Description

ここでは、フィラメント糸１２のキュプラの重量割合を２０％、３０％、４０％、５０％とし、スパン糸１４のうちのレーヨンの重量割合を２０％、３０％、４０％、５０％として、残りの重量割合をポリエステル糸にして、表１に示す１２種類の交編である天竺の生地を形成した。この各生地について、良好な方から、優れている項目を○、綿と同程度を◇、綿より少し劣る△、綿より劣る×として評価した。そして総合評価について、優秀をＡ、良をＢ、普通をＣ、好ましくないものをＤとした。
【００１３】
この結果、表１に示す通り、キュプラ４０％、レーヨン３０％、ポリエステル３０％のものが最も良い成績であり、次にキュプラが４０％で、ポリエステルとレーヨンの比が２：１と、１：２としたもの、及びキュプラが３０％、ポリエステルとレーヨンの比が３：４と、２：５としたものが良好な成績であった。
【００１４】
これにより、総合評価でＢ以上のものは、ベタツキ感や蒸れ感がなく、吸湿性・吸水性があり、しかも冷えすぎず清涼感のある生地を形成することができることがわかった。
【００１５】
また、この発明による生地の清涼感について測定した。清涼感を良くするには、熱伝導率が高く、水分の移動が速いものがよい。この条件に適している繊維は、親水性繊維であって毛羽の少ないフィラメント糸である。従って、本願発明では、キュプラ等の親水性フィラメント糸を用いている。清涼感の評価方法として、冷温感評価値ｑｍａｘについて測定した。
【００１６】
ここでは、試験装置としてサーモラボII（カトーテック社製）を使用し、図２に示すような試験を行った。試験は、面積９ｃｍ^２、質量９．７９ｇの純銅板に熱を貯え、これが試料表面に接触した直後、貯えられた熱量が低温側の試料物体に移動する熱量のピーク値を測定した。このｑｍａｘ値が大きいほど冷たく感じ、小さいほど暖かく感じる。
【００１７】
試験は、２０℃、６５％ＲＨの環境下で、２０℃に保たれた定温台２０の表面に、１２．５ｃｍ×１２．５ｃｍの試料である生地１０を載せ、その上にさらに、３０℃に熱した５ｃｍ×５ｃｍの熱源板２２を載せる。このときに、熱源板２２から定温台２０に移動する熱量のピーク値ｑｍａｘを冷温感値として測定した。
【００１８】
この試験結果によれば、上記の評価Ａであった、キュプラ４０％、レーヨン３０％、ポリエステル３０％のもので、ｑｍａｘが０．１５２（Ｗ／ｃｍ^２）を示し、比較対照として、綿１００％の天竺編の生地では、ｑｍａｘが０．１３０（Ｗ／ｃｍ^２）であった。従って、本願発明による生地の冷温感評価値は、綿と比較して高く、熱の移動が速く清涼感が高いことがわかった。
【００１９】
次に、この発明による生地の速乾性について試験した。速乾性を良くするには、液相汗の吸水、気相汗の吸湿が良く、濡れても渇きが速いものでなければならない。この条件に適している繊維は、親水性繊維（蒸れ感が少ない）であって毛羽のあるスパン糸（ベタツキが少ない）、異型断面糸（速く乾く）である。速乾性の評価方法として、平均熱放散速度を測定した。
【００２０】
ここでは、試験装置としてサーモラボII（カトーテック社製）を使用し、試験は、定温台の上に試料を乗せ、湿潤−乾燥の過程で定温台を一定温度を保つために消費した電力を求め、その経時変化と乾燥時間を求めた。
【００２１】
試験方法は、２０℃、６５％ＲＨの環境下において、３６℃に保たれた１０ｃｍ×１０ｃｍの定温台の上に７ｃｍ×７ｃｍの絹（含水用布）を乗せ、さらにその上に１２．５ｃｍ×１２．５ｃｍの試料生地１０を載せ安定させる。その際、サーモラボ装置内の風速を０．３ｍ／ｓとする。この状態で初期乾燥時の消費電力を測定した後、一度試料をめくり、絹に水分を２ｃｃ加えて湿潤させ、試料を湿潤させる。その後、６０秒毎に消費電力を測定し、初期乾燥時の消費電力に戻るまでの時間（分）を求めた。この結果を図３のグラフに示す。
【００２２】
この試験では、本発明による上記評価Ａのキュプラ４０％、レーヨン３０％、ポリエステル３０％の天竺生地１０の乾燥時間は約２３分であり、比較対照の綿１００%天竺生地の乾燥時間約２８分と比較して、乾くのが速いことがわかった。また、湿潤から乾燥までの定温台の消費電力の変化を見ると、図３に示すように、上記評価Ａの生地１０においては、湿潤直後の約５分間の消費電力が高く、水分の気化による気化熱が大きいため、定温にするための消費電力が多くなっていることがわかる。これは、汗をかいた直後においては、気化熱による体温冷却効果が高いことを示す。さらに、その後は、綿１００％の対照と比較して消費電力が低く、ある程度水分が蒸発すると、保温効果が働き、綿１００％の対照と比べて冷却効果が低い。これにより、汗をかいた後発汗が止まって若干汗が乾くと、それ以上は高い冷却効果を発揮せず、接触冷感が低すぎることがないと言う効果を示す。
【００２３】
以上より、本発明による天竺生地１０は、吸水、吸湿性に優れ、さらに速乾性にも優れており、蒸れ感やベタツキ感が少ないものである。
【００２４】
以上の結果から、この生地の用途としては、肌着や運動用衣服が好ましく、競技用のシャツ・パンツ、ゴルフシャツ、テニスシャツ、トレーニングウェア、野球ユニフォーム、ハーフパンツなど幅広く適用できるものである。さらに、作業用衣服のように運動や発汗を伴う環境の衣服にも適用できるものである。
【００２５】
【発明の効果】
この発明の生地と衣服によれば、肌着や運動用衣服等に用いた際に、着用初期の気相状発汗による蒸れ感が軽減されると同時に、液状発汗も肌側から表側に素早く吸水、拡散、蒸発されることでベタツキ感もなく、着用時の冷涼感があり、快適性が極めて高いものである。また、洗濯後の速乾性も高く、取り扱い性にも優れている。

BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to underwear and sports clothes that are directly worn on the skin, and relates to a refreshing fabric and clothes.
[0002]
[Prior art]
[Patent Document 1]
