Process for the production of coated textiles

A process for the production of coated textiles, comprising the steps of:

• providing a textile substrate having a first side and a second side opposing the first side;
• contacting the textile substrate with an organic salt solution prior to contacting an at least part of the first side of the textile substrate with a spreadable polyurethane mechanical foam, wherein the organic salt solution comprises an organic onium salt selected from the group consisting of (chloro-hydroxyalkyl)trialkylammonium salts, trialkyl[(trialkoxysilyl)alkyl]ammonium salts, trialkylalkoxyl ammonium salts, trialkylammonium epihydrinamine salts, monoammonium salts of N,N,N′,N′-tetrakis(2-hydroxyalkyl)alkylenediamine and diammonium salts of N,N,N′,N′-tetrakis(2-hydroxyalkyl)alkylenediamine;
• contacting at least a part of the first side of the textile substrate with the spreadable polyurethane mechanical foam, wherein the polyurethane mechanical foam comprises at least one polyurethane selected from the group consisting of cationic hydrophilized polyurethane, anionic hydrophilized polyurethane and nonionic hydrophilized polyurethane;
• applying a reduced pressure to at least a part of the second side of the textile substrate opposing the first side which has been contacted with the polyurethane mechanical foam;
• and
• solidifying the polyurethane mechanical foam with which the textile substrate has been contacted.
