Multifunctionnal textile agents compositions

摘要

Multifunctional textile auxiliary (I) contains: (a) 10-60 wt.% nonionic surfactant of formula R1O-(Alkylene-O)m1- (I); (b) 10-60 wt.% of the reaction prod. of a nonionic surfactant of formula R2O-(Alkylene-O)n1- (II) and an unsatd. sulphonic or carboxylic acid or anhydride, (c) 4-20 wt.% hydrotropic additive, (d) 0-20 wt.% nonionic surfactant of formula R4O(C(Y1)HC(Y2)HO)p1(C(Y3)HC(Y4)HO)p2R5 (III), (e) 0-8 wt .% Mg carboxylate salt, (f) 0-30 wt.% complexing or sequestering agent, (g) 0-10 wt.% diol or polyol and (h) 0-60 wt.% water, components (e) - (g) always being present. In formulae, R1, R2 = 8-22C alkyl or 5-22C alkenyl; R3 = H, 1-4C alkyl, at least 6C cycloaliphatic gp., or benzyl; R4 = 9-14C alkyl; R5 = 1-8C alkyl, at least 5C cycloaliphatic gp., lower alkylphenyl or styryl; Y1-Y4 = H, Me or Et; one of the gps. in each pair Y1/Y2 and Y3/Y4 is always H; Alkylene = 2-4C alkylene; m1 = 1-40; n1 = 1-60; p1 = 4-10; p2 = 0-8. Also claimed is a process for the prodn. of (I) by reacting (1) and/or (2) with unsatd. acid or anhydride as above in presence of a catalyst to give (b), adjusting to pH 4.5 and adding the other components to give an homogeneous soln. Also claimed is a process for wetting, washing and/or bleaching fibre materials by treatment in aq. medium in the presence of (I), pref. in amts. of 0.1-60 (esp. pref. 1-20) g/l. Also claimed is fibre material treated by this process.
