Description
本発明は、濡れ感が少ない多層構造織編物および該織編物を用いてなる繊維製品に関する。 The present invention relates to a multilayer structure woven or knitted fabric with less wet feeling and a fiber product using the woven or knitted fabric.
従来、スポーツ衣料、インナー衣料、裏地など生地が肌に直接触れる用途において、発汗時や降雨時に生地と肌とが密着し濡れ感やべとつき感などの問題があった。
かかる対策として、異型断面形状の合成繊維を用いたり、各種の繊維を組合わせて織編物を得ることにより、織編物の吸水量を向上させたり、汗を肌面から外気側表面に素早く移行させ、肌面をドライな状態に保つことが提案されている（例えば、特許文献１、特許文献２、特許文献３、特許文献５参照）。
Conventionally, in applications where the fabric is in direct contact with the skin, such as sports clothing, inner clothing, and lining, the fabric and skin are in close contact when sweating or raining, and there are problems such as a feeling of wetness and stickiness.
As countermeasures, we can improve the water absorption of the woven or knitted fabric by using a synthetic fiber with an irregular cross-sectional shape or combine various fibers to obtain a woven or knitted fabric, or quickly transfer sweat from the skin surface to the outside air surface. It has been proposed to keep the skin surface dry (see, for example,
しかしながら、これらの織編物では、肌面から外気側表面への汗の移行が十分でなく、かつ外気側表面に移行した汗が手や腕などの露出した部分に触れると不快であり、また、外気側表面に移行した汗により外気側表面に濡れジミが残って見栄えが悪いといった問題があった。
なお、衣料用途、インナー衣料、特にスポーツ衣料などの用途では、ナノファイバーと称せられる超極細繊維を用いて、超極細繊維特有の風合いを有する布帛が提案されている。（例えば、特許文献６、特許文献７、特許文献８、特許文献９参照）。
However, in these woven and knitted fabrics, the transfer of sweat from the skin surface to the outside air side surface is not sufficient, and the sweat that has moved to the outside air side surface is uncomfortable when it touches exposed parts such as hands and arms, There has been a problem that wet spots are left on the outside air surface due to the sweat that has migrated to the outside air surface and the appearance is poor.
For applications such as apparel and inner apparel, particularly sports apparel, fabrics having a texture unique to ultrafine fibers have been proposed using ultrafine fibers called nanofibers. (For example, see Patent Document 6, Patent Document 7,
本発明は上記の背景に鑑みなされたものであり、その目的は、濡れ感が少ない多層構造織編物および該織編物を用いてなる繊維製品を提供することにある。 The present invention has been made in view of the above background, and an object of the present invention is to provide a multilayer structure woven or knitted fabric with less wet feeling and a fiber product using the woven or knitted fabric.
本発明者は上記の課題を達成するため鋭意検討した結果、２層構造または３層構造を有する多層構造織編物において、表層および／または中間層に単繊維径１０００ｎｍ以下のナノファイバーを配し、裏層に単繊維径が１０００ｎｍより大の糸条を配することにより濡れ感が少ない多層構造織編物が得られることを見出し、さらに鋭意検討を重ねることにより本発明を完成するに至った。 As a result of intensive studies to achieve the above-mentioned problems, the present inventor arranged nanofibers having a single fiber diameter of 1000 nm or less on the surface layer and / or the intermediate layer in a multilayer structure woven or knitted fabric having a two-layer structure or a three-layer structure, It has been found that a multi-layered woven or knitted fabric with less wet feeling can be obtained by arranging a yarn having a single fiber diameter larger than 1000 nm in the back layer, and the present invention has been completed by further earnest studies.
かくして、本発明によれば「表層および裏層の２層構造、または、表層および中間層および裏層の３層構造を有する多層構造織編物であって、表層および／または中間層に単繊維径１０００ｎｍ以下のナノファイバーＡが配され、裏層に単繊維径が１０００ｎｍより大の糸条Ｂが配されてなることを特徴とする多層構造織編物。」が提供される。 Thus, according to the present invention, “a multilayer structure woven or knitted fabric having a two-layer structure of a surface layer and a back layer, or a three-layer structure of a surface layer, an intermediate layer, and a back layer, and having a single fiber diameter in the surface layer and / or the intermediate layer” A multi-layered woven or knitted fabric characterized in that nanofibers A of 1000 nm or less are arranged, and yarn B having a single fiber diameter larger than 1000 nm is arranged in the back layer.
