PATENT OFFICE SANFORD L, GLUETT, 0F TROY, NEW YORK, ASSIGNOB TO GL'UETT, PEATBODY .& 00., INC., 01 TROY, NEW YORK, A CORPORATION OF NEW YORK ART OF MAKING TEXTILES AND 'I'E XTTLE ARTICLES Application filed August 2, 1928. Serial No. 296,976.
This invention pertains to the treatment of textile fabrics, to a fabric so treated, and to articles made therefrom, and has for its prin.
cipal object the productionof a fabric or article which is' substantially non-shrinkable in one direction at least, for example in the direction of its constituent weft threads, but which at the same time possesses the lustrous and pleasing appearance resulting from usual cloth finishin operations.
A preferred met 0d of obtainin the desired results comprises stretching t e fabric under heavy tension in the direction of one set of its constituent yarns (for example the wefts), being careful during said stretching not 'to'confine the fabric lengthwise (that is, not to interfere with its freedom to contract in the direction of the warp yarns), the operation, in the latter respect, being fundamentally unlike ordinary cloth stretching or .tentering. Concomitantly with the stretching, I may moisten or steam the material,
and subsequently dry it and/or iron it to set the yarns. The net result of this operation is to produce a fabric whose weft yarns are substantially straight while its warp yarns have a maximum crinkle. Consequently, the fabric is substantiall non-shrinkable in a 'warpwise direction w en subjected to subsepeatedly without substantial decrease in length or size.

\ For the manufacture of shirts, collars, at. it is usual to employ a fabric of a comparatively simple weave, such as a plain one-andone, a two-and-two, a three-and-one twill, etc. As an illustrative example of such material, plain one-and-one piece goods, as received by the garment maker, possesses the typical cross-sectional structure indicated in Fig. 5 and has a trade finish, (which, in cotlustrous glossy appearance) resulting from such usual cloth finishing processes as calendering, dressing, braking, ironing, etc. A weft yarn 2 and a warp yarn 3 raveled out from such a fabric will be found to ossess more or less the appearance shown in ig. 6, each of said yarns being wavy to approximately the same de ee If such a iece o material be sub'ected to. full laundering or fullin each set 0 its component yarns tends to ecrease in length so that the opposite edges of the fabric approach and the area 0 the fabric is reduced. After such shrinkage of the material, the weftand war yarns, when unraveled, have more or less t e a'p earance indicated at 2 and 3" respectively 1n Fig. 6", the yarns of both sets bein more abruptly crinkled than in the origina fabric. If the laundering or fulling operationbe carried to a suflicient extent, the crinkling of the yarns becomes so pronounced that little further shortening of the fabric in either direction can take place by reason of the close packing of the yarns and the elimination of interstices at the crossing points, but laundering or fulling substantially destroys the lustrous and pleasing appearance produced in the finishing operation so that materials thus shrunken are not desirable for use in juxtaposition to unshrunken materials in garments or the like.
In accordance with my present process I preferably select finished fabric of the desired character, for example a one-and-one fabric of the cotton broadcloth type having its weft yarns (Fig.' 2) spaced somewhat further apart than the warp yarns and having substantially the relative crinkle produced in the weaving operation. I now stretch this fabric under heavy tension in the direction of one of its constituent sets of yarns, for example in the direction of the filling or weft yarns, as indicated by the arrows 6 and 7 in Fig. 1, preferably moistening the fabric, as for example by steaming, prior to or concomitantly with this stretching operation.
An essential feature of my improved process resides in permitting the material, while thus being stretched weftwise, to move warpwise freely and without substantial restraint.
Since this stretching involves the application of transverse stress of sufficient intensity to shift one set of yarns relative to the other (as distinguished from the slight transverse 7 tensioning commonly applied by hand in feeding cloth to a mangle or the like), I prefer to employ appropriate power driven mechanism for the purpose. Doubtless various machines may be devised for accomplishing the result. For example, a special tentering frame might possibly be used in .which adjacent clamps or pins of each tenter- 'ing chain are free to approach longitudinally.
of the fabric as the transverse stretching proceeds, but I find means such-as illustrated in my copending application for Letters Patent Serial No. 332,919, filed January 16, 1929,
particularly desirable. In this latter device there is provided means for applying the fab-,
ric to the holding pins of a tentering chain in such a manner that between adjacent pins the material is initially slack so that longitudinal shrinkage is not interfered with.
