Title (EN) TEXTILE FILTER FOR GAS FLOW,COMPRISING ORGANIC FIBERS GRAFTED WITH ACTIVE MONOMERS
(FR) FILTRE TEXTILE POUR FLUX GAZEUX, COMPRENANT DES FIBRES ORGANIQUES GREFFEES AVEC DES MONOMERES ACTIFS
Abstract: front page image
(EN)The filter comprises a filtering substrate including organic, natural or synthetic fibers, of which at least part are grafted with at least one organic monomer capable of retaining physically and chemically some of the particles to be eliminated which are conveyed by the gas stream. The fibers are grafted by irradiation at room temperature and woven or needled, the fibers comprising advantageously multi grafted fibers or a set of fibers grafted differently. A grafting with fluorinated monomers further improves the qualities of the mechanical filtering of the filter.
(FR)Le filtre comprend un substrat filtrant comportant des fibres organiques, naturelles ou synthetiques, dont au moins une partie est greffee avec au moins un monomere organique capable de retenir physiquement et chimiquement certaines des particules a eliminer vehiculees par le flux gazeux. Les fibres sont avantageusement greffees par irradiation a la temperature ambiante puis tissees ou aiguilletees, les fibres comprenant avantageusement des fibres multigreffees ou un jeu de fibres differemment greffees. Un greffage avec des monomeres fluores ameliore en outre les qualites de filtrage mecanique du filtre.
