Extraction and Characterization of Natural Fiber from Stem of Cardiospermum Halicababum

ABSTRACT

The current study deals with the investigation on the properties of lignocellulose fiber from the stem of Cardiospermum Halicababum. The Cardiospermum Halicababum fibers (CHF) were extracted from its stem by manual retting process. The retted fibers were analyzed for various physical, chemical, crystalline, thermal stability, tensile and morphological properties as per standard procedure. From the chemical investigation, it was found that the CHF has cellulose (59.82%), hemicellulose (16.75%), lignin (9.3%) and wax (1.3%). The CHF possessed a crystallinity index of 32.21%, with thermal stability up to 336°C. The average ultimate tensile strength of CHF was 20.7 ± 1.0 MPa. Morphological characteristics showed lesser lacuna space in between the cell walls thereby preventing the reduction in strength properties.

摘要

本文研究了大比目鱼心精茎木质纤维素纤维的性质。采用人工脱胶法提取大比目鱼心精子纤维（CHF）。根据标准程序，分析了纤维的物理、化学、结晶、热稳定性、拉伸和形态特性。化学分析结果表明，CHF中含有纤维素（59.82%）、半纤维素（16.75%）、木质素（9.3%）和蜡（1.3%）。CHF的结晶度指数为32.21%，热稳定性高达336℃。CHF的平均极限拉伸强度为20.7±1.0mpa。形态特征显示细胞壁之间的空隙较小，从而阻止了强度特性的降低。
