摘要

PROBLEM TO BE SOLVED: To provide stockings which have a UV-cutting effect and allows visual confirmation of the effect.;SOLUTION: A photochromic fiber for stockings contains a photochromic material in fibers composed of a polyamide or polyurethane resin of a melting point of 250°C or lower. The photochromic fiber for stockings is produced by a method including a step of mixing a part of the polyamide or polyurethane resin of a melting point of 250°C or lower with the photochromic material to obtain a photochromic resin master batch and a step of mixing the photochromic resin master batch with remaining polyamide or polyurethane resin and spinning.;COPYRIGHT: (C)2016,JPO&INPIT
