- the surface smoothness is caused by the weave of the upper side warp and the weft.
- the fiber diameter of the weft that interweaves the upper surface side warp and the lower surface side warp is increased, a concave mark is generated on the surface of the paper by the knuckle through which the upper surface side warp passes.
- the stiffness of the weft yarn itself which greatly affects the stiffness of the fabric, is lowered, so the product life of the fabric is shortened.
- the weft that weaves the upper and lower warps is worn or cut, the product life of the fabric will be exhausted.
- the upper side fabric is a yarn having an antifouling function such as a fluorine-based resin as a measure against dirt, specifically, an ethylene-tetrafluoroethylene copolymer (hereinafter referred to as “ethylene-tetrafluoroethylene copolymer”). , Etc.), and a lower side fabric comprising a yarn composed of a blend of a fluoropolymer such as polyethylene terephthalate (hereinafter also referred to as “PET”) and other aromatic dicarboxylic acid polymers.

- a technique is known in which the material of the yarn constituting the upper surface side and the lower surface side of the fabric is properly used.
- the weft yarns that are double are used as binding yarns, the weft yarns form a knuckle on the upper surface side, and therefore the yarns formed by PET or the like having no antifouling effect are It will be exposed to the surface, and the antifouling effect due to the construction of the upper surface side fabric by the fluorine-based resin cannot be obtained sufficiently.
- An object of the present invention is to improve surface smoothness by suppressing knuckles on the surface of a fabric by wefts. Another object of the present invention is to improve the rigidity, wear resistance, and air permeability of a warp double weft single weave fabric. Another object of the present invention is to control the on-stack structure of the upper surface side warp and the lower surface side warp. Furthermore, when the yarn exposed on the upper surface side is formed of a yarn having antifouling function such as fluororesin, the product life is prolonged without reducing the strength of weaving the upper surface side and the lower surface side, and the upper surface side is protected. The purpose is to improve the fouling effect.

