摘要： A method of making synthetic polymer pellet feedstock having a high concentration of an anti-microbial agent includes the steps of: introducing a polymer into a mixing vessel; introducing a polysiloxane dispersant into the mixing vessel; introducing an anti-microbial agent comprised of a powdered metal material into the mixing vessel; heating and mixing the polymer, the polysiloxane dispersant and the anti-microbial agent to form a molten blend that exhibits a generally homogenous dispersal of the anti-microbial agent; extruding the molten blend to form filaments; and cutting the filaments to form metalized synthetic polymer pellet feedstock. The powdered metal material includes particles of silver in metallic or salt form measuring between about 2 micrometers and about 12 micrometers and particles of copper in metallic or salt form measuring between about 2 micrometers and about 12 micrometers.
