TS123; To overcome the shortcomings of traditional degumming process,an efficient and environmentally friendly ethylene glycol(EG)degumming process was adopted to degum hemp fibers.The surface morphology,chemical composition,chemical structures,and mechanical properties of the fiber samples were analyzed to explore the mechanism of the degumming process.It was found that the EG degumming process could be divided into the main degumming stage(heating)and the supplementary degumming stage(insulation).The removal rates of hemicellulose and lignin in the main degumming stage were 70.56％and 60.17％,respectively.In the supplementary degumming stage,9.95％hemicellulose and 25.39％lignin were removed.It is confirmed that EG can separate hemp fibers effectively with less damage,which holds great potential for the biomass fiber separation technology.
