Description
本発明は、継手部を改良した抄紙用ドライヤーカンバス等の工業用織物に関する。 The present invention relates to an industrial fabric such as a paper dryer canvas having an improved joint.
抄紙機のドライヤーパートに使用される抄紙用ドライヤーカンバス（以下、カンバスとも記す。）等の工業用織物は、経糸と緯糸により工業用織物本体を織成し、有端状の工業用織物本体の両端に継手を設け、工業用織物の本体の両端部を連結し無端状として使用されている。従来から、継手部の構造としては、有端状の工業用織物本体の両端部から緯糸を除去して、緯糸を除去することにより露出した簾状の経糸を折り返し、適宜その一部をループ形状とし、折り返された経糸を工業用織物本体に編込むことで、工業用織物本体の両端部に形成された経糸ループ同士を噛み合わせ、噛み合わせて形成される経糸ループ共通孔に接続用芯線を挿通し連結するワープループシーム構造や、前記経糸ループに合成樹脂モノフィラメントからなるスパイラル線条を噛み合わせ、噛み合わせて形成される共通孔にスパイラル線条固定用芯線を挿通し、工業用織物本体の両端部に形成されたスパイラル線条同士を噛み合わせ、噛み合わせて形成されたスパイラル線条共通孔に接続用芯線を挿通して連結するスパイラルシーム構造が一般的に使用されている。 Industrial textiles, such as paper making dryer canvas (hereinafter also referred to as canvas), used in the dryer part of a paper machine, weave the industrial textile body with warps and wefts, and put it on both ends of the end industrial textile body. A joint is provided, and both ends of the main body of the industrial fabric are connected and used as an endless shape. Conventionally, the structure of the joint part is that the wefts are removed from both ends of the end-finished industrial fabric body, the exposed warp-like warp is folded back, and part of it is loop-shaped as appropriate. The warp loops formed on both ends of the industrial fabric main body are meshed with each other by knitting the folded warp into the industrial fabric main body, and the connecting core wire is connected to the warp loop common hole formed by the meshing. The warp loop seam structure to be inserted and connected, the spiral line made of synthetic resin monofilament is meshed with the warp loop, the spiral line fixing core wire is inserted into the common hole formed by meshing, and the industrial textile body Spiral seam structure in which spiral wires formed on both ends are meshed with each other, and a connecting core wire is inserted into and connected to a spiral wire common hole formed by meshing It is commonly used.
従来においては、折り返された経糸の先端部を工業用織物本体に編込む際、通常、図２に示しているように、ループを形成し、工業用織物端部で折り返された経糸１１２と、工業用織物本体側からの折り返されていない経糸１１１とを、これら経糸相互の出会い交差部分で双方の経糸を切断して突き合わせるようにしていた。しかし、これでは、経糸切断糸端に押えがなく遊んでしまうので、抄紙等の操業中のテンション等で折り返された経糸１１２や折り返されていない経糸１１１の糸端が緩み易くなる。 Conventionally, when the folded warp tip is knitted into the industrial fabric body, usually, as shown in FIG. 2, a loop is formed, and the warp yarn 112 folded at the industrial fabric end, An unfolded warp yarn 111 from the industrial fabric main body side is cut and abutted by cutting both warp yarns at the intersection of these warp yarns. However, in this case, since the warp cutting yarn end is not pressed and played, the warp 112 that is folded back by a tension during operation such as papermaking or the warp 111 that is not folded easily becomes loose.
