    • Three reusable surgical/medical fabrics provide improved barrier properties, as reflected by their Suter ratings, and also posses a "hand" similar to a "cotton hand". The Suter ratings are degraded in the order of 10% - 20% after 100 sterile reprocessing cycles. The fabrics are reliable free of pin holes, permitting their use as a single layer barrier panel. The fabrics are woven, respectively, with false twist 100/100 warp yarns and air texturized core and effect 2/60/100 fill yarns; flat trilobal 100/50 warp yarns and air texturized core and effect 2/60/100 fill yarns; and false twist 2/50/34 warp yarns and false twist 150/200 fill yarns. The fabrics are characterized by a minimum porosity of at least 10 x 10⁶ pores/square centimeter and maximum average. and mean pore sizes. The fabrics have a thickness of at least .005 inch, a weight of at least 3.5 ounces per square yard and a filament density of at least 2.0 x 10⁶ filaments per square inch. Filament density is obtained by increasing the number of picks in the greige construction to at least about 160 in the finished fabric. In two of the fabrics, the bulk of the greige construction is increased by "mechanically" working the fabric in a ''jet drying machine.
    • 三重复使用的外科/医用织物提供改善的阻隔性能,通过他们的祖特尔的评分反映,因此,拥有一种“手”类似于“棉花手”。 的祖特尔评分劣化在10%的数量级 - 20%100个无菌再处理循环之后。 织物是可靠的无针孔,允许其为单一层屏障面板使用。 将织物编织的,分别与假捻100/100经纱和空气膨体芯和实现2/60/100纬纱; 平三叶形100/50经纱和空气膨体芯和实现2/60/100纬纱; 和假捻2/50/34经纱和假捻150/200纬纱。 所述织物通过至少10×10 <6>孔/平方厘米和最大平均的最小孔隙度为特征。 和平均孔径。 该织物的厚度至少0.005英寸,每平方码至少3.5盎司的重量和每平方英寸至少2.0×10 <6>长丝的长丝密度。 长丝密度是通过在成品织物增加纬纱的数量在坯布施工到至少约160得到。 在两个织物,坯布结构的大部分是通过在“”喷射干燥机“机械”工作的织物增加。
