ABSTRACT:
According to the invention the material, in particular a textile, includes in its polymeric structure grafts forming complexes with at least one metal ion possessing recognized antiseptic activity. These grafts are formed by polymerization of unsaturated monomers with a complexing function, including the phosphate of ethylene glycol methacrylate or a polymerizable derivative of quinoline such as acryl 8-hydroxy quinoline. The process of preparation comprises a first step of grafting, for example by electronic irradiation of the material and impregnation with a bath of monomer, and a second step of impregnation of the grafted material with one or serveral baths containing the metal ion(s), such as copper, zinc, tin, mercury.
