The work is focused on the study of antibacterial fabrics, which can be applied in many different sectors. Cotton and polyamide 6,6 fabrics were treated with chitosan, a non-toxic antibacterial biopolymer that allows the dyeing of the textile substrate, and tested against Gram-positive and Gram-negative bacteria. The objective is to evaluate the efficiency over time of the chitosan antibacterial action by performing the standard antibacterial tests at different contact times. Since the fabrics must keep antibacterial property preserved also after dyeing and washing, the experiments were executed on dyed and washed chitosan-treated fabrics.
