Abstract

ABSTRACT: This study investigates the morphological changes and tensile properties of Alfa fibers extracted mechanically after two treatments namely water retting and alkali treatment. The Scanning Electron Microscopy technique is used in this experimental work. The main observation reveals the decrease of noncellulosic component in the fibers which is inversely proportional to the concentration of sodium hydroxide solution in the case of the alkali treatment. Tensile tests were carried out using tensile machine for determining the tensile properties mainly the tensile strength and the elastic modulus. The tensile strength and young's modulus of retted fibers are assumed constant. The results relative to the alkalized fibers show an improvement of tensile strength and young's modulus and are proportional to the sodium hydroxide concentration up to 14%.
