Description
本発明はべとつき防止織物に関する。さらに詳しくは、二重織物であって、裏面のみが撥水性を呈することによりべとつきを防止できる片面撥水性二重織物および該片面撥水性二重織物を用いてなる繊維製品に関する。 The present invention relates to an anti-sticking fabric. More specifically, the present invention relates to a single-sided water-repellent double woven fabric that is a double woven fabric and can prevent stickiness by exhibiting water repellency only on the back surface, and a fiber product using the single-sided water-repellent double woven fabric.
スポーツ時などに多量の汗をかくと、衣服が肌に貼りつき、べとついた感覚を生じるため、従来、布帛の肌側面（裏面）のみに撥水性を付与することが提案されている。例えば、撥水性布帛と非撥水性布帛とを貼り合せる方法（例えば特許文献１参照）や布帛の片面のみに撥水加工を施す方法（例えば特許文献２参照）などが知られている。 When a large amount of sweat is taken during sports or the like, the clothes stick to the skin and give a sticky sensation. Therefore, it has been conventionally proposed to impart water repellency only to the skin side (back surface) of the fabric. For example, a method of bonding a water-repellent fabric and a non-water-repellent fabric (for example, refer to Patent Document 1), a method of performing water-repellent processing only on one side of the fabric (for example, refer to Patent Document 2), and the like are known.
しかしながら、撥水性布帛と非撥水性布帛とを貼り合せたものでは、生地が重くなってしまい着用快適性が損なわれるという問題があった。一方、布帛の片面のみに撥水加工を施すには、布帛の厚みを厚くするか布帛の織編密度をあげないと、反対側面に撥水加工剤が抜け出してしまうという問題があった。
なお、撥水加工を施した糸条を肌側表面に配した編地は、特許文献３で提案されている。
However, when the water-repellent fabric and the non-water-repellent fabric are bonded together, there is a problem that the fabric becomes heavy and wear comfort is impaired. On the other hand, in order to perform the water-repellent treatment only on one side of the fabric, there is a problem that the water-repellent agent escapes on the opposite side unless the thickness of the fabric is increased or the woven / knitted density of the fabric is increased.
In addition, the knitted fabric which arranged the thread | yarn which performed the water repellent process on the skin side surface is proposed by patent document 3. As shown in FIG.
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、二重織物であって、織物の厚さや織密度を高めることなく、片面のみが撥水性を呈することによりべとつきを防止できる片面撥水性二重織物および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-described background, and the object thereof is a double woven fabric, and can prevent stickiness by exhibiting water repellency only on one side without increasing the thickness or woven density of the woven fabric. It is to provide a single-sided water-repellent double woven fabric and a textile product.
本発明者らは、上記目的を達成するため鋭意検討した結果、二重織物において、糸条の段階で撥水加工された糸条で裏面側を構成し、かつ撥水加工されていない糸条で表面側を構成することにより、べとつきを防止できる片面撥水性二重織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に想到した。 As a result of intensive studies to achieve the above object, the inventors of the present invention have, as a result of the double woven fabric, a yarn that is water-repellent processed at the yarn stage and the back side is composed of yarn that is not water-repellent. The present inventors have found that a single-sided water-repellent double woven fabric capable of preventing stickiness can be obtained by constituting the surface side, and have further intensively studied to arrive at the present invention.
