Abstract:
A novel carpet tile is provided with a polyurethane adhesive layer resulting in a lightweight product with exceptional dimensional stability.
Abstract:
The carpet tile system uses preferably Aluminum Hydroxide (Al(OH)3) as a flame retardant in the secondary backing of the carpet tile or in the pre-coat adhesive on the primary backing, or alternatively uses Magnesium Hydroxide (Mg(OH)2). The flame retardant has been optimized to interact with the other components of the system to produce a carpet tile that achieves flammability ratings that are comparable or superior to carpet tiles with more expensive pile fibers.
Abstract:
The invention provides a sheet-like article including: a fibrous base including ultrafine fibers; and a polyurethane resin as a binder to the fibrous base, wherein the polyurethane resin includes a polymer polyol-derived structure that includes a polycarbonate polyol-derived structure, and the polyurethane resin satisfies the following (I), (II) and (III) or (IV): (I) the polyurethane resin includes a carbonate bond, and an ether bond and/or an ester bond in the molecule; (II) the total content of urethane group and urea group in the polyurethane resin is 7 to 11% by mass; and (III) 80 to 100% by mass of a polycarbonate polyol yielding the polycarbonate polyol-derived structure is a polycarbonate polyol having a melting point of 20° C. or lower; or (IV) 80 to 100% by mass of a polycarbonate polyol yielding the polycarbonate polyol-derived structure is a polycarbonate polyol copolymerized with two or more polyhydric alcohols having different carbon skeletons.
Abstract:
The present invention pertains to carpet and method of making it. In one aspect, the carpet includes (a) a primary backing which has a face and a back surface, (b) a plurality of fibers attached to the primary backing and extending from the face of the primary backing and exposed at the back surface of the primary backing, (c) an adhesive backing, (d) an optional secondary backing adjacent to the adhesive backing, and (e) at least one homogeneously branched linear ethylene polymer. The method includes extrusion coating at least one homogeneously branched linear ethylene polymer onto the back surface of a primary backing to provide an adhesive backing. The method can include additional steps or procedures, either separately or in various combinations. Additional steps and procedures include preheating the primary backing prior the extrusion step, multilayer adhesive backings, washing or scouring the primary backing prior the extrusion step, and utilizing adhesive polymeric additives, high heat content fillers, blowing agents and/or implosion agents. The constructions and methods described herein are particularly suited for making carpet tile.
Abstract:
A damping layer comprises a large number of yarns combined to form a textile, wherein at least some of the yarns are foamed synthetic yarns. Such a textile, which consists of a mix of foamed and non-foamed synthetic yarns, is relatively strong and light and can lead to more efficient use of the foamed material. The foamed synthetic yarn may be formed into upstanding loops which provide additional resiliency and damping.
Abstract:
A system for covering (i.e., closing) various types of sites where waste is deposited comprises a composite of one or more geotextiles that are tufted with synthetic yarns and an impermeable geomembrane, which is comprised of a polymeric material. The geotextiles can comprise polypropylene or polyethylene. The cover can include wind-resistant textured synthetic blade-like elements, such as vertical filaments, secured over a low-permeable polymer liner backing. Advantageously, the system does not rely on piled-on weight to resist wind forces and the cover can be deployed over a large area with little or no ballasting or anchoring. Optionally, the cover includes vertical filaments attached to the liner to break the wind aero-dynamics on the exposed cover. With this system, it is believed that the wind velocity on the impermeable surface (membrane) now becomes turbulent near the surface of the cover, thus greatly reducing the actual wind velocity at the liner surface and decreasing associated uplift.

Abstract:
A roofing underlayment having a slip-resistant surface includes a woven polypropylene scrim laminated to a top layer made from a non-woven spun-bond polypropylene fabric. During lamination, the scrim is bonded to the top layer by a polypropylene coating that impregnates the scrim, thereby forming a structural bottom layer comprising the polypropylene-impregnated scrim. The non-woven fibers of the top layer provide a micro-textured, slip-resistant surface. A second polypropylene coating may be applied to the bottom surface of the bottom structural layer. An adhesive layer may optionally be applied either to the bottom surface of the bottom structural layer, or, if used, to the bottom surface of the second polypropylene coating.
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.
