Description
本発明は、編地及び該編地を用いた衣服に関する The present invention relates to knitted fabrics and garments using the knitted fabrics.
従来、身体の補整や運動による故障を防止するガードルやサポーター、下肢の静脈環流を促進する弾性ストッキング等、比較的着用時の着圧が高い衣服は、弾性糸が挿入された編地を使用して衣服縫製され、また、衣服着用時の着圧効果の発揮や締め付けによる不快感を覚えないように多くのサイズ展開がなされている。特に弾性ストッキングにおいては、５種類以上のサイズ展開がされており、製造上の管理が煩雑となっている。さらに、身体のサイズが異なる複数の着用者も同サイズの衣服を着用することもあり、この場合、衣服のサイズに対して身体のサイズが大きい着用者と、衣服のサイズに対して身体のサイズが小さい着用者との間では、衣服の着圧が当然異なり、着用者によっては不快であったり、衣服着用の効果が発揮できないことがある。
これらのサイズ展開の煩雑さや、同サイズの衣服着用時の着用者間の不快感や衣服着用の効果の差異を無くすためには、編地伸長時の応力増加が小さい編地を使用して衣服とすることが最も効果的であるが、現在までにそのような編地は存在せず、衣服製造者もサイズ展開を多くして対応するしかないのが現状である。
尚、弾性糸と非弾性糸を合撚した糸条は知られているが、例えば、以下の特許文献１に記載された糸条では合撚する撚り数が小さいため、本発明におけるように、挿入する弾性糸の伸長時の応力増加を小さくすることによって縫製する編地の伸長時応力増加を小さくするという効果は期待できず、また、特許文献１には、合撚糸を編物の挿入糸として使用する技術も開示されていない。
Traditionally, garments with relatively high pressure when worn, such as girdles and supporters that prevent body repair and exercise-related injuries, and elastic stockings that promote venous circulation in the lower limbs, use knitted fabrics with elastic threads inserted. The clothes are sewn together, and many sizes are available so that the pressure effect when wearing the clothes and the discomfort caused by tightening are not felt. In particular, elastic stockings are available in five or more sizes, which complicates manufacturing management. In addition, multiple wearers of different body sizes may also wear garments of the same size, in which case the wearer who is larger than the size of the garment and the size of the body relative to the size of the garment. Of course, the pressure of the clothes is different from that of the wearer who has a small size, and some wearers may be uncomfortable or the effect of wearing the clothes may not be exhibited.
In order to eliminate the complexity of these sizes, the discomfort between wearers when wearing clothes of the same size, and the difference in the effect of wearing clothes, the clothes are made using a knitted fabric with a small increase in stress when the knitted fabric is stretched. However, there is no such knitted fabric so far, and the garment manufacturers have no choice but to increase the size development.
It should be noted that a yarn obtained by twisting an elastic yarn and an inelastic yarn is known, but for example, in the yarn described in Patent Document 1 below, the number of twists to be twisted is small, so that as in the present invention, By reducing the increase in stress during elongation of the elastic yarn to be inserted, the effect of reducing the increase in stress during elongation of the knitted fabric to be sewn cannot be expected. Further, in Patent Document 1, a twisted yarn is used as an insertion yarn for knitting. The technology used is also not disclosed.
前記した従来技術に鑑み、本発明が解決しようとする課題は、着用者の身体サイズが異なっても着圧が同じようになり、サイズ適応性に優れ、かつ、品位に優れる衣服とすることができる編地及び該編地を用いた衣服を提供することである。 In view of the above-mentioned prior art, the problem to be solved by the present invention is to obtain clothes having the same wearing pressure even if the body size of the wearer is different, excellent in size adaptability, and excellent in dignity. It is to provide a knitted fabric that can be made and clothes using the knitted fabric.