かくして、本発明によれば「二重織物であって、糸条の段階で撥水加工された糸条Ａで裏面側が構成され、かつ撥水加工されていない糸条Ｂで表面側が構成されてなることを特徴とする片面撥水性二重織物。」が提供される。 Thus, according to the present invention, “the back side is constituted by the yarn A which is a double woven fabric and water-repellent processed at the yarn stage, and the front side is constituted by the yarn B which is not water-repellent processed. A single-sided water-repellent double woven fabric characterized in that. "
その際、前記の糸条Ａおよび糸条Ｂがともにポリエステル繊維からなることが好ましい。また、前記の糸条Ａの単糸繊度が１．５ｄｔｅｘ以下であることが好ましい。かかる糸条Ａが仮撚捲縮加工糸条であることが好ましい。また、前記の糸条Ａにおいて、フッ素系撥水剤により撥水加工されていることが好ましい。前記の糸条Ａにおいて、撥水剤の付着量が糸条Ａの重量に対し１〜４０重量％の範囲内であることが好ましい。本発明の片面撥水性多層構造織物において、目付けが３００ｇ／ｍ２以下であることが好ましい。 At that time, it is preferable that both the yarn A and the yarn B are made of polyester fibers. Moreover, it is preferable that the single yarn fineness of the said thread A is 1.5 dtex or less. The yarn A is preferably a false twist crimped yarn. Further, the yarn A is preferably water-repellent processed with a fluorine-based water repellent. In the above-described yarn A, it is preferable that the amount of the water repellent adhered is in the range of 1 to 40% by weight with respect to the weight of the yarn A.

また、本発明によれば、前記の片面撥水性二重織物を用いてなる、インナーウエアー、スキーウエアー、ウインドブレーカー、ゴルフウエアー、Ｔシャツ、コート、ジャケット、およびパンツから群より選択されるいずれかの繊維製品が提供される。 Moreover, according to the present invention, any one selected from the group consisting of inner wear, ski wear, windbreaker, golf wear, T-shirt, coat, jacket, and pants, using the one-sided water-repellent double fabric. Textile products are provided.
本発明によれば、二重織物であって、織物の厚さや織密度を高めることなく、片面のみが撥水性を呈することによりべとつきが防止できる片面撥水性二重織物および繊維製品が得られる。 According to the present invention, a single-sided water-repellent double woven fabric and a fiber product which are double woven fabrics and can prevent stickiness by exhibiting water repellency only on one side without increasing the thickness and woven density of the woven 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。
まず、本発明の二重織物において、二重織物を使用する際に外気側に位置する側を表面側、一方、肌側に位置する側を裏面側とする。
本発明の片面撥水性二重織物において、糸条の段階で撥水加工された糸条Ａで裏面側が構成され、かつ撥水加工されていない糸条Ｂで表面側が構成される。
Hereinafter, embodiments of the present invention will be described in detail.
First, in the double woven fabric of the present invention, when using the double woven fabric, the side positioned on the outside air side is defined as the front side, and the side positioned on the skin side is defined as the back side.
In the single-sided water-repellent double woven fabric of the present invention, the back surface side is constituted by the yarn A that has been subjected to water-repellent processing at the yarn stage, and the front surface side is constituted by the yarn B that has not been subjected to water-repellent processing.
前記の糸条Ａを構成する繊維としては特に限定されず、ポリエステルやナイロンなどの合成繊維、アセテートなどの半合成繊維、レーヨン、キュプラなどの再生繊維、綿や麻などの天然繊維などいずれでもよい。なかでも、繊維強度や取扱いの容易さの点で、ポリエチレンテレフタレート、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、第３成分を共重合させたポリエステルなどのポリエステル系繊維が好ましく例示される。かかる繊維の繊維形態も特に限定されず、長繊維（マルチフィラメント糸条）でもよいし、短繊維でもよい。さらには、仮撚捲縮加工や空気加工が施されていてもよい。特に長繊維に仮撚捲縮加工が施された仮撚捲縮加工糸であると、さらに優れた撥水性が得られ好ましい。 The fiber constituting the yarn A is not particularly limited, and may be any of synthetic fibers such as polyester and nylon, semi-synthetic fibers such as acetate, regenerated fibers such as rayon and cupra, and natural fibers such as cotton and hemp. . Of these, polyester fibers such as polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, and polyester obtained by copolymerizing the third component are preferably exemplified in terms of fiber strength and ease of handling. The fiber form of such fibers is not particularly limited, and may be long fibers (multifilament yarns) or short fibers. Furthermore, false twist crimping or air processing may be applied. In particular, a false twisted crimped yarn obtained by subjecting long fibers to false twisted crimp processing is preferable because further excellent water repellency is obtained.
