Description
本発明は、汗などの水分を異方的に拡散することにより、スポーツ用衣料やインナー用衣料として用いた際、汗によるぬれ感やベトツキ感を低減することができる、着用快適性に優れた編地および衣料に関するものである。 The present invention is excellent in wear comfort by reducing moisture and stickiness due to sweat when used as sports clothing and inner clothing by anisotropically diffusing moisture such as sweat. It relates to knitted fabrics and clothing.
従来、合成繊維や天然繊維などからなる編地を、スポーツ用衣料やインナー用衣料などとして使用すると、肌からの発汗によりムレやベトツキが発生するという問題があった。
かかる対策として、異形断面形状の合成繊維を用いて、織編物の吸水量を向上させる方法や、汗を肌面から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できる特殊多層構造の編地が提案されている（特許文献１、特許文献２、特許文献３、特許文献４、特許文献５参照）。
しかしながら、これらの編地では、発汗初期に見られるような少量の発汗に対しては有効であるものの、多量に発汗した場合にはあまり効果が発現されなかった。
Conventionally, when a knitted fabric made of synthetic fiber or natural fiber is used as sports apparel or inner apparel, there has been a problem that stuffiness or stickiness occurs due to sweating from the skin.
As such measures, using synthetic fibers with irregular cross-sectional shapes, a method to improve the water absorption of woven or knitted fabrics, or a special multi-layer structure that can quickly transfer sweat from the skin surface to the surface and keep the skin surface dry Have been proposed (see Patent Document 1,
However, these knitted fabrics are effective against a small amount of perspiration as seen in the early stage of perspiration, but are not very effective when sweating a large amount.
本発明は前記従来技術に鑑みなされたものであり、その課題は、汗などの水分を異方的に拡散することにより、スポーツ用衣料やインナー用衣料として用いた際、汗によるぬれ感やベトツキ感を低減することができる、着用快適性に優れた編地および衣料を提供することにある。 The present invention has been made in view of the above prior art, and its problem is that when wet, such as sweat, is anisotropically diffused, when used as sports apparel or inner apparel, it feels wet and feels sticky due to sweat. An object of the present invention is to provide a knitted fabric and apparel that can reduce the feeling and are excellent in wearing comfort.
本発明者らは上記の課題を達成するため、スポーツシャツやインナーウエアーの着用テストを行い、発汗時のぬれ感やベトツキ感の発生原因を調べたところ、運動により発汗した際、吸収される汗の量が衣服の部位によって異なり、局所的に生地の飽和吸水量を超えている個所があり、その個所でぬれ感やベトツキ感を感じていることを見出した。 In order to achieve the above-mentioned problems, the present inventors conducted a wearing test of sports shirts and innerwear and examined the cause of the wetness and stickiness when sweating. It was found that there was a place where the amount of water was different depending on the part of the clothes, and locally exceeded the saturated water absorption amount of the fabric, and the wetness and stickiness were felt at that place.
具体的には、半そでのスポーツシャツを着用し運動した場合、首、胸、背中（上部）といった上半身の中でも特に上部位において生地が汗をよく吸っており、ぬれ感やベトツキ感が強いことが分った。 Specifically, when wearing a half-sleeve sports shirt and exercising, the upper part of the upper body such as the neck, chest, and back (upper part) absorbs sweat well, especially in the upper part, and there is a strong feeling of wetting and stickiness. I understand.
この原因の一つは、スポーツシャツの場合、特に胸や背中（上部）は生地が体に沿って接触しているが、腹や背中（下部）は離れているためと考えられる。
さらに大きい原因としては、汗は頭や顔で特に多くかき、その汗は首筋を伝わって、胸や背中（上部）に移動するため、シャツの中でも特に胸や背中（上部）に飽和吸水量を越えた量の汗が存在するためと考えられる。
One reason for this is thought to be that in the case of sports shirts, the chest and back (upper part) are in contact with the fabric along the body, but the abdomen and back (lower part) are separated.
