  Abstract

The metal complex dyes that are mainly used for good color fastness in dyeing amide fibers with highly concentrated colors usually contain toxic chromium. The remaining dye in th dyebath containing Cr^(6+) causes not only environmental problems but also serious damages to human hεaltho In this study, we applied reactive dyestuff for dyeing wool and nylon in order to substitute heavy metal dyestuff. The dyeing properties ofreactive dyestuff in fibers as well as their absorption rates and fastness according to color concentration were investigated. By analyzing the quantity of heavy metals and toxic amine of reactive dyestuff, we investigated their harmfulness trends quantitatively. By comparing the reactive dyes with traditional metal complex dyes, we tried to find out the possibility ofthe reactive dye being a clean dyes in the future.