Abstract
Description
ここで織物の特性の一つである剛性は、原料や浮遊成分等の目的物を保持、搬送する為に必要である。特に建材の製造工程、フィルタ用途等で重い原料や浮遊成分を取り扱うときには織物の必須特性として過酷な環境下でも好適に使用できる程度の剛性が要求される。寸法安定性は常に安定して織物を走行させる為に必要である。そして防汚性は、紙、不織布又は建材を常に安定した品質の製品として供給する為、又、効率の良いろ過、搬送を行うためにも重要な特性である。
更に、不織布に織物のワイヤーマークが転写しにくい表面平滑性に優れた織物、耐摩耗性を持ち合わせたもの、そして良好な不織布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、不織布の歩留まりの向上、走行安定性等が要求されている。さらに近年では製造マシンが高速化しているため、それに伴い搬送用織物への要求も一段と厳しいものとなっている。
このような不織布用二層織物において、二重となっている緯糸を接結糸とすると、緯糸が上面側でナックルを形成するため、防汚効果のないPET等によって形成された糸が織物の表面に露出することになり、上面側織物をフッ素系樹脂で構成したことによる防汚効果が十分に得られないことになる。
このような問題点を解決するために、緯糸の本数を単に減らすと、織物の剛性が低下することになる。そのため、経糸密度を上げながら織物表面への経糸によるナックルの数を増やすことにより、表面性を向上させる技術が必要とされていた。
(1)少なくとも上面側経糸と下面側経糸が上下に積層し、それらを複数の緯糸によって織り合わせてなる経糸二重緯糸一重織による工業用織物において、隣接する前記緯糸の間に前記上面側経糸と下面側経糸と織り合うことなく常に上面側経糸と下面側経糸の間に配置される補助緯糸が配置されていることを特徴とする経糸二重緯糸一重織による工業用織物である。
(2)前記緯糸の上方に上面側経糸とのみ織り合う上面側浮糸が配置されていることを特徴とする上記(1)に記載された経糸二重緯糸一重織による工業用織物。
(3)前記緯糸の下方に下面側経糸とのみ織り合う下面側浮糸が配置されていることを特徴とする上記(1)又は(2)に記載された経糸二重緯糸一重織による工業用織物である。
(5)前記上面側経糸と上面側浮糸をフッ素樹脂により形成し、前記緯糸をフッ素樹脂以外の糸で形成したことを特徴とする上記(2)乃至(4)のいずれか一に記載された経糸二重緯糸一重織による工業用織物である。
(6)前記上面側浮糸及び\又は下面側浮糸と緯糸との配置比率が、1:1であることを特徴とする上記(2)乃至(5)のいずれか一に記載された経糸二重緯糸一重織による工業用織物である。
本発明に係る経糸二重緯糸一重織による工業用織物は、上面側経糸と下面側経糸が上下に積層させ、当該上下の経糸を複数の緯糸によって織り合わせてなることを特徴とする。このように経糸二重緯糸一重織を工業用織物の基本構造として採用することによって、経糸密度を上げることが可能となる。そのため、織物表面に表れるナックルを上面側経糸によって形成し、またかかるナックルの数を増やすことで表面平滑性を大幅に向上させることができる。
また本発明に係る工業用織物は、隣接する前記緯糸の間に補助緯糸が配置されている。かかる補助緯糸は、前記上面側経糸と下面側経糸と織り合うことなく常に上面側経糸と下面側経糸の間に配置される点に特徴を有する。本発明は、経糸二重緯糸一重織を基本構造として採用し、表面平滑性を向上させるものであるが、剛性が弱まるという問題が生じた。かかる問題点を解決するために隣接する緯糸の間に上面側経糸と下面側経糸と織り合わない特殊な補助緯糸を配置している。かかる補助緯糸により従来の緯糸二重織の織物と同じ剛性を得る事が可能となる。表面平滑性については従来の織物より優れていることは前述のとおりである。
また本発明に係る工業用織物は、前記緯糸の下方に下面側経糸とのみ織り合う下面側浮糸を配置しても良い。かかる浮糸を上面側経糸及び\又は下面側経糸と接触させることによって、経糸の移動を制御し、上下経糸が重なる位置を調整することができ、上下経糸のオンスタック構造を制御することが可能となった。
また本発明に係る工業用織物は、前記補助緯糸の線径を前記緯糸の線径よりも大きくすることが好ましい。補助緯糸の線径を大きくすることによって、経糸の表面露出度が大幅に向上する。又、線径の大きな補助緯糸を使用することによって、織物の剛性を大幅に向上させることできる。又、線径の大きな補助緯糸を使用することによって、上面側浮糸を使用しない場合であっても、緯糸を内部接結とすることができる。更に線径の大きな補助緯糸を使用することによって、上下経糸の移動を制御し、オンスタック構造を制御することが可能となった。
