Abstract
Durable antimicrobial treatments for high pressure treatments (such as package dyeing) for specific dyed yarns for further incorporation within textile fabrics are provided. Such treatments preferably comprise silver ions, particularly as constituents of inorganic metal salts or zeolites. This particular treatment requires the presence of a resin binder as a component of the dye bath formulation admixed with the silver-ion antimicrobial compound, the formulation then forced through a target yarn spool in order to provide a finish over substantially all of the target yarn. The yarn may then be knit, woven, pressed, laid-in, etc., into a textile fabric exhibiting antimicrobial properties. Such a treatment has been found to be extremely durable on such substrates; after a substantial number of standard launderings and dryings, the treatment does not wear away in any appreciable amount and thus the substrate retains its antimicrobial activity. The particular treatment method, as well as the treated textile fabrics, are also encompassed within this invention.
