| 摘 要： | The morphology and supermolecular structures of the scoured/bleached ramie and scoured/bleached/liquid ammonia treated ramie were studied by means of scanning electron microscope, X-ray diffractometer, reverse gel permeation chromatography, etc. The results indic.ate that liquid ammonia treatment of the scoured/bleached ramie leads to a smoother surface, a lower crystalliuity, partial crystal transformation from cellulose Ⅰ to cellulose Ⅲ a decrease in the volume and cumulative surface area of the larger micropores and an increase in those of the smaller ones in the fiber.
