对甜竹原料、甜竹浆的纤维形态进行了研究.结果表明:甜竹原料纤维平均长度为2.37mm、平均宽度17.91μm、长宽比值132.40;纤维平均壁厚为8.13μm、平均腔径为2.57μm、壁腔比值 6.33.研究了在蒸煮过程中纤维形态的变化.结果表明,在蒸煮过程中甜竹纤维长度不断变小,从2.37mm(原料)到1.79mm(全浆),减少24%;蒸煮过程中纤维长宽比值也不断缩小,从132.40(原料)到98.89(全浆).与青皮竹浆、桉木浆(阔叶木)、马尾松浆(针叶木)和麦草浆(草类)的纤维形态相比,甜竹浆纤维长度大于麦草浆纤维,小于马尾松浆纤维, 与青皮竹浆和桉木浆纤维长度基本相近,因此甜竹浆纤维属于长纤维范围,是一种优良的造纸原料.

The fiber morphology of sweet bamboo (Dendrocalamus latiflorus Munro.) materials and sweet bamboo pulp from Vietnam had been studied. The results show that:average fiber length of sweet bamboo materials is 2.37 mm, average width of fiber is 17.91μm, the average length/width ratio is 132.40; average wall thickness is 8.13μm, average cavity diameter is 2.57μm, the average wall/cavity is 6.33. The change of fiber morphology during cooking process is researched, the results show that, fiber length in the process of cooking decreased constantly, from 2.37mm(raw material) to 1.79mm(pulp), or reduced 24%, length/width ratio of fiber also decreased constantly, from 132.40(raw material)to 98.89(pulp). Compared with Bambusa textilis McClure pulp, Pinus massoniana Lamb. pulp, eucalyptus wood pulp and wheat straw pulp (grass type), the fiber length of sweet bamboo pulp fiber is greater than wheat straw pulp fiber and less than P.massoniana pulp, and similar to B.taxtilis pulp and eucalyptus wood pulp. Thus sweet bamboo fibers belongs to long fiber, which is a good paper-making raw material.
