Abstract

Artificial leather is prepared from disintegrated scraps and cuttings of leather made into a pulp with water and treated with rubber latex, a vulcanizing agent, and if necessary an accelerator soluble or dispersible in water being added to the pulp before the latex; the liquid is extracted immediately after addition of the latex, and coagulation is effected and vulcanization is started at this stage. The process is further characterized in that the slurry is drawn off and the vulcanizing ingredients and binder added to it continuously as distinct from the batch method. The treated fibre is collected on a sieve and dried at a temperature of from 30-80 DEG C. Tanning agents may be added to the original pulp, and if sumach is used no accelerator is needed. In an example the amount of latex employed is from 10-20 per cent of the dry fibres. Sodium chloride may be used as coagulant.
