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.
