The invention relates to an adsorption filter material () that provides protection against chemical toxins, chemical weapons and pollutants, with a preferably multi-layer composite construction (). The layer construction () includes at least one planar support layer () with two opposing sides () and an adsorption layer (), provided on the support layer () made from a material which adsorbs chemical toxins, the surface of at least one of the both sides (and/or) of the support layer () being modified by plasma treatment. The surface properties, in particular the surface finish and the surface reactivity can be adjusted and optimised to match the application by means of the plasma treatment.

The present invention relates to a textile sheetlike structure (), in particular for protection against biological and chemical noxiants and poisons, such as biological and chemical warfare agents. The sheetlike structure () having a textile support layer () and a first sheetlike piece () of activated carbon fibers which is laminated onto the support layer (), wherein the sheetlike structure () further comprises a second sheetlike piece () of activated carbon fibers which is laminated onto the support layer () such that edges of the two sheetlike pieces () touch and/or overlap and wherein the two sheetlike pieces () are joined together by the support layer (). This provides a seamless joining together of two or more sheetlike pieces to form a continuous sheetlike structure of activated carbon fibers to provide an improved material for use in the production of protective articles.