本発明者らは、上記課題を解決すべく鋭意検討し実験を重ねた結果、サイズ適応性に優れる衣服は、縫製する編地の伸長時応力増加を小さくすればよく、そのために、挿入する弾性糸の伸長時の応力増加を小さくすれば可能であり、それには、挿入する弾性糸を、所定の撚り数で撚糸すればよいことを予想外に見出し、本発明を完成するに至ったものである。 As a result of diligent studies and experiments to solve the above problems, the present inventors need to reduce the increase in stress during elongation of the knitted fabric to be sewn for the garment having excellent size adaptability. This is possible by reducing the increase in stress during elongation of the yarn, and it was unexpectedly found that the elastic yarn to be inserted should be twisted with a predetermined number of twists, which led to the completion of the present invention. is there.

以下、本発明の実施形態を詳細に説明する。
本実施形態の編地は、挿入組織を有する編地であって、撚り数２００〜１０００Ｔ／ｍで撚糸された弾性糸を含む糸条が該挿入組織に挿入されていることを特徴とする。
Hereinafter, embodiments of the present invention will be described in detail.
The knitted fabric of the present embodiment is a knitted fabric having an insertion structure, and is characterized in that a thread containing an elastic yarn twisted at a twist number of 200 to 1000 T / m is inserted into the insertion structure.
本実施形態の編地は、緯編地であっても経編地であってもよい。緯編地であれば、釜径４〜５インチ程度の小口径のシングル丸編機（パンスト編機とも称される）を含む丸編機により、経編地であれば、ラッセル編機等の経編機により製造可能である。編機のゲージは特に限定されず、インナーやストッキング、サポーター等のアイテムにより最適なゲージと糸使いが選定できる。 The knitted fabric of the present embodiment may be a weft knitted fabric or a warp knitted fabric. For weft knitted fabrics, a circular knitting machine including a single circular knitting machine (also called a pantyhose knitting machine) with a small diameter of about 4 to 5 inches, and for warp knitted fabrics, a Russell knitting machine, etc. It can be manufactured by a warp knitting machine. The gauge of the knitting machine is not particularly limited, and the optimum gauge and thread usage can be selected according to items such as inners, stockings, and supporters.
本実施形態の編地は、挿入組織を有する編地であって、撚り数２００〜１０００Ｔ／ｍで撚糸された弾性糸を含む糸条が該挿入組織に挿入されている。撚り数２００〜１０００Ｔ／ｍで撚糸された弾性糸を含む糸条を挿入することにより、編地伸長時の応力増加が撚糸前の弾性糸に比べて低く抑えられる。この特性を利用することにより、これまでの製品には見られない新しい効果を有する製品、すなわち、着用者の身体サイズが異なっても着圧が同じようになり、サイズ適応性に優れ、かつ、品位に優れる衣服とすることができる。 The knitted fabric of the present embodiment is a knitted fabric having an insertion structure, and a yarn containing an elastic yarn twisted at a twist number of 200 to 1000 T / m is inserted into the insertion structure. By inserting a yarn containing an elastic yarn twisted at a twist number of 200 to 1000 T / m, the increase in stress during elongation of the knitted fabric can be suppressed to be lower than that of the elastic yarn before twisting. By utilizing this characteristic, a product with a new effect not found in conventional products, that is, the wearing pressure becomes the same even if the wearer's body size is different, and it is excellent in size adaptability and The clothes can be of excellent quality.
本実施形態の編地における「撚糸された弾性糸を含む糸条」とは、弾性糸のみが撚糸された糸条、弾性糸と非弾性糸との合撚糸からなる糸条、撚糸された弾性糸を芯糸とし、該芯糸に非弾性糸が巻き付けられた被覆弾性糸からなる糸条のいずれでもよく、いずれであっても所望の効果が発揮される。弾性糸を撚糸する方法は既存の撚糸機が使用できるが、撚糸時に弾性糸が均一に伸長されるよう積極送りの付いた撚糸機の方が、弾性糸が消極送りで撚糸される場合よりも、撚り斑が発生しにくく、また編地の緯段や経て筋が発生しにくいため好ましい。 The "thread including the twisted elastic yarn" in the knitted fabric of the present embodiment means a yarn in which only the elastic yarn is twisted, a yarn composed of a combined twisted yarn of an elastic yarn and an inelastic yarn, and a twisted elastic yarn. Any of the yarns made of a coated elastic yarn in which a yarn is used as a core yarn and an inelastic yarn is wound around the core yarn, and any of them exhibits a desired effect. An existing twisting machine can be used for twisting the elastic yarn, but a twisting machine with a positive feed so that the elastic yarn is uniformly stretched at the time of twisting is better than a twisting machine in which the elastic yarn is twisted by a negative feed. , Twisting spots are less likely to occur, and streaks are less likely to occur in the weft and passage of the knitted fabric, which is preferable.
