The invention relates to a low permeability and high strength woven fabric and methods of making the same. A method for producing a woven fabric comprises weaving fibers in a warp direction and a weft direction to form a fabric having a top surface and a bottom surface, wherein the warp fibers and weft fibers each comprises one or more filaments of a synthetic polymer having substantially uniform cross-sectional composition. At least a portion of the filaments in the fibers on the top and/or bottom surface of the fabric are then fused together in the presence of a heat transfer liquid or vapor added during the fusing step or added in a prior step of the fabric production process and retained by the filaments. The fusing step produces a treated fabric having a tensile strength in both the warp and weft directions of 1000 N or greater and having, in the absence of any coating, a static air permeability (SAP) of 3l/dm<2>/min or lower.

    本发明题为“低渗透性和高强度织造织物及其制造方法”。本发明提供了一种用于产生织造织物的方法,该方法包括沿经向和纬向编织纤维以形成具有顶部表面和底部表面的织物,其中经向纤维和纬向纤维各自包括一根或多根合成聚合物长丝,该一根或多根合成聚合物长丝具有基本上均匀的横截面组分。然后在熔合步骤期间添加或在织物产生过程的先前步骤中添加并被长丝保留的热传递液体或蒸气存在的情况下,将织物的顶部表面和/或底部表面上的纤维中的长丝的至少一部分熔合在一起。该熔合步骤产生经处理的织物,该经处理的织物在经向和纬向上均具有1000N或更大的拉伸强度并且在不存在任何涂层的情况下具有3l/dm2/min或更低的静态透气性(SAP)。
