Characterization of Novel Natural Fiber from Saccharum Bengalense Grass (Sarkanda)

ABSTRACT

The exploration of novel natural fibers can contribute to expand their use in possible eco-friendly applications. In the current work, the physicochemical, thermal, tensile and morphological characteristics were tested for the fibers extracted from the stem of Saccharum Bengalense grass (SB). The results showed that fiber possesses good chemical constituents, namely, α- cellulose (53.45%), hemicellulose (31.45%) with lower lignin (11.7%) as confirmed from chemical analysis, its presence confirmed from Fourier Transform Infrared Spectroscopy (FTIR). Due to the presence of considerable chemical constituents, SB fibers showed good crystallinity index and tensile strength as confirmed from X-Ray diffraction analysis (XRD) and tensile test. Thermal stability was found using Thermogravimetric analysis (TGA), it revealed the SB fibers showed maximum degradation at 336°C and the char residue was 16.4%. Scanning Electron Microscopy (SEM) was used to study the morphological characteristics. Thus, SB fibers could be used as reinforcement in natural fiber-based polymer composites. This fiber utilization in composites may be suggested in potential applications like roofing sheets, bricks, door panels, furniture panels, interior paneling, storage tanks, pipelines, etc.

摨要

探索新的天然纤维有助于扩大其在可能的环保应用中的应用. 本文对从Saccharum Bengalense-grass-(SB) 茎中提取的纤维进行了理化、热、拉伸和形态特征的测定.结果表明，经化学分析证实，纤维具有较好的化学成分，即α-纤维素（53.45%）、半纤维素（31.45%），木质素含量较低（11.7%），傅立叶变换红外光谱（FTIR）证实了其存在.通过X射线衍射分析（XRD）和拉伸试验证实，由于存在大量化学成分，Sb纤维具有良好的结晶度指数和拉伸强度。用热重分析法（TGA）测定了锑纤维的热稳定性，结果表明，在336℃下，锑纤维的热稳定性最大，残炭率为16.4%.采用扫描电子显微镜（SEM）研究其形态特征.因此，锑纤维可作为天然纤维基聚合物复合材料的增强材料.这种纤维在复合材料中的应用可能被建议用于诸如屋顶板、砖、门板、家具面板、内部面板、储罐、管道等潜在应用.
