Abstract
본 발명은 인공피혁제품의 소재로 유용한 피혁상 시트물의 제조방법에 관한 것으로서, 극세화가 가능한 섬유로 이루어진 부직포에 폴리에테르계 폴리우레탄과 폴리에스테르계 폴리우레탄을 디메틸 포름아마이드에 완전히 용해하여 블렌딩한 탄성 고분자 물질을 함침처리하고 응고, 건조후 가송소다를 투입하여 극세화하므로써, 유연성이 우수한 피혁상 시트물을 제조하는 방법에 관한 것이다.The present invention relates to a method for manufacturing a leather-like sheet material useful as a material for artificial leather products, the polyether-based polyurethane and polyester-based polyurethane in a nonwoven fabric made of ultra-fine fibers completely dissolved in dimethyl formamide blended elastic The present invention relates to a method for producing a leather-like sheet having excellent flexibility by impregnating a polymer material, coagulating and drying and then minimizing by adding condensed soda.
