Benefits of technology
[0010]The present invention further has for its object to provide a protective material that combines a high water vapor transmission rate and hence a high wearing comfort with an effective protective performance with regard to chemical and/or biological poisons and noxiants, such as warfare agents.
[0011]The present invention yet further
Problems solved by technology
There are a series of materials which are taken up by the skin and lead to serious physical harm (noxae).
The disadvantage here is that these suits very quickly lead to a heat build-up, since they are air and water vapor impervious.
Other disadvantages here include the nonexistent breathability and also the nonexistent exchange of air.
Under extreme conditions, more particularly when a drop of a thickened poisonous or warfare agent lands on the protective suit material from a comparatively great height and strikes through to the activated carbon, however, the layer of activated carbon can be locally overtaxed.
In addition, protective suits of this kind often only offer an inadequate protective performance in respect of biological noxiants.
The disadvantage with this protective material or filtering system is the fact that impregnation with the catalyst destroys a portion of the adsorption capacity needed for adsorbing and thus disarming chemical noxiants.
The impregnating operation thus has an adverse impact on the performance capability of the activated carbon used.
Furthermore, impregnating the activated-carbon material is relatively costly and often compromises the manufacturing operation for the activated carbon, more particularly the activating step.
Moreover, impregnation with the catalyst does not always provide the d

Abstract
The object of the invention is a functional protective material, especially with the function of protecting against chemical and/or biological poisons and/or noxious materials, such as combat agents, wherein the functional protective material comprises a multilayer construction. The multilayer construction has a two-dimensional backing material, especially a textile backing material and a membrane, which is assigned to the backing material and, in particular, is connected therewith. The membrane is provided with a reactive finish, especially with a component having catalytic activity preferably with respect to chemical and/or biological poisons and/or noxious matter. The adsorption filter material is suitable particularly for use in ABC protection objects (such as ABC protective clothing).
