Process of Manufacturing a Substitute for Leather.

2633. Wagner, E. Feb. 26, 1914, [Convention date]. Combination tanning processes; leathers prepared from albumins.-A substitute for leather is made from albumins, for example bacteria, ferment-albumin, albumen, glue, or mixtures of these, by tanning the surface with dilute mineral solutions and the interior with vegetable agents, formalin, or mixtures of the same. The vegetable or like tanning of the interior renders it pliable and tough, and the mineral tanning of the exterior makes the surface hard and wear-resisting. The mineral tanning is effected with weak solutions for a short period of time at a temperature of 20‹ C. and below, and the solution is applied by squirting, painting, atomizing, &c. The exterior may be tanned prior to or after the tanning of the interior. In carrying out the process, a foundation of fabric is soaked with the solution of albumins. Vegetable tanning-substances or formalin may be added to the solutions at the beginning or after the mineral tanning, together with media for rendering the material pliant, and with ground leather, factice, colours, castor oil, wood oil, &c. The formalin may be applied in the form of vapour. The graining of the superficially hardened layers of albumins may be performed between the mineral and the vegetable or formalin tanning. The sheet of albumins may also be treated, after hardening with the mineral agent, from the foundation side with vegetable tanning, formalin, or mixtures of the same.