JP, 2001-295158, A Conventionally, for underwear and athletic clothing directly worn on the skin, 100% natural fibers such as cotton, 100% synthetic fibers such as polyester and polyamide, or knitting of natural fibers and synthetic fibers There is a ground. In general, an underwear or an exercise garment worn in contact with the skin is preferably a hygroscopic or water-absorbent fabric such as cotton. However, after sweating a large amount in the summer or after intense exercise, the fabric that absorbed a large amount of liquid-phase sweat touched the skin and caused a sticky feeling, which was not preferable. Therefore, in sports clothes that sweat a lot, chemical fibers such as polyester with low water absorption have been used for parts that directly touch the skin and underwear.
[0003]
[Problems to be solved by the invention]
100% natural fibers such as cotton, or those with a synthetic fiber on the surface and cotton or cotton / polyester blended yarn are excellent in hygroscopicity, water absorption, water retention, and absorbs sweat well. After that, sweat does not evaporate easily, and it is inferior in continuous sweat absorption, resulting in a sticky feeling on the skin, and if it is worn wet with sweat due to its high water absorption, There was also a problem that the feeling of contact cooling was too high. In addition, after washing, even after dehydration, considerable moisture remains inside the fiber, and drying takes a long time.
[0004]
On the other hand, 100% synthetic fiber such as polyester fiber has a short drying time after washing, but has no hygroscopicity and a feeling of stuffiness, and since it is hydrophobic, the water absorption rate when in contact with sweat is low. There is also a problem that the water absorption and movement of sweat is not performed due to inferior perspiration and the perspiration remains on the skin, causing a sticky feeling. Furthermore, polyester fiber has a low thermal conductivity, so the temperature in the clothes rises, and since it is not hygroscopic, it does not absorb sweat in the vapor phase during normal wear, resulting in high humidity and stuffiness. The feeling of wearing was not good.
[0005]
The present invention has been made in view of the above-described conventional technology, and has an object to provide a fabric and clothes having a hygroscopic property, a feeling of stuffiness and a sticky feeling, and a refreshing feeling.
[0006]
[Means for Solving the Problems]
The present invention relates to a fabric in which a spun yarn obtained by blending a hydrophobic fiber such as polyester and a hydrophilic regenerated fiber such as rayon, and a cellulose-based hydrophilic filament yarn such as cupra are substantially alternately positioned, and the fabric It is clothes such as underwear and exercise clothes.
