Abstract

본 발명은 극세섬유화가 가능한 3차원교락부직포를 표면온도가 140℃ 내지 200℃인 열칼렌더로 1∼5㎏/㎠의 압력으로 카렌더링한 다음 수용성 고분자 처리하고, 폴리우레탄을 함침시키고 이어서 섬유의 극세화 및 표면버핑공정을 순차적으로 행한 후 폴리우레탄 탄성체를 박막코팅하는 것을 특징으로 하는 인공피혁의 제조방법을 제공하는 것으로, 본 발명에 의하면 구조가 치밀하고 유연하며 굴곡특성이 우수할 뿐 아니라 후가공시 표면의 관이 우수한 인공피혁을 수득할 수 있다.The present invention is a three-dimensional tangled nonwoven fabric capable of microfiberization is calendered at a pressure of 1 ~ 5kg / ㎠ with a thermal calender having a surface temperature of 140 ℃ to 200 ℃ and then treated with a water-soluble polymer, impregnated with polyurethane and then The present invention provides a method for manufacturing an artificial leather, characterized in that a thin film coating of a polyurethane elastic body is performed after the step of miniaturization and surface buffing, and the structure is compact, flexible, and excellent in bending characteristics as well as post-processing. It is possible to obtain artificial leather excellent in the tube of the surface of the eye.
