Description

本発明は、布帛が大量の汗を吸収した場合において、当該布帛が肌離れ性が良好であるか否かを判定するための測定方法に関するものである。   The present invention relates to a measurement method for determining whether or not a fabric has good skin separation when the fabric absorbs a large amount of sweat.

マラソンやサッカー等の長時間の運動を伴うスポーツを行うと、大量の発汗によって着衣を構成している布帛が濡れ、肌に密着してベタツキ感が生じる。このベタツキ感は不快であると共に競技にも悪影響を及ぼす。かかるベタツキ感を緩和するために、競技者等は、着衣を掴んで肌から離す動作を繰り返すことにより、着衣と肌との間に強制的に空気を送り込むことを、無意識に行っている。かかる動作は、「ふいご作用」による放熱や汗の蒸散を目的とするものであり、自然法則にかなった動作である。したがって、着衣を構成している布帛が肌から離れやすければ、着衣を掴むまでもなく、運動中に「ふいご作用」が生じて、ベタツキ感が生じにくいと考えられる。よって、大量に吸水したときに肌から離れやすい布帛を用いれば、ベタツキ感の少ない着衣が得られることは自明である。   When a sport accompanied by long-time exercise such as marathon or soccer is performed, the cloth constituting the clothes is wet by a large amount of sweat, and the cloth is in close contact with the skin, resulting in a sticky feeling. This sticky feeling is unpleasant and adversely affects the competition. In order to alleviate such a feeling of stickiness, the athletes and the like unconsciously perform the operation of forcibly sending air between the clothing and the skin by repeatedly holding the clothing and releasing it from the skin. Such an operation is aimed at heat dissipation or sweat transpiration due to the “fluffy action”, and conforms to the laws of nature. Therefore, if the fabric constituting the clothes is easily separated from the skin, it is considered that a “fringing action” is generated during exercise and the sticky feeling is unlikely to occur without grasping the clothes. Therefore, it is self-evident that clothing with less stickiness can be obtained by using a fabric that is easily separated from the skin when a large amount of water is absorbed.

このため、ベタツキ感の少ない着衣を得ることを目的として、吸水した布帛と肌との密着性を評価する方法が種々提案されている。特許文献１には、乾燥時の布帛の摩擦係数に対する、水分付与時の布帛の摩擦係数の増加率を測定することにより、吸水布帛と肌との密着性を評価することが記載されている。特許文献２は、吸水しにくい撥水布帛に関するものであるが、金属ローラと布帛の間に水を注入して湿潤摩擦力を測定して、撥水布帛と肌との密着性を評価することが記載されている。特許文献３も、一部撥水加工した布帛に関するものであるが、水を所定量付与した布帛と人工皮脂を付与したフィルムとの摩擦係数を測定することにより、布帛と肌との密着性を評価することが記載されている   For this reason, various methods for evaluating the adhesion between the water-absorbed fabric and the skin have been proposed for the purpose of obtaining clothes with little stickiness. Patent Document 1 describes that the adhesion between the water-absorbing fabric and the skin is evaluated by measuring the increase rate of the friction coefficient of the fabric when moisture is applied to the friction coefficient of the fabric when drying. Patent Document 2 relates to a water-repellent fabric that hardly absorbs water, and measures wet friction force by injecting water between a metal roller and the fabric to evaluate the adhesion between the water-repellent fabric and the skin. Is described. Patent document 3 also relates to a fabric partially water-repellent processed, but by measuring the coefficient of friction between a fabric to which a predetermined amount of water is applied and a film to which artificial sebum is applied, the adhesion between the fabric and the skin is improved. It is described to be evaluated

しかしながら、特許文献１〜３に記載された測定方法は、いずれも、湿潤時又は水分付与時の摩擦係数を測定しているものであり、肌に対して水平方向に布帛が動くときの動きやすさを評価しているのであって、上記した肌に対して垂直方向に動く「ふいご作用」の生じやすさを評価しているものではない。   However, all of the measurement methods described in Patent Documents 1 to 3 measure the friction coefficient when wet or when moisture is applied, and are easy to move when the fabric moves in a horizontal direction with respect to the skin. However, it does not evaluate the ease with which the above-mentioned “fluffing action” that moves in the direction perpendicular to the skin occurs.

