Definitions
- the present invention relates to a woven fabric used for transporting a non-woven fabric.
- a two-layer fabric for non-woven fabric consisting of a front surface layer consisting of front surface side warp threads and front surface side weft threads and a back surface layer consisting of back surface side warp threads and back surface side weft threads.
- the first warp pair in which the front side tie warp that functions as a knot and the back side tie warp that functions as a tie is arranged in a substantially vertical direction, and the front side warp and the back side warp are vertically arranged.
- a two-layer fabric for a non-woven fabric has been devised, which comprises a second pair of warp threads arranged in layers and a third pair of warp threads in which two surface-side warp threads are juxtaposed adjacent to each other (see Patent Document 1).
- the present invention has been made in view of such a situation, and one of its exemplary purposes is to provide a new technique for further improving the grip of a belt suitable for transporting a non-woven fabric.
- the nonwoven fabric of a certain aspect of the present invention is a rubber resin classified into the R group (rubber having an unsaturated carbon bond in the main chain) of JIS K6397 on the surface side on which the nonwoven fabric is conveyed. Is applied.
- the grip on the belt can be improved.
- the rubber resin may be styrene-butadiene rubber.
- Another aspect of the present invention is a woven fabric for non-woven fabric.
- This non-woven fabric is coated with a rubber resin classified into JIS K6397 M group (rubber having a saturated main chain of polymethylene type) on the surface side on which the non-woven fabric is transported.
- JIS K6397 M group rubber having a saturated main chain of polymethylene type
- the grip on the belt can be improved.
- the rubber resin may be acrylic rubber.
- the rubber resin may be water-soluble before curing. As a result, if the rubber resin before curing is water-soluble, even if the solvent volatilizes during curing, adverse effects on the environment and human health can be reduced.
- the coefficient of static friction on the surface side may be in the range of 0.25 to 0.90. This makes it possible to improve the grip on the belt. When the coefficient of static friction is 0.90 or less, the non-woven fabric web at the time of manufacture is sufficiently diffused on the belt, and the uniformity of the web is not impaired. Further, when the static friction coefficient is 0.25 or more, a sufficient grip force for the nonwoven fabric web can be obtained.

