For the application of crease resistant finish the chitosan, citric acid, silicon softener and catalyst were used. Before application of finish the different condition such as drying time, drying temperature, curing time, curing temperature and concentrations of chemicals along with M: L ratio were standardized. The optimized concentrations and conditions were the 4% chitosan, 10% citric acid, 6% catalyst, and 6% silicon softener ,4 minute drying and curing time, treatment time 15 minute, 100 0 C drying temperature, 170 0 Ccuring temperature,. The finish was applied on the scoured cotton fabric with optimized proportion of chemicals maintaining the 1:20 m: l ratio by using the padding mangle. assessment of the crease recovery properties and antibacterial property was done .It was found that there was increase in the crease recovery angle and fabric crease recovery in addition to it the crease resistant finish showed good bacterial percent reduction. Further the change in the other physical properties of controlled, treated and washed fabrics was assessed. It was found that the fabric count, weight per unit area, thickness, bending length of treated fabric increased hence air permeability, elongation and tensile strength of fabric decreased but to an acceptable level. It was also noticed that all these physical properties deceased except air permeability and elongation with progressive washing cycles. The treated cotton fabric showed good bacterial resistance after 20 washing cycles. The finish is safe and non toxic for use. The treated fabrics will not only provide health benefits to the common masses but will also benefit the workers who are engaged in finish sector of textile industries. Crease resistant finish with antibacterial property will add value to cotton so the cultivation, production and export of cotton will also boost.enCrease resistant finish, chitosan, citric acidThesis
