Abstract
1,200,662. Composite materials. DUNLOP CO. Ltd. 15 March, 1968 [21 March, 1967], No. 13077/67. Addition to 1,039,861. Headings C3C and C3R. [Also in Division D1] Composite materials are prepared by introducing into an assembly of fibres first a liquid composition which is one part of a polyurethane foam-forming mixture and subsequently a vapour which is the complementary part of the polyurethane foam-forming mixture, and allowing the liquid composition and vapour to react to form a polyurethane foam within the assembly of fibres, the polyurethane foam being hydrophilic. The liquid composition suitably contains a polyurethane prepolymer which is based on at least 10% by weight of polyethylene ether glycol to ensure the hydrophilic nature of the resulting foam. The vapour may comprise an amine catalyst or preferably steam. In examples, the assembly of fibres is in the form of a fibrous web prepared from viscose rayon staple fibres by cross-lapping a carded web of the fibres and a web of crimped nylon monofilaments. The fibrous assemblies may be compressed or moulded during or after foaming. An assembly of fibres may comprise two fibrous webs superimposed one upon the other, and the structure obtained when the polyurethane foam-forming reaction has taken place may then be separated into two layers corresponding to the original two webs, the layers obtained being treated again individually in accordance with the invention. The fibres may also be moulded during foaming between an impervious surface and a porous surface.
