Abstract
The present invention is directed to surface functionalized fabrics, particularly those based on non-woven polypropylene, wherein the functional groups are capable of binding antimicrobial agents through ionic conjugation to control their release and prolong their antimicrobial activity. The invention also deals with Nylon 6 fabric that is complexed with iodine to control its release and to achieve prolonged antimicrobial activities. Similarly, polypropylene and cellulosic fabrics grafted with N-vinylpyrrolidone are disclosed. The N-vinylpyrrolidone can also complex with iodine to control its release and provide antimicrobial activity over desired periods of time.
