Non-wood is one of the most important raw materials for pulp and paper production in several countries due to its abundance and cost-effectiveness. However, the pulping and papermaking characteristics of canola straw have rarely been investigated. The objective of this work was to determine the potential application of canola straw in the chemimechanical pulping (CMP) process. At first, the chemical composition and characteristics of canola straw were assessed and compared with those of other non-woods. Then, the CMP pulping of canola straw was conducted using different dosages of sodium sulfite and sodium hydroxide. The results showed that, by applying a mild chemical pretreatment, i.e., 4-12% (wt.) NaOH and 8-12% (wt.) Na(2)SO(3), in the CMP pulping of canola straw, the pulp brightness reached almost 40%ISO, and the strength properties were comparable to those of bagasse CMP and of wheat straw CMP. The impact of post-refining on the properties of canola straw CMP was also discussed in this work.
非木材是几个国家纸浆和造纸生产的最重要的原材料之一，因为它的丰富和成本效益。然而，油菜秸秆的制浆和造纸特性很少被研究过。本工作的目的是确定油菜秸秆在化学机械浆（CMP）过程中的潜在应用。首先，评估了油菜秸秆的化学成分和特性，并与其他非木材进行了比较。然后，用不同剂量的亚硫酸钠和氢氧化钠进行油菜秸秆的 CMP 制浆。结果表明，通过应用温和的化学预处理，即 4-12%（wt.）NaOH 和 8-12%（wt.）Na2SO3，在油菜秸秆的 CMP 制浆中，纸浆的白度达到近 40%ISO，强度性能可与甘蔗渣 CMP 和麦草 CMP 相媲美。本文还讨论了后精炼对油菜秸秆 CMP 性能的影响。
