METHOD FOR TREATING SOLVENT-SPUN CELLULOSE FIBERS
The invention relates to a method for treating solvent-spun cellulose fibers during which the fibers are brought into contact with a textile auxiliary in an alkaline medium. The inventive method is characterized in that a compound of general formula (I) or a salt thereof is used as the textile auxiliary, whereby: R1 is a binding link selected from the group consisting of a linear or branched chain with 1 to 4 C atoms and phenyl; R2 and R3 are identical or different from one another and are selected from the group consisting of (CH2)m-CH=CH2 with m ranging from 0 to 2, and; R4 represents an ionic group and/or a group that can be ionized in the alkaline medium.
