3、iberstructureand crystalline structure were investigated and compared with those of cotton and flax and ramie fibers byoptical microscopy, scanning electron microscope and X-ray diffraction analysis. The investigation showed thatbamboo fiber is long cylindrical and uniform in size with distinct node
4、s, which is similar to flax and ramiefibers, however its length is far less than that of cotton, ramie and flax fibers. Bamboo fiber has a smallorientation angle for the exterior microfibers, which are parallel to fiber axis approximately. The structure ofconcentric lamina in cross section of bamboo
5、 fiber had been observed by SEM. Theresult of X-ray diffractionanalysis indicated that crystallinity and orientation of bamboo fibers were similar to those of ramie fibers, andmorethan thoseof cotton and flax fibers, in addition, crystallite size of bamboo fiber was biggest among thefour fibers. The
