A sulphonyl urea-containing softener and water-repellant for textiles containing cellulose and for leather, method for the preparation thereof; the sulphonyl ureas and process for their preparation

摘要

The softening and waterproofing agents for cellulose, cellulose-containing textiles and for leather consist of a part by weight of a compound RB -? - NH-SO2-X (1) in which R is alkyl or alkenyl with 10 to 30 C atoms, B is one of the divalent radicals IMAGE X is β-haloalkyl or alkenyl each having 2 to 4 carbon atoms and R¹ and R² are hydrogen or alkyl having 1 to 4 carbon atoms and n is 2, 3 or 4, and b parts by weight of an emulsifier consisting of 100-37.5% of known nonionic emulsifiers, 0-50% of known anionic emulsifiers and 0 to 25% of known lickers, c parts by weight of an epoxide IMAGE in which R³ is alkyl or alkenyl with 15 to 40 C atoms, and optionally d parts by weight Water or a water-miscible organic solvent, where a has a value from 80 to 99, b has a value from 20 to 1, c has a value from 0 to 5 and IMAGE has a value from 10 to 40. Sulfonylureas of the general formula RB -? - NH-SO2-X in which R is alkyl or alkenyl having 10 to 30 C atoms, B is one of the divalent radicals IMAGE X is β-haloalkyl or alkenyl each having 2 to C atoms and R¹ for alkyl with 1 to 4 carbon atoms, R² for hydrogen or alkyl with 1 to 4 carbon atoms and n for 2, 3 or 4, prepared by reacting a β-haloalkylsulfonyl isocyanate with 2 to 4 carbon atoms in the Alkyl radical of
