Abstract

본 발명은 은면조 인공피혁의 제조방법에 관한 것으로, 다음 공정으로 구성된다.The present invention relates to a method for producing a silver artificial leather, and is composed of the following steps.

- - 다 음 - -- - next - -

① 극세화가 가능한 복합섬유로 이루어진 니들펀칭된 부직포에 바인더로서 수성 폴리우레탄을 패딩하여 안정화한 후알칼리 감량으로 부직포 원사를 극세화하여 안정화시키는 공정,① Process of stabilizing by punching aqueous polyurethane as a binder on needle punched nonwoven fabric made of composite fibers which can be micronized, and then minimizing and stabilizing nonwoven yarn with reduced alkali,

② 극세화된 부직포 기재를 폴리우레탄 탄성체로 함침하는 공정,② process of impregnating the micronized nonwoven fabric with polyurethane elastic body,

③수성 폴리우레탄 용액 중량에 대하여 고형분이 4∼10중량%인 수성 폴리우레탄 에멀젼을 피혁상시트 표면을 코팅하는 공정,(3) coating the surface of the leather-like sheet with an aqueous polyurethane emulsion having a solid content of 4 to 10% by weight based on the weight of the aqueous polyurethane solution;

④ 필름으로 성형하여 100% 신장시 모듈러스가 20∼40㎏/㎠이며, 탄성회복율이 70∼80%인 폴리우레탄 고분자 탄성체로 습식코팅하는 공정.④ Process of wet coating with a polyurethane polymer elastomer having a modulus of 20-40 kg / cm 2 and elastic recovery rate of 70 to 80% when molded into a film and stretched 100%.

본 발명에 의하면 기재층내부에 바인더수지가 존재함으로 촉감과 외관이 뛰어나고 형태안정성이 우수하여 신장시 요철의 발생이나 평활성의 불량이 없는 은면조 인공피혁의 제조가 가능하다.According to the present invention, since the binder resin is present in the base layer, the touch and appearance are excellent, and the shape stability is excellent, and thus it is possible to manufacture silver-cotton artificial leather without the occurrence of unevenness or poor smoothness during stretching.
