ABSTRACT:
A method of manufacturing a composite fabric comprising the steps of coating one surface of a web of relatively lightweight material with a layer of foamed plastics material in liquid state, forming a substrate material by applying a layer of fibrous material to a layer of deaerated thermo-plastics material in liquid form, maintaining the viscosity of the thermo-plastics material at a level to permit the fibrous material to sink into the layer of thermo-plastics material, thermally treating the substrate material to achieve firm gellation of the thermo-plastics material therein and applying the coated surface of the lightweight material to the substrate material when in a heated state for a period sufficient to effect gellation of the foamed plastics material to form the composite fabric.
