ABSTRACT

This current study aims to evaluate the suitability of a new cellulosic fiber by characterization methods. Raw fibers are extracted from the rinds of Thespesia Populnea plant by the water-retting process. The extracted raw fibers are treated with 1% (w/v) of NaOH solution with a soaking time of 90 minutes. The characterization outcomes report that alkali treatment increases the crystalline index and cellulose content from 41% to 65% and 52.5 wt% to 58.9 wt%, respectively. The FT-IR spectra analysis confirms diminishing of non-cellulosic substances in alkali-treated fiber. The alkali treatment alters the fiber surface and fiber diameter, which is evidenced in morphological analysis.

摘要

本研究旨在通过表征方法评估新型纤维素纤维的适用性。原料纤维是通过水沤工艺从白杨属植物的外皮中提取的。提取的粗纤维用 1% (w/v) 的 NaOH 溶液处理，浸泡时间为 90 分钟。表征结果表明，碱处理将结晶指数和纤维素含量分别从 41% 提高到 65% 和从 52.5 wt% 提高到 58.9 wt%。FT-IR 光谱分析证实了碱处理纤维中非纤维素物质的减少。碱处理改变了纤维表面和纤维直径，这在形态分析中得到了证实。
