Abstract

본 발명은 100℃ 이하의 상온ㆍ상압에서도 염색이 가능하여 천연섬유나 열에 약한 섬유와의 혼섬ㆍ염색시 섬유 형태가 거의 변하지 않고 염색불량이 없는 염색이 용이한 폴리에스테르 섬유의 제조방법을 제공하는 것을 그 목적으로 하는 것으로서, 폴리에스테르 섬유의 제조에 있어서, 디카르본산 성분으로서 테레프탈산을 95몰% 이상 함유하고, 디올성분으로서 에틸렌글리콜을 95몰% 이상 함유하는 폴리에스테르 수지 조성물에 개질성분으로서 폴리옥시알킬렌글리콜 4,5 내지 7중량%를 공중합시켜서 중합물을 제조한 뒤 이를 통상의 방법으로 방사하여 제조함을 특징으로 한다.The present invention provides a method for producing a polyester fiber that can be dyed even at room temperature and atmospheric pressure of 100 ° C. or lower, and thus, when the fiber is mixed or dyed with natural or heat-sensitive fibers, the fiber shape hardly changes and dyeing is not easy. For the purpose of producing polyester fibers, a polymodified polyester resin composition containing 95 mol% or more of terephthalic acid as a dicarboxylic acid component and 95 mol% or more of ethylene glycol as a diol component is used as a modifying component. 4,5 to 7% by weight of oxyalkylene glycol is copolymerized to prepare a polymer, and then it is characterized in that it is prepared by spinning in a conventional manner.
