Patented May 17, 1938 UNITED STATES ELASTICI FABRIC John V. Moore, Pawtucket,

R. I., assignor to Moore Fabric Company, Pawtucket, R. I., a corporation of Rhode Island Application November 1 Claim.

This invention relates to elastic fabrics capable of general application for garment purposes and particularly adapted for use in garters and in other similar products where increased stiffness 5 combined with a decorative effect is desired.

It is the general object of my invention toprovide an improved construction in such fabrics, so designed that an exceptionally open fabric is attained, which fabric, however, will remain fiat when in use and will have little or no tendency to roll at the edges.

A further feature of the invention relates to the provision of a new and novel construction in covered non-elastic yarn, particularly adapted for use as weft in garter fabrics and for other similar purposes.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claim.

A preferred form of the invention is shown in the drawing, in which Fig. 1 is a diagrammatic plan view showing a preferred weave for my improved fabric; and

Fig. 2 is a. plan view of a portion of the novel weft yarn used in the fabric.

'I'he fabric shown in Fig. 1 is elastic longitudinally only and comprises elastic selvage warp threads I0, additional elastic warp threads II in the body of the fabric, non-elastic warp threads I2 and leno warp threads III, together with nonelastic weft yarn 20.

The elastic warp threads I 0 and II are preferably, although not necessarily, of the covered rubber type commonly used in elastic fabrics.

The weft 'yarn 20 is of special construction and comprises a body portion of non-elastic fibers and a covering comprising one or more windings of non-elastic threads, such as silk or rayon, Wound spirally around the body portion of the 9, 1936, Serial No. 109,959 (Cl. 139-421) yarn and preferably comprising inner and outer windings of opposite hand. This weft yarn will be found to have its stiffness very substantially increased by the addition of the windings or covering layers thereon.

Such a weft yarn may be used in a wide variety of fabrics, one of which is illustrated in Fig. l, wherein the weft yarn 20 is'inserted in double picks between. the crossings of the leno warps I4, thus producing a fabric having substantial openings 25 through which air may circulate freely when the fabric is in use.

The weft yarn 20, being relatively stiff and inflexible and being inserted in double picks, stiffens the fabric transversely and causes the fabric to remain fiat and without tendency to roll or curl at the edges, regardless of the very open character of the weave. Y The winding or covering on the weft yarn 20 may be of silk or rayon, and the covering threads may present any desired color combination, so that this novel weft yarn not only improves the fabric mechanically, as previously set forth, but also adds substantially to its pleasing and ornamental appearance.

While- I have described my improved yarn as weft yarn, it will be understood that it may also be used as warp yarn, should occasion arise.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claim, but what I claim is:

An elastic fabric comprising elastic warp threads, leno warp threads, and covered non-elas tic weft yarn inserted in said fabric in spaced pairs of picks and held in spaced relation by said leno warp threads, the covering of said weft yarn providing increased transverse stiffness for said fabric.

JOHN V. MOORE.