そこで、特許文献１には、図３に示しているように、工業用織物端部で折り返された経糸２１２を、ループ側から見て緯糸１つ分だけさらに遠い側（工業用織物本体側）にある緯糸２１３に絡ませて機械面側に表出させ、工業用織物端部で折り返された経糸２１２と、工業用織物本体側からの折り返されていない経糸２１１の糸端とを一部重ねた状態にして糸上げ切断している構造が提案されている。また、本出願人は、特許文献２において、工業用織物本体の端部から緯糸を除去することにより露出した経糸の一部が折り返されてループを形成し、折り返された経糸の先端部と折り返されていない経糸の先端部が、隣り合う緯糸の間に同一方向から挿入し、工業用織物本体の機械面側で糸上げ切断している構造を提案している。 Therefore, in Patent Document 1, as shown in FIG. 3, the warp yarn 212 folded back at the end of the industrial fabric is further away from the loop side by one weft (the industrial fabric body side). The warp yarn 213 entangled with the weft yarn 213 is exposed to the machine surface side, and the warp yarn 212 folded back at the end portion of the industrial fabric and the end portion of the unfolded warp yarn 211 from the industrial fabric main body side are partially overlapped. A structure has been proposed in which the thread is cut in a state. In addition, in the patent document 2, the applicant of the present invention, a part of the warp exposed by removing the weft from the end of the industrial fabric body is folded back to form a loop, and the tip of the folded back warp is folded back. A structure has been proposed in which the tip of the unwarped warp is inserted between adjacent wefts from the same direction and is threaded and cut on the machine surface side of the industrial fabric body.
しかしながら、特許文献１に記載の抄紙用ドライヤーカンバスにおける糸上げ切断構造においては、図３Ｂ〜３Ｃに示しているように、折り返されていない経糸２１１と折り返された経糸２１２が干渉して隣の経糸を押しのける状態となり、カンバス等の工業用織物の幅方向が圧迫されるという問題がある。 However, in the yarn lifting and cutting structure in the paper making dryer canvas described in Patent Document 1, as shown in FIGS. 3B to 3C, the unfolded warp 211 and the folded warp 212 interfere with each other and the adjacent warp There is a problem that the width direction of industrial fabric such as canvas is pressed.
また、特許文献２に記載の工業用織物の場合、折り返された経糸糸端を周辺の経糸を圧迫することなくカンバス等の工業用織物本体に編込むことができる上、長期間使用によって経糸糸端が切断部付近より緩み、経糸が接紙面側へ浮き出ることを抑えることができるが、二重織以上の多重織の工業用織物の場合、継手作製において、経糸糸端を複雑に通しながらの加工となり時間がかかるため、加工性を改善することが望まれている。 In addition, in the case of the industrial fabric described in Patent Document 2, the folded warp yarn end can be knitted into an industrial fabric body such as a canvas without pressing the peripheral warp, and the warp yarn can be used over a long period of use. The end is loosened from the vicinity of the cutting part, and the warp can be prevented from floating to the paper contact surface side. Since processing takes time, it is desired to improve workability.
本発明は、上記従来の問題を解決するため、工業用織物の端部で折り返された経糸糸端を、周辺の経糸を圧迫せず且つ加工性良く工業用織物本体に編むことができ、経糸糸端が切断部付近より緩み、経糸が接紙面側へ浮き出ることを抑えた抄紙用ドライヤーカンバス等の工業用織物を提供する。 In order to solve the above-mentioned conventional problems, the present invention can knit the warp yarn end folded at the end of the industrial fabric into the industrial fabric main body without compressing the peripheral warp and with good workability. Provided is an industrial fabric such as a dryer canvas for papermaking in which the yarn end is loosened from the vicinity of the cut portion and the warp yarn is prevented from rising to the paper contact surface side.
本発明は、経糸と緯糸を織成した多重織の工業用織物本体の両端を連結する継手部を含む工業用織物であり、上記継手部は上記工業用織物本体の端部から緯糸を除去することにより露出した経糸の一部が折り返されて形成したループを備え、上記折り返された経糸の先端部は機械面側における隣接する３本の緯糸の最もループ側の緯糸に交絡し、折り返されていない経糸の先端部は上記機械面側における隣接する３本の緯糸の最も本体側の緯糸に交絡しつつ、上記折り返された経糸の先端部と上記折り返されていない経糸の先端部は上記機械面側における隣接する３本の緯糸の真ん中の緯糸を挟んで向かい合う方向に挿入され、上記工業用織物本体の機械面側で糸上げ切断されていることを特徴とする工業用織物に関する。 The present invention is an industrial fabric including a joint portion connecting both ends of a multi-woven industrial fabric body woven with warps and wefts, and the joint portion removes the weft from the end portion of the industrial fabric body. A loop formed by folding a part of the warp exposed by the knurl, and the tip of the folded warp is entangled with the weft of the three adjacent wefts on the machine surface side and is not folded The tip of the warp is entangled with the weft of the three main weighs adjacent to each other on the machine surface side, while the tip of the folded warp and the tip of the unfolded warp are on the machine surface side. It is related with the industrial fabric characterized by being inserted in the direction which opposes the weft in the middle of the three adjacent wefts, and being threaded and cut on the machine surface side of the industrial fabric body.
