Description

【0001】
【発明の属する技術分野】
本発明は製紙用織物、搬送ベルト、ろ布等の工業用織物に関するものである。
【0002】
【従来の技術】
従来から工業用織物としては経糸、緯糸で製織した織物が広く使用されており、例えば製紙用ワイヤーや搬送用ベルト、ろ布等その他の多くの分野で使用されており、用途や使用環境に適した織物特性が要求されている。特に織物の網目を利用して原料の脱水等を行う製紙工程で使用される抄紙用ワイヤーでの要求は厳しく、紙に織物のワイヤーマークを転写することのない表面性に優れた織物、また過酷な環境下においても好適に使用できる程度の剛性を持ち合わせたもの、そして良好な紙を製造するために必要な条件を長期間持続することのできる織物が要求されている。その他にも繊維支持性、製紙の歩留まりの向上、良好なろ水性、耐摩耗性、寸法安定性、走行安定性等が要求されている。さらに近年では抄紙マシンが高速化しているため、それに伴い抄紙用ワイヤーへの要求も一段と厳しいものとなっている。
このように工業用織物の中でも要求が厳しい抄紙用織物について説明すればほとんどの工業用織物の要求とその解決について理解できるので、以下抄紙用織物を代表して本発明を説明する。
例えば、抄紙スピードが高速になると必然的に脱水スピードが高速になり、脱水力を強力にする必要がある。それによって当然繊維や填料等の抜け、ワイヤーマークの発生は顕著になるため、さらなる繊維支持性、表面性の改良が必要となる。また、抄紙用織物に湿紙のくい込みが大きくなったり、繊維のささり込みが発生すると湿紙をフェルトへ移送する場合の湿紙剥離性が悪くなるという問題も発生する。織物上に残って形成された湿紙は脱水力によって、織物表面に押し付けられるため、糸が存在している部分では糸が湿紙にくい込み、逆に糸が存在しない網目間では湿紙が網目にくい込んで湿紙表面上に糸と網目のマークを発生させるためである。ワイヤーマークを完全になくすことは不可能であるが、これを極力小さく目立たなくするためには織物の上層表面を細かくし、表面平滑性、及び繊維支持性の向上を図らなくてはならない。しかし、表面性や繊維支持性を重視した目の細かい織物は、基本的に線径の小さい糸で製織されているため耐摩耗性には劣っていた。
また、抄紙用織物は高速で走行するためマシンと接触する側の走行面側ではロール等との摩擦によって織物が次第に摩耗していく現象がみられ、摩耗によって寿命が尽きてしまうこともある。耐摩耗性を向上させるには織物組織を緯糸摩耗型の組織にしたり、糸の材質を変更したりと様々な対策が必要とされ、特に線径の大きい糸を用いることで耐摩耗性を付与する方法が一般的に用いられている。しかし、線径の大きい糸は耐摩耗性は向上するものの優れた表面性を得ることは困難であった。
表面性と耐摩耗性の両方の問題を解決するために、上面側層と走行面側層にそれぞれ別の経糸、緯糸を用いて構成した2枚の織物を使用し、両層の織物を接結糸によって一体化させた2層織物が用いられてきた。この方法はそれぞれに要求される性能に応じた織物を採用できるという効果があった。上面側層に線径の小さい経糸、緯糸を用いて緻密な上層面を形成し、走行面側層に線径の大きい経糸、緯糸を使用して耐摩耗性の大きい走行面を形成した。接結糸には表面性を低下させないために一般的に上面側経糸、上面側緯糸より小径の糸が使用された。上面側層組織は緻密な表面を形成するために平織が使用されることが多いが、実際には2つの層を織り合わせるために接結糸が用いられるので、実質平織表面に接結糸が所々に配置された表面が形成されることとなる。接結糸はこのように表面に現れる部分も存在するため、表面平滑性の問題から線径のあまり大きい糸を使用することは好ましくはなかった。
また、通常製紙用織物は使用時には経方向に張力が掛けられることが多く、経方向の糸は常に張力が掛けられている状態であるので織物の走行によって経糸がゆるみ移動することはほとんどないが、製織性や繊維支持性等の問題から緯糸間に配置されることの多い接結糸では張力が掛かると伸びたり、上面側層と走行面側層の間で接結糸が揉まれて内部摩耗が発生し、織物間に隙間が発生したり分離してしまうという問題が生じることがあった。これは無端状ベルトがいくつかのロールに掛けられて走行しているためであり、ロールに織物が接触する部分ではロールの弧に沿って2層織物が湾曲し織物の各層で周長差が生じるからである。それによって各層を織り合わせている接結糸は揉まれ、内部摩耗が発生するのである。内部摩耗は表面性向上のために使用されている線径が小さく強度の低い接結糸でよく見受けられる。線径の小さい接結糸のみでの上面側層、走行面側層の接結は接結力が不十分であった。また接結糸は2枚の織物を連結するために上面側層の糸に絡み、接結力によって糸を引き込むために上面側表面に凹みを与えて織物の表面性を悪化させてしまうという問題もあった。
そこで、経方向の糸に上面側表面を形成しつつも上面側層と走行面側層を織り合わせる経糸地糸接結糸を用いた多層織物の開発がされてきた。上面側層では上面側表面を形成する経糸に上面側経糸と組を形成する経糸地糸接結糸を用い、上面側緯糸と織り合わせて上面側表面を形成した。走行面側層は走行面側経糸と走行面側緯糸によって形成した。さらに接結力の向上や目開きの均一化を目的として、上面側層を形成する経糸の全てを経糸地糸接結糸とした織物等も開発された。しかし、従来の経糸地糸接結糸によって接結した多層織物は1本の走行面側経糸の隣に2本1組の経糸地糸接結糸を配置する構造とした。1組の経糸地糸接結糸は常に同じ走行面側経糸の隣りに隣接配置されるため、走行面側層では2本の経糸地糸接結糸は一方の走行面側経糸の横に偏って配置される。同様に上面側層でも組を形成する2本の経糸地糸接結糸が走行面側層と同様に偏って配置されるため、ろ水空間の均一性が確保できず、均一な脱水を行うことができないという問題があった。
【0003】
【発明が解決しようとする課題】
本発明は上記の問題に鑑みて、上面側緯糸と織り合わされて上面側表面の一部を形成しつつ上面側層と走行面側層を連結する経糸地糸接結糸を2本1組で配置し、走行面側では組を形成する2本の経糸地糸接結糸をそれぞれ両隣の走行面側経糸に近接させ、上面側では組を形成する2本の経糸地糸接結糸が交互に上面側表面に現れて、それらが互いに接近して走行面側経糸間のほぼ中央の上方で実質経糸1本分の組織を形成する構造とすることで織物のろ水性を均一にし、また接結力、表面平滑性に優れた工業用多層織物を提供しようとするものである。

【発明の実施の形態】
本発明の工業用織物は製紙用ワイヤー、搬送用ベルト、ろ布等の工業用織物として使用するものであり、特にはユーザーからの要求の厳しい抄紙用ワイヤーとしても好適に使用することができる。
本発明は少なくとも上面側層と走行面側層を備え、上面側層の一部を形成する経糸地糸接結糸によって上面側層と走行面側層を連結してなる工業用多層織物であり、上面側経糸の一部または全部を経糸地糸接結糸とした。経糸地糸接結糸は織物の走行方向に2本1組で配置し、上面側経糸と共に、または経糸地糸接結糸単独で上面側表面を形成し、2本の経糸地糸接結糸のうち一方が上面側表面にあるときは、他方の糸が上面側層の下側に存在しており、交互に上面側表面に現れて実質上面側経糸1本分の組織を形成する組織とし、上面側緯糸と織り合わされて上面側表面の一部を形成する。走行面側層では組を形成する2本の経糸地糸接結糸のうち一方の経糸地糸接結糸はその糸と近い方の走行面側経糸に近接し、他方の経糸地糸接結糸はその糸と近い方の走行面側経糸に近接して互いに離れ、一方上面側では組を形成する2本の経糸地糸接結糸が互いに接近して走行面側経糸間のほぼ中央の上方で実質上面側経糸1本分の組織を形成する構造とした。この多層織物は2つの層を連結する接結糸に経方向に配置された経糸地糸接結糸を使用しているため接結力が強く、該経糸地糸接結糸は2つの層を接結しつつも上面側層の一部を形成するため表面平滑性に優れ、また上面側表面では組になった2本の経糸地糸接結糸が走行面側経糸間のほぼ中央の上側で実質経糸1本分の組織を形成するため織物表面全体に均一な網目空間を与え、ろ水性が均一となる。
【0006】
本発明のように織物走行方向に2つの層を織り合わせる経糸地糸接結糸を配置することによる一番の効果は、従来の接結するだけで表面組織形成に関与しない接結糸とは異なり、該経糸地糸接結糸が織物表面の一部として機能するため局所的な凹みの発生がないということである。また経糸地糸接結糸は経方向、つまり一般的にいう織物の走行方向に伸びて常に張力がかけられた状態で使用されるため糸のたるみの発生がなく、織物構造から見ても接結力が強い傾向にある。