The bigger cause is that sweat is especially high on the head and face, and the sweat travels through the neck and moves to the chest and back (upper part). This is thought to be because there is an excessive amount of sweat.
以上のことから、ぬれ感やベトツキ感を低減させるためには、衣服の体幹上部（胸や背中上部）で吸った汗をいかにして衣服の体幹下部（腹や背中下部）に移動させるかが重要であることが分った。 Based on the above, in order to reduce the feeling of wetting and stickiness, the sweat absorbed by the upper trunk of the clothes (chest and upper back) is moved to the lower trunk (abdomen and lower back) of the clothes. I found that is important.
かくして、本発明によれば「水との接触角が８０度未満の繊維からなる糸条Ａと、水との接触角が８０度以上の撥水性繊維からなる糸条Ｂとで構成される編地であって、該編地の表面に前記糸条Ａのみからなる領域ＳＡと前記糸条Ｂのみからなる領域ＳＢが存在し、かつ領域ＳＢが縞状のパターンで存在していることを特徴とする異方的な吸水拡散性を有する編地。」が提供される。 Thus, according to the present invention, “knitting composed of a yarn A made of fibers having a contact angle with water of less than 80 degrees and a yarn B made of water-repellent fibers having a contact angle with water of 80 degrees or more.

In the knitted fabric of the present invention, it is preferable that the water-absorbing diffusivity in one of the warp direction and the weft direction is twice or more that of the other direction.
However, the water-absorbing diffusibility is the diffusion distance (mm) in the warp or weft direction after 3 minutes have passed after dropping one drop of water on the knitted fabric according to JIS L1907-5.1.1 (drop method). It is.
また本発明によれば、前記の編地を用いてなり、領域ＳＢのパターンの連続する方向が上下方向となるよう縫製してなる衣料が提供される。 Further, according to the present invention, there is provided a garment formed by using the knitted fabric and sewn so that the continuous direction of the pattern of the region SB is the vertical direction.
本発明によれば、汗などの水分を異方的に拡散することにより、スポーツ用衣料やインナー用衣料として用いた際、汗によるぬれ感やベトツキ感を低減することができる、着用快適性に優れた編地および衣料が得られる。 According to the present invention, when it is used as sports clothing or inner clothing by anisotropically diffusing moisture such as sweat, it is possible to reduce the feeling of wetting and stickiness due to sweat, for the comfort of wearing. Excellent knitted fabric and clothing are obtained.
まず、本発明の編物は、水との接触角が８０度未満の繊維からなる糸条Ａと、水との接触角が８０度以上の撥水性繊維からなる糸条Ｂとで構成される。
ここで、糸条Ａを形成する、水との接触角が８０度未満の繊維としては、綿や絹などの天然繊維、レーヨン繊維やアセテート繊維などの半合成繊維、ポリエステル繊維やナイロン繊維などが例示される。なかでも、繊維強度などの点でポリエステル繊維が好ましい。
First, the knitted fabric of the present invention is composed of a yarn A made of fibers having a contact angle with water of less than 80 degrees and a yarn B made of water-repellent fibers having a contact angle with water of 80 degrees or more.
Here, the fibers forming the thread A and having a contact angle with water of less than 80 degrees include natural fibers such as cotton and silk, semi-synthetic fibers such as rayon fibers and acetate fibers, polyester fibers and nylon fibers. Illustrated. Of these, polyester fibers are preferable in terms of fiber strength and the like.
一方、糸条Ｂを形成する撥水性繊維としては、フッ素樹脂繊維、ポリオレフィン繊維、撥水加工を施したポリエステル繊維などが例示される。
これらの繊維中には、本発明の主目的が損なわれない範囲内であれば、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、吸湿剤、無機微粒子等が１種又は２種以上含まれていてもよい。
On the other hand, examples of the water-repellent fibers forming the yarn B include fluororesin fibers, polyolefin fibers, and polyester fibers subjected to water-repellent processing.
