Coated, flexible flat material

Abstract

This invention relates to grained, textile flat materials coated with PU systems and to a process for the production thereof and to the use of such flat materials as a decorative starting material.

1 . A process for the production of grained flat materials comprising coating a textile flat material, which has residual shrinkage, with a polyurethane (PU) dispersion or solution and then post-treating the textile flat material under the influence of heat.  
     
     
         2 . The process of  claim 1  wherein the textile flat material is coating step comprises the direct process or the reversal process.  
     
     
         3 . The process of  claim 1  further comprising, prior to PU coating, stabilizing the textile flat material by aqueous coagulation with a reactive and post-crosslinkable PU dispersion.  
     
     
         4 . The process of  claim 1  further comprising, after PU coating, pre-embossing the textile flat material.  
     
     
         5 . The process of  claim 1  wherein post-treating comprises dyeing or treating the flat material tensionless with hot water.  
     
     
         6 . A grained, coated flat material obtained by the process of  claim 1 .  
     
     
         7 . A decorative starting material containing a grained, coated flat material obtained by the process of  claim 1 .  
     
     
         8 . The decorative starting material of  claim 7 , wherein the material is selected from the group of outer clothing material, material for shoe uppers, material for shoe linings, material for purses and similar articles, material for upholstery and material for automotive interior trim.
