Study on Chemical Compositions and Fiber Morphologies of Bambusa Sinospinosa,Bambusa Blumeana and Dendrocalamus Yunnanicus Stem
摘要
Abstract
The chemical compositions and fibre morphologies of Bambusa sinospinosa, Bambusa blumeana and Dendrocalamus yunnanicus which are large sympodial bamboos were studied and compared with Bambusa textilis which is good fiber raw material for paper industry. The result showed that the holocellulose contents of three bamboos are 73.43% ,71.71% and 67.37% , and the contents of acid insoluble lignin are 23.13% , 21. 39% and 23. 72% respectively, which are all roughly equal to those of B. Textilis. Concerning the extractives, the benzene-alcohol extractives are lower, and 1% NaOH and water (100℃ ) extractives are slightly higher. In terms of fibre morphologies, the fiber length of three sympodial bamboos are 2.37 mm, 2.27 mm and 2.49 mm respectively, which all belong to long-fibre plant materials, and are also longer than that of B. Textilis. The ratio of fiber length to width of the three bamboos are 144, 124 and 128 respectively, which are equal or a little lower than that of B. Textilis; for the ratio of wall thickness of fiber cell to the lumen diameter, the three bamboos are all lower. The three sympodial bamboos are suitable for use as pulping raw material.关键词
