A process is described which permits synthetic chamois pelts entirely similar to natural pelts to be obtained; the process consists in starting from any known synthetic sheet material of the type formed by a porous polyurethane matrix having synthetic fibres embedded therein and a covering skin layer of compact polyurethane resin applied to one face of the matrix, and in splitting it into two layers, a first identical to the starting material, that is provided with the matrix and the covering layer, but thinner, and a second composed only of the matrix, and in then subjecting this latter, after buffing, to a dyeing operation performed with textile technology, followed by a folding phase also typical of textile treatment, and by possible stamping and re-buffing phases.

Synthetic suede leather is produced by casting a mixture containing polyurethane elastomer and a solvent therefor between two sheets of a substrate fabric, immersing the resulting structure in a liquid which is a nonsolvent for polyurethane elastomer but miscible with said solvent, splitting said structure into two sheets at middle of the cast layer before it is fully gelled, and re-immersing the resultant sheets in said nonsolvent to allow complete gelation of said mixture.
