Effect of chemical treatments on Ampelocissus Cavicaulis fiber

Ejikeme Patrick C. N., Ejikeme Ebere M. and Nwosu David C

ABSTRACT The tensile strength of Ampelocissus cavicaulis fiber was enhanced by chemical treatment with sodium hydroxide, acetic anhydride, nitric acid, and zinc chloride. Effects of concentrations of the chemicals and pretreatment time on the tensile strength of fiber were studied. It was observed that tensile strength of the fiber was increased as the chemical concentrations and pretreatment time were increased to a point that further increase led to decrease in tensile strength of the fiber. The SEM analysis confirmed that the chemical treatments succeeded in removing the surface impurities and lignin components of the fiber which resulted to smooth surfaces of the treated fiber with attendant increase in tensile strength. Sodium hydroxide had highest effect on the fiber, followed by acetic anhydride, nitric acid, and lastly, zinc chloride. Keywords:- Acetic anhydride, ampelocissus cavicaulis, nitric acid, sodium hydroxide, zinc chloride
