Abstract

(i) 아라미드 원사를 경사 및 위사로 사용하여 바스켓 조직의 아라미드 직물을 제직한 다음, (ii) 제직된 아라미드 직물을 호제인 수계 폴리우레탄 수지와 물로 이루어진 호제액에 침지한 후 압착 및 건조하여 폴리우레탄 매트릭스 수지와의 접착성 및 인장강도가 우수한 아라미드 직물을 제조한다. 본 발명은 제직된 아라미드 직물에 호제를 부여해 주기 때문에 제직전 아라미드 원사에 호제를 부여해 주는 방법과 비교시 제직 중 호제탈락으로 인한 제직효율 저하를 효과적으로 방지할 수 있다. 또한, 본 발명은 아라미드 직물의 표면 및 내부에 수계 폴리우레탄 수지를 부착 및 함침시켜 주기 때문에 폴리우레탄 매트릭스 수지와의 접착성이 향상되고, 아라미드 직물내 아라미드 원사들의 집속성이 높아져 아라미드 직물의 인장강도가 향상된다. 또한, 본 발명은 바스켓 조직으로 아라미드 직물을 제직하기 때문에 아라미드 직물의 치밀성이 낮아져 폴리우레탄 매트릭스 수지와의 젖음성(Wetting property)이 좋아져 결과적으로는 아라미드 직물과 폴리우레탄 매트릭스 수지 간의 접착력이 향상된다. 그로 인해, 본원발명의 아라미드 직물/열가소성 폴리우레탄 수지 복합재는 자동차 범퍼 등과 같이 내충격성이 요구되는 자동차 부품 소재 또는 전자부품소재 등으로 유용하다.
