| Abstract: |
| Scanning electron microscope （SEM） was utilized to investigate the microscopic characteristics of the bast fibers of Stellera chamaejasme and the fibers of five commercial Tibetan papers and the twist structures of Stellera chamaejasme bast fibers and cotton fibers were compared. The results indicated that a portion of bast fibers of Stellera chamaejasme presented natural twists resembling that of cotton fibers； bast fibers had a flat-ribbon structure， its surface exhibited irregular dents or prismatic vertical stripes while the surface of cotton fibers was densely covered with pleated filaments， indicating distinct ultrastructural differences between the bast fibers and cotton fibers. The fibers of 5 commercial available Tibetan papers differed in micro-morphology based on their sources. In addition， the papermaking raw materials used by the same manufacturer were different depending on the paper grades. The research results provided an ultramicro-morphological basis for identifying the fiber structure of Tibetan papers and had a particular reference value for choosing appropriate Tibetan papers. |
