A Fe-complexed dye containing crosslinkable polyamine groups was synthesized through diazotization and coupling reaction, chlorination,amination and metallization.The structure of the Fe-complexed crosslinking dye was characterized by FT-IR and Atomic Absorption Spectroscopic techniques.The dyeing and light fastness properties of the Fe-complex on silk and wool were tested,and the results showed that the novel Fe-complex exhibited both high fixation and good light fastness.
