Abstract
Active agent infused linear materials are provided with an infused surface that is infused with one or more dye molecules as well as methods of production. A method of forming an active agent infused linear material also as provided herein includes passing a substantially linear polymeric substrate through a linear substrate infusion chamber, and contacting the linear substrate with the liquid infusion solution at an infusion temperature and for an infusion time effective to infuse the one or more active molecules into or onto a surface of the linear substrate, thereby forming an active agent infused linear material. The liquid infusion solution includes one or more active molecules.
