Abstract (en)
[origin: US4721512A] A process for aftertreating cellulosic fibre material using an aqueous liquor which comprises (A) a diquaternary ammonium salt of formula <IMAGE> (1) 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 groups, R1 and R2 are each independently of the other an aliphatic radical of 6 to 24 carbon atoms, R3 to R6 are each independently of the other lower alkyl, hydroxy-lower alkyl or lower alkoxy-lower alkyl, X1 and X2 are each oxygen or -NH-, Z1 and Z2 are each independently of the other C2-C6alkylene, and Y(-) is an anion of a strong inorganic or organic acid, and (B) a polybasic nitrogen-containing polycondensate.
