they are capable of giving very great variety, especially if threads of different thicknesses be employed, or if there be a variation in the number of ends and picks which are put together. 91. Figures formed by Combination of Gauze and Plain Cloth.— Though we can produce great variety by combination of gauze and plain in these two forms, we have far more scope when we begin to form figures with them. There may be said to be two distinct methods of combining these two orders of working to form figures : first, figures formed by plain cloth upon gauze ground; and second, figures formed by gauze upon plain ground. We will examine both in detail, so that we may see to what class of fabric each is applicable. If we are making a plain cloth, and we wish, to form patterns upon it by giving it the appearance of being perforated, we may introduce gauze working to form the perforations, and by doing so give lightness to the cloth without detracting from the firmness of structure, but rather adding to it. Take, for example, the small pattern, Plate 9, Fig. 11, where we have every alternate pick of weft forming gauze at some point, and the gauze being distributed regularly over the surface of the fabric. As it appears Chap. VII.] GAUZE FIGURES. 173 on the diagram, each of the weft threads forms straight lines, the warp bending round them at the point of crossing. This is shown so for the purpose of giving a clear view of the structure of the cloth; but in the actual fabric the weft threads would not form straight lines, but on each side of the gauze crossing would curve round, disclosing a distinct perforation on each side of the pick, and the thicker the warp threads the wider will the perforations be. The pattern we have here is one which in the cloth would convey the impression of the gauze and plain being in about equal quantities, although really only one-fourth of the interweaving is gauze, hut the plain picks are so much bent out of their straight line, and jammed together by the crossing of the warp, that they occupy less space than they otherwise would. This will prove, then, that greater firmness is obtained in the cloth by the introduction of the crossing than if it were all plain. If the weft threads can be so much bent out of their straight line, and, as it were, pushed closer together by the gauze, they cannot be so firmly^ inter- woven with the warp ; the relative quantities or thicknesses of warp and weft threads cannot be such as to make a satisfactory cloth, were it not for the presence of the gauze. These remarks will apply all the more if the weft threads are soft; that is, loosely twisted together or made of soft materials. We have in this pattern a medium between pure gauze and plain cloth. It contains more material, is closer in texture, and heavier than if it were pure gauze, but not so close, compact, or heavy as a plain cloth. It presents the chief characteristics of the gauze, with some of the qualities of a plain cloth, or^ in other words, it has the decorative features of gauze with the wearing properties of plain cloth. If we wish to make the perforations more marked, we can easily do so by letting the crossing take place with more than two ends ; that is, let two ends cross over two, or more ; or, let a number of picks go together to form one in the gauze. 174 DESIGN IN TEXTILE FABRICS. [Chap. VTI. By resorting to either expedient we may have the plain portion both closer and heavier, and the gauze portion quite as open, or even more open, than in the combina- tion of simple plain gauze with plain cloth. We must, however, consider the character of figure most suited to this class of fabric, and the effect upon the cloth. An examination of a figured gauze will imme- diately reveal the fact that where the crossing of the threads takes place, a greater length of warp yarn is taken up than where there is no crossing, even in a small simple pattern like that shown in Fig. 1 1 (Plate 9), but if the gauze be further extended it will be even greater. In fabrics consisting of a combination of plain and gauze, for the most economical production, the whole of the warp should come from one warp beam.' Such being the case the gauze must be distributed as equally as possible, so that one portion of the warp, by reason of a greater amount of gauze being formed with it, shall not become tighter than the rest. Then, if we are forming spots, they must be very equally distributed, so that every thread has its equal share in the formation of gauze. Again, the figures must not be too large, or occupy too much space at once, and the gauze must he considerably less in quantity than the plain, otherwise the plain portion of the cloth will be too thin, and the threads will be too loose upon each other. 92. Distribution of Gauze Figures on Plain Ground. — We have already pointed out in reference to spot figures what is the best method of arranging the spots so as to secure equal distribution, and what was said there will also apply equally to gauze spots, and it is even more imperative that the rule should be observed than in ordinary warp or weft spots, so as to secure uniformity of texture. But we may not always desire to produce spot figures ; it may be that we wish to have figure or gauze working running all over the fabric, in fact, to imitate to some extent lace ; then we may adopt scroll patterns, or any other which will give such effects as we Chap. VII.] PLAIN FIGURES UPON GAUZE. 175 wish to produce. If we do adopt such figures we must be extremely careful in their arrangement, so as to ensure equal distribution. We shall generally find that geometrical designs are best adapted to this class of figuring, not necessarily of the stifi'est character. We may introduce some freedom of design, but if we have a geometrical basis we shall be more certain of obtaining equal distribution. Of course, we are speaking now of the combination of pure gauze ; that is, one end crossing one, and only one pick between each crossing, with ordinary plain cloth, and the gauze forming the figure. 93. Plain Figures upon Gauze Ground. — When the figure is formed by plain cloth upon gauze ground, the conditions of the structure are difi"erent. We obtain only a very light cloth if the warp threads are one crossing one and at every pick. The mere fact of so much cross- ing taking place — the greater part of the fabric being gauze — will necessarily make it a light open fabric ; that being the case, any figure formed by plain cloth will be very loose. No matter whether the figure be large or small this will apply ; but it would of course be more apparent in large than in small figures. If extremely light fabrics are desired, this mode of figuring may be resorted to, and some very pretty eff"ects obtained ; but as in the case of gauze figure upon plain ground, there must be very perfect distribution, and if the figures are so small that the pressure of the warp in the crossing can push the weft picks a little closer together in the plain, the appearance may be very much improved, for not only will it make the plain look finer, but the curvature given to the weft threads will give a more novel effect than if they were quite straight and parallel to each other. It may be observed of gauze cloths, as differing from all other woven fabrics, that instead of keeping the threads of either warp or weft parallel to each other, the object very frequently is to draw them out of their parallelism as far as possible. 94. Warp or Weft Figures upon Gauze. — This com- 176 DESIGN IN TEXTILE FABRICS. [Chap. Vir. bination of gauze and plain is the most simple form of ornamenting gauze fabrics, no matter which of the two predominates or forms the ground. In addition to this system of figuring we may also resort to warp or weft ' figures, as in ordinary fabrics, but we must not be under the impression that when we do so we can figure as readily and with the same results as figuring on ordinary fabrics. In the first place, if our ground cloth be an ordinaiy plain gauze, of the type of which we have been speaking, and we suddenly cease to form gauze, and leave the weft and warp quite free of each other, neither of them would be present in sufficient quantity to cover the other. And as it is usually one of the first conditions in figures that the material which comes to the face shall quite cover that which goes to the back, so as to present a solid appearance, it could not give a satisfactory effect if the warp and weft were both visible, one through the other, in the figure. Again, the sudden transition from gauze — the firmest possible structure of fabric— to absolute loose- ness, the warp and weft not interweaving at all, would be too great. If we wish to have either warp or weft figure upon gauze ground, we must separate the figure from the gauze by plain cloth. This will to some extent modify the looseness of the figure, and, what is quite as important, it will give it most clear definition. If we were to change direct from gauze to figure, the figure could not be clearly defined, especially if it were large, and its outline at all indented ; but by bringing in the plain all round it, it is formed just as upon an ordinary plain fabric. Another question arises also; the figure must in all probability be bound down more or less. This binding will be more in harmony with the ground surrounding the figure if it be plain than it would be if gauze. We still, however, have the difficulty of want of fineness, not only in the plain which surrounds the figure, but more especially in the figure itself. If the figure is to be formed with the weft, we may resort to Chap. VII.] FIGURES UPON GAUZE. 177 the expedient we have before mentioned — namely, putting more than one pick of weft in one shed ; and this we may vary according to the size of the figure or quality of the cloth. By doing so we shall not only make the figure " cover " bettei-, but we shall add to the fineness and firmness of the plain portion without detract- ing from the openness of the gauze. If the figure is to be formed with warp, we may make a number of ends work together in the gauze, and then separate them in the plain, so making sufficient fineness, and making the warp figure cover the weft. We may also combine the two methods, a number of ends going together as one, and a number of picks going together as one in the gauze, thus increasing the fineness of the plain and the weight of the cloth to any degree, without interfering with the openness of the gauze, unless it be to make it more open. To begin with, suppose that we only want to increase the fineness in a slight degree in the warp, and to obtain the requisite increase of ends we let them work in groups of three, one crossing two — that is, one end working by itself, and two working as one along with it when form- ing gatize, but separating for plain, as shown in Plate 9, Fig. 12. When the crossing is of this description, the crossing threads may go all in one direction, or they may cross alternately in opposite directions, as shown in the figure ; but in either case when they separate they must form perfect plain cloth. In arranging designs upon the squared paper for this kind of crossing, perhaps more care is required than for any other kind, because the gauze threads being arranged in threes, and the plain having alternate ends alike, or, as it were, working in pairs, each end must be properly arranged, or a fault will occur in the plain. Now, if we form warp figures with the ends arranged in groups of three in this manner, and we do not separate the figure from the gauze by the introduction of plain, our warp threads will be laid in groups of three, which will look like one thick thread. M 178 DESIGN IN TEXTILE FABRICS. [Chap. VII. Our object must be to distribute the threads ; then we have no alternative but to inti-oduce some plain so as to eflfect this separation and distribution. The more general practice in figured gauzes is to arrange the threads in , groups of four, two threads together as one throughout, and crossing each other in pairs, as shown in Plate 9, Fig. 13, and separating to form plain as before. This has the double advantage over working with three threads of making the cloth still finer, and giving us even numbers of ends to deal with at once. In such cloths, however, the mere increase in the warp threads is not enough usually, we must also increase the weft threads by putting two, three, or four together in the gauze and separating them in the plain. Now, in many instances we may desire that our figures should be not merely loose warp or weft on the surface, but, perhaps, boimd in satin order, after the manner of damask or such figures, so that it is absolutely necessary to obtain fineness in the figuring ■ ])ortion ; but no matter how the figure may be formed, the almost invariable rule is to surround it with plain, so as to ensure the proper separation of the threads be- fore the figure is formed. This plain need not be more than a few ends, but it must be there. Another feature of gauze figures is that a true even outline cannot be formed as in patterns upon plain or satin ground, the threads running together in groups of, say, four ; all these four will cease to form gauze at the same time. One portion cannot be making gauze while the other portion is making plain or figure, therefore the outline will form a series of steps, not a steady, free line. This difficulty is even more apparent in flowing curves, the steps interfering very much, in some instances, with the beauty of the curve, and requiring the utmost care in reducing the interference to a minimum. Perhaps it will not be out of place here to say a few words upon the mechanical operations required in gauze weaving. Our excuse for doing so must be that existing treatises on weaving do not deal in a sufficiently Chap. VII.] THE USE OP DOUPS. 179 complete manner with the subject, as applied to the looms of the present day. The general principle of gauze weaving is fully- treated in the " Treatise on Weaving and Designing " before referred to, so far as the formation of gauze in small patterns and stripes is concerned ; and more fully in the excellent treatise on the " Art of Weaving," by John Murphy. But Murphy's book was written before figured gauzes of the class now mostly used were deve- loped by the Jacquard machine, which was at that time quite in its infancy ; and, again, most of the fancy gauzes of which he treats are such as could only be woven in the hand loom by careful weavers, because of the com- plication of cordage, and the delicacy of manipulation required; and besides, such goods have been entirely superseded by the lace frame. In the " Treatise on Weaving and Designing," the use and construction of the doup heald are fully explained, as also the use of several doups along with healds for forming patterns in the gauze, but nothing is said of Jacquard harnesses for weaving figured gauze. If all the doup healds are attached to one heald shaft it will be obvious that they will all rise together whenever that shaft is raised ; and if we use two or even three heald shafts for the doups, it is evident that our orders of crossing will still be limited. But even limited though it be, under certain conditions we may make great variety of patterns ; for instance, such patterns as that shown in Plate 9, Fig. 11, can be woven quite easily, either with healds, or a common Jacquard harness and one dotip. Although all the ends are not crossing at the same time, the crossing end is drawn through the doup and through one of the ordinary healds at the same time, but is carried under the thread with which it works between the common heald and the doup, so that as the common heald rises, it will take it to one side of its companion tliread, and when the doup rises it will take it to the other side, Now, if we have half the threads drawn 180 DESIGN IN TEXTILE FABRICS. [Chap. VII. through the doup heald, and each through a separate common heald, so far as the pattern goes — as, for instance, in the pattern before us, there are eight separate threads — we shall require eight common healds, each thread drawn through one of them, and the first of each pair also through the doup. If the ends are crossed from the common heald to the doup, from left to right, whenever we raise the doxip all those ends will rise on the right of the threads they cross ; then if the pattern is to be a combination of gauze and plain, as in this case, we lift the doup at every alternate pick of weft ; and if we wish to form gauze at the next pick we raise the common heald carrying the crossing thread, so bringing that thread up on the left of its companion, as shown in the figure ; and if we wish to form plain we raise at the second pick the thread which does not go through the doup. If we now substitute for the eight common healds, a J acquard machine, where we can actuate each thread separately, and we place in conjunction with that a doup heald, and draw the ends through the doup in the manner described, it is very evident we can produce any variety of figure which is a combination of plain cloth and plain gauze, or we may make warp figures upon tlie plain, or further, we can combine plain gauze with twill, or make one end cross three or any number ; but if gauze is forming at some point throughout the piece we are necessarily confined to one pick in a shed, and to one end crossing at once, and all ends which do cross must cross at the same time and in the saine direction. True, we may give some variety by using more than one doup, but still we should be confined to certain classes of figure; then if we wish to figure freely, and at will, we must resort to what is known as a gauze harness — that is, with doups formed in the harness of the Jacquard machine ; this provides that each set of threads has its own separate doup, which may be brought into use at will, so enabling us either to vary the direction of our crossing, or the number between each crossing as we please. Chap. VII.] GUAZE UPON TWILL, ETC. 181 95. Combination with