PCT No. PCT/EP93/01759 Sec. 371 Date Jan. 6, 1995 Sec. 102(e) Date Jan. 6, 1995 PCT Filed Jul. 7, 1993 PCT Pub. No. WO94/01198 PCT Pub. Date Jan. 20, 1994In order to improve the handling and filtering characteristics of a multilayered, textile, gas-permeable filter material against toxic chemical substances and, in particular, filter and protective materials for the production of sheet-like filters and protective suits for the civil and military fields, it is suggested that this filter material have a first layer as textile support layer which is bonded to a second layer present in the form of an areal adhesive layer. In addition, the filter material has a third layer applied to the second layer and areally bonded thereto, this third layer comprising a textile sheet-like layer containing activated carbon fibers.
