Description

本発明は繊維製品の弾性力測定装置および該測定装置を用いた測定方法に関し、特に、弾性素材から人体が受ける応力や弾性素材の人体への追従性を測定できるようにするものである。   The present invention relates to an elastic force measuring device for a textile product and a measuring method using the measuring device, and more particularly, to measure the stress applied to a human body from an elastic material and the followability of the elastic material to the human body.

従来、衣類の生地となる繊維製品についての機械的特性の試験方法としては、繊維の伸率、引張り強さ、ヤング率、伸長弾性率の試験方法がある。伸長弾性率は、試料を引張試験機に取り付け、一定の伸び率まで引き伸ばした後、除重し、一定時間放置した後に再び同じように一定伸びまで引き延ばして測定している。（化学繊維の実際知識 第５６頁〜第６０頁）
また、繊維のＪＩＳ規格では、繊維製品の寸法変化測定法ＪＩＳ Ｌ１９０９、天然繊維の引張試験方法ＪＩＳ Ｌ １０６９、ウレタン衣料生地試験方法ＪＩＳ Ｌ １０６６がある。ウレタン衣料生地試験方法ＪＩＳ Ｌ １０６６では、収縮率、剥離強さ、染色堅牢度の試験方法が開示されている。 Conventionally, as a test method for mechanical properties of a textile product used as a fabric of clothing, there are test methods for fiber elongation, tensile strength, Young's modulus, and elongation modulus. The tensile elastic modulus is measured by attaching a sample to a tensile tester, stretching the sample to a certain elongation rate, deweighting it, leaving it for a certain period of time, and then stretching it to a certain elongation again. (Practical knowledge of chemical fiber, pages 56 to 60)
In addition, the fiber JIS standard includes a dimensional change measuring method JIS L1909 for a fiber product, a natural fiber tensile test method JIS L 1069, and a urethane clothing material test method JIS L 1066. Urethane garment fabric test method JIS L 1066 discloses a test method for shrinkage rate, peel strength, and dyeing fastness.

前記のように、従来の繊維製品に関する試験方法には、繊維製品の弾力性の試験方法がなく、かつ、該繊維製品の弾力性を測定する装置も提供されていない。
よって、衣類の生地から人体に負荷される応力や、挙動時における生地の追従性を数値的に測定できる繊維製品の弾性力を測定することは出来なかった。
「化学繊維の実際知識」 第５６頁〜第６０頁 日本化学繊維協会編 発行物：東洋経済新報社 １９９６年１２月２０日 「ＪＩＳハンドブック５４ 繊維」 日本規格協会 As described above, the conventional testing method for textile products does not have a testing method for the elasticity of the textile product, and does not provide an apparatus for measuring the elasticity of the textile product.
Therefore, it was not possible to measure the stress applied to the human body from the clothing fabric and the elastic force of the textile product capable of numerically measuring the fabric followability during behavior.

しかしながら、ブラジャー、ガードル等の肌着を設計する際、目的とする機能を肌着に付加しながら着用感の良いものとするには、素材の各種物性を測定しておく必要がある。例えば、弾性素材を用いる場合、これらの素材の弾力性を測定し、素材が人体に与える応力や挙動時における人体への素材の追従性を把握する必要がある。   However, when designing underwear such as brassiere and girdle, it is necessary to measure various physical properties of the material in order to improve the wearing feeling while adding the intended function to the underwear. For example, when an elastic material is used, it is necessary to measure the elasticity of these materials and grasp the stress that the material gives to the human body and the followability of the material to the human body during behavior.

よって、本発明は、従来提供されていなかった繊維製品、特に弾性素材が人体に負荷する応力、挙動時における追従性を測定できる装置および測定方法を提供することを課題としている。   Therefore, this invention makes it a subject to provide the apparatus and measuring method which can measure the textiles which were not provided conventionally, especially the stress which the elastic material loads to a human body, and the followability | trackability at the time of a behavior.

前記課題を解決するため、本発明は、第一に、圧縮試験機の圧縮ロードセルの先端に圧縮子を取り付けている一方、繊維製品を弛みなく張架する枠材を備えた保持具を設けると共に該保持具を往復作動させる駆動手段とを備え、前記保持具の枠部内に張架された繊維製品を前記圧縮子の先端面に接触配置し、前記駆動手段により保持具を往復作動させることにより、該保持具に張架された繊維製品で前記圧縮子に圧縮力を負荷すると共に負荷を解除し、該圧縮子に発生する応力を応力発生時点からピークを越えて応力消滅時点まで前記圧縮ロードセルにより検出して、前記繊維製品の弾力性を測定する構成としている繊維製品の弾力性測定装置を提供している。   In order to solve the above-mentioned problems, the present invention firstly provides a holder provided with a frame member that stretches a fiber product without slack, while a compressor is attached to the tip of a compression load cell of a compression tester. Drive means for reciprocating the holder, a fiber product stretched in a frame portion of the holder is disposed in contact with the distal end surface of the compressor, and the holder is reciprocated by the drive means. The compression load cell applies a compressive force to the compressor with a fiber product stretched on the holder and releases the load, and the stress generated in the compressor exceeds the peak from the time when the stress occurs to the time when the stress disappears. Is provided, and the elasticity measurement device for the textile product is configured to measure the elasticity of the textile product.

