Abstract

Abstract: As a bast fiber, cotton-straw bast fiber consists of cellulosic and non-cellulosic substances, such as hemicellulose, pectin, lignin, and wax, and these noncellulosic substances affect the application of cotton-straw base fiber. Alkali-H2O2 treatment does not only remove hemicellulose, lignin and pectin effectively, but bleach fiber as well. Through orthogonal experimental, the degumming for first boiling and second boiling of alkali-H2O2 was investigated. Experimental results showed that the optimum combination of parameters for first boiling was 8g/L NaOH, 9g/L H2O2, 1:100 bath ratio and 30min treatment time by using mathematical statistic analysis. Optimum technological parameters of second boiling for degumming of cotton-straw base fiber were alkaline content 12g/L, hydrogen peroxide content 17g/L, temperature 80 , and time 60min by using the fuzzy comprehensive evaluation
