Abstract

본 발명은 초고속방사법에 의한 폴리에스터섬유의 제조방법에 관한 것임.The present invention relates to a method for producing polyester fiber by ultra-fast spinning method.

방사속도 6000m/분 이상의 종래의 방법으로 제조한 폴리에스터섬유는 정규사에 비하여 신도가 놓고 비수수축율이 낮은 결점이 있었다.The polyester fiber produced by the conventional method with a spinning speed of 6000 m / min or more had a drawback with low elongation and low shrinkage as compared to regular yarn.

본 발명은 히팅후드로 방사구금하부를 가열시킨 상태에서 6000m/분 이상으로 폴리에스터섬유를 제조할때 권취전에 110~140℃의 열판으로 열처리함으로서 섬유의 비정부분의 배향도와 결정성을 향상시켜 비수수축율을 증대시키도록 한 것이다.The present invention is to improve the orientation and crystallinity of the amorphous part of the fiber by heat treatment with a hot plate of 110 ~ 140 ℃ before winding when producing polyester fiber at 6000m / min or more while heating the bottom spinneret with a heating hood To increase the shrinkage rate.

본 발명으로 제조된 사는 비수수축율이 7~9%, 결정화도가 35~40%이다.The yarn produced by the present invention has a non-shrinkage ratio of 7 to 9% and a crystallinity of 35 to 40%.

Claims (1)

구금하부를 가열시키면서 고유점도 0.65인 폴리에틸렌테레프탈레이트를 방사속도 6000m/분으로 방사한 다음 오일링하고, 이어서 제1고뎃롤러와 제2고뎃롤러에 통과시켜 권취하는 통상의 초고속방사법에 의한 폴리에스터섬유의 제조방법에 있어서, 권취하기전에 사조를 110~140℃의 열판에서 가열처리함을 특징으로 하는 초고속방사법에 의한 폴리에스터섬유의 제조방법.Polyester fiber according to the conventional ultra-high-speed spinning method which spins the lower part of the mold and spins the polyethylene terephthalate having an intrinsic viscosity of 0.65 at a spinning speed of 6000 m / min, followed by oiling, which is then passed through the first and second high rollers. The manufacturing method of the polyester fiber by the ultra-high-speed spinning method characterized by heat-processing a yarn at 110-140 degreeC hotplate before winding up. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