本発明の課題は、吸水した布帛が肌に対して垂直方向に動く「ふいご作用」が生じやすいか否かを判定しうる測定方法を提供することにある。   An object of the present invention is to provide a measurement method capable of determining whether or not a “fringing action” in which the absorbed fabric moves in a direction perpendicular to the skin is likely to occur.

「ふいご作用」が有効に奏せられるためには、吸水した布帛が肌に対して垂直方向に動きやすいか否かである。本発明者はこの点に着目し、吸水布帛が水平方向に動くときの摩擦係数ではなく、吸水布帛が垂直方向に動くときの荷重を測定することにより、肌離れ性を測定しようというものである。すなわち、本発明は、重心に引き上げ具が取り付けられ、水が付与された状態で平板に載置された吸水布帛を、該引き上げ具で該吸水布帛を垂直方向に引き上げて、引き上げ荷重を測定する吸水性布帛の肌離れ性測定方法であって、前記引き上げ具は、伸縮性部材と非伸縮性部材とが長手方向に繋がれているものであることを特徴とする吸水性布帛の肌離れ性測定方法に関するものである。 In order for the “fluffy action” to be effectively achieved, it is whether or not the absorbed fabric is easy to move in a direction perpendicular to the skin. The present inventor pays attention to this point and intends to measure skin separation by measuring the load when the water absorbent fabric moves in the vertical direction, not the coefficient of friction when the water absorbent fabric moves in the horizontal direction. . That is, in the present invention, a lifting tool is attached to the center of gravity, and the water absorbing cloth placed on a flat plate in a state where water is applied is pulled up in the vertical direction with the lifting tool to measure the lifting load. A method for measuring the skin-removability of a water-absorbent fabric , wherein the lifting tool has a stretchable member and a non-stretchable member connected in the longitudinal direction. It relates to a measurement method .

本発明に係る測定方法で用いる布帛は、吸水性布帛である。吸水性布帛としては、吸水加工が施された編織物や、レーヨン又はコットン繊維等の親水性繊維で構成された編織物が挙げられる。本発明に係る測定方法では、全面的に撥水加工が施された編織物は不適当である。なぜなら、布帛に対して十分な量の水を付与できないからである。本発明は、大量の汗を吸収したときの着衣の肌離れ性を評価するものであるから、汗を吸収し得ない全面撥水加工された編織物は対象としていない。   The fabric used in the measurement method according to the present invention is a water absorbent fabric. Examples of the water-absorbing fabric include a knitted fabric that has been subjected to water absorption processing and a knitted fabric composed of hydrophilic fibers such as rayon or cotton fibers. In the measurement method according to the present invention, a knitted fabric that has been subjected to a water repellent treatment on the entire surface is inappropriate. This is because a sufficient amount of water cannot be applied to the fabric. Since the present invention evaluates the separation of the skin when a large amount of sweat is absorbed, the knitted fabric subjected to water-repellent finish that cannot absorb sweat is not intended.

吸水性布帛の形状は任意であるが、一般的には正方形又は円形であるのが好ましい。本発明に係る測定方法において、引き上げ荷重は吸水布帛の重量と、吸水布帛と平板と間に存在する水による表面張力に依存するから、その重心が決定しやすく、重心から端縁までの長さがほぼ同じである正方形又は円形が好ましい。   The shape of the water-absorbent fabric is arbitrary, but is generally preferably a square or a circle. In the measuring method according to the present invention, the lifting load depends on the weight of the water absorbent fabric and the surface tension due to water existing between the water absorbent fabric and the flat plate, so that the center of gravity is easily determined and the length from the center of gravity to the edge. Are preferably the same square or circular.