本発明の測定装置において、測定しようとする繊維製品、例えば、肌着とする生地等を、保持具に張架している。其の際、繊維製品は初期位置において前記圧縮子の端面に接触されるだけで圧縮子に圧力を負荷しない設定としている。この状態より繊維製品を保持具と共に前記駆動手段により圧縮子側に移動させると、繊維製品からの押圧荷重により圧縮子に応力が発生し、この応力を圧縮ロードセルで測定している。この測定された圧縮子の応力は、繊維製品からなる生地に負荷が加えられて生地に変形が生じた時に該繊維製品に発生する応力と等価であると見なされる。
また、繊維製品を圧縮子側から後退させて圧縮子に負荷する荷重を減少していき、その際の圧縮子の応力を測定している。この圧縮子の応力は、繊維製品に荷重が負荷されて繊維製品が変形した後に原形に復帰する際の応力と等価であると見なされる。
このように、繊維製品を圧縮子に対して近接、離反させる往復作動させることにより、荷重負荷時に次第に増大していく応力の変移および応力発生時からピークに達するまでの時間と、荷重負荷解除時に次第に減少していく応力の変移とピークから応力消滅までに要する時間とを測定でき、繊維製品の物理的特性である弾性力を測定することができる。 In the measuring apparatus of the present invention, a textile product to be measured, for example, a cloth to be used as an underwear, is stretched around a holder. At that time, the fiber product is set so as not to apply pressure to the compressor only by contacting the end face of the compressor at the initial position. When the fiber product is moved together with the holder to the compressor side from this state, stress is generated in the compressor due to the pressing load from the fiber product, and this stress is measured by a compression load cell. The measured stress of the compressor is considered to be equivalent to the stress generated in the textile product when a load is applied to the textile product and the fabric is deformed.
Also, the load applied to the compressor is decreased by retracting the fiber product from the compressor side, and the stress of the compressor at that time is measured. The stress of the compressor is considered to be equivalent to the stress when the fiber product is restored to its original shape after a load is applied to the fiber product and the fiber product is deformed.
In this way, by reciprocating the fiber product closer to and away from the compressor, the stress gradually increases when the load is applied, the time from when the stress occurs until the peak is reached, and when the load is released. Gradually decreasing stress transition and time from peak to stress disappearance can be measured, and elastic force, which is a physical property of the textile product, can be measured.

具体的には、前記圧縮試験装置の本体に前記圧縮ロードセルを下向きに固定し、該圧縮ロードセルの下端面に前記圧縮子を取り付けている一方、該圧縮子の下面に接触させて前記繊維製品を配置しており、
前記繊維製品を保持する前記保持具は、取付台から立設した円筒部と、該円筒部に外嵌する円環枠あるいはゴム輪からなる環状留材とからなり、前記円筒部の上端面に前記繊維製品を被せて前記環状留材で繊維製品を前記円筒部の外周面に添わせて固定し、前記繊維製品を前記円筒部の外周壁で囲まれた空隙内に弛みなく平面状に張架しており、
前記取付台を前記駆動手段を構成するシリンダのピストン上端に固定し、ピストンを上下方向に繰り返し昇降させる構成としている。 Specifically, the compression load cell is fixed downward on the main body of the compression test apparatus, and the compressor is attached to the lower end surface of the compression load cell, while the fiber product is brought into contact with the lower surface of the compressor. Have placed
The holding tool for holding the textile product is composed of a cylindrical portion erected from a mounting base, and an annular retaining member made of an annular frame or a rubber ring that is fitted around the cylindrical portion, and is formed on the upper end surface of the cylindrical portion. Cover the fiber product and fix the fiber product along the outer peripheral surface of the cylindrical portion with the annular clasp, and stretch the fiber product in a flat space without slack in the space surrounded by the outer peripheral wall of the cylindrical portion. And
The mounting base is fixed to the upper end of the piston of the cylinder constituting the driving means, and the piston is repeatedly raised and lowered in the vertical direction.

前記保持具は円筒部と円環枠あるいはゴム輪から形成すると、円環枠内にしわを発生させることなく繊維製品を張架させることができる。枠内に張架する繊維製品は弛みなく且つ引張せず、繊維製品の原形状で張架している。
駆動手段として空圧、油圧のいずれのシリンダでもよい。また、シリンダの代わりにモータを用い、該モータの回転軸に取り付けたギアにラックを噛み合わせ、該ラックの往復移動により前記取付台を上下作動させてもよい。この作動寸法および作動速度は後述するように所要値に設定している。 When the holder is formed of a cylindrical portion and an annular frame or a rubber ring, the textile product can be stretched without generating wrinkles in the annular frame. The fiber product stretched in the frame is stretched in the original shape of the fiber product without slack and tension.
Either pneumatic or hydraulic cylinders may be used as the driving means. Alternatively, a motor may be used instead of the cylinder, the rack may be meshed with a gear attached to the rotating shaft of the motor, and the mounting base may be moved up and down by reciprocating movement of the rack. The operating dimensions and operating speed are set to required values as will be described later.

本発明は、第二に、前記弾力性測定装置により弾性を有する繊維製品の弾力性測定方法を提供している。該測定方法は、
前記繊維製品により前記圧縮子に押圧荷重を負荷した時に該圧縮子に発生する応力と、応力発生時から応力がピークに達する時間との積からなる荷重負荷時の圧力積分値（Ａ）と、
前記ピークに達した時から応力が消滅するまでの応力と、該ピークに達した時から応力が消滅するまでの時間との積からなる負荷解除時の圧力積分値（Ｂ）を求め、
前記圧力積分値（Ａ）に対する圧力積分値（Ｂ）の比（Ｂ／Ａ）より弾性復帰時の回復率を求めている。 Secondly, the present invention provides a method for measuring elasticity of a textile product having elasticity by the elasticity measuring device. The measurement method is:
A pressure integral value (A) at the time of load application consisting of a product of a stress generated in the compressor when a pressing load is applied to the compressor by the textile product and a time when the stress reaches a peak from the time of the stress generation;
Obtaining a pressure integral value (B) at the time of releasing the load, which is a product of the stress from when the peak is reached until the stress disappears and the time from when the peak is reached until the stress disappears;
The recovery rate at the time of elastic recovery is obtained from the ratio (B / A) of the pressure integral value (B) to the pressure integral value (A).

