ABSTRACT:
The present invention relates to a process for obtaining wash- and cleaning-resistant textile finishes by impregnating with customary reactive perfluoroalkyl-containing (co)polymers and/or precondensates in aqueous dispersion and concluding heating, wherein the dispersions have NCO-containing compounds which have a molecular weight of at least 450 and/or contain a diphenylmethane-based polyisocyanate mixture in blocked form.
The process according to the invention has made it possible to equip textiles with water-repellant and oil-repellant finishes which are very highly wash- and cleaning-resistant.
