Abstract

644,855. Artificial leather. SERAPHIM, J. Aug. 28, 1946, No. 25772. Convention date, May 15, 1940. [Classes 96 and 140] Artificial leather or hide is produced by treating leather waste with rubber latex containing also aluminium sulphate, sodium hyposulphite, casein, an organic acid and ammonia in the proportions of 15 to 30 kilograms leather to 6 to 15 kilograms rubber latex containing 60 per cent of solid ingredients in a solution of 100 to 300 litres of water. The proportions of the solid ingredients in the solution are 1.5 to 4 kilograms sodium hyposulphite, 0.3 to 0.5 kilograms casein, 0.15 to 0.40 kilograms acid (e.g. oxalic acid), 1.3 to 4 kilograms aluminium sulphate and 500 to 1000 cc. of ammonia. The solution is mixed with the leather scrap, kneaded and allowed to stand, while the water drains away, and then compressed and dried.
