Abstract
A substantially flexible, dry matrix with antimicrobial properties is made from a matrix comprising natural or synthetic, woven, non-woven or knitted fibers, said matrix having been uniformly coated with an amount of a non-aqueous treatment solution sufficient to allow said matrix to retain its substantially dry characteristics. In a preferred embodiment, said non-aqueous treatment solution has between about 70% and 99% of at least one glycol compound, between about 1% and 15% of a PVP-iodine and optionally between about 0 and 15% of a non-ionic surfactant. Also, skin is treated to prevent disease, such as the disinfecting of teats on dairy cows during milking, by wiping the skin with the article.
