ABSTRACT:
The invention relates to an adsorbing material (1) with a protective function against chemical toxins, especially chemical warfare agents, the adsorbing material (1) comprising a multilayered layer construction (2), the layer construction (2) comprising at least one in particular sheetlike carrier layer (3) and, associated to the carrier layer (3), a barrier layer (4) which prevents or at least retards the passage of chemical poisons, the barrier layer (4) comprising on the one hand at least one adsorbing layer (5) based on an adsorbent for chemical poisons and especially on activated carbon, and, on the other hand, at least one at least essentially water and air impervious but water vapor pervious membrane (6) which retards the passage of chemical poisons or is at least essentially impervious to chemical poisons. The adsorbing material (1) has a high wear comfort, in particular good breathability, while at the same time having excellent protection against chemical poisons.
