Description
本発明は、弾性糸を含有する織物において、伸長時瞬間的に温度が上昇する弾性織物を提供するものである。 The present invention provides an elastic woven fabric containing an elastic yarn whose temperature rises instantaneously when stretched.
従来より、保温衣服等、着用時に温度が上昇する衣服として、セルロース等の吸湿発熱繊維を混合した布帛からなる衣服を製造し、着用時の人体からの不感蒸泄や発汗により発熱させる衣服が知られている（例えば、下記特許文献１参照）。しかし、これらの吸湿発熱繊維では、繊維の吸湿量が飽和に達すればそれ以上発熱することは無く、発熱時間が短いばかりでなく、吸湿量が飽和に達した後は、繊維中の水分により冷感を感じることさえあった。
さらに、吸湿発熱以外の発熱衣服として、面状発熱や発熱繊維など、ヒーターを組み込むことも可能であるが、いずれも電気により発熱するもので、衣服とした際は重くなり、電極も必要で動きにくい衣服となる。
Conventionally, clothes that are made of a fabric mixed with moisture-absorbing heat-generating fibers such as cellulose are manufactured as heat-insulating clothes and other clothes whose temperature rises when worn, and heat is generated by insensitive excretion and sweating from the human body when worn. (For example, refer to Patent Document 1 below). However, these moisture-absorbing heat-generating fibers do not generate any further heat when the fiber's moisture absorption reaches saturation, not only the heat generation time is short, but also after moisture absorption reaches saturation, the moisture absorption in the fiber causes cooling. There was even a feeling.
In addition, it is possible to incorporate heaters such as sheet-like heat generation and heat generation fiber as heat generation clothes other than moisture absorption heat generation, but all of them generate heat by electricity, they become heavy when used as clothes, move with electrodes necessary It becomes difficult clothes.
また、下記特許文献２には、弾性糸を含有する編地において、伸張時発熱する編地の提案もなされているが、編地ではハリ、コシといった織物特有の風合いが得られず、これらの風合いが要求される衣服やサポーター分野への展開は不可能であった。
この様に、現在、着用時温度が上昇し、また、動きやすくて軽く、着用運動している限り持続的に発熱し、かつ、ハリ、コシといった良好な風合いを有する織物は見られない。
Patent Document 2 below also proposes a knitted fabric that generates heat when stretched in a knitted fabric containing an elastic yarn, but the knitted fabric does not have a texture specific to fabrics such as elasticity and stiffness. It was impossible to develop into clothing and supporter fields that require a texture.
Thus, at present, there are no woven fabrics that have a high temperature when worn, are easy to move, light, generate heat continuously as long as they are wearing, and have a good texture such as firmness and stiffness.
本発明の目的は、弾性糸を含有する布帛において、伸長時瞬間的に温度が上昇し、伸縮を繰り返しても持続的に伸長時発熱し、ハリ、コシのある良好な風合いを有する織物を提供することであり、さらにこの織物を利用して保温性と伸長部位の筋肉や関節を暖めることによる怪我の防止や筋肉および脂肪燃焼効果も期待できる衣料製品を提供することである。 An object of the present invention is to provide a woven fabric that has a good texture with firmness and stiffness, in a fabric containing elastic yarns, whose temperature rises instantaneously when stretched and generates heat continuously when stretched repeatedly. Furthermore, it is to provide a clothing product that can be used for the heat retention, prevention of injury by warming muscles and joints at the stretched part, and muscle and fat burning effect.
本発明者は、上記目的を達成するため鋭意検討の結果、非弾性糸と弾性糸とからなる織物からなり、伸長時の瞬間発熱温度が１．０℃以上であることを特徴とする織物により上記目的が達成出来ることを見出し、本発明に至った。 As a result of intensive studies to achieve the above object, the present inventor has made a woven fabric composed of an inelastic yarn and an elastic yarn, and has an instantaneous heat generation temperature at the time of elongation of 1.0 ° C. or higher.

以下、本発明について詳細に説明する。
本発明の弾性織物は、非弾性糸と弾性糸とからなる織物であって、織物伸長時の瞬間発熱温度が１．０℃以上であることを特徴とする。
本発明における瞬間発熱温度とは、伸縮以外に外部からのエネルギー供給を受けない条件下で織物を１００％伸長し、次いで緩和してもとの長さに戻す工程を１回とする繰り返し伸縮を、１００回行った後、１００回目の６０〜８０％伸長時の織物温度をサーモグラフィで測定し、試験開始前の織物温度との差から算出された値である。なお、温度を測定する際の伸長量の設定は９．８Ｎ荷重下での織物伸度と同じとし、９．８Ｎ荷重下での織物伸度が８０％以上の場合は伸長量が８０％の温度を測定する。
Hereinafter, the present invention will be described in detail.
