摘要: 为了提高阴离子染料在反胶束体系中对棉织物的染色性能,本文在非离子Triton X-100反胶束体系中加入Span40制备出非离子混合反胶束体系,并以其为介质使用直接黄棕3G对棉织物进行染色,重点研究Span40对反胶束体系的饱和增溶水量、水池直径、聚集密度和电导率等结构特征以及直接染料对棉织物染色性能的影响。结果表明,当Span40含量为50%时反胶束体系的饱和增溶水量呈现最大值,反胶束体系的水池直径和聚集密度随着Span40的增加而增大,导致反胶束体系电导率降低,减小了直接染料与棉织物的静电排斥作用及其与表面活性剂对棉织物的竞争吸附作用,从而使直接黄棕3G对棉织物的吸附和染色性能得以提高。

Abstract: In order to improve the dyeing capacity of anionic dyes onto cotton fabric in reverse micelles, the nonionic mixed reverse micelles were prepared by adding Span40 in TX-100 reverse micelles. And the system was used as dyeing media for coloration of direct yellow brown 3G onto cotton fabric. The effect of Span40 on the maximum water solubilization, water diameter, packing density, conductivity and dyeing properties of reverse micelles were investigated, respectively. The results indicated that the maximum values of the maximum water solubilization were observed when the ratio of Span40 was 50%. The water diameter and packing density of reverse micelles increased with increasing the ratio of Span40, which caused the lower conductivity. The repelling force and competitive adsorption between dyes and cotton fabric were decreased with increasing ratio of Span40, and the higher adsorption and dyeing properties in reverse micelles were obtained.
