1341637 Laminates JOHNSON & JOHNSON 19 April 1971 [26 March 1970] 25402/71 Heading B5N A paper laminate suitable as a substitute for woven or non-woven fabrics is made by laminating at least two plys of creped tissue paper having a thickness of 2À20 mil and a basis weight 5 to 30 1bs., suitably having a machine direction stretch level of 5 to 50%, removing the crepe while impregnating with a strength imparting resin by passing the superposed plys through an aqueous suspension or emulsion of resin, reremoving water and curing the resin. The strength imparting resin is selected from polymers of ethyl acrylate and ethylhexyl acrylate and copolymers thereof with methyl methacrylate or polyvinyl acetate, styrene/butadiene copolymers, polymethylmethacrylate, urea formaldehyde and melamine resins. The impregnation may be effected by passing the laminate through the suspension containing 5 to 50% by weight of resin at a rate sufficient to contain a wet pick-up of 75 to 250%. The saturated laminate may then be dried at 240 to 350 F. for two minutes to remove water and cure the resin and provide a laminate with a resin content of 10 to 30% by weight. Softeners such as glycerine or polyethylene glycol may be incorporated. |
