(FR) MÉDIA FILTRANT, ÉLÉMENT FILTRANT ET LEUR UTILISATION, ET SYSTÈME FILTRANT

Abstract:
(EN) A filter medium (10) for filtering a fluid, in particular for use in an interior air filter (32), comprises a spun-bonded fabric material formed at least in part of multi-component segmented pie fibers (1) having at least a first synthetic component (2) and a second synthetic component (3). The multi-component fibers (1) are largely non-split, and in order to manufacture same, segmented pie filaments are spun in a spun-bonding process (S4) to form a spun-bonded fabric material (10). The segmented pie filaments then form the multi-component fibers (4), the first synthetic component (2) and/or the second synthetic component (3) being made in particular of a polypropylene.
(FR) L'invention concerne un média filtrant (10) servant à filtrer un fluide, en particulier destiné à être utilisé dans un filtre à air d'habitacle (32), et comprenant un matériau non-tissé voie fondue qui est formé au moins en partie de fibres multicomposantes segmentées « pie wedge » (1) ayant au moins une première composante plastique (2) et une deuxième composante plastique (3). Les fibres multicomposantes (1) sont dans une très large mesure non séparées et, pour la fabrication, des filaments segmentés « pie wedge » sont filés en un matériau non-tissé (10) selon un procédé par voie fondue (S4). Les filaments segmentés forment ensuite les fibres multicomposantes (4), la première composante plastique (2) et/ou la deuxième composante plastique (3) étant composées en particulier d'un polypropylène.
(DE) Ein Filtermedium (10) zum Filtern eines Fluides, insbesondere zur Verwendung in einem Innenraumluftfilter (32), umfasst ein Spinnvliesmaterial, welches zumindest teilweise aus kreissegmentierten Mehrkomponentenfasern (1) mit mindestens einer ersten Kunststoffkomponente (2) und einer zweiten Kunststoffkomponente (3) gebildet ist. Die Mehrkomponentenfasern (1) sind weitestgehend ungesplittet und zur Herstellung werden kreissegmentierte Filamente in einem Spinnvliesverfahren (S4) zu einem Spinnvliesmaterial (10) versponnen. Die kreissegmentierten Filamente bilden dann die Mehrkomponentenfasern (4), wobei die erste Kunststoffkomponente (2) und/oder die zweite Kunststoffkomponente (3) insbsondere aus einem Polypropylen bestehen.
