Abstract

본 발명은 상당히 연속적인 열가소성 필라멘트 제1 및 제2스펀본드 웹(11 및 13) 및 제1 및 제2부직포 웹의 사이에 삽입된 열가소성 멜트블로운 마이크로파이버로 이루어진 소수성 마이크로파이버 부직포 웹(12)으로 이루어진 부직포 복합 재료(0)이다. 스펀본드 부직포 웹의 필라멘트는 낮은 융점을 가지며 감마선 방사에 안정된 폴리에틸렌 폴리머 성분 및 하나 이상의 높은 융점을 가지며 감마선 방사에 안정된 폴리머 성분을 포함하는 연속적인 다성분계 필라멘트로 형성되는데, 다성분계 필라멘트 표면의 상당한 부분은 낮은 융점을 가지며 감마선 방사에 안정된 폴리에틸렌 성분으로 이루어진다. 소수성 부직포 미세 다공 웹은 감마선 방사에 안정된 폴리에틸렌 폴리머로부터 형성된다. 웹은 불연속 점 결합에 의하여 부직포 복합 재료를 형성하기 위하여 결합되며, 점 결합은 상기한 다성분계 필라멘트의 폴리에틸렌 성분 및 상기한 제3부직포 웹의 폴리에틸렌이 상호 융합하여 형성되는 결합이다.
