Abstract: In an embodiment, the present invention provides a sound-absorbing textile composite, including: a) at least one open-pore support layer comprising coarse staple fibers having a titer of from 3 dtex to 17 dtex and fine staple fibers having a titer of from 0.3 dtex to 2.9 dtex, as scaffold fibers; and b) a microporous flow layer arranged on the support layer and including microfibers having a fiber diameter of less than 10 ?m. A flow resistance of the sound-absorbing textile composite is from 250 Ns/m3 to 5000 Ns/m3.

Abstract: A microfiber nonwoven composite includes: at least one layer S that contains a first fiber component; and at least one layer M that contains a second fiber component. The second fiber component is forced at least in part into the layer S. Fibers of the first fiber component comprise melt-spun include filaments deposited as a nonwoven fabric, and which are at least partially split and solidified to form elementary filaments having an average titer of less than 1 dtex. Fibers of the second fiber component include melt-blown fibers.

Abstract: A covering layer for a sanitary article includes a base member of non-woven material. The non-woven material is constructed from staple fibres and has a plurality of holes formed therein which have a larger diameter than pores of the non-woven material. The staple fibres have a fibre fineness which is selected from a range from greater than 1 dtex to less than or equal to 5 dtex.

Abstract: A dashboard is constructed of a formed plastic sheet and polyurethane foam laminate having a reinforcement fixture and mat embedded in the foam.

Abstract: Across the gas flow path in a duct such as for air conditioning there is placed a composite filter set comprising a plurality of filter elements and means joining said elements, each of said filter elements comprising a plurality of filter pockets and a frame holding said pockets at their open ends, and said joining means connecting the frames of adjacent filter elements in a manner to form a gas-tight seal therebetween so that flowing gas can advance only by passage through one of said filter pockets.

Abstract: A gas filter element comprising a holding frame and a plurality of self-supporting wedge-shaped filter pockets each having its wide end open and secured to said frame, each element comprising a pair of substantially symmetrical pocket halves secured to one another along the wedge edge and centrally along the opposite wedge end faces, and a plurality of laminar spacing elements with each pocket extending from adjacent the open end toward the wedge edge, each spacing element being secured to the opposite inclined wedge faces, each filter pocket being rendered self-supporting by the securing of the sub-elements to one another and the securing of the spacing elements to the pocket. Advantageously the filter pockets each comprises fusible fibers, the pocket halves being joined to one another by fusion and the spacing elements being secured to the pocket by fusion.
