Leathery sheet material and process for the preparation thereof |
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.