そして経糸地糸接結糸を経糸間に2本1組で配置し、走行面側層では組を形成する2本の経糸地糸接結糸のうち一方の経糸地糸接結糸はその糸に近い方の走行面側経糸に隣接配置し、他方の経糸地糸接結糸はその糸に近い方の走行面側経糸に隣接配置した構造とすることで、走行面側層では組になった経糸地糸接結糸が離れて配置され、それによって比較的大きなろ水空間を確保することができる。また、上面側層では2つの走行面側経糸間のほぼ中央の上方に実質上面側経糸1本分の組織を形成する。つまり、上面側層を形成する経方向の糸が全て等間隔で配置されるため上面側層に均一なろ水空間が配置されるのである。
また、走行面側経糸が走行面側緯糸の下側を通過するところで、それに隣接する1本の経糸地糸接結糸が同じ走行面側緯糸の下側を通る構造とするのが好ましい。つまり2本1組の経糸地糸接結糸のうち左側の経糸地糸接結糸は、その左側に配置されている走行面側経糸が走行面側緯糸の下側を通過するところで、該経糸地糸接結糸が同じ走行面側緯糸の下側を通る構造とし、2本1組の経糸地糸接結糸のうち右側の経糸地糸接結糸は、その右側に配置されている走行面側経糸が走行面側緯糸の下側を通過するところで、該経糸地糸接結糸が同じ走行面側緯糸の下側を通る構造とする。このような構造とすることで、各経糸地糸接結糸がそれぞれ両側の走行面側経糸に近接配置されるので、2本の経糸地糸接結糸が走行面側層で離れて配置され、走行面側層に比較的大きなろ水空間を形成することができる。また、一般的に走行面側経糸よりも小径である経糸地糸接結糸の摩耗を軽減させることもできる効果もある。
【0007】
上面側層を形成する経糸に上面側経糸と経糸地糸接結糸の両方を用いる方法と、経糸地糸接結糸のみとする方法がある。織物を構成する上面側経糸、経糸地糸接結糸、走行面側経糸等それぞれの組織は特に限定されていないが、上面側層は湿紙に織物のマークを付与しにくい構造とすることが望ましく、また走行面側層は織物の走行によって生じる摩耗に耐性のある構造とすることが好ましい。走行面側では走行面側層に走行面側経糸を配置し、その間に組になった経糸地糸接結糸を配置すればよい。
組になった経糸地糸接結糸の組織については同一であっても、異なっても構わない。異なる組織の経糸地糸接結糸を用いる例として、1本の上面側緯糸と1本の上面側緯糸の下側を交互に通過して上面側表面に6個のナックルを形成し、次いで5本の上面側緯糸の下側を通過し、次いで1本の走行面側緯糸の下側を通過し、次いで7本の上面側緯糸の下側を通過する組織の経糸地糸接結糸と、この経糸地糸接結糸とは進行方向逆向きとした組織とを2本組み合わせて形成したものがある。この逆向きの組織は隣り合う走行面側経糸と経糸地糸接結糸が隣接して同じ走行面側緯糸の下側を通る組織としたためにこのようになっただけであり、特別なものではない。好ましくはこの例のように、1本の走行面側緯糸が隣接する走行面側経糸と経糸地糸接結糸の両方を織り込んだ、つまり隣り合う走行面側経糸と経糸地糸接結糸が隣接して同じ走行面側緯糸の下側を通る組織とした方が走行面側層のろ水空間の確保、経糸地糸接結糸の安定性の確保ができ、また摩耗対策にもなる。
この組織は経糸地糸接結糸2本を組み合わせて上面側表面に平織を形成する組織とした。織物表面を平織構造とすると繊維支持点数が増加するため繊維支持性が向上し、また織り目が細かくなるため表面平滑性にも優れるという効果がある。このように上面側層を形成する経糸地糸接結糸は、2本1組で紙にマークを付与しない組織とすることが好ましい。また経糸地糸接結糸が異なる組織の場合、それらを1組ごとに左右逆に組み合わせて配置してもよい。これは織物表面に現れる斜めマークを崩すことができるためであり、織物表面性を重視する製紙用織物等において好適である。
走行面側経糸の組織も特に限定されてはなく、経糸地糸接結糸との組み合わせ等によって適宜決定するとよい。
【0008】
また、本発明に使用される糸は用途、あるいは織物上での各糸の機能によって選択すればよく、例えば、モノフィラメントの他、マルチフィラメント、スパンヤーン、捲縮加工や嵩高加工等を施した一般的にテクスチャードヤーン、バルキーヤーン、ストレッチヤーンと称される加工糸、あるいはこれらを撚り合わせる等して組み合わせた糸が使用できる。また、糸の断面形状も円形だけでなく四角形状や星型等の短形状の糸や楕円形状、中空等の糸が使用できる。また、糸の材質としても、自由に選択でき、ポリエステル、ナイロン、ポリフェニレンサルファイド、ポリフッ化ビニリデン、ポリプロ、アラミド、ポリエーテルエーテルケトン、ポリエチレンナフタレート、ポリテトラフルオロエチレン、綿、ウール、金属等が使用できる。もちろん、共重合体やこれらの材質に目的に応じてさまざまな物質をブレンドしたり含有させた糸を使用してもよい。
【0009】
抄紙用ワイヤーとしては一般的には、上面側経糸、走行面側経糸、上面側緯糸には剛性があり、寸法安定性に優れるポリエステルモノフィラメントを用いるのが好ましい。また、経糸地糸接結糸としては上面側経糸同様ポリエステルモノフィラメントを用いるのが好ましい。上面側経糸と経糸地糸接結糸の糸の種類や線径等は同じであっても、異なるものであってもよく、織物の性質や製織性等から随時選択できる。しかし、上面側経糸と経糸地糸接結糸では役割が異なり、また経糸地糸接結は2本1組で経糸間に配置されることが多いことから、線径等異なる糸を用いた方が好ましい。
また、耐摩耗性が要求される走行面側緯糸にはポリエステルモノフィラメントとナイロンモノフィラメントを交互に配置する等、交織するのが剛性を確保しつつ耐摩耗性を向上できるため好ましい。それぞれの線径についても用途や適正に合わせて選択すればよく、一般的には上面側層を形成する上面側経糸、上面側緯糸には比較的小径の糸を使用することが好ましく、走行面側層を形成する走行面側経糸、走行面側緯糸には比較的大径の糸を使用することが好ましい。また、2本1組で上面側表面を形成しつつも上面側層と走行面側層を織り合わせる経糸地糸接結糸は2本1組で配置されることから上面側経糸よりも小径であるものが好ましいが、用途や目的の物性等に合わせて適宜変更するとよい。
【0010】
【実施例】
発明の実施の形態を実施例にもとづき図面を参照して説明する。
図1、2は本発明の実施例の完全組織を示す意匠図である。完全組織とは、織物組織の最小の繰り返し単位であって、この完全組織が上下左右につながって織物全体の組織が形成される。また図3は図2の意匠図の緯糸15´の断面図、図4は図2の意匠図の緯糸1´の断面図である。
意匠図において、経糸、経糸地糸接結糸はアラビア数字、例えば、1、2、3・・・で示した。経方向の糸のうち奇数番号、例えば1,3,5・・・は上面側経糸、走行面側経糸が上下に配置されている。偶数番号2,4,6・・・は組になった経糸地糸接結糸であり、2aと2b、3aと3b・・・24aと24bが組になって経糸間に2本1組で配置されている。緯糸はダッシュを付したアラビア数字、例えば1´、2´、3´で示した。それぞれ上面側緯糸と走行面側緯糸が上下に配置されている。×印は上面側経糸、または経糸地糸接結糸が上面側緯糸の上側を通ってナックルを形成していることを示し、○印は走行面側経糸が走行面側緯糸の下側に位置していることを示し、△印は経糸地糸接結糸が走行面側緯糸の下側に位置していることを示す。
本実施例では上面側緯糸と走行面側緯糸、上面側経糸と走行面側経糸が意匠図上において、便宜上上下に重なって配置されているが、実際の織物ではずれて配置されることがある。また組になった経糸地糸接結糸a,bは意匠図上で並列に配置されているが、実際には上下に重なって配置されている部分がある。
【0011】
実施例1
図1の意匠図において本実施例は経糸地糸接結糸、上面側経糸、上面側緯糸、走行面側経糸、走行面側緯糸からなる2層織物である。上面側層を形成する経糸に上面側経糸と経糸地糸接結糸を配置し、経糸間に配置された2本1組の経糸地糸接結糸によって上層、下
層を織り合わせたものである。
図1の実施例は経糸間に2本1組の経糸地糸接結糸が配置されており、これらの1本が上面側表面に現れているとき、他方は上面側表面の下にあり、このようにして上面側緯糸と織りなし上面側表面に実質経糸1本分の組織を形成する組織とした。2本1組の経糸地糸接結糸は1本の上面側緯糸の上側、下側を通って実質経糸1本分の平織組織を形成している。走行面側においては組を形成する2本の経糸地糸接結糸のうち、意匠図上で左側に配置している経糸地糸接結糸(aを付した糸)はその左側に配置している経糸に近接して配置され、もう一方の経糸地糸接結糸(bを付した糸)はその右側に配置している経糸に近接して配置される。これは経糸地糸接結糸が走行面側経糸と一緒に一本の走行面側緯糸によって織り込まれたからであり、走行面側経糸より小径な経糸地糸接結糸は、該走行面側経糸側に移動し接近して配置されることになる。
