Application January 13, 1938, Serial No. 184,78?

1 Claim.

The present invention relates to chenille yarn and has as its principal object the provision of a chenille yarn which is elastic so that it may be stretched longitudinally. The invention contemplates the provision-of a chenille yarn which, because of its longitudinal elasticity, has the chenille thread or transversely extending fibers compressed together .so as to provide a good body that is much more full than ordinary chenille, yarn.

The advantages of the present invention are particularly noticeable when the chenille yarn is made upinto fabrics, as it imparts to the fabric an elasticity in all directions so that a garment made of this chenille yarn may stretch and return to its original shape in a manner which has not heretofore been possible.

The present invention is applicable to chenille yarn, whether made by the weaving or twisting principle. Furthermore, it applies equally well to out and uncut chenille yarn, as will be readily understood from the following disclosure. The materials which are used as chenille thread, or weft thread, may be any of the known textile or fibrous materials such for example as wool, silk, cotton, rayon, cellulose acetate, hemp, jute or hair. For the core strands of the yarn I may use elastic threads of any suitable construction, either with or without added strands of nonelastic material.

Thev features and advantages of the invention will appear more fully as the description proceeds,

reference being had to the accompanying drawing wherein a preferred example of the invention is shown. It is to be understood, however, that the drawing'and description are illustrative only and are not to be taken as limiting the invention except insofar as it is limited by the claim.

In the drawing, Fig, 1 is a somewhat diagrammatic view illustrating the core strands or warp used in the chenille yarn; 1

Fig. 2 is a view showing how the chenille filler or weft thread is Woven between the core strands and cut to produce chenille yarn; and 7 Figs. 3, 4 and 5 are cross sectional views illustrating chenille yarn with varying amounts of elastic material incorporated therein.

In making the chenille yarn, whether it is made by weaving or twisting, I prefer to take the core or warp strands'shown at 6, I, 8 and 9 in Fig. 1 and stretch the elastic strands which are considerably shorter than the non-elastic strands before weaving in the filler threads. In Fig. 1 the strands I and 9 are elastic, being preferably 5 composed of rubber which may or may not be wrapped'with a covering. of a fine textile thread. The warp strands 6 and 8 are of any non-elastic material such as any of the materials used as weft threads.

. In weaving the chenille yarn I stretch the elastic strands of the core or warp until they are under considerable tension, and then weave in the filler or weft material in the usual fashion. The groups of core strands are then separated by cutting the filler material between the groups to produce chenille yarn. I have illustrated the manner of weaving chenille yarn, althoughit is obvious'that twisted chenille yarn could also be made with one or more elastic core strands. In Fig. 3 I have shown in cross section a chenille yarn in which two of the core strands are rubber and two of the core strands are textile. In Fig. 4

all of the core strands are of rubber, and in Fig. 5 only one core strand is of rubber. In all forms of producing the chenille yarn, however, it is prefe erable that the elastic core strands be stretched during the formation of the yarn, so that when the yarn is completed the tendency of the elastic strands to return to their original length will compress the filler threads and make a full-bodied chenille yarn. In the yarn as completed the nonelastic threads will of course be loose and free of tension, so that the yarn is not still or unwieldy. The elastic strands, however, remain under some tension due to the opposition of the filler material to their return to original length. The resulting product is an elastic chenille yarn in which the filler or weft materials are closely packed and held together under tension by the 4 elasticity of the core strands.

Having thus described my invention what I desire to claim. as new and secure by Letters Patent is: v

A chenille yarn having core strands, certain of said core strands being elastic and under tension whereby the yarn is compressed longitudinally and may be stretched.
