WOVEN OR KNIT FABRIC CONTAINING CRIMPED COMPOSITE FIBER HAVING ITS AIR PERMEABILITY ENHANCED BY WATER WETTING AND RELEVANT CLOTHING

WIPO Patent Application WO/2006/035968

A1

A woven or knit fabric containing crimped composite fibers having its air permeability enhanced by water wetting and being useful in clothes such as outerwear, which woven or knit fabric contains 10 to 100 mass% of composite fibers of side-by-side type or eccentric core sheath type composed of polyester resin component and polyamide resin component whose thermal shrinkages are different from each other, the composite fibers having crimps developed by heat treatment. The composite fibers exhibit humid crimp factor HC_F (%), as measured through a procedure comprising immersing the same in water of 30°C for 2 hr, pulling them up, interposing them between a pair of filter papers at 30°C in a humidity of 90% RH within 60 sec of the pulling up and applying a pressure of 0.69 mN/cm² for 5 sec, of ≥ 10% lower than the dry crimp factor DC_F (%) after dying by allowing them to stand still at 20°C in a humidity of 65% RH for 24 hr, so that the woven or knit fabric exerts of the effect of air permeability enhancement by water wetting.
