The objective of the present research was to investigate the efficiency of alkali treatment in degumming of banana fibers. The fibers were exposed to alkali aqueous solutions at different concentrations changing from 5 to 20 wt%. The efficiency of the alkali treatments was analyzed with the help of optical observations, fiber diameter measurement, single fiber tensile test and determination of pectin component. The chemical, crystalline, thermal and morphological properties of the fibers were also examined. FTIR analyses proved the removal of non-cellulosic components such as hemicellulose and lignin after alkali treatment. Fiber diameter decreased with increasing alkali concentration. Tensile properties and crystallinity index are correlated with alkali concentration. However, the cellulose structure of the banana fiber was altered with alkali treatments at 15 and 20 wt% concentrations. Microscopic observations revealed the appearance of single elementary fibers from the fiber bundle of the banana. These experimental findings suggested that alkali treatment can play a promising role to prepare lignocellulosic fibers for textile applications.