The elastic woven fabric of the present invention is a woven fabric composed of inelastic yarns and elastic yarns, and is characterized in that an instantaneous heat generation temperature when the woven fabric is stretched is 1.0 ° C. or higher.
In the present invention, the instantaneous heat generation temperature means that the fabric is stretched 100% under conditions that do not receive external energy supply other than stretching, and then the process of returning to the original length once relaxed is repeated stretching and stretching. After 100 times, the fabric temperature at 60 to 80% elongation at the 100th time is measured by thermography, and is a value calculated from the difference from the fabric temperature before the start of the test. In addition, the setting of the elongation amount when measuring the temperature is the same as the fabric elongation under a 9.8N load, and when the fabric elongation under a 9.8N load is 80% or more, the elongation amount is 80%. Measure the temperature.
１００回目の６０〜８０％伸長時の織物温度が試験開始前より高くなれば、瞬間発熱していることを示し、本発明の弾性織物はこの方法により測定した瞬間発熱温度が、１．０℃以上あることが必要である。１．０℃未満の瞬間発熱温度では、ほとんど発熱を感じられず、発明の目的が達成されない。好ましくは瞬間発熱温度が１．５℃以上である。瞬間発熱温度は高いほど好適であり、人体に悪影響を与えない範囲であれば上限は特に限定されないが、瞬間発熱温度を高くするために弾性糸含有量が多くなりすぎると織物がハイパワーとなって衣服として動き難くなる。従って１０．０℃以下であることが好ましい。なお、発熱温度の測定については、実施例にて具体的に示す。 If the fabric temperature at the time of 60 to 80% elongation at the 100th time becomes higher than before the start of the test, it indicates that instantaneous heat is generated, and the elastic fabric of the present invention has an instantaneous heat generation temperature measured by this method of 1.0 ° C. That is necessary. At an instantaneous heat generation temperature of less than 1.0 ° C., almost no heat generation is felt, and the object of the invention is not achieved. Preferably, the instantaneous heat generation temperature is 1.5 ° C. or higher. The higher the instantaneous heat generation temperature, the better. The upper limit is not particularly limited as long as it does not adversely affect the human body, but if the elastic yarn content becomes too high to increase the instantaneous heat generation temperature, the fabric becomes high power. It becomes difficult to move as clothes. Therefore, it is preferable that it is 10.0 degrees C or less. In addition, about the measurement of exothermic temperature, it shows concretely in an Example.
本発明の弾性織物において、伸長時の瞬間発熱温度が１．０℃以上とするには、織物中に弾性糸が４０〜１５０ｇ／ｍ2含有されていることが好ましい。弾性糸を多く含有するほど発熱温度が高くなり、５０ｇ／ｍ2以上含有していることがさらに好ましい。弾性糸の含有量が多くなり過ぎると織物重量が増し、また、織物がハイパワーとなって動き難くなるため、１５０ｇ／ｍ2以下が好ましい。なお、伸長時発熱する方向は、経方向、緯方向いずれか一方向のみでもよく、この場合、伸長時発熱する方向に衣服がよく伸びる方向に型入れすれば着用運動時に暖かい衣服となる。無論経緯両方向に伸長する織物でもよく、この場合、伸長方向にとらわれず型入れ可能となる。 In the elastic woven fabric of the present invention, it is preferable that the elastic yarn is contained in an amount of 40 to 150 g / m 2 so that the instantaneous heat generation temperature at the time of elongation is 1.0 ° C. or higher. The more elastic yarn is contained, the higher the exothermic temperature becomes, and more preferably 50 g / m 2 or more is contained. If the elastic yarn content is too high, the weight of the fabric increases, and the fabric becomes high power and difficult to move, so 150 g / m 2 or less is preferable. Note that the direction of heat generation during extension may be only one of the warp direction and the weft direction. In this case, if the mold is placed in a direction in which the clothes are well extended in the direction of heat generation during extension, the clothes become warm during the wearing exercise. Of course, a woven fabric that extends in both directions may be used, and in this case, it is possible to insert a mold without being bound by the extending direction.