other Orders of Working than Plain. — We may now proceed to examine a little more in detail the combination of gauze with otlier orders of weaving. We have shown pretty fully how it may be combined with plain, and how the fineness of the cloth may be increased to almost any degree, and also, to some extent, how figures may be formed with warp or weft, or both. When we are figuring upon a gauze ground, we may vary both the form of the figure and the order of interweaving of the weft with the warp as we please, provided, as we have already said, we surround the figure with plain, so as to prevent the gauze from interfering with the outline, and the ends from runnmg together in groups. Having done that, we are as free to figure or introduce twill, satin, or any other order of working, for the purpose of obtaining special effects, as if our cloth were an ordinary one with no gauze in it. Not only that, but we may vary our gauze ; we need not necessarily keep to the plain form of gauze working, either with single threads or a number thrown together, but we may adopt any of the forms of gauze such as those shown in Plate 9, to make the gi'ound- work. It is not necessary that we confine ourselves to the gauze forming the ground of the cloth. Yery frequently we may desire to produce a somewhat heavy cloth with a simple twill or satin gi-ound, and in order to give a light appearance to it, we may introduce a gauze figure. Or the ground may be a figured one, such as a rich damask, in w^hich case a small portion of gauze introduced into certain parts of it will give light- ness ; by this means some of the richest and most beautiful fabrics are produced. We often see in silk goods that some of the choicest fabrics are combinations of this character ; in fact, there is no limit. Quite apart from the combination of gauze with plain or warp or weft figure, we may also produce excellent efiects by combining two orders of gauze working, one forming the figure upon the other, but, of 182 DESIGN IN TEXTILE FABRICS. [Chap. VII. course, in such cases the cloth must necessarily be a light one ; and if one portion of the gauze be much firmer than the other, the remarks which we applied to the combination of gauze with other orders of weaving respecting the proper distribution will apply to it also. Having examined the combination of gauze with plain to form figures, we may now examine the combi- nations with other orders of weaving, for the production of effects of different characters. We have already referred to the formation of plain stripes upon gauze ground, and pointed out the necessity of either putting a number of picks together in the gauze, and separating them for the plain, or having a greatly increased number of ends in the plain stripe. In many instances the latter arrangement is preferable ; by increasing the number of ends we may, by using these ends of a different colour from the ground ends, show a distinctly coloured stripe. The closeness of the warp threads will so completely hide the weft that the colour of the warp only will be seen; conse- quently, the weft and the gauze warp may be of the same colour, and so show a difference between ground and stripe. We may also form checks on the same principle ; let the stripe in the warp be formed exactly as above described, and to form the cross stripe use thick weft, and instead of weaving gauze into the ground let it weave plain, so that the gauze warp will be hid in the thick weft in the same manner as the gauze weft is hid in the thick warp. This mode of working has also another advantage apart from the question of colour ; the contrast between the compactness of the stripe and the openness of the ground makes the pattern most striking. In some cloths more substantiality is required. Instead of forming plain stripes upon gauze ground, gauze stripes upon plain ground are formed, and with very pretty effect. We give one illustration upon Plate 10, where we have a drab ground and a pure white stripe ; of course we use white weft only throughout, and white warp in the gauze stripe, the ground warp being drab, Chap. VII.] GAUZE WITH EXTRA WAKP. 183 and so closely set as to completely cover tlie white weft. Perhaps a more effective method of forming stripes upon gauze is to work the stripe as a satin. We can then give any degree of fineness to it, and present a perfectly smootK surface. Some of the most beautiful examples of striped gauze have the stripe worked in satin. This class of stripe also gives some pretty effects when a little figuring is introduced into the gauze ground, and nothing is lost if the figure be run over ground and stripe indiscriminately, and more especially if the figure be formed with weft satin. ^ In such case it becomes necessary to put a number of picks together in the gauze, and also sometimes a number of ends also, so as to give sufficient fineness to the figure, and make it cover well enough. 96. Combination of Gauze Figures and Figuring with extra Warp. — From what we have said, it will be clear that a great variety of effects may be obtained by combining various orders of weaving with gauze, and using only the material which takes part in the formation of the ground fabric; but, as in other classes of cloths, this variety may be very much increased by the introduction of extra material, warp or weft. It must, however, be borne in mind that we have not the same' freedom for the use of extra material upon gauze cloths that we have upon simple plain or figured fabrics. In these cloths we may use extra warp or weft, or both, forming figure on the face, and then passing to the back, and being bound to the back of the cloth, instead of being cut away. We cannot do the same upon gauze— the open texture of the cloth would show it; we must either use only what will form the figure, or we must cut the waste away from the back. Again, for reasons we have pointed out in reference to ordinary warp or weft figures, we cannot very well figure upon the gauze itself, but must form a p^ain ground upon which to do so, in order that when we 184 DESIGN IN TEXTILE FABRICS. [Chap. VII. introduce extra materials to form figures, we must also hguve^ to some extent with the ground material also. In speaking of figunng with extra material, at present we are speakmg_ of it as an extra colour; in fact, as a ZfZ .^ Tl^ T^'l "^^""^^ the pattern, malTL f «h°r%l^--^to speak of the use of extra material for a different class of figuring ; however, in the ineantime we must confine ourselves to the use of It as ail additional colour. Figures made with extra warp, whether upon gauze or other grounds, must either be arranged sfcripewise, or the whole surface of the cloth must be figured. It does not necessarily follow that in all fabrics the figures appear to the eye as being in stripe form, even though they are so arranged, whether the loose material be cut away from the back ^r no 7 but gauze cloth unless the material be cut away from the back they must appear in stripe form. The fi<.ure as we have shown, must be formed upon plain ground ' If when xt IS completed we chang^ the stru^cture from ft wm bP^'"; and eave the .naterial on the back, It will be clearly visible through the gauze, and bein^ visible as so much loose material it would not add to the appearance of the fabric; then it must be cut away Before being removed the same rule must be observed Is mfiguring upon ordinary fabrics, of binding it round the edges of the figure, so as to prevent it slfpping out Then If we wish to avoid the cutting ofi" at the back we must make the plain continuous throughout. Althou-h this IS a disadvantage, as to some extent crippling us in our power of producing patterns, yet we may obtafn some m I'late 10. In this we give coloured and white stripes alternately, but we may have other colours at will and not only each stripe of a difierent colour, but several colours m each stripe.

Vn.] GAUZE WITH EXTRA WEFT. 185 we wisU to have two colours in the stripe, whilst one of them is forming pattern on the face, the other is forming plain cloth under it, and they are constantly changing places according to the pattern, each forming figure and plain alternately. 97. Figuring with extra Weft upon Gauze. — Figuring with extra weft upon gauze frees us from the necessity of making the figures in stripe form. If the weft be thrown all across the piece, we shall, of course, form stripes in that direction, but we may use the swivel shuttle, and so place our spots as we please, exactly as if we were figuring \ipon a compact cloth as shown in Plate 4, instead of upon a perforated fabric ; the same rule will, however, apply to these as to extra warp figures, of the cloth being plain under the figure. Indeed, no matter how we figure upon gauze, we must have plain cloth somewhere about the figure. We have no other means of distributing the warp and weft threads, or of securing the proper form of the design. When we are using extra weft, we have all the advan- tages and opportunities of ornamentation which can possibly be obtained, for we may not only combine figures with gauze, but we may combine all the forms of figuring • — plain figure upon gauze ground, gauze figures upon plain ground, loose weft or warp figure, figures formed after the character of damask, or with extra material in any colour or any number of colours. We may make extremely light fabrics, or we may give to heavy fabrics the appearance of lightness by the introduction of gauze figuring. Sometimes very pretty efiects are produced by figuring with extra weft of the same colour as the ground, but in different material, or in thicker yarn of the same material, so giving prominence to it merely by the thickness of the yarn. 98. Combination of Gauze and Plush. — We have not yet, however, quite exhausted the means of orna- mentation of gauze cloths. In addition to the methods we have already described, we may introduce pile or 18G DESIGN IN TEXTILE FABRICS. [Chap. VII. plush figures. There are two distinct methods of doing this : first, when the pile is formed upon gauze, and second, when the pile is formed upon plain surrounded by gauze. Now as to the figures formed by pile upon gauze ground, we have the means of obtaining pretty and novel eflfects. The ends of warp which are to form the pile assist also in forming the gauze. Plate 9, Fig. 14, shows a longitudinal section, indicating the manner in which the threads twist round each other, and how the loop of the pile is formed. In this it will be seen that one of the three threads is constantly twisting round the other two, and at intervals one of these issues from the cloth and forms a loop. The manner in which the loop is made will be fully ex- plained in the next chapter ; we merely wish to call attention here to the fact of its being formed. On each side of the loop formation a weft thread is inserted, represented by the dot, and the crossing thread passes from one side to the other of both the loop thread and its companion. This constant twisting taking place, the loop thread is held firmly between the straight thread accompanying it and the crossing thread, so that what- ever loop is formed it is held rigidly just as it is made. Sometimes it is cut, so forming velvet pile ; and even though there is really no solid cloth under it, it will be so firmly bound between the ground threads that there will be no fear of its slipping out or being easily pulled out. In the second class, as it may be termed, of plush figures on gauze, instead of the pile being formed actually upon the gauze, plain cloth is formed by a portion of the threads and the pile by the other portion, as shown in the section, Plate 9, Fig. 15. By this system, all the threads share in the formation of the gauze, as in the other, but when we come to the figuring they are separated into two portions — one for the ground cloth and the other for the pile — so that a solid cloth is formed in the ground. The pile is not held so firmly as Chap. VII.] PLUSH FIGURES UPON GAUZE. 187 in the previous case, but still sufficiently so to make a serviceable article, and it has the advantage of making a more solid structure. There is necessarily more warp employed, more threads running together in the gauze, and consequently a heavier cloth. The principle of the formation of the pile is the same in every respect, but it issues from the plain cloth instead of from the gauze cloth. The pile may be cut or uncut, exactly as in the previous case. Beautiful effects are produced by this combination of gauze and pile weaving ; but of course the pile is of the same colour as the ground, when the figuring is distributed over the whole surface. Sometimes, how- ever, the plush is made to form stripes ; then different colours may be introduced, or, indeed, we may have coloured figures all over. But as the pile threads have to take part in the formation of the gauze ground, if we have two colours of warp the ground will necessarily partake somewhat of the colour of the figure, though modified by the presence of the second colour; but where the figure runs in stripe form it may be totally different from the ground. To give variety to figured goods of this description, we may combine with the pile or plush figuring any or all of the other modes of figuring we have referred to. If the figure run in stripe form, we may combine with it figures formed by extra warp, or plain, satin, or other figures in the ground. If they are distributed all over the surface, we may introduce extra weft and any other forms of ornamentation, and so make our patterns as elaborate as we please ; and again, instead of the gauze being an ordinary plain one, with any number of threads running together, we may use any of the fancy gauzes — such as are shown in Plate 9— so that by the contrasts of colour, or such as are produced by the variety of structure in the fabric, we may ornament to an unlimited degree, and in all cases produce pleasing effects. 99. Lappet and Whip— net Figures on Gauze. We 188 DESIGN m TEXTILE FABRICS, [Chap. VII. have now but two forms of ornamenting gauze cloths to refer to, both of which have to some extent been an- ticipated—first by lappet threads, and second by threads crossing over wide open spaces. We give an illustration of lappet figuring in Plate 9, Fig. 16, and of the crossing threads over open spaces in Fig. 17.' In the first we have an ordinary plain gauze ground, with single threads forming figures by being stitched as it were over the surface; this stitching is done in the manner described at Art. 85. By this mode of figuring considerable variety may be produced, but all by a series of single threads. An appearance of solidity might be given to the figure by crossing and recrossing in quick succession, say at every pick, but generally such efiects as shown here are more aimed at. This mode of figuring is seldom combined with others, being usually applied to fabrics of very light texture. The same remark will apply to the class of figuring shown in Fig 17, but the designs are of a stifFer character. This arises from the fact that each thread is arranged to be brought into the cloth only at two certain points in relation to the warp threads, though their positions in relation to the weft may be varied — that is, the number of picks inserted be- tween each point of interweaving may be varied, but the number of ends cannot, in the same piece of cloth ; therefore the figures must partake of a stifi" character, this stiflfness only being modified by a varied arrange- ment of the order in which the ends are drawn through the doup, and consequently the manner in which they are manipulated. However, both lappet and this form of figuring will partake more or less of the stripe character, though the stripe may be almost hid by the variety of lines introduced. 100. The Materials from which to make Gauze.— One necessary part of the design of gauze fabrics is a proper consideration of the structure of the threads from which the cloth is made. From the nature of the Chap. VII.1 SUITABLE MATERIAL FOR GAUZE. 189 cloth, its open perforations, and the necessity for the pattern being very clear, threads of a smooth even structure, with little or no loose fibre on their surf ace, are best adapted. Silk being a long continuous smooth fila- ment is best suited of any class of yarns. Next come cotton and linen, for although they may have a little loose fibre on the surface of the thread, yet it. will be very little, and not likely to interfere much with the clearness of the pattern. We may also use worsted yarns, but they will not give the same clearness of pattern as the other three, especially if not made from the finest wools. Woollen yarns are quite unsuited for making gauze cloths, as are also the coarser cottons and tow yarns ; though, if well twisted, they may be employed in making the heavier goods when gauze is combined with twill or other forms of working, and where clearly defined patterns are not needed. It is not only so as to obtain clearness of pattern that smooth even yarns are required in making gauze, but it is necessary to have a strong thread in the warp at any rate. When the crossing takes place considerable strain is thrown upon the threads, and also great friction; probably the latter is most likely to do harm. If the thread is not strong and well twisted, it will soon give way under the friction, and if it has much loose fibre on its surface, there will be a great amount of friction in the threads passing each other, and also in passing and repassing through the eye of the heald, so that the smooth thread is as neces- sary to the successful operation of weaving as to the clearness and definition of the pattern. In fine woollen yarns with the thread sufficiently twisted as to give strength to the yarn to bear the work it has to do m the process of weaving, some excellent efi"ects are pro- duced by the combination of gauze with other orders of working, chiefly with twill in stripe form, but the texture must be very open, the threads being set a sufficient distance apart to reduce friction to the lowest point, so 190 DESIGN IN TEXTILE FABRICS. [Chap. VII. as to obtain all the ease possible in weaving, and even then the pattern of gauze will not be well defined, but will be partly hid by the loose fibre on the thread. Perhaps it is this want of definition which gives the charm to this class of fabric ; the perforations are not clearly marked, there is a kind of hazy mystery about the pattern which probably renders it more attractive than if it were well made out, and what adds to the attractiveness is that the character of the gauze is quite in keeping with the body of the cloth. At any rate, some really charming fabrics are made in this man- ner, but they require great skill in the use of the material, because of its soft fibrous character and the amount of friction thrown upon it in the process of weaving, 101. Madras Muslin.