Abstract
(DE)
Die Erfindung betrifft ein Adsorptionsfiltermaterial, welches mit einem integrierten Partikel- und/oder Aerosolschutz und mit einer Schutzfunktion gegenüber biologischen und/oder chemischen Schadstoffen, insbesondere biologischen und/oder chemischen Kampfstoffen, ausgerüstet ist, wobei das Adsorptionsfiltermaterial einen mehrschichtigen Aufbau mit einer Trägerschicht, einer der Trägerschicht zugeordneten, vorzugsweise an der Trägerschicht fixierten Adsorptionsschicht und gegebenenfalls einer auf der der Trägerschicht abgewandten Seite der Adsorptionsschicht angeordneten Abdeckschicht aufweist, wobei das Adsorptionsfiltermaterial zusätzlich mit einer vorzugsweise zwischen Adsorptionsschicht und Abdeckschicht angeordneten Partikel- und/oder Aerosolfilterschicht ausgerüstet ist, wobei die Partikel- und/oder Aerosolfilterschicht als ein aus Fasern mit Faserdurchmessern im Bereich von 10 nm bis 5 μm, bevorzugt 100 nm bis 1,1 μm, gebildetes luftdurchlässiges textiles Flächengebilde, vorzugsweise mit einem Flächengewicht von 1 bis 75 g/m2, insbesondere 2 bis 50 g/m2, besonders bevorzugt 5 bis 15 g/m2, ausgebildet ist. Das Adsorptionsfiltermaterial eignet sich insbesondere zur Verwendung in ABC-Schutzmaterialien aller Art (wie z. B. ABC-Schutzbekleidung) sowie zur Herstellung von Filtern.

(EN)
The invention relates to an adsorption filter material with integrated particle and/or aerosol protection and with protective performance against biological and/or chemical noxious substances, in particular biological and/or chemical warfare agents, the adsorption filter material including a multilayered construction comprising a carrier layer, an adsorption layer facing the carrier layer and preferably fixed to the carrier layer, and optionally a covering layer disposed on that side of the adsorption layer which is remote from the carrier layer, the adsorption filter material additionally including a particle- and/or aerosol-filtering layer preferably disposed between the adsorption layer and the covering layer, the particle- and/or aerosol-filtering layer being constructed as an air-permeable textile fabric formed from fibres having fibre diameters in the range from 10 nm to 5 &mgr;m, preferably 100 nm to 1.1 &mgr;m and preferably having a basis weight of 1 to 75 g/m2, in particular 2 to 50 g/m2, more preferably 5 to 15 g/m2. The adsorption filter material is particularly useful in NBC protective materials of any kind (such as NBC protective apparel for example) and in the manufacture of filters.

L'invention concerne un matériau de filtration par adsorption auquel sont intégrées une protection contre les particules et/ou les aérosols et une fonction de protection vis-à-vis de substances biologiques et/ou chimiques nocives, en particulier des substances biologiques et/ou chimiques de combat, le matériau de filtration par adsorption présentant une structure multicouche qui comprend une couche de support, une couche d'adsorption associée à la couche de support et de préférence fixée sur la couche de support et éventuellement une couche de recouvrement disposée sur le côté de la couche d'adsorption non tourné vers la couche de support, le matériau de filtration par adsorption étant de plus doté d'une couche de filtration des particules et/ou des aérosols, disposée de préférence entre la couche d'adsorption et la couche de recouvrement, et la couche de filtration des particules et/ou des aérosols étant configurée comme tissu textile plat perméable à l'air formé de fibres d'un diamètre compris dans la plage de 10 nm à 5 µm et de préférence de 100 nm à 1,1 µm, et qui présente de préférence un poids par unité de surface de 1 à 75 g/m2, en particulier de 2 à 50 g/m2 et de façon particulièrement préférable de 5 à 15 g/m2. Le matériau de filtration par adsorption convient en particulier pour être utilisé dans les matériaux de protection ABC de tout type (par exemple les vêtements de protection ABC) ainsi que pour la fabrication de filtres.
