A PROCESS FOR POST-TREATING COLORATIONS WITH REACTIVE DYES ON TEXTILES MADE OF CELLULOSE FIBRES

摘要

A process for post-treating colorations with reactive dyes on textiles of cellulose fibres or mixtures of cellulose and synthetic fibres by treating the dyed textiles with aqueous mixtures containing 0.1 to 10g/l of compounds of the formula (I), in which R = C6- to C18-alkyl and X = H, Na, K or NR1R2R3R4, where R?1, R2, R3 and R4¿ = H, C¿1?- to C4-alkyl or -CH2-CH2-OH. Fast colorations are obtained and the compounds of formula (I) may be biologically removed from the waste water.