吸水性布帛の重心には、引き上げ具が取り付けられる。引き上げ具としては、伸縮性部材と非伸縮性部材の両者を長手方向に繋いだものを用いる。ここで、伸縮性部材とは、比較的低い荷重である引き上げ荷重が負荷されたときに伸び、この引き上げ荷重を取り去ると縮む部材である。一般的に、輪ゴム等のゴムが用いられる。非伸縮性部材とは、比較的低い荷重である引き上げ荷重が負荷されても、実質的に伸びない部材のことである。一般的には、ミシン糸等の紡績糸、マルチフィラメント糸又はモノフィラメント糸が用いられる。引き上げ具を重心に取り付けるには、一般的に縫い針を用いればよい。引き上げ具を縫い針を用いて、重心の表面に通して、取り付ければよい。この際、縫い針が裏面に至らないようにして、重心の表面のみに引き上げ具を取り付けるのが好ましい。なぜなら、吸水性布帛の重心の裏面は平板と当接する面であるから、この裏面に引き上げ具が露出していると、この露出の影響で引き上げ荷重の測定に悪影響を与える恐れがあるからである。伸縮性部材と非伸縮性部材の両者を長手方向に繋いで引き上げ具とする具体例としては、たとえば、糸の一方端に輪ゴムを繋いでもよい。また、糸の輪と輪ゴムとを繋いでもよい。そして、糸を吸水布帛の重心に取り付けて引き上げ具とするのである。 A lifting tool is attached to the center of gravity of the water absorbent fabric. As the lifting tool , one in which both the stretchable member and the non-stretchable member are connected in the longitudinal direction is used. Here, the elastic member is a member that expands when a lifting load, which is a relatively low load, is applied, and contracts when the lifting load is removed. Generally, rubber such as rubber band is used. The non-stretchable member is a member that does not substantially expand even when a lifting load that is a relatively low load is applied. Generally, spun yarn such as sewing yarn, multifilament yarn or monofilament yarn is used. A sewing needle is generally used to attach the lifting tool to the center of gravity. The lifting tool may be attached by passing it through the surface of the center of gravity using a sewing needle. At this time, it is preferable to attach the lifting tool only to the surface of the center of gravity so that the sewing needle does not reach the back surface. This is because the back surface of the center of gravity of the water-absorbent fabric is a surface that comes into contact with the flat plate, and if the lifting tool is exposed on this back surface, there is a risk of adversely affecting the measurement of the lifting load due to the influence of this exposure. . Both elastic members and non-stretchable member Specific examples of the connecting by lifting element in the longitudinal direction, for example, may connect the rubber band on one end of the thread. Further, a thread ring and a rubber band may be connected. And a thread | yarn is attached to the gravity center of a water absorbing cloth , and is used as a raising tool.

また、非伸縮性部材としてタグピンを用いてもよい。タグピンというのは、膨出した頭部と張り出した棒部とがフィラメントで連結している合成樹脂製のもので、日本バノック社から「バノックピン」なる名称で市販されているものである。タグピンは、張り出した棒部を吸水性布帛の重心に貫通させることにより、容易に吸水布帛に取り付けられる。さらに、膨出した頭部に伸縮性部材及び／又はその他の非伸縮性部材を繋ぎ、このタグピンを吸水布帛の重心に取り付けて引き上げ具としてもよい。 A tag pin may be used as the non-stretchable member . The tag pin is made of a synthetic resin in which a bulging head and an overhanging bar portion are connected by a filament, and is commercially available under the name “Bannock pin” from Japan Bannock. The tag pin is easily attached to the water-absorbing fabric by passing the protruding bar portion through the center of gravity of the water-absorbing fabric. Further, the stretchable member and / or other non-stretchable member may be connected to the bulged head, and the tag pin may be attached to the center of gravity of the water-absorbing fabric.

吸水性布帛には水が付与される。水の付与量は任意であるが、一般的に１ｍ2当たり３００ｍｌ程度の付与量であるのが好ましい。また、水を過剰に付与してもよい。ここで、過剰とは、吸水性布帛が完全に保水できず雫が落ちる量のことを意味している。過剰の水が付与された吸水布帛は、平板と共に垂直にして、雫を切る。雫を切るには、垂直にして一定時間（たとえば６０〜１２０秒）保持していれば十分である。これによって、吸水布帛は大量の汗を吸収したときの状態（雫は落ちないけれども、べったりと濡れた状態）に類似した状態となる。雫を切った後、吸水布帛及び平板を水平にする。 Water is applied to the water absorbent fabric. The amount of water applied is arbitrary, but generally it is preferably about 300 ml per 1 m 2 . Moreover, you may provide water excessively. Here, “excess” means an amount by which the water-absorbing fabric cannot completely retain water and drops wrinkles. The water-absorbing fabric to which excess water has been applied is cut vertically along with the flat plate. In order to cut the cocoon, it is sufficient to keep it vertical for a certain time (for example, 60 to 120 seconds). As a result, the water-absorbing fabric is in a state similar to the state when a large amount of sweat is absorbed (the heel does not fall, but is wet and damp). After cutting the scissors, the absorbent fabric and flat plate are leveled.

