  • USE OF SILICEOUS QUATERNARY AMINES IN DURABLE ANTIMICROBIAL TREATMENT OF TEXTILE FOR USE IN HEALTHCARE ENVIRONMENT
    Publication number: 20230407559
    Abstract: Compositions and methods are described that provide cellulosic and non-cellulosic fabrics with durable antimicrobial properties. Application of a coating that includes a biocidal binding agent, and optionally a hydrophilic polymer, to a fabric followed by drying and curing was found to provide antimicrobial properties that are retained through over 100 washings under aggressive hospital washing conditions. In addition, tactile properties and tear resistance of the treated fabrics are maintained or improved. The biocidal binding agent is selected to polymerize at low temperatures that are compatible with synthetic or semi-synthetic textiles.
