Abstract

Metal acid dyes are usually used to dye wool fabric to achieve high concentrated color and strong color fastness. However, metal acid dyes contain lots of heavy metal. That causes not only environmental pollution but also diseases to human. In this study, wool reactive dyes instead of metal acid dyes for wool, which are environmental friendly, are compared and analyzed in the evaluation system of their harmfulness, containing heavy metals and examined exhaustion rates and dyeing characteristics.
