摘要： A packing material having improved chemical resistance formed of poly(phenylene) sulfide yarn and polytetrafluoroethylene yarn is provided. Each of the yarns may be treated with PTFE dispersion and, optionally, with graphite. The two yarns may be twisted together or laid-up side-by-side and braided together and the structure may be impregnated with a polytetrafluoroethylene based binder and lubricant. The resulting packing material has improved temperature characteristics, heat transfer characteristics, wear resistance, provides a dense impervious packing and is dimensionally stable in addition to the improved chemical resistance. A packing material prepared from yarns treated only with a PTFE dispersion is especially useful in the paper making industry and for other applications wherein dark colored yarns are not permissible.
摘要翻译： 提供由聚（亚苯基）硫化物纱和聚四氟乙烯纱形成的具有改善的耐化学性的包装材料。 每个纱线可以用PTFE分散体和任选的石墨处理。 这两根纱线可以一起绞合在一起或并排地编织在一起，并且该结构可以用聚四氟乙烯基粘合剂和润滑剂浸渍。 所得到的包装材料具有改善的温度特性，传热特性，耐磨性，提供致密的不透水包装，并且除了改善的耐化学性外，还具有尺寸稳定性。 由仅用PTFE分散体处理的纱线制备的包装材料在造纸工业和其他不允许深色纱线的应用中尤其有用。

摘要： The invention is a method of producing a melt spun synthetic polymeric filament which has the superior deep dyeability thereof. The method includes the steps of application of a dye dispersed in water to the filaments during the drawing of the filament, and heat setting the surface dyed filaments to uniformly diffuse the dye throughout the total cross section of the filaments.
