Abstract
In order to overcome the problems of cotton stalk bast fibers such as hard handle, poor separation, the method of high temperature degumming was studied. Cotton stalk bast fibers were first pretreated with H2O2 and then treated by the method of high temperature degumming. The effect of such factors as concentration of alkaline, temperature, temperature holding time and liquor ratio on content of lignin and residual gum was researched with the orthogonal experiment, and the binary quadratic orthogonal regression experiment was made to optimize the degumming process. The optimal conditions were concentration of sodium hydroxide 11.26%, treating temperature 132.4 ℃ , temperature holding time 50 min and liquor ratio 1 : 20. The SEM results showed that the fiber separation were improved by degumming at high temperature.关键词