前記のように、測定装置によれば、繊維製品に荷重が負荷された場合において、繊維製品が荷重により変形する際に発生する応力を測定することができ。即ち、繊維製品が良く伸びる場合には発生する応力が小さく、逆に伸びにくい場合には発生する応力が大きくなる。また、繊維製品に荷重が負荷された後に負荷が解除された際の応力を測定することにより、繊維製品の原形への戻り、即ち、回復力も速度も測定することができる。繊維製品が荷重を負荷されて変形した後、元に戻らない物性である場合には圧縮子に発生した応力は減少する。また、繊維製品の回復力が小さい場合には圧縮子の応力の減少速度は早くなり、弾性回復力が大きい場合には圧縮子の応力の減少速度は遅くなる。
前記した繊維製品に荷重が負荷された時に発生する応力積分値（Ａ）に対して押圧力が解除された時の圧力積分値（Ｂ）が１００％となると、繊維製品に荷重が負荷されて変形した時と同一速度で原形に回復しすることとなる。よって、回復率が１００％に近づく程、負荷が解除された時の回復力、即ち、弾性力が強い繊維製品となる。 As described above, according to the measuring apparatus, when a load is applied to the fiber product, the stress generated when the fiber product is deformed by the load can be measured. That is, when the fiber product stretches well, the generated stress is small, and conversely when it is difficult to stretch, the generated stress increases. Further, by measuring the stress when the load is released after the load is applied to the textile product, the return to the original form of the textile product, that is, the recovery force and the speed can be measured. After the fiber product is deformed by being loaded, the stress generated in the compressor is reduced when the physical properties are not restored. Further, when the recovery force of the fiber product is small, the decrease rate of the stress of the compressor becomes fast, and when the elastic recovery force is large, the decrease rate of the stress of the compressor becomes slow.
When the integrated pressure value (B) when the pressing force is released is 100% with respect to the integrated stress value (A) generated when a load is applied to the above-described fiber product, the load is applied to the fiber product. It will recover to its original shape at the same speed as when it was deformed. Therefore, as the recovery rate approaches 100%, the textile product has a stronger recovery force when the load is released, that is, a stronger elastic force.

前記繊維製品の弾性力の測定は、特に、人間の肌に密着させて使用する繊維製品に測定した場合、該肌着から人体が受ける応力、とくに挙動に肌着が変形した際に人体が受ける応力および、人体の動きに対する肌着の追従性を測定することができる。   The measurement of the elastic force of the textile product, particularly when measured on a textile product used in close contact with human skin, the stress that the human body receives from the underwear, especially the stress that the human body receives when the underwear is deformed due to the behavior and It is possible to measure the followability of the underwear to the movement of the human body.

具体的には、人間の挙動時におけるバスト、ヒップ、腹部等の特定部位の作動寸法および作動面積を予め測定し、該測定値に基づいて、前記駆動手段による往復動作寸法と、前記保持具内に張架される繊維製品の面積とを前記特定部位毎に標準値として設定しておく一方、
前記繊維製品として衣類の素材を用い、該保持具で保持される繊維製品の面積を前記標準値の面積とすると共に、前記駆動手段による繊維製品の作動寸法を前記標準値の作動寸法とし、
前記荷重負荷時の圧力積分値（Ａ）が挙動時における前記特定部位に対して前記繊維製品から負荷される荷重と見なしていると共に、前記回復率は前記繊維製品の人体への追従性の指標としている。 Specifically, the working dimensions and working areas of specific parts such as bust, hips, and abdomen during human behavior are measured in advance, and based on the measured values, the reciprocating movement dimensions by the driving means and the inside of the holder While setting the area of the textile product stretched on the standard value for each specific part,
The material of clothing is used as the textile product, and the area of the textile product held by the holder is the area of the standard value, and the working dimension of the textile product by the driving means is the working dimension of the standard value,
The integrated pressure value (A) when the load is applied is regarded as a load applied from the textile product to the specific part at the time of behavior, and the recovery rate is an index of the followability of the textile product to the human body. It is said.

特に、肌着用の弾性素材からなる繊維製品の弾性力を測定すると、人体に対する肌着の密着性、肌着から受ける圧迫感や締付感、挙動時における人体への肌着の追従性を測定でき、目的とする肌着の機能に応じた弾性素材を選択することができる。
即ち、肌着用となる弾性素材を前記駆動手段により前記予め設定した標準値に応じて駆動して前記圧縮子に荷重を負荷し、
前記荷重負荷時の圧力積分値（Ａ）が前記弾性素材により人体に負荷される荷重と見なしていると共に、前記回復率は前記弾性素材の人体への追従性の指標としている。 In particular, measuring the elasticity of textile products made of elastic materials for underwear can measure the adhesion of the underwear to the human body, the feeling of pressure and tightness received from the underwear, and the follow-up of the underwear to the human body during behavior. It is possible to select an elastic material according to the function of the underwear.
That is, an elastic material to be worn on the skin is driven according to the preset standard value by the driving means to apply a load to the compressor,
The integrated pressure value (A) when the load is applied is regarded as a load applied to the human body by the elastic material, and the recovery rate is an index of the followability of the elastic material to the human body.

