Abstract
A fabric delivers active ingredients to a surface when the fabric includes a moist-vapor porous combination of fabric materials, and the fabric comprises at least 0.5% by total weight of at least one layer of the fabric of a superabsorbent polymer fiber. The superabsorbent polymer fiber contains an absorbed aqueous reservoir of an aqueous solution carrying the active ingredients. The superabsorbent fiber has a coating on its surface of an aqueous penetrable layer through which a liquid in the absorbed aqueous reservoir can migrate or flow, carrying the active ingredients onto an exposed surface of the superabsorbent polymer fiber, so that the active ingredients on the surface of the superabsorbent polymer can react or interact with an environment in contact with the active ingredients on the superabsorbent polymer fiber surface.