In these fibers, as long as the main purpose of the present invention is not impaired, a micropore forming agent, a cationic dyeing agent, a coloring inhibitor, a thermal stabilizer, a fluorescent brightening agent, a matting agent, coloring 1 type, or 2 or more types of agents, antistatic agents, hygroscopic agents, inorganic fine particles, and the like may be contained.
また、前記糸条Ａや糸条Ｂを形成する繊維の繊維形態は特に限定されず、短繊維でもよいし長繊維でもよい。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が採用できる。糸条の総繊度、単糸繊度、フィラメント数も特に限定されないが、風合いや生産性の点で総繊度３０〜３００ｄｔｅｘ、単糸繊度０．６〜１０ｄｔｅｘ、フィラメント数１０〜３００本の範囲が好ましい。 Moreover, the fiber form of the fiber which forms the said thread | yarn A or the thread | yarn B is not specifically limited, A short fiber may be sufficient and a long fiber may be sufficient. The cross-sectional shape of the fiber is not particularly limited, and a known cross-sectional shape such as a circle, a triangle, a flat shape, or a hollow shape can be employed. The total fineness of the yarn, the single yarn fineness, and the number of filaments are not particularly limited, but in terms of texture and productivity, a total fineness of 30 to 300 dtex, a single yarn fineness of 0.6 to 10 dtex, and a number of filaments of 10 to 300 are preferable. .
次に、本発明の編物において、編地表面に前記糸条Ａのみからなる領域ＳＡと前記糸条Ｂのみから領域ＳＢが存在し、かつ領域ＳＢが縞状のパターンで存在している。
かかるパターンの具体的な例としては、図１に模式的に示す経縞（ストライプ）状パターン、図２に模式的に示す緯縞状パターン、および斜め縞状パターンなど、経方向または緯方向のどちらか一方に連続するパターンが例示される。格子パターンや市松パターンでは十分な異方的拡散性が得られず好ましくない。かかるパターンにおいて、吸汗した汗は、糸条Ａのみからなる領域ＳＡに沿って異方的に拡散するため、汗によるぬれ感やベトツキ感を低減することができる。
Next, in the knitted fabric of the present invention, a region SA consisting only of the yarn A and a region SB only from the yarn B exist on the surface of the knitted fabric, and the region SB exists in a striped pattern.
Specific examples of such a pattern include warp-like (striped) pattern schematically shown in FIG. 1, latitudinal-like pattern schematically shown in FIG. The pattern which continues in either one is illustrated. A lattice pattern or checkered pattern is not preferable because sufficient anisotropic diffusivity cannot be obtained. In such a pattern, the perspired sweat is anisotropically diffused along the region SA consisting only of the yarn A, so that the wet feeling and the sticky feeling due to the sweat can be reduced.
前記の領域ＳＢの巾ｗとしては、０．１〜５ｍｍ（より好ましくは０．２〜４ｍｍ）の範囲内であることが好ましい。かかる領域ＳＢの巾ｗが５ｍｍよりも大きいと、編地の吸水性が低下し、編地を衣料として着用した際、汗が肌に残り易くなるおそれがある。 The width w of the region SB is preferably in the range of 0.1 to 5 mm (more preferably 0.2 to 4 mm). When the width w of the region SB is larger than 5 mm, the water absorption of the knitted fabric is lowered, and sweat may easily remain on the skin when the knitted fabric is worn as clothing.

Moreover, it is preferable that it is in the range of 0.2-10 mm (more preferably 0.5-5 mm) as the space | interval d of adjacent area | region SB.