前記弾性素材がブラジャーのカップ材とした場合、挙動時、例えば、跳躍時のバストの上下揺れ寸法を測定して標準作動寸法を求めて、駆動手段による弾性素材の往復移動寸法とし、バスト面積の標準寸法を求めておき、保持具に張架する弾性素材の面積としている。 前記標準作動寸法に対応した寸法で前記駆動手段による往復作動させると、バスト挙動時における弾性素材に発生する応力と、弾性素材の回復率を測定できる。該測定値に基づいて弾性素材を選択することにより、目的として機能を有するカップ材を選らぶことができる。
即ち、造形性を目的とするカップ材とする場合には、バスト挙動時に変形しにくく、発生する応力が大きな、所謂、硬い弾性素材が選択される。一方、圧迫感や締付感がすくないカップ材とする場合には、発生する応力が小さい弾性素材が選択される。かつ、バストの挙動に応じて人体にぴったりと追従する動的快適性を有するカップ材とする場合には、発生する応力が小さく且つ回復率の高い弾性素材が選択される。 When the elastic material is a brassiere cup material, the vertical operating dimension of the bust at the time of behavior, for example, jumping is measured to determine the standard operating dimension, and the reciprocating dimension of the elastic material by the driving means is taken. The standard dimension is obtained and the area of the elastic material stretched on the holder. When a reciprocating operation is performed by the driving means with a dimension corresponding to the standard operating dimension, the stress generated in the elastic material during the bust behavior and the recovery rate of the elastic material can be measured. By selecting an elastic material based on the measured value, a cup material having a function can be selected as a purpose.
That is, in the case of a cup material for the purpose of formability, a so-called hard elastic material that does not easily deform during bust behavior and generates a large stress is selected. On the other hand, in the case of a cup material that does not have a feeling of pressure or tightness, an elastic material that generates less stress is selected. In addition, when the cup material has a dynamic comfort that closely follows the human body according to the behavior of the bust, an elastic material that generates a low stress and has a high recovery rate is selected.

前記肌着用の弾性素材では、肌側面が前記圧縮子への接触側となるように前記保持具に取り付けることが好ましい。
例えば、カップ材の場合、該カップ材により荷重を受ける圧縮子が肌に相当することとなるため、肌と接する肌側を圧縮子に接触させると、より正確にバストが弾性素材から受ける応力を測定できる。特に、複数の素材を積層して厚みが大きなカップ材となる場合、カップ材の肌側と外側とでは、発生する応力に異なるため、肌側面を圧縮子に接触させることが好ましい。 In the elastic material for skin wearing, it is preferable that the skin side surface is attached to the holder so that the skin side surface is the contact side to the compressor.
For example, in the case of a cup material, since the compressor that receives a load by the cup material corresponds to the skin, when the skin side that contacts the skin is brought into contact with the compressor, the stress that the bust receives from the elastic material more accurately. It can be measured. Particularly, when a cup material having a large thickness is formed by laminating a plurality of materials, it is preferable that the skin side surface is brought into contact with the compressor because the skin side and the outside of the cup material are different in generated stress.

上述したように、本発明の繊維製品の弾性力測定装置では、従来は測定することができなかった繊維製品の弾性力を測定することができ、この測定値に応じて、目的とする機能を有する繊維製品を正確に選択することができる。
よって、例えば、カップ材、ガードル材において、造形性に主眼をおく場合には応力の大きな繊維製品を選択し、リラックスした着用感を与える場合には応力が小さい繊維製品を選択し、動的快適性を求める場合には回復率が高い繊維製品を選択することができる。 As described above, the fiber product elastic force measuring device of the present invention can measure the elastic force of a fiber product that could not be measured conventionally, and according to the measured value, the target function can be measured. The textile product to have can be selected accurately.
Therefore, for example, in cup materials and girdle materials, select a fiber product with high stress when focusing on formability, and select a fiber product with low stress to give a relaxed wearing feeling. When the property is required, a fiber product having a high recovery rate can be selected.

以下、本発明の実施形態を図面を参照して説明する。
図１および図２は繊維製品の弾性材反発性測定装置を示す。該測定装置は、試料となる弾性素材１を平面円形に保持する保持具２と、該保持具２を支持する取付台３と、該取付台を上下往復作動させる駆動手段となるシリンダ４と、前記保持具２で保持された弾性素材１の上面に接触させる圧縮子５と、該圧縮子５を下端面に取り付けた圧縮ロードセル６と、該圧縮ロードセル６が取り付けられた圧縮試験機本体７とを備えている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 and 2 show an elastic material resilience measuring apparatus for textile products. The measuring apparatus includes a holder 2 that holds the elastic material 1 as a sample in a circular shape, a mounting base 3 that supports the holder 2, a cylinder 4 that serves as a driving means for reciprocating the mounting base, A compressor 5 to be brought into contact with the upper surface of the elastic material 1 held by the holder 2, a compression load cell 6 to which the compressor 5 is attached to a lower end surface, and a compression tester main body 7 to which the compression load cell 6 is attached; It has.

前記保持具２は、取付台３から立設された円筒部２Ａと、該円筒部２Ａに外嵌する円環枠２Ｂとからなり、円筒部２Ａの上端面に弾性素材１を被せ、この状態で弾性素材１を円筒部２Ａの外周面に添わせながら円環枠２Ｂを被せていくことで、円筒部２Ａと円環枠２Ｂとの間に弾性素材１を挟みこむことで、これら円筒部２Ａの外周壁に囲まれた円形状の空隙内に弾性素材１を水平面を保持した状態で張架している。該張架時には弾性素材１に引っ張り力をかけず且つ弛ませない状態としている。   The holder 2 includes a cylindrical portion 2A erected from the mount 3 and an annular frame 2B that fits outside the cylindrical portion 2A. The upper end surface of the cylindrical portion 2A is covered with the elastic material 1 and is in this state. The elastic material 1 is put on the outer peripheral surface of the cylindrical portion 2A and covered with the annular frame 2B, so that the elastic material 1 is sandwiched between the cylindrical portion 2A and the annular frame 2B. The elastic material 1 is stretched in a state of holding a horizontal plane in a circular gap surrounded by the outer peripheral wall of 2A. At the time of the stretching, the elastic material 1 is not pulled or loosened.

前記水平状の基板からなる取付台３の下面中央にシリンダ４の上端面より昇降自在に突出させるピストン４ａの上端面を固定している。該シリンダ４のピストン４ａを上下往復させることにより、取付台３、保持具２、該保持具に張架された弾性素材１を上下往復移動させている。   An upper end surface of a piston 4 a that protrudes up and down from the upper end surface of the cylinder 4 is fixed to the center of the lower surface of the mounting base 3 made of the horizontal substrate. By reciprocating the piston 4a of the cylinder 4 up and down, the mount 3, the holder 2, and the elastic material 1 stretched around the holder are reciprocated up and down.