水の付与は、吸水性布帛を平板に載置した後であってもよいし、平板に載置する前であってもよい。平板としても任意のものを用いうるが、一般的に、表面が平滑なアクリル板、金属板、石板又はシリコーン樹脂製板（模擬皮膚板）を用いることができる。平板の厚さ及び重量は、吸水布帛を引き上げたときに一緒に引き上げられない程度のものを採用する。なお、吸水布帛を平板に載置する際に、吸水布帛の裏面（肌に接する面）が平板に当接するようにして載置することはいうまでもない。   The application of water may be after the water-absorbing fabric is placed on the flat plate or before the water-absorbing fabric is placed on the flat plate. Although any plate can be used, generally, an acrylic plate, metal plate, stone plate or silicone resin plate (simulated skin plate) having a smooth surface can be used. The thickness and weight of the flat plate are such that they cannot be lifted together when the water absorbent fabric is pulled up. Needless to say, when the water-absorbing fabric is placed on the flat plate, the water-absorbing fabric is placed so that the back surface (the surface in contact with the skin) abuts the flat plate.

水平にした吸水布帛に取り付けられている引き上げ具の他端を、引張試験機の上把持部で把持して、上把持部を垂直方向に引き上げる。そうすると、吸水布帛も垂直方向に引き上げられ、最終的には平板から離れる。平板から離れる際に最大の引き上げ荷重が掛かるので、この荷重を読み取るのである。引き上げ具として、伸縮性部材と非伸縮性部材とが長手方向に繋がれているものを採用しているが、伸縮性部材を引張試験機の上把持部に把持するのが好ましい。引き上げ具中に伸縮性部材が存在していると、吸水布帛が平板から離れる際に伸びていた伸縮性部材が縮んで、一気に吸水布帛が上方に跳ね上がり、引き上げ荷重が一気に降下するので、最大の引き上げ荷重を判別しやすくなる。引張試験機で引き上げ具を引き上げる際の速度（引き上げ速度）は任意であるが、一般的に、５０〜５００ｍｍ／分であるのが好ましく、２００〜５００ｍｍ／分であるのがより好ましい。引き上げ速度が５０〜５００ｍｍ／分の範囲外であると、最大の引き上げ荷重の値が変動しやすくなり、誤差が大きくなる傾向が生じる。また、用いる引張試験機としては従来公知のものを任意に採用しうる。たとえば、株式会社ティ・エスエンジニアリング製の「ＴＥＮＳＩＬＯＮ（品番：ＵＣＴ−５００）」や株式会社島津製作所製の「オートグラフ（型番：ＡＧＳ−５ｋＮＸ）」等を用いることができる。なお、引張試験機を用いずに、簡易的にバネ秤を用いて測定してもよい。すなわち、バネ秤のフックに引き上げ具を繋ぎ、人手でバネ秤を垂直方向に引き上げ、吸水布帛が平板から離れるときのバネ秤の荷重を読み取って、引き上げ荷重を測定してもよい。 The other end of the lifting tool attached to the horizontal water-absorbing fabric is gripped by the upper gripping portion of the tensile tester, and the upper gripping portion is pulled up in the vertical direction. Then, the water absorbent fabric is also pulled up in the vertical direction, and finally leaves the flat plate. Since the maximum lifting load is applied when moving away from the flat plate, this load is read. As the lifting tool, a member in which the stretchable member and the non-stretchable member are connected in the longitudinal direction is adopted, but it is preferable that the stretchable member is gripped by the upper gripping portion of the tensile tester. If there is a stretchable member in the lifting tool, the stretchable member stretched when the water absorbent fabric leaves the flat plate shrinks, the water absorbent fabric jumps upward at a stretch, and the pulling load drops all at once. It becomes easy to distinguish the lifting load. The speed at which the lifting tool is pulled up by the tensile tester (pulling speed) is arbitrary, but generally it is preferably 50 to 500 mm / min, more preferably 200 to 500 mm / min. If the pulling speed is outside the range of 50 to 500 mm / min, the maximum pulling load value tends to fluctuate, and the error tends to increase. A conventionally known tensile tester can be arbitrarily used. For example, “TENSILON (product number: UCT-500)” manufactured by TS Engineering Co., Ltd. or “Autograph (model number: AGS-5kNX)” manufactured by Shimadzu Corporation can be used. In addition, you may measure using a spring balance simply, without using a tensile testing machine. That is, a lifting tool may be connected to the hook of the spring balance, the spring balance may be pulled up manually, and the load of the spring balance when the water absorbent fabric is separated from the flat plate may be read to measure the lifting load.