図3は、不織布用多層織物の静摩擦力を測定するための装置の概略構成を示す模式図である。
図4は、リリース性評価試験を説明するための模式図である。図4に示す試験方法では、はじめに壁130に不織布用多層織物108を固定する。次に、不織布用多層織物108に綿132を押し当て、綿132から手を離し、綿132が落下するか否かを観察した。
以下、実施例1-1に係る不織布用多層織物の構成について図面を参照して説明する。図5は、実施例1-1に係る不織布用多層織物の完全組織を示す意匠図である。図6は、図5に示す意匠図における各経糸に沿った断面図である。なお、図5において、経糸対(4Uと4U’及び8Uと8U’)は、上面側経糸が並置されているため、便宜上2列に分けて記載してある。
実施例1-2に係る不織布用多層織物は、実施例1-1に係る不織布用多層織物と同様の完全組織を有し、不織布が搬送される表面側に、織物を構成する糸の材質と異なる樹脂が塗布されている。具体的には、JISK6397のRグループ(主鎖に不飽和炭素結合をもつゴム)に分類されるゴム製樹脂が塗布されている点が実施例1-1と異なる。これにより、ベルトにおけるグリップ性を向上できる。ここで、実施例1-2に係るゴム製樹脂は、スチレンブタジエンゴムである。また、ゴム製樹脂は、水溶性であってもよい。
実施例1-3に係る不織布用多層織物は、実施例1-2に係る不織布用多層織物の表面に塗布されているゴム製樹脂と同じスチレンブタジエンゴムが塗布されているが、樹脂の硬度を高めるために、塗布する際の樹脂の濃度を変更している。実施例1-3に係る不織布用多層織物に塗布されたスチレンブタジエンゴムの硬化後の硬さは、デュロメータ硬さ(ショアA)で50であった。
実施例1-4に係る不織布用多層織物は、実施例1-2に係る不織布用多層織物の表面に塗布されているゴム製樹脂と同じスチレンブタジエンゴムが塗布されているが、樹脂の硬度を高めるために、塗布する際の樹脂の濃度を変更している。実施例1-4に係る不織布用多層織物に塗布されたスチレンブタジエンゴムの硬化後の硬さは、デュロメータ硬さ(ショアA)で15であった。
比較例1に係る不織布用多層織物は、実施例1-1に係る不織布用多層織物40と比較して、不織布が搬送される表面側にゴム製樹脂が塗布されていない点が異なり、それ以外は実質的に同じである。
比較例2に係る不織布用多層織物は、比較例1に係る不織布用多層織物と比較して、不織布が搬送される表面側に粘着性樹脂(例えば、シリコーン樹脂)が塗布されている点が異なり、それ以外は実質的に同じである。
比較例3に係る不織布用多層織物は、比較例1に係る不織布用多層織物と比較して、不織布が搬送される表面側にエンボス加工が施されている点が異なり、それ以外は実質的に同じである。
本実施の形態に係る不織布用多層織物からなるベルトを使用し続けると、ベルト上に汚れが付着、堆積する。そのため、高圧のシャワーで汚れを洗浄する必要があり、耐シャワー性が高いことが求められる。ここで、耐シャワー性が高いとは、高圧のシャワーで洗浄する際に、織物の表面に塗布されている樹脂が剥離しにくいことを言う。耐シャワー性が低いと、樹脂の剥離により不織布用多層織物のグリップ性能が低下する。
不織布用多層織物の表面の樹脂の粘着力が高いと、搬送する不織布がベルト表面から浮きにくくなるため、安定した搬送が可能となる。一方、ベルトから次工程へ移る際のリリース性が低下するため、不織布製造装置や製造条件に応じた適切な粘着力が必要になる。
以下、実施例2に係る不織布用多層織物の構成について図面を参照して説明する。図8は、実施例2に係る不織布用多層織物の完全組織を示す意匠図である。図9は、図8に示す意匠図における各経糸に沿った断面図である。
以下、実施例3に係る不織布用多層織物の構成について図面を参照して説明する。図10は、実施例3に係る不織布用多層織物の完全組織を示す意匠図である。図11は、図10に示す意匠図における各経糸に沿った断面図である。
以下、実施例4に係る不織布用多層織物の構成について図面を参照して説明する。図12は、実施例4に係る不織布用多層織物の完全組織を示す意匠図である。図13は、図12に示す意匠図における各経糸に沿った断面図である。
以下、実施例5に係る不織布用多層織物の構成について図面を参照して説明する。図14は、実施例5に係る不織布用多層織物の完全組織を示す意匠図である。図15は、図14に示す意匠図における各経糸に沿った断面図である。
以下、実施例6に係る不織布用多層織物の構成について図面を参照して説明する。図16は、実施例6に係る不織布用多層織物の完全組織を示す意匠図である。図17は、図16に示す意匠図における各経糸に沿った断面図である。
以下、実施例7に係る不織布用多層織物の構成について図面を参照して説明する。図18は、実施例7に係る不織布用多層織物の完全組織を示す意匠図である。図19は、図18に示す意匠図における各経糸に沿った断面図である。
図21は、実施例8に係る不織布用多層織物の完全組織を示す意匠図である。図22は、図21に示す意匠図における各経糸に沿った断面図である。
図23は、実施例9に係る不織布用多層織物の完全組織を示す意匠図である。図24は、図23に示す意匠図における各経糸に沿った断面図である。
一部の経糸は、完全組織に含まれる緯糸よりも更に外側の両端部でループを形成し、不織布が搬送される表面側に上面側織物が位置するように、各ループにピントル線を通すことで、各不織布用多層織物が無端状の不織布用ベルトとなる。
