Abstract
The invention relates to an adsorption filter material with a multilayer construction, particularly with a permeable adsorptive barrier layer composite, preferably for ABC protective clothing, wherein the adsorption filter material has at least a first barrier layer having a plurality of openings and at least a second barrier layer having a plurality of openings, as well as an adsorption layer disposed between the first and second barrier layers, wherein the first and second barrier layers are disposed in such a manner, that the openings and the openings do not overlap and/or do not coincide. The adsorption filter material is very comfortable and, at the same time, offers excellent protection against chemical poisons.
Claims18
An adsorptive filtering material of multilayered construction, the adsorptive filtering material comprising a permeable adsorptive blocking layer composite,
- wherein the adsorptive filtering material includes
- (i) at least one first blocking layer that includes a multiplicity of perforations;
- (ii) at least one second blocking layer that includes a multiplicity of perforations;
- and
- (iii) an adsorptive layer arranged between the first blocking layer and the second blocking layer;
- wherein the first blocking layer and the second blocking layer, independently of each other, are produced from a plastics material or polymer material and configured as foil, film or membrane;
- and
- wherein the first blocking layer and the second blocking layer are arranged such that the perforations of the first blocking layer and the perforations of the second blocking layer are non-overlapping and/or non-congruent.
