VARIATION IN LIGNO-CELLULOSIC PROPERTIES OF JUTE FIBER AND STICK BASED ON PLANT POSITION

This study investigated the ligno-cellulosic properties of jute fiber and jute stick, focusing on variations along different plant sections (bottom, middle, and top). Results for jute fiber indicated that cellulose content was highest at the top (64.57%) and lowest at the bottom (63.18%), while lignin showed the opposite trend, being highest at the bottom (16.07%) and lowest at the top (15.27%). Hemi-cellulose, ash, fat/oil, moisture, and other components in jute fiber did not exhibit significant variations across sections. Similarly, jute stick displayed higher cellulose at the top (47.87%) and lower cellulose at the bottom (46.98%), with lignin following the inverse pattern (25.27% at bottom, 23.91% at top). Hemi-cellulose, ash, fat/oil, moisture, and others in jute stick also showed no significant differences among sections. A comparative analysis revealed that jute fiber contained significantly higher cellulose (~63-64%) and lower lignin (~15-16%) than jute stick (~46-47% cellulose; ~24-25% lignin). Conversely, jute stick had a higher hemi-cellulose content (~25-26%) compared to jute fiber (~18%). These findings highlight distinct compositional profiles between jute fiber and jute stick, as well as gradients along the plant length, which are crucial for optimizing their utilization in various industrial applications, including textiles, paper, bio-energy, and composite materials. Key words: Jute, cellulose, lignin, plant position.
