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.

Claims (3)

고유점도 0.65 이상인 폴리에틸렌 테레프탈레이트를 용융방사, 퀀칭고화한후 제1롤러와 제2롤러 사이에서 연신시 가열접촉면과 냉접촉면이 교호로 배치된 롤러상에서 미연신사의 한쪽면은 가열접촉면과 또다른 한쪽면은 냉접촉면과 접촉시키면서 연신열처리함을 특징으로 하는 잠재권축성 폴리에스터 섬유의 제조방법.After melt spinning and quenching and solidifying polyethylene terephthalate having an intrinsic viscosity of 0.65 or more, one side of the unstretched yarn has a heated contact side and the other side on a roller having alternating hot and cold contact surfaces when drawn between the first roller and the second roller. The cotton is stretched heat treatment while in contact with the cold contact surface. 제1항에 있어서, 가열접촉면의 온도는 100~150℃이고, 냉접촉면의 온도는 5~30℃임을 특징으로 한 잠재권축성 폴리에스터 섬유의 제조방법.The method of claim 1, wherein the temperature of the heating contact surface is 100 ~ 150 ℃, the temperature of the cold contact surface is 5 ~ 30 ℃. 제1항에 있어서, 제1롤러와 제2롤러 사이의 연신비가 1.5~3.5 임을 특징으로 한 잠재권축성 폴리에스터 섬유의 제조방법.The method of claim 1, wherein the draw ratio between the first roller and the second roller is 1.5 to 3.5. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
