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

对环保材料的需求刺激了研究人员在天然纤维方面开展工作，在许多轻质中等负载应用中，天然纤维可替代人造合成纤维。在目前的工作中，Vachella farnesiana纤维被选为天然纤维。获得的金莲花纤维的物理和化学性质、热重分析 (TGA)、傅里叶变换红外光谱 (FTIR)、X 射线衍射 (XRD) 和拉伸强度进行了表征。扫描电子显微镜 (SEM) 用于捕捉其形态特征。化学分析的结果显示了 ɑ-纤维素、半纤维素、水分含量、蜡、密度的重量百分比，FTIR 测试的输出也证实了这一点。XRD测试结果表明，Vachella farnesiana纤维的结晶度指数为13%，晶体尺寸为31.89 nm。热分析显示有 28.71% 的焦炭残留物。