本発明のカンバス等の工業用織物は、工業用織物端部でループを形成して折り返された経糸の先端部を機械面側における隣接する３本の緯糸の最もループ側の緯糸に交絡させ、カンバス等の工業用織物本体側からの折り返されていない経糸の先端部を上記機械面側における隣接する３本の緯糸の最も本体側の緯糸に交絡させつつ、折り返された経糸の先端部と折り返されていない経糸の先端部を上記機械面側における隣接する３本の緯糸の真ん中の緯糸を挟んで向かい合う方向に挿入し、上記工業用織物本体の機械面側で糸上げ切断することにより、折り返された経糸糸端を周辺の経糸を織物幅方向に圧迫せず、無理なくカンバス等の工業用織物本体に編込むことができる。また、工業用織物本体の長手方向に過剰なテンションがかかった場合や長期間使用の場合に経糸が接紙面側へ浮き出ることを抑えることができる。また、接紙面側表面には凸部が無く、継手加工においても編み込み、糸端処理を加工性良く仕上げることができ、生産性が高い。 The industrial fabric such as canvas of the present invention is entangled with the weft yarn of the loop side of the three adjacent wefts on the machine surface side, which is folded back by forming a loop at the end of the industrial fabric, The tip of the unfolded warp from the industrial fabric main body side such as canvas is entangled with the most main weft of the three adjacent wefts on the machine surface side and folded back with the tip of the folded warp. The leading end of the unwarped warp is inserted in a direction facing the middle weft of the three adjacent wefts on the machine surface side, and is turned up by cutting up on the machine surface side of the industrial fabric body. The warp end of the warp yarn can be knitted into an industrial fabric body such as a canvas without any pressure without pressing the peripheral warp in the fabric width direction. Further, when excessive tension is applied in the longitudinal direction of the industrial textile main body or when it is used for a long time, it is possible to suppress the warp from being lifted to the paper contact surface side. Further, there is no projection on the surface of the paper-contacting surface, so that the knitting and yarn end processing can be finished with good workability in joint processing, and the productivity is high.
本発明において、工業用織物は、特に限定されず、例えば、抄紙用ドライヤーカンバス、カッターマシン用の搬送ベルト等の製紙機械用織物、ベルトプレス脱水機をはじめする各種汚泥やスラリーの脱水用機械で用いるフィルターベルト、一般搬送用ベルト、一般乾燥機ベルト等を含む。本発明で継手部とは、工業用織物本体の両端を連結するため、若しくは最先端の緯糸を固定するため、又はスパイラル線条を固定するためのループ部分、及び工業用織物の端部から緯糸を除去することにより露出した経糸の一部が折り返されて、再び工業用織物本体へ編込まれる編込み部分を含む。本発明の工業用織物は、二重織以上の多重織である。多重織は、一重織と比較して、通気性が低く、表面が平滑であり、乾燥効率が高い。 In the present invention, the industrial fabric is not particularly limited. For example, the fabric for papermaking machines such as a dryer canvas for papermaking, a conveyor belt for a cutter machine, and various sludge and slurry dehydrating machines including a belt press dehydrator. Includes filter belts, general conveyor belts, general dryer belts, and the like. In the present invention, the joint portion refers to a loop portion for connecting both ends of an industrial fabric main body, or for fixing a state-of-the-art weft, or for fixing a spiral filament, and a weft from an end portion of an industrial fabric. A part of the warp exposed by removing the folds is folded back and includes a knitted portion that is knitted into the industrial fabric body again. The industrial fabric of the present invention is a double weave or more multi-weave. The multi-woven has a low air permeability, a smooth surface, and a high drying efficiency compared to a single weave.
