Abstract

L'invention concerne un média de filtration amélioré pour masque facial, qui comporte une bande de conformation polymère/pâte réalisée par fusion-soufflage constituée d'une matrice de fibres de polypropylène obtenues par fusion-soufflage et de fibres de pâte disposées tout au long. Les fibres de polypropylène obtenues par fusion-soufflage peuvent être constituées à partir d'un mélange polymère ayant un additif électret destiné à améliorer les caractéristiques de filtrage électret des fibres polymères. L'invention concerne également tous les styles ou conception de masques faciaux utilisant le média de filtration amélioré.
