Abstract

본 발명은 중공율이 28% 이상인 고중공율의 중공섬유 제조용 방사구금에 관한 것임.The present invention relates to a spinneret for producing hollow fibers having a high hollow fiber ratio of 28% or more.

본 발명은 방사구금의 토출슬릿의 외주부에 토출슬릿의 전체길이의 1/2에 해당하는 지점으로 부터 토출방향으로 4°~10°경사져 있는 테이퍼부를 가진 것을 특징으로 하는 것임.The present invention is characterized in that the outer peripheral portion of the discharge slit of the spinneret has a tapered portion inclined by 4 ° to 10 ° from a point corresponding to ½ of the entire length of the discharge slit in the discharge direction.

아울러 본 발명은 토출슬릿이 다음조건을 만족하는 것임.In addition, according to the present invention, the discharge slit satisfies the following conditions.

- 다 음 -- next -

0.06≤토출슬릿의 두께(mm)≤0.50.06? Thickness of ejection slit (mm)? 0.5