このような構造を採用することによって、防汚性に優れたフッ素系樹脂で表面側に表れる糸を形成することができるため、防汚性の効果を十分に得ることができる。また、比較的高価格であるフッ素系樹脂による横方向の糸の本数を減らすことができるため、製造コストを低廉化することができる。
また、このような構造を採用し、接結機能を有する緯糸をフッ素系樹脂等よりも強度の高いPET等の糸で形成することができる。緯糸を接結糸とすることによって、接結糸が表面に露出しない内部接結を採用することができる。すなわち、フッ素系樹脂等のみで形成された上面側織物の表面に、PET等の糸が露出することを防止することができるという効果が得られる。
本発明に係る工業用織物の上面側経糸及び上面側浮糸を形成するフッ素系樹脂としては、防汚性の高いフッ素を含有する複合樹脂であれば良いが、例えば、ポリテトラフロロエチレン樹脂(PTFE)、テトラフロロエチレン-ヘキサフロロプロピレン共重合体(FEP)、テトラフロロエチレン-パーフロロビニルエーテル共重合体(PFA)、ポリフッ化ビニリデン(PVDF)、エチレン-テトラフロロエチレン共重合体(ETFE)、エチレン-クロロトリフロロエチレン共重合体(ECTFE)から選ばれる少なくとも一つであることが好ましい。特にETFEが防汚性、コストの面から適している。
なお、フッ素樹脂原料(水分散液)中にシリコン樹脂を含ませておくと柔軟性の面で更に好ましい。又、フッ素樹脂原料(水分散液)中に各種顔料を添加しておくと、織物表面の色を任意に変えることができる。
実施形態1
図1は、本発明の実施形態1に係る完全組織を示す平面概念図である。実施形態1に係る工業用織物は不織布用織物である。ここで完全組織とは、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。意匠図において、経糸はアラビア数字である1及び2で示し、緯糸はダッシュを付したアラビア数字である1’~4’で示し、Uは上面側織物の糸であることを示し、Lは下面側織物の糸であることを示す。又、接結糸として機能する緯糸はWを加えることで、例えば2’W等で示す。更に、補助緯糸はSで、浮糸はfで示す。
又、×印は上面側経糸が緯糸の上側に位置し織物表面にナックルを形成していることを示し、○印は下面側経糸が緯糸の下側に位置していることを示し、■印は上面側浮糸が上面側経糸の上側に位置し織物表面にナックルを形成していることを示し、□印は下面側浮糸が下面側経糸の下側に位置していることを示す。
上面側と下面側の経糸は上下に重なって配置され、オンスタック構造を形成している。
隣接する前記緯糸(2’W,4’W)の間には、上面側経糸(1U,2U)と下面側経糸(1L,2L)と織り合うことなく常に上面側経糸と下面側経糸の間に配置される補助緯糸(1’S,3’S)が配置されている。
次に図2(a)に示す如く、本発明に係る経糸二重緯糸一重織による工業用織物は、前記緯糸(2’W,4’W)の上方に上面側経糸(1U)とのみ織り合う上面側浮糸(2’Uf,4’Uf)が配置されている。又、上面側経糸(1U)は、上面側浮糸(2’Uf)の上側を通り、上面側浮糸(4’Uf)の下側を通っている。又、上面側経糸1Uは、緯糸4’Wの下側を通っている。下面側経糸1Lは、2’Wの上側を通っている。更に、前記緯糸(2’W,4’W)の下方に下面側経糸(1L)とのみ織り合う下面側浮糸(2’Lf,4’Lf)が配置されている。
次に図2(b)に示す如く、本発明に係る経糸二重緯糸一重織による不織布用織物は、前記緯糸(2’W,4’W)の上方に上面側経糸(2U)とのみ織り合う上面側浮糸(2’Uf,4’Uf)が配置されている。又、上面側経糸(2U)は、上面側浮糸(2’Uf)の下側を通り、上面側浮糸(4’Uf)の上側を通っている。又、上面側経糸(2U)は、緯糸(2’W)の下側を通っている。下面側経糸(2L)は、緯糸(4’W)の上側を通っている。更に、前記緯糸(2’W,4’W)の下方に下面側経糸(2L)とのみ織り合う下面側浮糸(2’Lf,4’Lf)が配置されている。
更に、前記緯糸(2’W,4’W)の下方に下面側経糸(2L)とのみ織り合う下面側浮糸(2’Lf,4’Lf)が配置されている。
ここで、上面側浮糸及び下面側浮糸と緯糸との配置比率は、1:1となっている。このように上面側浮糸(2’Uf,4’Uf)を緯糸(2’W,4’W)の上に配置することによって、緯糸(2’W、4’W)が織物の表面に表れるという問題を解決することができる。
実施形態1に係る不織布用織物は、上述のような構造を採用することにより、織物表面に表れるナックルを上面側経糸(1U,2U)のみによって形成し、ナックル密度を増やすことができ、表面平滑性を向上させることができる。
