Influence of pretreatment of hydrogen peroxide on homochromaticity of half degummed silk/cotton mixed fabrics dyed with reactive dyes

The experiment studied the oxidation modification made by the pretreatment of hydrogen peroxide to the tryptophan side base indole structure and tyrosine side phenolic structure in the sericin protein of half degummed silk / cotton mixed fabrics,so as to realize the homochromatic dying of the fabric,three reactive dyes suitable for this purpose were screened out and the corresponding production process was determined. The research result has demonstrated that the dye-uptake rate of silk / cotton mixed fabrics during dyeing with reactive dyes will definitely drop down along with the increase of hydrogen peroxide and the prolongation of treatment duration.