前記取付台３上の円筒部２Ａの上面に張架した弾性素材１の中央位置の上面に丁度接触するように、前記固定した圧縮試験機保内７の圧縮ロードセル６から垂下する圧縮子５を位置させている。   Position the compressor 5 that hangs down from the compression load cell 6 of the fixed compression tester holder 7 so that it just contacts the upper surface of the central position of the elastic material 1 stretched on the upper surface of the cylindrical portion 2A on the mounting base 3. I am letting.

前記保持具２の内外枠材で囲まれて張架される弾性素材の面積Ｓと、シリンダ４のピストン４ａの上下移動寸法とは、弾性素材を密着される人体の特定部位の挙動時における作動面積と作動寸法に対応させて設定している。この特定部位の作動面積および作動寸法は、前記したように、予め測定し、該測定値に基づいて、特定部位毎に標準値を設定している。   The area S of the elastic material that is surrounded and stretched by the inner and outer frame members of the holder 2 and the vertical movement dimension of the piston 4a of the cylinder 4 are the actions during the behavior of a specific part of the human body that is in close contact with the elastic material. It is set according to the area and operating dimensions. As described above, the working area and the working dimension of the specific part are measured in advance, and a standard value is set for each specific part based on the measured value.

本実施形態では、弾性素材１としてカップ材を用いており、よって、前記保持具２による張架面積を標準値としている約７０ｃｍ2に設定し、シリンダ４のピストン４ａの上下往復移動寸法を標準値の１．５ｃｍに設定している。また、該ピストン４ａは１分間に６０回上下移動させている。 In the present embodiment, a cup material is used as the elastic material 1, and therefore, the tension area by the holder 2 is set to a standard value of about 70 cm 2 , and the vertical reciprocation dimension of the piston 4a of the cylinder 4 is standard. The value is set to 1.5 cm. The piston 4a is moved up and down 60 times per minute.

前記測定装置による測定時に、保持具２に張架した試料のカップ材１は、ピストン４ａの上下往復作動に応じて圧縮子５に押圧荷重を負荷すると共に負荷した荷重を解消する作動を繰り返し行う。
即ち、ピストン４ａを上昇すると、弾性素材１は圧縮子５に押圧荷重を負荷し、該負荷に対して圧縮子５に発生する応力を圧縮ロードセル６により検出している。一方、ピストン４ａを下降させると、弾性素材１による圧縮子５の荷重が次第に減少していき、其の際の圧縮子の応力を測定している。 At the time of measurement by the measuring apparatus, the sample cup material 1 stretched on the holder 2 repeatedly performs the operation of applying a pressing load to the compressor 5 and eliminating the applied load in accordance with the reciprocating operation of the piston 4a. .
That is, when the piston 4 a is raised, the elastic material 1 applies a pressing load to the compressor 5, and the compression load cell 6 detects the stress generated in the compressor 5 with respect to the load. On the other hand, when the piston 4a is lowered, the load on the compressor 5 due to the elastic material 1 gradually decreases, and the stress of the compressor at that time is measured.

前記測定結果は、図３に示すように、縦軸を応力、横軸を時間とすると、応力の増減が山Ｍとなって現れる。
図３（Ａ）は、ピストンを繰り返し上下運動させた間の３回分の山Ｍを示し、山Ｍの前半分部分Ｘはカップ材１が上昇して圧縮子４に押し上げ荷重を作用させた部分に該当し、山Ｍの後後半部分Ｙはカップ材１が加工して圧縮子供４への荷重を解除した部分に該当する。 In the measurement result, as shown in FIG. 3, when the vertical axis is stress and the horizontal axis is time, the increase and decrease of the stress appears as a peak M.
FIG. 3 (A) shows three ridges M while the piston is repeatedly moved up and down, and a front half portion X of the ridge M is a portion where the cup material 1 is lifted and a pushing load is applied to the compressor 4. The rear half portion Y of the mountain M corresponds to a portion where the cup material 1 is processed and the load on the compressed child 4 is released.

図３（Ｂ）の前半部分Ｘの圧力積分値に対して、後半部分Ｙの圧力積分値が１００％、即ち、前半部分Ｘと後半部分Ｙとが左右対称となると、変形挙動に対して逆の変形挙動をとりながら同一速度で原形に回復していることを表す。よって、回復率が１００％に近づく程、負荷が解除された時の回復力が強いことを意味する。   When the integrated pressure value of the second half Y is 100% with respect to the integrated pressure value of the first half X in FIG. 3B, that is, when the first half X and the second half Y are symmetrical, the deformation behavior is reversed. It shows that the original shape is recovered at the same speed while taking the deformation behavior of. Therefore, the closer the recovery rate is to 100%, the stronger the resilience when the load is released.

前記前半部分Ｘの応力積分値は、縦軸で示す負荷に応じて発生する応力と、横軸で示す応力発生時から応力がピークに達する時間との積から応力積分値が求められる。後半部分Ｙの応力積分値は応力がピークに達した時から応力が無くなるまでの時間と応力との積から求められる。
前記した前半部分Ｘの応力積分値が大きくなると、カップ材に荷重が負荷された時の応力が大きく、バストに対する圧迫感や締付感が強くなる。逆に応力積分値が小さくなると、負荷に対して発生する応力が少なく、バストの動きに対して変形して追従することとなる。 The stress integral value of the first half portion X is obtained from the product of the stress generated according to the load indicated by the vertical axis and the time when the stress reaches the peak from the time of the stress indicated by the horizontal axis. The stress integral value in the latter half Y is obtained from the product of the time from when the stress reaches the peak until the stress disappears and the stress.
When the stress integral value of the first half portion X described above increases, the stress when a load is applied to the cup material increases, and the feeling of pressure and tightness against the bust increases. On the contrary, when the stress integrated value is small, the stress generated with respect to the load is small, and the bust movement is deformed and followed.

