摘要
为实现毛竹更有效的化学加工和利用,文章以3~4年生毛竹为对象,研究了脱木素处理对毛竹材径向不同部位的纤维形态和化学成分的影响。结果表明:脱木素处理对竹材径向各部位纤维宽度和壁厚影响较为显著,对纤维长度的影响则不显著;随着处理时间增加,纤维长宽比呈减小趋势、纤维壁腔比呈增大趋势;竹材径向各部位纤维素相对结晶度随着脱木素处理时间的延长呈现增加趋势;与近竹青部位和竹中部位相比,脱木素处理对近竹黄部位的纤维形态和化学成分的影响更为显著。
In order to achieve more effective chemical processing and efficient utilization of moso bamboo,this study takes 3-4-year-old Phyllostachys edulis to explore the effect of delignification on fiber morphology and chemical component in different parts along the radial direction of moso bamboo.The results show that delignification has a significant effect on fiber width and wall thickness,but little effect on fiber length.With the increase of processing time,the fiber length-width ratio decreases and the fiber wall-cavity ratio increases.The relative crystallinity of cellulose increases with the extension of delignification time.Compared with the green part and the middle part of bamboo culm,delignification has more significant effect on the fiber morphology and chemical components of the yellow part.
