Patent number: 5609935Abstract: This invention is directed to a fur-like pile fabric of two-layer construction formed of guard hair fibers and under-fur fibers and used as artificial fur and a method for the production thereof.This invention produces a pile fabric 1 possessing guard hair fibers 2 having sharpened leading terminals and under-fur fibers having a satisfactorily uniform length by a method that comprises preparing a pile knitted or woven fabric with a pile yarn obtained by mixing limited-length polyester type fibers for guard hair fibers of sharpened terminals with limited-length polyester type fibers more susceptible to the action of an alkali treating agent and used for under-fur fibers, imparting an alkali treating agent 6 of a specific viscosity to the hair-raised surface of the pile knitted or woven fabric, and thereafter heat-treating the alkali-treated fabric thereby shortening the under-fur fibers and sharpening the leading terminals of the under-fur fibers.Type: GrantFiled: October 27, 1994Date of Patent: March 11, 1997Assignee: Toray Industries, Inc.Inventors: Seiichi Yamagata, Hidenobu Honda

Artificial fur having guard hair fibers and under fur fibers and a method for manufacturing the same
Patent number: 4415611Abstract: In an artificial fur made from a pile cloth provided with a ground construction and numerous pile fibers projected upward from the ground construction, the pile fibers consist of a first group of pile fibers which form a layer of guard hair in the fur and a second group of pile fibers which form a layer of under fur in the fur, wherein each fiber of the first group is provided with a tapered free end portion and a tapered end portion firmly held by the ground construction; the pile fibers of the first group are longer than the pile fibers of the second group, while the thickness of the main portion of the former is thicker than the thickness of the latter. The above-mentioned artificial fur is manufactured by a first step of forming a material pile cloth provided with a ground construction and numerous yarn-like piles projected upward from the ground construction, and a second step of raising the side of said yarn-like piles.Type: GrantFiled: September 10, 1981Date of Patent: November 15, 1983Assignee: Toray Industries, Inc.Inventors: Seiichi Yamagata, Masaaki Sakai -
