摘要：
A face mask including a face-contacting layer, an outer cover layer, a polymeric microfiber mat disposed between the face-contacting layer and the outer cover layer, and a non-woven fibrous mat disposed between the face-contacting layer and the outer cover layer. The non-woven fibrous mat includes polymeric fibers and a surface energy reducing agent. The face-contacting layer, the cover layer, the polymeric microfiber mat, and the non-woven fibrous mat cooperate with each other to allow gas to pass through the mask while inhibiting the passage of liquid through the mask.
