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. The inventive triclosan esters do not easily wash off and do not lose their antimicrobial characteristics upon contact with bleaching agents.
