Mechanism of rare earth in real silk dyeing

HUANG Xiao-hua, WANG Xin-ming(Textile and Garment Engneering Department, AnHui Institute of Mechanical and Electrical Engineering, Wuhu 241000,China)  
The paper investigated the mechanism of YbCl3 on real silk fiber by determining the amounts of Yb3+ in the fabric with different pH value , the visible absorption spectrum curve of the solution of Yb3+ and percentage of dye exhaustion and color fastness. The study showed that YbCl3 increased the percentage of dye exhaustion at pH value above the equal-charge point of real silk fiber and heightened color fastness . Ionic action is dominating and complexing action is minor.
