Studies on physical properties of wine palm and Roselle natural fibers

ABSTRACT

In this work, fiber strands of Wine Palm (Caryota urens) and Roselle (Hibiscus sabdariffa) plants were extracted and characterized. The extracted fiber strands were given water treatment for making comparisons with its dried counterpart. Techniques such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM)-energy dispersive X-ray spectroscopy (EDX) were used to determine the micro structure, morphological properties and chemical compositions. Mechanical properties were studied using universal testing machine (UTM). XRD results indicate an increase in crystallinity of the fiber strands with water treatment and FTIR Spectroscopy reveals the variation of functional groups in these fibers. SEM analysis indicates smoothening of the surface on water treatment. The fineness of these fiber strands was found to be 372.18 denier and 13.63 denier respectively for CU and HS fibers. UTM results confirm that tensile strength increases on water treatment for both the fibers. These fibers have competitive advantages when evaluated with other natural fibers.

摘要

在这项工作中，酒棕榈纤维束 (Caryota Urens) 和Roselle (Hibiscus Sabdariffa)植物提取和特征。对提取的纤维束进行水处理，与干燥后的纤维进行比较。利用X射线衍射 (XRD)、傅立叶变换红外光谱（FTIR）和扫描电子显微镜 (SEM)、能量色散X射线能谱（EDX）等手段对微结构、形貌特征和化学成分进行了测定。利用万能试验机的机械性能进行了研究 (UTM), X射线衍射结果表明，在纤维束与傅里叶变换红外光谱法水处理和光谱揭示了在这些纤维官能团的变化，结晶度增加。扫描电子显微镜分析表明, 平滑的表面对水处理。这些纤维束的细度为372.18旦、13.63旦分别为CaryotaUrens 和 HibiscusSabdariffa纤维。万能试验机的结果证实了两种纤维在水处理过程中的拉伸强度都有所提高，与其他天然纤维相比，这种纤维具有竞争优势
