The results of the application and systemic tests showed that the reduction of the dyestuff amount, the increase in the dyeing fastness and the improvement of the dyestuff absorption could be found, when it was used in the leather dyeing.

The effects of the reasonable use of a series dyeing assistants on leather dyeing were studied.

In this paper, action mechanism on metal ion( Zr 4+ ) and black dyestuffs in leather dyeing was studied.
