Patented Aug. 20, 1940 STRIPED ELASTIC FABRIC Norman E. Randall, Shannock, R. I., assignor to Columbia Narrow Fabric Company, a voluntary association of Rhode Island Application July 2, 1940, Serial No. 343,600

3 Claims.

This invention relates to an elastic fabric and has for one of its objects to provide a warp stripe in the fabric which will consist of a section of one color followed by a section of a different color in the desired number of different colors all repeating as the stripe progresses warpwise of the fabric.

Another object of the invention is to provide a stripe of two or more colors extending warpwise of the elastic fabric by means of a leno weave so that the stripe will be on' only one face of the fabric, leaving the fabric plain on the other face.

Another object of the invention is the simplicity in obtaining a variegated colored stripe in an elastic fabric.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawing:

Fig. 1 is a top plan view of a piece of th fabric completed;

these different colored yarns for this purpose.

However, I have arranged to provide a fabric in which a single strand of yarn is itself of dif- I ferent colors and- I have arranged this yarnto form a stripe, the color of the stripe changing as the color of the yarn changes, the length of a section of one color being dependent upon and proportional to' the length that this color appears in the yarn itself; and the following is a more detailed description ofthe present embodiment of this invention, illustrating the preferred means by which these advantageous results may be accomplished:

With reference to the drawing, lll designates generally the [body portion of an elastic woven fabric here shown as of a width usually termed narrow fabric" having warp and filling yarns. As shown in Fig. 2, the non-elastic warp yarns are designated H, and the elastic warp yarns are designated l2. The elastic warp yarns consist of a core of rubber l3 wound with a non- (Cl. 139----421)v elastic covering l4. These elastic yarns 12 are reeded at suitable distances throughout the width of the fabric, while extending lengthwise thereof. The filling yarn is designated generally l5 and is passed back and forth throughout the width of the fabric by a shuttle in a known manner. A leno warp It, as shown in Fig. 2, is the warp which plays the essential part of this invention.

This leno warp forms sections of different colors by itself being of different colors, there being shownin Fig. 3 a length ll of one color, a length l8 of another color, and a length I9 of a third color, and then a repeat of these colors indicated by the length I! of the first color. The manipulation of the heddles and a dupe carrying this yarn I6 is such that it is caused to be placed in a zigzag fashion, as shown in Fig. 2, back and forth across the face of the two parallel elastic yams l2, l2. It is shown as caught by the filling ii at 20 on one side of the parallel rubbers I2, I2, and shown as caughtas at 2| on the other side of the parallel rubbers by the next pick of the filling l5. Thus, each pick of the filling will pass over the leno warp l6, first on one side and then on the other side of the two warp rubbers l2, II, which this leno is to cover to make this zigzag formation as illustrated. in Fig. 2. Each pick will pass beneath the elastic warp l2, l2? which-the leno spans.

This elastic fabric is woven under tension, and when the tension is released, the fabric will contract, and.- the zigzag throws of the leno warp I6 will come together in substantially parallel relation and form a stripe such as shown in Fig. l, the section I! corresponding to the length designated H in the yarn shown in Fig. 3, the section l8 corresponding to the portion l8 in Fig. 3-, and section l9 corresponding to the portion IS in- Fig. 3, and then the portion II again follows to form a sequence of colors, three in number, each contrasting from the other and all contrasting from the body In of the fabric.

It will be readily apparent that the number of colors provided will depend upon the dyeing of the yarn. l6 as shown in Fig. 3. The length of eachsection such as shown in Fig. 1 will depend upon and be proportional to the length of this dyeing, as shown in Fig. 3. Thus, I may provide a stripe dependent upon the single length of yarn which I use and its colors without in any way changing-the remainder of the fabric in which. it is positioned, the entire appearance or color scheme being dependent upon the dyeing of a single length of yarn.

The foregoing description is directed towards the method and construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the equivalent changes to which the construction and method are susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:

1. An elastic woven fabric comprising filling yarns, elastic and non-elastic warp yarns, and a leno warp yarn extending back and forth across the face of one of said elastic warp yarns and caught on either side thereof by the filling yarn, said leno warp yarn comprising lengths of different colors in succession each length of color being sufiicient to provide a plurality of. back and forth crossings of said yarn of such color whereby a solid block of the same color is formed on the surface of the fabric.

2. An elastic woven fabric comprising filling yarns, elastic and non-elastic warp yarns, and a leno warp yarn extending back and forth across the face of one of said elastic warp yarns and caught on either side thereof by the filling yarn,

said leno warp yarn comprising lengths of different colors in succession each length of color being sufficient to provide a plurality of back and forth crossings of said yarn of such color and each length of different color being suflicient to provide a plurality of back and forth crossings of yarn of such different color whereby different solid blocks of each color are formed on the surface of the fabric.

3. An elastic woven fabric comprising filling yarns, elastic and non-elastic warp yarns, and a leno warp yarn extending back and forth across the face of one of said elastic warp yarns and caught on either side thereof by the filling yarns, said leno warp yarn comprising lengths of yam of different 'colors in succession each length of color being suflicient to provide a plurality of back and forth crossings of said yarn of such color whereby a. solid block of the same color is formed on the surface of the fabric and each of the colors of the leno warp contrasting with the color of the other yarns of the fabric.
