Pulp and Paper Making Characteristics of Fibers from Plantation-grown Oxythenantera Abyssinica and Beema Bamboo (A Tissue Cultured Clone from Bambusa Balcooa)

ABSTRACT

The alarming global deforestation rate has great impacts on the output of the Pulp and paper Industry since wood is the principal papermaking fiber material. Although, generally, bamboo is an alternative cellulolytic fiber source, the species and culm age have great effects on its papermaking potential. Based on the methods by the International Association of Wood Anatomists (IAWA), this work assessed the characteristics of fibers from the axial culm sections of six-month plantation-grown Oxythenantera abyssinica and Beema bamboo (which was cloned from Bambusa balcoaa) for paper production. The lengths of the fibers ranged from 1.89 to 2.39 mm while the diameters were 0.025–0.031 mm. The fiber lumen diameter and wall thickness were 0.014–0.018 mm and 0.004–0.006 mm, respectively. Fibers from the species had their runkle ratios below 1, slenderness ratios above 70 and flexibility ratios above 50. These characteristics compare well with the recommendations for fibers often used for the production of packaging, writing and printing papers. Establishment of plantations of Beema bamboo and O. abyssinica is encouraged as they will serve as good raw material base for the paper industry within six months of planting. Additionally, their planting will contribute to meeting Sustainable Development Goals 1 and 13.

摘要

由于木材是主要的造纸纤维材料, 全球森林砍伐率惊人, 对制浆造纸工业的产量产生了巨大影响. 尽管竹子通常是一种可替代的纤维素分解纤维来源, 但竹种和竹龄对其造纸潜力有很大影响. 采用国际木材解剖学家协会 (IAWA) 的方法, 对6个月人工林的深松楠木 (Oxythenantera abysinica) 和克隆自balcoaa竹 (Beema Bambusa balcoaa) 的竹材进行了纤维特性的研究. 纤维长度为1.89～2.39mm, 直径为0.025～0.031mm. 纤维腔直径为0.014～0.018mm, 壁厚为0.004～0.006mm。该种纤维的runkle比小于1, 长细比大于70, 柔度比大于50. 这些特性与通常用于生产包装, 书写和印刷纸的纤维的建议相比较. 鼓励建立山毛竹和金钱草种植园, 因为它们将在种植后6个月内成为造纸工业的良好原料基地. 此外, 它们的种植将有助于实现可持续发展目标1和13.
