Abstract

1,271,101. Laminated flexible sheet materials. DUNLOP HOLDINGS Ltd. 16 July, 1969 [10 July, 1968], No. 32873/68. Heading B5N. A flexible sheet material is produced by assembling a layer of non-woven fibrous material on one surface of a sheet of cellular plastics material, needle-punching the fibrous layer so that fibres are pushed through to the opposite surface of the sheet of cellular plastics material, compressing the assembly under conditions such that the sheet of cellular plastics material remains in a compressed state when the pressure is removed and providing a further compressed sheet of cellular plastics material adhered to the opposite surface of the first sheet of cellular plastics material. The further sheet of cellular plastics material may be provided on the opposite surface of the first sheet of cellular plastics material after its attachment to the fibrous material by needle-punching and the whole assembly compressed under conditions such that the sheets of cellular plastics material remain in a compressed state when the pressure is removed. The layer of fibrous material may comprise staple and/or continuous fibres of polypropylene, nylon, poly(ethylene terephthalate), viscose rayon, cotton or wool, which may be crimped and may be consolidated by needlepunching and/or impregnation with a binder prior to needling to the cellular plastics material. The two sheets of cellular plastics material which may or may not have the same characteristics, e.g. they may have different compression moduli, may be closed- or open-cellular, recticular or reticulated, and may be made from polyurethane, natural or synthetic rubber, poly (vinyl chloride), polyethylene, polypropylene or polystyrene. At least one of the cellular sheets may contain an adhesive which becomes active under the conditions of compression, or may have fibres dispersed in it. The temperature of compression is preferably such that the cellular plastics material is softened without destroying the cellular structure and the opposite surfaces of the assembly may be at different temperatures during compression. Compression may be effected using a spaced mould in a press, a continuous belt press, a converging nip or a belt and drum apparatus. An additional sheet material, e.g. a woven nylon fabric or knitted, non-woven or Arachne fabric, or non-cellular plastics sheet of acrylic polymer, nylon or a polyurethane may be adhered to the assembly before, during or after the attachment or compression process, by means of an adhesive, e.g. a rubber latex, solvent or flame treatment or needling. The compressed assembly may be impregnated with a binder, e.g. a carboxylated acrylonitrile copolymer latex, or coated with a polyacrylate, nitrocellulose or polyurethane, and one or both surfaces may be embossed. The material may be used as a leather substitute in the production of shoe-uppers, shoe linings, upholstery, clothing and handbags.
