PROBLEM TO BE SOLVED: To provide a film which is excellent in moisture heat resistance required for a medical fabric though being thin and lightweight and can be formed into a laminated fabric that can exhibit durable blood/virus barrier properties only by being laminated on a fiber fabric; and a laminated fabric thereof.SOLUTION: A moisture heat resistant film is a film which is mainly formed of a polycarbonate-based polyurethane resin, contains acrylic crosslinkable fine particles in the film, and contains 3-20 pts.mass of the acrylic crosslinkable fine particles with respect to 100 pts.mass of the film. A blood/virus barrier laminated fabric is formed by laminating a fiber fabric, a polycarbonate-based polyurethane adhesive layer and the moisture heat resistant film or a fiber fabric and the moisture heat resistant film in this order.SELECTED DRAWING: None 【課題】薄く軽量でありながらも、医療用布帛に要求される耐湿熱性に優れ、しかも繊維布帛に積層するだけで、耐久性ある血液・ウイルスバリア性を発揮しうる積層布帛とすることのできるフィルムと、その積層布帛とを提供することを課題とする。【解決手段】主としてポリカーボネート系ポリウレタン樹脂から構成されるフィルムであって、フィルム中にアクリル系架橋性微粒子を含有し、フィルム１００質量部に対してアクリル系架橋性微粒子を３〜２０質量部含有することを特徴とする耐湿熱性フィルム。及び繊維布帛、ポリカーボネート系ポリウレタン接着層及び上記耐湿熱性フィルム、又は繊維布帛及び上記耐湿熱性フィルムをこの順に積層したことを特徴とする血液・ウイルスバリア性積層布帛。【選択図】なし
