Abstract: A process for imparting long-lasting antimicrobial properties to fabrics is disclosed which entails the diffusion of triclosan esters within each individual fiber of a textile. One preferred method is performed in a standard jet dye bath which requires a high range of temperatures to effectively color fabrics. Dyeing in this manner also involves diffusing compounds within individual fibers; thus, this manner of incorporating dyestuffs and colorants within textile fabrics provides a compatible and effective vehicle for simultaneously introducing triclosan esters within such textile fibers, also. A dye bath application is not required, however, as any procedure which allows contact between a triclosan ester derivative and a fabric at a sufficient temperature and for a sufficient time to effectuate diffusion of the ester within each individual fiber of the fabric is also contemplated within this invention.
