摘要:本研究以硫酸盐竹浆为研究对象，探讨了杂细胞对打浆前后竹浆的纤维形态、打浆度、保水值及成纸性能的影响。结果表明，竹浆中杂细胞的含量会对竹浆打浆性能产生显著的影响。在相同打浆转数下，随着杂细胞含量的增加，竹浆打浆度、保水值和纤维扭结明显提高，竹浆纤维的卷曲度和分丝帚化程度下降。在相近打浆度下，随着杂细胞含量的增加，竹浆成纸的耐破指数、撕裂指数和耐折度呈下降趋势，抗张指数在杂细胞含量为3%时最佳，达78.3 N·m/g。

Abstract:In this study， kraft bamboo pulp was used to explore the effects of non-fibrous cells on fiber morphology， beating degree， water retention value and paper properties of kraft bamboo pulp before and after beating. The results showed that the content of non-fibrous cells in bamboo pulp had a significant impact on the beating performance. Under the same number of beating revolutions， the beating degree， water retention value and fiber kink of bamboo pulp were improved obviously， while the degree of fiber curl and fibrillation were decreased with the increase of non-fibrous cells content. Under the similar beating degree， with the increase of non-fibrous cells content， the burst index， tear index and folding endurance of bamboo pulp paper showed a downward trend， and the tensile index was the best when the non-fibrous cells content was 3%， reaching 78.3 N·m/g.
