Different polymers were used as antimicrobial finishing agent in textile application. Different methods were used to functionalize polyvinylamine, chitosan and cylcodextrin onto fibres. The finished fabrics were chracterized by different analytical tools. In addition the antibacterial activity of the modified surfaces was evaluated by Tetrazolium-Formazan test. A surface test agent (Toluol) was complexed by ß-Cyclodextrin and its deliverey was evaluated by olfactometry.