その際、前記ナノファイバーＡがポリエステルからなることが好ましい。また、前記ナノファイバーＡのフィラメント数が５００本以上であることが好ましい。また、前記糸条Ｂがポリエステルからなることが好ましい。かかる糸条Ｂは仮撚捲縮加工糸であることが好ましい。 In that case, it is preferable that the said nanofiber A consists of polyester. Further, the number of filaments of the nanofiber A is preferably 500 or more. The yarn B is preferably made of polyester. Such yarn B is preferably a false twist crimped yarn.
本発明の多層構造織編物において、織編物が編組織を有する編物であることが好ましい。また、多層構造織編物の裏面において、ベトツキ力が９８ｃＮ（１００ｇｒ）以下であることが好ましい。ただし、ベトツキ力は以下の方法で測定するものとする。すなわち、直径８ｃｍの金属ローラーに長さ１５ｃｍ、幅６ｃｍの編地を載せ、一端をストレス・ストレイン・ゲージに取り付け、編地のもう一端に重さ９．８ｃＮ（１０ｇｆ）のクリップを取り付ける。次に金属ローラーを７ｃｍ／ｓｅｃの表面速度で回転させながら注射器で金属ローラーと編地の間に５ｃｍ３の水を注入し、この時編地にかかる張力をストレス・ストレイン・ゲージにて測定し、その最大値でベトツキ力を評価する。また、多層構造織編物の裏面において、ＪＩＳＬ１９０７−５．１．１（滴下法）により生地裏面より水滴１滴を摘下し３分経過した後の、裏面の拡散面積（ｍｍ２）が５０ｍｍ２以下であることが好ましい。 In the multilayer structure woven or knitted fabric of the present invention, the woven or knitted fabric is preferably a knitted fabric having a knitted structure. Moreover, it is preferable that the sticking force is 98 cN (100 gr) or less on the back surface of the multilayer structure woven or knitted fabric. However, the stickiness is measured by the following method. That is, a knitted fabric having a length of 15 cm and a width of 6 cm is placed on a metal roller having a diameter of 8 cm, one end is attached to a stress strain gauge, and a clip having a weight of 9.8 cN (10 gf) is attached to the other end of the knitted fabric. Next, while rotating the metal roller at a surface speed of 7 cm / sec, 5 cm 3 of water is injected between the metal roller and the knitted fabric with a syringe, and the tension applied to the knitted fabric at this time is measured with a stress strain gauge. The stickiness is evaluated at the maximum value. Further, on the back surface of the multi-layer structure woven or knitted fabric, the diffusion area (mm 2 ) of the back surface after 3 minutes have passed after dropping one drop of water from the back surface of the fabric by JISL 1907-5.1.1 (drop method) is 50 mm 2. The following is preferable.

本発明によれば、濡れ感が少ない多層構造織編物および該織編物を用いてなる繊維製品が得られる。 According to the present invention, a multilayer structure woven or knitted fabric with less wet feeling and a fiber product using the woven or knitted fabric can be obtained.
以下、本発明の実施の形態について詳細に説明する。
本発明の多層構造織編物には、単繊維径が１０００ｎｍ以下のナノファイバーＡと単繊維径が１０００ｎｍより大の糸条Ｂとが含まれ、前記ナノファイバーＡが表層および／または中間層に配され、裏層に糸条Ｂが配される。ここで、表層とは最も外気側に位置する層であり、裏層とは最も肌側に位置する層である。
Hereinafter, embodiments of the present invention will be described in detail.
The multilayer structure woven or knitted fabric of the present invention includes nanofibers A having a single fiber diameter of 1000 nm or less and yarns B having a single fiber diameter of more than 1000 nm, and the nanofiber A is arranged on the surface layer and / or the intermediate layer. The yarn B is arranged on the back layer. Here, the surface layer is a layer located closest to the outside air, and the back layer is a layer located closest to the skin.
前記ナノファイバーＡにおいて、その単繊維径（単繊維の直径）が１０〜１０００ｎｍ（より好ましくは１００〜８００ｎｍ）の範囲内であることが好ましい。かかる単繊維径を単繊維繊度に換算すると、０．０００００１〜０．０１ｄｔｅｘに相当する。該単繊維径が１０ｎｍよりも小さい場合は繊維強度が低下するおそれがある。逆に、該単繊維径が１０００ｎｍよりも大きい場合は、肌側に位置する裏層で吸収した汗が表層へ移行し難くなり、本発明の主目的である、少ない濡れ感が得られ難くなるおそれがある。ここで、単繊維の断面形状が丸断面以外の異型断面である場合には、外接円の直径を単繊維径とする。なお、単繊維径は、透過型電子顕微鏡で繊維の横断面を撮影することにより測定が可能である。 In the said nanofiber A, it is preferable that the single fiber diameter (diameter of a single fiber) exists in the range of 10-1000 nm (more preferably 100-800 nm). When the single fiber diameter is converted into a single fiber fineness, it corresponds to 0.000001 to 0.01 dtex. If the single fiber diameter is smaller than 10 nm, the fiber strength may decrease. On the contrary, when the single fiber diameter is larger than 1000 nm, the sweat absorbed by the back layer located on the skin side is not easily transferred to the surface layer, and it is difficult to obtain a little wet feeling, which is the main object of the present invention. There is a fear. Here, when the cross-sectional shape of the single fiber is an atypical cross section other than the round cross section, the diameter of the circumscribed circle is defined as the single fiber diameter. The single fiber diameter can be measured by photographing the cross section of the fiber with a transmission electron microscope.
