Effect of different retting processes on yield and quality of banana pseudostem fiber

ABSTRACT

The main objective of this study is to develop a suitable technology to utilize banana pseudostem waste in an effective manner. The choice of a specific extraction method depends on the intended end uses of the fibers and hence different methods (mechanical, microbial, chemical, and enzymatic) were carried out to extract cellulosic fibers from Poovan variety and the chemical properties were investigated. The flexural and tensile properties of fibers were explored to analyze the suitability of fibers for different applications. Results obtained from these analyses confirmed that the tex value of chemical retted fiber was lesser than others. Scanning electron micrographs revealed that the surfaces of the chemically retted fibers were rougher than mechanically extracted fibers with an average diameter of 180 µm. The elemental composition of the chemical-treated banana pseudostem fibers was investigated by energy-dispersive X-ray analysis. Fourier transform infrared spectrum indicated the presence of similar functional groups in all the fiber samples.

摘要

本研究的主要目的是开发一种有效利用香蕉伪茎废料的技术。一个具体的提取方法的选择取决于最终的用途，因此纤维不同的方法（机械、生物、化学和酶法）进行了从Poovan品种和化学性质进行了提取的纤维素纤维。探讨了纤维的弯曲和拉伸性能，分析了纤维在不同应用场合的适用性。从这些分析得到的结果证实，化学浸渍纤维特克斯值较小。SEM照片显示化学沤制的纤维表面比粗糙机械提取纤维的180µM.能量色散X射线分析研究了处理香蕉假茎纤维的化学元素组成的平均直径。FTIR光谱表明在所有的纤维样品中都存在类似的官能团。
