    • Breathable barrier fabrics are made by sizing a substrate, made of bonded fibers forming void spaces therein, with a film-forming material that fills the voids of the substrate to form a solid film between the fibers. The resulting non-porous breathable material provides a high strength fabric which is permeable to water vapor, such as body moisture, but impermeable to air and aqueous liquids. The non-porous breathable barrier fabric acts as a barrier against wind, dust or other airborne contaminants, e.g. bacteria, viruses, pesticides, etc., as well as against aqueous liquids such as blood. Alternatively, porous barrier fabrics can be made by incorporating air into the film-forming filler material to obtain greater comfort at lowered barrier qualities. The barrier fabrics of the invention are suitable for industrial, hospital and other protective covering uses.
    • 透气阻隔织物通过将填充基材的空隙的成膜材料定尺寸化由在其中形成空隙空间的粘合纤维制成的基材而制成,以在纤维之间形成固体膜。 所得到的无孔透气材料提供了一种高透水性的织物,其可透水蒸汽,例如身体水分,但对空气和含水液体不透气。 无孔透气阻隔织物作为防风,灰尘或其它空气传播的污染物的屏障,例如。 细菌,病毒,农药等,以及血液等含水液体。 或者,可以通过将空气引入成膜填充材料中来获得多孔阻隔织物,以在降低的阻挡性质下获得更大的舒适度。 本发明的阻隔织物适用于工业,医院和其他保护用途。
