Application July l?, 193i, Serial No. 553,52?

12 claims.. (ci. ias-dici This invention relates to improvements in woven fabric.

The primary object of this invention is the provision of an improved textile fabric which is prod vided with interwoven metallic threads, such as of copper, and which may be used for a variety of v purposes such as set forth in my co-pending application Serial No. 471,758, led July 30, 1930, and which embodies improvements thereover in i@ the provision of improved means for anchoring, interweaving and twisting the wires in the fabric. Other objects and advantages of this invention will be apparent during the course of the following detailed description.

In the accompanying drawing, forming a part of this specification, and wherein similar reference characters designate corresponding parts throughout the several views,

Figure 1 is a face view of the preferred form of improved fabric, showing the improved relation of interwoven warp and weft yarns. Figure 2 is a face view of a modified form of invention showing a fabric similar to Figure 1, but with a greater multiplicity of wire warp threads. In the drawing, wherein for the purpose of illustration are shown preferred and modified forms of the invention, the letters A and B may generally designate the preferred and modified forms of the improved textile fabric. In the preferred form 3G of fabric A, series of relatively twisted pairs of flexible wire warp threads are employed, the series being substantially parallel and appropriately spaced so that in connection with the filler or weft yarns interwoven therewith the finished fabric will present a gauzy appearance, such as leno. Each series of warp threads comprises a pair of iiexible wire strands 10 and 11 which are sinuously bent in the plane of the finished fabric, the strand 10 having the bends 12 therealong and the strand ail 11 having the bends 13 therealong vwhich are opposed to the bends 12; the facing bends 12 and 13 of the strands 10 'and 1,1 providing loop openings lll facing transverse to the plane of the fabric. It is to be understood thatthe strands 10 and 11 are preferably not spirally twisted, but the bent portions at the ends cross each other at locations 17. Weft yarns or threads 20 'are provided, which are preferably rather taut,'and which are threaded through the loop openings 14 of the warp wires; 5@ the interweaving of the weft or ller yarns 20 through the loop openings 14 being such that all of the bends 12 of the wire strand 10 will lie at one face of the fabric, and the bends 13 will lie at the other face of the fabric, as shown in Figure 1, Intermediate ller or weft yarns 24 are provided,

which alternate with the weft yarns 20, and which extend in interweaving relation between the strands 10 and ll preferably exactly atv the cross locations I7 of the strands lo and 11; the resistance and rigidity of the wire warp strands 10 and S0 11 holding the weft yarns 24 in positions. These intermediate filler or weft yarns 24 are slack, and not so taut as the weft yarns 20,*and define outstanding loops 25 between the parallel series of warp wires; these loops 25 either lying in the plane 65 ofl the fabric or extending transverse at either s ide thereof to produce a terry effect.

In the form of invention B the flexible wire warp strands are interwoven with the weft yarns i in approximately the same relation as is above described for the preferred form' of invention A, except that for each series of flexible wire warp threads or strands two pairs of the sinuously .interwoven exible warp wires are provided, the

pairs for each series being independently interz5 woven with the weft yarns or threads in close side-by-side relation. Thus, as shown in Figure 2 of thedrawing each series of flexible wire warp strands includes a pair of cooperatively sinuously wound strands '10 and 11a and a second pair of an cooperative sinuously wound wire warp strands 10b and 11b. The pairs of strands 10m-11a and 10b-11h are wound in crossed sinuously opposed relation to provide for the respective pairs in each series the loop openings 14 and 14b through g5 which the taut weft yarns 20il are threaded, with all of the bends of the wircstrands 10 and 10b in each series lying to one side of the fabric and the bends of the other wire strands 11a and 11.h lying to the opposite side of the fabric. Other oo weft iiller yarns 24a are -interwoven alternately with the yarns 20'? through the wire weft strands, being caught at the cross portions of the pairs of wire warp strands as shown in Figure 2, to define slack loops 25' extending to one side or the other 95 `or in the plane of the fabric between the series to be distinctly under-smid that the terms warp" ma Aand weft are interchangeably used, since the wire strands herein described may just as appropriately be placed in the fabric as weft yarns.

The wire strands preferably comprise copper wire bodies designated at 4o in the drawing noVl which are suitably coated either by means of cotton winding material, or some liquid coating material, without destroying the ilexibility there o1' and providing a. frictional surface in contact with the intermediate weft yarn. 20 and 24between the loops 25 and 25"'. warp strands may be ofv any alloy desired, or may be of brass, steel, aluminum, or the like. 'Ihe copper Wire is preferably used for electrical purposes, and is of a composition which is very soft to properly enable its use in the fabric, but which is still suitably conductive for electrical purposes. 'Ihe use of the wire in the cloth shows a large increase in the breaking strength of the same over conventional cotton yarn cloths or the like. The application of the wires under the principle described may be utilized in connection with rayon, silks, worsteds, velours, sateens and the like.

It is to be particularly noted that the weft yarns are made of a plurality of untwisted strands of ber, such as rayon, although twisted weft Yarns of fabric or other material may be utilized instead of that shown. It is within the contemplation of the invention to utilize both warp and weft strands of wire material.

Various changes in the shape, size, and arrangement of parts may be made to the forms of invention herein shown and described, without departing from the spirit of the invention or the scope of the claims.
