Abstract

고융점 폴리비닐 알콜계 중합체(A) 및 저융점 수용성 중합체(B)를 중합체 (A)용 용매중에서 혼합하여 방사 용액을 제조한 후 생성된 필라멘트가 단면에서 균일하게 고화되도록 용액을 저온 방사시킴으로써 해 성분으로서 고융점 폴리비닐 알콜계 중합체(A)및 도 성분으로서 저융점 수용성 중합체를 함유하는 해도 구조의 섬유를 형성한다. 이러한 섬유에서, 도 성분의 적어도 일부는 섬유 표면으로부터 2㎛ 내부의 섬유영역에 존재하며 섬유 표면은 실질적으로 도 성분을 함유하지 않는다. 이러한 섬유는 일반적으로 매트릭스 상, 즉 고융점 폴리비닐 알콜 섬유의 성능을 나타내나; 섬유를 고온에서 가압하였을 때, 저융점 중합체(도성분)는 섬유 표면으로 밀려나 섬유간에 열 결합이 나타난다. 섬유의 이러한 특성 때문에, 부직포는 섬유로 부터 유리하게 제조할 수 있다.
