Abstract
Ce filtre à air triboélectrique comprend un mélange de fibres (1) de polypropylène avec des fibres (2) de polymétaphénylène isophtalamide. De préférence, le rapport en poids des fibres (2) aux fibres (1) est compris entre 5:95 et 50:50, et préférentiellement encore entre 10:90 et 30:70. La masse surfacique de ce filtre qui présente avantageusement sous la forme d'un non-tissé, est de préférence comprise entre 15 et 500 g/m2. Ce filtre possède une très grande efficacité et est utilisable dans tous les appareils où une filtration de l'air est requise.
