The present disclosure generally relates to the field of antimicrobial coatings and, more specifically, to a method and an apparatus for applying antimicrobial coating.
Over the years, several solutions have been proposed to reduce the buildup of bacteria and/or microbes that can cause disease, fungus, mold, viruses, infection and/or irritation. However, the cost to implement and improve these designs have come with many shortcomings and led to inferior solutions in the market and the need to provide more desirable solutions.
Further, businesses that produce alternatives to previous solutions often charge more in excess than what the public is willing to pay for. A simple, affordable solution is still sought with a more achievable containment reduction efficacy than what the market currently offers.
Therefore, what is needed is a method and an apparatus for producing an antimicrobial coating with improved buildup reduction contaminant efficacy.
In an embodiment, a device for producing an antimicrobial coating on a surface of an object is provided. The device may include: one or more microfiber layers having one or more polyester layers and one or more foam layers; one or more mesh spacers to regulate air between the polyester layers and the foam layers; and an antimicrobial application unit for applying one or more antimicrobial coatings on the surface of the object.
In another embodiment, an apparatus for producing an antimicrobial coating on a surface of an object is provided. The device may include: one or more microfiber layers having one or more polyester layers and one or more foam layers; one or more mesh spacers to regulate air between the polyester layers and the foam layers; and an antimicrobial application unit for applying one or more antimicrobial coatings on the surface of the object.
In yet another embodiment, a method for producing an antimicrobial coating on a surface of an object is provided. The method includes: applying one or more polyester layers to a surface of an object; applying one or more foam layers to the surface of the object; joining the polyester layers with the foam layers; and applying one or more antibacterial coatings to the surface of the object.
In still another embodiment, a means for producing an antimicrobial coating on a surface of an object is provided. The means may include: means for applying one or more polyester layers to a surface of an object; means for applying one or more foam layers to the surface of the object; means for joining the polyester layers with the foam layers; and means for applying one or more antibacterial coatings to the surface of the object.
