Abstract

본 발명은 열수 또는 약한 알칼리 용액에서 쉽게 용해될 수 있는 폴리에스테르 섬유의 제조방법에 관한 것으로, 테레프탈산과 에틸렌글리콜을 주된 구성성분으로 하는 폴리에스테르의 중합에 있어서, 테레프탈산 성분에 대하여 3∼8몰%의 5-설포이소프탈산나트륨, 2∼10몰%의 비스페놀 유도체 및 전체 폴리머에 대하여 0.1∼5%의 분자량 100∼400인 폴리알킬렌글리콜을 첨가하는 것을 특징으로 하는 개질 폴리에스테르를 중합하여 이로부터 제조된 섬유의 강도가 적어도 데니어당 2.5그램 이상인 수가용성 폴래에스테르 섬유의 제조방법.The present invention relates to a method for producing a polyester fiber that can be easily dissolved in hot water or a weak alkali solution, wherein 3 to 8 mol% of the terephthalic acid component is present in the polymerization of a polyester composed mainly of terephthalic acid and ethylene glycol. 5-modified sodium sulfoisophthalate, 2 to 10 mol% bisphenol derivatives and polyalkylene glycols having a molecular weight of 100 to 400 with a molecular weight of 0.1 to 5% were added to the whole polymer. Method for producing a water-soluble polyester fibers having a strength of at least 2.5 grams per denier from the produced fiber.
