Abstract (en)

[origin: WO9749856A1] A process for treating cellulose fibres of the lyocell type, by which the fibres are brought into contact with a textile auxiliary agent, is characterised in that a compound having the general formula (I) or its alkaline salt is used as textile auxiliary agent. In the formula, X stands for halogen, alkoxy with 1-4 carbon atoms, amino, alkylamino with 1-4 carbon atoms, hydroxysulphonyl or 1-nicotinyl; Y has the general formula (II), in which n equals 1 or 2; R<1> stands for hydrogen, alkyl with 1-4 carbon atoms or phenyl; R<2> and R<3> stand for hydrogen, hydroxysulphonyl, hydroxyl, halogen, alkyl with 1-4 carbon atoms or carboxyl; A stands for vinyl or -C2H4B, in which B is a group that can be split under alkaline conditions; and Z is equal to Y or X.
