Title
(EN) Adsorption filter material with integrated particle- and/or aerosolfiltering function and its use
Abstract
(EN)

The invention provides an adsorptive filtering material endowed with integrated particle and/or aerosol protection and with protective performance with regard to biological and/or chemical noxiants, in particular biological and/or chemical warfare agents, the adsorptive filtering material having a multilayered construction comprising a carrier layer, an adsorptive layer assigned to and preferably fixed to the carrier layer, and optionally a covering layer disposed on that side of the adsorptive layer that is remote from the carrier layer, wherein the adsorptive filtering material is additionally equipped with a particle and/or aerosol filtering layer which is preferably disposed between the adsorptive layer and the covering layer, wherein the particle and/or aerosol filtering layer is embodied as an air pervious textile fabric formed from fibers. The adsorptive filtering material is particularly useful in NBC protective materials of any kind (e.g. NBC protective apparel) and for producing filters.
