摘　　要：以未漂马尾松硫酸盐浆生产纸袋纸,研究了纸袋纸高浓打浆(HCR)和低浓打浆(LCR)工艺,并对其纸浆和手抄片的性质进行了对比分析。研究结果表明,马尾松硫酸盐浆制纸袋纸其打浆工艺以高浓打浆为宜;其中,HCR更有利于保持纤维长度,而且撕裂指数、伸长率也明显高于LCR,虽然抗张指数、耐破指数低于LCR,但在改善纸袋纸抗张能量吸收(TEA)和透气度两个重要指标方面HCR明显优于LCR。High consistency refining(HCR) and low consistency refining(LCR) of unbleached Masson's pine kraft pulps for sack paper were studied in this article.The properties of their refined pulp and handsheet were analyzed comparatively.The results showed a high consistency refining was more suitable for sack paper with unbleached Masson's pine kraft pulp than a low consistency refining.High consistency refining is of advantage to retain the fiber length.The tear index and stretch of the handsheet of high consistency refining were higher than that of low consistency refining.The tensile energy absorption(TEA) index and air permeability of the handsheet of high consistency refining which were crucial properties of sack papers were better,though higher tensile index and higher burst index could be obtained with low consistency refining.
