摘要
为研究竹浆的纤维构成及化学组成,以漂白硫酸盐竹浆为原料,用保尔筛分仪进行筛分,然后对各组分的纤维形态进行观察,并对其化学组成进行分析.结果表明:竹浆中长组分纤维的纤维素含量高,半纤维素、木素及灰分的含量低;而短组分纤维的纤维素含量低,半纤维素、木素及灰分含量高.竹浆细胞及纤维的组成相对繁杂,通过筛分可以把不同形态的纤维分开,以实现竹浆纤维的分级利用和长纤维的高质化利用.
The bleached kraft bamboo pulp was classified using Bauer-McNett,then the fiber morphology of the fractionations were observed and the chemical compositions were determined.The experiment shows that long fractionation contains more cellulose,less hemicellulose,lignin and ash than short fractionation does.The fiber composition of bamboo pulp is complex,the long fiber and short fiber could be classified and applied separately.So it can achieve by the way of classification that hierarchical utilization of bamboo pulp and high quality utilization of long bamboo fiber.
