| Abstract | PROBLEM TO BE SOLVED: To provide a porous laminate which keeps excellent moisture permeability and an excellent appearance even after a sterilization treatment and is excellent in barrier properties, e.g. blood and virus barrier properties.SOLUTION: A porous laminate contains a polyolefin porous film and a polyolefin fiber layer and shows a moisture permeability after a 30-min heat treatment at 121°C of 150 g/mh and a thermal shrinkage after a 30-min treatment at 121°C of 5% or smaller both in the longitudinal direction and in the width direction.
【課題】滅菌処理した後でも優れた透湿性と外観を維持しており、なおかつ血液バリア性やウイルスバリア性などのバリア性にも優れた多孔性積層体を提供すること。【解決手段】ポリオレフィン系多孔フィルムとポリオレフィン系繊維層とを含んでなる多孔性積層体であり、１２１℃で３０分熱処理した後の透湿度が１５０ｇ／ｍ２・ｈ以上であり、１２１℃で３０分の熱収縮率が長手方向および幅方向ともに５％以下である多孔性積層体とする。【選択図】なし |
