Rate of hydrogen peroxide decreasing is very important for effective, economical and problem-free bleaching process. Optimal temperature, pH, concentrations of hydrogen peroxide and stabilizers are used in the bleaching bath to bleach the cotton fabric effectively. In the study, it is tried to optimize the bleaching recipes in terms of hydrophility and whiteness degree CR - 1. Ahn B.
