Abstract

La présente invention concerne un masque dans lequel un corps principal de masque (20) est configuré à partir d'une feuille de tissu non tissé externe (30), une feuille de tissu non tissé contenant du parfum (40), une feuille de tissu non tissé externe (50) et une feuille de revêtement (60). Lorsque le masque est porté, la feuille de tissu non tissé interne (30) est située sur le côté du porteur. La feuille de tissu non tissé contenant du parfum (40) contient des microcapsules dans lesquelles un parfum est encapsulé. La feuille de tissu non tissé interne (30) est conçue pour présenter une perméabilité à l'air supérieure (résistance à la perméation à l'air inférieure) à la feuille de tissu non tissé externe (40) de sorte que la perméabilité à l'air peut être accrue tout en augmentant la performance de collecte.
