A reactive melamine derivative, 2-amino-4-chloro-6-hydroxy-s-triazine (ACHT), was covalentlybound onto cotton cellulose through nucleophilic substitutions. Four treatment methods, includingcold-pad-batch, pad-dry-cure, pad-steaming, and exhaustion, were employed in the reactions.The pad-dry-cure method provided the highest reaction efficiency. The mechanical propertiesof the treated fabrics were characterized, and the reaction mechanism was further discussed.Upon chlorine bleaching treatment, the covalently bound ACHT moieties could be transformedinto chloromelamine derivatives, providing potent, durable, and rechargeable antimicrobialfunctions against 106-107 CFU/mL of drug-resistant gram-negative and gram-positive bacteriaunder both waterborne and airborne conditions.