本実施形態の編地における弾性糸とは、最大伸度１００％以上の繊維を指す。弾性糸は、ポリウレタン系又はポリエーテルエステル系の弾性糸であることができ、例えば、ポリウレタン系弾性糸としては、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、また、伸縮性に優れ、染色加工時のプレセット工程の通常処理温度１８０℃近辺で伸縮性を損なわないことが好ましい。また、弾性糸としては、特殊ポリマーや粉体添加により、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 in the knitted fabric of the present embodiment refers to a fiber having a maximum elongation of 100% or more. The elastic yarn can be a polyurethane-based or a polyether ester-based elastic yarn. For example, as the polyurethane-based elastic yarn, a dry-spun or melt-spun yarn can be used, and the polymer and the spinning method are not particularly limited. The elongation at break of the elastic yarn is preferably about 400% to 1000%, and it is preferable that the elastic yarn has excellent elasticity and does not impair the elasticity at a normal treatment temperature of about 180 ° C. in the presetting process during dyeing. Further, as the elastic yarn, an elastic yarn having high settability, antibacterial property, moisture absorption, water absorption and the like can be used by adding a special polymer or powder.
本実施形態の編地に挿入される「撚糸された弾性糸を含む糸条」の弾性糸の撚り数については、弾性糸の繊度にかかわらず、２００〜１０００Ｔ／ｍであれば、無撚糸よりも伸長時の応力は大きく低下し、サイズ適応性に優れる衣服とすることができる。撚り数が２００Ｔ／ｍ未満であると、伸長時の応力増加が大きく所望の効果を発揮できず、他方、撚り数が１０００Ｔ／ｍを超えると、編成時の解除でスナールが発生して品位が悪化し、さらに、編成困難となり易く、さらに、コストが高くなりすぎる。「撚糸された弾性糸を含む糸条」の弾性糸の撚り数は、好ましくは３００〜８００Ｔ／ｍである。 Regarding the number of twists of the elastic yarn of the "thread including the twisted elastic yarn" inserted into the knitted fabric of the present embodiment, if it is 200 to 1000 T / m regardless of the fineness of the elastic yarn, it is more than the untwisted yarn. However, the stress during elongation is greatly reduced, and the garment can be made with excellent size adaptability. If the number of twists is less than 200 T / m, the stress increase during elongation is large and the desired effect cannot be exhibited. On the other hand, if the number of twists exceeds 1000 T / m, snails are generated due to release during knitting and the quality is deteriorated. It gets worse, it tends to be difficult to organize, and the cost is too high. The number of twists of the elastic yarn of the "thread including the twisted elastic yarn" is preferably 300 to 800 T / m.
本実施形態の編地に含まれる弾性糸の繊度については、３０〜５００ｄｔｅｘ（デシテックス：以下同じ記号を使用する）が好ましい。３０ｄｔｅｘ以上であれば着圧が高い衣料として用いることができ、他方、５００ｄｔｅｘ以下であれば伸長時の応力が高すぎず着用しやすい衣料となるため好ましい。弾性糸の繊度は、より好ましくは４０〜４００ｄｔｅｘである。尚、弾性糸の繊度の測定においては、編地中から「撚糸された弾性糸を含む糸条」を抜き出し、合撚糸の場合は弾性糸と非弾性糸とを解撚し、解撚後の弾性糸に０．１ｇの荷重をかけて長さと重量から繊度を求める。 The fineness of the elastic yarn contained in the knitted fabric of the present embodiment is preferably 30 to 500 dtex (decitex: the same symbol is used hereinafter). If it is 30 dtex or more, it can be used as a garment with a high wearing pressure, while if it is 500 dtex or less, the stress at the time of extension is not too high and the garment is easy to wear, which is preferable. The fineness of the elastic yarn is more preferably 40 to 400 dtex. In measuring the fineness of elastic yarns, "threads containing twisted elastic yarns" are extracted from the knitted fabric, and in the case of combined twisted yarns, elastic yarns and inelastic yarns are untwisted, and after untwisting. A load of 0.1 g is applied to the elastic yarn, and the fineness is obtained from the length and weight.
