Abstract
The invention provides a polyester bicomponent core spun yarn comprising a sheath of at least one hard fiber and having an English cotton count of from about 5 to about 60 and a core of bicomponent polyester filament. The invention further includes a fabric substantially free of grin-through of the bicomponent polyester filament.
Claims30
A polyester bicomponent core spun yarn comprising
- a) a sheath of at least one hard fiber and having an English cotton count of from about 5 to about 60;
- and
- b) a core of bicomponent filament comprising poly(trimethylene terephthalate) and at least one polymer selected from the group consisting of poly(ethylene terephthalate), poly(trimethylene terephthalate), and poly(tetramethylene terephthalate) or a combination of such members,
- wherein the yarn denier is from about 10 to about 100 and the bicomponent filament is from about 5 weight percent to about 30 weight percent, based on total weight of yarn.

A woven stretch fabric having warp and weft yarns and comprising polyester bicomponent filament core spun yarn, wherein
- a) the bicomponent filament core spun yarn comprises
- i) a sheath of at least one hard staple fiber;
- ii) a core of polyester bicomponent filament comprising poly(trimethylene terephthalate) and at least one polymer selected from the group consisting of poly(ethylene terephthalate), poly(trimethylene terephthalate), and poly(tetramethylene terephthalate) or a combination of such members, having an after heat-set crimp contraction value of from about 10% to about 80%;
- and
- b) the fabric is substantially free of bicomponent filament grin-through.

A process for making a stretch woven fabric, comprising:
- a) providing a polyester bicomponent filament comprising poly(trimethylene terephthalate) and at least one polymer selected from the group consisting of poly(ethylene terephthalate), poly(trimethylene terephthalate), and poly(tetramethylene terephthalate) or a combination of such members,
- and having an after heat-set crimp contraction value from about 10% to about 80%;
- b) providing a staple roving yarn selected from the group consisting of cotton, wool, linen, polyester, nylon, and rayon or a combination of such members;
- c) combining the polyester bicomponent filament and the staple roving yarn to make a polyester bicomponent filament core spun yarn wherein the bicomponent filament is drafted from about 1.01× to about 1.25× of its original length;
- d) weaving the polyester bicomponent filament core spun yarn with at least one staple spun yarn or filament to form a fabric selected from the group consisting of twill, plain, satin, and weft rib construction;
- and
- e) dyeing and finishing the fabrics by piece dyeing or continuous dyeing methods.
