Abstract

본 발명은 니들펀치기에 의한 부직포 펠트제조시 형태변형을 최소화하기 위해 보강직물을 사용하여 제조하되 인조섬유는 나일론과 이용성 폴리머의 해도형 복합방사에 의한 0.05d 이하의 극세 복합사를 사용하고 보강직물은 폴리에틸렌을 사용한 이상(二相) 구조의 부직포 펠트를 제조하는 것을 특징으로 하는 부직포 인공피혁의 제조방법을 제공하는 것으로 본 발명은 폴리에틸렌 직물을 보강재로 사용함으로써 니들펀치 과정과 알칼리 감량과정에서 형태변형이 없고 극세사 염색전 과정에서 퍼클로로에틸렌 이나 톨루엔 용제로 폴리에틸렌 직물을 제거함에 따라 극세사 단섬유와 직물간의 염색성 차이로 인한 염색무라가 발생하지 않는 효과와 또 사용한 퍼클로로에틸렌, 톨루엔 그리고 폴리에틸렌은 회수하여 재사용할 수 있어서 제조원가를 절감할 수 있는 잇점이 있다.The present invention is manufactured by using a reinforcing fabric to minimize the shape deformation during the manufacture of nonwoven felt felt by the needle punch machine, but the artificial fiber uses a fine composite yarn of less than 0.05d by the island-in-the-sea composite spinning of nylon and usable polymer and reinforced fabric The present invention provides a method for producing a nonwoven artificial leather, characterized in that the production of a non-woven felt of a two-phase structure using polyethylene, the present invention by using a polyethylene fabric as a reinforcement material deformation of the needle punching process and alkali reduction process As the polyethylene fabric is removed with perchlorethylene or toluene solvent before the microfiber dyeing process, dyeing mura does not occur due to the dyeability difference between the microfiber short fibers and the fabric, and the perchlorethylene, toluene and polyethylene used are recovered. Can be reused to reduce manufacturing costs It has the advantage that you can.