「実施例」
図４に示す４種類のカップ材となる弾性素材を用意して、予め設定したバストにおける標準値に基づいて、前記弾性素材に発生する応力と、回復率とを測定した。 "Example"
Four types of elastic materials as cup materials shown in FIG. 4 were prepared, and the stress generated in the elastic material and the recovery rate were measured based on a standard value in a preset bust.

カップ材Ａは造形美を付与することを主たる機能とする代表的なカップ材で、肌側は不織布の肌側面に天竺素材、外面側にトリコット素材を接着剤でラミネートした素材、外側はエンブロイダリー（刺繍）レースからなる。
カップ材Ｂは、バストが動かない状態での静的快適性を追求したカップ材で、肌側は低反発性の発泡ウレタンの表裏両面にトリコット素材をラミネートした素材、外側はエンブロイダリー（刺繍）レースからなる。
カップ材Ｃ、Ｄは、動的快適性を追求したカップ材である。
カップ材Ｃは、肌側はポリウレタン弾性糸を含むベア天竺素材、中間は低反発性の発泡ウレタンの両面にベア天竺素材を接着剤でラミネートした素材、外側は縦横方向に伸びるＴ／Ｗラッセルからなる。
カップ材Ｄは、肌側は低反発性の発泡ウレタンの表裏両面にベア天竺素材を接着剤でラミネートした素材、外側はストレッチラッセルレースからなる。 The cup material A is a typical cup material whose main function is to impart modeling beauty. The skin side is a non-woven skin side surface made of a tengu material, the outer side is laminated with a tricot material with an adhesive, and the outer side is an embroidery. Consists of dally (embroidery) lace.
Cup material B is a cup material that pursues static comfort in a state where the bust does not move. The skin side is made of low-rebound foamed urethane with a tricot material laminated on both sides, and the outside is an embroidery (embroidery) ) Consists of races.
Cup materials C and D are cup materials pursuing dynamic comfort.
The cup material C is made of a bare sheet material containing polyurethane elastic yarn on the skin side, a material in which the middle is laminated with bare adhesive material on both sides of low-resilience foamed urethane, and the outside is a T / W Russell that extends vertically and horizontally. Become.
The cup material D is made of a material obtained by laminating a bare sheet material with an adhesive on both the front and back surfaces of a low-resilience urethane foam on the skin side, and a stretch raschel lace on the outside.

前記４種類のカップ材Ａ〜Ｄを、夫々図１に示す測定装置の保持具２内に張架した。張架面積は約７０ｃｍ2とした。其の際、カップ材Ａ〜Ｄは肌側を圧縮子への接触側として張架した。
ついで、シリンダ４のピストン４ａを１．５ｃｍで上下往復作動し、該上下往復回数は１分間に６０回とした。各カップ材Ａ〜Ｄについてそれぞれ複数回の測定を行った。
各カップ材Ａ〜Ｄの平均測定値を下記の表１に示す。 The four types of cup materials A to D were stretched in the holder 2 of the measuring apparatus shown in FIG. The stretched area was about 70 cm 2 . At that time, the cup materials A to D were stretched with the skin side as the contact side to the compressor.
Subsequently, the piston 4a of the cylinder 4 was reciprocated up and down at 1.5 cm, and the number of reciprocations was 60 times per minute. Each cup material A to D was measured several times.
The average measured values of the cup materials A to D are shown in Table 1 below.

図５は測定結果のグラフを示し、縦軸が圧縮子に発生した応力、横軸が時間経過を示す。 該グラフに表されているように、発生した応力から見ると、造形美を追求するカップ材Ａはバストの動きに応じて発生する応力が大きく、バストの動きに追従しにくいものであることが確認できた。
静的快適性を追求するカップ材Ｂも応力が比較的大きく、バストの動きに対する追従性が劣ることが分かる。
これに対して、動的快適性を追求したカップ材Ｃ、Ｄは応力が小さく、バストの動きに追従しやすいものであることが認められる。
バストから負荷される荷重により発生する応力は１０００ｇｆを越えると、圧迫感が比較的大きくなるため、動的快適性を求めるカップ材では応力が１０００ｇｆ以下とすることが好ましいことも解明できた。
なお、前記応力が３００ｇｆ未満であると、カップ材としてバストの保持性がほとんどなるなることも確認できた。 FIG. 5 shows a graph of the measurement results, in which the vertical axis indicates the stress generated in the compressor and the horizontal axis indicates the passage of time. As shown in the graph, when viewed from the generated stress, the cup material A pursuing modeling beauty has a large stress generated according to the movement of the bust, and it is difficult to follow the movement of the bust. It could be confirmed.
It can be seen that the cup material B pursuing static comfort is also relatively large in stress and inferior in the ability to follow the movement of the bust.
On the other hand, it is recognized that the cup materials C and D pursuing dynamic comfort have a small stress and can easily follow the movement of the bust.
When the stress generated by the load applied from the bust exceeds 1000 gf, the feeling of pressure becomes relatively large. Therefore, it was also clarified that the stress is preferably 1000 gf or less in the cup material for which dynamic comfort is required.
It has also been confirmed that when the stress is less than 300 gf, the bust retainability becomes almost as a cup material.

前記図５のグラフより、各カップ材Ａ〜Ｄの前記山Ｍの前半部分Ｘの圧力積分値（Ａ）と後半部分Ｙの圧力積分値（Ｂ）を求めた。かつ、圧力積分値（Ａ）と（Ｂ）とから回復率（Ｂ／Ａ）を求めた。その結果を下記の表１に示す。
該表１には、カップ材Ａ〜Ｄの外面側を圧縮子に接触させた場合の測定結果も併記した。 From the graph of FIG. 5, the pressure integral value (A) of the first half portion X and the pressure integral value (B) of the second half portion Y of each of the cup materials A to D were obtained. And recovery rate (B / A) was calculated | required from pressure integrated value (A) and (B). The results are shown in Table 1 below.
Table 1 also shows the measurement results when the outer surfaces of the cup materials A to D are brought into contact with the compressor.

