ABSTRACT:
The invention relates to a method for coating sheet-form textile materials, in which there is applied to a sheet-form textile material an aqueous dispersion containing anionically modified polyurethane ureas comprising (A) aromatic diisocyanate, (B) polyether polyol having a mean molecular weight greater than 1500, (C) at least one compound containing from 1 to 2 isocyanate-reactive groups and at least one ionogenic group, (D) polyamine having a mean molecular weight of at least 32, and (E) water, wherein the mean total functionality of the isocyanate-reactive compounds B to D is from 1.85 to 2.2, the molar ratio of the isocyanate groups of component A to the isocyanate-reactive groups of components B to D is greater than 1, and the polyurethane ureas have a content of from 800 to 1500 mmol of urethane groups/kg of anionically modified polyurethane urea and a content of from 800 to 1800 mmol of urethane plus urea groups/kg of anionically modified polyurethane urea.
