| 摘 要： | 本文研究了分散深蓝HGL(C.I.分散蓝79)染料用木质素磺酸钠Lignosol D-30为分散剂时高温染色过程中的化学稳定性。发现在高温染色过程中存在着部分染料结构中的Br被H原子所取代的副反应其产物能上染涤纶并影响产品色译。选择低还原性分散剂、降低分散剂用量和控制染浴pH值,可保持该染料高温染色的稳定性,获得较好染色效果。

| Abstract: | The chemical stability of Disperse Navy Blue HGL (C. I. Disperse Blue 79) during the high-temperature dyeing process has been studied, when sodium lignin sulfonate (Lignosol D-30) is used as a dispersing agent. It was found that a part of the dye would undergo a secondary reaction, i. e. the bromine atoms replaced by hydrogen atoms, and the mixed products thus produced are able to dye the polyester and will accordingly change the regular color shade to some degree, an undesirable effect. Therefore, in using of a dispersing agent having reduction potential, if a good stability of the dye and a uniform shade are expected, the careful control of the proper dosage used and the pH value of the dyebath are both necessary. |
