Definitions

  • the invention relates to a belt used for a shoe press mechanism such as a shoe press for papermaking, and especially to a belt used for a closed type shoe press (referred to as “belt” or “shoe press belt” hereinafter.).
  • belts used in a closed type shoe press are subject to more severe conditions in terms of papermaking speed and nip pressure during papermaking process. Accordingly, there has been a strong demand by users for improvement in belt durability.
  • PCT Patent application No. 503315/1989 and Unexamined Japanese Patent Publication No. 209578/1996 disclose a manufacturing method wherein a woven fabric is not used. These manufacturing methods form threads in the axial direction of a mandrel at regular intervals around the entire circumference of the mandrel. However, it is difficult to position threads substantially parallel to the axial direction of a mandrel and without threads being loosen under even tensile force. With these methods, excessive time is required for forming threads.
  • Unexamined Japanese Patent Publication No. 298292/1989 and PCT Patent application No. 505428/1993 disclose a manufacturing method wherein a mat-shaped fiber band or a woven fabric impregnated with uncured resin is wound in helix and then cured.
  • FIG. 10 shows a manufacturing method for a conventional shoe press belt.
  • An endless woven fabric (a woven fabric, which was woven endlessly) C is arranged on two rolls A and B. After a shoe side layer E is impregnated and coated on an external surface of the woven fabric C by a coating apparatus D and is then cured, the endless woven fabric C is removed from the rolls A and B, turned inside-out, and reset on the rolls with its original inner surface facing outward. After a wet paper web side layer F is impregnated and coated on the external surface of the fabric and is cured with its entire thickness adjusted, concave grooves G are formed, and a belt 1 is produced.
  • the above-described conventional method had the following two deficiencies: 1) in order to impregnate and coat the shoe side layer E on one surface of the endless woven fabric and the wet paper web side layer F on the other side, the belt needed to be reversed, and reversal caused distortion to occur inside the belt; 2) the distortion that existed when weaving the endless woven fabric is released as the resin is cured, which results in instability of the form of the belt due to flapping of the belt.
  • Japanese Patent No. 3408416 and Unexamined Japanese Patent Publication No. 303377/2000 disclose a manufacturing method wherein a resin layer is firstly formed on a mandrel followed by formation of a base body, i.e., a substrate, around the external circumference of the resin layer, and formation of another resin layer, which is connected with first resin layer through the base body.
  • a base body i.e., a substrate
  • the shoe press belt manufactured according to the manufacturing method disclosed in the Japanese Patent No. 3408416 has relatively large undulations at the joints of warp yarns and weft yarns in the woven fabric because a woven fabric piece is used as a base body.
  • these undulations result in large stress concentration at the joints of warp yarns and weft yarns, which can result in cracking of a resin layer, and impairment of the durability of the belt.
  • prior Japanese Patent Application No. 76216/2005 proposed a shoe press belt comprising a base body having a lattice material made by joining the crossing points of warp yarns and weft yarns crossing one another at crossing points and joined at the crossing points and a layer comprising thread wound in helix, a wet paper web side layer; and a shoe side layer formed on a mandrel having a polished surface.
  • compressed air indwells in press rolls wearing the above shoe press belt, it is employed in the condition that tensile force is loaded on the entire belt.
  • the shoe press belt runs in the MD direction with drive at a roll axis and said tensile force increases at a position immediately before the press and decreases at the press exit.
  • the problems are that the strength of the belt in the CMD direction be deteriorated or that the belt is subject to dilatation in the CMD direction since the weft yarns are more easily worn than the warp yarns.
  • a shoe press belt to be disposed between press rolls and a shoe of a shoe press apparatus, comprising a base body consisting of a lattice material made by joining the crossing points of warp yarns and weft yarns and a thread layer wound in a helix, a wet paper web side layer and a shoe side layer formed on a mandrel having a polished surface, characterized in that said warp yarns are so formed as to wear earlier than said weft yarns.
  • the weft yarns of the lattice material are more likely to be worn than the weft yarns, the weft yarns do not wear off early as before. As a result, strength and dimensional stability of the belt are improved.

  • FIG. 9 The apparatus employed to examine abrasion resistance is shown in FIG. 9 .
  • both edges of the experimental piece 13 are pinched by clamp hands CH, CH, which are interlocked with one another and reciprocally movable in the same direction as the arrow A.
  • An evaluation surface of the experimental piece 13 faces the rotating roll RR 1 .
  • the experimental piece 13 is compressed by moving the press shoe PS toward the roll RR 1 .
  • the lattice material and the thread layer wound in a helix are on the rotating roll side of the experimental piece 13 , and stress from the inflection therein is not so much high.
  • this apparatus therefore, abrasion degree at the crossing points of the warp yarns and the weft yarns of the lattice material can be examined.
  • the test was continued until the number of reciprocation reaches 500000 times, and by measuring breaking strengths of the experimental piece 13 both in the warp direction and the weft direction after the test, abrasion property of the lattice material of the experiment piece 13 was observed.

  • the breaking strength and the abrasion property of the lattice material in Table 1 are the results of the measurement of breaking strengths of the warp yarns and the weft yarns of the lattice material by digesting the belt of the invention after the test in an organic solvent of dimethyl formamide, dissolving polyurethane covering the lattice material, taking out the lattice material which remains without being dissolved; and measuring breaking strengths of the warp yarn and the weft yarns of the lattice material and observing the condition of the crossing points of the lattice material.
  • abrasion resistance of the weft yarns is superior in all the embodiments is because the warp yarns crossing the weft yarns are made by threads that have more tendency to be worn, so that when friction occurs in the crossing points of the weft yarns and the warp yarns along with the experimental piece 13 under the experiment curves, the warp yarns are torn prior to the weft yarns. As a result, damage to the weft yarns was reduced. Therefore, since less abrasion occurs to the weft yarns of the invention, breaking strength in the latitudinal direction is held and dimensional stability is also maintained.
  • spun yarns of polyester cotton are formed by making and twisting a carding web using short fibers of polyester, and in general, crimps (curl) are formed in the short fibers in a manufacturing process thereof. Therefore, the spun yarns obtained in such a way have a convexo-concave surface.
  • polyester cotton having a convexo-concave surface is more likely to be worn than the twisted yarns of multi-filament. The above are verified by example 1.
  • Cotton as a material has a greater tendency to be worn than polyester cotton. This can be drawn from example 2.
  • the forms of the fibers (including the thickness) or the combination of the materials may be selected appropriately.
  • a thread 50 A of the wound layer has a strength of 100 to 300 kg/cm, so that the strength of the warp yarns of the belt can be kept sufficiently by the wound layer.
  • the invention reduced the abrasion of the weft yarns when the belt is in use, by applying the lattice material comprising the warp yarns being more likely to be worn than the weft yarns.
  • the dimensional stability in the CMD direction of the belt is improved and accordingly the strength and the durability of the belt are also improved.