— It may be necessary to refer to and point out the chief characteristics of some fabrics which ■ bear a strong resemblance to gauze. In the first place, there are several varieties of extremely light texture, which at first sight, from tlieir very light- ness, would lead one to suppose they were gauze, but which are not necessarily of that material. The term gauze is often applied indiscriminately to all cloths of a light open texture, without regard to the mode of interweaving of warp and weft; but this habit is very misleading to the technical student. One class of fabrics, which gives pretty eSects upon a light cloth, is known as Madras muslin. This is a very light texture indeed, with a figure formed by the introduction of a thick thread of weft into the ground and then cut away where no figure is formed, so that it is really an alternation of thick, or moderately thick, and very thin, light cloth. Similar efiects are also produced in fancy coloured goods, two or even three colours of weft being employed to form figures, some- times one weaving plain into the ground cloth, and the other figuring upon it, and sometimes both entering partly into the ground cloth, and figuring alternately ; and, as in the previous case, when no figure is being Chap. VII. 1 NET WEAVING. 191 formed the extra material, wliicli would otherwise go to the back, is cut away. In the arrangement of .pat- terns for such fabrics we should be guided by the same rules as for figures upon ordinary fabrics ; the only difference being that the ground cloth is of a much lighter texture, and the figuring weft in a great measure goes in when the figure is formed, as an ordinary ground pick, or partly as a ground and partly as a figuring pick. There must be proper care as to the distribution of figures, and all the other precautions which usually accompany the arrangement of them. We must not omit net and lace in our comparison of fabrics, often confounded with gauze. 102. Net. — Whip net, a class of fabric formerly made, but now almost entirely superseded by lace, was really an extension of gauze weaving of a very complicated character. The pattern given in Plate 9, Fig. 17, may, perhaps, be called a species of whip net, though of the simplest kind. What is termed the whip or crossing thread, is made to pass over a greater distance than in ordinary gauze weaving, and fre- quently they not only cross what might be termed straight threads, but also cross each other, the crossing of the weft threads between them at the point or points of intersection keeping them in their places. Some- times these weft threads would be so thin as to be scarcely visible to the naked eye without careful exami- nation; and the whip threads being thick, all the appearance of lace would be obtained by the variety of crossing and interweaving. Although whip net produced some beautiful fabrics, it has been superseded by bobbin net and lace, partly because of the superior figured eflfects which can be secured, but mostly on the ground of economy. Bobbin net, as its name implies, is formed by having a series of bobbins, which are made to travel to and fro in a pair of " combs," or bars. A series of threads are placed vertically, and the bobbins, which are extremely 192 DESIGN IN TEXTILE FABRICS, [Chap. VTI. thin, are passed through between them from one comb to the other; they are then returned, hut not through, between the same threads. A lateral motion is given to the combs, or bars, termed " shogging," so at to move the threads to a different position in relation to the bobbins, thus causing them to pass through between different threads at each movement. The effect of this is to cause the bobbin thread to twist round the straight, or what may be termed the warp thread; and as bobbin and thread are moved at each passage of the bobbin, the bobbin thread is passed round each warp thread in succession, as shown in Plate 9, Fig. 18. Sometimes small spots are formed upon net by one thread traversing a number of times across the " mesh," but these are not large or elaborate, and call for no special skill, except so far as applies to regulating the move- ments of the machine. Net very nearly approaches lace in its structure, but in the latter more elaborate designs can be produced. 103. Lace. — It is not our intention to deal at length with designing lace for two reasons: firstly, lace is not strictly speaking a woven fabric, and secondly, because to do justice to the subject it would require a complete work in itself. We shall, therefore, only refer to the general character of the structure of the fabric, and the manner in which patterns are formed, so that we may be able to compare with other fabrics. If we examine the cheaper kinds of lace curtains, we shall see readily how the fabric and design are formed ; and we can then understand more easily the formation of other kinds of lace. In the curtains referred to there is first a straight warp thread ; along with this is another, which when no figure is being formed remains with the straight thread ; tliese two have constantly a third thread twisting round them. When figure is to be formed, the figuring warp thread passes from one straight thread to the next, is made fast to it by the twisting thread, then returns to its former position as shown in Plate 9, Fig. 1 9. Chap. VII.] LACE WEAVING. 193 This passing and repassing of the figuring thread is carried on with each one all over the fabric, according to the pattern to be produced. This is, perhaps, the commonest kind of lace, but it will serve to convey an idea of how lace is made. In other kinds of lace those threads which we have spoken of as straight, and which in the common laces remain straight, are drawn out of their course by the varying strain put upon them. A similar kind of twisting action takes place with the bobbin thread, but the warp threads are varied in their thickness. They are made to traverse varying distances, and are bound to different ends by the twisting of the weft or bobbin threads ; this, coupled with the varying tension, causes them to be drawn, and to make any pattern that may be desired. < It will be apparent that lace gives by far the greatest scope for producing ornamental open texture. The whole fabric is formed of such texture ; the shape of the openings, the lines made by the thick or the twisted threads are capable of infinite variation, so that the texture may be as light, as open, and as varied as ever the designer may please. In net we cannot have the same variety; the "mesh" will be of the same form throughout, most generally hexagonal, and any figuring will be limited, usually to small spots ; while in gauze weaving we have something which may be said to come in between the two, and is capable of producing effects which cannot be obtained in either net or lace, whilst, of course it cannot give the effects which lace can. In gauze cloths, as we have shown, we may vary the weight and texture in any ^ degree, and at the same time ornament by the texture. We may combine gauze weaving with any or all of the other forms of weaving, and form such patterns as we like. In fact, the combination of gauze with other textures affords more scope for the production of ornamental fabrics than any other class of fabric or N 194 DESIGN IN TEXTILE FABRICS. [Cliap. VIII. texture. In lace there is not this power of combination, and we are therefore limited to the production of light, open textures. CHAPTER yill. PILE OR PLUSH FABRICS. 104. The Classification of Pile Fabrics. — We have now but one kind of fabric to deal with, so far as the ornamentation in the structure is concerned, and that is the class known as plush or pile fabrics. This class differs in appearance from all others, having on its surface a series of short threads which issue from the cloth, and present the ends of the fibre to the eye, or the threads issuing from the cloth in the same way form a series of loops. We will examine each section in detail, so as to see to what extent the principle of orna- mentation can be carried in it, and also its combination with other orders of weaving. It may be said sometimes that pile fabrics are divi- sible into two classes, cut and uncut, or cut and loop pile, but that is not a sufficient division. They are separable into two kinds more distinct than cut and uncut ■ — namely, weft and warp pile ; that is, when the pile is formed by weft, or when it is formed by warp. 105. Weft Pile. — Let us deal first with weft pile, and examine it in all its forms. It consists in the first instance of a seiies of weft threads bound into the ground cloth at intervals, and floating over the sur- face loosely after the manner of a figure. This loose material is then cut by using a long bar of steel made into a knife at the end. This knife is extremely sharp, and is provided with a guide, which is simply a narrow piece of thin sheet-iron doubled so as to form a groove which fits on the knife. As it leaves the point of Chap. VIII.l WEFT PILE FABRICS. 195 the knife, the iron is welded into one piece, and is tapered off to a point, more or less sharp according to the length of the plush to be cut. This point is inserted under the weft floats, and as the knife is pushed forward it raises the weft up to the knife, which severs it, so forming the cut pile on the surface of the cloth. Take, for example, the section of a velveteen in Fig. 87, where two picks of weft are shown, one of ground and ■ 6 Fig. 87. one of pile. The ground weft forms with the warp quite a plain fabric, while the pile weft passes under one end only and over seven. By inserting the point of the guide of the cutting knife under this pile thread and pushing it forward the tapering form of the guide will raise it up until the guide just holds it tight, when the knife coming in contact with it severs it, as shown at a being an uncut loop, just as it comes from the loom. Thus the pile is formed. 106. The Structure of the Cloth, and Binding Weft Pile. — We must consider the structure of the cloth most carefully in order to determine the best mode of binding the pile into the cloth, so as to make it serve the most useful purposes, and also the best distribution of the pile over the surface of the fabric. The ornamentation of the fabric may be left for after consideration, or we may deal with it as we refer to the different modes of structure, as well as the uses to which pile-surfaced fabrics may be applied. The binding of weft plushes into the fabric to secure firmness is one of the most important questions in con- nection with their manufacture ; for if it is not firmly bound it will not, in the first place, permit of its being cut — ^the knife will pull it away from the cloth ; and in the second place, even if it were cut^ it would constantly 196 DESIGN IN TEXTILE FABRICS. [Chap. YITI. be coming out in wearing. There would be no power to resist friction, and these are matters which must not be neglected. The firmness of the binding is in some degree dependent upon the compactness of the fabric, the firmness with which the threads forming the ground texture are bound and beat together, and perhaps more especially the closeness of the weft threads, so that the pile weft which is introduced between them shall be gripped, as it were, in a vice. It is also in a measure dependent upon the manner in which the pile weft is interwoven into the ground. Very frequently the pile weft passes round only one end of the warp, as shown in Fig. 87. Then it may be said of such that it can make no difference how this bind- ing point is distributed, because it will have to depend entirely upon the pressure of the ground picks on each side of it to secure it firmly in the fabric. The fact, however, that numbers of patents have been taken out for difiierent modes of binding so as to make the pile more firm, and even when only passing under one end, proves that there must be something more than the mere pressure of the tveft threads, or that this pressure may be increased by che mere arrangement or distribution of the pile. Let us take the case of a pattern of velveteen we have now before us, examine the manner in which it is made, and how it might be made, and see what the efiect would be in each case. Fig. 88 is the plan of the cloth. It will be seen that there are four picks of P^^® weft, each floating over seven ends and binding under one only. Then there is a plaiii pick, the four pile picks are repeated, there is another plain pick. Those SmBBBSB ^"^^ plain picks will form a perfectly plain Fig. 88. ground. Now, with regard to the pile picks, an examination of them will show- that the four taken together would be equal to one plain pick — that is, every alternate end is occupied by them, and the same four ends are passed under by Chap. VIII.J VELVETEEN. 197 the plain pick immediately following. Then the four pile picks are exactly repeated, and the next ground pick passes under the ends which have been passed over, and over those which have been passed under. Thus the first four plush picks would constitute as it were one complete plain pick, the ground pick a second, and the next four plush picks a third ; so that we have an exact equivalent to three picks of weft in one shed, or under and over the same ends, and one in the contrary shed^ or under those which have been passed over before, and over those which have been passed under. Now those three picks coming together as one, or, more correctly speaking, the nine picks coming together as three in one^ will form one very solid mass when pressed together by the crossing of the warp for the next pick, and the driving of the latter up to the cloth, and each will help to bind the other into the fabric. The nine also becoming one, will allow a considerable number of picks per inch to be put into the cloth, so that we shall have weight, closeness of the pile, a solid compact cloth at the back, and the pile bound firmly into it. But there are other ways of look- ing at the subject. We may obtain too much weight of cloth if we beat the pick up close enough to make the pile firm. We have been speaking as if we were beat- ing the weft as close as possible in the process of weaving, but if the cloth we have produced is too heavy, and we simply reduce the number of picks per inch, and retain the same arrangement of binding, we shall loosen the pile just in proportion as we reduce the picks. That will not answer our purpose. How- ever much we reduce the weight we must keep the pile firmly bound. Then suppose we adopt the arrangement shown in Fig. '□□□SoBS 89 ; this would have the effect of making gggggBSB each set of four plush picks and the ground rig. gg. pick following it go together as one, so that instead of being practically three picks together as one, and then a single one as in the previous case, they would be 198 DESIGN IN TEXTILE FABRICS, [Chap. VIII. double picks throughout. This would possess two ad- vantages : first, the plush would be even more firmly bound, because each set of plush picks is followed by a plain pick passing over the ends they have passed under, and two picks going together as one would make the whole order of interweaving firmer for the same weight, or equally firm for less weight ; and secondly, the pile would be binding with all the warp, instead of only with every alternate end, as in the previous case, so giving more even distribution of ten- sion upon the ends than before, and consequently a better constructed fabric. Suppose, again, that the plush picks are arranged in their order of binding, that one portion of them goes into the same shed as the ground pick which precedes them, and the other portion into the same shed as that which follows them, they would require to be arranged so that equal quantities went into each. And even then they could not be held with the same degree of firmness as if they all went into one shed, because the pressure upon them by the ground picks would not be so evenly distri- buted, there would be a slight degree of waviness given to the ground weft picks which would make them hold one portion of the plush more firmly than another. Binding the plush with one end of v/arp is sufficient only when the weft is so closely beaten into the cloth as to exert great pressure upon the pile, and hold it by pressure only ; and in a large number of instances there is not enough of this pressure; in fact, it may be said that ^ majority of plushes there is not. Then when such is the case we must resort to other means or methods of binding; we must let the plush weft Fig. 90. interweave with more of the warp threads. We have a plan in Fig. 90 of a velveteen similar in its ari'angement to that shown in JFig. 88, but having the plush pick intei'weaving Chap. VIII.] VELVETEENS. 