本実施形態の編地に挿入される糸条は、「弾性糸と非弾性糸との合撚糸」であってもよい。具体的には、弾性糸を撚糸する際、同時に非弾性糸を引き揃えて合撚する方法が最も簡単である。また、本実施形態の編地に挿入される糸条は、「撚糸された弾性糸を芯糸とし、該芯糸に非弾性糸が巻き付けられた被覆弾性糸」であってもよい。いずれも場合も、弾性糸と非弾性糸とのドラフト率（糸長比）、すなわち、編成時の弾性糸長に対する非弾性糸長の比は任意であるが、２．５〜４．５が好ましく、より好ましくは２．８〜４．０が好ましい。ドラフト率が２．５以上であれば十分に高伸度の編地が得られ、ドラフト率が４．５以下またであれば編成上問題なく、また、２．５〜４．５の範囲にあることで好適な着圧を有する衣服とすることができる。 The yarn inserted into the knitted fabric of the present embodiment may be a "combined twisted yarn of elastic yarn and inelastic yarn". Specifically, when twisting elastic yarns, the simplest method is to pull the inelastic yarns together and twist them together. Further, the yarn inserted into the knitted fabric of the present embodiment may be "a coated elastic yarn in which a twisted elastic yarn is used as a core yarn and an inelastic yarn is wound around the core yarn". In each case, the draft ratio (thread length ratio) of the elastic thread and the inelastic thread, that is, the ratio of the inelastic thread length to the elastic thread length at the time of knitting is arbitrary, but 2.5 to 4.5. It is preferable, more preferably 2.8 to 4.0. If the draft rate is 2.5 or more, a knitted fabric with sufficiently high elongation can be obtained, and if the draft rate is 4.5 or less, there is no problem in knitting, and the range is 2.5 to 4.5. It is possible to obtain clothes having a suitable wearing pressure.
本実施形態の編地における非弾性糸とは、最大伸度が１００％未満の繊維を指す。非弾性糸としては長繊維、短繊維ともに使用可能であり、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、並びにポリプロピレン等の合成繊維、アセテート等の半合成繊維、綿、キュプラ、レーヨン等のセルロース系繊維、羊毛等の獣毛繊維等各種繊維の使用が可能である。また、これらのブライト糸、セミダル糸、フルダル糸等を任意に使用でき、繊維の断面形状についても、丸型、楕円型、Ｗ型、繭型、中空糸等任意の断面形状の繊維が使用可能であり、繊維の形態についても特に限定されず、原糸、仮撚等の捲縮加工糸が使用でき、また、酸化チタン等の無機物質や、吸湿に優れる添加剤を０．３〜５．０重量％含有させることも可能で、これらを含有することにより、放熱性や吸湿性、吸汗性等にも優れる編地が製造できる。さらに、非弾性糸の太さは１０〜１７０ｄｔｅｘ、好ましくは１５〜１２０ｄｔｅｘの非弾性糸の使用が好適である。 The inelastic yarn in the knitted fabric of the present embodiment refers to a fiber having a maximum elongation of less than 100%. Both long fibers and short fibers can be used as the inelastic yarn, and polyester fibers such as polyethylene terephthalate and polytrimethylene terephthalate, polyamide fibers, synthetic fibers such as polypropylene, semi-synthetic fibers such as acetate, cotton and cupra It is possible to use various fibers such as cellulose fibers such as rayon and animal hair fibers such as wool. In addition, these bright yarns, semi-dull yarns, full-dull yarns, etc. can be used arbitrarily, and fibers having any cross-sectional shape such as round, elliptical, W-shaped, cocoon-shaped, hollow yarns, etc. can be used. The form of the fiber is not particularly limited, and crimped yarn such as raw yarn and false twist can be used, and inorganic substances such as titanium oxide and additives having excellent moisture absorption are added at 0.3 to 5. It is also possible to contain 0% by weight, and by containing these, a knitted fabric having excellent heat dissipation, moisture absorption, sweat absorption and the like can be produced. Further, it is preferable to use an inelastic yarn having a thickness of 10 to 170 dtex, preferably 15 to 120 dtex.
