    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: A process for forming a carpet, and the carpet formed thereby are provided. The process includes forming a thread comprising low melt fiber and high melt fiber. The thread is then heated above a temperature sufficient to melt the low melt fiber. The thread is tufted in a carpet backing to form a tufted carpet. The tufted carpet is then printed or dyed with an image. A process for forming a low melt content yarn and the yarn formed thereby are provided.

    Abstract: The tufted surface covering includes a base formed from particles of a thermosetting polymer compound mixed with a particle binding agent causing a portion of the particles to bind together to form a self supporting web. The base is tufted with a tufting material. Thermosetting vulcanized natural and/or synthetic rubber compounds are employed. The polymer layer is tufted with a tufting material and heated to a temperature of from about 110° C. to about 220° C. at an elevated pressure of up to two tons per square inch, to cause the particles to bind together at elevated temperature and pressure to anchor and seal the tufts in place. Cross-linking agents and polar polymer containing compounds may be employed as particle binding agents. In another aspect of the invention, a second layer of particles of a thermosetting polymer mixed with a particle binding agent may be joined together with the particles of the first layer at elevated temperature and pressure. A series of spaced apertures extends through the first and second layers to enable free draining of the surface covering. The lower surface of the covering includes spaced indentations to reduce the weight of the covering.
