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; R1 stands for hydrogen, alkyl with 1-4 carbon atoms or phenyl; R2 and R3 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.
Ce procédé de traitement de fibres de cellulose du type lyocell, selon lequel on met les fibres en contact avec un adjuvant textile, se caractérise en ce que l'on utilise comme adjuvant textile un composé de formule générale (I) ou son sel alcalin. Dans la formule, X désigne halogène, alcoxy avec 1 à 4 atomes de carbone, amino, alkylamino avec 1 à 4 atomes de carbone, hydroxysulfonyle ou 1-nicotinyle; Y répond à la formule générale (II), dans laquelle n vaut 1 ou 2; R?1¿ désigne hydrogène, alkyle avec 1 à 4 atomes de carbone ou phényle; R?2¿ et R?3¿ désignent hydrogène, hydroxysulfonyle, hydroxyle, halogène, alkyle avec 1 à 4 atomes de carbone ou carboxyle; A désigne vinyle ou -C¿2?H¿4?B, où B est un groupe clivable en conditions alcalines; et Z est égal à Y ou X.