本実施形態の編地は、「撚糸された弾性糸を含む糸条」が挿入された挿入組織を含有している。該糸条の挿入のされ方については特に限定されないが、緯編地の場合、全コース、又は１〜４コースおきに（１〜４コースを空けて）、該糸条が１本挿入されていることが、サイズ適応性の観点から好ましい。尚、例えば、３コースおきに１本挿入とは、撚糸した弾性糸の糸条を１コース挿入後、次の３コースは挿入しないということを意味する。また、経編地の場合、オールイン、又は１イン１〜４アウトで挿入することが、サイズ適応性の観点から好ましい。 The knitted fabric of the present embodiment contains an insertion structure into which "threads including twisted elastic yarns" are inserted. The method of inserting the thread is not particularly limited, but in the case of a weft knitted fabric, one thread is inserted at all courses or every 1 to 4 courses (with 1 to 4 courses open). It is preferable from the viewpoint of size adaptability. For example, inserting one every three courses means that after inserting one course of the twisted elastic yarn, the next three courses are not inserted. Further, in the case of a warp knitted fabric, it is preferable to insert it all-in or 1-in 1 to 4 out from the viewpoint of size adaptability.
緯編地、経編地ともに、挿入量が増すほどハイパワーの編地となる。また、緯編地であるか経編地であるかは衣服の目的に応じて選定することができる。
撚糸した弾性糸を含む糸条を挿入する編地の地組織については特に限定されないが、具体例として、緯編地では、シングル編地の天竺、鹿の子等、ダブル編地ではスムース、ポンチローマ等任意である。また、経編では、クインズコードやハーフ組織に挿入組織を組み入れる方法や、ラッセル編機では既存のルーピング組織と挿入組織とを組み合わせた、例えば、６コースサテン、６コースチュール、ツインパワーといった組織の使用が可能である。また、撚糸した弾性糸を含む糸条以外の弾性糸を使用することも可能であり、例えば、弾性糸をプレーティングで編成することも可能である。
Both the weft knitted fabric and the warp knitted fabric become higher power knitted fabric as the insertion amount increases. In addition, whether it is a weft knitted fabric or a warp knitted fabric can be selected according to the purpose of the garment.
The texture of the knitted fabric into which the yarn containing the twisted elastic yarn is inserted is not particularly limited, but as a specific example, for the weft knitted fabric, a single knitted fabric such as Tenjiku or Kanoko, and for a double knitted fabric, smooth, punch roma, etc. It is optional. In the warp knitting, the method of incorporating the insertion tissue into the quinz cord or half tissue, and in the Russell knitting machine, the existing looping structure and the insertion structure are combined, for example, 6-course satin, 6-course tulle, and twin power. It can be used. It is also possible to use elastic yarns other than yarns including twisted elastic yarns, and for example, elastic yarns can be knitted by plating.
挿入組織については、緯編地においては、例えば、天竺組織中に緯方向にタックとウェルト（ミスとも称される）を交互に繰り返す等の、タックとウェルトを組み合わせた組織とすることができる。また、弾性撚糸の繊度が１００ｄｔｅｘ以下の場合、緯方向にニットとタックを交互に繰り返す等の、ニットとタックとの組み合わせ組織も可能であり、さらには、ニットとタック、ウェルトとを組み合わせた組織を使用できるが、タックとウェルトのみの方が本発明の効果が高くなるため、好ましい。 As for the insertion structure, in the weft knitted fabric, for example, the structure in which the tack and the welt are combined can be formed by alternately repeating the tack and the welt (also referred to as a mistake) in the weft direction in the plain structure. Further, when the fineness of the elastic twisted yarn is 100 dtex or less, a knit and tack combination structure such as repeating knit and tack alternately in the weft direction is possible, and further, a knit and tack and welt combination structure is possible. However, only tack and welt are preferable because the effect of the present invention is higher.
