Oxygen bleaching, retreat, boiling, and bleaching bath process, generally, the use of hydrogen peroxide is in an alkaline, and H2o2 is activated with strong oxidizing under alkaline conditions. Therefore, in order to have good control of the process of decomposition of hydrogen peroxide in oxygen bleaching, bath desizing, scouring and bleaching, and inhibit the catalytic material to reduce the fiber damage which HO2 and HO cause, and get a good bleaching effect. In addition, we should control the pH of the bleaching, and also need to add hydrogen peroxide stabilizer to slow down hydrogen peroxide decomposition rate, which makes H2O2 decomposition effective.
