Abstract
Abstract A narrow elastic fabric suitable for use in the band encircling portion of articles of apparel. The fabric comprises a set of filling yarns running in the transverse direction of the fabric and a set of warp yarns running in the longitudinal direction of the fabric. The warp yarns comprise elastic yarns, stretch synthetic yarns and nonelastic yarns. There are twice as many stretch synthetic yarns as there are elastic yarns and three times as many nonelastic yarns as there are stretch yarns in the warp set. The nonelastic yarns are woven with the filling yarns in a twill weave whereas the remaining warp yarns are woven with the filling yarns in a plain weave so that the face surface of the fabric is primarily composed of nonelastic yarns.

Claim 1
Independent Claim
212 words
A thin, lightweight, narrow elastic fabric having a face surface and a back surface and suitable for use in the band encircling portion of an article of apparel, said fabric comprising a set of monofilament filling yarns running in the transverse direction of the fabric and a set of warp yarns running in the longitudinal direction of the fabric, said set of warp yarns comprising elastic yarns, stretch synthetic yarns, and nonelastic yarns, there being twice as many stretch synthetic yarns as there are elastic yarns in the warp set and three times as many nonelastic yarns as there are stretch yarns in the warp set, said nonelastic yarns being woven with said filling yarns in a twill weave to form the face surface of said fabric, said face surface being primarily composed of said nonelastic yarns to form a twill pattern on the face surface, said stretch synthetic yarns and said elastic yarns being woven with said filling yarns in a plain weave with at least two stretch synthetic yarns being disposed between adjacent elastic yarns to form the back surface of said fabric, said elastic yarns forming a complimentary diamond pattern on the face surface of said fabric whereby the monofilament filling yarns are covered and stabilized in the fabric.