糸条Ａの繊度は特に限定されないが、優れた撥水性を得る上で単糸繊度は小さいほどよく、１．５ｄｔｅｘ以下（好ましくは０．１〜１．２ｄｔｅｘ）であることが好ましい。また、糸条Ａのフィラメント数は優れた撥水性を得る上で多いほどよく、３０本以上（好ましくは４０〜３００本）であることが好ましい。糸条Ａの総繊度としては、布帛強度や風合いの点や、総繊度で３３〜５００ｄｔｅｘの範囲が適当である。また、単糸の横断面形状も特に限定されるものではなく、通常の丸型だけでなく、扁平、三角、Ｙ型、Ｔ型、Ｕ型などの異型であってもよい。 The fineness of the yarn A is not particularly limited, but in order to obtain excellent water repellency, the single yarn fineness is preferably as small as possible, and is preferably 1.5 dtex or less (preferably 0.1 to 1.2 dtex). Further, the number of filaments of the yarn A is preferably as large as possible to obtain excellent water repellency, and is preferably 30 or more (preferably 40 to 300). The total fineness of the yarn A is suitably in the range of 33 to 500 dtex in terms of fabric strength, texture, and total fineness. Further, the cross-sectional shape of the single yarn is not particularly limited, and may be not only a normal round shape but also a different shape such as a flat shape, a triangular shape, a Y shape, a T shape, and a U shape.
なお、前記糸条Ａの繊維中には、微細孔形成剤、カチオン可染剤、着色防止剤、熱安定剤、蛍光増白剤、艶消し剤、着色剤、帯電防止剤、無機微粒子等が１種又は２種以上含まれていてもよい。
前記の糸条Ａは、糸条の段階で撥水加工されている必要がある。織物に製織した後に撥水加工を施すと、織物の反対側面に撥水加工剤が抜け出してしまい好ましくない。
In addition, in the fibers of the thread A, there are micropore forming agents, cationic dyes, anti-coloring agents, heat stabilizers, fluorescent whitening agents, matting agents, coloring agents, antistatic agents, inorganic fine particles, and the like. 1 type or 2 or more types may be contained.
The yarn A needs to be water-repellent at the yarn stage. If water repellent finish is applied after weaving the fabric, the water repellent finishes on the opposite side of the fabric, which is not preferable.
撥水加工の際に用いる撥水加工剤としては特に限定されないが、フッ素系撥水剤（例えば、旭硝子（株）製アサヒガードＬＳ−３１７（商品名）など）が好適である。また、撥水加工剤の付着量としては、糸条Ａの重量に対し１〜４０重量％の範囲内であることが好ましい。該付着量が１重量％よりも小さいと十分な撥水性が得られないおそれがある。逆に、該付着量が４０重量％よりも大きいとコストアップとなるおそれがある。 The water repellent finish used in the water repellent finish is not particularly limited, but a fluorine-based water repellent (for example, Asahi Guard LS-317 (trade name) manufactured by Asahi Glass Co., Ltd.) is preferable. Moreover, it is preferable that it is in the range of 1-40 weight% with respect to the weight of the thread | yarn A as an adhesion amount of a water repellent finishing agent. If the adhesion amount is less than 1% by weight, sufficient water repellency may not be obtained. Conversely, if the amount of adhesion is greater than 40% by weight, the cost may increase.
一方、糸条Ｂは通常の糸条でよく、繊維表面に撥水剤が付着していないこと以外は、糸条Ａと同様でよい。もちろん、繊維種類や繊度等を糸条Ａと異ならせても何らさしつかえない。 On the other hand, the yarn B may be a normal yarn, and may be the same as the yarn A except that the water repellent is not attached to the fiber surface. Of course, there is no problem even if the fiber type and fineness are different from those of the yarn A.
