Abstract

Claims (8)

1. A warp-stretch woven fabric selected from the group consisting of plain, twill and satin construction, comprising:

a plurality of weft yarns and a plurality of warp yarns, wherein from about 15 to about 55 weight percent of the warp yarns are polyester bicomponent continuous filaments comprising poly(ethylene terephthalate) and poly(trimethylene terephthalate) and having an after-heat-set crimp contraction value from about 20% to about 80%.

2. The fabric according to claim 1 wherein from about 22 to about 33 weight percent of the warp yarns are polyester bicomponent continuousfilaments.

3. The fabric according to claim 1 , wherein the bicomponent continuous filament warp yarns are woven separately from other warp yarns in the woven fabric construction.

4. The fabric of claim 1 , comprising from about 13 weight percent to about 28 weight percent polyester bicomponent yarns, based on total fabric weight, wherein the bicomponent yarns are present only in the warp.

5. The fabric of claim 1 , comprising from about 13 weight percent to about 19 weight percent polyester bicomponent yarns, based on total fabric weight.

6. The fabric of claim 1 , wherein a portion of the warp yarns axe selected from the group consisting of: spun staple yarns, monocomponent poly(ethylene terephthalate) fibers, monocomponent poly(trimethylene terephthalate) fibers, polycaprolactam fibers, poly(hexamethylene adipamide) fibers, acrylic fibers, modacrylic fibers, acetate fibers, rayon fibers, and combinations thereof.

7. The fabric of claim 1 , wherein said fabric comprises a twill construction.
