Abstract:
1. An adsorbing material for producing protective materials, said adsorbing material comprising: a sheet-like carrier material; an at least essentially air-impervious, water-vapor-pervious barrier layer; wherein the barrier layer forms a continuous, uninterrupted layer on the carrier material, the thickness of the barrier layer being in the range from 1 to 500 μm, and wherein the barrier layer is permeation resistant to chemical poisons and warfare agents in that it prevents or at least retards the passage of chemical poisons and warfare agents; and an adsorbing layer based on activated carbon, wherein the barrier layer is atop the carrier material and also serves as a bonding layer for the adsorbing layer disposed on that side of the barrier layer which is remote from the carrier material and wherein the barrier layer is formed as a multilayered laminate or as a multilayered composite comprising at least three interconnected layers or plies, and wherein the multilayered laminate or the multilayered composite comprises a core layer and two outer layers connected to the core layer, the corner layer being formed on the basis of a cellulose- or polyurethane-based polymer and the two outer layers connected to the core layer being formed on the basis of a polyurethane.