本発明の編地において、領域ＳＢの面積割合は編地全体の１０〜５０％の範囲内であることが好ましい。また、該編地の表面が前記糸条Ａのみからなる領域ＳＡと前記糸条Ｂのみから領域ＳＢが存在し、かつ領域ＳＢが縞状のパターンで存在している限り、糸条Ａと糸条Ｂとで構成される領域ＳＣが存在していてもさしつかえない。なお、領域ＳＢは、編地の経方向または緯方向のどちらか一方の方向に編地の端から端まで連続していることが好ましいが、本発明の主目的である異方的な吸水拡散性が得られる限り、不連続な個所があってもさしつかえない。 In the knitted fabric of the present invention, the area ratio of the region SB is preferably in the range of 10 to 50% of the entire knitted fabric. In addition, as long as the surface of the knitted fabric includes the region SA composed only of the yarn A and the region SB composed only of the yarn B, and the region SB exists in a striped pattern, the yarn A and the yarn There may be an area SC composed of the strip B. The region SB is preferably continuous from end to end of the knitted fabric in either the warp direction or the weft direction of the knitted fabric, but the anisotropic water absorption diffusion that is the main object of the present invention. As long as sex is obtained, there may be discontinuous parts.
本発明の編地を製造方法としては、以下の製造方法が例示される。すなわち、まず通常の経編機を使用して、糸条Ａをフルセットでフロント筬に通し、糸条Ｂをフルセットでバック筬に通し、フロント１０−０１、バック２２−００の編組織で編成する方法や、フロント筬およびバック筬に糸条Ａと糸条Ｂとを複数本交互のボーダー配列でセットし、フロント１０−２３、バック１２−１０の編組織で編成する方法、さらには、丸編機を用いて、糸条Ａと糸条Ｂとを複数本交互のボーダー配列でセットし天竺やスムースの編組織で編成する方法などが例示される。 The following manufacturing method is illustrated as a manufacturing method of the knitted fabric of this invention. That is, first, using a normal warp knitting machine, the yarn A is passed through the front kite with the full set, the yarn B is passed through the back kite with the full set, and the knitting structure of the front 10-01 and the back 22-00 is used. A method of knitting, a method of setting a plurality of yarns A and yarns B in an alternating border arrangement on the front and back folds, and knitting with a knitted structure of the front 10-23 and the back 12-10, Examples thereof include a method of setting a plurality of yarns A and yarns B in an alternating border arrangement using a circular knitting machine, and knitting with a knitted fabric such as a tengu or smooth.
製編された編地には、常法の染色仕上げ加工が施されてもよい。さらには、本発明の主目的が損なわれない範囲であれば、常法の吸水加工、起毛加工、紫外線遮蔽あるいは抗菌剤、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。 The knitted fabric that has been knitted may be subjected to a conventional dyeing finish. Furthermore, as long as the main purpose of the present invention is not impaired, conventional water-absorbing processing, brushed processing, ultraviolet shielding or antibacterial agent, deodorant, insect repellent, phosphorescent agent, retroreflective agent, negative ion generator Various processings that provide such functions may be additionally applied.
本発明の編地において、編地中に前記糸条Ａのみからなる領域ＳＡと前記糸条Ｂのみから領域ＳＢが存在し、かつ領域ＳＢが縞状のパターンを形成しているので、吸汗した汗は領域ＳＡに沿って拡散し、異方的な吸水拡散性を呈することとなる。 In the knitted fabric of the present invention, the region SA is formed only from the yarn A and the region SB is formed from only the yarn B in the knitted fabric, and the region SB forms a striped pattern. Sweat diffuses along the region SA and exhibits anisotropic water absorption and diffusibility.
かかる吸水分散性としては、経方向および緯方向のうち、どちらか一方向の吸水拡散性が他方向の２倍以上（より好ましくは５〜５０倍）であることが好ましい。どちらか一方向の水拡散性が他方向の２倍未満であると、該編地を用いて衣服を縫製し着用した際、汗が多く溜まる体幹上部から体幹下部への移動が十分に起こらず、体幹上部で肌に汗が残り、ぬれ感やベトツキ感を感じるやすくなるおそれがある。 As such water-absorbing dispersibility, it is preferable that the water-absorbing diffusivity in one of the warp direction and the weft direction is twice or more (more preferably 5 to 50 times) that of the other direction. If the water diffusibility in one direction is less than twice that in the other direction, when the clothes are sewn and worn using the knitted fabric, the movement from the upper trunk to the lower trunk is sufficient when sweat is accumulated. It does not occur, and sweat may remain on the upper part of the trunk, which may make it easier to feel wet or sticky.
