Accurate testing and mastering the reaction law of hydrogen peroxide on the fabric surface can effec- tively help study and develop the cotton knitted fabric bleaching and scouring technology. In this paper, a method for testing the decomposition rate of hydrogen peroxide on cloth surfaces is introduced, which is used to study the technology of cold pad-batch bleaching and scouring, cold pad-batch-short steaming bleaching and scouring, and continuous pad-steaming bleaching and scouring. Through the detection of different processing methods in decompo- sition of hydrogen peroxide on the cloth surface, testing cloth hydrogen peroxide decomposition rate, and testing whiteness and capillary affinity, it developed a reasonable and feasible process conditions, and conducted a pro- duction practice. The results show that the developed process conditions have better whiteness and capillary effect, and improve the effective utilization of hydrogen peroxide.
