Abstract

탄성 복합 부직포 직물 및 그의 제조방법.
본 발명은 스테이플 섬유 또는 천연 섬유를 포함하는 최소한 하나의 섬유상 웨브를 포함하고, 그 웨브의 최소한 하나의 표면 아래와 그 웨브의 실질적인 불연속 단면 부분내에 우선적으로 배치된 열 가소성 재료의 결합층을 가지는 부직포 직물에 관한 것이다. 그 결합재의 층은 열가소성 멜트블로운 섬유의 층으로부터 파생된 열 융합된 열 가소성 웨브를 포함한다. 결합재의 층은 탄성 또는 비탄성의 직물을 제공하는 탄성층 또는 비탄성층일 수 있다. 결합층은 강도 및 임의의 탄성을 직물에 부가하고 섬유상 층의 섬유를 그 직물에 고정시킨다. 유리하게, 본 발명의 직물은 멜트블로운 섬유의 층과 첫번째 섬유상 층을 포함하는 층으로된 웨브를 히드로인탱글링하고, 열가소성 멜트블로운 섬유에 융합하기에 충분하도록 히드로인탱글링된 층으로 된 웨브를 열 처리함으로써 제조된다.
