Abstract: 1332086 Laminated foam lined fabric BURLINGTON INDUSTRIES Inc 17 Feb 1972 [24 Feb 1971 (2)] 7439/72 Heading B5N [Also in Divisions B2 and D1] A method of making a lined textile fabric comprises the steps of applying to one face of a textile fabric, either a foamed organic polymeric material or a foamable organic polymeric material which is subsequently foamed, to form an at least partial foam lining on the one face of the textile fabric, applying to the organic polymeric material, whilst the organic polymeric material is in a softened or uncured state, either a spun-laced non-woven backing fabric or a bonded non-woven backing fabric wherein most of the individual fibres are adhered to one another by an adhesive or by fibre-fusion, and hardening or curing the organic polymeric material to adhere the backing fabric to the textile fabric. A finish resin may be applied either to the exposed surface of the textile fabric or to the two surfaces of the lined textile fabric. The textile fabric may be a woven or knitted fabric, a non-woven fabric, a lace or a sewn fabric and may be made from fibres or filaments of cotton, wool, sisal, jute, linen, silk, regenerated cellulose, polynosic rayon, cellulose acetate, cellulose acetate-butyrate, cellulose acetate-propionate, cellulose triacetate, polyacrylonitrile, an acrylonitrile-vinyl chloride copolymer, polyvinylidene chloride, a vinylidene chloride-vinyl chloride copolymer, nylon, polyethylene, polypropylene, polyester, rubber, synthetic rubber or glass and blends thereof. The foamed polymeric material which is preferably foamed in situ may comprise rubber, polyurethane, polystyrene, polyvinyl chloride, polyethylene, a phenol-formaldehyde resin, a urea-formaldehyde resin, a melamine-formaldehyde resin, a silicone, cellulose acetate or a crosslinked copolymer of styrene and acrylic acid and may contain opacifying pigments or dyes. The spun-laced non-woven backing fabric is defined as being " a textile fabric consisting of fibres entangled in a predetermined repeating pattern to form a strong unbonded structure having a tensile strength greater than one pound /inch/ounce//yard<SP>2</SP>, and may be formed from staple or other fibres of polyesters, cotton, viscose, cellulose acetate, cellulose acetatebutyrate, cellulose acetate-propionate, polyacrylonitrile, polyvinylidene chloride, a vinylidene. chloride-vinyl chloride copolymer, polypropylene, polyethylene, nylon, wool, silk or polypivalolactone or blends thereof. The bonded non-woven backing fabric may be made from fibres or filaments of jute, cotton, wool, hemp, polyethylene terephthalate, polyacrylonitrile, polyvinylidene chloride, a vinylidene chloride-vinyl chloride copolymer, polyethylene, polyvinyl chloride, polypropylene or a modacrylic resin. Bonding of the fibres may be effected by an adhesive, e.g. polyethylene or a melamine - formaldehyde, urea - formaldehyde, phenol-formaldehyde, resorcinol, formaldehyde, epoxy or acrylic resin: alternatively, when at least some of the fibres are thermoplastic, bonding may be effected by the application of heat and pressure. The method of the invention is preferably effected continuously, the backing fabric being applied before or after gellation of the polymeric material, the surface of the foam in the latter case being softened either by the application of a solvent or a flame prior to application of the backing fabric. In a preferred embodiment, the foam layer is crushed, e.g. by passing the composite fabric through rollers prior to passing it through a padding bath to apply a finishing resin, e.g. a durable crease cross-linking resin thereto. Specified finishing resins are eondensates of aldehydes or ketones, e.g. formaldehyde, acetaldehyde, acetone or methyl ethyl ketone with urea, thiourea, cyanamide, dicyandiamide, cyclic ethylene urea, biguanide, melamine, formamide, formoguanamine, ethyl carbamate, acetoguanamine or a biazone.