本発明の弾性織物の発熱効果についてさらに検討した結果、弾性織物の伸度による影響も大きく、９．８Ｎ荷重下の経伸度および／または緯伸度が６０〜１５０％であることが好ましい。９．８Ｎ荷重下の伸度が６０％未満では、伸縮性が乏しく、着用時に突っ張り感を感じる不快な衣服となる。一方、１５０％より大きい場合は、伸長時十分に発熱しない衣服となる。通常の弾性糸を含有するストレッチ織物の伸度が２０〜５０％程度であるのに対し、上記伸度は多めであるが、この伸度調整は、弾性糸の繊度調整、弾性糸の打ち込み本数調整、織物中の弾性糸の伸長率等により可能で、特に、染色加工仕上時の追い込み量調整が重要である。なお、織物の伸度は、経、緯少なくともどちらか一方向が９．８Ｎ荷重下伸度を６０〜１５０％とする必要があり、特に限定されないが低伸度である織物の方向を衣服着用動作時によく伸長する方向にあわせて製造すれば、伸長時発熱効果が発揮されやすい衣服となる。勿論、経緯両方向とも上記範囲に入っていてもよい。また、弾性織物の伸度測定は実施例に記載する方法により行うが、衣服の伸度が部分的に異なり高伸度部と低伸度部が混在した衣服であり、低伸度部の長さがサンプリング長に不足している場合は、低伸度部を中心にして高伸度部を含めて織物をサンプリングして測定する。 As a result of further examination of the heat generation effect of the elastic fabric of the present invention, the influence of the elongation of the elastic fabric is large, and the warp elongation and / or weft elongation under a 9.8 N load is preferably 60 to 150%. If the elongation under a 9.8N load is less than 60%, the stretchability is poor, and an unpleasant garment that feels tense when worn is formed. On the other hand, if it is larger than 150%, the clothes do not generate enough heat when stretched. While the elongation of a stretch fabric containing ordinary elastic yarn is about 20 to 50%, the elongation is higher, but this elongation adjustment is performed by adjusting the fineness of the elastic yarn and the number of elastic yarns to be driven. This is possible depending on the adjustment, the elongation rate of the elastic yarn in the woven fabric, etc. Particularly, it is important to adjust the driving amount at the finishing of the dyeing process. It should be noted that the elongation of the woven fabric needs to be 9.8N under 60% to 150% in at least one direction of warp and weft, and is not particularly limited, but the direction of the woven fabric having a low elongation is not worn. If it is manufactured according to the direction in which it is often stretched during operation, it becomes a garment that easily exhibits a heat generation effect when stretched. Of course, both directions may be within the above range. In addition, the elongation of elastic fabric is measured by the method described in the examples, but the garment is partially different in the elongation of the garment and is a mixture of a high elongation part and a low elongation part. If the sampling length is insufficient, the fabric is sampled and measured including the high elongation portion around the low elongation portion.
本発明の弾性織物に用いられる弾性糸の繊度は、１００〜５００ｄｔｅｘであることが好ましく、より好ましくは１１０〜３５０ｄｔｅｘである。弾性糸が太くなる程、伸長時の発熱効果を発揮でき、１００ｄｔｅｘより細いと発熱効果が小さい。一方、５００ｄｔｅｘより太いと伸縮力が大きくなりすぎ、着用して突っ張り感が強く動き難く不快な衣服となる。繊度の異なる複数の弾性糸を使用する場合も、弾性糸の繊度が上記範囲であることが好ましい。 The fineness of the elastic yarn used in the elastic fabric of the present invention is preferably 100 to 500 dtex, more preferably 110 to 350 dtex. As the elastic yarn becomes thicker, the heat generation effect at the time of elongation can be exhibited, and when it is thinner than 100 dtex, the heat generation effect is small. On the other hand, if it is thicker than 500 dtex, the stretch force becomes too large, and it becomes unpleasant clothes that are worn and have a strong feeling of tension and are difficult to move. Even when a plurality of elastic yarns having different finenesses are used, the fineness of the elastic yarns is preferably in the above range.
また、本発明の弾性織物の弾性糸の打ち込み本数は、経、緯とも８〜１４本／１０ｍｍであることが好ましく、打ちこみ本数が８本／１０ｍｍ未満では十分な発熱効果が得られない。一方、１４本／１０ｍｍより多くなると、織物がハイパワーとなって動き難くなる。好ましくは９〜１３本／ｍｍである。 The number of elastic yarns of the elastic woven fabric of the present invention is preferably 8 to 14/10 mm for both the warp and the weft. If the number of punches is less than 8/10 mm, a sufficient heat generation effect cannot be obtained. On the other hand, if it exceeds 14 / 10mm, the fabric becomes high power and it becomes difficult to move. Preferably, it is 9-13 pieces / mm.
