ABSTRACT:
The invention relates to 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 support layer, an adsorptive layer associated to and preferably fixed to the support layer, and optionally a covering layer disposed on that side of the adsorptive layer that is remote from the support layer, wherein the adsorptive filtering material is additionally equipped with a particle- and/or aerosol-filtering layer. The adsorptive filtering material is particularly useful in NBC protective materials of any kind (as in protective apparel for example) and for producing filters.
