Abstract
Described is an adsorption filter material, in particular for NBC protective apparel, preferably for wearing next to the skin, in particular as an undergarment (underwear), wherein the adsorption filter material has a multilayered construction, wherein the multilayered construction comprises a first textile sheet material, a second textile sheet material and an adsorption layer disposed between the first and the second textile sheet materials, wherein the adsorption layer includes discrete, in particular grain-shaped, preferably sphere-shaped, sorbent particles, preferably based on activated carbon, adsorbing chemical and/or biological poison and noxiant materials, in particular warfare agents. The adsorption filter material is characterized in that the first textile sheet material and the second textile sheet material are each adapted to be elastic in at least one direction, preferably in both directions, and/or in that the first textile sheet material and the second textile sheet material have at least essentially the same elasticity properties. The adsorption material combines a high wearing comfort with excellent protection with regard to chemical poisons.
