Abstract: The chemical composition and fiber morphology of Dendrocalamus brandisii was studied in this paper. The results show that D.brandisii contains 1.12% of ash, 27.08% of lignin, 72.96% of holocellulose, 15.51% of pentosane, 7.05% of cold-water extractive, 9.35% of hot-water extractive, 21.60% of 1% NaOH extractive, 0.35% of diethyl ether extractive, 3.46% of benzene-alcohol extractive;And the fiber length is 2.65 mm, fiber width is 15.26 μm, length/width ratio is 174, the fiber lumen diameter is 14.88 μm, fiber wall thickness is 2.80 μm, thickness/diameter ratio is 0.38, respectively. On the basis of chemical composition and fiber morphology, D. brandisii is one of the good materials for pulping.

Key words: Dendrocalamus brandisii, chemical composition, fiber morphology, paper-making industry