図１は、本発明の一例に係る測定方法を使用した場合の模式図を示したものである。１は平板であり、２は吸水布帛、３は非伸縮性部材、４は伸縮性部材及び５は引張試験機の上把持部である。そして、上把持部５を垂直方向に引き上げて、引き上げ荷重ｆを測定するのである。本発明に係る測定方法で種々の吸水性布帛を測定したところ、引き上げ荷重が低くなればなるほど、大量に発汗した際の肌離れ性が良好となることが判明した。引き上げ荷重の具体的数値は、吸水性布帛に付与する水の量によって異なる。吸水性布帛１ｍ2 当たり３００ｍｌ程度の水の付与量の場合、引き上げ荷重ｆが８ｃＮ以下であるものは肌離れ性が優れていることが確認されている。また、吸水性布帛に過剰の水を付与した場合、引き上げ荷重ｆが１００ｃＮ以下であるものは肌離れ性に優れていることが確認されている。   FIG. 1 shows a schematic diagram when a measuring method according to an example of the present invention is used. 1 is a flat plate, 2 is a water absorbent fabric, 3 is a non-stretchable member, 4 is a stretchable member, and 5 is an upper gripping portion of a tensile tester. Then, the upper gripping portion 5 is pulled up in the vertical direction and the lifting load f is measured. When various water-absorbing fabrics were measured by the measurement method according to the present invention, it was found that the lower the lifting load, the better the skin separation when sweating in large quantities. The specific value of the lifting load varies depending on the amount of water applied to the water absorbent fabric. In the case of an applied amount of water of about 300 ml per 1 m <2> of the water-absorbent fabric, it has been confirmed that those having a lifting load f of 8 cN or less have excellent skin separation. Moreover, when excess water is provided to the water-absorbent fabric, it has been confirmed that those having a lifting load f of 100 cN or less are excellent in skin separation.

本発明に係る吸水性布帛の肌離れ性測定方法は、吸水布帛が水平方向に移動するときの摩擦係数を測定するものではなく、吸水布帛が垂直方向に移動するときの引き上げ荷重を測定するものであるから、吸水布帛が肌に対して垂直方向に動く「ふいご作用」の生じやすさに相関しており、布帛の肌離れ性及びベタツキ感を評価するのに適している。   The skin-peeling property measuring method of the water-absorbing fabric according to the present invention does not measure the friction coefficient when the water-absorbing fabric moves in the horizontal direction, but measures the lifting load when the water-absorbing fabric moves in the vertical direction. Therefore, it correlates with the ease with which the “absorbent action” of the water-absorbing fabric moves in the direction perpendicular to the skin, and is suitable for evaluating the separation of the skin and the feeling of stickiness.

A double circular knitted fabric was knitted based on the organization chart shown in FIG. 6 using a Fukuhara Seiki circular knitting machine (LPJ type, hook diameter 33 inches, needle density 28G). That is, in FIG. 6, the polyester false twist yarn (84 dtex 72f) is introduced into the yarn feeders F1, F3, F5, and F7 to knit the circular knitted surface, and the polyester false twist yarn (84 dtex 36f) is introduced into the F2, F4, F6, and F8. The back of the circular knitted fabric was knitted. The knitting rate of each yarn was 51.5 mass% for the 84 dtex72f yarn and 48.5 mass% for the 84 dtex36f yarn.
This circular knitted fabric was subjected to scouring, dyeing, and finishing set under the same conditions as in the case of the water-absorbent fabric 1 to obtain a water-absorbent fabric 3.
The density of the water-absorbent fabric 3 was 54 course / inch and 42 wal / inch on the front surface, and 54 course / inch and 42 wal / inch on the back surface. The basis weight was 134 g / m 2 .

