This study aims to understand the effect of micro- and nanofibrillated cellulose (MNFC) on the tensile index, softness, and water absorbency of tissue paper. MNFC was produced from four different fiber sources. The results show that MNFC acts as an effective strength enhancer at the expense of a reduced water absorbency and softness. The impact of the fiber source on MNFC manufacturing cost and the trade-off with performance was also investigated. MNFCs produced from southern bleached hardwood kraft, northern bleached softwood kraft, and deinked pulp exhibited similar performance trends with the MNFC from the deinked pulp having a significantly lower cost. This suggests that MNFCs with similar degrees of fibrillation may be used interchangeably regardless of the fiber source, revealing the possibility to minimize MNFC manufacturing costs based on fiber selection. MNFC produced from bleached Eucalyptus kraft showed the lowest degree of fibrillation and the lowest strength improvements among the MNFCs evaluated.

这项研究旨在了解微纤维和纳米原纤化纤维素（MNFC）对薄页纸的拉伸指数，柔软度和吸水性的影响。MNFC由四种不同的纤维来源生产。结果表明，MNFC是有效的强度增强剂，但吸水性和柔软性降低。还研究了纤维源对MNFC制造成本的影响以及性能之间的权衡。由南方漂白的硬木牛皮纸，北方漂白的软木牛皮纸和脱墨纸浆生产的MNFC表现出相似的性能趋势，而脱墨纸浆的MNFC具有明显较低的成本。这表明原纤维化程度相似的MNFC可以互换使用，而与纤维来源无关，揭示了基于光纤选择使MNFC制造成本最小化的可能性。在所评估的MNFC中，用漂白的桉木牛皮纸生产的MNFC显示出最低的原纤化程度和最低的强度改进。
