Characterization of New Cellulosic Fibers Obtained from Zingiber Officinale

ABSTRACT

Zingiber officinale (known as ginger), a natural flowering plant of Zingiberaceae family, was taken to investigate its possible utilization in a textile material. Zingiber officinale fibers (ZOFs) were obtained from the plant root. The cellulose, hemicellulose, and lignin contents of ZOFs were determined. Elemental analysis of ZOFs was carried out with energy dispersive X-ray analysis (EDX) instrument. Surface morphology of fibers was investigated with a scanning electron microscope (SEM) instrument. The chemical functional groups of ZOFs were confirmed with Fourier transform-infrared spectroscopy (FT-IR). The crystalline structure of ZOFs was analyzed with X-ray diffraction (XRD), and then the crystallinity index was calculated as 78.81%. In addition to this, mechanical properties of ZOFs were investigated with Shimadzu Ag-X machine. The EDX and FT-IR results show that ZOFs have cellulosic structure. Furthermore, it was obtained that ZOFs have rough surface structure and the thickness is approximately 155 µm. The physical properties of ZOFs are substantial enough for its usage as a textile fiber.

摘要

摘要研究了姜科天然开花植物姜黄(生姜)在纺织材料中的应用. 从该植物的根中提取了生姜纤维(ZOFs). 测定了生姜纤维中纤维素、半纤维素和木质素的含量. 采用能量色散X-射线分析仪(EDX)对生姜纤维进行了元素分析. 用扫描电子显微镜(SEM)对纤维的表面形貌进行了研究. 采用傅里叶变换-红外光谱法(FT-IR)确定了生姜纤维的化学官能团. 用X-射线衍射分析了生姜纤维的结晶结构，计算了其结晶度指数为78.81%. 此外，还用岛津Ag-X机对生姜多酚纤维的力学性能进行了研究. 能量色散x射线分析和傅里叶变换红外光谱分析结果表明，生姜纤维具有纤维素结构. 此外,它获得了生姜纤维有粗糙表面结构和厚度约155µm. 生姜纤维的物理性能足以作为纺织纤维使用.
