Example Embodiment

[0037] figure 1 The warp-knitted structure 1 to which the intermediate layer 2 is connected is shown. The warp-knitted structure 1 is composed of a sewing thread 3 and a reinforcing thread 4, which extend parallel to each other along their length, wherein the bending rigidity of the reinforcing thread 4 is greater than that of the sewing thread 3. These sewing threads 3 form a mesh, and in order to form the warp-knitted structure 1, reinforcement threads 4 are knitted into the mesh. At present, the sewing threads 3 form mesh rows 5 arranged parallel to each other and extending substantially perpendicular to the reinforcing threads 4, and the reinforcing threads 4 are woven into these meshes.

[0038] According to the present invention, an intermediate layer 2 is provided on the warp-knitted structure 1, and the intermediate layer is connected to a reinforcing thread 4 by a sewing thread 3.

[0039] The intermediate layer 2 is currently composed of a spunbond nonwoven fabric, which...

Abstract

The invention relates to a clothing especially a press felt for a paper, cardboard or tissue machine with a nonwoven structure comprising staple fibers and which provides the paper and running side of the clothing and with a base structure which is embedded into the nonwoven structure, whereby the base structure comprises a warp knit structure which has sewing threads and reinforcing threads extending lengthways parallel to each other and which have a greater flexural strength than the sewing threads, whereby the sewing threads form loops into which the reinforcing threads are tied thereby forming the warp knit structure. The invention is characterized in that an intermediate layer is arranged at the warp knit structure which is connected with the reinforcing threads by way of the sewing threads.

Description

technical field [0001] The invention relates to a clothing for a paper machine, cardboard or tissue paper machine, which has a nonwoven structure of short fibers and is embedded in the nonwoven structure, comprising a paper side and a running side provided with the clothing in the basic structure. Background technique [0002] Clothings of the stated type, in particular press felts, often comprise, in addition to the known components such as the nonwoven structure and the base structure providing dimensional stability, further functional layers by means of which, for example, the rewetting properties of the clothing or Shock-absorbing properties. [0003] Manufacturing these complex structures requires a large number of individual processes. Contents of the invention [0004] The technical problem to be solved by the present invention is to improve a kind of clothing of the type mentioned in the opening part, so that this clothing can be produced simply and cheaply, and ...
