1492943 Pile fabrics IMPERIAL CHEMICAL INDUSTRIES Ltd 3 March 1975 [6 March 1974] 10044/74 Heading DIK A pile fabric is produced by interposing a thermo-plastic material between a heated surface and a backing, withdrawing the backing with the material adhered thereto to produce fibrils, cooling the fibrils and subsequently cross-linking the material. The material itself may be cross-linkable, or may contain a crosslinking agent, preferably photo-active. If only certain areas are cross-linked an embossed effect may be obtained by subsequent heat treatment. |
