Abstract

본 발명은 섬도를 보다 극세화하여 볼륨감과 촉감을 크게 개선시킨 은면형 초극세사 부직포 인공피혁의 제조방법에 관한 것이다. 본 발명의 은면형 초극세사 부직포 인공피혁의 제조방법은 나이론 또는 폴리에스테르와 폴리에틸렌의 극세집속형으로 혼합방사한 다음 단섬유화 및 부직포화하여 니들펀칭에의해 3차원 입체 교락구조로 교락시키는 과정, 상기 부직포에 에스테르 타입의 폴리우레탄 수지를 함침시키고 수용성 고분자를 처리하여 기포에 형태안정성을 부여하는 과정, 다음에 상기 부직포를 테트라클로로에틸렌 혹은 톨루엔에 침지처리함으로써 구성섬유로부터 폴리에틸렌 성분을 용출시켜 구성섬유의 섬도를 0.005 내지 0.001 데니어 수준으로 초극세화시키는 과정, 결과되는 부직포에 고형분 30 내지 50%의 일액형 선상 폴리우레탄을 코팅하고 엠보싱롤을 이용하여 열고정시키는 과정을 포함하여 이루어지는 것을 특징으로한다. 본 발명에 따르면 천연피혁과 유사한 볼륨감 및 웨트(Wet) 터치, 부드러운 감촉을 지닌 유연한 은면형 초극세사 부직포 인공피혁이 제공되는 효과가 있다.The present invention relates to a method for producing a silver-type super-microfiber nonwoven artificial leather that has improved the fineness of the fineness and greatly improve the sense of volume and touch. The manufacturing method of the surface-type ultra-microfibre nonwoven artificial leather of the present invention is a process of entangled into a three-dimensional solid entanglement structure by needle punching by mixing and spun into a nylon or polyester and a micro-focused type of polyester and polyethylene, then short fibers and non-woven fabric, the nonwoven fabric Impregnating an ester-type polyurethane resin and treating water-soluble polymer to impart morphological stability to the bubbles. Then, the nonwoven fabric is immersed in tetrachloroethylene or toluene to elute polyethylene components from the constituent fibers to obtain fineness of the constituent fibers. Ultrafine to 0.005 to 0.001 denier level, characterized in that it comprises a step of coating a one-component linear polyurethane of 30 to 50% solids on the resulting nonwoven fabric and heat-setting using an embossing roll. According to the present invention, there is an effect of providing a flexible silver-cotton microfiber nonwoven artificial leather having a volume and wet touch similar to natural leather, and a soft touch.
