Abstract

Le problème à résoudre par la présente invention est de fournir un revêtement de masque antivirus ayant pour fonction de prévenir une infection par des pathogènes tels que des virus et des germes.　La solution selon l'invention porte sur un revêtement de masque antivirus qui comprend un tissu non-tissé d'oxyde de cuivre ayant une activité antivirale, des fentes étant disposées sur les extrémités gauche et droite à travers lesquelles les ficelles des masques sont passées. Lorsque le revêtement antivirus est fixé à un masque à l'aide des fentes, il est possible d'empêcher que les virus infectieux restent sur la surface du masque et que le masque lui-même soit une voie d'infection. De plus, lorsque le revêtement est monté sur un masque en tissu qui peut être lavé et reporté et qui présente une capacité d'élimination de virus inadéquate, une capacité d'élimination de virus fixe peut être conférée au masque en tissu.
