Abstract

The present invention relates to a textile sheetlike structure (1), in particular for protection against biological and chemical noxiants and poisons, such as biological and chemical warfare agents. The sheetlike structure (1) having a textile support layer (2) and a first sheetlike piece (3) of activated carbon fibers which is laminated onto the support layer (2), wherein the sheetlike structure (1) further comprises a second sheetlike piece (4) of activated carbon fibers which is laminated onto the support layer (2) such that edges of the two sheetlike pieces (3, 4) touch and/or overlap and wherein the two sheetlike pieces (3, 4) are joined together by the support layer (2). 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.
