Definitions

  • the invention relates to a porous dryer fabric for the dryer section of a paper machine with a scrim consisting of at least one layer of longitudinal yarns and at least one layer of transverse yarns crossing the longitudinal yarns, wherein the longitudinal and transverse yarns are interconnected in the region of crossing points.
  • the invention further relates to a process for producing a porous dry sieve for the dryer section of a paper machine in which a scrim of thermoplastic material is produced by arranging at least one layer of longitudinal yarns and at least one layer of transverse yarns intersecting the longitudinal yarns. and transverse threads are interconnected in the region of crossing points.
  • Dryer fabrics are long and wide belts which circulate in the dryer section of a paper machine and with which the paper web is transported through the dryer section. In the dryer section, the paper web and the dryer fabric are passed over heated rollers, whereby further dewatering of the paper web is carried out, in this case, it is better to say drying.
  • the textile thread structures are formed primarily as tissue.
  • so-called scrims are known in which the threads are not integrated with each other, so they are not interwoven or meshed.
  • US Pat. No. 3,097,413 A discloses a papermachine fabric which comprises a scrim consisting of a layer of longitudinal threads which run parallel and at a distance from each other and are not connected to one another. On the situation, a non-woven fabric is applied, which includes the longitudinal threads and is needled with these.
  • a press felt for the press section of a paper machine in which the carrier may be formed as a scrim with at least one layer longitudinal threads and at least one layer of longitudinal threads crossing transverse threads and in which the threads using a water-soluble polymer, for example PVAL, interconnected.
  • the threads may consist of the water-soluble material.
  • the compound can also be prepared by means of a layer of water-soluble material.
  • EP 0 922 806 A2 describes a liquid-impermeable shoe press belt which has a u.a. Also has a carrier designed as a thread carrier within a plastic layer enclosing the carrier. For the initial stabilization of the yarn layer - similar to US 5,888,915 A1 - two-component threads are used, which are fused together by heating. Alternatively, the threads are coated after production of the netting with a chemical material, whereby the threads are connected to each other at the crossing points. Then the scrim is coated with the plastic material.
  • FR 1 571 179 A discloses a papermachine fabric with a scrim consisting of a layer of longitudinal yarns and two layers of transverse yarns enclosing this layer. To connect the longitudinal and the transverse threads, all three layers are initially placed one above the other. Thereafter, continuous adhesive beads are applied on both sides of the longitudinal threads, which have connection between the transverse threads with the longitudinal threads and go over the transverse threads, so that the threads are at the crossing points without adhesive bond to each other.
  • This type of adhesive bond between the layers of the yarn layer of the paper machine clothing has significant disadvantages. So considerable quantities of glue are necessary to produce the adhesive beads along all longitudinal threads, especially since a relatively thick adhesive application is necessary to make the connection. In addition, the strength of the compound in the region of the crossing points is not satisfactory, ie the strength of the yarn layer is not particularly high. In addition, the adhesive beads are completely exposed and thus subject to the risk to go under the moist-warm conditions in the paper machine on the surface in a slightly sticky state. Dirt particles or fibers are then deposited on them, ie the scrim is dirty. The adhering dirt particles can even lead to a deterioration in the quality of the paper web.
  • the invention has the object of providing a dryer fabric in such a way that with him regardless of the type of threads, a high dimensional stability can be achieved.
  • a second object is to provide a method for the production thereof.
  • the first object is achieved in that the longitudinal and transverse threads are formed as flat threads and connected to each other at points of intersection point adhesive.
  • the basic idea of the invention is therefore to connect the surfaces of the longitudinal and transverse threads, which are opposite one another at the points of intersection, over which they normally rest against one another by means of adhesive. Since flat threads are used according to the invention, faces are located at the crossing points, over which the threads are glued together in terms of area.
  • the dryer fabric according to the invention is characterized by high dimensional stability and low cost of production when using Einkomponentenfäden. It is therefore no longer dependent on bicomponent yarns, although the basic idea of the invention also includes such threads, but can use Einkomponentenfäden and still realize a high dimensional stability. Under Einkomponentenfäden are to be understood as such threads, which consist of a homogeneous material, wherein the material may also be a copolymer, provided that only homogeneity is given.
  • the dryer fabric according to the invention has the advantage of high flexibility with regard to the number of layers, the thread density and the choice of material.
  • no elaborate textile machines, such as weaving and knitting machines required for the production which also limits the width of the drying wires to be produced on them.
  • Such a limitation does not exist with thread plies, i. they can be made in practically any width.
  • suture it is possible to dispense with the heat setting necessary for fabrics, if the threads have previously been sufficiently thermally treated.
  • Suitable adhesives are, in particular, hot melt adhesives whose melting temperature is below that of the filaments, diffusion adhesives, contact adhesives and / or reaction adhesives.
  • the longitudinal and transverse threads are additionally positively connected at intersections, wherein the compound in each case from a recess in the one thread and a protruding bordering projections on the crossing thread or at the intersection points aligned recesses and these passing pins, eg Studs or rivets of plastic or metal, may consist.
  • Such a positive connection supports the adhesive bond and gives even more strength.
  • the flat threads are particularly preferred to form with a rectangular cross-section.
  • a suitable width for the longitudinal and transverse threads a range of 2 to 20 mm, preferably 8 to 12 mm, has been found.
