【摘要】 对狼毒根的化学成分、纤维形态进行了分析,并与藏纸进行了对比。结果表明:狼毒根纤维苯醇抽出物高,为29.19%。木质素、纤维素及戊聚糖含量均低于一般木材。狼毒根纤维细长,1.5mm以上的占到52.62%,纤维平均宽度18.8μm,平均壁厚6.7μm。成纸后平均壁厚为3.7μm,平均宽度17.8μm,纤维的形态趋于一致。更多还原

【Abstract】 Chemical compositions and fiber morphology of Stellera chamaejasme L root and Tibetan paper were analyzed.The results show that: the benzene-ethanol extractives of Stellera chamaejasme L is as high as 29.19%.Lignin,cellulose and pentosan contents are lower than those of woods.Stellera chamaejasme L root fiber is long and thin,fibers from 1.5mm to 7.6mm is about 52.62% of the total.The average fiber width is 18.8μm,fiber wall thickness is 6.7μm.Fiber wall thickness and fiber width of Tibetan paper are 3.7μm and 17.8μm respectively,which gives an information of fiber morphology to be homogenized after pulping.更多还原