つまり、走行面側層では組になった経糸地糸接結糸が離れて配置されることとなるため、その間には比較的大きなろ水空間が形成され、ろ水性に優れた織物となる。
また、上面側層では組を形成する2本の経糸地糸接結糸が互いに接近して走行面側経糸間のほぼ中央の上方に位置して、上面側緯糸と織り合わされて実質経糸1本分の平織組織を形成する。組になった経糸地糸接結糸は一方が上面側層を形成しているところの下側で、もう一方が走行面側緯糸の下側を通って二つの層を織り合わせているため、二本が同時に上面側層に隣接配置されることはなく交互に上面側表面に現れる。それによって組になった経糸地糸接結糸のうち意匠図上で左側に配置されている糸は上面側層を形成しているとき、組になったもう一方の経糸地糸接結糸が上面側層に現れていないため、意匠図上の右側に移動する力が働く。一方右側に配置されている経糸地糸接結糸は組になったもう一方の経糸地糸接結糸が上面側層に現れていないため、意匠図上の左側に移動する力が働く。これによって二本の経糸地糸接結糸は互いに向かい合う方向に力が働き、経糸間のほぼ中央で上面側表面に一本の上面側経糸のような組織を形成する。また上面側経糸も平織組織を形成しているため、上面側表面は組になった経糸地糸接結糸と上面側経糸、そして上面側緯糸によって平織組織が形成される。また経糸地糸接結糸を上記構造としたことで、上面側表面を形成する経糸間には均一なろ水空間を形成する。
図1は本発明の実施例の一つであり、異なる組織の経糸地糸接結糸を経糸間に2本1組で配置し、走行面側層では組を形成する2本の経糸地糸接結糸がそれぞれに隣接する走行面側経糸に近接配置し、上面側層では2つの走行面側経糸間のほぼ中央の上方に1本の経糸地糸接結糸が上面側表面に現れている場合は、他方が上面側表面の下側にあって実質経糸1本分の組織を形成する。
該経糸地糸接結糸は1本の上面側緯糸の上側と下側を交互に通過して上面側表面に6個のナックルを形成し、5本の上面側緯糸と走行面側緯糸の間を通過し、次いで1本の走行面側緯糸の下側を通過し、次いで7本の上面側緯糸と走行面側緯糸の間を通過する組織の経糸地糸接結糸と、この経糸地糸接結糸とは進行方向逆向きとした組織とを2本組み合わせて形成したものである。詳しくは経糸地糸接結糸2を例にあげると、経糸地糸接結糸2aは、1本の走行面側緯糸1’の下側を通り、次いで7本の上面側緯糸2’,3’,4’,5’,6’,7’,8’と走行面側緯糸の間を通り、次いで1本の上面側緯糸9’の上側を通って上面側表面にナックルを形成し、1本の上面側緯糸10’と走行面側緯糸10’の間を通り、1本の上面側緯糸11’の上側を通って上面側表面にナックルを形成し、1本の上面側緯糸12’と走行面側緯糸12’の間を通り、1本の上面側緯糸13’の上側を通って上面側表面にナックルを形成し、1本の上面側緯糸14’と走行面側緯糸14’の間を通り、1本の上面側緯糸15’の上側を通って上面側表面にナックルを形成し、1本の上面側緯糸16’と走行面側緯糸16’の間を通り、1本の上面側緯糸17’の上側を通って上面側表面にナックルを形成し、1本の上面側緯糸18’と走行面側緯糸18’の間を通り、1本の上面側緯糸19’の上側を通って上面側表面にナックルを形成し、次いで5本の上面側緯糸20’,21’,22’,23’,24’と走行面側緯糸の間を通る組織である。それと対になるもう一方の経糸地糸接結糸2bは1本の上面側緯糸1’の上側を通って上面側表面にナックルを形成し、1本の上面側緯糸2’と走行面側緯
糸2’の間を通り、1本の上面側緯糸3’の上側を通って上面側表面にナックルを形成し、1本の上面側緯糸4’と走行面側緯糸4’の間を通り、1本の上面側緯糸5’の上側を通って上面側表面にナックルを形成し、1本の上面側緯糸6’と走行面側緯糸6’の間を通り、1本の上面側緯糸7’の上側を通って上面側表面にナックルを形成し、7本の上面側緯糸8’,9’,10’,11’,12’,13’,14’と走行面側緯糸の間を通り、次いで1本の走行面側緯糸15’の下側を通り、5本の上面側緯糸16’,17’,18’,19’,20’と走行面側緯糸の間を通り、1本の上面側緯糸21’の上側を通って上面側表面にナックルを形成し、次いで1本の上面側緯糸22’と走行面側緯糸22’の間を通り、1本の上面側緯糸23’の上側を通って上面側表面にナックルを形成し、次いで1本の上面側緯糸24’と走行面側緯糸24’の間を通る組織である。この対になった経糸地糸接結糸は2aと2bは進行方向、つまり意匠図の上下方向でみると、組織が逆になっている。
これらの2本の経糸地糸接結糸2a,2bは意匠図上では、並列して2本の経糸1,3の間に配置されているが、実際は走行面側層においては経糸地糸接結糸2aは走行面側経糸1と一緒に走行面側緯糸1’によって織り込まれているため、走行面側経糸1よりも小径な経糸地糸接結糸2aは走行面経糸1側に移動して走行面側経糸1に近接配置しており、また経糸地糸接結糸2bは走行面側経糸3と一緒に走行面側緯糸1によって織り込まれているため、走行面側経糸3よりも小径な経糸地糸接結糸2bは走行面経糸3側に移動して走行面側経糸3に近接配置している。これは走行面側経糸が走行面側緯糸の下側を通るところで、それに近接している経糸地糸接結糸が同じ走行面側緯糸の下側を通る構造としたためである。組になった経糸地糸接結糸がそれぞれ両側の走行面側経糸に近接することで、走行面側層には比較的大きなろ水空間を形成することができろ水性を向上させることができる。その他に経糸地糸接結糸の走行面側ナックルを走行面側経糸の走行面側ナックルに隣接配置したことで、経糸地糸接結糸の糸の移動がなく安定した織物とすることができ、また走行面側経糸よりも線径の小さい経糸地糸接結糸の摩耗を軽減させる効果もある。
上面側層では組になった経糸地糸接結糸が交互に上面側表面に現れ、上面側緯糸と織り合わされて1本の経糸として機能しており、経糸地糸接結糸2においては、経糸地糸接結糸2aが上面側緯糸9’,10’,11’,12’,13’,14’,15’,16’,17’,18’,19’と織り合わされているところの下側で、経糸地糸接結糸2bが走行面側緯糸15’の下側を通り、上層と下層を織り合わせている。また経糸地糸接結糸2bが上面側緯糸21’,22’,23’,24’,1’,2’,3’,4’,5’,6’,7’と織り合わされているところの下側で、経糸地糸接結糸2aが走行面側緯糸1’の下側を通り、上層と下層を織り合わせている。そして、経糸地糸接結糸2a、及び経糸地糸接結糸2bは、走行面側経糸1と走行面側経糸3のほぼ中央の上方で1本の経糸のように機能して、上面側緯糸と織り合わされて平織組織を形成している。これは組になった経糸地糸接結糸のうち、一方の経糸地糸接結糸が上面側層を形成しているときにもう一方の経糸地糸接結糸が上面側層に現れてなく、2本の経糸地糸接結糸は交互に上面側表面を形成しているため互いに向かい合う方向に力が働き、経糸間のほぼ中央で1本の上面側経糸のように機能する。
また、経糸地糸接結糸の両側に配置している経糸も、上面側では経糸地糸接結糸と上面側経糸、そして上面側緯糸が織り合わされて上面側表面全体に平織組織を形成する。平織組織は緻密な表面を形成することができるため平滑性に優れ、また均一なろ水空間を確保できる。
緯方向には上面側緯糸、走行面側緯糸が上下同じ本数で配置されているが、その他の配置割合としてもよく、走行面側層は織物の走行によって生じる摩耗に耐え得る緯糸摩耗型組織としている。走行面側緯糸1’では1本の走行面側経糸1と経糸地糸接結糸2aの上側を通った後、連続した5本の走行面側経糸3,5,7,9,11と、その間に存在する経糸地糸接結糸の下側を通り、次いで1本の走行面側経糸13と経糸地糸接結糸14aの上側を通り、5本の走行面側経糸15,17,19,21,23と、その間に存在する経
糸地糸接結糸の下側を通って走行面側緯糸が走行面側経糸5本分のロングナックルを形成する組織とした。
ここでは、上面側経糸1,走行面側経糸1,経糸地糸接結糸2,走行面側緯糸1’を例にあげて説明したが、その他の構成糸も同様の組織とすることで、表面平滑性、接結力に優れ、均一なろ水性を有する工業用多層織物を提供することができる。

実施例2
図2は本発明の他の実施例の一つであり、異なる組織の経糸地糸接結糸を経糸間に2本1組で配置し、走行面側層では組を形成する2本の経糸地糸接結糸がそれぞれに隣接する走行面側経糸に近接配置し、上面側層では2つの走行面側経糸間のほぼ中央の上方に組になった経糸地糸接結糸が上面側表面に交互に現れて実質経糸1本分の組織を形成する。
