    Abstract: The invention provides a process for making a mat particularly a washable dust control mat, having a fabric layer and a rubber backing layer with a border extending beyond the fabric layer using a press which heat-cures the rubber and adheres it to the fabric and employs an inflatable bag to apply pressure by pressing the layers against a heated platen, wherein a frame defining the extent of the border is located between the bag and the platen, and wherein the bag applies pressure to the assembled layers including the border portion of the backing layer. The frame can act as a dam for preventing outward movement of the rubber and provide an integral thickened border; in some cases it also provides a guillotine for trimming the rubber during pressing.

    Abstract: Improvements in preventing heat- and moisture-shrink problems in specific polypropylene tape fibers are provided. Such fibers are basically manufactured through the initial production of polypropylene films or tubes which are then slit into very thin, though flat (and having very high cross sectional aspect ratios) tape fibers thereafter. Such fibers (and thus the initial films and/or tubes) require the presence of certain compounds that quickly and effectively provide rigidity to the target polypropylene tape fiber after heat-setting. Generally, these compounds include any structure that nucleates polymer crystals within the target polypropylene after exposure to sufficient heat to melt the initial pelletized polymer and upon allowing such a melt to cool. The compounds must nucleate polymer crystals at a higher temperature than the target polypropylene without the nucleating agent during cooling. In such a manner, the nullrigidifyingnull nucleator compounds provide nucleation sites for polypropylene crystal growth. Upon slitting of the initial film and/or tube, the fiber is then exposed to sufficient heat to grow the crystalline network, thus holding the fiber in a desired position. The preferred nullrigidifyingnull compounds include dibenzylidene sorbitol based compounds, as well as less preferred compounds, such as sodium benzoate, certain sodium and lithium phosphate salts (such as sodium 2,2null-methylene-bis-(4,6-di-tert-butylphenyl)phosphate, otherwise known as NA-11). Specific methods of manufacture of such inventive tape fibers, as well as fabric articles made therefrom, are also encompassed within this invention.

    Abstract translation: 提供了防止特定聚丙烯带纤维中的热收缩和水分收缩问题的改进。 这种纤维基本上通过初始生产聚丙烯薄膜或管制成，然后将其切成非常薄的（但具有非常高的截面长宽比）的带状纤维。 这样的纤维（因此初始的膜和/或管）需要存在某些化合物，其在热定型之后快速且有效地为目标聚丙烯带纤维提供刚性。 通常，这些化合物包括在暴露于足够的热量以熔化初始颗粒状聚合物之后和允许这样的熔体冷却时使目标聚丙烯中的聚合物晶体成核的任何结构。 在冷却期间，化合物必须在比没有成核剂的目标聚丙烯更高的温度下使聚合物晶体成核。 以这种方式，“硬化”成核剂化合物提供聚丙烯晶体生长的成核位点。 在切割初始膜和/或管时，然后将纤维暴露于足够的热量以生长结晶网络，从而将纤维保持在期望的位置。 优选的“硬化”化合物包括二亚苄基山梨醇基化合物，以及较不优选的化合物，例如苯甲酸钠，某些钠和磷酸锂盐（例如2,2'-亚甲基 - 双 - （4,6-二 - 叔丁基苯基）磷酸酯，也称为NA-11）。 制造这种本发明的带状纤维的具体方法以及由其制成的织物制品也包括在本发明内。

    Abstract: Bi-constituent fibers having a cationic dyeable nylon, usually Type 6 nylon adequately sulfonated, as the major component with an intimate melt blend of a minor amount of a polyester are dyed with an anionic dye to improve lightfastness, ozone resistance and to provide resistance to acid-type stains. The fibers may be tufted into carpets that are resistant to acid-type stains. Both components of the bi-constituent fiber may come from recycled sources so that 100% of the fiber, excluding processing additives, is based on post consumer recycled polymer.