Figure 2005291925
Figure 2005291925

表１に示されるように、カップ材Ａ〜Ｄにおける前半部分の圧力積分値はＡ＞Ｂ＞Ｃ＞Ｄの関係となり、造形美を追求するためのカップ材Ａの圧力積分値が最も大きかった。このことから、バスト挙動時にもカップ材Ａは伸びにくいと共に変形しにくく、肌に相当する側の圧縮子に最も大きな応力がかかることが確認できた。よって、カップ材Ａは変形しにくいためバスト造形性に優れているが、バスト挙動時には圧迫力、締付力が大きくなる素材であることが確認できた。
静的快適性を追求するカップ材Ｂは、カップ材Ａよりも圧力積分値が小さいことから、カップ材Ａよりはバストが動いた時に変形して伸びが生じるが、カップ材Ｃ、Ｄと比較して前半部分の圧力積分値が大きいことから、伸びや変形がすくなく、カップ材Ａよりは圧迫感が小さいが、カップ材Ｃ，Ｄよりはバスト保形性を備えていることが分かる。
カップ材Ｃ，Ｄは前半部分の圧力積分値が最も小さいことより、バスト挙動時にバストの動きに応じて伸びると共に変形し、バストの動きと略一体となって動くものであることが確認できた。 As shown in Table 1, the pressure integral value of the first half part in the cup materials A to D has a relationship of A>B>C> D, and the pressure integral value of the cup material A for pursuing the beauty of modeling was the largest. . From this, it was confirmed that the cup material A was not easily stretched and deformed even during bust behavior, and the greatest stress was applied to the compressor on the side corresponding to the skin. Therefore, although it is hard to deform | transform, the cup material A is excellent in bust shaping | molding property, but it has confirmed that it was a raw material with which a compression force and a clamping force become large at the time of bust behavior.
Cup material B pursuing static comfort has a smaller integrated pressure value than cup material A, so it deforms and stretches when the bust moves than cup material A. Compared to cup materials C and D And since the pressure integral value of the first half part is large, it is understood that it is less stretched and deformed and has a feeling of pressure smaller than that of the cup material A, but has a bust shape retaining property than that of the cup materials C and D.
It was confirmed that the cup materials C and D were expanded and deformed according to the movement of the bust at the time of the bust behavior because the pressure integral value of the first half portion was the smallest, and moved substantially integrally with the movement of the bust. .

よって、前記バスト挙動による弾性素材の変形により肌に負荷される応力積分値は、３０００未満となると、カップ材ではバストの造形性、保形性が劣ることとなる。一方、２５０００を越えると常時圧迫感や締付感を感じることとなり、２５０００以下で１３０００を越えると締め付け感は余りないが、バストが挙動時には比較的追従しにくくなる。よって、バストの動きに抵抗なく追従しながらバストの保形性を保つには圧力積分値が３０００以上１３０００以下が好ましい。   Therefore, when the stress integral value applied to the skin due to the deformation of the elastic material due to the bust behavior is less than 3000, the cup material is inferior in bust moldability and shape retention. On the other hand, if it exceeds 25000, a feeling of pressure and tightening will be felt at all times, and if it exceeds 15000 and less than 13000, the feeling of tightening will not be much, but it will be relatively difficult to follow when the bust is moving. Therefore, in order to maintain the shape retention of the bust while following the movement of the bust without resistance, the pressure integral value is preferably 3000 to 13000.

表１に記載した肌側を圧縮子に接触させた場合の前半部分の圧力積分値（Ａ）と回復率との関係を図６のグラフに示す。
前記したように、回復率は１００％に近づく程、バストの変形に応じて伸びたり変形したりするカップ材が、元の原形に回復する力が強いために、動的快適性が優れたものとなる。
カップ材Ａ〜Ｄの回復率は、Ｃ＞Ａ＞Ｄ＞Ｂの順序となっており、カップ材Ａの回復率が最大であるため、最もバスト挙動に対する追従性がよく、人体と一体となって動く素材であることが確認できた。これに対して回復率が最も低いカップ材Ｂは挙動追従性が遅いため、静的快適性は優れたものであるが動的快適性の点では劣ることもわかった。 The graph of FIG. 6 shows the relationship between the pressure integral value (A) of the first half and the recovery rate when the skin side described in Table 1 is brought into contact with the compressor.
As described above, as the recovery rate approaches 100%, the cup material that stretches or deforms according to the deformation of the bust has a strong force to recover to the original shape, so the dynamic comfort is excellent It becomes.
The recovery rates of the cup materials A to D are in the order of C>A>D> B. Since the recovery rate of the cup material A is the maximum, the followability with respect to the bust behavior is the best and is integrated with the human body. It was confirmed that the material was moving. On the other hand, it was also found that the cup material B having the lowest recovery rate has a low behavior followability, so that the static comfort is excellent but the dynamic comfort is inferior.

カップ材Ａ〜Ｄの肌側を圧縮子に接触させた場合と、外側を圧縮子に接触させた場合とでは、圧力積分値（Ａ）（Ｂ）、回復率も相違するが、カップ材Ａ〜Ｄの圧力積分値の大きさの順序、回復率の順序は同じである。
前記各カップ材の肌側と外側とを圧縮子に接触させた場合における圧力積分値と回復率の相違は、それぞれ下記の理由に因ると判断されるが、このような測定結果の相違がでることより、本発明の測定装置の測定精度が高いものであることが確認出来た。 Although the pressure integrated values (A) and (B) and the recovery rate are different between the case where the skin side of the cup materials A to D is brought into contact with the compressor and the case where the outside is brought into contact with the compressor, the cup material A The order of the magnitudes of the integrated pressure values of ~ D and the order of the recovery rates are the same.
The difference between the pressure integral value and the recovery rate when the skin side and the outside of each cup material are in contact with the compressor is determined to be due to the following reasons, respectively, As a result, it was confirmed that the measurement accuracy of the measurement apparatus of the present invention was high.

