在此次中试研究中，确定了木聚糖含量低的纤维用量对纸张性能的影响。用碱抽提浆代替部分或全部漂白桦木硫酸盐浆，能够得到其对纸机湿部化学和最终纸张性能的影响。结果表明，用碱抽提浆代替部分漂白桦木硫酸盐浆可以保持甚至优化纸张性能。在纸机上网浆料中配入一定量的碱抽提浆，有利于一次留着和化学品的留着。然而，由于湿部电荷平衡的变化，因此对化学品用量的精心优化是必要的。本次研究的结果可用于预测不同木聚糖含量的纸浆，对纸机湿部化学和最终纸张性能的影响。

In this scale-up study, we examined the effects of using varying amounts of ifbers with reduced xylan content in paper. Bleached birch kraft pulp was partially or fully replaced by alkali-extracted pulp, and the effects of this replacement on the wet end chemistry of the paper machine and the resulting paper properties were determined. Our results show that paper properties can be maintained or improved when optimizing the partial replacement of bleached birch kraft pulp with alkali-extracted pulp. The incorporation of alkali-extracted pulp in paper machine stock had a positive effect on first pass retention and retention of chemicals. However, careful optimization of chemical dosages is required because of the altered charge balance in the wet end. The results of this study can be applied to predict the implications of varying pulp xylan content on the wet end chemistry of the paper machine and the resulting paper properties.
