Abstract

An aqueous medium containing reactive polymers, the reactive groups being N-methylol and/or etherified N-methylol groups, preferably based on methylolated, etherified or not, unsaturated carboxylic acid amides, included by polymerization, the portion of said reactive monomers being preferably 2.5 to 20% by weight, related to the total weight of the polymers, is applied to textiles by impregnation or preferably by coating in the presence of silanes and/or siloxanes containing amino groups and organometallic compounds, preferably zinc soaps and/or dialkyl-tin dicarboxylates as hardening agents, and heated at elevated temperature. A waterproof and water-repellent finish is obtained, resistant to washing and dry cleaning.
