Abstract

본 발명은 건식으로 표면에 오픈 셀(open cell)이 형성되어 있는 누박형 합성피혁을 제조하는 방법에 관한 것이다.The present invention relates to a method for manufacturing a nubuck type synthetic leather in which an open cell is formed on a surface in a dry manner.

본 발명은 이형지 상에 폴리우레탄 수지조성물을 코팅한 다음 열풍건조하여 오픈셀을 형성시키고, 상기 오픈셀을 갖는 폴리우레탄 필름상에 우레탄계 접착제 조성물을 코팅한 다음 기포를 라미네이팅 하고, 이어서 이형지를 박리시키는 제조방법임.The present invention is coated with a polyurethane resin composition on a release paper and then hot air dried to form an open cell, the urethane-based adhesive composition is coated on a polyurethane film having the open cell and then laminating the bubbles, and then release the release paper It is a manufacturing method.

본 발명은 공정이 간단하면서 셀의 밀도, 크기 및 깊이가 균일한 고품질의 누박형 합성피혁을 제조할 수 있는 방법임.The present invention is a method capable of producing a high-quality nubuck synthetic leather with a simple process and uniform cell density, size and depth.
