Amidon, Reading, Pa., assignor to Vanity Fair Mills, Inc., Reading, Pa., a corporation of Pennsylvania SAME Application July 22, 1943, Serial No. 495,749

16 Claims. (Cl. 66-193) My invention relates to a new and. improved composite fabric and method of combining a previously woven base material with a knitting process to produce a composite fabric of a formation and thickness not to be had by any method heretofore known.

More particularly, the invention relates to a method wherein the formation of the process is governed by one thread or yarn feeding device for each needle used. In heretofore known methods of combining a preformed base material with feeding threads or yarns from one knitting chain to another lie upon the other side of the base fabric (see my Patent No. 2,136,367). In a knitting process wherein the knitting threads or yarns knit upon one needle only in a straight line, the

reverse side of the fabric from the knitting chains has no connecting threads or yarns from one chain to another, the feeding thread or yarn running in a nearly straight line with the knitting chains on the side of the fabric opposite from the knitted chains. I

In my Patent No. 2,155,385 straight-line knitting has been followed and an inlay thread has been used to connect the knitting chains on the side of the base fabric opposite that on which the chains lie.

It will be readily seen from the above that in composite fabric construction, where one thread or yarn feeding stitch has been used for each knitting needle, the lay of connecting cross threads or yarns from one knitting chain to another has been in a flat formation or has followed the needle chains in a nearly straight line; therefore, in such construction the threads or yarns laid on the reverse side of the base ma terial from that on which the needle chain stitches lie, lie in a single string formation.

One object of the present invention is to produce a composite fabric and method whereby that part of the knitting which is connected by cross threads or yarns and lies on the side of the I base material opposite that on which the chainloops lie, will be formed by a looping and drawing of the stitching threads or yarns in interlooped loop formations, so that more than one face of the fabric opposite that on which the single thickness thread or yarn chain-loops lie.

Again, it is an object to provide a composite woven-knit fabric of a net-like formation, in which the inter-looped parts are drawn together, thereby drawing the chain loops into zigzag formation, while the inter-loops are held spaced apart at predetermined distances in longitudinal and transverse rows to provide substantial openings through the composite fabric and enable the fabric to 'be used as a liner for light waterproof garments. Previously these garments were composed of a light waterproof outer garment and a liner of fur 0r pile fabric, which made the garments relatively quite heavy and permitted very little air circulation. By substituting my improved fabric for the fur liners and the pile fabric liners it becomes possible to aluminize the inside of the outer garment and thereby reflect the body heat back to the body through the openings in the inner garment. The use of my fabric for the inner garment thus reduces the weight of the combined garment without sacrificing the warming effect of the garment as a whole.

Other objects will in part be obvious and in part be pointed out hereinafter.

To the attainment of the aforesaid objects and ends the invention still further resides in the novel details of construction, combination and arrangement of parts, all of which will be first fully described in the following detailed description, and then be particularly pointed out in the appended claims, reference being had to the accompanying drawings, in which:

Fig. 1 is an enlarged diagrammatic view of a I portion of a fabric embodying my present invention.

Fig. 2 is a view similar to Fig. 1, showing a modification of the same.

In the drawings, in which like numerals of reference indicate like parts in both figures, l and 2 designate the threads or yarns which are knit through the base fabric. The base fabric is composed of warp threads 3 and weft threads 4 woven together, preferably as an open mesh or net fabric.

Each thread or yarn is so knit as to form a row including a chain having loops 5, which loops all lie on the same side or face of the base fabric; each thread or yarn 2 is also knit to form a chain having loops -6, which loops all lie on the same side or face of the base fabric as do the loops 5. The rows of two adjacent threads or yarns are connected through the base fabric by thickness of thread or yarn is looped on the'55 interlooped loops 1 and 8 which are spaced apart from one another longitudinally and transversely at predetermined distances.

The interloops I, 8 lie between adjacent rows of

loops

5 and 6, but on the opposite face of the base fabric, and are connected together by portions of the threads or yarns I, 2 which lie on the same side of the base fabric as do the interloops 1 and 8. The interloops 1 and 8 are drawn together into the form of knots and shall be hereinafter referred to as knot-like elements. The drawing together of the loops 1 and 8 causes the

chain loops

5 and 6 to assume inclinations which give the chains a zigzag appearance. As will be seen from an inspection of the drawings, the

loops

5 and 6 of adjacent chains alternately converge and diverge.

The inclination of the

chain loops

5 and 6, together with the spacing of the inter-looped loops 1 and 8. provide substantial openings through the fabric for light, heat and air to pass. These openings, in the embodiment shown in Fig. l, are all the same size and of quadrilateral form.

Preferably, the

loops

5 and 6 are each crossed by at least two weft threads 4, while at least one warp thread underlies the rows of knot-like elements 1, 8.

If desired, elongated hole may be formed in the fabric by not cross-connecting certain interlooped loops, but effecting longitudinal connections only between certain interloops 1, 8 and 1 8 (as shown in Fig. 2) by th thread portions 2*, I.

When, with relation to the knitting especially, I refer to threads or yarns I wish it understood that these words are used interchangeably and notes limitations.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the construction and advantages of my improved fabric and method of making the same will be clear to those skilled in the art to which it appertains.
