| Zusammenfassung: | A hollow fiber membrane of the present invention is a hollow fiber membrane having an outer surface and an inner surface. The inner surface has a zebra-stripe pattern in which dense portions and porous portions are alternately formed along a longitudinal direction. The outer surface has a maximum pore size of 1 μm or less, and a flux of 1,300 to 5,000 LMH/bar. A hollow fiber membrane having excellent mechanical strength and flux is provided.
본 발명의 중공사막은 외부 표면과 내부 표면을 갖는 중공사막이며, 외부 표면과 내부 표면을 갖는 중공사막이며, 상기 내부 표면은 길이 방향을 따라서 치밀부 및 다공부가 교대로 형성된 지브라 스트라이프 패턴(zebra-stripe pattern)을 가지며,상기 외부표면은 최대기공크기가 1㎛이하이고, 수투과도(flux)가 1,300 내지 5,000 LMH/bar 인 것을 특징으로 한다. |