本発明において、抄紙用ドライヤーカンバス等の工業用織物の継手部ループは、ワープループシーム構造とスパイラルシーム構造のいずれであってもよい。ワープループシーム構造の継手の場合は、剛性のある、しっかりした接合が可能である点、接続用ループが個々の経糸より形成されるため、カンバスの走行時に何らかの原因により接続用ループの一本が切断しても他の接続用ループに影響することのない点で優れている。また、スパイラルシーム構造の継手の場合は、スパイラル線条の形状、素材等を抄紙機のドライヤーパートの雰囲気下に応じて、また使用状況に応じて適宜選択可能であるし、屈曲疲労に強く、芯線挿入が簡易で作業性に優れるという利点がある。 In the present invention, the joint loop of an industrial fabric such as a papermaking dryer canvas may have either a warp loop seam structure or a spiral seam structure. In the case of a joint with a warp loop seam structure, a rigid and firm connection is possible, and since the connecting loop is formed from individual warps, one of the connecting loops is caused by some cause during the travel of the canvas. It is excellent in that it does not affect other connection loops even if it is cut. In addition, in the case of a joint with a spiral seam structure, the shape and material of the spiral filament can be appropriately selected according to the atmosphere of the dryer part of the paper machine and according to the usage situation, and is resistant to bending fatigue, There is an advantage that core wire insertion is simple and excellent in workability.
本発明において、カンバス本体等の工業用織物本体を織成した経糸又は緯糸の素材は、特に限定されず、ポリエチレンテレフタレート等のポリエステル、ポリアミド、ポリフェニレンサルファイド、ポリエーテルエーテルケトン等からなる群から選ばれる一種以上の合成樹脂であることが好ましく、耐久性の観点から、ポリエチレンテレフタレート等のポリエステルであることがより好ましい。また、経糸又は緯糸とも合成樹脂からなるモノフィラメント糸、合成樹脂からなるマルチフィラメント糸等を用いることができる。また、本発明において、スパイラル固定用芯線やスパイラル線条としても、経糸又は緯糸と同様の素材のモノフィラメント糸、マルチフィラメント糸等を用いることができる。 In the present invention, the material of the warp or weft woven from an industrial textile body such as a canvas body is not particularly limited, and is a kind selected from the group consisting of polyester such as polyethylene terephthalate, polyamide, polyphenylene sulfide, polyether ether ketone, and the like. The above synthetic resins are preferable, and polyesters such as polyethylene terephthalate are more preferable from the viewpoint of durability. In addition, a monofilament yarn made of a synthetic resin, a multifilament yarn made of a synthetic resin, or the like can be used for both the warp and the weft. In the present invention, a monofilament yarn, a multifilament yarn, or the like made of the same material as the warp or weft can be used as the spiral fixing core wire or spiral filament.
本発明において、カンバス本体等の工業用織物本体は、二重織以上の多重織であればよく、織り方は特に限定されないが、織物の厚みを薄くできるという観点から二重織が好ましい。また、織組織も、特に限定されず、例えば平織、綾織、朱子織、及び変織等のその他の組織、並びにこれらの組合せのいずれであってもよいが、織物の通気度の調整がしやすいという観点から、２／１綾組織であることが好ましい。 In the present invention, the industrial woven fabric body such as a canvas main body may be a multi-woven fabric having a double weaving or more, and the weaving method is not particularly limited, but the double weaving is preferable from the viewpoint of reducing the thickness of the woven fabric. Also, the woven structure is not particularly limited, and may be any of other structures such as plain weave, twill, satin weaving, and change in weaving, and combinations thereof, but it is easy to adjust the air permeability of the woven fabric. From this viewpoint, a 2/1 twill structure is preferable.