199 with three warp ends, instead of one only. There are five plush picks to each ground pick; the pattern occupies ten ends instead of eight, but as the plush weft interweaves with three ends instead of one, the lengtli of pile is just the same, floating over seven. The first five plush picks go under the same ends as the second around pick, so do the second five, so that five complete mcks go under every alternate" end, and only one— the first gi'ound pick— over them; thus it is equivalent to having five picks together in one shed, and only one m the other l^ow this plan will possess all the advantages pointed out in reference to Fig. 88, with the additional one of the plush being even more firmly bound by inter- weaving with more warp ends. The back of the cloth will present less of the appearance of a plain fabric than even will that of Fig. 88, but it will form decided ribs and there will be more strain thrown upon that halt ot the warp under which each plush pick passes. Certainly this strain will be somewhat neutralised by the thread having to pass over one only, but it will still be greater than the other portion of the warp If we arrange the plan as shown m J^ig. yi we shall neutralise this, and give more ■□□Hmga-Q plainness to the back cloth, and more r"""" 1 . m ^ v^cvT. □■□■□■□BUB firmness to the bmamg. ihere is, per- haps, one advantage, or so-called advan- ta^e in the arrangements shown in Figs. 88 and 90 over those shown in Fig.9i. Fi^s. 89 and 91— namely, in imitating warp pile. In the latter the pile runs distinctly in rosvs across the piece, because of its bemg formed with wires, as we shall show; and the arrange- ment of Figs. 88 and 90 will give more of the same appearance than Figs. 89 and 91. In each of the examples we have given there are four plush picks to one ground pick, and these four are distributed over the whole surface ; but it must not be taken either that there are always four plush picks to one ground pick, or that 200 DESIGN m TEXTILE FABRICS. [Chap. VIII. the plush picks between each pair of ground picks are distributed over whe whole surface; the number of plush picks will be regulated to some extent by the density of the pile required, and the distribution which takes place between each pair of ground picks will be dependent partly upon the number of plush picks to one ground pick and partly upon the length of the pile. For instance, if we were only having two plush picks to one ground pick in such a pattern as shown in Fig. 88, we should only occupy two ends out of the eight, while with the same proportion of picks in Fig. 90 we might occupy every alternate end, so that the order of binding will also interfere with it. The patterns we have given in Figs. 79 to 82 are what are commonly known as "tabby" velvets, or velveteens; the term "tabby," as used in the trade, being synonymous with "plain." And in such patterns it appears to be a general practice to occupy only every alternate end, and in most cases also to preserve the arrangement shown BBSBSgBBBBBSBB Figs. 88 and 90, of having one of □B"B""S5B"B""B the ground picks to go into the same dBBBBBBBSBSBBB shed as the plush on each side of it. □□BddBdB"B""h" There are some exceptions, and some ■□■□□BBBBBBBBB of these are amongst the patented □B55S5BSBS5B5B patterns. One feature of the perfect GBBBBB5BSBBBRB Guiding of plush into the ground, □□□□□BSBSdSSB" which has been made much of by ■BBBBBBBBBBBdB practical designers of fabrics, is that □□■□B5BS5B5B5B the ground pick succeeding the plush □BBBaBSBBBBBBB picks shall be contrary to those plush □B5BdB55b5B5B5 picks in the order of interweaving at □□□□□□BBBBSBSB the point where they bind into the Fig. 92. fabric. This is shown in Fig. 92, where the ground is not quite plain, but nearly so, and the departure from plain is evidently due more to a regard for the proper binding of the plush than from any desire to produce a pattern on the Chap. TUT.] BINDING VELVETEENS. 20i ground fabric. This is a most ingenious arrangement, and effectually secures the perfect binding of the plush into the 'cloth. The same principle of arrangement is applicable to plushes of any length, or with any number of picks of plush between the ground picks, or with the plush binding into any number of warp threads. " Tabby " velveteens, or velvets, are only suitable for the production of light fabrics. The pile may be tolerably dense, but the ground cloth cannot be very heavy, because of the order of interweaving preventing the threads coming very close together ; and as the pile cannot well occupy more than every alternate warp thread between the ground picks, the number of them issuing from the cloth in a given space cannot be so large as if there were more ground picks per inch. Then if we wish to increase the bulk or thickness of ^^^|-|^, the cloth we must substitute twill or satin for gl^aaBa the " tabby." If we do that our binding of ■■□■■g the plush cannot be so firm or perfect if it only gggygy passes under one end, but if interweaving with gggggg more than one end it may be equally perfect. j,.^ We have in Fig. 93 a plan of a velveteen with a three-end twill ground, and two picks of plush to each ground pick. In this it will be seen that again the principle of occupying every alternate warp end in binding the plush is employed, and also that every alternate plush pick falls in a different position relation to the ground twill, and conse- quently that one half the plush will be more □□□□■a firmly bound than the other. Again, in Fig. 94 ^® another pattern upon a three-end ^^^^ ground, but with three plush picks to ground pick. In this, only one-third of Fig. 94. tlie pile will be imperfectly bound. Now all these are patterns which have been regularly used, yet they are not free from defects in their binding. They have probably depended more upon the mere quantity of the material which the fabric con- DESIGN IN TEXTILE FABRICS, [Cliap. VIII. tained for the firm binding of the plush than upon any- thing else, but this is not satisfactory ; each pick should be equally perfect in its binding to ensure a good cloth, but with a twill ground, and more than one plush pick to one ground pick, this is difficult to attain when the plush passes under one end only, but if the plush inter- weaves with more than one end, then it can be bound perfectly. We showed in JFig. 91 the method of binding into more than one end upon plain ground, and also the best mode of making the pile firm. Precisely the same rule will apply to twill grounds, only that instead of interweaving with three ends it would be probably with four, or even perhaps more, after the j^ig 95 manner shown in Fig. 95. In this section it will be seen that the pile issues from the cloth between two ends, which are passed over by the succeeding pick, and which are in consequence pressed close together at that point, and so tend to cause the pile not only to be firmly bound, but also to stand more erect on the surface after it is cut. In most pile fabrics the systems of binding shown would be quite sufficient to hold the pile quite firmly in the fabric ; but sometimes the nature of the material, such, for instance, as mohair, renders it desirable to bind it more firmly into the cloth. Then, if the ground be plain, the pile may bind into as many ends as is desired, and a number of picks going to form one, always being arranged so that the point where the first pick, say, issues from the cloth, the next pick enters it so that the pick formed by the succession of plush picks shall be one complete plain pick, just as the five picks in Fig. 90 form two complete picks. 107. Distribution of Pile.— We now come to the question of the distribution of the pile, and here there are two distinct features to consider — first, equal distribu- tion, so that the whole surface of the fabric shall be equally covered ; and second, the arrangement, so that Chap. VIII.] DISTRIBUTION OP PILE. 203 what are termed courses for the knife shall be regular. Although, as we say, these are two distinct features, and both often exercise the mind of the designer, yet if the first condition be properly complied with, the second must be. Let us see what this distribution means. In the patterns Figs. 88 and 89 the four plush picks are arranged in what is commonly known as four-end satin, or satinette order. Each alternate end is occu- pied by a plush pick, but not in consecutive order. In this particular case they might have been arranged in consecutive order, as what may be termed the pattern is complete between each ground pick, but if there had been only two plush picks and one ground pick, then there would have been a tendency to show a twill, and this would not only have been apparent at the back of the cloth, but also on the face of the plush. Again, in Fig. 90, the plush is arranged in almost what may be termed a twill order, though not following on consecutive ends, yet from the manner in which they issue from the cloth, and the " pattern " again being complete between the ground pick, no twill will be visible. Generally, the best arrangement of plushes is that of a satin order, the number of changes being regulated by the length of the plush, and the number of plush picks required to complete " one round of the pattern." If we keep our plush distributed equally in this manner, we at the same time also insure regular courses for the cutting knife ; the pattern being ia regular order, the distribution per- fect, we are of necessity bound to have perfectly straight courses. But if this regularity is not preserved^ if the binding is distributed irregularly over the fabric, then the courses will be irregular, and the cuts will be " heavy and light " — that is, in one course there will be more material to cut through than in another, and so irregu- larity in the quantity of pile on the surface and difiiculty of cutting properly will be produced. 108. The Effects of Cutting Plush.— Cutting the plush has quite as much to do with the ultimate appear- 204 DESIGN IN TEXTILE FABRICS. [Chap. VIII. ance as the regularity and perfection of the binding, .though in the short plushes of which we have beeii speaking not so much diiference can be made, perhaps, as m longer plushes. We have already explained how the plush is cut by the knife and guide. Now, this guide plays a most important part ; its first function is to raise the thread up to the knife, but it must also determine exactly where the knife shall cut that thread, in the middle of the float or elsewhere. This is governed by the size of the guide itself ; if the pile is all to be of equal length — that is, the float of weft to be cut exactly in ct the centre — then the guide must be just of such size that it will fill the space between the weft and the cloth of one float only. Take, for instance. Fig. 96, where two weft floats are shown binding at two different places, as would be the case of any two picks in a plush pattern. If the knife-guide is of the proper size, it will pass under only one of these at once, but if it be not large enough, it will pass under two or more, as at the point a. In that case, mstead of the thread being severed into two equal parts, one. will be much longer than the other. Instead of bemg cut between the two binding points of one thread, it will be cut between a binding point of each thread', and so produce long and short plush intermixed. 109. Imitating Skins of Animals with Plush.— In such fabrics as velveteen, and others where the pile is very short, this would be a fatal objection ; the surface of the pile would present a most irregular appearance, but where the pile is of considerable length it may be an advantage. Very frequently plushes, more espe- cially weft plushes, are made to "imitate the skins of animals. Most people are aware that a great many ani- mals have next the skin a short close fur, covered with a longer hair, the hair lying over the fur and serving to turn off the wet, while the fur serves to keep Chap. VIII.] IMITATING SKINS. 205 the animal warm. In imitating such furs two lengths of plush must be formed. Sometimes this may be got suflB- ciently well merely by the cutting, using a guide so small as to catch two or even more picks, after the maimer shown in Fig. 96, and so producing long and short. If three picks at different points of the pattern are caught by the guide, there will of course be three different lengths of plush, and so on. Sometimes, however, this does not give sufficient difference in the length of the plush, and the floats of the weft are varied — in fact, two dis- tinct plushes are combined upon one ground ; say, for example, one having a float of an inch in length, or even more, to form the long hair, and the other having a float of only a quarter of an inch. In cutting these, one of two courses must be adopted : either the long plush must be cut first, with a guide which cannot enter the short plush, or both must be cut together with the short plush guide. In the first case the long hairs may be equal in length, or unequal, according to the size of the guide used ; in the second case the long plush will be all equal, and very nearly of the full length of the float, from one bind- ing place to another, because the guide for the short plush will be so thin, and the cuts so frequent, that the long floats will always be cut nearly close to the binding point, the short end of it being just of the same length as the short or under plush. If two different materials be used, as fine wool for the short, and silk or bright mohair for the long plush, some pretty effects may be obtained, and very correct imitations of the skins of some animals made. Sometimes even three materials, each forming a different length of plush, may be employed, and more variety given to the fabric. In making imitations of skins, the nature of the material employed to form the pile must of necessity be properly considered; for instance, in making imitation sealskin, smoothness and brightness of the fibre are essential conditions. Again, if the pile is required to stand erect upon the surface of the cloth, unless it is very short pile, the hair or fibre of which it 206 DESIGN IN TEXTILE FABRICS. [Chap. VIII. is made must be very strong, so that it can retain its erect position. 110. Density of Pile.— Another question now arises —namely, the density of the pile. If it must stand erect It must be tolerably dense; that is, there must be a great many pile threads issuing from the cloth iii a given space, so that they can support each other. To ob- tain this density of pile the number of plush picks to one ground pick must be properly proportioned to the length of the pile and to the number of ground picks per inch. It may to some extent be obtained by the use of thick pile weft, but this must not be carried too far, else it will appear rough and coarse. In obtaining density by an increased number of plush to one ground pick, we must not carry the proportion too far, Fig. 90 'will represent what should be the limit; in fact, it goes almost too far. The ground picks must be sufficient to form a fabric of such weight and strength as will carry easily the pile to be put upon it. Perhaps the pile weft may take part in the actual formation of the ground fabric. Sometimes it does ; then, of course, more strength is given to the structure. These are all matters in which the designer can only be guided by the circumstances of the case immediately before him. Empirical rules cannot be laid down, and if an attempt were made to lay such rules down they would only be misleading. 111. Special Effects produced by Yarns.— The same remark will apply also to the preparation of yarns for forming pile to produce special effects. For instance, in the imitation lambskin the yarns must be made from soft fine wool, with good felting properties ; the softer it is spun into the thread — so that it will hold together to be cut — the better. Then after it is cut it must undergo a teazing process to separate the fibres as effectually as possible; then they are felted until they form little " cots " all over the surface of the cloth. Again, in the imitation of dog and other skins, the yarns must undergo a preparation which will give them the proper amount of Chap VIII.] CORDUROYS OR RIBS. 207 wave or curliness ; and in some cases the subsequent processes of finishing assist or intensify these effects ; however, all such must be left to the ingenuity and skill of the designer, and a due consideration of the efiect he desires to produce. 112. Corduroys. — Plushes, in addition to being dis- tributed equally over the surface, are often made to produce patterns upon the ground cloth, such, for instance, as stripes, which when they occupy a small space are commonly called cords, or, when they run the length of the piece, corduroys. They may also run across the piece, or in diagonal form. Figures are also formed. In the small cords or corduroys the principle of binding referred to in velveteens is usually employed, only that the binding of the plush is not dis- tributed over the whole surface, but confined to a few ends. We have in Fig. 97 a simple cord on a plain ground cloth, which is known as a "velveret on tabby back." In this the bind- ing of the plush weft is confined to two ends throughout, so that when cut up between the the pile will form a rib or cord. In Fig. 98 the same cord on a three-end twill back, other- wise known as the " Jeanette " back. In these two patterns there is nothing which calls for special remark, except the formation of the cord : it is one of the most simple which can be made. In Fig. 99 we have one on a four-end twill ground, which is a more perfect form of cord. These cords, to give the best efiects, should be rounded on the top ; that is, the pile forming the centre of the cord should be longer than that forming the sides, so that it will stand above it and give a rounded appearance. In the patterns given in Figs. 97 and 98 this will take place to a slight ej '.tent, but in pattern Fig. 99 it will be more rig. 97. bindings we have Fig. 98. □□□□□■□□□□■a □□□□■□□□□□□a □□□□□■□□□□■a □□■BDaBHDDBa □□□□□■□□□□■a □■■□□■■□□■■a □□□□■□□□□□□a □□□□□■□□□□■a rig. 99. 