The present invention relates to a method for imparting durable antimicrobial activity to a substrate, in particular a textile. Acetate-free metal and peroxide antimicrobial treatment formulations are prepared by adjusting the pH of the metal salt in an aqueous hydrogen peroxide solution to about 7.5. This substrate is treated with the composition and dried to provide the treated substrate with antimicrobial activity. Zinc salts, ions, or complexes are suitable. [Selection] Figure 1 |