As a result of this stretchin process, the weft yarns are pulled out near straight so that they substantially lose their normal crinkle, but in thus straightening, the weft yarns im ose astrain upon the'warp yarns, caus'in t e later to creep or crawl lengthwise and to ome deeply crinkled as indicated at 3 in Figs. 3 and 410 that the fabric shrinks in length and the end18 and 9 ap roach; If
this transverse stretching be en ciently intense or prolonged, each bend of the warp with this yarn will become of substantially semicircular extent, having asa center of curvature the center of the weft yarn over or under which it passes and when the warp arns have assumed this position, little furt er decrease in length can take place. verse tensioning stress to which the cloth is subjected in this stretchingoperation results in a permanent change in the character of the material, and-is not to be confused with such combined lateral and longitudinal tensioning as is incidental to tenterin mangling, folding, etc. whose primary 0 ject is merely ,to remove wrinkles and which produces no substantial or permanent change in the cloth structure. The original trade finish of the material is substantially unimpaired by this mechanical shrinkage and the shrunk-- en fabric may be used in juxtaposition to unshrunken fabric without showing any appreciable'difference in appearance.
The material takes a set in its new condition, particularly if moistened before stretching and allowed to dry thereafter, but to make the set more pronounced, I may subject the material to heat. I find that subjecting the shrunken material to the action of warm dry air while under slight tension, imparts the desired set, but I may subject it to an ironing operation as by passing it between heated rolls, or to any other desired treatment where by to cause it to retain with certainty the qualities imparted by the aforedescribed stretching operation.
Having thus prepared fabric possessing the surface appearance of goods as finished in the piece but whose constituent yarns are so disposed as to oppose decrease in length in the direction of one set of yarns, I lay out on this material the blanks which are to be used in the making of the selected garment. Thus, as indicated in Fig. 1, I have shown collar blanks 10 laid out longitudinally of the fabric since the length of a collar is the imortant dimension. Prior to shrinking the abric as above described, it is preferable experimentally to. determine the shrinkage of the normal fabric under the conditions of use for example in laundering, dyeing, stitching, etc., and then to pre-shrink it in accordance lprocess to an amount approximating such s rinkage of the normal fabric. If this procedure be followed, the blank may be cut to substantially the exact desired size,
since subsequent operations do not affect its length. If on the other hand the material be pre-shrunken in accordance with my process to a maximum possible extent, it may show a slight increase in length rather than a dccrease when laundered.
I next assemble the blanks in usual manner and seam them together to form a collar. "I have shown (Fig. 7) a collar havinga top comprising a face ply 11 which is formed of the material treated as above described and This purely transa neck-band 12 whose face 1y is also preferably of this material. he lining 13 or other elements. of the collar, not exposed to view may, if desired, be made of fabric shrunken by laundering or fulling, since the preservation of the trade finish u on such parts is immaterial. Those parts, or example the face ply of the to and neck-band, which are exposed to view, eing made of the fabric shrunken mechanically as above described, are substantially indistinguishable in surface appearance from the original fabric as finished in the iece, and thus althou h the collar produce by this method may e made of substantially the exact desired size and will not shrink longitudinally even after repeated washings, it initially exhibits its original trade finish so as to match other parts of the shirt, or other garment with which it may be associated or incorporated.
Although I have made specific reference to a collar and neck-band 'as the garment or part of a garment to be made from my improved material, I wish it to be understood that other portions of garments, for example shirt fronts and backs, sleeves, cuffs and the like, as well as any other garments, parts of garments, or in fact any article where unchanging length is desired when subjected to laundering or likeoperations, may well be made from the improved material.
\Vhile I prefer to proceed as above described in preparing my improved fabric, I contemplate that fabric having the desired characteristics, that is to say, having one set of yarns disposed in substantially straight extended condition and the other with a substantially maximum crinkle so that it can not shrink to a substantial degree in the dire: tion of the latter set, and having its original trade finish substantially undisturbed,,
