    • A method for manufacturing a P.U. product includes a front stage working, and a rear stage working. The front stage working includes: coating a first P.U. liquid on a releasing sheet to form a first P.U. surface layer, coating a second P.U. liquid on the first P.U. surface layer to form a second P.U. surface layer, bonding a substrate cloth on the second P.U. surface layer, thereby forming a first product which includes the first P.U. surface layer, the second P.U. surface layer, and the substrate cloth. The rear stage working includes: rolling a first mixing liquid on the first product to form a plurality of intensive small air vents in the second P.U. surface layer for increasing permeability, rolling a second mixing liquid containing a fluoride on the first product so that the fluoride infiltrates through the first and second P.U. surface layer for increasing a water repellent function, and rolling a third mixing liquid containing a P.U. solvent on the first product to increase comfort and quality of the first product, thereby making a final product.
    • 制造P.U.的方法 产品包括前台工作和后台工作。 前期工作包括:涂上第一个P.U. 液体在脱模片上形成第一P.U. 表面层,涂覆第二个P.U. 液体在第一个P.U. 表层形成第二个P.U. 表面层,将基底布粘合在第二P.U. 从而形成包括第一P.U.的第一产品。 表面层,第二个P.U. 表面层和基材布。 后段工作包括:在第一产品上滚动第一混合液体,以在第二产品中形成多个密集的小通风口。 用于提高渗透性的表面层,在第一产物上滚动含有氟化物的第二混合液体,使得氟化物渗入第一和第二P.U. 表面层,用于增加防水功能,以及轧制含有P.U.的第三混合液。 溶剂在第一产品上增加第一产品的舒适性和质量,从而制成最终产品。

    • A non-slip, waterproof, water vapor permeable fabric and method of making are described. The fabric is made by obtaining a waterproof, water vapor permeable film and adhering one side of the film to a layer of fabric which may be a stretch fabric. The other side of the film is provided with a discontinuous coating of an elastomer which has an elastic modulus of less than 5.5N/mm.sup.2. The discontinuous coating may take various forms including a pattern of dots or a grid of intersecting lines. The discontinuous coating may optionally project above the surface of the film. The presence of the discontinuous coating of elastomer results in a fabric with a static coefficient of friction of greater than about 1.0 on the discontinuously coated side of the fabric. The film is preferably a porous expanded polytetrafluoroethylene film provided with a hydrophilic coating on one surface; the hydrophilic coating may serve as an adhesive for joining the one surface of the film to the layer of fabric. The inventive fabric is useful for various applications such as articles of medical protective clothing including surgical drapes and liners for orthotic braces, which applications may benefit from the non-slip character of the fabric.
    • 描述了防滑,防水,透水的织物和制造方法。 织物通过获得防水的水蒸汽透过膜并将薄膜的一侧粘附到可以是拉伸织物的织物层而制成。 膜的另一侧设置弹性模量不足5.5N / mm 2的不连续的弹性体涂层。 不连续涂层可以采取各种形式,包括点图案或相交线的网格。 不连续涂层可以可选地突出在膜的表面之上。 弹性体的不连续涂层的存在导致在织物的不连续涂覆侧上具有大于约1.0的静态摩擦系数的织物。 膜优选是在一个表面上设置有亲水性涂层的多孔膨体聚四氟乙烯膜; 亲水涂层可以用作将膜的一个表面连接到织物层的粘合剂。 本发明的织物可用于各种应用,例如医疗防护服的制品,包括用于矫正支架的外科手术用具和衬垫,其应用可受益于织物的防滑特性。
