Biocidal polyester fabrics, fibers and other materials, and methods of preparation. Heterocyclic N-halamine precursor moieties are covalently linked to the polyester material. The fabrics or fibers obtain antimicrobial activity after washing with a source of oxidative halogen such as a chlorine bleach by conversion of the precursor moieties into N-halamine functionalities. The antimicrobial activity can be repeatedly regenerated by further washing with aqueous oxidative halogen. The biocidal polyester fabrics, fibers, and other materials will be effective in reducing, or eliminating entirely, pathogenic and odor-causing microorganisms.