該経糸地糸接結糸は1本の上面側緯糸の上側と下側を交互に通過して上面側表面に5個のナックルを形成し、次いで3本の上面側緯糸と走行面側緯糸の間を通過し、次いで1本の走行面側緯糸の下側を通過し、次いで7本の上面側緯糸と走行面側緯糸の間を通過する組織の経糸地糸接結糸と、この経糸地糸接結糸とは進行方向逆向きとした組織とを2本組み合わせて形成したものである。詳しくは経糸地糸接結糸2を例にあげると、経糸地糸接結糸2aは、1本の走行面側緯糸1’の下側を通り、次いで7本の上面側緯糸2’,3’,4’,5’,6’,7’,8’と走行面側緯糸の間を通り、次いで1本の上面側緯糸9’の上側を通って上面側表面にナックルを形成し、1本の上面側緯糸10’と走行面側緯糸10’の間を通り、1本の上面側緯糸11’の上側を通って上面側表面にナックルを形成し、1本の上面側緯糸12’と走行面側緯糸12’の間を通り、1本の上面側緯糸13’の上側を通って上面側表面にナックルを形成し、1本の上面側緯糸14’と走行面側緯糸14’の間を通り、1本の上面側緯糸15’の上側を通って上面側表面にナックルを形成し、1本の上面側緯糸16’と走行面側緯糸16’の間を通り、1本の上面側緯糸17’の上側を通って上面側表面にナックルを形成し、3本の上面側緯糸18’,19’,20’と走行面側緯糸の間を通る組織である。それと対になるもう一方の経糸地糸接結糸2bは1本の上面側緯糸1’の上側を通って上面側表面にナックルを形成し、1本の上面側緯糸2’と走行面側緯糸2’の間を通り、1本の上面側緯糸3’の上側を通って上面側表面にナックルを形成し、1本の上面側緯糸4’と走行面側緯糸4’の間を通り、1本の上面側緯糸5’の上側を通って上面側表面にナックルを形成し、1本の上面側緯糸6’と走行面側緯糸6’の間を通り、1本の上面側緯糸7’の上側を通って上面側表面にナックルを形成し、7本の上面側緯糸8’,9’,10’,11’,12’,13’,14’と走行面側緯糸の間を通り、次いで1本の走行面側緯糸15’の下側を通り、3本の上面側緯糸16’,17’,18’と走行面側緯糸の間を通り、1本の上面側緯糸19’の上側を通って上面側表面にナックルを形成し、次いで1本の上面側緯糸20’と走行面側緯糸20’の間を通る組織である。この対になった経糸地糸接結糸2aと2bは進行方向からみて逆向きとなった組織である。
これらの2本の経糸地糸接結糸は意匠図上では、並列して2本の経糸1,3の間に配置されているが、走行面側層においては経糸地糸接結糸2aは走行面側経糸1に近接配置している。また経糸地糸接結糸2bは走行面側経糸3に近接配置している。これは走行面側経糸が走行面側緯糸の下側を通るところで、それに近接している経糸地糸接結糸が同じ走行面側緯糸の下側を通る構造としたためである。組になった経糸地糸接結糸がそれぞれ両側の走行面側経糸に近接することで、走行面側層には比較的大きなろ水空間形成することができろ水性を向上させることができる。その他に経糸地糸接結糸の走行面側ナックルを走行面側経糸の走行面側ナックルに隣接配置したことで、経糸地糸接結糸の糸の移動がなく安定した織物とすることができ、また走行面側経糸よりも線径の小さい経糸地糸接結糸の摩耗を軽減させる効果もある。
また、上面側層では組になった経糸地糸接結糸が交互に上面側表面に現れ、つまりどちらか1本が上面側表面に現れたとき、他の1本は上面側表面の下にあって2本1組で、上面側緯糸と織り合わされて1本の上面側経糸のように機能している。経糸地糸接結糸2においては、経糸地糸接結糸2aが上面側緯糸9’,10’,11’,12’,13’,14’,15’,16’,17’と織り合わされており、15’と織り合わされるところの下側で、経糸地糸接結糸2bが走行面側緯糸と織り合わされており、経糸地糸接結糸2bが上面側緯糸19’,20’,1’,2’,3’,4’,5’,6’,7’と織り合わされるところの下側で、経糸地糸接結糸2aが走行面側緯糸1’と織り合わされている。そして、2本で交互に現れた経糸地糸接結糸2は、走行面側経糸1と走行面側経糸3のほぼ中央の上方で1本の経糸のように機能して、上面側緯糸と織り合わされて平織組織を形成している。
また、経糸地糸接結糸の両側に配置している経糸も、上面側では経糸地糸接結糸と上面側経糸、そして上面側緯糸が織り合わされて上面側表面全体に平織組織を形成する。平織組織は緻密な表面を形成することができるため平滑性に優れ、また均一なろ水空間を確保できる。
緯方向には上面側緯糸、走行面側緯糸が上下同じ本数で配置されているが、その他の配置割合としてもよく、走行面側層は織物の走行によって生じる摩耗に耐え得る緯糸摩耗型組織としている。走行面側緯糸1’では1本の走行面側経糸1と経糸地糸接結糸2aの上側を通った後、4本の走行面側経糸3,5,7,9の下側を通り、次いで1本の走行面側経糸11と経糸地糸接結糸12aの上側を通り、4本の走行面側経糸13,15,17,19の下側を通る走行面側緯糸が走行面側経糸4本分のロングナックルを形成する組織とした。
ここでは、上面側経糸1,走行面側経糸1,経糸地糸接結糸2,走行面側緯糸1’を例にあげて説明したが、その他の構成糸も同様の組織とすることで、表面平滑性、接結力に優れ、均一なろ水性を有する工業用多層織物を提供することができる。
図3は本発明の実施例である図2の多層織物の緯糸15’に沿った断面図であり、図4は緯糸1’に沿った断面図である。またそれぞれの経方向の糸の位置関係をわかりやすく説明するために適宜経糸に沿ってI,II,IIIの線を示した。Iは経糸1の中心を通る直線であり、IIは経糸1と経糸3のほぼ中央を通る直線であり、IIIは経糸3の中心を通る直線である。
図3と図4からわかるように経糸地糸接結糸は経糸間に2本1組で配置されており、一方の経糸地糸接結糸が上面側表面を形成しているところの下側で、もう一方の経糸地糸接結糸が走行面側緯糸と織り合わされている。また、経糸間に配置している経糸地糸接結糸は走行面側緯糸によって隣接配置している走行面側経糸と一緒に織り込まれ、組を形成する2本の経糸地糸接結糸のうち、図2の意匠図上の左側の経糸地糸接結糸は左側の走行面側経糸1に近接配置し、図3の意匠図の右側の経糸地糸接結糸は右側の走行面側経糸に近接配置している。そして上面側表面では組を形成する2本の経糸地糸接結糸が上面側表面に交互に現れて、互いに接近して走行面側経糸のほぼ中央の上方で実質経糸1本分の組織を形成していることがわかる。
経糸地糸接結糸2を例にして説明すると、組になった経糸地糸接結糸2aと経糸地糸接結糸2bは、経糸1と経糸3の間に2本1組になって配置しており、経糸地糸接結糸2aが上面側層を形成しているところの下側で、経糸地糸接結糸2bが走行面側層を織り合わせている。図4ではその逆で、経糸地糸接結糸2bが上面側層を形成しているところの下側で、経糸地糸接結糸2aが走行面側層を織り合わせている。このように組になった経糸地糸接結糸は、上面側表面に交互に現れて上面側緯糸と織り合わされて1本の経糸のように機能している。
走行面側層では組を形成する2本の経糸地糸接結糸2aと2bのうち、図2の意匠図に示されている左側の経糸地糸接結糸2aを左側の走行面側経糸1に近接配置したことが図4からわかる。また、図2の意匠図に示されている右側の経糸地糸接結糸2bが右側の走行面側経糸3に近接配置したことが図3からわかる。このような構造としたことで走行面側経糸1と走行面側経糸3の間に比較的大きなろ水空間が形成される。
また、上面側表面では組を形成する2本の経糸地糸接結糸が、互いに接近して走行面側経糸のほぼ中央の上方で実質経糸1本分の組織を形成していることがわかる。図3と図4にはそれぞれの経方向の糸の位置関係をわかりやすく説明するためにI,II,III線を断面図上に示しているが、上面側層では経糸1と経糸3のほぼ中央を通る直線II上に、図3の経糸地糸接結糸2aと、図4の経糸地糸接結糸2bが配置されている。図3、図4から経糸地糸接結糸が上面側に現れるところでは走行面側経糸の中央の上方に位置していることがわかり、また互いに接近して実質経糸1本分の組織を形成していることも明らかである。そのため、上面側表面には上面側経糸1、2aと2bからなる経糸地糸接結糸2,上面側経糸3が等間隔で配置されおり、均一なろ水空間が形成されている。ここでは経糸1,経糸地糸接結糸2,経糸3を例にあげて説明したが、その他の構成糸に関しても同様であり、表面性、接結力に優れ、均一なろ水性を有する多層織物を形成することができる。

BACKGROUND OF THE INVENTION
The present invention relates to industrial fabrics such as papermaking fabrics, conveyor belts, filter fabrics and the like.