本発明の弾性織物は、織物の長さ（Ａ）に対する織物から抜き出した弾性糸の長さ（Ｂ：０．９８Ｎ荷重下での長さ）の比（Ｂ／Ａ）も重要である。通常の弾性糸を含有するストレッチ織物では、織物から抜き出した弾性糸の長さは織物の長さに対する織物から抜き出した弾性糸の長さの比は１．１〜１．５程度であるが、本発明の弾性織物では経、緯ともに１．７〜３．０が好ましい。織物の長さに対する織物から抜き出した弾性糸の長さの比が１．７未満では伸びにくい衣服となり動き難く不快で、３．０より大きい衣服では着用時に発熱し難い衣服となる。従って、織物の長さに対する織物から抜き出した弾性糸の長さの比が１．７〜３．０になるように織物設計することが好ましく、さらに好ましくは１．９〜２．７となるように織物設計する。
なお、織物の長さに対する織物から抜き出した弾性糸の長さの比の測定方法は実施例にて示す。
In the elastic fabric of the present invention, the ratio (B / A) of the length of elastic yarn extracted from the fabric (B: length under a load of 0.98 N) to the length (A) of the fabric is also important. In the stretch fabric containing ordinary elastic yarns, the ratio of the length of the elastic yarn extracted from the fabric to the length of the elastic yarn extracted from the fabric is about 1.1 to 1.5, In the elastic fabric of the present invention, both warp and weft are preferably 1.7 to 3.0. If the ratio of the length of the elastic yarn extracted from the woven fabric to the length of the woven fabric is less than 1.7, the garment is difficult to stretch and uncomfortable to move, while the garment larger than 3.0 is difficult to generate heat when worn. Accordingly, it is preferable to design the fabric so that the ratio of the length of the elastic yarn extracted from the fabric to the length of the fabric is 1.7 to 3.0, and more preferably 1.9 to 2.7. Design the fabric.
A method for measuring the ratio of the length of the elastic yarn extracted from the fabric to the length of the fabric is shown in the examples.
本発明の弾性織物を構成する弾性糸としては、ポリウレタン系、ポリエーテルエステル系の弾性糸で、例えばポリウレタン系弾性糸では、乾式紡糸又は溶融紡糸したものが使用でき、ポリマーや紡糸方法には特に限定されない。弾性糸の破断伸度は４００％〜１０００％程度が好ましく、かつ、伸縮性に優れ、染色加工時のプレセット工程で通常処理温度の１８０℃近辺で伸縮性を損なわない弾性糸が好ましい。また、弾性糸に特殊ポリマーや粉体を添加することにより、高セット性、抗菌性、吸湿、吸水性等の機能性を付与した弾性糸も使用可能である。 The elastic yarn constituting the elastic fabric of the present invention is a polyurethane-based or polyether ester-based elastic yarn. For example, a polyurethane-based elastic yarn that is dry-spun or melt-spun can be used. It is not limited. The breaking elongation of the elastic yarn is preferably about 400% to 1000%, and is preferably an elastic yarn that is excellent in stretchability and does not impair the stretchability at around 180 ° C., which is a normal processing temperature in the presetting process during dyeing. In addition, an elastic yarn imparted with functionality such as high setability, antibacterial properties, moisture absorption, water absorption, etc. by adding a special polymer or powder to the elastic yarn can also be used.
