Abstract

본 발명은 폴리에스터 및 알칼리이가수분해 폴리에스터로부터 이루어진 용출 분할형 복합섬유의 제조방법에 관한 것으로, 방사속도, 연신온도 및 연신배율이 하기 식을 만족토록 하고 고데트 롤러 사이에서 직접 연신 후 권취하는 원스텝화 공정으로서, 원사간 물성 균일성 및 생산성을 향상시키고 공정성이 우수한 용출 분할형 복합섬유의 제조방법이 제공된다.The present invention relates to a method for producing an eluted split composite fiber composed of polyester and alkali hydrolyzed polyester, wherein the spinning speed, stretching temperature and stretching ratio satisfy the following formula and are directly stretched between the Godet rollers. As a one-step step taking, a method for producing an elution split type composite fiber which improves the uniformity and productivity of yarns between yarns and has excellent processability is provided.