[0002]
[Prior art]
Conventionally, fabrics woven with warps and wefts have been widely used as industrial fabrics. For example, they are used in many other fields, such as papermaking wires, conveyor belts, and filter fabrics. Woven properties are required. In particular, the demands for papermaking wires used in the papermaking process that uses the mesh of the fabric to dehydrate the raw materials are severe, and the fabric has excellent surface properties that do not transfer the fabric wire mark to the paper. Therefore, there is a demand for a fabric that has sufficient rigidity to be suitably used even in a harsh environment, and that can maintain the conditions necessary for producing good paper for a long period of time. In addition, fiber support, improvement in papermaking yield, good freeness, wear resistance, dimensional stability, running stability, and the like are required. In recent years, the speed of papermaking machines has increased, and the demand for papermaking wires has become more severe.
As described above, the papermaking fabrics, which are particularly demanding of industrial fabrics, can be understood to understand the requirements and solutions of most industrial fabrics. Therefore, the present invention will be described below on behalf of papermaking fabrics.
For example, when the paper making speed is increased, the dewatering speed is inevitably increased, and it is necessary to increase the dewatering power. Naturally, the loss of fibers, fillers, etc. and the occurrence of wire marks become prominent, and further improvements in fiber support and surface properties are required. In addition, when the wet paper is deepened into the papermaking fabric or when the fiber is pushed in, the wet paper releasability when the wet paper is transferred to the felt also deteriorates. The wet paper formed on the fabric is pressed against the surface of the fabric by the dehydration force, so the yarn is difficult to wet in the area where the yarn is present, and conversely, the wet paper is between the mesh where there is no yarn. This is because a thread and a mesh mark are generated on the surface of the wet paper. Although it is impossible to eliminate the wire mark completely, in order to make it less noticeable as much as possible, the surface of the upper layer of the fabric must be made fine to improve surface smoothness and fiber support. However, fine woven fabrics that emphasize surface properties and fiber support are basically inferior in wear resistance because they are woven with yarns having a small wire diameter.
In addition, since the papermaking fabric travels at a high speed, there is a phenomenon in which the fabric gradually wears due to friction with a roll or the like on the traveling surface side that comes into contact with the machine, and the wear may end its life. In order to improve the wear resistance, various measures are required such as changing the fabric structure to a weft-worn type structure or changing the material of the thread. In particular, the use of a thread with a large wire diameter provides wear resistance. This method is generally used. However, although the yarn having a large wire diameter has improved wear resistance, it has been difficult to obtain excellent surface properties.
In order to solve both the surface property and the abrasion resistance problem, two fabrics composed of different warps and wefts are used for the upper surface side layer and the traveling surface side layer, and the fabrics of both layers are connected. Two-layer fabrics integrated by tying have been used. This method has an effect that a fabric according to the performance required for each method can be adopted. A dense upper layer surface was formed using warps and wefts having a small wire diameter on the upper surface side layer, and a running surface having high wear resistance was formed using warps and wefts having a large wire diameter on the traveling surface side layer. In order to prevent the surface property from being deteriorated, generally, a yarn having a diameter smaller than that of the upper surface side warp and the upper surface side weft is used for the binding yarn. In order to form a dense surface, a plain weave is often used for the upper surface side layer structure. However, since the binding yarn is actually used to interweave the two layers, the binding yarn is substantially attached to the surface of the plain weave. Surfaces arranged in places will be formed. Since the binding yarn has a portion that appears on the surface in this way, it is not preferable to use a yarn having a very large wire diameter because of surface smoothness.
In addition, normal paper fabrics are often tensioned in the warp direction during use, and the warp yarns are always in tension. In the case of binding yarns that are often placed between wefts due to problems such as weaving and fiber support properties, the yarn is stretched when tension is applied, and the binding yarn is entangled between the upper surface side layer and the running surface side layer. There was a problem that abrasion occurred and a gap was generated or separated between fabrics. This is because the endless belt is running while being laid on several rolls. At the part where the fabric comes into contact with the roll, the two-layer fabric is curved along the arc of the roll, and there is a difference in circumferential length between the layers of the fabric. Because it occurs. As a result, the binding yarns interweaving the layers are squeezed and internal wear occurs. Internal wear is often seen in binding yarns with small wire diameter and low strength used to improve surface properties. The binding force of the upper surface side layer and the running surface side layer with only a binding yarn having a small wire diameter was insufficient. In addition, the binding yarn is entangled with the yarn on the upper surface side layer to connect the two fabrics, and the surface property of the fabric is deteriorated by giving a dent to the surface on the upper surface side to draw the yarn by the binding force. There was also.
Accordingly, development of multilayer fabrics using warp binding yarns that weave the upper surface side layer and the running surface side layer while forming the upper surface side surface on the warp yarn has been carried out. In the upper surface side layer, a warp base yarn that forms a pair with the upper surface side warp was used as the warp forming the upper surface, and the upper surface was formed by weaving with the upper surface weft. The running surface side layer was formed by running surface side warps and running surface side wefts. Furthermore, for the purpose of improving the binding force and making the mesh uniform, fabrics and the like have been developed in which all of the warp forming the upper surface layer is a warp binding yarn. However, a multilayer fabric woven with conventional warp binding yarns has a structure in which a pair of warp binding yarns is arranged next to one running surface side warp. Since one set of warp binding yarns is always arranged adjacent to the same traveling surface side warp, two warp binding yarns are biased to the side of one traveling surface side warp in the traveling surface side layer. Arranged. Similarly, since the two warp binding yarns forming a pair also on the upper surface side layer are arranged in the same manner as the traveling surface side layer, the uniformity of the drainage space cannot be ensured and uniform dewatering is performed. There was a problem that I could not.
[0003]
[Problems to be solved by the invention]
In view of the above problems, the present invention is a set of two warp yarn binding yarns that are interwoven with upper surface side wefts to form a part of the upper surface side surface and connect the upper surface side layer and the running surface side layer. Place two warp binding yarns that form a pair on the running surface side close to the adjacent traveling surface side warp yarns on both sides, and alternate two warp binding yarns that form a pair on the upper surface side Appearing on the upper surface side surface and forming a structure corresponding to one warp substantially above the center between the running surface side warps to make the woven fabric uniform and free from contact. An object of the present invention is to provide an industrial multilayer fabric excellent in binding strength and surface smoothness.

DETAILED DESCRIPTION OF THE INVENTION
The industrial fabric of the present invention is used as an industrial fabric such as a papermaking wire, a conveyor belt, and a filter cloth, and can be suitably used as a papermaking wire that is particularly demanding by users.
The present invention is an industrial multilayer fabric comprising at least an upper surface side layer and a traveling surface side layer, and connecting the upper surface side layer and the traveling surface side layer by warp binding yarns forming a part of the upper surface side layer. A part or all of the upper surface side warp was used as the warp binding yarn. Two warp binding yarns are arranged in pairs in the running direction of the woven fabric, and the upper surface is formed with the upper surface side warp or with the warp base yarn binding yarn alone, and the two warp ground binding yarns are formed. When one of them is on the upper surface side surface, the other yarn is present on the lower side of the upper surface side layer and appears alternately on the upper surface surface to form a structure corresponding to one upper surface side warp. Woven with the upper surface side weft to form part of the upper surface. Of the two warp ground yarn binding yarns that form a pair in the traveling surface side layer, one warp ground yarn binding yarn is close to the traveling surface side warp that is closer to that yarn and the other warp ground yarn binding The yarn is close to the running surface side warp which is closer to the yarn and separated from each other. On the upper surface side, the two warp ground yarn binding yarns forming a pair approach each other and are approximately in the middle between the running surface side warps. A structure is formed so as to form a structure corresponding to one upper surface side warp on the upper side. This multi-layered fabric uses warp binding yarns arranged in the warp direction for the binding yarns connecting the two layers, so that the binding force is strong, and the warp ground binding yarns have two layers. Excellent surface smoothness because part of the upper surface side layer is formed while being bound, and two warp ground yarn binding yarns that form a pair on the upper surface are the upper part of the center between the running surface side warps. In order to form a structure equivalent to one warp, a uniform mesh space is given to the entire surface of the fabric, and the freeness becomes uniform.
