With increasing global demand for paper, concerns about deforestation caused by conventional wood pulp production have highlighted the urgent need for sustainable alternatives. This work explored Super-Arundo donax as a promising substitutable non-wood raw material applied for pulping and papermaking. This research aimed to optimize the process conditions of two alkaline semi-chemical pulping (NaOH and NaOH: Na₂CO₃) from Super-Arundo donax by investigating the effects of different alkali dosages, cooking temperatures and times on the pulp and paper properties. The results showed that the optimum process conditions for NaOH semi-chemical pulping and NaOH: Na₂CO₃ semi-chemical pulping were NaOH dosage of 9 % N₂O and NaOH: Na₂CO₃ (4:1) of 12 % N₂O, cooking temperature of 130 ℃, cooking time of 90 min, solid-liquid ratio of 1:6, respectively. Under these parameters, the yield of NaOH semi-chemical pulp was 65.2 %, while the yield of NaOH: Na₂CO₃ semi-chemical pulp reached 65.68 %. Moreover, the tensile index, tear index and ring crush index of two papers made from NaOH and NaOH: Na₂CO₃ semi-chemical pulps under optimal conditions were 33.5 N·m/g, 6.33 mN·m²/g, 11.9 N·m/g and 30.5 N·m/g, 6.08 mN·m²/g, 11.6 N·m/g, respectively. The excellent physical strength properties were relevant to the dense fibrous network displayed on the surface morphology of the formed paper. The findings demonstrated that Super-Arundo donax semi-chemical pulp fiber presented a viable alternative for paper production to traditional wood pulp fiber, contributing to sustainable advancements in the pulp and paper industry.

Super-Arundo donax 作为纸浆和造纸工业的潜在非木材原料：不同蒸煮条件对碱性半化学纸浆和纸张特性的影响

随着全球对纸张的需求不断增加，对传统木浆生产造成的森林砍伐的担忧凸显了对可持续替代品的迫切需求。这项工作探索了 Super-Arundo donax 作为一种有前途的可替代非木材原料，用于制浆和造纸。本研究旨在通过研究不同碱用量、蒸煮温度和时间对纸浆和纸张性能的影响，优化 Super-Arundo donax 的两种碱性半化学制浆（NaOH 和 NaOH：Na₂CO₃）的工艺条件。结果表明，NaOH 半化学制浆和 NaOH：Na₂CO₃ 半化学制浆的最佳工艺条件分别为 NaOH 用量 9 % N₂O 和 NaOH：Na₂CO₃（4：1）12 % N₂O，蒸煮温度 130 °C，蒸煮时间 90 min，固液比 1：6。在这些参数下，NaOH 半化学纸浆的产量为 65.2 %，而 NaOH：Na₂CO₃ 半化学纸浆的产量达到 65.68 %。此外，在最佳条件下，NaOH 和 NaOH：Na₂CO₃ 半化学浆两种纸的拉伸指数、撕裂指数和环压指数分别为 33.5 N·m/g、6.33 mN·m²/g、11.9 N·m/g 和 30.5 N·m/g、6.08 mN·m²/g、11.6 N·m/g。优异的物理强度性能与成型纸表面形貌上显示的致密纤维网络有关。研究结果表明，Super-Arundo donax 半化学纸浆纤维是传统木浆纤维的可行造纸替代品，有助于纸浆和造纸行业的可持续发展。
