Process for producing cellulose fibres

A process for the treatment of cellulose fibers of the Lyocell type, wherein said fibers are contacted with a textile auxiliary agent, characterized in that as said textile auxiliary agent a compound of the general formula ##STR1## or its alkaline metal salt is employed, wherein X is halogen, alkoxy having 1-4 carbon atoms, amino, alkylamino having 1-4 carbon atoms, hydroxysulphonyl or 1-nicotinyl; Y having the general formula ##STR2## wherein n is the number 1 or 2; R.sup.1 is hydrogen, alkyl having 1-4 carbon atoms or phenyl; R.sup.2 and R.sup.3 are hydrogen, hydroxysulphonyl, hydroxyl, halogen, alkyl having 1-4 carbon atoms or carboxyl; A is vinyl or --C.sub.2 H.sub.4 B, wherein B is a group capable of being cleaved under alkaline conditions; and Z is Y or X.

Process for the treatment of cellulose fibres and of assemblies made

Process for the production of cellulose fibres having a reduced tendency to fibrillation, in which a solution of cellulose in a tertiary amine-oxide is spun into fibres and the freshly spun fibres are contacted with a textile agent comprising at least two reactive groups, and are heat-treated, characterized in that the heat treatment is carried out by means of irradiation with electromagnetic waves.