[0006]
The most advantageous effect of arranging warp ground yarn binding yarns that weave two layers in the fabric running direction as in the present invention is the conventional binding yarn that does not contribute to the formation of the surface structure. In contrast, since the warp binding yarn functions as a part of the fabric surface, there is no occurrence of local dents. In addition, warp binding yarns are used in a warp direction, that is, generally in the direction of running of the fabric and are always under tension, so there is no occurrence of slack in the yarn, and even when viewed from the fabric structure. Tend to be strong.
Then, two warp binding yarns are arranged between the warp yarns, and one warp binding yarn of the two warp binding yarns forming the pair in the running surface side layer is the yarn. It is arranged adjacent to the running surface side warp closer to the other side, and the other warp ground yarn binding yarn is arranged adjacent to the running surface side warp closer to the yarn so that it forms a pair in the running surface side layer. The warp binding yarns are spaced apart, thereby ensuring a relatively large drainage space. In the upper surface side layer, a structure corresponding to one substantial upper surface side warp is formed approximately above the center between the two traveling surface side warps. That is, since all the warp direction yarns forming the upper surface side layer are arranged at equal intervals, a uniform drainage space is arranged in the upper surface side layer.
Further, it is preferable that the traveling surface side warp passes under the traveling surface side weft, and one warp ground yarn binding yarn adjacent thereto passes under the same traveling surface side weft. In other words, the left warp base yarn binding yarn of the set of two warp base yarn binding yarns is such that the running surface side warp arranged on the left side passes under the traveling surface side wefts. A structure in which the ground yarn binding yarn passes under the same running surface side weft, and the right warp ground yarn binding yarn of the two sets of warp ground yarn binding yarns is disposed on the right side thereof. Where the surface side warp passes below the traveling surface side weft, the warp ground yarn binding yarn passes below the same traveling surface side weft. With such a structure, each warp ground yarn binding yarn is arranged close to the traveling surface side warp on both sides, so that the two warp ground yarn binding yarns are arranged apart from each other on the traveling surface side layer. A relatively large drainage space can be formed in the running surface side layer. In addition, there is an effect that it is possible to reduce the wear of the warp ground yarn binding yarn that is generally smaller in diameter than the running surface side warp.
[0007]
There are a method of using both the upper surface side warp and the warp yarn binding yarn as the warp forming the upper surface side layer, and a method of using only the warp yarn binding yarn. The structure of each of the upper surface side warp, warp binding yarn, running surface side warp, etc. constituting the woven fabric is not particularly limited, but the upper surface side layer may have a structure that hardly gives the woven fabric mark to the wet paper. Desirably, the running surface side layer preferably has a structure resistant to abrasion caused by running of the fabric. On the running surface side, the running surface side warp may be arranged in the running surface side layer, and the warp base yarn binding yarns in pairs may be arranged therebetween.
The structures of the warp binding yarns that are paired may be the same or different. As an example using warp binding yarns of different textures, six upper knuckles are formed on the upper surface by passing alternately one upper surface side weft and one lower surface side weft, and then 5 A warp ground yarn binding yarn of a structure that passes under the upper surface side weft of the book, then passes under the one running surface side weft, and then passes under the upper surface side of the seven upper side wefts; Some warp binding yarns are formed by combining two textures opposite in the traveling direction. This reverse structure is just because the adjacent traveling surface side warp and warp binding yarn are adjacent to each other and pass under the same traveling surface side weft. Absent. Preferably, as in this example, one traveling surface side weft interweaves both the traveling surface side warp and the warp ground yarn binding yarn, that is, the adjacent traveling surface side warp and warp ground yarn binding yarn are A structure that passes adjacently under the same running surface side weft can secure drainage space in the running surface side layer, ensure the stability of the warp binding yarn, and also serve as a wear countermeasure.
This structure was formed by combining two warp binding yarns and forming a plain weave on the upper surface. If the surface of the woven fabric has a plain woven structure, the number of fiber support points increases, so that the fiber support property is improved, and the texture becomes fine, so that the surface smoothness is excellent. The warp binding yarns that form the upper surface side layer in this way preferably have a structure that does not give a mark to the paper by one set of two. In the case of a structure in which the warp binding yarns are different from each other, they may be arranged in combination in the left and right directions for each set. This is because an oblique mark appearing on the surface of the fabric can be broken, and is suitable for a papermaking fabric or the like that places importance on the surface property of the fabric.
The structure of the running surface side warp is not particularly limited, and may be appropriately determined depending on the combination with the warp binding yarn.
[0008]
In addition, the yarn used in the present invention may be selected depending on the use or the function of each yarn on the fabric. For example, in addition to monofilament, multifilament, spun yarn, crimp processing, bulk processing, etc. Furthermore, processed yarns called textured yarns, bulky yarns, stretch yarns, or yarns obtained by combining them together can be used. Also, the cross-sectional shape of the yarn is not limited to a circle, but a short yarn such as a square shape or a star shape, an elliptical shape, or a hollow yarn can be used. In addition, the material of the yarn can be freely selected, and polyester, nylon, polyphenylene sulfide, polyvinylidene fluoride, polypro, aramid, polyetheretherketone, polyethylene naphthalate, polytetrafluoroethylene, cotton, wool, metal, etc. are used. it can. Of course, you may use the thread | yarn which blended and contained various substances according to the objective to these copolymers or these materials.
[0009]
As a papermaking wire, it is generally preferable to use a polyester monofilament having rigidity and excellent dimensional stability for the upper surface side warp, the running surface side warp, and the upper surface side weft. Further, as the warp binding yarn, it is preferable to use a polyester monofilament like the upper side warp. The types and wire diameters of the upper surface side warp and warp binding yarn may be the same or different, and can be selected as needed from the nature of the fabric, weaving properties, and the like. However, the roles of upper side warp and warp ground yarn binding thread are different, and warp ground yarn binding is often arranged between two warps as a pair. Is preferred.
In addition, it is preferable to interweave polyester monofilaments and nylon monofilaments on the running surface side wefts that require abrasion resistance, for example, because the abrasion resistance can be improved while securing rigidity. Each wire diameter may be selected in accordance with the application and appropriate. Generally, it is preferable to use a relatively small diameter yarn for the upper surface side warp and the upper surface side weft to form the upper surface side layer. It is preferable to use a relatively large diameter yarn for the running surface side warp and the running surface side weft forming the side layer. In addition, the warp ground yarn binding yarn that weaves the upper surface side layer and the running surface side layer while forming the upper surface side surface with one set of two pieces is arranged in a single pair, so it has a smaller diameter than the upper surface side warp yarn. Some are preferable, but may be appropriately changed in accordance with the intended use and the desired physical properties.

[0011]
Example 1
In the design diagram of FIG. 1, this example is a two-layer fabric composed of warp binding yarn, upper surface side warp, upper surface side weft, running surface side warp, and running surface side weft. An upper surface side warp and a warp ground yarn binding yarn are arranged on the warp forming the upper surface side layer, and a pair of warp ground yarn binding yarns arranged between the warps are used as an upper layer and a lower layer.
The layers are interwoven.
In the embodiment of FIG. 1, a set of two warp binding yarns are arranged between the warps, and when one of these appears on the upper surface, the other is below the upper surface. In this way, the upper surface side weft and the weave-free upper surface side surface were formed with a structure equivalent to one warp. A set of two warp ground yarn binding yarns forms a plain weave structure substantially equivalent to one warp through the upper and lower sides of one upper surface side weft. Of the two warp binding yarns that form a pair on the running surface side, the warp binding yarn (the yarn with a) placed on the left side of the design drawing is placed on the left side. The other warp binding yarn (yarn marked with b) is arranged close to the warp arranged on the right side. This is because the warp ground yarn binding yarn is woven by one traveling surface side weft together with the traveling surface side warp, and the warp ground yarn binding yarn having a smaller diameter than the traveling surface side warp is the traveling surface side warp. It will move to the side and will be placed closer.
That is, the warp ground yarn binding yarns that are paired are arranged apart from each other on the traveling surface side layer, so that a relatively large drainage space is formed between them, and the fabric is excellent in drainage.
Further, in the upper surface side layer, the two warp ground yarn binding yarns forming a pair approach each other and are positioned almost above the center between the running surface side warp yarns, and are interwoven with the upper surface side weft yarns to obtain one substantial warp yarn. Form a plain weave structure of the minute. Since the warp binding yarns in a pair are one side forming the upper surface side layer, the other passes through the lower side of the running surface side weft, and the two layers are woven together, Two are not simultaneously arranged adjacent to the upper surface side layer but appear alternately on the upper surface side surface. As a result, when the yarn arranged on the left side of the design diagram among the warp base yarn binding yarns forming a pair forms an upper surface side layer, the other warp base yarn binding yarns forming the pair are Since it does not appear in the upper surface side layer, a force that moves to the right side on the design drawing works. On the other hand, the warp binding yarn arranged on the right side has the other warp binding yarn binding yarn in the pair not appearing in the upper surface side layer, so that a force to move to the left side on the design drawing works. As a result, the two warp binding yarns act in a direction facing each other, and form a structure like a single upper surface side warp on the upper surface side at the approximate center between the warp yarns. Further, since the upper surface side warp also forms a plain weave structure, the upper surface side surface is formed of a pair of warp ground yarn binding yarn, upper surface side warp and upper surface side weft. In addition, since the warp binding yarn has the above structure, a uniform drainage space is formed between the warps forming the upper surface.
