Abstract:
A carpet composite is provided having improved static electricity characteristics which comprises: a surface layer comprised of face yarn, said face yarn being embedded into a backing layer of thermoplastic resin material into which has been incorporated a mixture of carbon black and carbon fibers in an amount sufficient to improve the static electricity characteristics of said carpet composite.
Abstract:
Fluoropolymer containing coatings are applied to substrates, preferably textile substrates, to obtain composites which are flexible and not brittle, and which exhibit a low coefficient of friction, good wear resistance and excellent release properties. This invention comprises the technique of initially coating a flexible substrate, such as glass fabric or a metal mesh, with a fluoropolymer, which serves to prevent cracking upon flexing. The precoated substrate is thereafter coated with a blend of a hard polymer and a fluoropolymer which adheres well to the pre-coated intermediate substrate. Significantly, the composites of the invention are flexible, yet possess the wear resistance of the hard polymer component as well as the frictional and release characteristics of the fluoropolymer components.

Abstract:
An improved carpet tile for commercial, industrial or home use is disclosed. The carpet tile includes a carpet pile yarn facing portion including a stiffening and stabilizing layer (e.g., glass fiber layer). The backing portion also includes a stiffening and stabilizing layer (e.g., glass fiber layer). Interposed between the facing and backing portions is a stabilizing layer of a mixture of from about 70 to about 90 weight percent non-woven glass fibers and from about 30 to about 10 weight percent of a polyester. The resulting unitary carpet tile shows surprising dimensional stability, stiffness and floor hugging properties even during periods of concentrated stress, and passes rigorous flame retardancy and smoke emission tests.
Abstract:
An improved heat and dimensionally stable carpet backing comprising crossing fiberglass yarns with each of the yarns coated with a vinyl plastisol and a substantially uniform adherable and noncompatible second coating of acrylic-acetate resin uniformly distributed over the vinyl coated yarns with the bond strength of the second coating to the vinyl coating on the yarns being less than the bond strength of the vinyl coating to the fiberglass.
Abstract:
Disclosed are methods and devices for forming a combined polyester and fiberglass mat, in which separate polyester and fiberglass layers can be formed or polyester filaments and fiberglass threads can be mixed together by a disperser to form a polyester and fiberglass web. The polyester filaments and the fiberglass threads can be dispersed by separate dispersers on a web forming belt to form separate layers of polyester filaments and fiberglass threads, or can be dispersed by a single disperser to at least, somewhat evenly disperse, the fiberglass threads and polyester filaments.
Abstract:
Provided is a carpet comprising a textile top member, which includes carpet yarns and a nonwoven primary backing that is coupled with the carpet yarns so that the primary backing structurally supports the carpet yarns. The nonwoven primary backing has a layered configuration of fibers where the average fiber diameters of the fibers in one layer differs from the average fiber diameter in the layer or layers adjacent thereto. The layers are configured to mechanically reinforce and stabilize the carpet yarns. A secondary backing is coupled with the textile top member via a thermoplastic material. The carpet can be a carpet tile or a carpet rug.
Abstract:
A carpet tile comprises a primary backing layer comprising a flexible substrate with fiber tufts extending through and from one surface of the substrate to define, in use, the upper wear surface of the tile. A pre-coat adhesive layer formed from an aqueous copolymer dispersion is provided on the opposite surface of the primary backing substrate to secure the fiber tufts to the substrate and a secondary adhesive layer formed from an aqueous copolymer dispersion is provided on the pre-coat adhesive layer. A fiberglass scrim is secured to the secondary adhesive layer and an outer backing or cap layer covers the fiberglass scrim.
Abstract:
A scald-resistant synthetic leather includes a silicone layer and a high-temperature resistant substrate disposed in sequence from top to bottom. A preparing method includes coating and vulcanizating a silicone slurry on the high-temperature resistant substrate, after coating the silicone slurry, sending the high-temperature resistant substrate and the silicone slurry to a drying tunnel for vulcanization to allow attachment of the silicone layer and the high-temperature resistant substrate; after the vulcanization, peeling the silicone layer and the high-temperature resistant substrate apart to obtain the scald-resistant synthetic leather; the number of processes of coating and vulcanizating is more than one, and a thickness for a single coating is 0.02-3 mm; a total thickness for coating is 0.2-0.5 mm. The silicone slurry and the high-temperature resistant substrate used in the disclosure both are environmentally friendly and harmless materials. The high-temperature resistant substrate provides a fundamental framework, and the silicone slurry is the cover.
