  • Patent number: 11827864
    Abstract: A wipe article includes a substrate, a cationic coating disposed on a surface of the substrate, distributed throughout the substrate, or both. The cationic coating contains a guanidinyl-containing polymer that is crosslinked and bound to the substrate. The substrate includes sponge, nonwoven fabric, or woven fabric. The wipes are useful for removing microorganisms from a microorganism-contaminated surface and also for reducing re-contamination of the cleaned surface or transfer to another surface of the removed microorganisms.
    Type: Grant
    Filed: October 19, 2022
    Date of Patent: November 28, 2023
    Assignee: 3M Innovative Properties Company
