Abstract:
1. A method of forming an anti-microbial wiper capable of providing a liquid anti-microbial solution after multiple rinse cycles, the method comprising the steps of: providing a controlled release anti-microbial formulation comprising an anti-microbial agent and a polymer selected from the group consisting of acrylate polymers, styrene butadiene polymers, vinyl chloride polymers, methacrylate polymers, acrylic polymers, vinyl acetate polymers, and mixtures thereof, wherein said polymer is cross-linkable; adhering said formulation to an absorbent web containing fibers; and cross-linking said polymer; wherein said web retains liquid after each rinse cycle, and wherein said formulation releases sufficient anti-microbial agent into the retained liquid after each of at least five normal rinse cycles so that the retained liquid is an anti-microbial solution and said retained liquid is capable of disinfecting a hard surface that is wiped with said anti-microbial wiper.