FIG. 1 shows an embodiment of the present invention, in which two warp yarns are arranged in a pair of warp yarns with different structures and are formed in the running surface side layer. The binding yarns are arranged close to the running surface side warps adjacent to each other, and in the upper surface side layer, one warp ground yarn binding yarn appears on the upper surface side substantially above the center between the two traveling surface side warps. The other is below the upper surface and forms a structure of one substantial warp.
The warp binding yarn is one upper surface side weft On the top of the thread Passing the lower side alternately, forming 6 knuckles on the upper surface, 5 Min Upper side weft of And running surface side weft Then pass under one weft on the running surface side, then 7 Min Upper side weft of And running surface side weft Is formed by combining two warp ground yarn binding yarns having a structure passing through and a structure in which the warp ground yarn binding yarns are opposite in the traveling direction. Specifically, taking the warp yarn binding yarn 2 as an example, the warp yarn binding yarn 2a passes under one traveling surface side weft 1 'and then seven upper surface side wefts 2', 3 ', 4', 5 ', 6', 7 ', 8' and running surface side latitude Of yarn And then passes through the upper side of one upper surface side weft 9 'to form a knuckle on the upper surface side surface, and passes between one upper surface side weft 10' and the traveling surface side weft 10 '. A knuckle is formed on the upper surface through the upper side of the upper surface side weft 11 ′, passes between the upper surface side weft 12 ′ and the traveling surface side weft 12 ′, and passes the upper side of the upper surface side weft 13 ′. A knuckle is formed on the surface on the upper surface side, passes through between the upper surface side weft 14 'and the traveling surface side weft 14', passes the upper side of the upper surface side weft 15 ', and knuckles on the upper surface side surface. Formed, passes between one upper surface side weft 16 ′ and the traveling surface side weft 16 ′, passes the upper side of one upper surface side weft 17 ′, forms a knuckle on the upper surface, and forms one upper surface side. A knuckle is formed on the surface on the upper surface side through the upper side of one upper surface side weft yarn 19 ′, passing between the weft yarn 18 ′ and the running surface side weft yarn 18 ′, and then 5 Upper surface side wefts 20 ', 21', 22 ', 23', 24 'and running surface side wefts Of yarn It is an organization that passes between them. Pair with it One The warp base yarn binding yarn 2b passes through the upper side of one upper surface side weft 1 'to form a knuckle on the upper surface side surface, and one upper surface side weft 2' and running surface side weft
Passing between the yarns 2 ', passing through the upper side of one upper surface side weft 3', forming a knuckle on the upper surface side surface, passing between one upper surface side weft 4 'and the running surface side weft 4', A knuckle is formed on the upper surface through the upper surface of one upper surface weft 5 ', passes between one upper surface weft 6' and the running surface weft 6 ', and one upper surface weft 7'. The knuckle is formed on the upper surface side through the upper side of the upper surface, and the seven upper surface side wefts 8 ', 9', 10 ', 11', 12 ', 13', 14 'and the running surface side weft Of yarn And then the lower side of one running surface side weft 15 'and five upper surface side wefts 16', 17 ', 18', 19 ', 20' and the running surface side weft Of yarn The knuckle is formed on the upper surface through the upper side of the one upper surface side weft 21 ', and then passes between the upper surface side weft 22' and the traveling surface side weft 22 '. This is a structure in which a knuckle is formed on the upper surface side surface through the upper side of the upper surface side weft 23 ′ and then passes between one upper surface side weft 24 ′ and the running surface side weft 24 ′. In this pair of warp binding yarns 2a and 2b, the structure is reversed when viewed in the traveling direction, that is, in the vertical direction of the design drawing.
Although these two warp ground yarn binding yarns 2a and 2b are arranged between the two warp yarns 1 and 3 in parallel on the design drawing, the warp ground yarn binding is actually performed on the running surface side layer. Since the binding yarn 2a is woven by the traveling surface side weft 1 'together with the traveling surface side warp 1, the warp ground yarn binding yarn 2a having a smaller diameter than the traveling surface side warp 1 moves to the traveling surface warp 1 side. Since the warp ground yarn binding yarn 2b is woven together with the traveling surface side warp 3 by the traveling surface side weft 1, it has a smaller diameter than the traveling surface side warp 3. The warp base yarn binding yarn 2b moves to the traveling surface warp 3 side and is disposed close to the traveling surface side warp 3. This is because the traveling surface side warp passes under the traveling surface side weft and the warp ground yarn binding yarn adjacent to the traveling surface side weft passes under the same traveling surface side weft. The pair of warp ground yarn binding yarns is close to the traveling surface side warp on both sides, so that a relatively large drainage space can be formed in the traveling surface side layer, and the freeness can be improved. . In addition, the running surface side knuckle of the warp ground yarn binding yarn is arranged adjacent to the traveling surface side knuckle of the traveling surface side warp, so that the warp ground yarn binding yarn does not move and a stable fabric can be obtained. Also, there is an effect of reducing the wear of the warp binding yarn having a smaller wire diameter than the running surface side warp.
In the upper surface side layer, a pair of warp ground yarn binding yarns appear alternately on the upper surface side surface, interweave with the upper surface side wefts and function as one warp. In the warp ground yarn binding yarn 2, The warp binding yarn 2a is interwoven with upper surface side wefts 9 ', 10', 11 ', 12', 13 ', 14', 15 ', 16', 17 ', 18', 19 '. On the lower side, the warp base yarn binding yarn 2b passes below the running surface side weft 15 'and weaves the upper layer and the lower layer. Further, the warp binding yarn 2b is interwoven with the upper surface side wefts 21 ', 22', 23 ', 24', 1 ', 2', 3 ', 4', 5 ', 6', 7 '. On the lower side, the warp binding yarn 2a passes under the running surface side weft 1 'and weaves the upper layer and the lower layer. The warp base yarn binding yarn 2a and the warp base yarn binding yarn 2b function like a single warp above the approximate center of the running surface side warp 1 and the running surface side warp 3, and the upper surface side. It is interwoven with wefts to form a plain weave structure. This is because, when one warp ground yarn binding yarn forms the upper surface side layer, the other warp ground yarn binding yarn appears on the upper surface side layer. Rather, the two warp binding yarns alternately form the upper surface side surface, so that force acts in the direction facing each other, and functions as one upper surface side warp at the approximate center between the warp yarns.
In addition, the warp yarns arranged on both sides of the warp binding yarn are also interwoven with the warp binding yarn, the upper surface side warp, and the upper surface side weft on the upper surface side to form a plain weave structure on the entire upper surface. . Since the plain weave structure can form a dense surface, it has excellent smoothness and can secure a uniform drainage space.
In the weft direction, the upper surface side wefts and the running surface side wefts are arranged in the same number up and down, but other arrangement ratios are possible, and the running surface side layer is a weft wear type structure that can withstand the wear caused by running of the fabric. Yes. In the running surface side weft 1 ', after passing through the upper side of one running surface side warp 1 and warp ground yarn binding yarn 2a, five running surface side warps 3, 5, 7, 9, 11 that are continuous, The five running surface side warps 15, 17, 19 pass through the lower side of the warp ground yarn binding yarn existing between them, and then the upper side of one running surface side warp yarn 13 and the warp ground yarn binding yarn 14a. , 21, 23, and the time between them
The structure is such that the running surface side wefts form a long knuckle for five running surface side warps through the lower side of the yarn binding yarn.
Here, the upper surface side warp 1, the traveling surface side warp 1, the warp ground yarn binding yarn 2, the traveling surface side weft 1 'have been described as examples, but the other constituent yarns have the same structure, An industrial multilayer fabric having excellent surface smoothness and binding force and having uniform drainage can be provided.
[0012]
Example 2
FIG. 2 shows another embodiment of the present invention, in which two warp binding yarns having different structures are arranged in a pair between warps, and the warp side layer forms a pair. The ground yarn binding yarns are arranged close to the running surface side warps adjacent to each other, and in the upper surface side layer, the warp ground yarn binding yarns that are paired approximately above the center between the two traveling surface side warps are the upper surface side surface. Appear alternately to form a structure of one substantial warp.
