Abstract

"In this study, cellulose fiber was extracted from bamboo shoot shell with a deep eutectic solvent (DES). The deep eutectic solvent used was prepared by the fusion of choline chloride (ChCl), oxalic acid (OA) and ethylene glycol (EG) at 80 °C. Based on the degumming rate, the influence of temperature and time on the DES degumming system was determined. Based on the scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and thermogravimetric analysis (TG) results, it was confirmed that the DES system can remove colloids from bamboo shoot shell, increasing the thermal stability and heat resistance of bamboo shoot shell fiber, and improving its crystallinity. It was proved that the DES system can effectively remove lignin and hemicelluloses, and retain cellulose in bamboo shoot shell."