本発明の片面撥水性二重織物において、裏面側は糸条Ａのみで構成される必要はなく、裏面側表面に下記式で定義する露出度で１０％以内糸条Ｂが露出していてもよい。ただし、裏面側の表面に凹凸がある場合は、肌と接触する凸部表面について露出度を測定する。
裏面層（凸部）表面に露出した糸条Ｂの露出度（％）＝（ＳＢ／Ｓ１）×１００
ただし、ＳＢは裏面層（凸部）表面に露出した糸条Ｂの総面積（ｍｍ２）であり、Ｓ１は織物裏面層（凸部）の表面積（ｍｍ２）である。
In the single-sided water-repellent double woven fabric of the present invention, the back side does not need to be composed of only the yarn A, and the yarn B is exposed on the back side surface with an exposure degree defined by the following formula within 10%. Good. However, when the surface on the back side has irregularities, the degree of exposure is measured for the convex surface that comes into contact with the skin.
Degree of exposure of thread B exposed on the surface of the back layer (convex portion) (%) = (SB / S1) × 100
However, SB is the total area (mm 2 ) of the yarn B exposed on the surface of the back surface layer (convex portion), and S1 is the surface area (mm 2 ) of the fabric back surface layer (convex portion).
同様に、裏面層は糸条Ｂのみで構成される必要はなく、裏面層の表面に下記式で定義する露出度で１０％以内糸条Ａが露出していてもよい。
表面層表面に露出した糸条Ａの露出度（％）＝（ＳＡ／Ｓ２）×１００
ただし、ＳＡは表面層表面に露出した糸条Ａの総面積（ｍｍ２）であり、Ｓ２は織物表面積（ｍｍ２）である。
Similarly, the back surface layer does not need to be composed only of the yarn B, and the surface of the back surface layer may expose the yarn A within 10% with an exposure degree defined by the following formula.
Degree of exposure (%) of the yarn A exposed on the surface layer surface = (SA / S2) × 100
However, SA is the total area (mm 2 ) of the yarn A exposed on the surface layer surface, and S2 is the fabric surface area (mm 2 ).
本発明の片面撥水性二重織物において、織組織としては、たて二重織、よこ二重織等の片二重織組織、完全二重織組織などが例示され、表裏組織は同一でも異なっていてもよい。 In the single-sided water-repellent double woven fabric of the present invention, examples of the woven structure include a single double woven structure such as a vertical double woven or a weft double woven, a complete double woven structure, and the front and back structures are the same or different. It may be.
次に、本発明の片面撥水性二重織物の製造方法を例示する。
まず、撥水加工剤と必要に応じてメラミン樹脂などのバインダー樹脂を含む水溶液を準備し加工液とする。かかる加工液には、増粘剤などが含まれていてもよい。
Next, the manufacturing method of the single-sided water-repellent double fabric of the present invention is illustrated.
First, an aqueous solution containing a water-repellent agent and, if necessary, a binder resin such as a melamine resin is prepared as a processing liquid. Such a processing liquid may contain a thickener and the like.
次いで、該加工液を糸条に付与する。その際、付与方法は特に限定されず、例えば、１本糊付機等の糸加工機を用いて、加工液を受け皿状のトレイに入れ、その液中に糸条を通過させることにより加工液を付与することが好ましく例示される。糸条に加工液を付与した後、１３０〜１８０℃の温度で乾熱またはスチームで熱処理を施し糸条Ａとする。熱処理の前に必要に応じて絞りや乾燥を行ってもよい。
次いで、かかる糸条Ａと、撥水加工されていない糸条Ｂとを用いて、糸条Ａが裏面側に配され、かつ糸条Ｂが表面側に配された二重織物を製織する。
Next, the working fluid is applied to the yarn. At that time, the application method is not particularly limited. For example, by using a yarn processing machine such as a single gluing machine, the processing liquid is placed in a dish-shaped tray and the thread is passed through the processing liquid. Is preferably exemplified. After applying the working fluid to the yarn, it is heat treated with dry heat or steam at a temperature of 130 to 180 ° C. to obtain yarn A. You may squeeze and dry as needed before heat processing.
