Extraction and Characterization of Novel Natural Cellulosic Fibers from Pigeon Pea Plant

ABSTRACT

This study is mainly focused on the extraction and characterization of the lingo-cellulosic fibers from the Pigeon Pea plant. The chemical components of the fibers such as cellulose content (55.03%), lignin (18.32%), wax content (2.38%), moisture content (8.13%), and density (1.7389 g cc⁻¹) were identified. Functional groups present in the fibers were obtained by infrared spectroscopy. By using X-ray diffraction analysis, Crystallinity Index is found to be 68% and thermogravimetric analysis showed that thermal degradation of the fiber begins at 225°C.The results suggest that the Pigeon pea fibers can be used as reinforcement in polymer-matrix composites.

摘要

本研究主要是从木豆植株中提取和鉴定纤维素纤维。测定了纤维中纤维素含量（55.03%）、木质素（18.32%）、蜡含量（2.38%）、水分含量（8.13%）和密度（1.7389g cc_1）等化学成分。通过红外光谱获得纤维中存在的官能团。通过X-射线衍射分析,发现该纤维的结晶指数为68%,热重分析表明,该纤维的热降解起始于225°C,表明该纤维可以作为聚合物基复合材料的增强材料。
