    Abstract: Reactive geocomposite mats, and their method of manufacture, for treating contaminants in soil or water that allow the passage of essentially non-contaminated water therethrough. The geocomposite mat includes a pre-formed woven or non-woven geotextile, having a thickness of about 6 mm to about 200 mm, and having, a porosity sufficient to receive a powdered or granular contaminant-reactive material, contaminant-sorptive material, or a contaminant-neutralizing material (hereinafter collectively referred to as “contaminant-reactant material” or “contaminant-reactive material”) throughout its thickness, or in any portion of the thickness across its entire major surface(s). The powdered or granular contaminant-reactive material is disposed within the pores of the previously formed, high loft geotextile mat to surround the fibers, e.g., by vacuum or vibrating the high loft mat while in contact with the contaminant-reactive material to allow the powdered or granular contaminant-reactive material to flow by gravity into the pores of the previously formed geotextile and vibrational forces. Liquid-permeable cover sheets are adhered to the upper and lower major surfaces of the filled geotextile to prevent the powdered or granular material from escaping from the geotextile during transportation and installation.

    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 “rigidifying” 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 “rigidifying” 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 2,2′-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: A carpet in tile or roll form is produced using an open mesh reinforced foam layer with foam nodules. The carpet is produced having a primary backing through which carpet fiber bundles are tufted and a precoat layer which locks the tufts in place to prevent easy extraction of the fibers so that a tufted face and a relatively smooth back face are provided. The foam layer with foam nodules is brought into intimate contact with the relatively smooth back face, and is substantially permanently adhered to it producing a carpet tile or roll that is substantially prevented from curling or doming (or they are significantly reduced) and may be installed without adhesive if desired. Adhering may be practiced by using a non-fused adhesive formulation which is subsequently fused at a low temperature (about 310null F. or less), or by forcing the foam layer with foam nodules into contact with the carpet back while the hot melt backing is still in a fluid form, or by use of a thermoplastic layer between the carpet and foam sheet.
