ASSOCIAE ATTORNEYS Patented Jan. 28, 1941 UNITED STATES PATENT OFFICE Application December 9, 1936, Serial No. 114,985 In Great Britain December 24, 1935 1 Claim.

This invention relates to improvements in textile fabrics and more particularly to multiple-ply fabrics as used in the production of semi-stiff collars, cuffs, fronts, pique vests and the like.

It has been proposed to produce multiple ply I fabrics in which two or more layers of cloth, or warps are united together by binding warp or weft threads or other forms of interweave to provide a multiple ply fabric.

It has also been proposed to form a multiple ply fabric by uniting a plurality of layers of cloth by means of intermediate layers of cloth having a proportion of their warp threads formed from cellulose acetate or by a blend of 1 two polyvinyl resins, rendered adhesive by heat or pressure, with or without the addition of latent solvent or combination of such, whereby the several layers of cloth are united into a multiple ply fabric.

Diiiiculty has been experienced in the employment of fabrics united together by the fusing of the intermediate layers of cloth owing to the various layers being liable to come apart during laundering or other processes and further in their use for collars the insertion of the collar top I into the collar band causes a very thick clumsy seam making a neat fold line-diflicult to obtain.

In addition collars, cuffs, fronts and the like which are made. frommultiple ply fabrics united 0 together by the fusing of intermediate layers have not the same wear-resisting properties of collars, cuffs, fronts and the like made from mulitilple ply fabrics united together by interweav- 5 According to the invention the fabric is constructed'from a plurality of plies of cloth connected together during weaving by binding warp or weft yarn or other forms of interweave in Y which a proportionof the warp or weft yarns 40 forming the weave or filling yarns intermediate the plies of cloth or warp, are thermoplastic being coated with or formed of a substance which on the application of heat or pressure with or without the use of a latent solvent will cause the 45 coating or thermoplastic yarn to be dispersed or fused and spread evenly throughout the fabric causing the latter to become permanently. stiffer.

' In one form of the invention a proportion of the warp :or weft yam employed is formed of or .50 coated with, any chemical solution to form a thermoplastic yarn or coating which after the .yarn is woven into the cloth, will on the application of heat or pressure with or without the addition of a suitable solvent or plasticiser cause the thermoplastic yarn or coating to be dispersed or fused evenly throughout the cloth to give it a permanent stiffness.

In a further form of the invention applied to a cloth or fabric having a plurality of layers of warps united together during weaving by bind- 5 ing warp or weft yarns passing from the front to the back of the cloth or fabric and in which filling warp yarns are inserted between adjacentlayers of warps i. e. yarns which merly lie straight between the layers without appearing m on either face of the cloth, all or a proportion of such filling yarns are formed of or coated with any chemical solution to form a thermoplastic yarn or coating which after the cloth or fabric has been woven will on the application of heat or pressure or a suitable solvent or plasticiser, cause the thermoplastic yarn or coating to be dispersed or fused evenly throughout the cloth or fabric to give it a permanent stiffness.

The invention is illustrated in the accompanying drawing in which:

Fig. 1 is a longitudinal section on the line ll of Fig. 2 of a fabric, on a greatly enlarged scale, employing a weft of cotton and a thermoplastic material inserted simultaneously.

Fig. 2 is a plan of the fabric shown in Fig. 1 with the lower warp yarns omitted for clearness of illustration.

Fig. 3 is a plan, partially broken away, of a fabric on a greatly enlarged scale employing cotton and thermoplastic filling warp yarns.

Fig. 4 is a'plan of a collar constructed with ,filling warp yarns a proportion of which are formed of thermoplastic material as shown in Fi 3. 1

The fabric shown in Figs. 1 and 2 comprises a two-ply fabric constructed with cotton face warps a in one ply woven in with a cotton weft ya'rn I and a thermoplastic. weft yarn I inserted si- 40 -multaneously and cotton face warps b in the other ply also woven in with a cotton weft yarn l and a thermoplastic weft yard 2 inserted simultaneously to provide a proportion of the weft yarns of a thermoplastic material which on the application of heat and pressure with or without the addition of a solvent or plasticizer will fuse to give additional stiffness to the fabric. The two plys are united together during weaving by binder warp yarns 3 interwoven with the weft yarns l and 2 of the two plies, the yarns 3 coming to both faces of the fabric on each pick 7 and preventing any separation of the plies.

The fabric shown in" Fig. 3 comprises a twoply fabric constructed with cotton face warps a tween the warp'yarnso and b and do not ap- V pear on either face of the cloth. The filling warp yarns B on the application of heat and pressure with or without the addition of a solvent or plasticizer will fuse to give additional stiffness to the fabric. The two layers of warp yarns a and b and the filling warp yarns A and B are united together during weaving bybindcr warp yarns 3 interwoven with the weft yarns I of the two layers, the yarns 3 coming to both surfaces of the fabric on each pick and preventing any separation of the plies.

The collar C shown in Fig. 4 is cut from the fabric shown in Fig.- 3, a portion of the binder warp yarns 3' being severed to allow the upper ply to be turnedback and the filling warp yarns A and B to be seen. The thermoplastic warp yarns B as shown have not yet been fused by the application of heat and pressure to stiffen the collar.

The chemical substance employed for forming the thermoplastic yarn or coating for the warp or weft or filling yarns capable of being fused or dispersed throughout the fabric by heat or pressure may be cellulose acetate or other cellulose derivative or a blend of two polyvinyl resins or other known substance having similar properties and may in, the case of cellulose acetate yarns, if necessary, before the application of the heat or pressure, he damped in known manner with acetone or other latent solvent of the thermoplastic yarns.

This multiple ply fabric is particularly applicable for use in the manufacture of semi-stiff collars which require to have a semi-stiff neckband and semi-stiff outer skirt or collar proper to the treatment so that the unprocessed yarns 15 remain undissolved and the collar readily folds along this line, or the thermoplastic yarns may be omitted along the fold lines.

The fabric is also applicable for use in the manufacture of semi stifl double cuffs, both the' under and the top portions of the cufl requiring to be stiff while the fold-over line is softer than the rest of the cufl. I

The fabric is also applicable for use in-the manufacture of shirt fronts or for pique vests.

In the case of collars which are made with semi-stiff collar skirt but separate'soft collar bands the portion of the collar skirt to be inserted into the band along with a sumcient allowance for the fold line is not processed, leav ing this portion softer than the rest of the collar, so that it will readily fold along this line.

What I claim as my invention and desire to protect by Letters Patent is:

A multiply fabric consisting of two plies of $5 I fabric woven together by binder yarns, a proportion of the binder yarns comprising thermo' plastic material which are fusible by theapplication of heat and pressure to increase the permanent stiffness of the material.
