A novel cellulosic fibre was extracted from the peduncle portion of the fish tail palm tree and the extracted fish tail palm fibre was treated with different concentrations (1%, 5%, and 9%) of silane solution. The characteristic analysis on chemical, functional, mechanical and surface property of the extracted fish tail palm fibres were investigated through chemical composition analysis, Fourier Transform InfraRed spectroscopy (FT-IR), single fibre tensile test, and Scanning Electron Microscopy (SEM). Chemical analysis results indicate that silane treatment improved the cellulose content of the fish tail palm fibre. The highest cellulose content of 72.51% was observed in the 9% silane treated fish tail palm fibre. Also, it improved crystallinity index value of 62.5% for 5% silane treated fibre, which is confirmed through the X-ray diffraction analysis. FT-IR result indicates the removal of hemicellulose at characteristic wavelength of 1745 cm for 5% silane treated fish tail palm fibre. Tensile property of the silane treated fish tail palm fibre (1, 5, and 9%) shows an increased tensile strength of 7.3%, 12%, and 6.6% as compared to raw fish tail palm fibre. Moreover, this type of novel natural fibres can reduce the cost while offering competent performance during the polymer-based product development.
从鱼尾葵树的叶柄部分提取了一种新型纤维素纤维，并对提取的鱼尾葵纤维进行了不同浓度（1%、5%和 9%）的硅烷溶液处理。通过化学成分分析、傅里叶变换红外光谱（FT-IR）、单纤维拉伸试验和扫描电子显微镜（SEM）对提取的鱼尾葵纤维的化学、功能、机械和表面性能进行了特征分析。化学分析结果表明，硅烷处理提高了鱼尾葵纤维的纤维素含量。在 9%硅烷处理的鱼尾葵纤维中观察到最高的纤维素含量为 72.51%。此外，通过 X 射线衍射分析证实，5%硅烷处理纤维的结晶度指数值提高了 62.5%。FT-IR 结果表明，5%硅烷处理的鱼尾葵纤维在特征波长 1745 cm 处去除了半纤维素。与原鱼尾葵纤维相比，硅烷处理的鱼尾葵纤维（1%、5%和 9%）的拉伸性能显示出拉伸强度分别提高了 7.3%、12%和 6.6%。此外，这种新型天然纤维可以降低成本，同时在聚合物基产品开发过程中提供相当的性能。