  • the thickness should be between 0.3 to 2 mm, preferably 0.6 to 1.2 mm, wherein the transverse threads should have at most the same thickness as the longitudinal threads.
  • passage openings can be provided in the longitudinal and / or transverse threads. Due to their size and number, the permeability can be controlled arbitrarily, whereby the possibility exists to make the permeability across the width of the dryer screen different, eg in the middle higher than in the edge regions or vice versa.
  • the through holes may be formed as round holes or elongated slots.
  • the dryer fabric according to the invention can have any number of layers, wherein in each case one layer with longitudinal threads and one layer with transverse threads alternate, ie in each case are adjacent to one another.
  • An expedient number are two or three layers, wherein in the former case preferably a lower L jossfadengelege is combined with an upper Querfadengelege and in the latter case, a layer with transverse threads is enclosed on both sides of a respective layer of longitudinal threads. In this way, a longitudinal structure is formed at the top and bottom. Of course, there is the possibility to proceed vice versa, so that there is a transverse structure at the top and bottom by the transverse threads present there.
  • the permeability of the dryer fabric can also be adjusted within wide limits, for example, by the width dimensions of the longitudinal and / or transverse threads and / or their thread density.
  • eyelets can also be produced in a simple manner on the end faces of the drying wire by folding over longitudinal threads to form loops, in order to form a plug wire seam with them.
  • This can be done in such a way that end pieces of longitudinal threads of a first layer at the end faces of the Dry sieve with the formation of loops on the side facing away from this layer of the situation with transverse threads and attached to a plurality of these transverse threads, preferably at least five transverse threads, are attached.
  • the attachment can also be made on the longitudinal threads themselves.
  • the fixation can be done in both cases positively, for example by means of bolts or rivets made of plastic or metal.
  • the loop formation should expediently be done only with a part of the longitudinal threads, so that the two end edges mesh with their loops like a comb and thus can form a passageway for a pintle.
  • at least one end piece should be turned over to form a loop and end at least one end piece without forming a loop on the respective outer transverse thread.
  • longitudinal threads should be connected to the ends of the end pieces of longitudinal thread at the position with transverse threads adjacent second layer, i. these longitudinal threads butt against the end pieces, so do not overlap with them, so that it does not come in this area to a compression of longitudinal threads.
  • the material of the threads there are basically no restrictions; it should have high tensile strength, low elongation and a high initial modulus.
  • PET PET, PA in all modifications, PPS, PEK, PEKK, elastic polyester, PBT or PTT or are suitable Combinations thereof.
  • the threads can be armored, eg fiber-reinforced with glass fibers, carbon fibers and / or ceramic fibers, the fibers also being present as short cut fibers.
  • the dryer fabric For use in the dryer section are primarily training in question, in which the dryer fabric consists solely of the scrim, which does not preclude that the scrim is additionally combined with other components, such as a nonwoven fabric.
  • the longitudinal and transverse threads are positively connected to each other at intersection points, for example by interlocking a respective projection on the one thread and a complementary recess on the crossing thread or by inserting a pin such as a bolt or a rivet, in aligned recesses in the threads. This further strengthens the connection at the crossing points.
  • the production of the fabric layer can be made in such a way that initially longitudinal threads are clamped parallel to each other, for example, between two parallel thread trees, and then successively laid on these longitudinal threads individually or in groups transverse threads and glued together at the intersection points longitudinal and transverse threads, wherein
  • a positive connection can be made by the fact that connecting bolts are pierced in aligned at the intersections holes or a projection on one thread is pressed into a complementary recess in the other thread.
  • one or both sides of a fiber layer should be applied to the fabric scrim and attached thereto.
  • the attachment can be done by needling, gluing or melting.
  • transverse threads do not have to be perpendicular to the longitudinal threads, but that with the inventive method and scrim can be produced, in which the transverse threads extend obliquely to the longitudinal threads.
  • two layers of transverse threads may be provided, in which the transverse threads of a layer crossing the longitudinal threads at a different angle than that of the other layer.
  • the papermachine fabric 1 shown in FIGS. 1 to 4 consists of a scrim, the lower layer 2 of which is formed by longitudinal yarns-designated 3 by way of example.
  • the longitudinal threads 3 have - as can be seen in particular from Figure 3 - rectangular cross section and the same distance from each other. For the manufacturing process they are - which is not visible here - wound with their left-hand ends on a thread tree. On the right side is - also not visible here - a second tree provided on the finished papermachine fabric 1 is wound. In this direction (arrow A), the papermachine clothing 1 moves.
  • transverse threads 5 On the pad 2 is a top layer 4 with mutually parallel transverse threads - for example, 5, 6, 7 called - launched.
  • the transverse threads 5 have a wide distance - it corresponds essentially to the distance between the longitudinal threads 3 -, the transverse threads 6 a close distance in order to reduce the permeability of the paper machine clothing 1 and the transverse threads 7 also a close distance, but a substantially smaller width than the transverse threads 5, 6. It is understood that these differences are not present in an actual paper machine clothing, ie it is the same transverse threads with the same distance from each other for use.
  • the illustration is intended merely to symbolize that the method according to the invention enables a very wide variety of types of longitudinal and transverse threads 3, 5, 6, 7 and thread densities.
  • the longitudinal threads 3 are stretched between the two trees and then the transverse threads 5, 6, 7 placed over the longitudinal threads 3.
