| abstract |
The invention relates to a method for coating textiles and/or leather, characterised in that at least one polyurethane urea that is dissolved in a solvent or solvent mixture is applied, wherein the solvent consists exclusively of one or more monohydroxy-functional alcohols, or a solvent mixture consisting exclusively of organic solvents, containing > 80 wt.% of at least one monohydroxy-functional alcohol in relation to the total mass of the solvent mixture is used, and wherein the polyurethane urea is formed by: a) at least one araliphatic, aliphatic and/or cycloaliphatic diisocyanate; b) at least one polyether polyol having a number average molecular weight Mn ≥ 400 and ≤ 6000 g/mol and an average hydroxyl functionality of ≥ 1.5 and ≤ 4; c) at least one amino-functional compound having at least two isocyanate reactive amino groups; and optionally other components. The invention also relates to a textile or leather coating produced using this method and a dissolved polyurethane urea, and to the use of the polyurethane urea for coating substrates and for producing free films. |
