- This invention relates to an improved composite fabric containing a textile fabric having its yarns retained in a greater spaced relation in respect to each other in some areas than in others by a composition network adhered thereto, thereby increasing the porosity of the textile fabric opposite the openings in the composition net work and/or producing ornamental designs therein. The invention also relates to the method of making such composite fabric.

Heretofore it has been the practice to arrange the threads in a textile fabric during the construction of the fabricso as to form lace work designs therein, wherein the threads in certain areas are spaced farther apart than in other areas. In accordance with the present method an extendible textile fabric may be woven, or knitted or otherwise constructed without worked in designs and with a uniform surface appearance throughout, and'the spacings of the threads may be thereafter changed by adhering a plastic composition network to the.fabric, then stretching the network in the plastic state with the fab-- ric, and setting the composition network on the textile fabric in the stretchedposition.

In the resulting composite fabric the yarns opposite the openings in the composition network are spaced farther apart than the yarns of the textile fabric opposite to the composition of the network. The face of the composite fabric, that is, the surface of the side not in contact with the network, has a lace work design formed thereon, in which relatively large openings are formed between the yarns opposite the openings in the network, and the yarns are retained in a relatively closely compact relation opposite the composition to which they are adhered.

Pronounced high and low light reflecting effects are produced on the face side of the composite fabric. particularly when the textile fabric has a high gloss, such as is found in silk, or silk-like fabrics, for example, rayon and similar fabrics. The high lights emanate from the areas of the textile fabric opposite the composition network in which the threads are retained relatively close together, and the low lights emanate from the areas of the textile fabric opposite the openings in the network in which the threads are not retained in such close relation and may be 11 Claims. (Cl. 154- 48) the textile fabric, and sueh elastic porous fabrics containing knitted rayon or silk-like textile fabr-ic are particularly useful for bathing suit and other wearing apparel material.

The invention is described in further detail in reference to the accompanying drawing, in which:

Fig. l is a plan view of an extendible piece of textile fabric having no designs formed therein during its construction by the interlacing of the yarns: 1

Fig. 2 is a plan view of the fabric shown in.

Fig. 1 having a net work of plastic composition applied thereto;

Fig. 3 is a plan view of the composition network side of the finished composite fabric embodying this invention, 'which results from stretching the fabric from the position shown in Fig. 2,'and setting the plastic composition network; and

. Fig; 4 is a plan view of the face, or textile side of the finished fabric, which is the reverse side of the composite fabric shown in Fig. 3.

The finished relaxed composite textile and composition fabric l0 embodying this invention is shown in Figs. 3 and 4 of the drawing. Fig. 3 illustrat'es the side of the textile fabric H having the composition network [2 adhered thereto, and Fig. {illustrates the face of the textile fabric ll back side. Referring to Fig. 4, the yarns l3 of the textile fabric l-l are spaced farther apart opposite the openings H in the composition network I 2 than the yarnsin the textile fabric in the bands l5 which are adhered to the composition.

Such a construction produces a lace work effect in the fabric, and increases the porosity of the textile fabric opposite the openings I 4.

The composite textile and composition fabric is made by applying an open network l2 of plastic composition as shown in Fig. 2 to an unfigured stretchable textile fabric H, such as shown in Fig. '1. After the plastic network I2 has been applied, thetextile fabric II with the network thereon is stretched transversely, that is, in the direction of the double arrow A. When so stretched the composition network l2 retains the .yarns of the textile fabric I I in the bands l5 substantially in the position they occupied at the time the composition I2 was adhered thereto, excepting thatsome of the lines l6 of the textile fabric in' the bands l5 are caused to assume a curved arrangement. The yarns are spread farther apart in the openings ll ofthe network, thereby making larger openings I3 between the y m L As shown in Fig. 2 the openings H are originally formed in a diamond shape, and when the composition network is stretched laterally in the direction of the double arrow A, the vertically opposite corners of the diamonds are drawn closer together, as the horizontally opposite corners of the diamonds recede from one another. As shown in Fig. 3 the diamonds assume substantially the shape of a square. In this transformation, the composite fabric as shown in Fig. 2 becomes narrower in the direction transverse to the stretch and more elongated inthe' direction of stretch, as shown in its final position in Fig. 3. However, if the textile fabric II is extendable in both the horizontal and vertical directions (having reference to Fig. 2), the textile fabric with the plastic composition thereon may be stretched in both directions, and the general diamond shape of the openings It may be retained. In the latter case, the appearance, or arrangement of the yarns I 3 may be slightly different, but the spreading of the yarns orlace work effect of the textile fabric oppositethe openings I4 in the network may be produced. Of course other shapes of openings in the network l2 may be used to produce various designs on the finished fabric.

After the textile fabric H with the composition network l2 thereon has been stretched a suitable amount, for example in the proportion as shown by Figs. 2 and 3, the composition network I2 is set in its finished or final condition. When the composition is set or cured, it retains the relative positions of the yarns l3 of the textile fabric II as shown in Figs. 3 and 4.

' The composition network may be deposited directly on the textile fabric from coating materials which are capable pf being applied in the liquid .or plastic state, and thereafter stretched and set without losing their adhesion and strength required to retain the textile fabric in its final adjusted position. Depending upon the degree of elasticity desired in the network, nitrocellulose, vinyl resin, and rubber containing coatings are suitable. For the purpose of making an elastic fabric, it is preferred to make the composite fabric from a textile fabric provided with considerable initial stretch and having a network of rubber deposited thereon from a rubber containing fluid, preferably a latex composition.

The plastic composition network maybe applied and adhered to the textile fabric bytransferringjt from inte connected grooves in the surface of an applicalkg roll as it is rolled in contact with the fabric in accordance with the known practice. The plastic network may be extruded onto and adhered to the fabric from suitably arranged nozzles as described in co-pending Hawley and Dorazio patent application Serial No. 425.- 572, filed January 3, 1942, for Method of depositing liquid rubber in an open network, of which I am one of the joint inventors.

The elastic composite fabric is preferably made from a knitted textile fabric having a network of rubber composition deposited thereon. -The plastic rubber composition is preferably deposited on the fabric from an extruded rubber latex composition in accordance with the process described in said application. The knitted fabric is then stretched in at least one direction and the deposit of rubber is set and cured, in the usual manner to produce an elastic network. In stretching the knitted fabric prior to setting the rubber thereon, all of the original stretch is not removed but considerable stretch is left in the fabric, so that it can be stretched further after the rubber has been cured, and when the fabric is in a relaxed or unstretched condition.

If desired the knitted fabric may be stretched in two directions transverse to one another prior to setting the rubber, but if elasticity is desired in the relaxed finished fabric in both directions, some further stretch must be left in the fabric in each such direction.

It has been found that relatively fine gauge knitted fabrics, such for example as those knitted on a spring beard circular-knitting machine having about 28 needles to the inch of the circumference, give excellent results when treated in accordance with this process. Very pleasing, or attractive design effects are produced on such fine gauge knitted fabrics having a high gloss, such as rayon, silk or the like. In such fabrics the high and low light effects are very attractive.

As shown herein the composite fabric is made from a single ply of textile fabric H having a composition network I2 adhered thereto. If desired, however, a second ply of textile fabric may be adhered to the composition network l2 after it has been adhered to the first ply H in Fig. 2 so as to sandwich the network between the fabric plies and produce an all textile surface composite fabric by thereafter treating the fabric as described herein.

While the preferred form of this invention has been described herein, the details may be changed without departing from the spirit of this invention or the scope of the claims, and it is desired to claim the invention.as broadly as permitted by the prior art.
