Abstract
A polymeric linear substrate is provided with one or more active agents infused into the linear material to a depth less than the 100 micrometers, optionally where the polymeric linear substrate has a cross sectional dimension that does not exceed 2 centimeters. The polymeric material may include a polyamide, a polyester, polyvinylchloride, or polycarbonate. Also provided are systems for infusing a linear substrate with one or more active agents that includes a dye supply providing a dye; a process tank connected to the dye supply and providing a reservoir of a liquid infusion solution including the dye through the linear substrate infusion system; and a process chamber fluidly connected to the process tank for contacting the liquid infusion solution with a linear substrate effective to infuse the dye into a surface of the linear substrate.
