Abstract:
A non-woven fabric reinforced microporous polymer membrane for nonaqueous electrolyte batteries or capacitor and manufacturing method thereof. The polymer latex is prepared by copolymerizing water soluble polymer 100 parts, hydrophobic monomer 30-500 parts, hydrophilic monomer 0-200 parts and initiator 1-5 parts. According to 100% solids content of the polymer latex, adding 0-100% inorganic fillers and 20-100% plasticizers, and the paste is obtained. The two surface of the non-woven fabric are coated with the paste, drying, and the non-woven fabric reinforced microporous polymer membrane is obtained.
Abstract:
A tufted fabric that incorporates an odor-receiving layer to remove unwanted odors from the final product in which the fabric is incorporated, particularly in floor covering articles. In an alternative embodiment, the present invention is a needle-punched fabric that incorporates an odor-receiving layer.
Abstract:
The disclosure relates to a carpet product, a process for manufacturing carpet, and an apparatus used in a carpet manufacturing process. The carpet product is made from tufted polymer filament yarn wherein the individual yarn filaments of the yarn back loops are integrally fused so that the carpet resists fuzzing. The primary backing preferably is modified polypropylene in the fill direction. Further, the primary backing may be coated with a polymer before tufting to adhere or integrally fuse the inside of the fiber tuft to the primary backing. An optional secondary backing is preferably made of tape yarn in both directions. The process includes providing a carpet base having a primary backing penetrated by yarn, applying heat to the underside of the primary backing, extruding a heated sheet of polymer and continuously contacting the heated extruded sheet of polymer with the base. The apparatus includes a source of carpet precursor, a heated cylinder for heating the underside of the carpet, and extruder and a casting roll against which the extruded sheet and heated carpet are pressed.
Abstract:
A tufted mat is described having high absorbency for water and oil, minimizing the return and outflow of absorbed fluids, and showing little dirt on its surface. The mat includes a sheet-shaped base and multiple piles embedded in the base from the back side of the base and tufted on the surface side of the base and characterized in that each of the piles comprise a bundle of synthetic single yarns each with a fineness of 10 denier or less. Preferably, the pile height on the surface side of the mat is 5 mm or less.
Abstract:
A composite floor covering having an upper layer (1) of a decorative fabric, a dimensionally stabilizing intermediate layer (3), and an optional lower cushioning layer (5) has at least the upper surface of the decorative fabric coated with a protective polymeric coating in a manner such that the hand of the decorative fabric layer is substantially retained. The materials of the fabric layer, stabilizing layer, and cushioning layer (if provided) as well as the form of attachment therebetween, cooperate to render the floor covering substantially impervious to liquid.
Abstract:
A tufted carpet or mat product comprises a primary support fabric having an underside and an upper side, a layer of rubber or synthetic rubber adhered e.g. by vulcanization to the underside of the primary support fabric, and yarn nops extending through the primary support fabric for forming of a nap on the upper side of the primary support fabric and for forming of nap nop bottom parts between the rubber layer and the primary support fabric. In said tufted product the nap comprises 70-95, preferably 80 weight per cent animal wool and 5-30, preferably 20 weight per cent synthetic fibers, such as fibers of acryl, fluorocarbons, polyacetales, polyamides, polyesters, polyethylenes, polypropylenes, polyurethanes and similar fibers being relatively fire inhibiting, the primary support fabric material consists of fibers which per se has a high ignition point, and the rubber layer has been selected from the group of washable rubbers not being fire supporting and which preferably also are resistant against oils, gasoline, acids and bases. Thereby a tufted product is achieved which has a hitherto unknown self-extinguishing or fire inhibiting effect and which is washable after use and dirt and water binding during use.
Abstract:
A method for binding a greige carpet and a secondary backing material using a hot melt adhesive is disclosed. A heated application roll may be provided and the secondary backing material may be contacted with the hot melt adhesive and greige carpet and pressed against the heated application roll.
Abstract:
Polymeric carpet and a method of making and recycling such carpet, the carpet having fibers, backing and extruded adhesive all of completely recyclable materials, the recycling being accomplished in one melting step, without a separation step.
