Abstract
Abstract An assistant combination for use as textile finishing agent, especially in a process for aftertreating wool dyeings, which comprises (1) a diquaternary ammonium salt of formula ##STR1## wherein Q is a divalent aliphatic hydrocarbon radical of 2 to 12 carbon atoms which may be interrupted in the chain by oxygen atoms and is unsubstituted or substituted by hydroxy. R 1 and R 2 are each independently of the other an aliphatic radical of 6 to 24 carbon atoms, R 3 to R 6 are independently of the other lower alkyl, hydroxy-lower alkyl or lower alkoxy-lower alkyl, X 1 and X 2 are each oxygen or --NH--, Z 1 and Z 2 are each independently of the other C 2 -C 6 alkylene, and Y.sup.⊖ is an anion of a strong inorganic or organic acid, and (2) (A) a mono- or polyquaternary ammonium salt which carries at least one hydrocarbon radical of not less than 7 carbon atoms attached to the nitrogen atom, or (B) a polymeric ammonium salt, or (C) a basic non-quaternized nitrogen-containing polycondensate.
