摘要： A clothing for a machine for producing a fibrous web, especially a paper, cardboard, tissue or cellulose pulp web. The clothing has a basic structure with a top side and a running side as well as a nonwoven support at least on one side. The nonwoven support has a functional zone, which extends over more than 50 μm in the thickness direction of the clothing and which includes a first portion and a second portion of nonwoven fibers. The nonwoven fibers of the first portion are formed of, or include, a polyurethane, especially a thermoplastic polyurethane, while the nonwoven fibers of the second portion are a polymer material not including a polyurethane. The first portion makes up between 10 wt. % and 60 wt. %, of the functional zone. There is also described a method for production and a suitable nonwoven fabric.

摘要： A basic structure of a clothing for a machine for producing or processing a fibrous web, in particular a paper, cardboard or tissue web. The basic structure has at least a first flat fabric of fabric type A and a second flat fabric of fabric type B, and, furthermore, two loop elements. The loop elements are formed in each case from a flat fabric piece which has a first portion of fabric type A and a second portion of fabric type B. The first portion is laid down on the second portion in such a way that the folding point is formed at a spacing of less than 5 cm, in particular less than 1 cm, from the changeover position between the fabric type A and the fabric type B. The first and the second flat fabric are arranged above one another, and the two loop elements are arranged in each case at a face-side, front end.

摘要： A fabric, in particular a felt, for use in a machine for producing a tissue web, has a base structure, which has a textile structure with MD threads, and at least one layer of nonwoven fibers. The MD threads predominantly or as a whole have a diameter ranging between 0.25 mm and 0.45 mm, in particular between 0.3 mm and 0.35 mm, and the thread density of the MD threads is more than 37%, in particular between 37% and 45%. There is also described a machine and a method for producing a tissue web using such a fabric.

摘要： A seamed felt for use in a machine for producing a tissue web has a single-layer or multilayer base structure and at least one layer of non-woven fibers. The base structure has a textile structure with MD threads which form seam loops at the two front edges of the base structure. The fabric can be made endless by connecting its front edges by way of a seam. The seam can be formed by interlocking the seam loops of the two front edges and introducing a push-in element. The MD threads wholly or predominantly have a diameter between 0.25 mm and 0.45 mm, in particular between 0.3 mm and 0.35 mm, and the thread density of the MD threads is more than 37%, in particular between 37% and 45%. There is also described a corresponding machine and a method for producing a tissue web.

摘要： A fabric clothing, in particular a press felt, for use in a machine for producing a fibrous web, contains a woven fabric strip having interwoven longitudinal threads and cross threads, as well as having a first and a second longitudinal end. The two longitudinal ends of the woven fabric strip are connected to one another in a connection zone. Provision is made that the two longitudinal ends are welded to one another by a transmission welding, in particular by a laser transmission welding.

摘要： A clothing, in particular a seam felt for a machine producing a fibrous material web, in particular a paper, paperboard, tissue or pulp web, includes a base structure including or formed of a two-layer laminate structure formed of one or more flat-woven fabrics. The laminate structure has MD threads forming seam loops at two end sides of the base structure, and the two layers of the laminate structure are connected to one another by the seam loops. The clothing is made endless by connecting the end sides by a seam. The seam is made by interengaging the seam loops of both end sides and introducing an insertion element. The diameter of the seam loops LD and the diameter of the associated MD threads MDYD have a ratio LD/MDYD of between 2.5 and 4, in particular between 2.7 and 3.6.
