Abstract: The invention provides a nonwoven laminate, comprising in order (A) to (E): a spunbond nonwoven layer (A) comprising fibres, which comprise polyethylene terephthalate (PET) and copolyester; an optional spunbond nonwoven layer (B) comprising fibres, which comprise polyethylene terephthalate (PET) and copolyester, the nonwoven layer (B) having a higher copolyester content than nonwoven layer (A); a needled staple fibre nonwoven layer (C), comprising: monocomponent polyethylene terephthalate (PET) staple fibres (c1), and multicomponent staple fibres (c2), which comprise at least a polyethylene terephthalate (PET) component and a copolyester component; an optional spunbond nonwoven layer (D) comprising fibres, which comprise polyethylene terephthalate (PET) and copolyester, the nonwoven layer (D) having a higher copolyester content than nonwoven layer (E); a spunbond nonwoven layer (E) comprising fibres, which comprise polyethylene terephthalate (PET) and copolyester; wherein all layers are melt-bonded to each ot

Abstract: A filter arrangement for a vehicle includes a flat filter element. The filter element has a filter medium and is integrated into an interior component of the vehicle. The filter element forms a surface facing an interior of the vehicle. In an embodiment, air flows through the filter element, and the air exits through the filter element into the interior of the vehicle.

Abstract: An electrically conductive sheet material having a base body with fibers, at least part of the fibers having carbon fibers, optionally having channels extending through the base body, capable of providing an electrically conductive and flexible sheet material which has a low electrical resistance and which can be produced on a large scale in the most simple, cost-effective and reproducible manner possible.

Abstract: The present invention relates to textile sheetlike constructions having an enhanced watertightness and also to a process for producing them. It was found that, surprisingly, the watertightness of porous textile sheetlike constructions is enhanced when a coating of hydrophobic particles having an average particle size in the range from 0.02 to 100 ?m is applied to the surfaces of the fibers. The textile sheetlike constructions can be used for example as textile building materials or for producing tents, umbrellas or the like.

Abstract: Functionalized nonwovens having a negative zeta potential in the pH range from 1 to 13 include fibers having a surface layer or surface regions applied by plasma treatment having anionic groups covalently bonded to the fiber surface and/or having precursors convertible into anionic groups and/or having polyether groups and/or polyol groups. The nonwovens may be used as filter materials or separation materials.

Abstract: A plasma-treated planar textile structure containing synthetic fibers and a method for manufacturing the structure, wherein the structure has a high initial wettability, expressed by a height of rise of at least 80 mm after immersion for 30 minutes in an aqueous potassium hydroxide solution, and, upon storage for three months in air at 25° C., has a high initial wettability, expressed by a height of rise of at least 75 mm after immersion for 30 minutes in an aqueous potassium hydroxide solution. The plasma-treated planar textile structures preferably have a high hydrophilic stability when stored in alkaline media. The plasma-treated planar textile structures can be used, in particular, as separators for electrochemical energy storage devices.

Abstract: The invention relates to a method for graphitising a carbonised fabric. According to said method, the carbonised fabric is heated to temperatures of between 1,200° C. and 3,200° C. in lines or columns, by means of a laser beam, with admission of air.

Abstract: The invention relates to a method for the carbonization of an at least inherently stable two-dimensional textile structure, according to which preoxidized fibers or a mixture of preoxidized and non-oxidized fibers is combined to give a two-dimensional structure and is solidified. Said two-dimensional structure is heated up to temperatures ranging from 600° C. to 900° C. line by line or column by column by means of a laser beam and while supplying air, and the temperature increases as the process output increases.