The warp binding yarn is one upper surface side weft On the top of the thread 5 knuckle is formed on the upper surface by alternately passing through the lower side, and then 3 Min Upper side weft of And running surface side weft Then pass under one weft on the running surface side, then 7 Min Upper side weft of And running surface side weft Is formed by combining two warp ground yarn binding yarns having a structure passing through and a structure in which the warp ground yarn binding yarns are opposite in the traveling direction. Specifically, taking the warp yarn binding yarn 2 as an example, the warp yarn binding yarn 2a passes under one traveling surface side weft 1 'and then seven upper surface side wefts 2', 3 ', 4', 5 ', 6', 7 ', 8' and running surface side latitude Of yarn And then passes through the upper side of one upper surface side weft 9 'to form a knuckle on the upper surface side surface, and passes between one upper surface side weft 10' and the traveling surface side weft 10 '. A knuckle is formed on the upper surface through the upper side of the upper surface side weft 11 ′, passes between the upper surface side weft 12 ′ and the traveling surface side weft 12 ′, and passes the upper side of the upper surface side weft 13 ′. A knuckle is formed on the surface on the upper surface side, passes through between the upper surface side weft 14 'and the traveling surface side weft 14', passes the upper side of the upper surface side weft 15 ', and knuckles on the upper surface side surface. Formed, passes between one upper surface side weft 16 ′ and the traveling surface side weft 16 ′, passes the upper side of one upper surface side weft 17 ′, forms a knuckle on the upper surface side, and has three upper surface sides. Wefts 18 ', 19', 20 'and running surface side weft Of yarn It is an organization that passes between them. The other warp binding yarn 2b that forms a pair passes through the upper side of one upper surface side weft 1 'to form a knuckle on the upper surface side, and one upper surface side weft 2' and running surface side weft 2 ′, passing through the upper side of one upper surface side weft 3 ′, forming a knuckle on the upper surface side surface, passing between one upper surface side weft 4 ′ and the traveling surface side weft 4 ′, A knuckle is formed on the upper surface of the upper surface side weft 5 'through the upper surface of the upper surface side weft 5' and passes between the upper surface side weft 6 'and the traveling surface side weft 6'. A knuckle is formed on the upper surface through the upper side, and seven upper wefts 8 ', 9', 10 ', 11', 12 ', 13', 14 'and the running surface side weft Of yarn And then the lower side of one running surface side weft 15 'and three upper surface side wefts 16', 17 ', 18' and the running surface side weft Of yarn This is a structure in which a knuckle is formed on the upper surface side through the upper side of one upper surface side weft 19 ', and then passes between one upper surface side weft 20' and the traveling surface side weft 20 '. The pair of warp yarn binding yarns 2a and 2b is a structure that is opposite in the traveling direction.
These two warp ground yarn binding yarns are arranged between the two warp yarns 1 and 3 in parallel on the design drawing, but the warp ground yarn binding yarns 2a are arranged on the traveling side layer. The running surface side warp 1 is arranged in proximity. Further, the warp base yarn binding yarn 2b is disposed close to the traveling surface side warp yarn 3. This is because the traveling surface side warp passes under the traveling surface side weft and the warp ground yarn binding yarn adjacent to the traveling surface side weft passes under the same traveling surface side weft. When the warp binding yarns in a pair are close to the running surface side warps on both sides, a relatively large drainage space can be formed in the running surface side layer, and the freeness can be improved. In addition, the running surface side knuckle of the warp ground yarn binding yarn is arranged adjacent to the traveling surface side knuckle of the traveling surface side warp, so that the warp ground yarn binding yarn does not move and a stable fabric can be obtained. Also, there is an effect of reducing the wear of the warp binding yarn having a smaller wire diameter than the running surface side warp.
Further, in the upper surface side layer, the warp binding yarns in pairs appear alternately on the upper surface, that is, when one of them appears on the upper surface, the other one is below the upper surface. Thus, a pair of two yarns is interwoven with the upper surface side weft and functions like one upper surface side warp. In the warp base yarn binding yarn 2, the warp base yarn binding yarn 2a is interwoven with the upper surface side weft yarns 9 ', 10', 11 ', 12', 13 ', 14', 15 ', 16', 17 '. The warp yarn binding yarn 2b is woven with the running surface side weft below the portion where the yarn is woven with 15 ', and the warp yarn binding yarn 2b is connected to the upper surface side wefts 19', 20 ', On the lower side where 1 ′, 2 ′, 3 ′, 4 ′, 5 ′, 6 ′ and 7 ′ are woven together, the warp ground yarn binding yarn 2a is woven with the running surface side weft 1 ′. The warp base yarn binding yarn 2 that appears alternately in two pieces functions like a single warp above approximately the center of the running surface side warp 1 and the running surface side warp 3, Interwoven to form a plain weave structure.
In addition, the warp yarns arranged on both sides of the warp binding yarn are also interwoven with the warp binding yarn, the upper surface side warp, and the upper surface side weft on the upper surface side to form a plain weave structure on the entire upper surface. . Since the plain weave structure can form a dense surface, it has excellent smoothness and can secure a uniform drainage space.
In the weft direction, the upper surface side wefts and the running surface side wefts are arranged in the same number up and down, but other arrangement ratios are possible, and the running surface side layer is a weft wear type structure that can withstand the wear caused by running of the fabric. Yes. In the running surface side weft 1 ', after passing through the upper side of one running surface side warp 1 and warp ground yarn binding yarn 2a, it passes under the four running surface side warps 3, 5, 7, 9; Next, the traveling surface side wefts that pass through the upper side of one traveling surface side warp 11 and the warp base yarn binding yarn 12a pass under the four traveling surface side warps 13, 15, 17, 19 are traveling surface side warps. The structure formed four long knuckles.
Here, the upper surface side warp 1, the traveling surface side warp 1, the warp ground yarn binding yarn 2, the traveling surface side weft 1 'have been described as examples, but the other constituent yarns have the same structure, An industrial multilayer fabric having excellent surface smoothness and binding force and having uniform drainage can be provided.
3 is a cross-sectional view taken along the weft 15 'of the multilayer fabric of FIG. 2 which is an embodiment of the present invention, and FIG. 4 is a cross-sectional view taken along the weft 1'. In addition, in order to easily understand the positional relationship of the respective yarns in the warp direction, I, II, and III lines are shown along the warp as appropriate. I is a straight line passing through the center of the warp 1, II is a straight line passing through the approximate center of the warp 1 and the warp 3, and III is a straight line passing through the center of the warp 3.
As can be seen from FIG. 3 and FIG. 4, the warp binding yarns are arranged in pairs between the warp yarns, and the lower side where one warp binding yarn forms the upper surface side surface. Then, the other warp binding yarn is woven with the running surface side weft. Further, the warp ground yarn binding yarn arranged between the warp yarns is woven together with the running surface side warp adjacently arranged by the running surface side weft, and the two warp ground yarn binding yarns forming the pair Among them, the left warp binding yarn on the left side of the design diagram in FIG. 2 is arranged close to the left running surface side warp 1, and the right warp binding yarn on the right side of the design diagram in FIG. 3 is on the right running surface side. Located close to the warp. Then, on the upper surface side surface, two warp ground yarn binding yarns forming a pair appear alternately on the upper surface side surface, approach each other, and form a structure corresponding to one substantial warp above approximately the center of the running surface side warp. It turns out that it forms.
The warp base yarn binding yarn 2 will be described as an example. Two warp base yarn binding yarns 2a and two warp base yarn binding yarns 2b are paired between the warp yarn 1 and the warp yarn 3. The warp ground yarn binding yarn 2b interweaves the running surface side layer below the portion where the warp ground yarn binding yarn 2a forms the upper surface side layer. In FIG. 4, on the contrary, the warp yarn binding yarn 2a weaves the running surface side layer below the side where the warp yarn binding yarn 2b forms the upper surface side layer. The warp base yarn binding yarns thus assembled appear alternately on the upper surface side surface and interweave with the upper surface side wefts to function as a single warp.
Of the two warp ground yarn binding yarns 2a and 2b forming the pair in the running surface side layer, the left warp yarn binding yarn 2a shown in the design diagram of FIG. 2 is used as the left running surface side warp yarn. It can be seen from FIG. Further, it can be seen from FIG. 3 that the right warp binding yarn 2b shown in the design diagram of FIG. 2 is arranged close to the right running surface side warp 3. With such a structure, a relatively large drainage space is formed between the traveling surface side warp 1 and the traveling surface side warp 3.
In addition, it can be seen that the two warp binding yarns forming a pair on the upper surface side surface are close to each other and form a structure equivalent to one warp substantially above the center of the running surface side warp. . 3 and 4 show the I, II and III lines on the cross-sectional view for easy understanding of the positional relationship between the respective warp yarns. The warp yarn binding yarn 2a shown in FIG. 3 and the warp yarn binding yarn 2b shown in FIG. 4 are arranged on a straight line II passing through the center. 3 and 4, it can be seen that where the warp binding yarn appears on the upper surface side, it is located above the center of the running surface side warp and forms a structure corresponding to one substantial warp close to each other. It is also clear that For this reason, on the upper surface side surface, warp base yarn binding yarns 2 and upper surface side warp yarns 3 composed of upper surface side warps 1, 2a and 2b are arranged at equal intervals to form a uniform drainage space. Here, the warp yarn 1, warp binding yarn 2 and warp yarn 3 have been described as examples, but the same applies to other constituent yarns, and is a multilayer fabric having excellent surface properties and binding power, and having uniform freeness. Can be formed.
