ALKALI HYDROLYSIS-RESISTANT POLYESTER FIBER

摘要

PROBLEM TO BE SOLVED: To provide a polyester fiber that is suitable for producing combined filament yarns or blended yarns and fabrics with a regular polyester fiber has increased dyeability and resistance to alkali hydrolysis.;SOLUTION: A specific copolymer is combined with regular polyester fiber to produce the objective modified polyester fiber. Regular polyester fiber is improved its dye dyeability and resistance to alkali hydrolysis by admixing a specific copolymer composition to regular polyester.;COPYRIGHT: (C)2002,JPO
