Abstract: The invention relates to a vacuum cleaner filter bag made of a filter material, comprising at least three layers with at least two layers of a non-woven or non-woven fabric layer, and at least one layer of a fibre web layer of fibres and/or filaments, wherein the at least two non-woven layers and the at least one fibre web layer are connected to each other by a thermal bonding connection.

Abstract: A filter bag for a vacuum cleaner includes a tubular bag made of a casing which has at least one nonwoven layer. The casing has a first end region which is sealed at least partially and a second sealed end region situated opposite the first end region. The first end region is folded and forms a base.

Abstract: A filter bag for a vacuum cleaner includes at least three layers, at least two layers which comprise at least one nonwoven fabric layer and one nonwoven fibre layer being connected by a weld, a high bulk resulting due to the small number of welds per surface area.

Abstract: The invention relates to a vacuum cleaner filter bag with an inlet opening, comprising a deflection device which is arranged in the interior of the vacuum cleaner filter bag in the area of the inlet opening and which is implemented such that an air current flowing in through the inlet opening can be deflected by the deflection device, and an air-permeable material layer which is arranged in the interior of the vacuum cleaner filter bag, which is connected to said vacuum cleaner filter bag at least one point, and which includes at least one part that is not connected to the vacuum cleaner filter bag and that includes part of the boundary of the material layer.

Abstract: The invention relates to vacuum cleaner filter bag with a bag wall made of a filter material, wherein the bag wall and/or the interior of the vacuum cleaner filter bag comprise fibres containing a biopolymer and having an antibacterial effect and/or a powder produced from a biopolymer and having an antibacterial effect.

Abstract: The present invention relates to an adsorbing agent for dust-collecting filters, especially for adsorbing odours, the adsorbing agent comprising fibres, flakes and/or granulate as a supporting material onto which a powdery adsorption material is applied superficially.

Abstract: Sprayable low-viscosity rubber damping compounds based on liquid rubbers or elastomers and vulcanization agents, which contain small quantities of structure-reinforcing fiber fillers, are notable for the absence of previously usual solid rubbers and have a very low viscosity in the application state. Acoustic compounds of this kind are sprayable with the aid of fully automatic application systems, and are preferably processed at the basic body stage in vehicle construction.

Abstract: The invention is directed to a nonwoven layer for a filter, in particular, for a vacuum cleaner bag, wherein at least one region of the nonwoven layer, the region having a predetermined thickness and a predetermined area, has an average pore size smaller than 50 ?m and comprises fibers being bonded together such that a movement of the fibers relative to each other in a direction parallel to the surface of the layer is inhibited. The invention is further directed to a filter medium, in particular, for a vacuum cleaner bag, comprising a filter structure wherein a surface or an interface of the filter structure is provided with a filter paper layer having a smaller surface area than the filter structure.

Abstract: Thermosetting binder compositions based on naturally occurring and/or synthetic rubbers containing olefinic double bonds and vulcanizing agents can be formed by extrusion on reinforcing agents in film form or in the form of fiber-containing sheet-like structures to give multi-layered planar shaped articles. Such multi-layered, planar shaped articles are suitable as reinforcing and stiffening agents which are free from the conventional low molecular weight epoxy resins and/or volatile diisocyanates of polyurethane binders. These shaped articles are suitable for stiffening or reinforcing thin-walled planar structural components of metal or plastic, in particular in the vehicle industry.
