Abstract
A method for producing a silver-bonded antimicrobial moist wound dressing. A silver-containing compound is added to a 0.1-30% aqueous solution of an alkaline solvent to dissociate silver ions from the silver-containing compound, dissolving CMC in water or an organic solvent to obtain a CMC solution, the silver ion-containing solution is mixed with the CMC solution so that the hydrogen ions (H+) of the hydroxyl groups of the CMC are replaced by the silver ions to prepare a silver-CMC compound, the silver-CMC compound is dispersed and absorbed in a medium, and the medium is dried.
