<p>A fabric structure 1 comprises a nylon or polyester fabric base sheet 10, a viscidity layer 20, a polymeric back layer 30 and a protective layer 40. Layers 20 and 30 comprise a styrene based block copolymer blended with other additives, eg. viscosity modifiers, processing oils and methyl ethyl ketone. Layer 40 comprises a polyurethane resin or a modified styrenic block copolymer. The composite structure is assembled either by sequential extrusion and curing of layers 20 and 30, on base sheet 10, or by co-extrusion of layers 20 and 30 and subsequent lamination to base sheet 10 through a roller nip. In either case protective layer 40 is coated onto the resultant structure, in the final stage of the process. In use the fabric structure is used to make sports bags and similar articles, the fabric base being disposed outside the bag and the protective layer being disposed inside the bag. The fabric is stated to overcome pollution drawbacks of similar prior art fabrics employing polyvinylchloride.</p> |
