An adsorber material for collecting, concentrating and/or recovering gaseous and/or particle-shaped trace substances from an air or gas flow, in which the adsorber material is composed of fibrous elements made of natural and/or synthetic, organic, textile fibers which are worked into a nonwoven web

An adsorber material for collecting, concentrating and/or recovering gaseous and/or particle-shaped trace substances from an air or gas flow, in which the adsorber material is composed of fibrous elements made of natural and/or synthetic, organic, textile fibers which are worked into a nonwoven web having a planar geometry, the nonwoven web having a thickness of between 100 m2. Preferably the fibers have a fiber size between 1 and 10 dtex and are composed of cellulose and/or polyester, and if desired, the fibers may be provided with a binding agent and/or a moisture resistance agent. In preferred embodiments the nonwoven adsorber web is a fiber mixture of 80 parts polyester fibers, 20 parts viscose rayon staple fibers, and 20 parts polyvinyl alcohol fibers or a fiber mixture of 50 parts viscose rayon staple fibers and 50 parts linters, which are provided with an epichlorohydrin resin binder. The adsorber webs can be used to detect gaseous or particulate trace contaminants in air or another gas stream.
