Abstract:
The invention relates to the use of mixtures that contain an aqueous dispersion of a vinyl acetate polymer and an aqueous dispersion of a vinyl acetate-ethylene copolymer for carpet coating compositions, and corresponding carpet coating compositions, as well as carpets which are coated with such carpet coating compositions.
Abstract:
Polyamide terpolymer compositions, which contain biobased monomers and are suitable for making shaped articles, are disclosed. Comprised of three monomeric species polymerized randomly, including hexamethylene diamine, adipic acid and a bio-based monomer, the compositions are easier to process and have better dye uniformity than polyamides formed from melt-blended biobased components, and are comparable in dyeability, color fastnessand appearance retention performance to non-biobased polyamide copolymers.
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.

Embodiments of the present disclosure include flame retardant composites, flame retardant nylon fibers, flame retardant nylon fiber carpets, methods of making each, and the like.
Abstract:
A process for making a Drylon rug is disclosed, wherein the said process comprises use of dope dyed, micro-denier filament, cabled and heat set polyester yarn or micro denier filament, cabled heat set dyed with antimicrobial treatment for tufting of rugs, thereby eliminating the process of batch dyeing after the formation of rugs and further ensuring that the rugs are bleach safe, quick drying, anti microbial and stain resistant. The present invention also discloses Drylon rugs as manufactured using yarns of invention. Further, the present invention discloses the process for manufacture of Drylon yarns.
Abstract:
An artificial turf is formed of grass fibers, a grass bottom and a rear glue. The grass fibers and the grass bottom are both made from polyethylene, polypropylene and/or polyamide, and the rear glue is mainly made from ethylene-vinyl acetate copolymer emulsion with filler and antioxidant, etc. The artificial turf is manufactured by making the rear-adhesive components into glue paste and coating it on the rear of the grass bottom fixed with grass fibers.
Abstract:
A material having a woven layer and a nonwoven layer needled together. The woven layer contains a plurality of interwoven polypropylene tape elements and the nonwoven layer contains a plurality of intermingled polyester fiber elements.
Abstract:
A tufted carpet includes a primary backing and a plurality of tufts. The plurality of tufts are attached to the primary backing by looping each yarn tuft through different openings of the primary backing with strand sections from adjacent tufts going through each opening. The tufted carpet further includes an adhesive or polymeric material contacting the tufts such that the tufts are bonded together. A system and method for forming the tufted carpets is also provided.
Abstract:
The application discloses coherent, processable rubber compositions containing cured rubber particles, especially recycled crumb rubber, dispersed in a curable base rubber. A processable composition, particularly one which can be roll-processed into a self-sustaining web is achieved by including in the curable rubber a low-viscosity curable rubber component such as a liquid rubber. This component wets the crumb rubber enabling it to disperse fully during mixing and connect intimately into the structure upon curing. This technique enables larger quantities and/or smaller particle sizes of the crumb rubber to be successfully incorporated while maintaining processability. Inert fillers can be used or omitted, reducing density. The novel rubber compounds are particularly suitable for making into layer products such as mats and flooring materials. Desirably these are laminated with fabric such as tufted textiles. This can be done in a compression moulding process.
Abstract:
To improve the liquid barrier properties of a carpet, a repellency compound, such as a fluorochemical, is applied to the backstitch side or underside of the primary backing layer of a carpet.
