Abstract:
A method for the combined preparation of a tufted and a bonded carpet material which method comprises bonding the top surface of a fibrous, tufted face surface of the tufted carpet material to a layer of an adhesive material secured to a backing layer to form a sandwich-type material, and splitting the sandwich-type material to provide for tufted carpet material and a bonded carpet material, each having a severed, fibrous face wear surface.
Abstract:
A method to impart permanent stain resistance to polyamides, including nylon fiber and fibrous articles such as carpet and carpet tile, that includes treating the fiber with an isocyanate under moderate conditions that do not damage other materials that the fiber is attached to. Nylon carpet and carpet tile treated according to this method are highly suited for commercial use because they retain their stain resistance after repeated washings.
Abstract:
A fusion bonded carpet (199) with a latex formulation pile yarn backing adhesive (36) which includes vinyl acetate-ethylene, ethylene-vinylacetate, styrenebutadiene, latex polyvinyl chloride, polyvinylidene chloride, vinyl acetate acrylic acid or ester, styrene acrylic acid or ester, acrylic or methacrylic acid and their esters, or copolymers of these compounds.
Abstract:
The present invention comprises a dish-shaped cabinet skate (20) made of an ultra high molecular weight polyethylene, which is applied to furniture feet (10). The skate (20) is adapted to be affixed in a permanent or semi-permanent manner on standard office furniture feet (10). The skate (20) has an inherently low coefficient of friction with respect to conventional carpeting, thus allowing easy sliding. The skate (20) is shaped to include large radius bends at the edges and a slight crowning (32) of the bottom surface to further reduce resistance to sliding.
Abstract:
A pattern-tufted, fusion-bonded carpet, particularly a backed carpet tile, having a polymeric latex primary adhesive layer and a plurality of fibrous yarns bonded to and extending from the layer to form a face surface, the fusion-bonded carpet having a woven polyester sheet material and glass fiber tissue sheet material both secured to the primary adhesive base layer, and the fusion-bonded carpet overtufted by an overtufted pattern on the face wear surface. A method of preparing a pattern-tufted, fusion-bonded carpet which comprises overtufting a fusion-bonded carpet with the fusion-bonded carpet having a primary adhesive base layer composed of a polymeric latex material and containing a woven fiberglass sheet and a glass fiber tissue sheet material and optionally to prepare carpet tile applying a solid, thermoplastic backing to the pattern-tufted, fusion-bonded carpet material.
Abstract:
A carpet and carpet tile resistant to the growth of Gram negative, Gram positive and fungal organisms which contains a poleric non-plasticized PVC tuftlock precoat, fusion bonding adhesive, or secondary backing which has incorporated in it a phosphoric acid ester or its salt of general formula (I), wherein R and R' are alkyl, oxyalkyl, polyoxyalkyl, aryl, aralkyl or alkaryl groups of C1 to C24, and one of R or R' can be H; X is a Group I metal ion, Group II metal ion, transition metal ion, or NY1Y2Y3Y4, where Y1-4 are hydrogen, a hydrocarbon of C1 to C24, or a hydroxyalkyl group of C1 to C24; and there is at least one free hydroxyl group; and when X is NY1Y2Y3Y4 or a Group I metal ion, n is 1, when X is a Group II metal ion, n is 2; and when X is a transition metal, n is equal to the valence of the metal.
Abstract:
A composition for imparting stain resistance to polyamide substrates comprising a sulfonated fatty composition and sulfonated hydroxyaromatic formaldehyde condensation polymer. A method for making the stain treatment composition, a method for treating polyamide substrates with the composition, and the resulting stain resistance polyamide materials are also disclosed. Suitable sulfonated hydroxyaromatic formaldehyde condensation polymers include sulfonated phenol formaldehyde condensation polymer and sulfonated dihydroxy diphenyl formaldehyde condensate polymer. Suitable sulfonated fatty compositions include sulfonated oleic acid and marine oil.
Abstract:
Processes for tufting substrate or primary carpet backing (111) using conventional double needle bars (116, 112) but in which the needles may be shifted less than a full gauge. Processes of the present invention may employ a conventional double needle bar tufting machine (133) to which is added means for shifting or indexing the hook bar (134) laterally to the machine direction of the substrate being tufted. Timing of shifting of the hook bar (134) may be coordinated with timing of shifting of the needle bar (133) and advance of the substrate (111) through the machine to allow piles (132) to be tufted into the substrate (111) at any desired lateral position with respect to previously tufted piles. The invention creates additional pile color pattern alternatives and eliminates repetitive patterns otherwise necessitated by full gauge shifting. Elimination of repeat color sequences reduces matching color sequences on adjoining edges of adjacent carpet tiles made from such substrate which otherwise accentuate or highlight the seams between carpet tiles.
Abstract:
Electrically conductive and static dissipative materials (14), and methods of manufacturing the materials, are disclosed. Unlike existing conductive films or webs, the present invention includes discrete electrically conductive fibers (62) dispensed to form a network principally at or near the surface of a polyvinyl chloride (PVC) or other substrate (58). The fibers are typically, but need not be, copper sulfide dyed acrylics. Forming such a conductive network in situ permits the resulting material to have improved electrical characteristics.
Abstract:
A biocidal protective coating and a method for coating heat exchanger coils, which includes a polymeric composition comprising an organic water resistant polymer and a compound of general formula (I), wherein X is selected from the group consisting of organic ions, H , Group I metals, Group II metals and transition metals, R and R' are independently selected from the group consisting of hydrocarbons and substituted hydrocarbons of not more than 24 carbon atoms, and there is at least one free hydroxyl group.
