ABSTRACT:
The present invention relates to a process for the production of textiles that are coated with polyurethane, in which the material that is to be coated is coated with two oppositely charged aqueous ionic dispersions of polyurethanes that contain no free isocyanate groups and contain covalently bonded, solubility-enhancing ionic groups, dried and optionally waterproofed. Cationic and anionic polyurethane dispersions are preferred in a weight ratio of 1:1, and are applied to the textile material in a two-coat technique, wet-on-wet. In addition, the invention relates to textile material produced in this way, with improved waterproof qualities and the use of such textiles for the production of breathable, water- and wind resistant clothing, industrial textiles, and leather substitutes, all of which are permeable to water vapour.
