Articles and methods for treating textiles and other materials with an antimicrobial compound during laundry and/or drying cycles. The articles include a porous substrate and a core composition that is releasably associated with the substrate and that includes a metal ion having antimicrobial activity. Methods include the use of the articles in laundry and/or drying cycles to provide antimicrobial treatment of the textiles and materials.

Articles and methods for dispensing metal ions into laundry systems

Articles, compositions, and methods for treating textiles and other materials with an antimicrobial compound during laundry and/or drying cycles are described. The articles and compositions include a metal ion having antimicrobial efficacy. Methods include the use of the articles and compositions in laundry and/or drying cycles to provide antimicrobial treatment of the textiles and materials.

Dispensing of metal ions into batch laundry washers and dryers

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 is described. 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.

Systems and processes for treating textiles with an antimicrobial agent

An antimicrobial supply system employs a process water supply and incorporates a metallic ion supply connected to the process water supply to provide a high ion concentrate to an output. A dilution reservoir is connected to the metallic ion supply output and has an input from the process water supply. A pump is connected to an output of the reservoir. A manifold connected to the pump provides a dilute concentrate to at least one washing system. An electronics control module is connected to a first flow controller between the process water supply and the metallic ion supply and a second flow controller between the metallic ion supply and the reservoir for dilution control establishing a desired metallic ion concentration.

Antimicrobial fabric application system

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.
