Definitions

  • the invention relates to felts for use in papermaking machines, and has to do more particularly with felts for removing water from a paper sheet while the sheet is supported on and carried by the felt.
  • the press felts are woven so as to have relatively large open areas or voids which will enhance their water conveying capabilities so that the water may be removed from the felt upon passage over a suction box.
  • the press felt normally has a conveyer belt-like shape and during the various operations previously mentioned, a large amount of water is built up in the press felt which is removed by suction or various other drainage devices, usually after the paper web and press felt are no longer in direct contact.
  • the ideal papermaking felt should have at least the following properties. First, it should have a surface that is fine enough to produce a smooth finish and minimize marking of the sheet of paper being produced. Second, it should be open enough to allow water to drain through it without significant impedance. Third, it should be resilient enough to quickly recover from repeated high nip pressures over a long period of time. Fourth, it should be tough and strong enough to provide good stability, wear resistance and felt life.
  • an object of the present invention to provide a fabric for use in papermaking machine having improved vibration absorption capacity.
  • a papermakers felt having a dual layer base fabric woven in a special weave pattern which results in a base fabric having energy absorbing characteristics.
  • the yarns are woven in a pattern in which the number of machine direction yarns on the top side of the fabric is twice the number of the machine direction yarns on the bottom side of the fabric.
  • the yarns may be spun yarns, multi-filaments, monofilaments, core-wrapped yarns or any kind of twists.
  • the bottom fabric is attached to a top fabric by needling.
  • a preferred top fabric is a single layer fabric with long floatings and fine yarn components.
  • a felt having the absorber base fabric of the present invention having the special weave pattern shows significantly higher vibration absorption capacity compared to usual felts. High elasticity and resilience assure better runnability, fewer maintenance stops and improved paper quality. The concept reduces flow resistance giving better dewatering performance.
  • the top fabric together with the absorber fabric the requirements of the felt are adapted to paper quality (weight, surface) and press conditions (speed, pressure, runnability).
  • the base fabric may be used as a forming fabric in a papermaking machine.
  • the yarns of the base fabric are treated or extruded with elastic resins or polymeric materials having superior dampening characteristics.
  • Materials include monofilaments or multi/monofilaments twists in machine direction, which can be treated or extruded with elastic resins (polyurethane, latex, polyacrylic, etc).
  • An example of a suitable fiber is thermoplastic polyester elastomer, or TPE.
  • the specially treated yarns are provided in the machine direction to provide a papermaking fabric having improved vibration dampening ability.
  • the felt is comprised of a dual layer base fabric 28 woven in a special pattern to improve its dampening characteristics, in combination with a top fabric 27, as shown in FIG. 3.
  • the base fabric 28 can function either as a forming fabric for use in a papermaking machine, or when it is combined with a top fabric 27, as a papermaker's felt.
  • the dual layer base fabric consists of a fabric having sets of either machine direction yarns or cross machine direction yarns in more than one plane. Dual layer fabrics are manufactured in two basic ways to form an endless belt. First, they can be woven by a flat weaving process with their ends joined by any one of a number of well known methods to form the endless belt.
  • the warp yarns extend in the machine direction and the filling yarns extend in the cross machine direction.
  • the warp yarns extend in the cross machine direction and the filling yarns extend in the machine direction.
  • machine direction and “cross machine direction” refer respectively to a direction corresponding to the direction of travel of the papermakers fabric on the papermaking machine and a direction transverse this direction of travel.
  • FIG. 1 This figure is a weave diagram illustrating the weave pattern of the fabric of the present invention on six harnesses.
  • the six horizontal rows of the diagram, numbered 1 through 6, represent six cross-machine direction yarns.
  • the vertical columns of the diagram numbered 7 through 24 represent 18 machine direction yarns.
  • the "X" marks on the diagram represent those points at which the machine direction yarns are woven under the cross-machine direction yarn indicated at that point.
  • the "O” marks in the diagram illustrate those points at which the machine direction yarns are woven above the cross-machine direction yarn indicated in that point.
  • the pattern repeats on every six cross-machine direction yarns and on every 18 machine direction yarns.
  • one weave repeat is designated as 1 through 6 for the cross-machine direction yarns and 7 through 24 for the machine direction yarns.
  • FIG. 2 is a schematic cross-sectional representation of the path of the cross-machine direction yarns of the base fabric of the present invention. It illustrates the six cross-machine direction yarns in one weave repeat and shows their relative position with respect to the same machine direction yarns.
  • Numbers 7, 8, 10, 11, 13, 14, 16, 17, 19, 20, 22 and 23 refer to the machine direction yarns on the top side 25 of the fabric 28.
  • Numbers 9, 12, 15, 18, 21 and 24 refer to the machine direction yarns on the bottom side 26 of the fabric 28. It is clear that the fabric 28 has twice as many machine direction yarns on the top side 25 as it has on the bottom side 26.
  • FIG. 3 shows a cross sectional view of the fabric 28 together with a top fabric 27.
  • the top fabric 27 may be any fabric needled to the base fabric 28 in the conventional manner.
  • a preferred top fabric is a single layer fabric with long floatings and fine yarn components (i.e., 0.2 mm x 2 ply or 0.15 mm x 3 ply, etc.).
  • an increase in hysteresis of greater than 25 percent (25%) has resulted.
  • the vibration dampening characteristics are tested by measuring elasticity modulus and loading hysteresis on a load tester. The dampening characteristics depend on the flexibility of the base fabric 28 or the base fabric 28 in combination with the top fabric 27.
  • the second embodiment includes the use of yarns in the machine direction that are treated or extruded with elastic resins or polymers.
  • Preferred materials include monofilaments or multi/monofilament twists in machine direction which can be treated or extruded with elastic resins such as polyurethane, latex, polyacrylic, etc. The use of such materials provides a further improvement in hysteresis values.
  • thermoplastic polyester elastomer or TPE
  • the yarn may be 0.020 inch diameter "Riteflex” made by Hoechest Celanese.
  • Thermoplastic polyester elastomer should be available from the supplier in monofilament diameters between 0.004 inches and 0.060 inches. This material could be used in multifilament form as well. There are other polymers available that also have energy absorbing characteristics.
