Abstract:
A layered cushioned composite such as a carpet or carpet tile which in at least one embodiment incorporates a layer of stabilizing material and a layer of adhesive material below a primary carpet and above a layer of compressed particle, recycled and/or rebond foam or cushioning material and having special applicability to the residential market, especially the residential do-it-yourself market.
Abstract:
A secondary backing for surface coverings is disclosed which comprises at least one thermoplastic material optionally having polymeric microspheres dispersed therein. A textile substrate comprising a primary backing with textile fibers extending upwardly from the backing and forming a surface and the above-described secondary backing attached thereto is also described. Methods of making the textile substrate and the secondary backing which can be foam or hardback are also described. Also described is a resilient surface covering, such as vinyl flooring, using the secondary backing of the present invention in one or more layers.
Abstract:
A tufted carpet is made by tufting yarn through a primary backing including a first backing layer and a second backing layer. The first backing layer is formed of a woven, non-woven or plastic sheet material, or a composite of a woven or non-woven material and a plastic sheet material. The second backing layer comprises a leno weave, open weave, plastic net or plastic sheet material. The first backing layer and the second backing layer are arranged so that the first backing layer forms a first side of the primary backing and the second backing layer forms an opposite side of the primary backing. The tufts of yarn that are sewn through the primary backing are exposed on the first side of the primary backing for forming face yams, and also form a plurality of back stitches on the opposite side of the primary backing. At least a major portion of the back stitches secure the first backing layer to the second backing layer.
Abstract:
A floor covering includes a primary backing having yarns tufted through the primary backing forming wear surface portions comprised of the back stitches of the tufted yarns in conjunction with non-tufted areas of the primary backing, also forming exposed wear surfaces. Both exposed wear surfaces portions form an aesthetic design pattern whereby a low, dense broadloom or modular carpet is provided at reduced materials and costs. Preferably, the primary backing is comprised of a woven polypropylene and a secondary backing is provided with the cut or loop yarns on the back side of the primary backing being fixed in place by a resin. A secondary backing formed of a composition of EVA, calcium carbonate and resin, overlaid by a woven scrim, is provided. The secondary backing may be formed of a needle-bonded synthetic fiber. Additionally, the primary backing may be formed of a non-woven material such as nylon and polyester.
Abstract:
A tufted carpet is made by tufting yarn through a primary backing of at least two layers, including a first backing layer and a second backing layer. The first backing layer is formed of a woven material, a non-woven material, or a composite of a woven or non-woven material and a plastic sheet material. The second backing layer is formed of a woven material of ribbons of polypropylene, polyethylene or combinations of polypropylene and polyethylene, a woven fiber glass material, a leno weave material, an open weave material, a plastic net or a plastic sheet material. A plurality of tufts of yarn that are sewn through the primary backing are exposed on one side of the primary backing for forming face yarns, and also form a plurality of back stitches on the opposite side of the primary backing. At least a major portion of the back stitches secure each layer of the primary backing to each other layer.
Abstract:
A lightweight, high-strength composite fabric suitable for use in carpet backing, roofing and membranes and other products which employ rugged fabrics. The composite fabric comprises a layer of nonwoven material disposed between a layer of low shrinkage warp strands and a layer of low shrinkage weft strands. The layers are stitched or knitted together and the resultant fabric may be coated with a resin or sizing to prevent slippage between the several layers of the fabric and impart a measure of stiffness to the fabric. The fabric may be manufactured in sheet or, more preferably, roll form and may be coated with materials suitable for desired end applications, e.g., bituminous material whereby the fabric may function as a ready-to-use roofing membrane or other high-strength fabric product.
Abstract:
A method for the production of a patterned glass fabric, especially for wallpaper or similar materials having a fabric woven with glass fiber yams, in which glass fiber yams are processed on a pattern-controlled Jacquard loom, a glass fiber yam with a titer between 130 tex and 150 tex, and preferably between 139 and 142 tex, being used for the warp, and a glass fiber yarn with a titer between 190 tex and 400 tex, and preferably of 215 tex, being used for the filling, the fluctuations in titer being less than ±10%, and preferably ±7%.
Abstract:
The inventive polymeric membrane has the feature that porous agglomerates of at least one powder of hydrophobic thermoplastic material, formed by influence of heat, are fixed onto at least one side of a carrier material or of a mixture of carrier materials by a mechanical anchoring in the carrier material and/or by an adhering onto the carrier material.Also a method of producing of this polymeric membrane and its use are described.
Abstract:
The present invention provides a heat-resistant, laminated conveyer belt comprising a reinforcing layer obtained by impregnating fluoroplastic into a heat-resistant fiber base cloth, drying and sintering the base cloth and a wear-resistant layer, formed on the reinforcing layer, obtained by impregnating fluoroplastic into a base cloth formed by weaving heat-resistant fiber in the form of a knit weave, drying and sintering the base cloth, and its manufacturing method.
Abstract:
A method of backing carpeting material 19 with hot-melt compositions such as atactic polypropylene (APP or bitumen (with or without additives) comprises carefully doctoring selected thicknesses of the composition to the undersurface of the material 19 with the wear surface of the material uppermost. In one arrangement (FIG. 3) this is achieved using a lick roll arrangement 20 incorporating a doctor blade, cooling the backed product at cooling zones 28, 29 and applying the material to a nip formed by rollers 21. In another arrangement (FIG. 1) this is achieved by doctor box 16 applying the composition to a carrier 13, the carpeting material 19 then being laminated at roll 21 to the layer of composition, the laminate then being cooled before being stripped from the carrier 13. In a further arrangement (FIG. 2) the carrier is in the form of sheet material 15 which is supported by endless belt 13 and which is bonded into the hot-melt composition to become an integral part thereof.
