提高活性染料吸尽率和固色率的方法

Methods for Improving Reactive Dyes＇ Absorbability And Degree of Fixation

本文概述了提高活性染料吸尽率和固色率的几种方法。而重点介绍了将活性染料中的活性基团β-乙烯砜基硫酸酯与磷酸盐（如乙酰二磷酸等）的衍生物以及糖类（如葡萄糖、蔗糖等）进行反应，可制得具有高吸尽率（〉95％）、高固色率（≥95％）的活性染料。

Several methods for improving reactive dyes＇ absorbability and degree of fixation have been generaliged in the article. The author empbatically presented that taking the reactive radical, β-ethyl sulfuryl sulphate, to react with phosphates derivatives （ such as acetyl di-phosphate） as well as saccharides （ such as glucose, sugan etc, ） reactive dyes of high absorbability （〉95%） and high degree of fixation （≥95%） could be prepared.
