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.

In the present scenario, the searching for novel plant fibers able to be used as reinforcement of polymer composites is highly appreciable. This study deals with extraction and characterization of Eleusine indica grass fibers extracted from its stem by manual retting process. From this study, it was found that the Eleusine indica has higher cellulose of 61.3 wt% content, density of 1143 kg/m3, average tensile strength and Young's modulus equal to 22 MPa and 10.75 GPa, respectively. From the XRD studies, it was noted that the Crystallinity Index (CI) of Eleusine indica was 45%. The surface morphology of Eleusine indica grass was examined using a Scanning Electron Microscope (SEM) and Chemical functional group were confirmed by Fourier transform infrared spectroscopy (FT-IR). The thermal stability of EIF was evaluated using TG and DTG curves from Thermogravimetric (TG) analysis. The characterization results confirmed that Eleusine indica grass could be used for the production of sustainable fiber-reinforced polymer composites. [ABSTRACT FROM AUTHOR]
