Definitions

  • the invention relates to a material web, in particular for paper machine clothing for the press section of a paper machine, as a filter medium or as a press pad for particle board presses, with individual longitudinal threads extending in the running direction and individual transverse threads running transversely thereto.
  • Materials for paper machine clothing, filter media or press pads are manufactured in a variety of forms. In most cases, fabrics are used for the support structure. To achieve a soft surface, voluminous threads are woven in and needled and / or a fleece is needled. In both cases, a covering with a felt-like character is created.
  • EP-PS 59 973 describes a wet felt in which some of the warp threads extending in the longitudinal direction are designed as knitted threads. These threads are elastically compressible and are intended to improve back elasticity and drainage.
  • this wet felt has the disadvantage that the production, in particular of wide fabrics, is time-consuming and therefore costly.
  • machine felts are known, for example for filtering purposes, which consist of voluminous threads running in parallel in the transverse direction and tricot seams which extend parallel to one another in the longitudinal direction (DE-OS 22 13 421).
  • the cross threads go through the mesh of the tricot seams and the material thus formed is then needled for the purpose of felting.
  • the transverse threads essentially form the filter-effective fiber material, while the tricot seams give a certain strength in the longitudinal direction.
  • a machine felt with this structure is not up to the high stresses to which paper machine clothing or press pole strains are exposed and is therefore unsuitable for this purpose.
  • the invention has for its object to give a material web such a structure that it is quick and inexpensive to manufacture on the one hand, and on the other hand opens a great freedom in the design of its properties.
  • the threads running in one direction preferably the longitudinal threads, each consist of a core thread and at least one mesh thread enveloping it.
  • the threads running in one direction have a special structure.
  • Each of these threads forms a unit of soul and shell, the shell being formed by a stitch thread, in particular a warp-knitted thread.
  • the connection of these threads in the transverse direction is produced solely by the cross threads.
  • This structure of a material web allows the quick and inexpensive production on a knitting machine despite the more fabric-like design.
  • the required number of stitch threads can be produced side by side at the same time, and the soul thread can also be inserted at the same time.
  • the soul thread can be optimally adapted to the respective requirements.
  • the soul thread is held together by the stitch thread in such a way that a twisting of the individual yarns of the thread is not necessary. It is sufficient if it is available as a bundle of threads. It is therefore also possible to use or combine yarn materials that cannot be twisted together. Apart from that, very voluminous threads can also be produced. By saving the twisting mill there is an additional cost saving effect.
  • the threads running in the other, preferably in the transverse direction, can also be inserted on the knitting machine in the form of magazine wefts. You then cross the stitches and fix them in the transverse direction.
  • the covering has a pronounced longitudinal structure in the direction of the threads formed from mesh and core threads.
  • this material web is used as paper machine clothing and this structure extends in the longitudinal direction of the paper machine clothing, this has a drainage effect in this direction. Taking into account the latest knowledge of drainage in the press nip between two press rolls, such a drainage effect is extremely desirable and leads to a high drainage of the paper web.
  • the mesh threads expediently consist of a thin monofilament, since they only have to absorb tensile forces to a small extent.
  • the tensile forces are expediently taken over by the tension threads forming the soul threads or existing as part of the soul threads.
  • filler threads made from a wide variety of materials can then be inserted to give the soul threads the desired volume. For example, spun yarns, multifilaments, foam rolls, ribbon structures or even mineral fibers, straw, paper, and electrically conductive materials such as metal fibers or the like can be inserted. If a pull thread is present, the tensile strength of the filler threads is no longer important, so that yarn or thread material can also be used is able to absorb only low tensile forces.
  • the threads running in the other direction are laid as a magazine weft through the stitches of the stitch threads, it is advisable to have them all run on one side of the soul threads, and expediently on the back.
  • the paper contact side is formed only by the threads which are formed from the combination of mesh and core threads. Accordingly, a distinctive longitudinal structure with a good drainage effect is also created on this side.
  • the material web is designed as a needle felt. This can be done by forming the soul threads from voluminous fiber material, which is needled for the purpose of felting.
  • a nonwoven fabric can also be applied to at least one side of the covering and connected to the scrim by needling.
  • a needle felt is particularly suitable as a filter medium, but also as a paper machine covering, in particular as a wet felt for the press section.
  • the material web in a liquid-impermeable plastic band in order to use such a band in wet presses with an extended press nip (cf. EP-A3-0 138 797, DE-A1-32 31 039).
  • the material web is only partially embedded in a liquid-impermeable plastic band and protrudes on one side of the plastic web to form open channels for liquid removal (cf. EP-A2-0 098 502, DE-A1- 32 35 468).
  • the web of material according to the invention can thus be used in a variety of ways.
  • the longitudinal thread (1) shown in Figures (1) and (2) basically consists of a core thread (2) and a warp-knitted stitch thread (3) surrounding the core thread (2).
  • the soul thread (2) forms - as shown in particular in figure (2) - a bundle of threads a total of six individual threads (4, 5, 6, 7, 8, 9).
  • Two (4, 8) of these individual threads are formed as monofilaments from a tensile material, for example polyamide, and essentially absorb the tensile stresses acting on the longitudinal thread (1).
  • the remaining individual threads (5, 6, 7, 9) can consist of a wide variety of materials, since they are relieved of tensile force by the monofilament individual threads (4, 8).
  • the bundle of threads is not twisted together because it is enveloped by the stitch thread (3) and held together.
  • Figure (3) shows a section of a paper machine clothing, which has been produced using the longitudinal threads (1) shown in Figures (1) and (2).
  • the longitudinal threads (1) run parallel in the running direction of the paper machine clothing.
  • the thread density is relatively low, for example three threads / cm. In this way, appropriately directed drainage channels are created between the longitudinal threads (1), which support the drainage.
  • Machine shots run in the transverse direction at regular intervals - designated by (10) for example -. They each cross through the stitches of the stitch threads (3) and lie on the underside of the soul threads (2). Their distance from one another can be varied by the number of stitches per unit length and by the fact that a machine weft (10) is not placed through each stitch.
  • the stitch density can be 6 to 9 stitches / cm and the magazine weft density can be 3 threads / cm. Of course, other values can also be considered.
  • the section shown in Figure (3) shows only one Position of the paper machine clothing. It is possible to lay several such layers on top of each other and to connect them with needle felting. If the seams of the individual layers are staggered, a special seam connection can be dispensed with.
