Chromatophilous polyester copolymer prepared by terephthalic acid process, fiber using the polyester copolymer and preparation method thereof

Polyester copolymer is obtained by copolymerizing polyalkylene glycol ether (1-10 wt.%) having molecular weight of 200-2000, with respect to polymer, by terephthalic acid polymerization method. The G-value which is molar ratio of ethylene glycol to terephthalic acid, is set to 1.05-1.15. Independent...

Zusammenfassung:	Polyester copolymer is obtained by copolymerizing polyalkylene glycol ether (1-10 wt.%) having molecular weight of 200-2000, with respect to polymer, by terephthalic acid polymerization method. The G-value which is molar ratio of ethylene glycol to terephthalic acid, is set to 1.05-1.15. Independent claims are included for the following: (1) polyester copolymer; and (2) polyester fiber obtained by spinning the polyester copolymer.
