Abstract
A composite fabric comprises a layer of pile-forming material such as a textile bonded to a substrate material by an interlayer of plastics material which is substantially air-free. The interlayer has a density in the range 0.9 to 1.5 gm/cc and the substrate is a slab of deaerated plastics material having a weight up to 6.5 kg/sq. meter (12 lbs/sq. yard) and incorporating a layer of fibrous material such as glass fibre scrim. The pile forming material may be as light as 68 gm/sq. meter (2 oz/sq. yard) and as heavy as 4 kgm/sq. meter (120 oz/sq. yard).
