摘　　要：Pathogenic bacteria can proliferate rapidly on porous fabrics to form bacterial plaques/bioflms,resulting in potential sources of cross-transmissions of diseases and increasing cross-infection in public environments.Many works on antibacterial modifcation of cotton fabrics have been reported,while very few works were reported to endow poly(ethylene terephthalate)(PET)fabrics with non-leaching antibacterial function without compromising their innate physicochemical properties though PET is the most widely used fabric.Therefore,it is urgent to impart the PET fabrics with non-leaching antibacterial activity.Herein,a novel N-halamine compound,1-chloro-3-benzophenone-5,5-dimethylhydantoin(Cl-BPDMH),was developed to be covalently bonded onto PET fabrics,rendering non-leaching antibacterial activity while negligible cytotoxicity based on contact-killing principle.Bacterial was easily adhered to Cl-BPDMH fnished PET fabrics,and then it was inactivated quickly within 10 s.Furthermore,the breaking strength,breaking elongation,tearing strength,water vapor permeability,air permeability and whiteness of Cl-BPDMH fnished PET fabrics were improved obviously compared to raw PET fabrics.Hence,this work developed a facile approach to fabricate multifunctional synthetic textiles to render outstanding and rapid bactericidal activity without compromising their physicochemical properties and biocompatibility.
