Nanosized Chitosan Hydrogels Containing Sumac Extract for Antimicrobial Biofinishing of Cotton Fabric, Preparation and Characterization

The objective of this research was to formulate chitosan nano hydrogels based on mini-emulsion method. Sumac extract was obtained by maceration sumac cortex in water. The antimicrobial effects of finished fabrics and sumac extract against two pathogenic microorganisms, Staphylococcus aureus and Escherichia coli, the particle size, were then observed by using different methods like antimicrobial test and SEM. Antimicrobial potential of hydrogels was influenced significantly by the concentration of sumac extract. Chitosan nanoparticles with about 60nm in diameter were fabricated via emulsion method. This approach opens new horizons beyond the current application of hydrogels for future investigations.
