本文对阳离子染料的上染特性曲线以及加入匀染剂TAN(1227)的上染特性曲线进行对比研究,合成了两种阳离子匀染剂十二烷基二甲基羟乙基氯化胺(LHAC)和十二烷基二甲基乙基溴化铵(LEAB),其匀染性能较为理想。另外,分别对阳离子匀染剂的复配物以及阳离子匀染剂与非离子匀染剂的复配物进行应用实验。结果表明,复配物的匀染性能都明显优于单独使用的阳离子匀染剂。从而为高性能阳离子匀染剂的研制和开发提供了依据。 相似文献

The compatibility of a mixture of disperse dyes in equal proportions having similar hues (all in the red-yellow quadrant of the colour space) has been assessed at different applied depths on polyester fabric, with and without levelling agent, using plots of hue angle against KIS values. The plots were found to be useful in indicating the improvement in the compatibility of dyes at higher applied depths attributable to the addition of a nonionic levelling agent. 相似文献

Temporarily solubilised disperse dyes derived from aminophenyl-4-(β-sulphatoethylsulphone) have been applied to wool fabric without the use of a levelling agent. By virtue of their characteristic dye structure, excellent levelling properties were observed on wool fabric. Good exhaustion, fixation and fastness test values were also obtained. 相似文献

The properties of an electrolyte for acid bright copper deposition have been investigated. The influence of polyaniline dispersion, polysafranine dye (levelling component), poly(alkylene oxide) (wetting agent) or dialkyl disulfides (brightener) and combinations of these additives on the quality of electrodeposited coatings were studied. The presence of polyaniline dispersions increased the levelling ability by 16% and at the same time the concentration of the other additives could be considerably reduced. The electrolyte containing polyaniline dispersion could also be efficiently used under production conditions. 相似文献
