Abstract

820,785. Paper containing synthetic filaments; agglutinated fibrous sheet materials. PORTALS Ltd., and WILLIAMS, H. M. G. Aug. 20, 1957 [Aug. 23, 1956; Oct. 29, 1956; Aug. 1, 1957], Nos. 25844/56, 32986/56 and 24399/57. Classes 96 and 140. Paper &c. ofhigh flexibility and tearing strength is made from synthetic filaments, e.g. of nylon &c., optionally with over 10% of cellulosic fibres, e.g. wood pulp or rag fibre, a methyl methoxy derivative of nylon being applied to the paper or waterleaf, or being added to the paper pulp. The binder may be coagulated by a water-bath, or the web may be heated, e.g. to 140‹ C. in an oil bath, or it may be dried by a steam heated cylinder. The web may be coated with cellulosic fibres, or united with a waterleaf web. Surface-active material may assist dispersion, and an anti-foaming agent may be added. In modifications, the nylon filaments may be air-deposited, or formed into a lap by carding. Specification 820,786 is referred to.
