Abstract
According to an aspect of the present disclosure, a method of treating a textile with an antimicrobial agent over a plurality of laundry cycles each including a wash cycle and a treatment cycle. The method includes (a) receiving a textile in a wash system for a first laundry cycle, (b) initiating a wash cycle comprising a detergent, (c) initiating a post-detergent treatment cycle comprising dosing the textile with a solution having a predetermined concentration of an antimicrobial agent that comprises a metallic ion, and (c) repeating steps (a)-(c) for each of a plurality of additional laundry cycles. The predetermined concentration is insufficient to achieve a predetermined antimicrobial efficacy for the textile due to the first laundry cycle alone but sufficient to achieve the predetermined antimicrobial efficacy for the textile due to a combination of the first laundry cycle and one or more of the plurality of additional laundry cycles.
