Abstract: This paper tests a method which is the fabric made of silk and cotton with semi degumming reactive dyes dyed the same color that can’t achieved by the conventional dye acidity Control Act. This method is in silk scouring process, through the hydrogen peroxide solution to silk dyeing group oxidation modification effect, to achieve the purpose of the fabric made of silk and cotton with half degumming and homochromatism dyeing.At the same time, it also selects three reactive dyes suitable for the fabric made of silk and cotton with half degumming and homochromatism dyed staining red, yellow,and blue.

Key words: silk , ∕cotton homochromy, sericin dyeing, half degumming, hydrogen peroxide, reactive dye
