Abstract

본 발명은 1개 층 이상을 신장시킨 다음 이 신장된 층에 다른 층을 부착시킨 2이상의 층으로 이루어진 벌크한 신장 필로우형 라미네이트에 관한 것이다. 일실시 태양에 있어서, 열가소성 필름은 영구 변형될 때까지 신장된다. 이어서. 신장된 상태로 있는 동안 부직웹을 이 필름에 적층시키고, 생성된 복합체를 다소 이완시킴으로써 부직포 층을 주름지게하고 오므라들게 하여 보다 두껍고 벌크한 촉감 및 외관을 제공한다 본 발명의 재료는 광범한 용도를 갖지만 기저귀, 훈련 팬티 및 생리대를 포함한 개인 위생용 횹수 용품의 외부커버로서 사용하기에 특히 적합하다.