前記ナノファイバーＡにおいて、フィラメント数は特に限定されないが、超極細繊維特有の風合いを得る上で５００本以上（より好ましくは２０００〜１００００本）であることが好ましい。また、ナノファイバーＡの総繊度（単繊維繊度とフィラメント数との積）としては、５〜１５０ｄｔｅｘの範囲内であることが好ましい。 In the nanofiber A, the number of filaments is not particularly limited, but is preferably 500 or more (more preferably 2000 to 10,000) in order to obtain a texture peculiar to ultrafine fibers. The total fineness of the nanofiber A (the product of the single fiber fineness and the number of filaments) is preferably in the range of 5 to 150 dtex.
前記ナノファイバーＡの繊維形態は特に限定されないが、長繊維（マルチフィラメント糸）であることが好ましい。単繊維の断面形状も特に限定されず、丸、三角、扁平、中空など公知の断面形状でよい。また、通常の空気加工、仮撚捲縮加工が施されていてもさしつかえない。 The fiber form of the nanofiber A is not particularly limited, but is preferably a long fiber (multifilament yarn). The cross-sectional shape of the single fiber is not particularly limited, and may be a known cross-sectional shape such as a circle, a triangle, a flat shape, or a hollow shape. In addition, normal air processing and false twist crimping may be applied.
前記ナノファイバーＡを形成するポリマーの種類としては特に限定されず、ポリエステル、ポリアミド、ポリオレフィンなどの通常の繊維形成性ポリマーでよい。なかでも、ポリエチレンテレフタレートやポリトリメチレンテレフタレート、ポリブチレンテレフタレート、ポリ乳酸、第３成分を共重合させたポリエステルなどが好ましく例示される。かかるポリエステルとしては、マテリアルリサイクルまたはケミカルリサイクルされたポリエステルであってもよい。さらには、特開２００４−２７００９７号公報や特開２００４−２１１２６８号公報に記載されているような、特定のリン化合物およびチタン化合物を含む触媒を用いて得られたポリエステルでもよい。該ポリマー中には、本発明の目的を損なわない範囲内で必要に応じて、微細孔形成剤、カチオン染料可染剤、着色防止剤、熱安定剤、蛍光増白剤、艶消し剤、着色剤、吸湿剤、無機微粒子が１種または２種以上含まれていてもよい。 The type of polymer forming the nanofiber A is not particularly limited, and may be a normal fiber-forming polymer such as polyester, polyamide, and polyolefin. Among these, polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polylactic acid, polyester obtained by copolymerizing the third component, and the like are preferably exemplified. Such polyester may be material recycled or chemically recycled polyester. Furthermore, the polyester obtained using the catalyst containing the specific phosphorus compound and titanium compound which are described in Unexamined-Japanese-Patent No. 2004-270097 and 2004-21268 may be sufficient. In the polymer, a fine pore forming agent, a cationic dye dyeing agent, an anti-coloring agent, a heat stabilizer, a fluorescent whitening agent, a matting agent, a coloring agent may be added as necessary within the range not impairing the object of the present invention. 1 type (s) or 2 or more types of an agent, a hygroscopic agent, and inorganic fine particles may be contained.
一方、糸条Ｂは、その単繊維径が１０００ｎｍより大（好ましくは２〜２２μｍ）であることが肝要である。該単繊維径が１０００ｎｍ（１μｍ）以下であると、肌側に位置する裏層で吸収した汗が表層へ移行し難くなり、本発明の主目的である、少ない濡れ感が得られ難くなるおそれがある。ここで、単繊維の断面形状が丸断面以外の異型断面である場合には、外接円の直径を単繊維径とする。なお、単繊維径は、前記と同様、透過型電子顕微鏡で繊維の横断面を撮影することにより測定が可能である。 On the other hand, it is important that the yarn B has a single fiber diameter larger than 1000 nm (preferably 2 to 22 μm).
