Eugenol Treated Wetlaid Nonwoven Web for Antibacterial Applications
Keywords:
CHPTAC, eugenol, nonwoven, wet laying, wood pulpAbstract
Surface modification of cellulosic wood pulp was carried out using a cationic agent namely CHPTAC (3-Chloro-2-hydroxypropyl trimethyl ammonium chloride). Wet laying of fibers was carried out to develop a web comprising of normal and cationised wood pulp over which eugenol was treated by the dissolution of the essential oil in ethanol. The work focusses on sustained release of eugenol by surface modification of cellulosic wood pulp rather than bulk release. The sustained release of eugenol can be achieved by the formation of a bond between the quaternary ammonium group of cellulose and the hydroxyl group of eugenol oil which was confirmed using FTIR. The developed web offered lower thermal stability due to the volatile nature of the essential oil. The fibrous web comprising higher concentration of eugenol (30 wt%) offered higher antibacterial activity against E. Coli with a zone of Inhibition of 20 mm.
