ABSTRACT:
A process by which 1-hydroxy-2-pyridinethione (pyrithione) can be deposited in cellulosic textiles in a water-insoluble form is disclosed. A polyamine is used to keep a zinc complex of pyrithione in aqueous solution prior to and during its application to textiles; when the solution also contains urea, heating fabric impregnated with the solution converts the pyrithione complex to an insoluble material. Fabric treated by the process has high bacteriostatic and fungistatic activity, and retains antimicrobial properties after repeated laundering.
