    摘要: A grained artificial leather comprised of a sheet-form fibrous base, a porous polyurethane layer having interconnected open cells, formed on at least one surface of the base, and a non-porous polyurethane film formed on the porous polyurethane layer. A multiplicity of open cells are interspersed in the porous polyurethane layer, part of which are closed by the non-porous polyurethane film and the remainder of which are not closed and at least 70% in number of the non-closed opening cells have a diameter of 1-25 .mu.m.The artificial leather is made by adhering the porous polyurethane layer to the sheet-form fibrous base, applying a polyurethane/solvent mixed liquid as dots interspersed on the surface of the polyurethane layer to develop a multiplicity of open cells on the surface, and then applying a finishing polyurethane on the open cell-developed surface.

    摘要: A leathery sheet material which comprises a fibrous mat and a polyurethane composition applied all over the mat in an amount of 10 to 80% by weight based on the total weight of the mat and the polyurethane composition. The polyurethane composition contains 0.1 to 5.0% by weight of a surface active agent having a molecular weight of 2,500 to 30,000 which comprises a hydrophilic component and a hydrophobic component being combined by a urethane bond and/or an amide bond. The hydrophilic component is polyethylene oxides comprising 30 to 80% by weight of the surface active agent and the hydrophobic component is a member selected from the group consisting of a polyalkylene oxides excepting polyethylene oxides, aliphatic polyesters and mixtures thereof. The leathery sheet material has excellent flexibility, excellent antistatic properties and excellent soil resistance.
