Abstract

본 발명은 니들펀칭에 의한 부직포를 이용하여 고탄력성을 갖는 인공피혁을 제조하는 방법이 제공되는 것으로, 니들펀칭에 의한 부직포 제조공정 중간에 폴리올과 디이소시아네이트지 함유 반응물인 우레탄계 섬유로 만든 보강직물을 끼워 넣고 부직포를 제조한 후 에테르타이프 폴리우레탄으로 습식코팅 처리하고 크롬계 합금염료염색, 고착제 처리 및 표면처리를 차례로 수행하는 방법이며, 이로부터 수득하는 제품은 종횡방향으로의 탄성력이 뛰어나고 인장, 인열강도가 향상되어 신발용 부직포 스웨드로 적합한 것이다.The present invention provides a method for manufacturing artificial leather having a high elasticity by using a nonwoven fabric by needle punching, a reinforcing fabric made of a urethane fiber which is a polyol and diisocyanate-containing reactant in the middle of the nonwoven fabric manufacturing process by needle punching The nonwoven fabric is inserted and then wet coated with ether type polyurethane, followed by chromium-based alloy dyeing, fixing and surface treatment. The product obtained therefrom has excellent elasticity in the longitudinal and transverse directions, tensile and phosphorus. Its improved thermal strength makes it suitable for shoe nonwoven suede.
