淡竹化学成分与纤维形态的研究

Research on chemical composition and fiber morphology of henon bamboo(Phyllostachys glauca)

以4种竹龄的淡竹为研究对象,对其化学成分和纤维形态进行了测试和分析。结果表明,淡竹灰分含量为3.69%,苯醇抽提物含量为2.98%,酸不溶木素含量为19.30%,综纤维素含量为70.80%,纤维素含量为39.20%,聚戊糖含量为23.06%;不同竹龄、部位淡竹纤维平均长度为1.24 mm,平均宽度为15.31μm,平均长宽比为81.29。要用来做纸浆生产原料,宜首选3年生淡竹竹材。

The chemical composition and fiber morphology of 4 kinds of henon bamboo were studied in this paper. The results showed that henon bamboo contains 3.69% of ash, 2.98% of benzene-alcohol extractive, 19.30% of lignin, 70.80% of holocellulose, 39.20% of cellulose, and 23.06% of pentosane; the average fiber length and fiber width were 1.24 mm and 15.31 μm, respectively; the length/width ratio of 81.29. The 3-year-old henon bamboo is suitable material for making paper.
