Characterization of Optimally Alkali-treated Natural Cellulosic Fiber Extracted from the Stem of Cissus Vitiginea Plant

ABSTRACT

New novel natural fibers are being identified and reported to the research community in the recent decades. Selective techniques to modify the properties of natural fibers have also been focused and investigated. In the present work, Cissus vitiginea stem fibers (CVSF) have been chosen and optimally treated using aqueous alkali solution and tested for the improvement in the The treated C. vitiginea has been characterized to report the essential properties such as physical properties, crystalline properties, chemical composition, thermal stability characteristics, etc., The chemical composition analysis revealed that the cellulose contents in the treated CVSF has been increased by 10.71% after the treatment. The crystallinity index value of the treated CVSF (38.43%) got improved by 26% over the raw fibers as a result of the alkali treatment. The tensile strength of the treated CVSF has been reported as 376.4 ± 13 MPa. The elimination of the wax and other impurities from the surface of the fibers has been confirmed using the SEM micrographs. The results of all the carried out experimentation confirmed that the properties of the CVSF have got significantly improved, and the treated CVSF can be suggested to be used for making thermo and thermo set plastic green composites.

摘要

近几十年来, 新的天然纤维正在被鉴定并向研究界报告. 对天然纤维改性的选择性技术也进行了重点研究. 在本研究中, 选择了葡萄藤茎纤维 (CVSF), 并使用碱溶液对其进行了优化处理, 并测试了其基本性能的改善, 如物理性能、结晶性能、化学成分、热稳定性等. 化学成分分析表明, 处理后CVSF中的纤维素含量增加了10.71%. 碱处理后的CVSF (38.43%) 的结晶指数比原纤维提高了26%. 据报道, 经处理的CVSF的抗拉强度为376.4±13 MPa. 使用SEM显微照片证实, 蜡和其他杂质已从纤维表面清除. 所有实验结果均证实, CVSF的性能得到了显著改善, 并且经过处理的CVSF可用于制备热固性塑料和热固性塑料绿色复合材料.
