In this paper, the application of peroxide: sodium percarbonate and hydrogen peroxide, in the chemical degumming process of ramie was discussed. Two kinds of effects of peroxide degumming process were analyzed. On the basis of that, the fiber properties of degummed ramie of oxidation degumming process and the traditional chemical degumming process were compared. The result showed that two kinds of peroxide can be effectively applied to the chemical degumming process of ramie. In comparison with the traditional chemical degumming process, there are many advantages in the oxidation degumming process, for example, short flow, saving in energy, less environmental pollution, high single fiber strength, high whiteness, less fiber strand and so on.