208 DESIGN IN TEXTILE FABRICS. [Chap. VIII, marked. Take the two plush picks which occur between each ground pick. The first pick has a float of four and then of six ends altei.iately ; the second pick is the same, but the long float of one follows the short one of the ' other. The cutting will sever both threads in the centre of the float, so that the longest ends of pile will be in the middle of the cord, and the shortest ones at the sides or edges. This, then, will give a greater degree of roundness than in Figs. 97 and 98. Although the pattern in Fig. 99 will give a rounded cord, in many- cases it is desirable to have even more roundness and prominence imparted to it ; this may be done by giving three or four difierent lengths of float to the pile weft, and generally arranging them so gSBBSSBgSSBBBBRB that the longest are slightly pre- BB55BB55SB55BB55 dominant in quantity; such, for BSSBBSSgBSSBBSSB instance, as that in Fig. 100, which BB8BB5BS2SBBBBBB ^ould produce a very bold cord. □□BB55SB55SB55BB in this pattern one of the two plush SBBSSBBSSBBSSBBS picks forms the edges of the cord rig. 100. only, while the other forms the intermediate and the centre, thus giving more threads issuing from the centre of the cord than the edges. This would make the cord very full up the centre, but as part of this would fall towards the edges instead of remaining perfectly erect, it will supply proper roundness to tlie cord. Cords of this description may be made of varying widths, and with any degree of roundness; and they may not only be made as plain straight cords, but as fancy ones, and of varying sizes. 113. Diagonal Cords. — It is not necessary that we confine ourselves to cords running either the length of the piece, or simply across it, parallel or at right angles to the edges, but they may run diagonally, and the weft which forms the pile rib may either be intro- duced to form the rib solely, or it may take part in the formation of the ground. After the consideration we Chap. VIII.] FIGURED PLUSHES AND CHENILLE. 209 have given to straight cords it will not be necessary to say much about diagonal cords : the principle of structure and binding applies equally to both ; the roundness of surface on the cord required in one may be equally desired in the other, and the mode of obtaining it would be the same. In fact, instead of binding all the plush picks upon a given number of ends, they would be dis- tributed upon all the ends composing the fabric, and following each other in a diagonal direction. 114. Figured Plushes.— Figures may be formed with weft plush in the same manner as cords or diagonals, simply by binding the plush weft into the cloth where tigare is to be formed, as though the whole surface were to be covered^ and where there is to be no figure, either let the plush weft enter the ground as part of it, or float loosely over it. In the latter case, the loose material which is not forming pile will have to be cut away. Some very pretty eftects may be produced in this manner, as also in the formation of figures by different lengths of pile, or by the use of different colours of pile weft. In fact, we have in this system of ornamentation the means of producing great variety of effect, as well as most useful fabrics, not only for wearing but as warm articles of clothing. 115. Chenille. — Che- nille is another class of fabric, if we may so term it, which though used for a great variety of purposes, may be classed among weft plushes. The mode of its manufacture is by weaving weft into a warp having its threads set in small groups a short distance apart. After the piece of cloth is woven, the whole of the weft is severed between each group of warp threads, thus cutting the whole fabric up into o Fig. 101. 210 DESIGN IN TEXTILE FABRICS. [Chap. VIII. narrow shreds, as in Fig. 101. Here the warp threads are shown in groups of three, and are intersected by the weft in regular order • sometimes these warp threads weave with the weft in perfectly plain order, but in the best formed chenilles they are woven as gauze, thus holding the weft more firmly in the warp, making the cutting more easy and certain, and making a more durable article. After the chenille is cut it is twisted, all the three threads of warp being thus formed into one, with the short threads of weft projecting from it all round, making as it were a fringed thread. This twisting tends to hold the weft fringe stiU more firmly in the threads of warp, so that if in the plain woven fabric it can be held sufficiently firm to resist being pulled out in cutting, it will become more secure after the twisting operation. 116. Sham Plush. — One of the uses to which chenille is sometimes applied is the production of what may be termed sham plush ; that is, it is woven into a cloth as weft, and the loose f linge formed on the thread, as before described, projects itself through between the warp threads, and so gives the fabric the appearance of a plush. If it is woven into a plain piece, there is, of course, the same quantity of plush on each side of the cloth, but if thrown pretty loosely on the face it will present very much the appearance of an ordinary plush, and can be made much more economically. One thing which is necessary in making cloths with cheniUe weft is to have the warp threads pretty wide apart, so as to give the loose fringe an opportunity of projecting itself between them ; if put into a closely set fabric it would not have an opportunity of doing this, and would consequently be nearly, if not entirely, lost. Chenille, if judiciously used, gives some very pretty effects indeed, and at a cheap rate compared with what can be done with other kinds of plushes. 117. Warp Pile. — We now come to the question of the formation of pile or plush on the surface of Chap. VIII.] THE STRUCTURE OP VELVET. 211 fabrics _ with warp. The principles involved in the formation of pile of this description are similar to those of weft pile, the warp taking the place of weft, but the modus operandi is different. In the formation of weft pile two wefts and one warp are employed ; in warp pile, two warps and one weft. In the former the cutting takes place usually after the cloth comes from the loom, in the latter usually in the loom, or the pile may be left uncut and form loops ; so that we have two forms of warp pile, commonly known as "cut" and "loop" pile, or "cut" and "Terry" velvet. Whether the pile be cut or uncut the structure of the cloth is the same ; it is merely a question of using the knife or not. We will first examine what is known as common velvet — as there as several modes of forming the pile, or rather of binding it into the cloth— so that we may obtain a more ready and accurate idea of the general principles upon which the binding is effected. 118. The Structure of Velvet.— In the first place, velvet is formed by the pile warp issuing from the cloth, passing over a wire, and then passing into the cloth again, where it is interwoven, so as to secure it firmly. We may bring the whole of the pile warp at once over the wire, or we may bring only a portion of it, but in either V.g. 102. case we must consider the binding, so as to properly secure it ; and in the event of bringing only a portion over the wire at once, we have the double consideration of binding and proper distribution. Suppose we first bring the whole of the pile warp over each wire, as shown in the section in Fig. 102, we bind the pile threads into the ground in the order of plain weaving between each wire. In this section the loops are shown 212 DESIGN IN TEXTILE FABRICS. [Chap, VIII. just as they are formed by the wire, except at a, where they are shown as cut. Now, one feature of this section must strike the reader : the pile issues from the cloth after a pick is inserted, passes over the wire, and returns to the cloth before another pick is inserted. To secure the pile properly in the cloth it must pass under the pick which precedes the wire, and also that which follows it, and the ground thread next to it must pass over both these picks, so that virtually both are in one shed. It must not be supposed from this section that the pile thread necessarily forms part of the ground, that is, that the thread seen here and the ground thread accompanying it are the only two representative threads of the cloth; but a ground thread accompanies the pile thread in the order of interweaving in the ground, so forming a double thread throughout, except in passing over the wire, when they separate. Thus this arrange- ment secures the pile firmly into the fabric, and- the double pick has also another advantage — namely, that the pile threads issuing from and returning into the cloth between two picks which are contained between the ground threads in the sarne shed, and which are beaten as closely together as the thickness of the pile warp will permit, are held firmly together, thus supporting each other and standing erect upon the surface of the cloth. This method of binding the plush gives all the security to the binding which is required, but it will form distinct rows or ribs across the piece. If the pile warp be thick enough, and spread itself out sufScieaatly on being cut, these rows will be hid, but if the cloth be doubled back, each row will at once disclose itself. This is certainly a characteristic of all velvets, and is the feature we referred to in Art. 106, which is imitated by the velveteen when two sets of plush picks and one ground pick pass into practically the same shed, thus giving a sort of ribbed effect to the back of the piece, and showing the plush in rows. If we are making our cloth with fine ground weft these rows would be so close together as not Cliap. VIII.] THE STRUCTURE OF VELVET. 213 to be at all objectionable ; in fact, not visible to the unassisted eye. Again, in the process of weaving we must consider the effect of weaving in this manner. If the warp be a smooth thread and not over thick, as silk, for instance, we may raise or depress all the pile threads at once, without fear of " choking " the shed, but if the pile threads be very thick, or not of the smoothest nature, or too closely set, then there would be a probabi- lity of " choking " as they pass between the ground threads, and probably also the rows and the openings between them would be too decided. Then in such cases we must divide the pile warp into at least two portions, and bring each portion over the wire alternately. In doing so we alter the structure of the cloth. Practically, each portion of the pile warp is bound into the fabric, just as shown in Fig. 102, but as we have two portions to consider, each to be bound in a similar manner, the order of succession of ground picks in their relation to the ground warp must be altered. A section is given in Fig. 103, showing the method of binding the warp when bringing only half over the wire at once. The black line Fig. represents one portion of the pile warp, and the dotted line the other portion, the ground end being represented by the double line. In this, as in the previous arrange- ment, the pile issues from and returns into the cloth between two ground picks which are in the same shed, being held so exactly in the same manner. Again, on returning into the cloth it passes under one pick, over two which are in the same shed, and under another, when it again issues from the cloth; so that practically each portion of the pile weaves into the ground in precisely the same way as in the previous case — namely, three ground picks and a wire, two of the picks being practically 214 DESIGN IN TEXTILE FABRICS. [Chap. VIH. one, so far as this portion of the pile is concerned. Then the other half of the pile warp issues from and returns to the cloth between the next pair of picks, thus making a loop at every two picks of the cloth, but two picks always going into the same ground shed, being separated by the pile warp as it issues from and returns to the cloth. Such being the nature of the structure when the pile warp is brought to the surface in halves, there must be a better distribution of the pile. The firmness of the binding and the texture of the ground cloth will be practically the same in both methods of working, but in the second the rows of pile will not be so decided, their greater frequency, and the fact of only one half the pile coming to the face at once, tending to equalise the distribution, and give a more regular appearance to the pile, more especially if thick yarn, or yarn made from strong fibres, be used. "What we have said has more especial reference to velvet, or cut pile. If it be uncut, forming loops, so far as the binding or the pile running in rows is con- cerned, there is no advantage in either system, because the pile will always stand in rows, just as it is left by the wire, but by bringing half the warp up at once we can get the rows closer together ■; and although each row of the pile brought over each wire cannot be quite so much in quantity as if all the warp be brought up at once, yet the increased closeness of the wires, and the fact that we can have the warp more closely set, will enable us to form a greater quantity of pile on the cloth. 119. Pile formed without Wires. — Loop pile may be formed without the use of wires, but its appearance is not so regular; although formed in rows, the loops do not stand perfectly straight, nor exactly equal in height ; thus they intermix with each other, and give a very rough appearance to the fabric. This kind of pile is most used for bath towels and similar articles. 120. Ornamenting Pile Fabrics. — We must now turn our attention to the ornamentatioji of pile fabrics. This Chap. VIII.] ORNAMENTING PILE FABRICS. 215 we may deal with under two heads : first, the decoration of pile fabrics, and second, the decoration of fabrics with pile. The first idea which naturally occurs in connection with the ornamentation of fabrics is the use of colour. In ordinary velvets, whether cut or uncut, colour can only be used under certain conditions, and consequently can only give some specific character of ornamentation, and not be used in a general way. The pile formed on the surface of the fabric entirely covers the ground cloth; then any ornamentation which may be visible must be formed with the pile warp. If we introduce^ variety of colours into that they must necessarily run in stripes ; figures could not be formed. The warp consists of a number of threads laid side by side. If these threads are of difierent colours, a given number of one colour, and a given number of another, when woven into the fabric, and forming the pile on the surface, exactly the same stripe must be presented on the cloth as in the warp, so that our power of ornamentation in that direction is limited. Then our chief power of ornamentation must be by forming patterns in or with the pile itself, in a great measure without the aid of colour. When we speak of the ornamentation of pile fabrics, we naturally conclude that the whole surface of the cloth is covered with pile, or at least that the greater part is so covered, or that some ornamentation is formed in the pile itself, or by its being formed in varying quantities on the fabric. First of all, we may produce pattern by the pile varying in length. When such is the case it will usually be in stripe form across the piece, because the difference in length is produced by wires of different sizes being inserted under the pile warp during the process of weaving, so that it would not be very convenient to form figures in this manner. Of course figures can be so formed, but the expedient is not very frequently resorted to. The next means of ornamentation is by the combina- tion of velvet and terry— that is, cut and uncut \ and this 216 DESIGN m TEXTILE FABRICS. [Chap. VIII. IS very frequentlj^ employed, figures of terry being formed upon a velvet ground, and vice versd. Tlie same warp is employed in the formation of both kinds of pile, but two kinds of wires : one provided with a groove for guidint^ the "trevette," or cutting knife, or having a knife formed at its extremity so that it cuts its way as it is being drawn out, and the other being a plain wire which when drawn out leaves the loop intact. No prettier efiects can be produced than by this combination of velvet and terry ; although both are of the same material, and of the same colour, the contrast between the loop and the cut fibres marks the pattern very distinctly. One great advantage of this mode of ornamentation is that the texture of the ground cloth is not at all aff"ected, the interweaving of the pile with the ground remains the same; the same amount of pile is formed all over the surface of the fabric, the cut and terry simply taking the place of each other, so that the usefulness of the article is not impaired, either in its strength or in the wearing surface, there being no inequalities whatever in the pile. In fact' this _ kind of figuring bears the same relation to pile fabrics that damask does to ordinary figured cloths. Figures may be formed upon velvet grounds by ceasing to form pile at intervals ; for instance, taken in its simplest form,, if we weave say half an inch of velvet in the ordinary manner, then cease to insert wires, but continue to let the pile warp interweave with the ground, we should form plain cloth, having two picks of weft in each shed, and with two ends going together as one. We are now assuming that the pile is formed by bringing half the w-arp at once over the wire ; then we should have alternate stripes of velvet and plain cloth. But instead of forming simple stripes we may let our plain cloth form figures, and the figures may assume any form. Then we are ornamenting by the introduction of patches of plain cloth, such patches taking the form of figures, and being distributed according to the fancy of the designer, or the special eflTect intended to be produced. When figures Chap. Vm.] FIGURED VELVETS. 