Definitions

  • the invention relates to a paper machine clothing, in particular dryer fabric, with or consisting of a textile fabric, for. B. a fabric, knitted fabric, scrim or the like, which has flattened threads in cross section, the longer axis of the cross section of these threads extending parallel to the plane of the paper machine clothing.
  • Paper machine clothing is textile webs of very great length and considerable width, which are used for the formation and guidance as well as the transport of the paper web through the individual parts of the paper machine, essentially the sheet formation section, the press section and the dryer section.
  • fabrics are used as textile fabrics for the material web, the fabric structure of which is specially adapted to the respective requirements in the individual batches of the paper machine.
  • these fabrics are also covered with needled fleece on one or both sides and needled to obtain felt-like surfaces.
  • other flat structures can also be used, for example warp knitted fabrics or scrims.
  • Monofilaments or multifilaments consisting of individual fibers are used for the flat structure of paper machine clothing.
  • Thermoplastic polymers in particular polyamides, polyesters or the like, are practically without exception suitable as materials for this.
  • the monofilaments or the individual fibers of the multifilaments are solid and have a diameter of 0.1 mm and above.
  • the cross section is usually circular.
  • the use of flattened threads has considerable advantages, particularly when used as a dryer fabric.
  • the dryer fabric can be made thinner, which results in better heat transfer from the heating rollers to the paper web.
  • the material density inside the dryer fabric is greater than when using circular threads, which reduces the air permeability.
  • An excessively high air permeability has the consequence that considerable air movements take place through the dryer fabric, which can lead to fluttering of the dryer fabric.
  • the invention is therefore based on the object to design a paper machine clothing of the type mentioned so that it is ensured that the flattened threads are always oriented so that the longer axis of the thread cross section extends parallel to the plane of the paper machine clothing.
  • the invention further relates to a method for producing such a paper machine clothing.
  • the flattened threads consist of monofilaments which are annular in cross section and / or of multifilaments which are formed from individual fibers which are annular in cross section, the monofilaments or individual fibers of the multifilaments which are annular in cross section at least in the areas in which they run essentially parallel to the plane of the paper machine clothing, are plastically deformed to the flattened cross section.
  • Such a paper machine clothing can be produced according to the invention in such a way that hollow monofilaments and / or multifilaments with hollow fibers in cross section are used for the flat structure in cross section and that the flat structure provided therewith or consisting thereof is subjected to such pressure and heat treatment that the Monofilaments or multifilaments are plastically deformed to the flattened cross-section at least in the areas in which they run essentially parallel to the plane of the paper machine clothing.
  • the formation of Fabric initially uses hollow monofilaments and / or multifilaments with hollow individual fibers, so that it does not matter in which orientation they are introduced or integrated into the fabric.
  • the deformation to a flattened cross-section then takes place by a pressure and heat treatment, for example by calendering, in that the finished thread system is passed between one or other pairs of heated rolls.
  • a pressure and heat treatment for example by calendering
  • the hollow monofilaments or the multifilaments with hollow individual fibers are plastically deformed and in this way obtain a flattened cross section. Normal machines can therefore be used for the production of the fabric.
  • hollow fibers as carriers for a treatment liquid in paper machine clothing (EP-A1 0 ⁇ 191 231).
  • This treatment liquid escapes through openings, for example at the end of the fibers, during operation of the paper machine clothing, in particular in order to achieve a cleaning effect.
  • the fibers are parts of spun yarns, multifilaments or needled nonwovens.
  • the monofilaments or fibers of the multifilaments which are ring-shaped in cross-section, are deformed in such a way that their inner sides abut one another, ie. H. are flattened as much as possible in order to achieve the thinnest possible thread system.
  • the paper machine clothing consists of the textile fabric, use as a dryer fabric is particularly suitable.
  • the invention can also be used for all other types of paper machine clothing. If the paper machine clothing is intended as a press felt, there is the possibility of needling the textile fabric with the flattened threads on one or both sides in a manner known per se with a nonwoven fabric, so that the covering is given a felt-like surface on one or both sides.
  • the ring-shaped monofilaments or multifilaments with ring-shaped individual fibers deformed according to the invention can in principle be introduced into the thread system both in the longitudinal and in the transverse direction.
  • Cross-sectionally round threads can then be used for the longitudinal direction.
  • solid flat wires can also be used, since warp threads can be kept twist-free more easily than weft threads in a weaving machine.
  • the paper machine clothing has or consists of a fabric formed as a fabric
  • the fabric has the same weave on both sides, that is to say it is symmetrical in this respect.
  • An advantageous further development of the method according to the invention consists in using hollow monofilaments and / or hollow fibers for the multifilaments as starting material for the flat structure, which have circular cross sections on the outside and inside before they are plastically deformed. The orientation in which they are introduced into the thread system is then irrelevant.
  • hollow monofilaments or hollow individual fibers should also be used for the multifilaments, which have a free cross-sectional area that is between 20 and 80%, preferably 40 to 60% of the total cross-sectional area.
  • a free cross-sectional area that is between 20 and 80%, preferably 40 to 60% of the total cross-sectional area.
  • the dryer fabric (1) shown in the figures is intended for the dryer section of a paper machine. It consists of a fabric (2), which is only shown here as an example in plain weave, with itself in the transverse direction, i.e. H. transverse threads (3, 4, 5) extending transversely to the intended running direction of the drying wire (1) and longitudinal threads (6, 7, 8, 9) extending along the running direction.
  • a fabric (2) which is only shown here as an example in plain weave, with itself in the transverse direction, i.e. H. transverse threads (3, 4, 5) extending transversely to the intended running direction of the drying wire (1) and longitudinal threads (6, 7, 8, 9) extending along the running direction.
  • the transverse threads (3, 4, 5) run relatively straight through the body of the fabric (2) and are designed as solid monofilaments.
  • the longitudinal threads (6, 7, 8, 9) are annular in cross-section during the manufacture of the fabric (2) Hollow monofilaments have been used, as can be seen in particular from Figures (2) and (3).
  • the longitudinal threads (6, 7, 8, 9) initially have a circular cross section on the inside and outside and tie in the cross threads (3, 4, 5).
  • the fabric (2) is subjected to a calendering treatment by passing it between pairs of calendering rollers pressed against one another, which calendering treatment can also be carried out several times. Due to this calendering treatment, the flat sides of the fabric (2) are subjected to a simultaneous pressure and heat treatment.
  • the longitudinal threads (6, 7, 8, 9) designed as hollow monofilaments are flattened, that is to say they assume an almost rectangular cross section, the inside of the longitudinal threads (6, 7, 8, 9) coming to lie on top of one another, such as this is particularly clear from Figures (5) and (6).
  • the thickness of the drying wire (1) is considerably reduced due to the flattening of the longitudinal threads (6, 7, 8, 9).
  • the thickness could be reduced even further by using hollow monofilaments for the transverse threads (3, 4, 5).
