Abstract

본 발명은 섬유상 재료의 부직 웨브로 이루어진 기층 및 하나 이상의 열가소성 필름 층으로 이루어지며, 섬유상 부직 웨브로 이루어진 기층상에 적용된 열가소성 필름이 NFT76-112 표준(박리각동;180° ; 견인 속도:200㎜/mn)에 따라 측정하여 98.10-2kN/m이하인 박리 강도를 갖는 코팅된 부직 재료에 관한 것이다. 본발명은 또한 압출 필름 코팅에 의한 상기 재료의 제조방법에 관한 것이다. 또한 기저귀, 특히 외부 액체 불투과성 배면 시이트로서의 용도에 관한 것이다,

Description

코팅된 부직 재료, 그의 제조방법 및 일회용 위생 흡수 물품에서 그의 용도 (COATED NONWOVEN MATERIAL, METHOD FOR PREPARING SAME AND USE OF SAID MATERIAL IN A DISPOSABLE ABSORBENT HYGIENE ARTICLE)
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
탈리후, 즉 필름 분리후 부직 웨브 표면의 17배 확대 사진인 도 2에서 소량의 열가소성 필름도 관찰되지 않는다. 부직 웨브의 연속 유리 섬유를 혼합하면 열가소성 필름과 부직 웨브 사이에 부분적인 표면 접착을 나타내는 열가소성 필름의 분리에 의해 변형되지 않는다. 부직 웨브 섬유가 부분적으로 용융되어 나타나는 영역은 사실 부직 웨브의 접착면(미리 조밀화된 면)에 해당한다. 반면에 부직 베이스 층의 탈리 휘에 열가소성 필름의 표면의 12배 확대 및 글레이징 광을 사용하여 입체현미경에 의해 얻어지는 사진인 도 3에서는, 접착되는 부직 재료의 표면 섬유의 촉감이 명확히 보인다. 이는 열가소성 필름이 부직 재료 두께에 실질적으로 침투하지 않으면서 표면 섬유의 코팅을 형성함을 명확히 보여준다.
