硫酸铜三氯化钕助染羊毛酸性染料染色比较研究

Reseach of Colouring of Fleece in acid Dyes with Copper Sulphate and Neodymium Chloride

研究比较了CuSO_4、NdCl_3助染时酸性大红GR、酸性大红3R、酸性橙Ⅱ对羊毛的染色反应。对酸性橙Ⅱ、CuSO_4、NdCl_4助染提高了色牢度,对酸性大红GR、酸性大红3R,色牢度则没有提高,CuSO_4染样时样品鲜艳度降低,NdCl_3则使鲜艳度增加。

The colouring of fleece in acid red GR, acid red 3R and acid orange Ⅱ with copper sulphate and neodymium chloride is studied in this article. The colour fastness in both improved in acid orange Ⅱ in presence of CuSO4 and NdCl3, this effect does not appear in acid red GR and acid red 3R. The colour brightness of samples is increased in the three acid dyes with NdCls and decreased with CuSO4.