即ち、カップ材Ａでは、外側の薄くて伸びないレースよりも、肌側のやや厚みのある不織布がクッションとなるため、外側面よりも肌側面の方が応力が低くなった。
カップ材Ｂでは、硬さは略近い数値であったが、肌側の素材は低反発性クッションになっているため、回復率はカップ材Ｃ，Ｄより低かった。
カップ材Ｃでは、外側のみならず、肌側にもポリウレタンを多く含む弾力効果が発揮できる素材を使用しているため、肌側の回復力が高かった。
カップ材Ｄは肌側は低反発性クッションであり、ベア天竺で伸びるようにしてはいるが、外側よりも弾力効果自体が少ないため、回復率はカップ材Ｃより低く出た。
カップ材Ｄでは、 That is, in the cup material A, since the non-stretched nonwoven fabric on the skin side is a cushion rather than the outer thin and non-extending lace, the stress is lower on the skin side surface than on the outer side surface.
In the cup material B, the hardness was a substantially close numerical value, but the recovery rate was lower than that of the cup materials C and D because the material on the skin side was a low resilience cushion.
In the cup material C, since the material which can exhibit the elastic effect which contains many polyurethanes not only on the outside but also on the skin side is used, the resilience on the skin side was high.
Although the cup material D is a low resilience cushion on the skin side and is stretched by a bare tengu, the recovery effect is lower than that of the cup material C because the elastic effect itself is less than the outside.
In cup material D,

前記した通り、バストの動きにより荷重が負荷される前半部分の応力積分値が小さいほどバストの動きに追従して変形し、また、負荷が除去されていく後半部分の応力積分値が前半部分の応力積分値に近似する程、回復率が高くなり、変形後の原形復帰力が強く、カップ材として場合に動的快適性が優れたものとなる。
図６のグラフに示す通り、本発明のカップ材Ｃ，Ｄは（ｃ、ｄ）の領域にあり、応力積分値は３０００〜１３０００の範囲で、回復率は８５％以上に達している。よって、応力積分値と回復率との両方から、最も動的快適性が優れたカップ材と言える。
これに対して、カップ材Ａは（ａ）の領域にあり、応力積分値が２８０００〜４１０００の範囲であるため、バストへの追従性が劣り、かつ、回復率もカップ材Ｃより劣っていた。
また、静的快適性を追求したカップ材Ｂは（ｂ）の領域にあり、応力積分値が動的快適性から求められる１３０００を越えており、回復率もカップ材Ｄ，Ｃより劣っていた。 As described above, the smaller the stress integral value of the first half portion where the load is applied by the movement of the bust, the smaller the stress integral value of the first half portion follows the movement of the bust. The closer to the stress integral value, the higher the recovery rate, the stronger the original restoring force after deformation, and the better the dynamic comfort when used as a cup material.
As shown in the graph of FIG. 6, the cup materials C and D of the present invention are in the region (c, d), the stress integral value is in the range of 3000 to 13000, and the recovery rate reaches 85% or more. Therefore, it can be said that the cup material has the most excellent dynamic comfort from both the stress integral value and the recovery rate.
On the other hand, since the cup material A is in the region (a) and the stress integral value is in the range of 28000 to 41000, the followability to the bust is inferior and the recovery rate is also inferior to the cup material C. .
Further, the cup material B pursuing static comfort is in the region (b), the stress integral value exceeds 13,000 required from the dynamic comfort, and the recovery rate is also inferior to the cup materials D and C. .

前記弾性素材の反発測定試験から、圧力積分値が３０００〜１３０００の範囲内で、かつ、該圧力積分値の範囲内における回復率が８５％〜１００％である弾性素材を備えているカップ材が、動的快適性に優れたカップ材となることを究明され、動的快適性を求めるブラジャーのカップ材として適したものであることが測定試験により実証された。
一方、バスト造形性を求めるブラジャーのカップ材としてはカップ材Ａが好ましい弾力性を備え、静的快適性を求めるブラジャーのカップ材としてはカップ材Ｂが好ましい弾力性を備えることも実証できた。 From the rebound measurement test of the elastic material, a cup material comprising an elastic material having a pressure integral value in the range of 3000 to 13000 and a recovery rate in the range of the pressure integral value of 85% to 100%. It was determined that the cup material was excellent in dynamic comfort, and it was proved by a measurement test that it was suitable as a cup material for a brassiere that requires dynamic comfort.
On the other hand, it was also proved that the cup material A has preferable elasticity as the cup material of the brassiere that requires bust moldability, and the cup material B has preferable elasticity as the cup material of the brassiere that requires static comfort.

前記実施例ではカップ材の弾力性の測定を行ったが、ガードルの腹部押さえ布、臀部押し上げ布等の素材となる弾性素材に関しても同様な弾力性測定を行うことにより、目的とする機能を有する素材を的確に選択することができる。   In the above embodiment, the elasticity of the cup material was measured. However, the elastic material used as a material for the girdle abdomen presser cloth, buttocks push-up cloth, etc. has the intended function by measuring the same elasticity. The material can be selected accurately.

本発明の弾力性測定装置では、肌着の生地のみに限らず、衣類の弾力性も測定したい箇所を測定装置の保持具内に張架できれば、簡単に、該衣類が人体に対して負荷する応力およびその反発力を測定することができる。   In the elasticity measuring device of the present invention, the stress applied to the human body can be easily applied to the human body as long as the location where the elasticity of the clothing is desired to be measured can be stretched in the holder of the measuring device. And its repulsive force can be measured.
