Abstract

본 발명은 95몰% 이상이 폴리프로필렌 성분으로 이루어진 고분자량 섬유형성성 폴리프로필렌 수지와 저분자량 폴리프로필렌 수지를 블렌딩하여 용융, 압출공정을 거쳐 단섬유를 제조함에 있어서, 고분자량 폴리프로필렌 수지와 저분자량 폴리프로필렌 수지를 50:50~90:10 중량비로 혼합하여 이를 방사팩에서 1,000sec-1이상의 전단속도하에서 5~20분간 체류시키고 최종 구금공에서 5,000~50,000sec-1의 전단속도로 압출시키는 것을 특징으로 하는 열융착성 폴리프로필렌 단섬유의 제조방법으로서, 본 발명에 의하면 간단한 방법을 통하여 고생산성으로 복합사와 같이 열츙착성이 우수한 폴리프로필렌 단섬유를 제조할 수 있으며, 이러한 단섬유는 부직포 제조용 원사로 매우 유용하다.
