Abstract

Process for obtaining fibrous leather materials from mineral and/or vegetable tanned leather trim fibers and fibers of other classes, in which a suspension is prepared based on the mixture and by adding water, and by extracting the water a veil is formed, which is then dried, the product obtained being subjected to a finish and, eventually, tightening it, characterized in that leather fibers are mixed with non-leathery fibers of a length of 3 to 40 mm, the suspension is placed at a substance density of 0.1 to 0.5 g/l, and the veil thus obtained, with its own mechanical resistance, is impregnated with a binder after drying.