Next, a double woven fabric in which the yarn A is arranged on the back surface side and the yarn B is arranged on the front surface side is woven using the yarn A and the yarn B that is not water-repellent.
かくして得られた片面撥水性二重織物において、裏面側が糸条Ａで構成されているので、肌側表面は優れた撥水性を呈し織物が肌にべとつくことがない。また、外気側表面は非撥水性なので、汗は表面側に吸収される。その結果、優れた着用快適性が得られる。さらに、本発明の片面撥水性二重織物は生地の厚さや織密度が小さくても、片面のみが撥水性を呈する片面撥水性が得られる。織物の目付けとしては特に限定されないが、目付けが３００ｇ／ｍ２以下（好ましくは３０〜２００ｇ／ｍ２）であると本発明の効果が発揮されやすく好ましい。 In the single-sided water-repellent double woven fabric thus obtained, the back side is composed of the yarn A, so that the skin-side surface exhibits excellent water repellency and the fabric does not stick to the skin. Further, since the outside air surface is non-water-repellent, sweat is absorbed on the surface side. As a result, excellent wearing comfort is obtained. Furthermore, the single-sided water-repellent double woven fabric of the present invention can provide single-sided water-repellent properties in which only one side exhibits water repellency even if the fabric thickness and weave density are small. The basis weight of the woven fabric is not particularly limited, but it is preferable that the basis weight is 300 g / m 2 or less (preferably 30 to 200 g / m 2 ) because the effect of the present invention is easily exhibited.
なお、本発明の片面撥水性二重織物には、本発明の目的が損なわれない範囲であれば、常法のアルカリ減量加工、染色加工、起毛加工、紫外線遮蔽あるいは制電剤、抗菌剤、消臭剤、防虫剤、蓄光剤、再帰反射剤、マイナスイオン発生剤等の機能を付与する各種加工を付加適用してもよい。 In addition, the single-sided water-repellent double woven fabric of the present invention has a conventional alkali weight loss processing, dyeing processing, brushed processing, ultraviolet shielding or antistatic agent, antibacterial agent, as long as the object of the present invention is not impaired. Various processes that provide functions such as deodorant, insect repellent, phosphorescent agent, retroreflective agent, and negative ion generator may be additionally applied.
次に、本発明の繊維製品は、前記の片面撥水性二重織物を用いてなる、インナーウエアー、スキーウエアー、ウインドブレーカー、ゴルフウエアー、Ｔシャツ、コート、ジャケット、およびパンツから群より選択されるいずれかの繊維製品である。これらの繊維製品は前記の片面撥水性二重織物を用いているので、肌側表面は優れた撥水性を呈し織物が肌にべとつくことがない。また、外気側表面は非撥水性なので、汗は表面層側に吸収される。さらに、生地の厚さが小さくても、片面のみが撥水性を呈する片面撥水性が得られる。 Next, the textile product of the present invention is selected from the group consisting of inner wear, ski wear, windbreaker, golf wear, T-shirt, coat, jacket, and pants, using the single-sided water-repellent double fabric. Any fiber product. Since these textiles use the above-mentioned single-sided water-repellent double woven fabric, the skin-side surface exhibits excellent water repellency, and the woven fabric does not stick to the skin. Further, since the outside air surface is non-water-repellent, sweat is absorbed by the surface layer side. Furthermore, even if the thickness of the fabric is small, single-sided water repellency can be obtained in which only one side exhibits water repellency.