217 are formed in this manner, the plain portion of the fabric is a little more loose in texture than when pile is formed. As will be seen on referring to the sections of velvet in Figs. 102 and 103, when pile is formed, the warp separates the two ground picks, which otherwise go into the same shed, but if pile is not being formed, the pile warp simply lies under them along with the ground warp, so that there is nothing to separate the two picks, consequently they will lie closer together and occupy less space. Now, if one portion of the fabric has two picks together as one, and another portion has the same two picks separated by a series of double threads, one must of necessity be firmer in texture than the other. Perhaps this difference is not such as to have a material effect in the majority of fabrics, yet it is necessary to be aware of its existence, since if the pile warp be very thick, or the figures be not equally distributed, it may be detrimental to the structure, and a knowledge of the possible cause of defects enables us all the more efiectually to guard against them. In addition to irregularities in the texture, the wearing surface is also irregular, the velvet standing up as a pro- jection on the surface of the fabric; but for the purposes to which such goods are usually applied this is not a matter of much importance. Plain figures of this des- cription upon velvet grounds are about the most simple mode of ornamentation, though a very eflfective one, the design produced being of an embossed character. In fact, common velvets are frequently made to imitate them by being embossed, but these are not so good for wearing purposes as when they are properly figured, because that portion of the pile which has been flattened by pressure to form the figure will become loose with friction, and gradually rise to almost its former position and so destroy the pattern, whereas if the pattern be woven in, nothing can destroy the clear definition of the figure except the actual wearing away of all the pile of the ground — a cir- cumstance which cannot often occur. 218 DESIGN IN TEXTILE FABRICS. [Chap. VIII. 121. Combination of Pile and Figuring with extra Material. — Fabrics figured, in this manner are like those figured with velvet and terry, necessarily all of one colour J but variety of colour may be obtained, by the introduction of extra material, after the manner pointed out in reference to ordinary fabrics, and in this way some of the richest possible effects produced ; the density of colour which is always a characteristic of velvet, and the variety of light and shade produced by the pile, being wonderfully relieved, and giving the most beautiful effects by the introduction of bright or contrast- ing colours. There is probably no class of ornamentation applied to fabrics which gives such magnificent results as combinations of velvet with coloured figures. 122. Pile or Velvet Figures. — "We now come to the ornamentation of fabrics with plush or pile, and what has been said of the ornamentation of pile will practi- cally apply to this, in so far as structure of the cloth and wearing properties are concerned ; the mechanical operations required for the formation of patterns are also the same. In fact, we may almost sum up the difference by saying that in one case the plain or figured ground cloth becomes an ornament to the pile surface, the latter of which predominates largely in quantity ; and, in the other case, the small quantity of pile which forms a figure becomes an ornament to the ground cloths. The fabric which we wish to ornament with velvet figures may be anything- — plain, twilled, satin, figured, or gauze. It is made on the ordinary principles. The wai-p which is to form the pile may take part also in the formation of the ground ; it may form figures in the ground, or may be dealt with in any manner when not forming velvet ; then when it is reqtiired to form velvet it begins to interweave with the ground cloth in the ordinary manner of plain velvet, and is also passed over wires in the same manner. Sometimes the velvet is formed in stripes ; when such is the case there is no trouble with the arrangement of the design, further than to provide the pile ends in the warp, Cbap. VIII.] PLUSH FIGURES UPON GAUZE. 219 and consequently in the arrangement of the pattern upon paper, at the places and in such quantities as are requisite. The stripes may be plain or figured ; when figured, the pattern is produced by simply passing such ends over the wire as will form the figure desired, and leaving the rest in the ground cloth. If the figures be distributed over the whole surface of the cloth, at greater or less intervals, then they must be distributed equally ; in fact, the same rules must be observed as for any ordinary figures. Plush figures upon a ground fabric differ from plain figures upon a plush ground in one respect — namely, that the figure may be different in colour from the ground, more especially if the figures be small, because then the pile warp would be treated as extra material, and thrown to the back when not forming pile. Of course, in plain figures upon plush ground, a similar effect may be produced by the introduction of extra material, as we pointed out for the formation of extra spots ; but this is not so general a practice as introducing extra warp to form plush figures. Then again we may combine extra material for the formation of other figures, after the manner of ordinary cloths between the plush or velvet figures, or we may figure with the ground fabric. In fact, we may combine with velvet figuring all other forms of ornamentation which can be applied to fabrics, and our velvet figures may be either cut, or terry, or both. 123. Plush Figures upon Gauze Ground. — We have already referred to the formation of plush upon gauze ground, but that will call for a few more words here. As it is shown in Plate 12, Fig. 14, the pile is formed ripon the gauze ; that is, the twistings of the gauze threads take place between the loops of the pile, so that really there is no solid ground fabric under the pile. This is a very pretty and useful mode of working, but will only serve for very light fabrics, and does not permit of any other mode of ornamentation being applied along with it. Now, we may frequently wish to combine plush figuring 220 DESIGN IN TEXTILE FABRICS. [Chap. VIII. with some other upon gauze ground, or plush figuring with gauze upon some other ground. Suppose, for example, that our plush is to be surrounded with plain upon a gauze ground; then in the first instance we combine plain with gauze in the usual manner, then, as plush is to be formed, we cease the plain working and adopt that which will give a proper ground for the plush, and proceed to the ^ insertion of the wires. This mode of working, in addition to enabling us to make a heavier cloth than if the plush is upon the gauze direct, will also make the plush appear better by being more dense. Again, the plain cloth may predominate, and figures be formed alter- nately by plush and gauze, or we may further call the use of extra material to our aid; so that we may be said to have here all the different methods of ornamentation at our command at once, to apply as we please. There is, perhaps, nothing which produces such striking effects as the combination of plush and gauze, whether any other order of weaving be combined with them or not ; the contrast between the density of one, and the open perforated character of the other, always giving a very decided character to the whole design, and, at the same time a very pleasing one. To the designer there can scarcely be any more pleasing duty than the designing of figured velvets ; he has so much scope for the display of artistic merit, and also of complete technical knowledge of the structure of fabrics. 124. The Production of Special Effects in Plushes.— In dealing with warp pile so far, we have confined ourselves chiefly to velvet, or fabrics having a very short pile ; but there are numerous other kinds of pile fabrics in which the pile varies, though in principle of structure they are practically the same. But although they are the same in structure, yet great variety of effects is produced by varying lengths of pile, by special prepara- tion of the pile warp before being put in the loom such as printing, curling, waving, &c. — similar to the Chap. VIII.] BRUSSELS CARPETS. 221 operations we referred to in connection with weft pile; and, again, special effects are often produced in the process of finishing after the fabric leaves the loom, such as tinting to produce the imitation of skins of animals, and other effects. 125. Brussels Carpets. — Figuring with colour upon pile fabrics involves a different arrangement of the structure and also of the pile threads, unless the pattern is printed. We might take as an illustration Brussels carpets, in which well-defined patterns are formed by a variety of colour, and see what is the principle of structure, and how far it will apply to others. The pile itself is formed exactly the same as in ordinary or terry velvet — namely, by the insertion of wires under the pile threads — but the process of selection of the threads is different. In weaving ordinary velvet we bring either the whole or half the pile warp to the surface over each wire, but in Brussels carpet we may be said to have a Fig. Iji. series of duplicate ends, each of a different colour, and from these we select one, according to the pattern we require. Again, in ordinary velvet the pile warp inter- veaves into the ground just the same as the ground warp, except at the point where pile is formed ; but in Brussels carpet it does not, but is contained as a straight thread in the body of the cloth when not forming pile. Take the section Fig. 104 ; the ground warp is represented by the lines a, and the weft by the dots, the three colours of warp by b, c, and d. Now the ground cloth is plain in one sense. If the ground warp threads be separated from the pile warp, and considered only in relation to 222 DESIGN IN TEXTILE FABRICS. [Chap. VIII. the weft, they will form a plain cloth with two picks in each shed, but taken as they stand, the ground picks are separated by the pile warp. In fact, the pile warp is held between the ground weft, and intersected by the ground warp, so that if no pile or loops were to be formed, we should have a plain cloth with a stout packing in the middle, the packing threads being perfectly straight, and taking no part in the formation of the cloth, except to give bulk to it. Between every pair of ground warp threads there is one thread of each colour of pile warp which is to be employed. Then, for the formation of the pattern, one of each of these sets of pile threads is raised between each pair of ground picks and passed over a wire, it then returns to the cloth, and if required to form the next loop is again raised, and so on, until its own portion of the figure is completed, when it remains in the cloth until again wanted to form figure. In the same maimer the pile threads are treated ; they are lifted over the wire to form a loop whenever the arrangement of the pattern calls for their presence on the surface, and as soon as that portion of the pattern is completed they return to the cloth, and continue to form the body. From this it will be seen that although there may be three, four, five, or six colours, and consequently as many separate pile threads between each pair of ground threads, only one of each set is brought to the surface at once, so that there is always the same quantity of pile on the surface, and the same substance in the body of the cloth, no matter what the pattern may be, or how frequently the pattern changes from one colour to another. Then the advantages of this mode of structure are that we have uniform surface and body of cloth ; and we have pattern formed by colour only, and any amount of variety in the pattern will not afiect the structure or quality of the cloth. The pattern being formed by difierently coloured threads coming to the surface in suc- cession, is very clear and well defined, and the whole of the pile material being embedded in the body of the cloth Cliap. VIII.] TAPESTRY CARPETS. 223 makes the fabric both bulky and soft. One peculiar advantage, from the useful point of view, which Brussels carpets possess, is that each thread which comes to the sui'face to form a loop, being only one of a number, is well embedded with the rest in the body of the cloth, so that when the foot is placed upon it, it is pressed into a naturally elastic body of material, which serves as a cushion for it, enabling it to give way under the pressure of the foot, and also by its elasticity to spring back to the original position, thus reducing the wear and tear con- siderably. 126. Tapestry Carpets. — Another class of carpets which are made to imitate Brussels are known as tapestries. The structure of the cloth presents some- what the appearance of Brussels, but instead of there being a number of threads together of different colours between each pair of ground threads there is only one, and that is printed so as to form the pattern. In fact, each pile thread is printed in colours according to the pattern to be formed, proper regard being paid in the process of printing to the length of warp which will be required to form the loop, and also for bending round the weft. Then they are put together in the warp in their proper order, and, as we have said, woven after the manner of Brussels carpet, but one printed thread serving for a number of coloured ones. This is a most economical method of producing figured carpets, but of necessity does not produce so serviceable an article as that which it imitates. There is no substance in the body, except what is known as the backing, and as this consists of stout linen, there is not the same elasticity as in the worsted body of Brussels carpet, and therefore not the same tendency to reduce wear and tear. The structure of the Wilton carpets is similar to thab of Brussels, but the pile is cut, or practically the difference is the same as that between cut and terry velvet. 127. The Varieties and Properties of Plushes. — We have now enumerated the principal kinds of plush or pile 224 DESIGN IN TEXTILE FABRICS. [Chap. VIII. whicli are made. There are many modifications of these in use, in the production of difierent kinds of fabric for different purposes, but these are modifications of miiior details generally : the principle of structure is not alFected by them. There are numbers of patent, plushes, all claiming some advantage over others, but still, the improvement is usually in some trifling alteration of binding or distribution, or perhaps more frequently in the method of production, but the general principles we have referred to cannot be far departed from without impairing the structure of the cloth, or even if that is not actually done, there can be little advantage gained. One very economical method of making velvets, which has been attempted over and over again with varying degrees of success, has been within recent years brought to something like a state of perfection — namely, weaving two cloths together, and the pile passing from one to the other; they are then severed in such a manner as to leave a proper proportion of pile upon each cloth, thus dispensing with the use of wires, and consequently reducing the cost of production very materially. But even in this, the principle of structure of each cloth remains practically the same as if they were woven with wires ; it is only a modification of the means by which the article is manu- factured. With respect to the utility of pile fabrics, little need be said more than we have already pointed out. From the nature of the surface, as well as the structure of the body of the cloth, they must necessarily form very warm articles of clothing, the closeness of texture and the intermixing of the loose fibres of the pile all tending to assist in retaining warmth. They are also soft and pleasant to the touch, and altogether pleasing as articles of dress or furniture ; one remarkable feature to which we have already referred being the richness of colour, and the variety of light and shade which they present, more especially when arranged in folds, the undu- lations placing the loose fibres in so many different positions to reflect the light, and this variety of reflections Chap. IX,] GENERAL COMPARISOIT OP FABRICS. 225 giving richness and variety to the colour and lustre of the whole fabric. In their wearing properties plushes are also very vahiable, there being scarcely any fabric of the same weight which will prove more durable, so that they combine all the properties which go to make cloths valuable — richness and beauty with utility. CHAPTER IX. GENERAL COMPARISON OF THE DIFFERENT CLASSES AND STYLES OF FABRIC. 128. The Considerations involved in the Structure of Fabrics. — We have dealt pretty fully with the different principles of structure of fabrics and their ornamentation ; and it will perhaps be desirable now to examine a little more fully some of the considerations involved in their structure, to make a comparison of the different classes and styles of fabric, and also to deal with some forms of ornamentation which we have not touched upon, and the special method of their application. "We may first recapitulate generally some of the points discussed in the earlier chapters, so that we may take a more comprehensive view of the whole. Dividing, for the moment, all fabrics into two distinct classes, without entering into their particular structure, we may say that the one is intended for useful and the other for ornamental purposes. Taking the purely useful, we have the question of strength before us, the necessity of the fabric being able to bear strain, or friction, or both ; . then we have to regard it as an article of clothing, its power of retaining the warmth of the body, or of resisting climatic influeuces. In the first case one of two con- p 226 DESIGN IN TEXTILE FABRICS. siderations comes in; either we must have a strong, compact, well - formed thread, of which to form the cloth, or the threads must be so interlocked with each other as to make the whole fabric as it were one solid mass. If the threads are of such a nature that all the fibres of which they are composed are spun intimately together, foi-ming a smooth- surfaced, even filament, then they will stand separate from each other in the fabric, and its entire strength will consist of the multiplication of so many units ; and if the cloth is to bear a great strain, more especially if this strain is likely to be localised, either each individual thread must bo very strong, or strength must be obtained by having a great number in a small space. The strength of individual threads may be obtained in two ways : either by having it constructed of fibres of great strength, or by having the fibres well twisted together. Combined with the strength of the thread, the order of interweaving of the two sets of threads of which the cloth is composed must be taken into account, and, as we have shown of ordinary fabrics, the plain cloth, or that in which the two sets of threads interweave alternately, is the strongest for the quantity of material which it contains (we are leaving gauze out of the qiTCstion, as being an ornamental fabric). If the capacity of the fabric to bear strain is to be in one direction rather than another, as in the warp or weft, then that material must predominate, and we arrive at the class of cloth showing a rib in one direction or the other. We have here, then, the general considerations of strength immediately before us, and although we have spoken only of plain cloth, the remarks will apply equally to twilled or other fabrics, in which we have resorted to a different order of interweaving, either for the pui'pose of obtaining greater weight or for ornamentation. In cloths formed of the kind of thread we have spoken of there will be openness of texture, and the size of the openings between the threads will be in the direct ratio to the diameters of the threads in a Chap. IX.] GENEBAL COMPARISON OF FABRICS. 