Title
(DE) Adsorptionsfiltermaterial mit integrierter Partikel- und/oder Aerosolfilterfunktion sowie seine Verwendung
(EN) Adsorption filter material for producing protective materials, particularly protective clothing and covering for civilian or military sector, filter material and filters for removing pollutant, has integrated particle and aerosol protection
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/m<SUPesonders 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 adsorption filter material (1) has integrated particle and aerosol protection. A multilayer construction (2) is provided, which comprises a carrier layer (3), and an adsorption layer (4) fastened to the carrier layer. A covering layer (5) is arranged on the carrier layer opposite to the adsorption layer, and a particle or aerosol filter layer (6) is provided to the multilayer construction. The particle or aerosol filter layer is formed as an air permeable textile flat structure made of fibers.
