Extraction and characterization of natural cellulosic fiber from Passiflora foetida stem

This article presents a comprehensive characterization study of natural cellulosic fiber extracted from Passiflora foetida vine stem. The chemical composition of the obtained P. foetida fibers (PFFs) comprised high cellulose (77.9 wt%) and low lignin (10.47 wt%) content and had distinctly higher crystallinity (67.36%) of cellulose, which was determined by an X-ray diffractometer. The PFFs exhibited good tensile strength of 248?942 MPa associated with elongation (1.38?4.67%) during tensile testing. Thermogravimetric analysis revealed that the PFFs are thermally stable up to 320°C with kinetic activation energy of 85.46 kJ mol^?1; hence they ensure their suitability as a reinforcing phase in composites for potential applications.