［吸水性布帛１〜３の肌離れ性測定例］
吸水性布帛１〜３の各々を直径１１ｃｍの円形に裁断し、その重心の表面のみに（すなわち、吸水性布帛の重心の裏面には至らないように）縫い針を用いて、糸［ポリエステルミシン糸（株式会社クラレ製、クラレエステル「クラフテル２０／４０００ｍ（商品名）」）］を通した。その後、縫い針から糸を外し、糸の両端を結んで全長約１０ｃｍの輪を作った。さらに、この糸の輪にゼムクリップを用いて輪ゴム（共和社製、「オーバンドＮｏ．１６（商品名）」）を直列に繋いだ。各吸水性布帛の裏面（肌側となる面）が、厚さ５ｍｍで２０ｃｍ角のアクリル板に当接するようにして、各吸水性布帛をアクリル板上に載置した。そして、この吸水性布帛に３ｍｌの水を布帛中央部に付与した後、そのままの状態で１分間放置した。その後、輪ゴムを引張試験機［株式会社ティ・エスエンジニアリング製「ＴＥＮＳＩＬＯＮ（品番：ＵＣＴ−５００）」］の上把持部で把持して、垂直方向に引き上げ速度５００ｍｍ／分で引き上げて、引き上げ荷重を読み取った。各吸水性布帛につき、この測定を５回行い、５回の引き上げ荷重の平均値を求めた。この結果は、以下のとおりであった。
・吸水性布帛１・・・３．９ｃＮ
・吸水性布帛２・・・６．７ｃＮ
・吸水性布帛３・・・１７．８ｃＮ [Measurement example of skin releasability of water absorbent fabrics 1 to 3]
Each of the water absorbent fabrics 1 to 3 is cut into a circle having a diameter of 11 cm, and a thread [polyester sewing machine is used only on the surface of the center of gravity (that is, not to reach the back of the center of gravity of the water absorbent fabric). Thread (Kuraray Co., Ltd., Kuraray ester “Kraftel 20/4000 m (trade name)”)] was passed through. Then, the thread was removed from the sewing needle, and both ends of the thread were tied to make a ring with a total length of about 10 cm. Further, a rubber band (“Oband No. 16 (trade name)” manufactured by Kyowa Co., Ltd.) was connected in series using a zem clip to the yarn ring. Each water-absorbing fabric was placed on the acrylic plate so that the back surface (surface on the skin side) of each water-absorbing fabric was in contact with a 20 mm square acrylic plate having a thickness of 5 mm. And after giving 3 ml of water to the fabric center part to this water-absorbing fabric, it was left as it was for 1 minute. Thereafter, the rubber band is gripped by the upper grip portion of a tensile tester [TENSILON (Part No .: UCT-500) manufactured by TS Engineering Co., Ltd.], and is pulled up at a pulling speed of 500 mm / min in the vertical direction. I read it. This measurement was performed 5 times for each water-absorbing fabric, and the average value of the 5 lifting loads was determined. The results were as follows.
-Water-absorbing fabric 1 ... 3.9cN
・ Water absorbent fabric 2 ... 6.7 cN
-Water-absorbing fabric 3 ... 17.8 cN

吸水性布帛１〜３の各々を用いて、スポーツウエアを縫製し、パネラーが着用試験を行ったところ、ベタツキ感が少ないと感じた順序は、吸水性布帛１、吸水性布帛２、吸水性布帛３の順であった。したがって、実施例に係る測定方法は、ベタツキ感と相関していることが分かった。   Sportswear was sewn using each of the water-absorbing fabrics 1 to 3, and the panelist performed a wearing test. The order was 3. Therefore, it was found that the measurement method according to the example correlated with the sticky feeling.
