| Abstract:In this study， six bamboo species of the genus Cephalostachyum Munro in China were taken as research objects， and their fiber morphology and structure were investigated using techniques such as field emission scanning electron microscopy （FESEM） and two-dimensional wide-angle X-ray powder diffractometer （2D WAXD）. The results showed that the anatomical structures of all six bamboo species lacked fiber bundle， and the vascular bundle types were all typically slender waist type. The morphology of fibers were similar in overall shape and they were relatively rigid， among which the fiber of Cephalostachyum scandens Bor had the longest length （2.25 mm）， with a high proportion of fibers of length >3.20 mm. The microfibril angles of fiber from the six bamboo species ranged from 8.46° to 14.79°， with Cephalostachyum scandens Bor fiber exhibiting the largest microfibril angle （14.79°）. There were no significant differences in the zero-span tensile indices of fibers among the six species， and Cephalostachyum pallidum Munro had the highest values （0.212 kN·m/g in dry method and 0.193 kN·m/g in wet method）， followed by Cephalostachyum scandens Bor （0.189 kN·m/g in dry method and 0.173 kN·m/g in wet method）. |
