ELECTROSTATICALLY CHARGED FACE MASK AND METHOD FOR MAKING THE SAME Abstract A method for electrostatically charging the body portion of a face mask, said body portion comprising a first air permeable facing layer, a filtration medium having at least two individual layers of melt blown thermoplastic fibers, and a second air permeable facing layer. The method involves making a first laminate of the first facing layer and one of the individual melt blown layers and electrostatically charging the same. A second laminate of the second facing layer and another individual melt blown layer is made and superposed on the first laminate to form a four-ply laminate in which the individual melt blown layers are in face-to-face contact. The four-ply laminate is then electrostatically charged. Main body portions for face masks as well as face masks comprising the electrostatically charged body portion are claimed.
