Abstract

종래 기술의 멀티필라멘트를 이용한 중공사 멤브레인에서의 모우나 보풀로 인한 손상 문제를 해결하기 위하여 본 발명에서는 모노필라멘트를 이용하여 나선형으로 개방형 관형 편물을 제조하고， 이를 고분자 수지에 삽입 (embedding)함으로써 보다 향상된 중공사 멤브레인을 개시한다. 이러한 개방형 관형 편물은 각각의 모노필라멘트에 의해 일정 각도로 직조되어 장사방형 또는 다이아몬드 형태를 특징으로 한다. 가소화된 케이블 상에 모노필라멘트를 직조하여 편물을 형성하고 이 편물 상에 중공사 멤브레인용 고분자 도프를 코팅하여 고분자 내부로 편물이 삽입 (embedding)되고 이후 도프는 웅고된다. 이 때 가소화된 케이블이 중공사 멤브레인의 내경을 결정한다. 상기와 같이 형성된 개방형 편물이 삽입된 중공사 멤브레인은 길이 방향으로의 팽창 (연신)이 가능할 뿐만 아니라 방사상 방향으로도 팽창 가능하여 이축 팽창이 가능하다. 즉 중공사 멤브레인은 길이방향뿐만 아니라 방사상 방향으로도 유연성을 가진다. 이와 같은 방사상 방향에서의 유연성으로 인해 방사상 방향으로의 팽창이 거의 불가능한 멀티필라멘트를 이용한 중공사 멤브레인보다 높은 압력 하에서 역세정이 가능하여 효율을 증대시킬 수 있다.