さらに本発明の弾性織物は、弾性糸に無機物質を含有させる事が可能で、含有する無機物質の性能を加味した織物とすることが出来、例えば、酸化チタンを含有させると、織物の発熱を酸化チタンに蓄え、遠赤外線効果による保温性が付与できる。無機物質の含有法については、弾性糸の紡糸原液に無機物質を含有させて紡糸する方法が最も簡単に含有させることが可能である。本発明でいう無機物質とは、酸化チタン等のセラミックス、カーボン、カーボンブラック等の無機物及び無機化合物であり、弾性糸の紡糸の障害とならない様、微粉末状が好ましい。これら無機物質を弾性糸に１〜１０重量％含有させていることが好ましく、無機物質を含有することにより、織物の伸長発熱時、保温効果をより効果的に発揮する事が可能となる。なお、無機物質は少ないと保温効果が小さく、多すぎると紡糸時や伸長時に糸切れする事があるため、１〜１０重量％の含有が好ましく、より好ましくは２〜５重量％の含有である。 Furthermore, the elastic woven fabric of the present invention can contain an inorganic substance in the elastic yarn, and can be made into a woven fabric that takes into account the performance of the contained inorganic substance. It can be stored in titanium oxide and given heat retention by the far infrared effect. As for the method of containing an inorganic substance, the method of spinning an elastic yarn containing an inorganic substance in a spinning stock solution of elastic yarn can be most easily contained. The inorganic substance referred to in the present invention is ceramics such as titanium oxide, inorganic substances such as carbon and carbon black, and inorganic compounds, and is preferably in a fine powder form so as not to hinder spinning of elastic yarn. These inorganic substances are preferably contained in the elastic yarn in an amount of 1 to 10% by weight. By containing the inorganic substance, the heat retention effect can be more effectively exhibited when the fabric is stretched and heated. In addition, if there is little inorganic substance, the heat retention effect is small, and if it is too much, the yarn may break during spinning or stretching, so the content is preferably 1 to 10% by weight, more preferably 2 to 5% by weight. .
本発明の弾性織物を構成する非弾性糸としては、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等のポリエステル系繊維、ポリアミド系繊維、ポリプロピレン等のポリオレフィン系繊維、さらに、キュプラ、レーヨン、綿、竹繊維等のセルロース系繊維、羊毛等の獣毛繊維等、あらゆる繊維の使用が可能で、非弾性糸にセルロース等の吸湿発熱する素材を使用すれば、着用時吸湿により発熱し、運動することによっても発熱する事になり、本発明の効果をより発揮することが可能である。さらに、紡績糸の使用や起毛により発熱した熱を逃がし難くし、保温効果を高めることも可能である。 Non-elastic yarns constituting the elastic fabric of the present invention include polyester fibers such as polyethylene terephthalate and polytrimethylene terephthalate, polyamide fibers, polyolefin fibers such as polypropylene, and cupra, rayon, cotton, bamboo fibers and the like. Any fiber such as cellulosic fiber and animal fiber such as wool can be used. If a material that absorbs moisture such as cellulose is used for the non-elastic yarn, it generates heat when absorbed and also generates heat when exercised. As a result, the effects of the present invention can be further exhibited. Furthermore, it is possible to make it difficult to release the heat generated by using spun yarn and raising, and to enhance the heat retaining effect.
さらに、ポリエステル系繊維、ポリアミド系繊維およびセルロース系繊維等も、無機物質を０．３〜５重量％含有していることが好ましく、無機物質を含有することにより、弾性織物の発熱時、保温効果をより効果的に発揮する事が可能となる。なお、無機物質は、少ないと保温効果が小さく、多すぎると紡糸時や伸長時に糸切れする事があるため、０．５〜５重量％の含有が好ましく、より好ましくは０．４〜３重量％の含有である。また、これらの繊維のブライト糸、セミダル糸、フルダル糸等も任意に使用でき、繊維の断面形状も丸型、楕円型、Ｗ型、繭型、中空糸等任意な断面形状の繊維の使用が可能で、非弾性糸の繊度としては、特に限定されないが、５０〜２００ｄｔｅｘ程度であれば、例えばサポーターに加工した場合、着用時にソフトな風合いの製品となる。 Furthermore, polyester fibers, polyamide fibers, cellulose fibers and the like preferably also contain 0.3 to 5% by weight of an inorganic substance. By containing an inorganic substance, the heat-insulating effect is generated when the elastic fabric is heated. Can be demonstrated more effectively. If the inorganic substance is small, the heat retention effect is small, and if it is too large, the yarn may break during spinning or stretching. Therefore, the content is preferably 0.5 to 5% by weight, more preferably 0.4 to 3% by weight. % Content. Bright fibers, semi-dal yarns, full-dal yarns, etc. of these fibers can also be used arbitrarily, and fibers having an arbitrary cross-sectional shape such as round, elliptical, W-shaped, saddle-shaped, hollow fiber can be used. The fineness of the inelastic yarn is not particularly limited, but if it is about 50 to 200 dtex, for example, when processed into a supporter, it becomes a product with a soft texture when worn.
