극세사의 분할에 있어 각 구성 폴리머의 유리전이 온도를 이용하여 그 온도에서의 열수 수축율 차를 이용하여 각 구성 성분을 분할해내는 극세사의 분할방법.A method of dividing microfiber in which the microfibers are divided by using the glass transition temperature of each constituent polymer using the difference in hydrothermal shrinkage at that temperature.제1항에 있어서, 폴리에스터와 폴리아마이드로 구성된 분할 극세사를 분할하는 경우 폴리아마이드 섬유의 유리전이 온도인 40℃에서 30분 내지 60분 정도 홀딩하고 이어 폴리에스터 섬유의 유리전이 온도인 70℃에서 30분 내지 60분 정도 홀딩하여 두 이종 섬유의 열수 수축율 차를 최대한 유발시켜 이종의 섬유를 분할해내는 극세사의 분할방법.According to claim 1, When dividing the split microfiber composed of polyester and polyamide is held for 30 to 60 minutes at 40 ℃, the glass transition temperature of the polyamide fibers, and then at 70 ℃, the glass transition temperature of the polyester fiber Dividing the microfibers by holding for 30 minutes to 60 minutes to induce the difference in hydrothermal shrinkage of the two different fibers to divide the different fibers.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
