The invention relates to a process for treating solvent-spun, cellulosic fibres, wherein the fibres are contacted with a textile auxiliary agent in an alkaline environment. The process according to the invention is characterized in that a compound of the general formula
or a salt thereof, respectively, is used as the textile auxiliary agent, wherein
R
1
is a bridging link selected from the group consisting of a linear or branched chain comprising 1 to 4 C-atoms and phenyl,
R
2
and R
3
are the same or different and are selected from the group consisting of (CH
2
)
m
—CH═CH
2
with m=0 to 2, and wherein R
4
denotes a ionic group and/or a group ionizable in an alkaline environment.
该发明涉及一种处理溶剂纺织纤维的方法,其中纤维在碱性环境中与纺织助剂接触。该发明的方法的特点在于,将下列通式的化合物或其盐作为纺织助剂:其中R1为选择自由基团的桥接链,所述自由基团的桥接链由1到4个碳原子的线性或分支链和苯基组成;R2和R3相同或不同,选择自(CH2)m—CH═CH2,其中m=0到2;R4表示离子基团和/或碱性环境中可离子化的基团。