[0007]
The hydrophilic filament yarn and the spun yarn obtained by blending the hydrophobic fiber and the hydrophilic regenerated fiber are provided at a weight ratio in the range of 3: 7 to 4: 6. In the spun yarn, the weight ratio of the hydrophobic fiber to the hydrophilic regenerated fiber is in the range of about 2: 1 to 2: 5. More preferably, the hydrophilic yarns 40%, a fabric woven spun yarn blended into one another equal weight ratio of hydrophobic fibers and hydrophilic regenerated fibers in a weight ratio of 60%.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the fabric and clothes of the present invention will be described in detail. This embodiment shows a case where it is applied to an undergarment. The fabric 10 of this embodiment shown in FIG. 1 is made of a knitted sheet, and is made of a filament yarn 12 that is a cupra of cellulosic regenerated fibers, and a polyester short fiber. The spun yarn 14 in which a certain hydrophobic fiber and a hydrophilic regenerated fiber that is a short rayon fiber are blended is knitted almost alternately. Cupra is a hydrophilic regenerated fiber. The spun yarn 14 is obtained by blending polyester fibers that are hydrophobic fibers and rayon that is hydrophilic regenerated fibers in an equal proportion of 30% by weight of the whole. In the fabric 10, the ratio of the spun yarn 14 as a whole is 60% by weight, and the ratio of the filament yarn 12 made of cupra is 40% by weight.
[0009]
According to the fabric and clothes of this embodiment, the hydrophilic cupra and the hydrophilic rayon provide sufficient moisture absorption and water absorption, and there is no stuffiness even when touching the skin directly. In addition, the filament yarn 12 made of cupra is hydrophilic and has a large contact area with the skin, and thus has a cool feeling of contact. Moreover, since the spun yarn 14 has a small contact area with the skin, there is little stickiness even when touching the skin. In addition, by including the filament yarn 12, the appearance of the fabric is smooth, and the filament yarn 12 made of cupra is quick to dry even if it is hydrophilic. Furthermore, the filament yarn 12 has no fluff and has a refreshing feeling when in contact with the skin.
[0010]
Furthermore, since the fabric 10 includes a spun yarn 14 in which polyester fibers and rayon are blended, even if a polyester of hydrophobic fibers is mixed, the moisture absorption and water absorption are relatively high. Moreover, the polyester fibers are hydrophobic, have good sweat evaporation, and dry quickly after washing. In addition, after sucking up the sweat, a cool feeling is generated by the heat of vaporization, but it is not preferable that the cool feeling by the heat of vaporization is too strong. However, the spun yarn 14 blended with polyester short fibers adds heat retention and gives a cool feeling of contact. Is never too high. Further, since the filament yarn 12 and the spun yarn 14 of this embodiment have a relatively high heat resistance, they can be dried by, for example, a tumbler dryer.
[0011]
【Example】
Next, Table 1 shows the measurement results of various fabrics with respect to the feeling of wearing the underwear with the fabrics of this invention.
[0012]
[Table 1]

Here, the weight percentage of the cupra of the filament yarn 12 is 20%, 30%, 40% and 50%, and the weight percentage of the rayon in the spun yarn 14 is 20%, 30%, 40% and 50%, and the rest The weight ratio of was made into a polyester yarn to form a dough of tendon, which is 12 types of knitting as shown in Table 1. For each of these fabrics, the items that were excellent were evaluated as “Excellent”, “◇” as the same as cotton, “Δ” slightly inferior to cotton, and “×” inferior to cotton. In the overall evaluation, A was excellent, B was good, C was normal, and D was not preferable.
[0013]
As a result, as shown in Table 1, the best results were obtained with cupra 40%, rayon 30%, polyester 30%, then cupra 40%, and the ratio of polyester to rayon was 2: 1, 1: Good results were obtained when the ratio was 2 and the cupra was 30% and the ratio of polyester to rayon was 3: 4 and 2: 5.
[0014]
As a result, it was found that those having B or higher in overall evaluation have no stickiness or stuffiness, hygroscopicity and water absorption, and can form a refreshing fabric without being too cold.
[0015]
Further, the coolness of the fabric according to the present invention was measured. In order to improve the refreshing feeling, it is preferable that the heat conductivity is high and the moisture movement is fast. A fiber suitable for this condition is a filament yarn that is hydrophilic and has few fluff. Therefore, in the present invention, hydrophilic filament yarn such as cupra is used. As an evaluation method of the cool feeling, the cool / warm feeling evaluation value qmax was measured.