また、織物中の繊維の形態についても特に限定されず、原糸や仮撚等の捲縮加工糸が使用でき、さらに、長繊維、紡績糸、２種以上の繊維の撚糸、カバーリングまたはエアー混繊等により弾性糸と非弾性糸を混合した被覆弾性糸の使用も可能で、本発明の弾性織物では被覆弾性糸の使用が好ましい。弾性糸をこれらの被覆弾性糸とする場合、弾性糸と非弾性糸との長さ比率は任意に設定可能であるが、弾性糸の長さに対し非弾性糸の長さを２．５〜３．５倍程度となるよう弾性糸を伸長して被覆弾性糸として使用すれば、織物の長さに対する織物中の弾性糸の長さの比を１．７〜３．０に設定しやすくなる。なお、これら被覆弾性糸で使用する非弾性糸については、５０〜１７０ｄｔ程度の繊度の糸を被覆すれば、風合いやパワー感に優れる弾性織物が得やすい。 Further, the form of fibers in the woven fabric is not particularly limited, and crimped yarns such as raw yarns and false twists can be used. Further, long fibers, spun yarns, twisted yarns of two or more types of fibers, coverings or air It is also possible to use a covered elastic yarn in which an elastic yarn and an inelastic yarn are mixed by blending or the like, and it is preferable to use a covered elastic yarn in the elastic fabric of the present invention. When these elastic yarns are covered elastic yarns, the length ratio of the elastic yarn and the non-elastic yarn can be arbitrarily set, but the length of the non-elastic yarn is 2.5 to 2.5 with respect to the length of the elastic yarn. If the elastic yarn is stretched to be about 3.5 times and used as a coated elastic yarn, the ratio of the length of the elastic yarn in the fabric to the length of the fabric can be easily set to 1.7 to 3.0. . In addition, about the inelastic thread | yarn used with these covering elastic yarns, if the thread | yarn of the fineness of about 50-170dt is coat | covered, it will be easy to obtain the elastic fabric excellent in a texture and a power feeling.
本発明の弾性織物の組織は、タフタ、ツイル、サテン、ジャカード組織等任意で、これらの変化組織の使用も可能である。
本発明の弾性織物の染色仕上げ方法は、通常の染色仕上げ工程が使用でき、使用する繊維素材に応じた染色条件とし、使用する染色機も液流染色機、ウインス染色機、パドル染色機など任意である。
The texture of the elastic woven fabric of the present invention can be arbitrarily selected from taffeta, twill, satin, jacquard texture, and the like.
The dyeing and finishing method of the elastic fabric of the present invention can use a normal dyeing finishing process, and the dyeing conditions according to the fiber material to be used. It is.
また、吸水性や柔軟性を向上させる加工剤の使用も可能であるが、シリコン系の加工剤では糸の滑り効果が高く、伸長時の発熱効果も低いため、糸の滑り効果が少なくなるようにポリエステル系等の非シリコン系の仕上げ剤を使用するか、または仕上げ剤を使用しないで製品とすることが好ましい。 It is also possible to use processing agents that improve water absorption and flexibility, but silicon processing agents have a high thread sliding effect and a low heat generation effect when stretched, so that the thread sliding effect is reduced. It is preferable to use a non-silicone-based finishing agent such as polyester, or to make a product without using a finishing agent.
本発明の弾性織物は、タイツ、シャツ等の衣服の他、関節部を覆う、身体に密着したサポーターとして使用すればより効果が発揮でき、故障予防、故障の治癒を目的に大きな効果が発揮できる。サポーターとして使用する場合、弾性糸は２００〜４００ｄｔｅｘ程度の弾性糸を使用して織物を製造し、９．８Ｎ荷重下での経伸度および／または緯伸度を６０〜１２０％とすればより発熱し易くなる。
また、サポーターでは部分的に伸びにくい部分を形成することも可能で、この場合、弾性織物に上から伸びにくい布帛を張り付ける方法、あるいは、弾性織物と伸びにくい布帛とを接ぎ合わす方法等任意な方法により行える。
The elastic woven fabric of the present invention can be more effective when used as a supporter that covers joints in addition to clothes such as tights and shirts, and can exert a large effect for the purpose of failure prevention and failure healing. . When used as a supporter, if the elastic yarn is made of an elastic yarn of about 200 to 400 dtex and the woven fabric is manufactured and the warp elongation and / or weft elongation under a load of 9.8 N is 60 to 120%, It becomes easy to generate heat.
In addition, it is possible to form a portion that is not easily stretched by the supporter. In this case, an arbitrary method such as a method of attaching a fabric that is difficult to stretch to the elastic fabric or a method of bonding the elastic fabric and a fabric that is difficult to stretch is used. It can be done by the method.
