Effect of Harvesting Time on the Fiber Yield and Characterization of Jute Fiber

ABSTRACT

The variation in the interior and exterior properties of jute fiber depends on harvesting time. But jute fibers to convert diversified products require certain qualities. The purpose of this study is to determine fiber yield and characterize the physico-chemical, thermal, and mechanical properties of jute fiber at different harvesting times. Field data were analyzed with the help of “Statistix 10” software, and assessment of jute fiber characterization at different harvesting times was done using chemical analysis, Stelometer, fiber fineness analysis system, photovolt meter, Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA). According to the results, the maximum fiber yield (3.53 ton/ha) and whiteness or color lightness (40.76%) were obtained at 120 days of harvesting time. The strength (gm/tex) 51.05, diameter (μm) 34.13, and cellulose content (%) 65.58 of 60 days’ sample was good when compared to other days’ samples. FTIR assessment of the jute fiber reveals the presence of functional groups. The 105 days’ sample has highly thermal stability when compared to other samples. This research will be helpful to select proper raw jute fiber for its end users in potential variegated jute products.

摘要

黄麻纤维内部和外部性能的变化取决于收获时间. 但黄麻纤维转化为多样化产品需要一定的品质. 本研究的目的是测定黄麻纤维的产量, 并表征不同收获期黄麻纤维的物理化学, 热性能和机械性能. 借助“Statistix 10”软件对现场数据进行分析, 并使用化学分析, 测厚仪, 纤维细度分析系统, 光电伏特计, 傅里叶变换红外光谱 (FTIR) 和热重分析 (TGA) 对不同收获时间的黄麻纤维特性进行评估. 结果表明, 在收获120天时, 纤维产量 (3.53吨/公顷) 和白度或颜色亮度 (40.76%) 最高. 与其他天数的样品相比, 60天样品的强度 (gm/tex) 51.05, 直径 (μm) 34.13, 纤维素含量 (%) 65.58良好. FTIR对黄麻纤维的评估揭示了官能团的存在. 与其他样品相比, 105天的样品具有高度的热稳定性. 本研究将有助于为潜在的杂色黄麻产品的最终用户选择合适的黄麻原纤维.
