Abstract

본 발명은 알칼리, 열수 등에 용해성이 뛰어난 공중합 폴리에스테르에 관한 것이다.The present invention relates to a copolyester having excellent solubility in alkali, hot water and the like.

상세하게 말하면 복합섬유의 한성분으로 사용하여 열수등으로 용해, 제거하여 용이하게 극세섬유 및 특수 이형단면사를 제조하기 위한 추출용 공중합 폴리에스테르에 관한 것으로, 에틸렌 테레프탈산의 에스테르 단위를 주성분으로 하고, 금속술포네이트 함유 에스테르단위가 A몰% 함유된 폴리에스테르에 수평균 분자량이 8,000이상의 폴리알킬렌글리콜류를 B중량%첨가하고, 하기 (1), (2)식을 동시에 만족함을 특징으로 하는 추출성 공중합 폴리에스테르.Specifically, the present invention relates to an extractive co-polyester for easily producing microfine fibers and specially shaped cross-section yarns by dissolving and removing by using hot water or the like as one component of a composite fiber, with an ester unit of ethylene terephthalic acid as a main component, Extraction characterized by adding B weight% of polyalkylene glycols having a number average molecular weight of 8,000 or more to a polyester containing A mol% of a metal sulfonate-containing ester unit, and satisfying the following formulas (1) and (2) simultaneously: Sex Copolymer Polyester.

이때 분자량 8,000이상의 폴리알킬렌글리콜류의 함량이 35중량%이하임을 특징으로 한다.At this time, the content of the polyalkylene glycols having a molecular weight of 8,000 or more is characterized in that less than 35% by weight.
