Abstract
This invention relates to the field of industrially launderable textile substrates possessing enhanced antifungal attributes. Specifically, the instant invention relates to industrially launderable textile substrates such as napery items, bar towels, shower curtains, and uniforms that possess antifungal properties, said antifungal properties being retained after multiple industrial laundering cycles.
Claims15
An industrially launderable textile substrate having durable antifungal characteristics after repeated industrial launderings, said textile substrate consisting essentially of polyester fibers, said fibers being formed into a textile fabric, wherein said textile substrate further comprises an antifungal treatment diffused into the polyester fibers, said antifungal treatment comprising diiodomethyl-4-tolylsulfone and zinc pyrithione or polyaminopropyl biguanide.
A process of making an industrial wash durable antifungal textile substrate, wherein said process comprises the steps of:
- providing a textile substrate, said substrate consisting essentially of polyester fibers
- applying an antifungal treatment comprising about 0.05% to about 2.4% owf of diiodomethyl-4-tolylsulfone (40% active) and about 0.2% to about 0.8% owf of zinc pyrithione (approximately 50% active) or polyaminopropyl biguanide (20% active) to said textile substrate, and
- heating said treated textile substrate to a temperature sufficient to cause the diiodomethyl-4-tolylsulfone (40% active) to penetrate the polyester fibers of said textile substrate, but below the temperature that would volatilize or decompose said diiodomethyl-4-tolylsulfone (40% active) or melt or damage said polyester fiber.
