    Abstract: A process of treating a resin-impregnated microfibrous non- woven matrix, characterized in that it includes the following treatment steps: - providing a microfibrous non- woven matrix having a top surface to be treated; - preparing said top surface of said matrix by hot calendering and/or buffing; - grouting said matrix by depositing and distributing a base resin coat thereon; - performing a micro-droplet spray deposition of one or more resins, a hot drying step being carried out on said matrix between the deposition of one layer and the deposition of the next layer, preferably an oven-drying step at a temperature ranging from 80°C to 150°C, more preferably at a temperature ranging from 90°C to 110°C; - hot embossing the surface of said matrix, said embossing step being carried out by partial melting of the fibers of said matrix, to cause a permanent deformation in said fibers of said matrix; - performing a micro-droplet spray deposition to form one or more continuous protective layers of one or more resins.

    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.
