Abstract
Specific transfer methods and articles to impart a metal-ion based antimicrobial finish to recipient textile surfaces. Such treatments preferably comprise silver ions, particularly as constituents of inorganic metal salts or zeolites. In particular, the inventive method involves the application of a solid, inorganic antimicrobial material to a donor substrate (such as a dryer sheet), and the subsequent placement of such a substrate within a tumble drying machine containing textile fabrics and operating the machine. The donor substrate, upon contact with the recipient textile fabrics, transfers antimicrobially effective amounts of the metal-ion based compounds to such recipient fabrics thereby imparting at least a temporary antimicrobial finish over at least a portion of such fabrics. The donor substrates, with either the antimicrobial compound alone or mixed with standard tumble dryer additives (such as perfumes, fabric softeners, fiber lubricants, and the like) are also contemplated within this invention.
