a great variety of purposes, such as for screens,` radio antennas, or for `use in connection Withlphototone and television work, and which may nd elcient use in connection with millinery, hairdressing, electrical heating pads and clothing pads, and which on a largely modified scale, may be found emcient in connection with the reinforcement of cementitious structures.

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 viewofthe improved fabric, showing the improved relation of warp and weft yarns and the relation by means of which they are tied together. l y l Figure 2 is a view of the reverse side ofthe fabric of Figure 1, turned from left to right.

Figure 3 is an enlarged view showing the relation of the warp to weft or filler yarns.

In the drawing, wherein for the purpose of illustration is shown only a preferred embodiment of the invention, the letter A may generally designate the improved textile fabric, which is preferably composed of metallic Warp threads 10 arranged in definitely spaced parallelism, with which are cooperatively associated the fabric weft threads or yarns 11, tied in upon the warp strands 10 by means of threads 12 which spirally and individually encompass each of the warp threads 10, in an improved cooperative relation therewith.

In view of the intended use of the fabric, it is essentially porous, since the mainuse will be in 'connection with radio art, as screening or antenna fabric, although the improved fabric of this invention is particularly well adapted for use as curtain material and wherever screening or fabric is desirable for use in interior decorating; the fabric being particularly well adapted for such use due to a certain inherent tendency which the same possesses to maintain its original shape, and the ease with which it may be made yto assume a definite shape or form.

' i The entire warp is preferably made of the metallic threads `or strands 10, which' are preferably of electrical conductive material, such as copper, which may be coated orcovered by means of enameling or cotton-winding the same, or enclosing the same in insulation of any approved nature. The materialvof the wire warp strands is not to be limited to copper, since4 it is entirely feasible to use `any desirable alloy-or metal to serve a particular purpose; -it even beingwithin the contemplation of the invention to use silver. Under certain circumferences the warp strands may be left uncovered. However, in the preferred instance, as shown in Figure 3, Ielect to cover the wire body 15*a of' the 'strands Y10, with 'an' insulation coating 16Wliich Vmay be of any approved nature.

I have foundit most economical to use ordinarycotton-wound copper wire, and thesame may be liquid-coated or impregnated.

The weft yarns 11 may be of any approved nature,` preferably/fof* fibrous material, such as cotton, ray,fsilk,`iworsted, or any other material. In the preferred instance the weft yarns 11 areeach made'ofa plurality of luntwisted parallelstrands,` such as shown in Figure 3 of the drawing, which'a're properly tied in and interwoven with the warpfvwires by means of the spirally wound'tying-in` threadsv 12.

The weft yarns l'lare `each'wovenfirrparallel lengths between thewarp'wirs 10; in the -relation shown in the drawing. That is, as more clearly shown in Figure 3, each weft yarn 11 extends in a plurality of parallel lengths 17a and 1'7", sinuously laid back and forth across the spaces between three of the adjacent wire strands 10; the strands 17a and 1'7lo all crossing to one side of the intermediate strand 10, as shown in Figure 3, and the bight portions 18, connecting the lengths 17a and 17h, terminating at the wire strands 10 immediately adjacent and at opposite sides of that strand 10 across which the lengths 17EL and 1'!b extend; these bight portions 18 being each tied in to the adjacent wire warp thread or strand by means of a spirally wound tied-in thread 12. It is thus to be noted that the sinuously wound ller or weft yarns 11 all cross the respective wire strands 10 at one side of the fabric, as is best shown in Figure 1, and the wire strands 10 stand more prominently exposed at the opposite side, as is best shown in Figure 2. The side of the fabric shown in Figure 1 is the right side and it is to be particularly noted that the tie-in yarns 12 are so positioned as to engage thru the bight portions or loops 18 of adjacent filler threads 11 from the upper part 0f the loop of one bight to the lower part ofthe loop of another, in crossing relation with the adjacently related lengths 17h, as clearly shown in Figure 3. Thus, the tie-in yarns do not tie-in the lengths 17a, which due to the crowded nature of the weft, work themselves out on top and the effect of which is to hide or rather secrete the tie-in yarns 12 and the adjacent tie-in portions of the warp and weft yarns. This is especially true since the untwisted strands; making up .the weft yarns or threads 11 will .flufat the ffright'' side of the fabric. This effect is not so pronounced as is shown in the drawing, due'to dif'` fibrous textile yarns disposed upon one side only of the warp.

3. Fabric composed of warp wires in appreciably spaced relation, sinuously wound ller yarns of fibrous material centralized in adjacent pairs of spaces between the warp wires and means connecting said warp wires and the bight portions of the ller wires.

fi. i Fabric composed of Warp wiresin appreciably spaced relation, sinuously Wound ller yarns of fibrous material in adjacent pairs of spaces bev`tween the warp wires, each weft lengthof the culty in proper illustration. The tie-in yarns gsarne being tied in with the alternate warp wires 12 are quite inconspicuous, due to the fact that they are of small size compared to either the at the bght portions of the filler yarn lengths, each length of weft between the bight portions warp or weft yarns, and the relation as to size thereof crossing a warp wire between the spaces between the yarns is somewhat of the `nature shown in Figure 3. f n

The sinuously inter-related weft threadsN may be suitably tied in along the selvage or edges' of the fabric, as can quite readily be.,understood`, and in connection with use ofthe improved textile fabric for radio antenna and screeninguse,

the warp wires may be conductively connected together.

It is to be particularly noted thatthexnie fabric is rather loosely made, andthe spacingof the lengths making up the weftyarns is appreciably closer than the spacing of the wire warp threads. conductive and flexible, and inherently VHmore rigid than the fibrous weft and tie-in yarns, as can quite readily be appreciated.
