Abstract: A method for making a polyurethane coated fabric, the method comprising:— a) providing a fabric liner; b) applying a coating to at least part of the liner, said coating comprising a polyurethane resin and manganese ferrite dissolved in a polar aprotic solvent; c) at least partially gelling the coating with water or an aqueous solution, so that the polar aprotic solvent is extracted from the coating; d) leaching the at least partially gelled coating with water or an aqueous solution, so as to further reduce the level of the polar aprotic solvent in the coating; and e) drying and curing the coating. The coating may also contain a dark colour pigment. A composition suitable for use in the method is also provided. The method enables polyurethane coated fabric products, such as gloves, to be produced which are black or grey in colour and contain a reduced amount of residual polar aprotic solvent, such as N,N-dimethylformamide.

Abstract: Fabrics are disclosed having a liner with a polymeric coating, the coating comprising 0.25 to 8 ridges per cm and pits at an area density of 20 to 2500 cm2. The fabrics provide good friction in oily conditions. Also dis-closed are methods for producing such fabrics comprising applying to a liner a liquid comprising water and a precursor of a polymeric material, contacting the liquid on the liner with a water-sorbing material and curing the polymeric coating. The fabrics may fmd use in gloves.
