ABSTRACT:
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.
