Special dyes could make fabric an MRSA killer

The mordant-dyed non-mercerized knitted cotton samples adsorb larger amounts of copper ions directly bound to cotton during pre-mordanting. The ability of the copper ions bound to cotton and to the dye during pre- or post-mordanting is higher than that of the copper ions contained in the dye molecule. In addition, mordant-dyed cotton fabrics exhibited antibacterial activity against Staphylococcus aureus and MRSA, and thus had potential as deodorizing/antibacterial fabrics.
