Abstract

1285214 Artificial leather GLANZSTOFF AG 24 Sept 1969 [17 Dec 1968] 46936/69 Heading B2E Artificial leather is prepared by coating a fibrous textile material, particularly a non- woven fleece, which has been bonded with polyurethane with a polyurethane gel containing 1-10% by weight of silicone oil based on the weight of polyurethane in the gel, coagulating the coating, washing and drying to produce a microporous covering layer on the substrate. The polyurethane gel usually contains 30-40% by weight of polyurethane and may contain stabilisers, pigments, dyes and up to 30% of polyvinyl chloride. It may be applied by means of a coating knife. The solvent used in the gel may be dimethyl formamide, dimethyl sulphoxide or dimethylacetamide. The polyurethane coating may be further coated with polyurethane and nitrocellulose lacquer.
