Study on the Physical and Chemical and Mechanical Pulping Characteristic of Cotton Stalk Fiber

Abstract:

Straw resource was tremendous, however it was utilized poorly. So the research of physical, chemical and mechanical pulping properties of cotton stalk fiber laid the foundation for utilization of cotton stalk. Morphology of cotton stalk fiber was determined by Feica microscope, the length, width and length to wide ratio were analyzed by SPSS 17.0. Chemical composition changes of cotton stalk fiber after mechanical process were analyzed by applying Block test method with Design-expert 6.0.10.The result present that composition of fiber had significant difference. Hemicellulose decreased by 1.68 %, cellulose decreased by8.85 %, lignin increased by 5.87 %. Beating degree was positively correlated with the pulping time, beating time and wet weight were a negative correlation. Strength of cotton stalk fiber was positively with the gramme, and strength was 8.5 N when gramme was 60 g/m2.