ただし、吸水拡散性とは、ＪＩＳＬ１９０７−５．１．１（滴下法）により編地に水滴１滴を摘下し３分経過した後の、経方向または緯方向の拡散距離（ｍｍ）のことである。
次に本発明の繊維製品は、前記の編地を用いてなり、領域ＳＢのパターンの連続する方向が上下方向となるよう縫製してなる衣料である。かかる衣料において、汗が多く溜まる体幹上部から体幹下部への移動が十分に起こるため、体幹上部に汗が残らず、汗によるぬれ感やベトツキ感を低減することができるため、スポーツ用衣料やインナー用衣料として好適に使用することができる。
However, the water-absorbing diffusibility is the diffusion distance (mm) in the warp or weft direction after 3 minutes have passed after dropping one drop of water on the knitted fabric according to JIS L1907-5.1.1 (drop method). It is.
Next, the textile product of the present invention is a garment formed by using the above-described knitted fabric and sewn so that the continuous direction of the pattern of the region SB is the vertical direction. In such apparel, the movement from the upper trunk where the sweat accumulates to the lower trunk occurs sufficiently, so that no sweat remains on the upper trunk, and wetting and stickiness due to sweat can be reduced. It can be suitably used as clothing and clothing for inner wear.
次に本発明の実施例及び比較例を詳述するが、本発明はこれらによって限定されるものではない。なお、実施例中の各測定項目は下記の方法で測定した。 Next, although the Example and comparative example of this invention are explained in full detail, this invention is not limited by these. In addition, each measurement item in an Example was measured with the following method.
＜繊維と水との接触角＞
試料となる繊維を、撚り係数が１５０００となるよう撚りをかけ、該撚糸１２ｃｍをカットし、輪を作り端を結ぶ。このサンプルを接触角測定機（レスカ社製ＷＥＴ６０００）を用いて、水中に上げ下げして、水の中に引き込まれる力（濡れ応力）を測定し、下記式より接触角を算出する。
<Contact angle between fiber and water>
The sample fiber is twisted so that the twisting coefficient is 15000, the twisted yarn 12 cm is cut, a ring is formed, and the ends are tied. This sample is raised and lowered into water using a contact angle measuring machine (WET6000 manufactured by Reska Co., Ltd.), the force (wet stress) drawn into the water is measured, and the contact angle is calculated from the following formula.
撚係数＝撚数（Ｔ／ｍ）×（糸条の総繊度（ｄｔｅｘ）×９÷１０）１／２
Twist coefficient = twist number (T / m) × (total fineness of yarn (dtex) × 9 ÷ 10) 1/2
＜吸水拡散性＞ＪＩＳＬ１９０７−５．１．１（滴下法）により編地に水滴１滴を摘下し３分経過した後の、経方向および緯方向の拡散距離（ｍｍ）を測定した。そして、経方向および緯方向のうち、拡散距離の大きい方（Ｌｍａｘ）と小さい方（Ｌｍｉｎ）との比（Ｌｍａｘ／Ｌｍｉｎ）を算出した。なお、ｎ数は５とし、平均値を求めた。 <Water-absorbing diffusivity> After a drop of water was dropped on the knitted fabric by JISL 1907-5.1.1 (drop method), the diffusion distance (mm) in the warp direction and the weft direction after 3 minutes was measured. Then, a ratio (Lmax / Lmin) between the longer diffusion distance (Lmax) and the smaller diffusion distance (Lmin) in the longitudinal direction and the weft direction was calculated. In addition, n number was set to 5, and the average value was calculated | required.
＜ベトツキ感＞実施例および比較例の編物を用いて半そでＴシャツを縫製し、温度２８℃、湿度５０％ＲＨに調節された室内にて、被験者３人が下記の運動工程を行った際の着用快適性をベトツキ感大、ベトツキ感小（着用快適性に優れる）の２段階に評価した。
