Abstract

The present study focused on extraction of Lonchocarpus cyanescens (L. cyanescens) fiber (LCF) and the physico-chemical properties of the obtained fiber. The fiber was extracted by manual and traditional rating methods, treated with sodium hydroxide, and characterized to determine its performance properties. The chemical composition of cellulose, hemicellulose, and lignin was determined according to the acid detergent, neutral detergent, and Klason methods, respectively. The results show significant quantities of cellulose (33%), hemicellulose (30%), and lignin (24%) in the studied fibers. LCF exhibited a porous multicellular and poly lamellate network structure (FE-SEM) with a crystallinity index of 56.5%. The thermal stability using TGA analysis indicates that the maximum and main degradation temperature is 325°C. The crystallinity, thermal stability, and opening of micropores on the fiber surface have been increased after alkaline treatment. As a conclusion drawn, LCF fibers could be used as potential reinforcement in polymer matrices for a variety of applications where porous, multicellular, and poly lamellate network structure is needed.
