摘要:为掌握竹原纤维制备过程各阶段试样的形态结构和理化性能,更好地开发利用竹原纤维,采用扫描电镜法、红外光谱分析法、X 射线衍射法、热重分析法和X射线光电子能谱(XPS)对竹原纤维加工成形各阶段样品进行了纵向测试分析。指出:竹单纤维呈圆形截面,中腔有微小的溶胀趋势,纵向有胶质黏连;竹原纤维制备过程并未改变天然竹纤维的结晶结构与属性,但结晶度呈递增趋势;竹原纤维制备过程各试样主要官能团结构无明显变化;试剂的使用改变了纤维表面的化学变化,C-C 相对其他的碳含量降为73.33%,木质素降解、部分结构变化。

Abstract:In order to master the morphological structure and physical and chemical properties of the samples of the bamboo raw fiber at each stage of preparation process,and develop and utilize bamboo raw fiber better.Scanning electron microscopy,infrared spectroscopy,X-ray diffraction,thermogravimetric analysis and XPS are used to conduct longitudinal testing and analysis on samples of bamboo raw fiber processing and forming at each stage.It is pointed out that the single fiber of bamboo has a circular cross section,with a slight swelling tendency in the middle cavity and a gelatinous adhesion in the longitudinal direction.The crystallization structure and properties of natural bamboo fiber are not changed during the preparation process,but the crystallinity increased.The main functional group structure of each sample do not change significantly at each stage of preparation process of the bamboo raw fiber.The chemical changes of the fiber surface are changed by using reagent,the carbon content of C-C was reduced to 73.33%,lignin is degraded,and part of the structure is changed.  
Key Words:bamboo raw fiber;morphological structure;scanning electron microscope;infrared spectroscopy analysis;X-ray diffraction;thermogravimetric analysis;XPS
