Abstract
An antimicrobial composite which comprises a first, liquid-permeable layer which is substantially completely bonded to a second liquid-absorbing layer. The first layer comprises a coating of at least one antimicrobial metal as such on the side which is bonded to the second layer. Substantially no antimicrobial metal in elemental form is present on exterior surfaces of the composite.
Claims10
An antimicrobial composite, wherein the composite comprises a first, liquid-permeable layer which is a polyethylene mesh that is substantially completely laminated to a second liquid-absorbing layer to provide a peeling strength between the first layer and the second layer of at least about 0.15 N/cm, which mesh comprises a coating of not more than about 450 mg/m2 of silver in elemental form on a side which faces the second layer, and wherein substantially no silver in elemental form is present on exterior surfaces of the composite.
An antimicrobial composite, wherein the composite comprises a first, liquid-permeable layer which is a polyethylene mesh that has openings having an average size of from 250 μm to 1400 μm to provide an open area of from about 15% to about 60% of a surface area of the first layer, which mesh is substantially completely laminated to a second liquid-absorbing layer to provide a peeling strength between the first layer and the second layer of at least 0.15 N/cm, and comprises a coating of not more than about 80 mg/m2 silver in elemental form on a side which faces the second layer, and wherein substantially no silver in elemental form is present on exterior surfaces of the composite.
