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.
本研究旨在探讨微纤化纤维素和纳米纤化纤维素对纸巾的拉伸指数、柔软度和吸水性的影响。MNFC 由四种不同的纤维来源制成。结果表明，MNFC 可作为一种有效的增强剂，但其吸水性和柔软度降低。还研究了纤维来源对 MNFC 制造成本的影响以及与性能的权衡。来自南方漂白硬木牛皮浆、北方漂白软木牛皮浆和脱墨浆的 MNFC 表现出相似的性能趋势，其中脱墨浆 MNFC 的成本显著降低。这表明，具有相似纤维化程度的 MNFC 可以互换使用，而不考虑纤维来源，这表明可以根据纤维选择来最小化 MNFC 的制造成本。在评估的 MNFC 中，来自漂白桉木牛皮浆的 MNFC 显示出最低的纤维化程度和最低的强度提高。
