Characterization of Alkali-Treated and Untreated Natural Fibers from the Stem of Parthenium Hysterophorus

ABSTRACT

In the current study, deals with the characterization of Parthenium hysterophorus fibers (PHF) extracted from its stem by manual retting process. Then, extracted fibers were alkali-treated, and its characteristics were compared with untreated one. The various behaviors of the alkali-treated and untreated PHF was studied using physical-chemical analysis, Fourier-transform infrared spectroscopy, X-ray diffraction, Thermogravimetric analysis, Tensile test, and Scanning Electron Microscopy. Results showed that alkali-treated PHF showed an increase in cellulose content by 8.9% than untreated PHF while the char residue was 38.5%. It also showed a better crystalline index, surface characteristics, and good tensile strength.

摘要

本文研究了用手工脱胶法提取枸杞茎中枸杞纤维的特性. 然后对提取的纤维进行碱处理，并与未经碱处理的纤维进行性能比较. 采用物理化学分析、傅立叶变换红外光谱、X射线衍射、热重分析、拉伸试验和扫描电镜等方法，研究了碱处理和未处理的PHF的各种行为. 结果表明，碱处理后的焦渣中纤维素含量比未处理的焦渣中纤维素含量增加8.9%，焦渣中纤维素含量增加38.5%. 同时显示出较好的结晶指数、表面特性和良好的拉伸强度.
