Abstract
In various aspects, the present disclosure relates to fibers and fabric media comprising photoactivatable agents and to fibers and fabric media that are photoactivatable by photoactivation of the photoactivatable agents. In some instances, the fibers and the fabric media have photoactivatable agents present on their surface (e.g., the fiber/fabric is coated or sprayed with the photoactivatable agents or the fiber/fabric is dipped into a composition or a formulation comprising the photoactivatable agent). In other instances, the photoactivatable agents are incorporated into the materials making the fibers (e.g., the photoactivatable agents are mixed/compounded with the materials making the fibers). The photoactivatable fibers of the present disclosure comprise at least one thermoplastic polymer and at least photoactivatable agent that absorbs and emits light between about 400 nm and about 800 nm.
