The felt material with barrier function, comprises a first felt layer (2a), a second felt layer (2b) and a fluid absorbing layer in partial area, where the fluid absorbing layer is an absorber-containing layer. The first felt layer, the absorber-containing layer and/or the second felt layer are needled to each other. The absorber (4) is limited in its three-dimensional extension through the felt layer and/or barrier element. The felt material is partially air-permeable in dry, opened condition and occludes itself in contact with fluid, water or steam through the expansion of the absorber. The felt material with barrier function, comprises a first felt layer (2a), a second felt layer (2b) and a fluid absorbing layer in partial area, where the fluid absorbing layer is an absorber-containing layer. The first felt layer, the absorber-containing layer and/or the second felt layer are needled to each other. The absorber (4) is limited in its three-dimensional extension through the felt layer and/or barrier element. The felt material is partially air-permeable in dry, opened condition and occludes itself in contact with fluid, water or steam through the expansion of the absorber. The fluid transport is limited or stopped through the felt material through the absorber. The absorber layer is fleece with absorber polymer, an absorber polymer, an absorber, an absorber with carrier material (5), absorber granulates or absorber fiber. The absorber is a super absorber polymer or a swellable polymer. The felt material consists of three layers in part areas, where the first layer is felt layer with a layer arranged on the felt layer in the part area. The second felt layer is arranged on the first felt layer and the third layer is partially felted or needled to each other. The absorber is partially limited in its three-dimensional extension partially through the connection of fibers between the felt layers. The felt layer consists of synthetic, semi-synthetic, animal, mineral, metal
