Patent abstract
An aqueous sericin solution and a polar organic solvent are mixed together to prepare a sericin-containing solution, then the sericin-containing solution is added into a synthetic resin solution, followed by drying, to produce an synthetic leather wherein sericin is present as discrete particles of not larger than 3 μm in diameter within the synthetic resin of a skin layer almost uniformly at least 1.0×106 particles per square centimeter. The skin layer of the synthetic leather has a soft and moist touch like that of the natural leather and is superior in moisture absorbing and releasing properties and further superior in processing stability.