227 clotli where warp and weft are equal in quantity. Thus, to obtain closeness we must increase the quantity of either warp or weft. To do that is to increase the weight. Now, if our cloth is to be a light one, and we wish it to be still of a close texture, we may obtain it to some extent by altering the structure of the thread. Instead of having a smooth, even thread, we may have a considerable amount of loose fibre on the surface ; these loose fibres will help to cover the interstices, and in the process of finishing, if the fibres of one thread be made to interlock with those of other threads, the compactness of the fabric will be increased. But this is not all ; the interlocking of fibres gives additional strength. Not only do the warp threads support each other, but the weft threads interlock with them, and the whole fabric becomes more compact, not merely as far as closeness of texture is concerned, but as regards tensile strength^ and also the power to resist friction. Thus we have here a very intimate relation between the structure of the thread and the strength of the fabric, as well as its closeness of texture ; so that it is evident the character of the thread is an item we cannot afibrd to ignore in determining the structure of the cloth. Apart from the question of material or structure of thread, we must now consider how these conditions can be obtained in the structure of the cloth only. If we resort to twilling — that structure which most nearly ap- proaches to plain cloth — we obtain in the first place greater closeness of texture than in an ordinary plain fabric, because of the necessity for introducing a greater number of threads, to compensate for the looser order of interweaving. We obtain also greater strength for the same reason, and also of course increased bulk. Then, again, this increase may be in the weft, in the warp, or both, according to the character of the twill we employ. If we take satin cloths — one form of twilling — we obtain all we require in strength and closeness of texture in one direction only — that is, by an increase of 228 DESIGN IN TEXTILE FABRICS. [Chap. IX. either warp or weft, in number of ends or in thickness, more generally by the increase of ends. Our next alter- native is a resort to double cloths, which gives us the means of increasing weight, strength, or closeness of texture to any degree. Then we have here, in the struc- ture of the threads, and the structure of the fabric, in simple form, all that we require to enable us to make the cloth fulfil all the conditions of usefulness. 129. Ornamentation of Fabrics by the Use of Colour. — Now with respect to ornamental fabrics. As we have shown, we may ornament with colours, with patterns formed upon the fabric, or in the structure of the fabric itself. We will first turn our attention to the question of ornamenting with colours, not with a view to dealing with the theory of colour in general — that has been already done many times in works on decorative art, including, of course, textile fabrics, in a much more complete manner than could possibly be attempted here — but to consider it in its connection with structure of the fabric, and see what will afiect or interfere with its use, and how far this interference may necessitate the ornamentation assuming some particular form or character. It has been pointed out in a previous chapter that the ornamentation of plain cloth must be by the use of colour, or by the predominance of either warp or weft, so as to produce cords running the length of the piece or across it ; but this predominance of one of the materials will also affect the use of colour. When weft and warp are equal in plain cloth, we may introduce coloured threads into either one or the other with a fair chance of their being visible on the surface. Then we may form either stripes or checks, just as we use coloured threads in the weft or warp, or both ; and the variation in those threads, in both colour and quantity, will give us great scope for the display of ingenuity and taste. True, the patterns always run in straight lines, yet they may be made both pretty and efl'ective by proper regard being Chap. IX.] ORNAMENTING WITH COLOURS. 229 paid to variety of line and colour. But it is only when warp and weft are equal, or nearly equal, that we may use colour in both warp and weft at will. We will sup- pose, for example, that the warp is predominating very largely, that the number of ends per inch greatly exceeds the number of picks ; then the weft will be completely hid, and whatever colour it might be it would not be seen on the surface of the cloth ; so that in such a case we are precluded from using variety of colours of weft, and consequently, the cloth being plain in structure, we can only apply colour to form stripes running in the direction of the warp, seeing that the only coloured ends which can be visible must be in the warp. On the other hand, if we are making a corded cloth, with the cord formed in the warp, then the weft would predominate largely in quantity, though not necessarily in the thick- ness of the threads ; but the closeness of the weft picks would completely cover the warp, so that whatever might be the colour of the warp, it would not be seen, at least not sufficiently to permit of a pattern of coloured ends being formed by it. So that whether the warp or weft predominate, we can only use colour in that portion of the fabric. Precisely the same rule will apply to twilled or satin cloths, and perhaps even in a more marked degree than in the majority of plain cloths. In either twill or satin cloths, where the warp or weft is brought much to the surface, it also predominates largely in actual quantity also ; so that the other material is thrown abso- lutely to the back of the fabric, and is not seen at all on the face. Thus we can ornament only in the direction of the threads which are on the face, and we are there- fore necessarily confined to stripes. Although we cannot form anything but stripes by the use of colour in fabrics where either warp or weft pre- dominates on the face, and when we confine ourselves to the material which forms the ground or body of the cloth, yet we are not preckided from the use of extra weft or warp to form checks. But of course the cloth will cease 230 DESIGN IN TEXTILE FABRICS. [Chap. IX, to be purely plain, twill, or satin, as the case may be. We will take as an extreme instance a cloth, say such as a repp, in which the warp predominates very largely, and introduce coloured threads in the warp; these colours will stand out very prominently, because the modification usually produced by interweaving with the weft is not pre- sent here, the weft being so completely hid. Then if we wish to form a check upon this, our coloured weft must not interweave with the warp in the usual manner, or it will be lost, but it must be thrown to the surface of the cloth, and interweave with the warp threads only at intervals. In fact, it must form either a twill or satin with the weft predominating, and by this means and this only we may form our checks as distinctly as we please. If it is a cloth in which the weft forms the surface, then the coloured extra threads must be in the warp. In forming figures upon such cloths as we are speaking of, the use of colour is most effective. Suppose the warp is a light colour and the weft a dark one, and that a figure is formed by bringing the weft to the surface, the warp preponderating on the surface all over the ground ; in the ground the colour of the warp only will be seen, the weft being hid, and in the figure the weft only will be seen, so that the pattern will stand out very prominently. If the colours be properly suited to each other, so as to form an harmonious contrast, the effect will be most striking. Then in using colour for the ornamentation of fabrics when the coloured threads form part of the groundwork of the cloth, it is evident we must take into account the structure of the fabric, and only use the colour in such manner as will be effective. When we are using extra colour or coloured threads for the sole purpose of ornamentation the conditions are quite different — whether we use them in the weft, in the warp, or in both — from those which exist when the coloured threads form the ground fabric ; when they are extra threads we may treat them as we please, bring them to the surface in long Chap. IX.] THREADS OF MIXED COLOURS. 231 or sliort i^eriods, or bind them into the cloth, so as to intermix the colour with the colour of the ground threads, and so modify their effect. In short, we employ them for decorative purposes only, and need to use proper discretion in their disposal, so as to produce the effect desired, with little or no regard to the structure of the ground fabric, except such as has been previously pointed out. 130. The Use of Threads of mixed Colours.— In speaking of coloured threads we generally mean threads which are one colour throughout, but we are not necessarily confined to coloured threads of this descrip- tion in ornamenting fabrics. We may twist two differently coloured threads together, and so produce a parti-coloured one, known in the trade as " grandereile or we mix fibres of different colours together, m the preparation of the material for spinning, and so produce " mixture " yarn ; or we may have the fibres of which the thread is to be composed printed in one of the inter- mediate stages of preparation, and so produce the "melange" yarn; or we may have the threads printed. From such fancy yarns as these we may obtain very pretty effects upon fabrics which may be perfectly plain in their structure; or if a pattern is formed in the fabric, it may be of the simplest kind. The whole effect may be a mixture, or melange. We may introduce the twisted, coloured, or printed threads into otherwise solid coloured fabrics, or coloured threads into mixture fabrics. These extra threads, as we may term them, may either form part of the ground cloth or interweave simply as ornamenting threads, according to the kind of effect to be produced, whether it is to be of a mild, tame character or a striking one. In fact, we have a wide field thrown open for the exercise of ingenuity in the use of these fancy threads. The use of "mixture" or "melange" threads generally is for the production of a tertiary coloured effect upon the fabric with very small patches of strong local colour; and if several striking colours are introduced into the mixture it does this in the most 232 DESIGN IN TEXTILE FABRICS. [Chap. IX. effective manner. The intimate mixture of the fibres in the yarn will, when woven into the cloth, insure to the utmost the tertiary effect being procured, while on moderately close observation the local colours will assert themselves, and even at a distance will give a bricrht sharp freshness to the whole. ^ ' In cloths where no specially striking effect is intended, the best means of ornamentation and of producin^r prettiest effects is by the use of "mixture " threads 131. Fancy Yarns in Fabrics.— In addition to fancy yarns composed of differently coloured fibres, or by the twisting of differently coloured threads, many very good efiects are obtained by twisting two threads together of the same or different colours, at different degrees of tension, so that one wraps loosely round the other— say, for instance, a thick thread twisting more or less loosely round a fine one— and presents to the eye a kind of crimped effect; this, when woven into the fabric, if judiciously used will be very pretty Again, loops may be formed upon the thread by one thread running in loosely during the process of twisting while the other is held tight, or one thread may be given off at a regular rate of speed, while the other is varied m speed, so producing not only different thick- nesses of thread, but, if the two threads are of different colours, different coloured effects. All these give us powers of ornamentation merely by their introduction into an ordinary fabric. We now come to the question ot the ornamentation of fabrics in their structure and we will consider it first apart from the question oi utility. ^ 132. Ornamentation of Fabrics in their Structure —in plain cloths we can form patterns in one way only —namely, by the formation of ribs, which may run either lengthwise or crosswise in the piece ; these ribs we may vary m size, or place at varying distances, but we have no further power of ornamentation. In ordinary twill cloths we have similar ribs running diagonally Chap, IX.] ORNAMENTING WITH FIGURES. across the fabric, which we may vary in size and distance apart, but unquestionably we obtain the best effects when we either combine these diagonal ribs with small figures, or simply run small figures in a diagonal direction. There is no field so wide for obtaining different patterns in the structure of the cloth as in the combination of diagonal lines and figures. The variety of lines, heavy and light, and the combination of forms give us a power of ornamentation which is not to be exceeded by any other method where we do not call in the aid of colour. There is no branch' of the subject which should be more carefully studied by the textile designer, especially where his province is as much the designing of fabrics as of patterns. Next we come to the formation of figures by the ground weft, warp, or both — that is, by the material which forms the ground fabric ceasing to interweave, and so forming pattern by the weft, or warp, or both, lying loosely on the surface. By this mode of figuring we can produce any variety of form in the figures, and, by proper regard to the order of binding or inter- weaving, ornament the fabric to any extent, the only limitation being a due regard for the structure of the fabric. Then we have figuring with extra material, which again gives us the power of introducing additional colours, as well as the formation of distinct patterns on the surface ; so that our power of forming patterns is extended beyond that when the figures are formed by the ground material alone, and if we combine the two methods we have a still further extended power. In fact, the extent and elaborateness of our designs are without ' limit, and may fairly be likened to the use of colour and brush. Figuring with double cloths may perhaps best be compared with the use of extra material, as we have not only a figure of one colour upon a ground of a totally different colour, each formed by different materials, but any amount of figuring may be introduced without aflecting the structure of the cloth, and moreover, the 234 DESIGN IN TEXTILE PABEICS. [Chap. IX. fabric is reversible and may be used on either side. The advantage of figuring with double cloth, apart from the question of utility, is that the figure is perfectly solid in colour, upon a ground equally solid. Gauze, net, and lace are forms of ornamentation quite difi'erent from all other classes of fabric, and for lightness and elegance of fabric, as well as for the variety which may be introduced into the design, far exceed all others. Gauze is perhaps the most simple, and in the forms in which it is now generally made is probably the easiest of production ; at any rate, it possesses one advantage over both the others — it can be combined with ordinary woven fabric, either for the purpose of varying the design, or for ornamenting a cloth of closer or heavier texture. The other two will give a greater degree of openness and lightness. Plush ornamentation is peculiar to itself; it may be made to form simple figures, or the pattern may be in the plush itself. In what are commonly known as velvets — that is, where the pile is very short — ^the ornamentation is usually confined to the use of colour, in stripe or check form, or the formation of figures by the pile ; but in what are commonly termed plushes, where the pile is longer, the ornamentation more generally takes the form of making the pattern in the plush itself, either by waving, crimping, or varying the length of the pile, or some such expedient. We have used the terms velvet and plush here in the popular sense, not with the in- tention of making a distinction between the two, for they may be taken as being practically synonymous, so far as the manufacture of such articles is concerned. 