본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

Claims (3)

스웨드조 인공피혁을 제조하는 방법에 있어서, 극세섬 유화가 가능한 복합섬유로 된 부직포를 제조하는 제 1 공정과 섬유를 극세화하고 탄성 고분자물질을 부여하는 제 2 공정, 섬유표면을 버핑하고 염색시키는 제 3 공정 및 열반응형 폴리우레탄프리폴리머를 부여하는 제 4 공정을 거쳐서 인공피혁의 유연성과 반발탄성 및 촉감이 우수하게 되어지도록 하는 것을 특징으로 하는 반발탄성 및 촉감이 우수한 스웨드조 인공피혁의 제조방법.In the method of manufacturing suede artificial leather, the first step of producing a non-woven fabric of a composite fiber capable of microfiber emulsification, the second step of miniaturizing the fiber and imparting an elastic polymer material, buffing and dyeing the fiber surface Method for producing suede-like artificial leather with excellent resilience and touch, characterized in that the flexibility, resilience and touch of the artificial leather is excellent through the third step and the fourth step of imparting a thermally reactive polyurethane prepolymer. . 제1항에 있어서, 상기 제 2 공정시 부여되는 탄성고분자 물질로는 니트릴부타디엔고무나 스틸렌부타디엔고무와 같은 합성고무와 평균부자량이 100,000이상인 DMF가용성 선상 폴리우레탄중에서 선택하여 사용하며, 또한 상기 제 4 공정시 열반응형 폴리우레탄프리폴리머는 그 말단에 함유되어 있는 이소시아네이트기가 중아황산염으로 불로킹되어서 형성되어진 수계유제를 사용하여서 되어지는 것을 특징으로 하는 방법.The method of claim 1, wherein the elastic polymer material to be imparted during the second process is selected from synthetic rubbers such as nitrile butadiene rubber and styrene butadiene rubber and DMF-soluble linear polyurethane having an average molecular weight of 100,000 or more. The thermally reactive polyurethane prepolymer during the process is characterized in that it is made using an aqueous emulsion formed by isocyanate groups contained at the terminals of the sulfite. 제1항 또는 제2항에 있어서, 상기 제 2 공정시의 탄성고 분자물질의 부여량은 해성분을 제거시킨 후 섬유중량에 대해 고형분으로 40 내지 120%로 하며, 제4공정시 열반응형 폴리우레탄프리폴리머의 부여량은 섬유중량에 대해 고형분으로 1 내지 20%로 하여서 되어지는 것을 특징으로 하는 방법.According to claim 1 or 2, wherein the amount of the elastic high molecular material is imparted at the second step is 40 to 120% by weight of the fiber weight after removing the sea component, the thermal reaction type at the fourth step The imparting amount of the polyurethane prepolymer is 1 to 20% by solid content based on the weight of the fiber. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