[0016]
Here, Thermolab II (manufactured by Kato Tech Co., Ltd.) was used as a test apparatus, and the test as shown in FIG. 2 was performed. In the test, heat was stored in a pure copper plate having an area of 9 cm ² and a mass of 9.79 g, and immediately after the heat contacted the sample surface, the peak value of the amount of heat transferred to the low-temperature sample object was measured. The larger the qmax value, the colder the feeling, and the smaller the qmax value, the warmer.
[0017]
In the test, the fabric 10 as a sample of 12.5 cm × 12.5 cm was placed on the surface of the constant temperature table 20 kept at 20 ° C. in an environment of 20 ° C. and 65% RH, and further, 30 ° C. A heated 5 cm × 5 cm heat source plate 22 is placed on the plate. At this time, the peak value qmax of the amount of heat moving from the heat source plate 22 to the constant temperature table 20 was measured as a cold / hot sensation value.
[0018]
According to the test results, the evaluation A was cupra 40%, rayon 30%, polyester 30%, and qmax was 0.152 (W / cm ² ). In the case of a 10% woven fabric, the qmax was 0.130 (W / cm ² ). Therefore, it was found that the coolness evaluation value of the fabric according to the present invention was higher than that of cotton, and the heat transfer was quick and the coolness was high.
[0019]
Next, the dough according to the present invention was tested for quick drying. In order to improve quick-drying, water must be absorbed by liquid-phase sweat and vapor-phase sweat and must be thirsty even when wet. Suitable fibers for this condition are hydrophilic fibers (low stuffiness), fluffy spun yarn (low stickiness), and modified cross-section yarn (fast dry). The average heat dissipation rate was measured as a method for evaluating quick drying.
[0020]
Here, Thermolab II (manufactured by Kato Tech Co., Ltd.) is used as a test apparatus, and the test is to obtain the power consumed to keep the constant temperature table at a constant temperature during the wet-dry process by placing the sample on the temperature table. The change with time and the drying time were determined.
[0021]
The test method was to place 7 cm × 7 cm silk (water-containing cloth) on a 10 cm × 10 cm constant temperature table maintained at 36 ° C. in an environment of 20 ° C. and 65% RH, and further 12.5 cm thereon. A sample fabric 10 of 12.5 cm is placed and stabilized. At that time, the wind speed in the thermolab apparatus is set to 0.3 m / s. After measuring the power consumption at the initial drying in this state, the sample is turned once, and 2 cc of moisture is added to the silk to wet it, and the sample is wetted. Thereafter, the power consumption was measured every 60 seconds, and the time (minutes) required to return to the power consumption during the initial drying was determined. The result is shown in the graph of FIG.
[0022]
In this test, the drying time of the 10% cupra 40%, rayon 30%, and polyester 30% of the above-mentioned evaluation A according to the present invention is about 23 minutes, and the drying time of the comparative cotton 100% cotton fabric is about 28 minutes. It was found that it dries faster than In addition, looking at the change in power consumption of the constant temperature table from wet to dry, as shown in FIG. 3, the dough 10 of the evaluation A has high power consumption for about 5 minutes immediately after wetting, and is due to the evaporation of moisture. Since the heat of vaporization is large, it can be seen that the power consumption for making the temperature constant increases. This indicates that immediately after sweating, the body temperature cooling effect by the heat of vaporization is high. Furthermore, after that, the power consumption is low compared to the 100% cotton control, and when the moisture evaporates to some extent, the heat retaining effect works, and the cooling effect is low compared to the 100% cotton control. As a result, when sweating stops after sweating and the sweat is slightly dried, the effect of saying that the cooling effect is not too low and the high cooling effect is not exhibited.
[0023]
From the above, the tempura dough 10 according to the present invention is excellent in water absorption and hygroscopicity, and further in quick drying, and has little stuffiness and stickiness.
[0024]
From the above results, the use of this fabric is preferably underwear or sports clothes, and can be widely applied to competition shirts / pants, golf shirts, tennis shirts, training wear, baseball uniforms, and half pants. Furthermore, the present invention can be applied to clothes in an environment involving exercise and sweating such as work clothes.
[0025]
【The invention's effect】
According to the fabric and clothes of the present invention, when used for underwear, exercise clothes, etc., the feeling of stuffiness due to vapor-phase sweating at the initial stage of wear is reduced, while liquid sweat quickly absorbs water from the skin side to the front side, Diffusion and evaporation result in no stickiness, cool feeling when worn, and extremely high comfort. Moreover, the quick-drying property after washing is high, and the handleability is also excellent.
