Abstract
A wiper that provides a controlled release anti-microbial agent has a substrate layer to which the anti-microbial agent is adhered. In addition, the wiper will have one or more laminate layers, at least one of which will be absorbent. Various anti-microbial agents such as silver containing additives, calcium hypochlorite, and chlorine dioxide generating compounds may be employed. The substrate layer may be a poly(ethylene vinyl acetate) meltblown web and the laminate layer may be a hydroentangled composite absorbent fabric.
