Characterization of Natural Cellulose Fiber from the Barks of Vachellia farnesiana

ABSTRACT

The need for environmental friendly materials have stimulated researchers to carry out works in natural fibers, which are substitute for human-made synthetic fibers in many lightweight medium load applications. In the present work, Vachellia farnesiana fiber was selected as a natural fiber. The obtained Vachellia farnesiana fibers were characterized for physical and chemical properties, Thermo Gravimetric Analysis (TGA), Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD) and, tensile strength. Scanning Electron Microscope (SEM) was used to capture its morphological characteristics. The outcome of the chemical analysis showed the weight percentage of ɑ-cellulose, hemicellulose, moisture content, wax, density and the same was confirmed by the output of the FTIR test. XRD test results showed that Vachellia farnesiana fiber had a crystallinity index of 13% and a crystal size of 31.89 nm. Thermal analysis showed a char residue of 28.71%.

摘要

对环境友好材料的需求刺激了研究人员在天然纤维领域开展工作，在许多轻质中载应用中，天然纤维代替了人造合成纤维. 在目前的工作中，法尼莎纤维被选为天然纤维. 对所制备的法氏Vachellia farnesiana纤维进行了物理化学性质、热重分析(TGA)、傅里叶变换红外光谱(FTIR)、X-射线衍射(XRD)和拉伸强度的表征. 用扫描电子显微镜(SEM)对其形态特征进行了观察. 化学分析的结果显示的重量百分比ɑ纤维素,半纤维素,水分含量,证实了蜡,密度和相同的傅里叶变换红外光谱学的输出测试. X-射线衍射测试结果表明，法氏Vachellia farnesiana纤维的结晶度指数为13%，晶体尺寸为31.89 nm. 热分析表明，残炭率为28.71%.
