Extraction of natural cellulosic fibers from cornhusk and its physico-chemical properties

A natural long staple ligno-cellulosic fibers have been extracted from the cornhusks using an alkali treatment. Physico-chemical properties such as chemical composition, length, fineness, crystallinity, surface properties, etc. measured by standard methods are reported in this paper. The physico-chemical and morphological properties of the extracted cornhusk fibers are discussed in detail and compared with other cellulosic like cotton and ligno-cellulosic fibers such as jute. Scanning electron microscopy was used to study the morphological and cross-sectional view and energy dispersive X-ray and FTIR were used for the identification and quantification of elements, groups present in the cornhusk and other cellulosic and lignocellulosic fibers. In addition, fibers are characterized by thermo-gravimetric analysis. Results showed that morphological and physico-chemical behavior is more or less similar to other multicellular ligno-cellulosic fibers like jute.
