Abstract

용이하게 제조할 수 있으며, 내압 강도가 높고, 여과 정확도가 높으며 여과 수명이 긴 원통형 필터; 이러한 원통형 필터의 제조에 적합한 극미세 섬유 웹 및 부직포; 및 이러한 웹, 부직포 및 원통형 필터의 제조방법이 제공된다.
웹은 용융 취입법에 따라 방사된 극미세 혼방 섬유로 이루어지며, 혼방 섬유는 융점 차이가 10℃ 이상인 고융점 극미세 섬유와 저융점 극미세 섬유로 이루어지고, 저융점 극미세 섬유는 혼방 섬유의 10내지 90중량%의 양으로 함유되며, 부직포는 웹의 열처리에 의해 수득되고, 원통형 필터는 웹 또는 부직포를 권취한 다음 열처리함으로써 수득된다.