133. Ornamentation by different Tension of the Threads, etc. — In addition to the methods of ornamenta- tion we have referred to, there are many others which can scarcely be called regular, but are the result of some freak or fancy on the part of the designer or manufac- turer — such, for instance, as the introduction of slack or tight ends in the warp, either singly or in numbers. Chap. rX.l THREADS OF DIFFERENT TENSION. 235 Suppose we allow a single end at intervals to run into the cloth much slacker than the rest of the warp ; it will crimp all along as the cloth is formed, and if it be a different colour from the body of the cloth, it will assert itself very strongly and produce quite a novel effect. Again, if a number of these threads have different degrees of tension, and of different colours, the effect will be still more novel. Another use of tight and slack ends is to form crimped stripes. Suppose one portion of the cloth is woven quite plain, and the rest twilled, or satin, the two running side by side in stripe form :— the twill or satin, if not very much more closely set in the reed, will permit much more weft being inserted than the plain ; then if the warp threads come off separate beams, one for the satin and the other for the plain, and the latter is allowed to go in quite slack, the weft as it is beaten in will carry the plain cloth forward, while the satin portion is quite straight, and so cause regular crimps or waves in the plain portion. These crimps may be increased or decreased, made more or less prominent by varying the setting of the warp threads in the plain or satin portions, or by varying the tension at which the warp threads are held. 134. Utility combined with Ornament.— We may now consider the question of utility combined with ornamentation, or, in other words, in all the various forms of ornamentation with which we have dealt, examine into their effects upon the fabric, and see how far they will affect its utility. Beginning again with plain cloth, as we have shown, when warp and weft are equal, there is no ornamentation except by the use of colour ; but we have a strong useful fabric, not heavy, except so far as the thickness of the threads of which it is composed makes it heavy, and not of a close or com- pact texture, owing to the order of interweaving of its threads, but yet strong and useful for the quantity of mate- rial which it contains. If we ornament it in its struc- ture, it must be by the alteration of the relative quantities 236 DESIGN IN TEXTILE FABRICS. [Chap. IX. and thickness of the warp and weft ; and in doing so we increase closeness of texture, generally also bulk and weight of fabric. By increased closeness we obtain necessarily increased strength ; for although each unit of strength, as represented by any single thread, may be less than in an ordinary plain cloth, the combination of these units will give greater strength to the whole. So that by ornamentation we increase usefulness both in wearing properties and in the power of retaining warmth as an article of clothing. When we ornament by twilling, we again obtain practically the same results — namely, increased weight, strength, and closeness of texture. The order of inter- weaving of necessity produces these results, but in different degrees, by the different kinds of twilling ; so that it becomes necessary for the designer in making his pattern to consider thoroughly its effect upon the fabric, and the kind of fabric he desires to produce ; and the relative quantities of warp and weft must be carefully- proportioned to the design of the twill. When we come to figuring with the material which forms the ground fabric — that is, when the fabric is of a given structure, and a figure formed by the weft and warp ceasing to interweave, and one coming to the surface as loose material — whatever may be the structure of the ground cloth, the formation of the figure must in some degree detract from it. If the ground is plain, we shall have a firm texture, though perhaps somewhat open; but when figure is formed, we have positively no texture, simply so much loose material ; in that case the useful- ness of the fabric is decreased, and just in the ratio of the amount of figures introduced. If the figures be small and closely set together, the texture of the cloth as a whole will be looser ; if they be large, then it will give extreme looseness in the figured portion, and will not much affect the ground, which will be in proportionately large patches ; but the cloth will be very irregular in texture, and this of itself is a serious drawback. Then, Chap. IX.] UTILITY WITH ORNAMENT. 237 for useful purposes, the small figures, equally distributed, are preferable ; for if the texture be very much loosened, we may to some extent compensate for it by the intro- duction of more material, either in warp or weft, or both, and treating it somewhat as we should treat a twilled cloth. Whatever applies to figures upon plain cloth also applies equally to figures upon any other ground, when the figure is formed by loose material. If our figures are formed upon the principle of diapers or damasks— that is, by the warp and weft merely changing places, and still preserving the same order of interweaving— then our figures may be as large or as frequent as we please, without in any degree im- pairing the utility of the fabric. When we introduce extra materials for the formation of figures, we in no degree afiect the ground cloth, either for better or worse ; it is merely applying so much colour to the surface, adding certainly to the bulk of the fabric at that point, but not necessarily increasing its usefulness, the extra material being in most cases simply laid loosely on the surface, so that it possesses no special wearing qualities, and will not add materially to the powers of the cloth for keeping warm. Of course we are speaking of the formation of spot figures by extra material. If the extra weft or warp be distributed over the whole area of the fabric, then it becomes a different thing; especially if it be bound into the cloth at the back, for it will then form a kind of double cloth, and often really two distinct fabrics. Of course in such cases we add to the fabric in every way ; we in- crease bulk, strength, and closeness of_ texture, and have a better wearing and a warmer article, as well as ODB more ornamented. Double cloths should always be treated under two distinct heads— first, when one of the cloths forms merely a Uning ; and second, where the two cloths exchange places to form patterns. The former may include all cloths where either two warps and two wefts, or where one warp and two wefts are used, if 238 DESIGN IN TEXTILE FABRICS. [Chap. IX. one surface be different to the other in texture and in pattern, and where one is intended for the wearing surface and the other merely as a lining. The second should include all cloths which are reversible— that is, which are wearable on either side, or in which either side may be made the face— whether there are two distinct cloths, or merely two faces formed either by two wefts and one warp, or two warps and one weft. In the first class will be included all fabrics which have a fancy face and a plain back, and which for wearing purposes are extremely useful. The texture of the face is usually fine, and ornamented according to the purpose to which It IS to be applied, possessing generally all the qualities ot useful fabrics. The back is of a more or less plain character according to the weight to be obtained, or it may be governed by the pattern and texture of the face, so that they may bear a proper relation to each other, Its chief purpose being to give weight, strength, and warmth. In producing heavy cloths, as those re- quired for overcoats, this principle is absolutely neces- sary, because the proper weight and texture of cloth could not be obtained in a single cloth. If we obtained weight it would be at the cost of fineness, and fineness would be obtained at the cost of weight ; but by the combination of two cloths, or two surfaces, we can comply with both requirements at once. When the cloth is reversible, both fabrics or both sides of the same fabric are equal in quality and texture though perhaps different in colour. Each surface may remain the same throughout, or they may exchange places. Their exchanging places is merely for the purpose of forming patterns; it will not affect the structure or utility of the fabric as a whole. If the fabric consist of two separate cloths these will exchange places bodily, each preserving its own individuality they continue to weave weft with warp in each cloth as though no exchange had taken place. If it consist simply of two wefts and one warp, or two warps and Chap. IX.] UTILITY WITH ORNAMENT. 239 one weft, the wefts or the warps only exchange places ; but on whichever side of the fabric they are weaving, they still preserve the same order of interweaving weft with warp. In fact, it may be said to be a double diaper, or damask, inasmuch as weft and warp always bear the same relations to each other in their orders of inter- weaving, whichever may be uppermost, so that whether figured or plain, the utility of the fabric is not impaired in the slightest degree. "With respect to gauze fabrics we need not say much as to their utility ; they are essentially fancy or ornamental cloths. Strength they may possess, but for warmth and general wear they are not specially suited, so that we need only regard them, except under exceptional circumstances, from a decora- tive point of view, and if we should have to consider them for purposes of utility, it will be in combination with other orders of working, and the conditions which apply to other fabrics will also apply to them. Plushes are essentially useful fabrics, as well as heavy ones, and in ornamenting them we very rarely impair their utility, except in the slightest possible degree. The body of the cloth must at all times be a very strong, compact structure, so as to hold the pile with sufficient firmness; and whatever ornamentation is introduced either with or in addition to the pile, or whatever is done with the pile, will not much impair the structure of the body. The wearing surface may be more or less affected, but that is not generally a serious matter, but the body of the cloth wUl never be much affected. This is equally true of both weft and warp pile. When we ornament with coloux'ed threads we do not afiect the utility ; the structure is not altered. We determine the structure of the cloth to suit it for the purpose to which it is to be applied, and then vary the colours of the threads of which it is composed, so that we first say.-jvhat the cloth shall be.^ajnd then how it shall be oriig,n{£?»tQd \S>it3): ddout-J^.ind^ll'iife^^h'^ have to consider, .th^ Hn'^ja'PEi^yi^^ 24G DESIGN IN TEXTILE FABRICS, [Chap. IX. yet the colour cannot affect the structure nor its utility as a fabric. If we ornament by varying the degrees of tension of the threads, then we do impair the struc- ture, for any strain thrown upon the cloth will be thrown upon the threads which are tight, and as they are only a portion of the whole, they cannot be expected to bear as much strain without fracture as if the strain were equally distributed over the whole fabric. Consequently fabrics of this kind must be made for purely ornamental pur- poses, and never considered as articles of utility, unless the slack threads are very few indeed. 135. The Special Knowledge required in the Manu- facture of Fabrics,— We may now understand the special knowledge required in the manufacture of textile fabrics, and upon what it is dependent. We have first to consider the nature of fabrics, and the uses to which they are to be applied. Having determined what we require, the character of the fibre from which the fabric is to be made, and the structure of the thread, we must next enter fully into the question of the structure of the cloth, considering it first from the useful point of view, then from the ornamental, or from a combination of the two. In any case thorough mastery of the different structures, of the various modes of ornamenting in tlie structure, and also of the effect of ornament upon structure, so as to know the extent to which utility will be impaired or increased by the particular method of ornamenting, is absolutely necessary. Given all this, along with knowledge of the mechanical operations of weaving and also of decorative art, and the designer possesses all the materials for the successful following of his vocation ; he will only further require those qualities which are essential in every walk in life — energy, perse- verance, and a right application of his industry and knowledge. GLOSSARY. Angle of Twill. — The angle which a twill forms with the weft or warp. Backed Cloths. — Cloths having a back woven upon them which serves as a lining. Beams, —Rollers upon which the warp threads are wound side by side before being -put in the loom. There are also cloth beams upon which the cloth is wound as it is formed. Binding in Cloths. — The securing together in the process of weaving two separate cloths, or extra material used for figuring or other purposes on an ordinary single cloth. Bobtoin-Net. — An open perforated fabric formed by a series of threads crossing and partially twisting round each other. Checks. — Patterns which are usually formed by coloured threads crossing each other at right angles. Chenille. — A thread having loose fibres projecting from it. Choking the Shed. — "When the warp threads are so numerous, or of so rough character that they will not pass through between each other, and separate readily into two portions between which the shuttle may pass. Cockling. — When the cloth, instead of presenting a smooth, even surface, is irregular, some portions standing up in bubbles. Cords. — Cloths with ribs which run longitudinally, or in the direc- tion of the length of the fabric. Corduroys. — Cords formed with cut pile. Crammed Stripes.— Striped fabrics in which one portion contains more warp threads in a given space than another portion. Cutting Plush. — Severing the threads which are to form the " pile " or surface of the fabric. Damask. — A cloth said to be named from the city of Damascus, formerly made of silk, but now of worsted or linen chiefly. Q 242 DESIGN IN TEXTILE FABRICS. Density of Pile.— The closeness with which the threads of velvet or plush are set together. Diagonals. — Patterns arranged to run in a diagonal direction across the fabric. Diaper. — A cloth similar to damask, but with the pattern of a " chequered " character. Double Cloths. — Two separate fabrics woven and fastened together in the process of weaving. Doups. — A special arrangement of healds used for gauze weaving, and so arranged that they may cause the warp threads to cross each other. Elong'ated Twills. — Twills which do not run across the fabric at an angle of forty-five degrees. Extra Warp or Weft Figures.— Figures formed upon a fabric by material which takes no part in the formation of the body of the cloth. Figured Cloths. — Fabrics having a pattern formed upon them by the order of interweaving of the weft and warp of which they ai-e com- posed. Figured Twills.— Figures running diagonally across the fabric. Floats. — Where the weft and warp of which a fabric is composed do not interweave with each other. Sometimes patterns are formed by " floats " only, and sometimes " floats " are formed accidentally in the process of weaving, and produce imperfection. Flushing is sometimes used in the sense of "floats." Fraying. — One set of threads slipping upon the other, and so pro- ducing imperfections in the fabric. Gauze. — A light perforated fabric in which the warp threads are made to twist more or less round each other. Healds. — An arrangement for effecting the separation of the warp threads, so that the shuttle carrying the weft can be passed between them. The he ild consists of a series of cords having an eye in the centre, and attached at each extremity to a flat piece of wood, called the "heald shaft," the warp thread being passed through the eye of the heald. Whenever the heald shaft is raised or depressed the warp threads are also raised or depressed, and so the warp is separated into two portions for the shuttle to pass between. Jacquard Machine. — An apparatus for separating the warp threads in a similar manner to healds but on a more extended scale, and con- sequently facilitating the production of elaborate patterns. GLOSSARY. 243 Lace.— An open perforated fabric produccxl by the threads of which it is composed being twisted together in such a manner as to form patterns. . Lappet Figuring.— Figures or patterns produced on a fabric by a warp thread being made to cross and recross on its surface by means of a "lappet frame." Madras Muslin, or sometimes called Indian Muslin.— A light fabric figured by the insertion of thick weft threads, which are cut away where there is to be no figure. Net.— A fabric formed in a manner somewhat similar to lace, but having its perforation equal. Pile.— The threads which issue from and form the surface of fabrics such as velvets. Plain Cloth.— A fabric in which the warp and weft threads are placed at right angles to each other, and which interweave alternately. PIusH.— A fabric the surface of which is covered by short threads which issue from the body of the cloth. Repps.— Fabrics ribbed across the piece. Sham Plush.— An imitation of a plush fabric produced by using Chenille weft. Sometimes sham plushes are made by " raising "—that is, dragging— the fibres partly out of a cloth of ordinary loosely con- structed fabrics. Shed.— When the warp threads are separated for the shuttle to pass through. Shuttle. — A small apparatus for carrying the weft, and which is passed to and fro through the warp. Swivel Shuttles.— An arrangement of small shuttles for forming figures on a fabric, somewhat after the manner of embroidery. Tabby. — A name commonly applied to plain cloth. TwlU. — A pattern running diagonally across the fabric. Velvet. — A short or closely shorn plush. Warp.— The threads which run lengthwise in a fabric );(^eft.— The threads which run crosswise in a fabric. Yam.— The thieads of which a fabric is composed. INDEX.
