对西双版纳的15种主要大型丛生竹的纤维形态和化学成分进行了分析,结果表明:15种竹材的纤维形态和化学成分的差异较大,纤维长度为1.49~5.25 mm,平均为2.72 mm;纤维长宽比为102~320,平均为179.2;纤维素含量为44.87%~52.60%,平均为49.09%;木质素含量为21.70%~28.13%,平均为24.36%;戊聚糖含量为13.76%~18.70%,平均为16.27%;灰分含量为0.80%~3.20%,平均为1.925%;S iO2含量为0.25%~1.39%,平均为0.683%。造纸性能综合评价结果表明:料慈竹、小叶龙竹、版纳甜龙竹和刀把竹均是优良的造纸原料,在热带、亚热带地区发展竹浆造纸时可以优先考虑;撑绿杂交竹、油簕竹、香糯竹、龙竹、黄竹和沙罗单竹的造纸性能也比国内目前常用的麻竹好。
The fiber morphology and chemical composition of 15 major bamboo species in Xishuangbanna were analyzed. The results showed that the fiber morphology and chemical composition of 15 bamboo species varied widely, the length of fiber was 1.49-5.25 mm, the average was 2.72 mm. The fiber The aspect ratio was 102-320 with an average of 179.2. The content of cellulose was 44.87% -52.60% with an average of 49.09%. The content of lignin was 21.70% -28.13% with an average of 24.36%. The pentosan content was 13.76% 18.70%, with an average of 16.27%; ash content of 0.80% ~ 3.20%, an average of 1.925%; S iO2 content of 0.25% ~ 1.39%, an average of 0.683%. The results of comprehensive evaluation of papermaking performance show that the materials of Ziziphus chinensensis, Betula albojum, Banana sweety bamboo and bamboo knife are all excellent raw materials for paper making. In the development of bamboo pulp in the tropics and subtropics, Bamboo, incense waxy bamboo, dragon bamboo, yellow bamboo and sand single bamboo papermaking performance is also better than the domestic commonly used bamboo.
