    • Fiber material composed of acid-modified homopolymers or copolymers of acrylonitrile (PAC fibers) which has been obtained by a wet spinning process, has not been dried and is still in a swollen condition (gel form), can be dyed advantageously and in fast colors by means of soluble dyes, the molecule of which contains several groups, namely more than one quaternary grouping and/or a strongly basic grouping carrying no charge, which exert a basic action towards the acid groups of the fiber substance. The chromophore of this colorant can belong to the category of monoazo or diazo dyes, methine, azamethine or diazamethine dyes or naphthalactam dyes.In accordance with the invention, after substantially removing the non-aqueous spinning solvent by washing, the spun material, as a moist gel, is dyed continuously or discontinuously from an aqueous dyebath; the fibers can be stretched before the dye is applied, during the dyeing process itself or immediately afterwards.By virtue of their special nature, the dyes of the type designated above, which have a strong fixing action, produce optimum fixing rates when dyeing PAC gels and, in the subsequent production stages, do not cause any noticeable soiling, as a result of dye which has bled out, on components of machines and operating baths, such as stretching or after-treatment baths. Investigations of penetration of the fiber by the dye, of the fixing rate and of the resulting fastness properties, such as fastness to wet processing, have shown no disadvantages compared with conventional dyes.
    • 由湿法纺丝法得到的酸改性均聚物或丙烯腈共聚物(PAC纤维)所组成的纤维材料未经干燥,仍处于溶胀状态(凝胶形式),可以有利地以快速染色 通过可溶性染料,其分子含有几个基团,即多于一个四元组和/或不带电荷的强碱基,其对纤维物质的酸基发挥基本作用。 这种着色剂的发色团可以属于单偶氮或重氮染料,次甲基,氮杂酮或二氮杂吗啉染料或萘胺染料。 根据本发明,通过洗涤基本上除去非水性纺丝溶剂后,作为湿凝胶的纺丝材料从水性染浴中连续或不连续地染色; 在染色过程本身之前或之后,纤维可以在施加染料之前被拉伸。 由于其特殊性质,具有强固定作用的上述类型的染料在染色PAC凝胶时产生最佳定影率,并且在随后的生产阶段中不会引起明显的污染,因为染料 已经排出了机器和操作浴的部件,如拉伸或后处理浴。 通过染料对纤维的渗透性,定影率和所得到的坚牢度性能的研究,例如湿法加工的坚牢度,与常规染料相比,没有显示出缺点。
