Research on the Bleaching Process of the Non-Silicon Oxygen Bleaching Stabilizer

Abstract:

In this study, a type of non-silicon oxygen bleaching stabilizer was used to cotton fabric in the hydrogen peroxide bleaching process. This type of novel non-silicon oxygen bleaching stabilizer was prepared mainly with ethylene diamine tetraacetic acid (EDTA) and magnesium chloride. The results showed that adding the non-silicon oxygen bleaching stabilizer into the bleaching solution obviously decreased the hydrogen peroxide decomposition rate and improved the fabric whiteness. Optimal conditions was found as follow: non-silicon oxygen bleaching stabilizer 4.5 g/l; bleaching temperature 75-85 °C; pH of bleaching liquid 11; bleaching time 40-45 min. In summary, the results showed that the self-made non-silicon oxygen bleaching stabilizer could make the cotton fabrics obtained great whiteness, capillary ability and breaking strength.
