Study of Alkali Treatment and Its Influence on Characteristics of Borassus Palm Fiber

ABSTRACT

Palmyra fibers are found to be the renewable and sustainable fiber in textile applications. These fibers possess good tensile strength and found to be used as a natural reinforcement material for composites. The main objective of this work is to extract and treat the fibers with varying concentrations of NaOH (2%,3%,4%& 5%) to evaluate the mechanical properties, surface morphology, and fiber orientation. The observations in SEM images denote the removal of impurities like hemi cellulose and lignin after the alkali treatment. 4% NaOH-treated fibers results in higher tensile strength (63.43 MPa) and a further increase in alkali concentration to 5% results in a reduction of the tensile strength (62.65 MPa). For all the treated fibers, elongation at break was found to be higher than the untreated one. The orientation in the fiber structure improves after the alkali treatment up to 4% and a further increase in alkali concentration leads to a decrease in the orientation which was observed through X-ray diffraction studies.

摘要

棕榈纤维被认为是纺织应用中可再生和可持续的纤维. 这些纤维具有良好的拉伸强度, 被发现用作复合材料的天然增强材料. 这项工作的主要目标是用不同浓度的NaOH(2%、3%、4%和5%)提取和处理纤维, 以评估机械性能、表面形态和纤维取向. SEM图像中的观察结果表明, 碱处理后, 半纤维素和木质素等杂质被去除. 4%NaOH处理的纤维具有更高的抗拉强度(63.43 MPa), 碱浓度进一步增加至5%会导致抗拉强度降低(62.65 MPa). 所有处理过的纤维的断裂伸长率都高于未处理过的纤维. 碱处理高达4%后, 纤维结构中的取向得到改善, 碱浓度的进一步增加导致通过X射线衍射研究观察到的取向降低.
