DA系列阳离子染色助剂的合成研究——多元胺的筛选与环氧丙烷结构单元的引入

Study on the synthesis of DA series of cationic dyeing assistants --selection of polyamine and induction of polyene epoxide structural unit

首先淘汰了会对 DA系列阳离子染色助剂成品带来异味的多元胺 ,然后通过探讨 DA染色助剂与染料的作用 ,对多元胺作了进一步的筛选 ;在此基础上 ,又考查了环氧丙烷结构单元的引入对染色助剂应用性能的影响。

The polyamine that can bring peculiar smell to the product of DA series cationic dyeing assistants were eliminated .Then more selection was made through the discussion of interaction between DA dyeing assistants and dyestuff. On the basis of which , the influence of the induction of propylene epoxide structural unit to the application properties of DA dyeing assistants was reviewed.
