The invention relates to an adsorptive filtering material with biological and chemical protective function, in particular with protective function with regard to both chemical and biological poisons and noxiants, such as chemical and bio- logical warfare agents, the adsorptive filtering material having a multilayered construction comprising a first outer supporting layer and a second outer sup- porting layer and an adsorptive layer disposed between the two supporting lay- ers, the adsorptive filtering material further comprising at least one catalytically active component, the first outer supporting layer and/or the second outer sup- porting layer being provided with the catalytically active component. The ad- sorptive filtering material is particularly useful in NBC protective materials (for example NBC protective apparel) and also for production of filters.
La présente invention a pour objet un matériau de filtration adsorbant doté de fonctions de protection chimique et biologique, en particulier de fonctions de protection contre des poisons et des substances nocives biologiques et chimiques, comme des agents de guerre chimique ou biologique. Ledit matériau de filtration adsorbant a une structure à plusieurs couches comprenant une première couche de support extérieure, une seconde couche de support extérieure et une couche adsorbante disposée entre les deux couches de support. Ledit matériau de filtration adsorbant comprend aussi au moins un catalyseur actif, la première couche de support extérieure et/ou la seconde de support extérieure comportant ce catalyseur actif. Le matériau de filtration adsorbant est particulièrement utile pour la fabrication de matériaux de protection NBC (p. ex. des vêtements de protection NBC) ainsi que pour la production de filtres.
