Abstract
본 발명은 고유점도 0.65 이상인 폴리에틸렌 테레프탈레이트를 용융방사 한후 이를 연신할때에 제1롤러와 제2롤러 사이에 100~150℃의 가열접촉면과 5~30℃의 냉접촉면을 교호로 설치하고 여기를 통과시켜 연신가열 처리하므로써 단일사조에서 한쪽면은 가열처리되고 또 한쪽면은 냉처리 효과로 인하여 발현되는 잠재권축성 폴리에스터 섬유의 제조방법이다.The present invention alternately install a heating contact surface of 100 ~ 150 ℃ and cold contact surface of 5 ~ 30 ℃ between the first roller and the second roller at the time of melt spinning the polyethylene terephthalate having an intrinsic viscosity of 0.65 or more after stretching It is a method for producing latent crimped polyester fibers in which one side is heat treated and the other side is expressed by the cold treatment effect by stretching and heat treatment by passing.
