SYNTHETIC FIBER, FABRIC, METHOD FOR PRODUCING SYNTHETIC FIBER, AND METHOD FOR PRODUCING SYNTHETIC FIBER FABRIC

摘要

PROBLEM TO BE SOLVED: To obtain a synthetic fiber suitably usable as an environmetal clean-up material such as a filter for cleaning air or water, and to provide a method for producing such a synthetic fiber.;SOLUTION: This synthetic fiber is obtained by exposing, as the photocatalyst, titanium oxide powder 2 coated with an inert porous film 22 onto the surface of a synthetic fiber 1. Specifically, for example, this synthetic fiber is obtained by forming a polyester polymer incorporated with, as the photocatalyst, titanium oxide powder 2 coated with an inert porous film 22 into a fiber followed by melting and removing the surface of the resultant polyester fiber with caustic soda to effect exposure of the titanium oxide powder 2 onto the resultant surface of the fiber.;COPYRIGHT: (C)2001,JPO
