Glycidyl methacrylate/monochlorotriazinyl-β-cyclodextrin mixture (GMA/MCT-β-CD) is grafted onto cotton fabric by an irradiation technique that uses linear electron beam radiation for initiating the grafting reaction. The obtained grafted fabric (cell-g-GMA/MCT-β-CD) is loaded with chlorohexidin diacetate (an antimicrobial agent) and subjected to several washing cycles. Grafted cotton fabrics (before and after loading with the antimicrobial agent) and control cotton fabrics are characterized for antimicrobial activity against different kinds of bacteria and fungi by using the diffusion disk method.
Grafted fabrics that are loaded with an antimicrobial agent show very good antimicrobial activity in comparison with control and grafted fabrics which are not loaded with an antimicrobial agent. The results in this study also demonstrate that GMA/MCT-β-CD grafted fabrics that are loaded with an antimicrobial agent retain a good deal of their antimicrobial activity after five washings. Good retention of antimicrobial activity is due to the cavities that are present in the cyclodextrin moieties which are used to host and keep the antimicrobial agent.