本発明において、カンバス本体等の工業用織物本体の単位長さ当たりの糸の打ち込み本数は、特に限定されないが、経糸が２５〜１３０本／１インチ（２５．４ｍｍ）であり、緯糸が１０〜８０本／１インチ（２５．４ｍｍ）であることが好ましい。より好ましくは、経糸が４０〜１３０本／１インチ（２５．４ｍｍ）であり、緯糸が３０〜８０本／１インチ（２５．４ｍｍ）である。これにより工業用織物の表面の均一性を保持しつつ耐磨耗性を向上させることができる。 In the present invention, the number of yarns driven per unit length of an industrial fabric body such as a canvas body is not particularly limited, but is 25 to 130 warps / 1 inch (25.4 mm) and 10 to 10 wefts. It is preferable that the number is 80/1 inch (25.4 mm). More preferably, the warp is 40 to 130 yarns / inch (25.4 mm), and the weft is 30 to 80 yarns / inch (25.4 mm). Thereby, abrasion resistance can be improved, maintaining the uniformity of the surface of an industrial fabric.
本発明において、経糸又は緯糸の断面形状、線径は、特に限定されないが、円形断面の場合は、直径が０．２〜１．２ｍｍであることが好ましく、直径が０.４〜０．９ｍｍであることがより好ましい。扁平断面の場合は、長辺が０．４〜１．２ｍｍであり、短辺が０．２〜０．８ｍｍであることが好ましく、長辺が０．４〜０．７ｍｍであり、短辺が０．２〜０．６ｍｍであることがより好ましい。これにより工業用織物の表面の均一性を保持しつつ耐磨耗性を向上させ、かつ継手部のバランスをとり、円滑な継手部を形成できる。 In the present invention, the cross-sectional shape and wire diameter of the warp or weft are not particularly limited, but in the case of a circular cross section, the diameter is preferably 0.2 to 1.2 mm, and the diameter is 0.4 to 0.9 mm. It is more preferable that In the case of a flat cross section, the long side is preferably 0.4 to 1.2 mm, the short side is preferably 0.2 to 0.8 mm, the long side is 0.4 to 0.7 mm, and the short side Is more preferably 0.2 to 0.6 mm. As a result, the wear resistance can be improved while maintaining the uniformity of the surface of the industrial fabric, and the joint portion can be balanced to form a smooth joint portion.
また、カンバス本体等の工業用織物本体の単位長さ当たりの糸の打ち込み本数と、経糸及び緯糸の線径が上記の範囲であることにより、編込み部における周辺の経糸に対する影響がより少ない。 In addition, since the number of driven yarns per unit length of the industrial fabric body such as the canvas body and the wire diameters of the warp and the weft are within the above range, the influence on the peripheral warp in the knitted portion is less.
上記工業用織物は、例えば、経糸と緯糸を織成した多重織の工業用織物本体の端部から緯糸を除去することにより露出した経糸の一部を折り返して、上記工業用織物本体の両端を連結する継手部を構成するループを形成し、通常の手法でワープループシーム構造やスパイラルシーム構造の継手部を作製し、上記折り返された経糸の先端部を機械面側における隣接する３本の緯糸の最もループ側の緯糸に交絡させ、折り返されていない経糸の先端部を前記機械面側における隣接する３本の緯糸の最も本体側の緯糸に交絡させつつ、上記折り返された経糸の先端部と上記折り返されていない経糸の先端部を前記機械面側における隣接する３本の緯糸の真ん中の緯糸を挟んで向かい合う方向に挿入し、上記工業用織物本体の機械面側で糸上げ切断することで製造することができる。上記のようにすることで、折り返された経糸糸端を周辺の経糸を織物幅方向に圧迫せず、無理なくカンバス等の工業用織物本体に編込むことができる。また、継手加工において、編み込み、糸端処理を加工性良く仕上げることができ、生産性が高い。 The industrial fabric is, for example, folded back part of the exposed warp by removing the weft from the end of the multi-woven industrial fabric main body woven with warps and wefts, and connects both ends of the industrial fabric main body. Forming a loop that constitutes the joint part to be manufactured, and producing a joint part of a warp loop seam structure or a spiral seam structure by a normal method, and the front end part of the folded warp yarn is made up of three adjacent wefts on the machine surface side. Entangling with the most loop side weft, the front end of the unfolded warp is entangled with the most main weft of the three adjacent wefts on the machine side, and Insert the tip of the unfolded warp in the opposite direction across the middle weft of the three adjacent wefts on the machine surface side, and thread up and cut on the machine surface side of the industrial fabric body It can be produced by. By doing so, the folded warp yarn ends can be knitted into an industrial fabric body such as a canvas without pressing the peripheral warp in the fabric width direction. In joint processing, weaving and yarn end processing can be finished with good workability, and productivity is high.

