Abstract

단사섬도가 0.8d미만의 극세섬유로 구성되며, 또 인장강도 6.5g/d이상 및 파단신도 15%이상을 보유하는 고강도 멀티필라멘트로 구성된 고가도극세섬유구조물이다.
해도형 복합방사에 의해 복합섬유사가 제조되며, 섬유구조물로 한 후,극세섬유화를 실시할 수 있다.
고강도의 극세섬유로 구성되며 또 높은 커버팩트 ()를 얻을 수 있기 때문에, 극세섬유를 사용함으로써 우수한 효과를 충분히 발휘할 수 있다. 또 목적에 따라서 자체투과성을 낮게 할 수 있다. 따라서 우수한 기계적 특성과 아울러 우수한 유연성도 보유하는 섬유구조물이 얻어지며, 또 보풀이나 실끊어짐이 적은 고품질의 섬유구조물로 할 수 있다. 특히 섬유구조물이 포백인 경우, 우수한 기계적 특성, 우수한 유연성, 절첩성 및 낮은 공기 투과성을 보유할 수 있다.
