Abstract
본 발명은 피막강도가 우수한 합성피혁의 제조방법에 관한 것으로, 폴리우레탄 수지조성물을 코팅, 습식가공하여 합성피혁을 제조함에 있어서 합성섬유기재상에 통사의 폴리우레탄 수지조성물을 코팅하여 폴리우레탄 습식층을 형성시킨 후, 폴리우레탄 습식층의 표면층 일부를 유기용매로 용해시킨 후 건조, 열처리하여 제조됨을 특징으로 하는 합성피혁의 제조방법.The present invention relates to a method for producing a synthetic leather having excellent film strength. In the production of synthetic leather by coating and wet-processing a polyurethane resin composition, a polyurethane wetted layer is coated by a general polyurethane resin composition on a synthetic fiber substrate. After forming a, a method of manufacturing a synthetic leather, characterized in that the surface layer of the polyurethane wet layer is dissolved in an organic solvent, and then dried and heat-treated.
