稀土在棉纱染色中的作用

An Effect of the Rare-earth Elements on the Dyeing Process of Cotton Yarn

制备了可以在碱性条件下使用的稀土与二乙三胺五乙酸和柠檬酸的络合物,并研究它们在棉纱染色中的作用。本文研究表明稀土络合物对提高活性染料染色棉纱的鲜艳度和牢度有较明显的作用。

Complexes of rare earths with diethylene-triamine-penta-ethanoic acid and citric acid, both of which can be applied under basic condition, were prepared. The functions of these two complexes in the cotton yarn dyeing were investigated. This paper emphasized the fact that the rare earth complexes did had the eminent effects of enhancing the brilliancy and colour fastness of the cotton yarn dyed with reactive dye.