It is preferable that the cut portions are not arranged in a concentrated manner on the canvas main body but are distributed at different positions. Further, from the viewpoint of not compressing the width direction of the canvas body, it is preferable that the folded warp yarn 12 and the unfolded warp yarn 11 do not interfere with each other in the width direction of the canvas body, that is, the warp yarns do not cross each other.
図１から分かるように、折り返された経糸１２の先端部は機械面側における最もループ側の緯糸２５に交絡し、折り返されていない経糸１１の先端部は機械面側における最も本体側の緯糸２３に交絡しつつ、折り返された経糸１１の先端部と折り返されていない経糸１２の先端部を機械面側における隣接する緯糸２３、２４、２５の真ん中の緯糸２４を挟んで向かい合う方向、すなわち緯糸２４の両側に挿入することにより、周辺の経糸を織物幅方向に圧迫せず、折り返された経糸糸端を無理なくカンバス等の工業用織物本体に編込むことができる。また、折り返された経糸１２の先端部と折り返されていない経糸１１の先端部が機械面側の緯糸に交絡することにより、工業用織物本体の長手方向に過剰なテンションがかかった場合や長期間使用の場合に経糸が接紙面側へ浮き出ることを効果的に抑えることができる。また、折り返された経糸１２の先端部と、折り返されていない経糸１１の先端部が抄紙用ドライヤーカンバスの機械面側で糸上げ切断されていることにより、製品にマークが付くことを効果的に防止することができる。また、接紙面側表面には凸部が無く、継手加工においても編み込み、糸端処理に対し加工性良く仕上げることができ、生産性が高い。 As can be seen from FIG. 1, the front end of the folded back warp 12 is entangled with the weft 25 on the most loop side on the machine surface side, and the front end of the warp 11 that is not folded back is the most weft 23 on the main body side on the machine surface side. , While the front end of the warped yarn 11 and the front end of the unwarped warp 12 are opposed to each other with the weft 24 in the middle of the adjacent wefts 23, 24, 25 on the machine surface side, that is, the weft 24 By inserting them on both sides, it is possible to knit the folded warp yarn end into an industrial fabric body such as a canvas without pressing the surrounding warp in the fabric width direction. Further, the front end portion of the folded back warp 12 and the front end portion of the unfolded warp yarn 11 are entangled with the wefts on the machine surface side, so that excessive tension is applied in the longitudinal direction of the industrial textile body or a long period of time. When used, it is possible to effectively suppress the warp from being raised to the paper contact surface side. In addition, since the leading end of the folded warp 12 and the leading end of the unfolded warp 11 are threaded and cut on the machine surface side of the papermaking dryer canvas, it is possible to effectively mark the product. Can be prevented. Further, there is no projection on the surface on the paper contact surface side, and it can be finished with good workability with respect to knitting and yarn end processing in joint processing, resulting in high productivity.
本発明の工業用織物の一実施形態である抄紙用ドライヤーカンバスは、長時間使用等によって経糸糸端が切断部付近より緩み、接紙面側へ浮き出ることを抑えることができる。例えば、長時間使用しても、編込み部の表面部分の形状変化が少なく、接紙面側の表面性に優れている。 The papermaking dryer canvas which is an embodiment of the industrial fabric of the present invention can prevent the warp yarn end from loosening near the cutting portion and rising to the paper contact surface side after long-time use or the like. For example, even when used for a long time, there is little change in the shape of the surface portion of the knitted portion, and the surface property on the paper contact surface side is excellent.
また、本発明の工業用織物の一実施形態である抄紙用ドライヤーカンバスの片面または両面に合成繊維ウエブをニードリングして重合一体化してなる抄紙用ドライヤーフェルトについても本発明と同様の効果を奏する。 Further, the same effect as that of the present invention can be obtained with a papermaking dryer felt obtained by needling a synthetic fiber web on one or both sides of a papermaking dryer canvas which is an embodiment of the industrial fabric of the present invention. .