また、経編地においては、例えばラッセル編機を使用した場合、００／１１／００／２２／００／１１／／、又は、００／１１／／等の挿入組織が使用できる。また、弾性撚糸の繊度が１００ｄｔｅｘ以下の場合、１０／１１／／等のニットと挿入の組み合わせも可能であるが、挿入組織のみの方が、所望の効果が高くなるため、好ましい。 Further, in the warp knitted fabric, for example, when a Russell knitting machine is used, an insertion structure such as 00/11/00/22/00/11 // or 00/11 // can be used. Further, when the fineness of the elastic twisted yarn is 100 dtex or less, a combination of knitting and insertion such as 10/11 // is possible, but only the inserted structure is preferable because the desired effect is higher.
さらに、弾性糸に無機物質を含有することが可能で、含有する無機物質の性能を加味した編地とすることができ、例えば、酸化チタンを含有させると、熱伝導性に優れ、放熱性の良い編地とすることができる。無機物質の含有法としては、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である。無機物質とは、酸化チタン等のセラミックスの無機物単体及び／又は無機化合物をいい、弾性糸の紡糸の障害とならない様、微粉末状が好ましい。これら無機物質は、弾性糸に１〜１０重量％含有されていることが好ましく、より好ましくは２〜５重量％である。無機物質の含有量が低いと、無機物質の持つ効果が発揮されず、高すぎると、紡糸時や伸長時に糸切れすることがある。 Further, the elastic yarn can contain an inorganic substance, and the knitted fabric can be made in consideration of the performance of the contained inorganic substance. For example, when titanium oxide is contained, the elastic yarn has excellent thermal conductivity and heat dissipation. It can be a good knitted fabric. The simplest method for containing an inorganic substance is to add an inorganic substance to the spinning stock solution of elastic yarn and spin the yarn. The inorganic substance refers to a simple substance and / or an inorganic compound of ceramics such as titanium oxide, and is preferably in the form of a fine powder so as not to interfere with the spinning of elastic yarn. These inorganic substances are preferably contained in the elastic yarn in an amount of 1 to 10% by weight, more preferably 2 to 5% by weight. If the content of the inorganic substance is low, the effect of the inorganic substance is not exhibited, and if it is too high, the yarn may break during spinning or stretching.
本実施形態の編地の染色仕上げ方法としては、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、ウインス染色機およびパドル染色機など任意で、吸水性や柔軟性を向上させる加工剤の使用も行える。 As a dyeing finishing method for the knitted fabric of the present embodiment, a normal dyeing finishing step can be used, the dyeing conditions are set according to the fiber material used, and the dyeing machines used are a liquid flow dyeing machine, a wins dyeing machine and a paddle dyeing machine. You can also use a processing agent that improves water absorption and flexibility.
本実施形態の編地を衣服に用いる場合、緯編地、経編地ともに、挿入された撚糸した弾性糸を含む糸条が、衣服として伸長されやすい方向と同方向に配向するように編地が含まれることが、所望の効果がより高くなるため好ましい。 When the knitted fabric of the present embodiment is used for garment, both the weft knitted fabric and the warp knitted fabric are knitted so that the yarns including the inserted twisted elastic yarns are oriented in the same direction as the garment is easily stretched. Is preferable because the desired effect is higher.
本実施形態の編地を用いた衣服は、身体に密着して着用される衣服であることが好ましい。具体的には、下記式：
ゆとり率％＝｛（衣服のサイズ）−（身体のサイズ）｝／（身体のサイズ）×１００
｛式中、衣服のサイズは、身体と衣服との同位置での衣服の周径であり、身体のサイズは、身体と衣服との同位置での身体の周径である。｝
で求められる、ゆとり率が０％以下の衣服の場合、所望効果が最も効果的に奏される。
The garment using the knitted fabric of the present embodiment is preferably a garment worn in close contact with the body. Specifically, the following formula:
Clearance rate% = {(clothing size)-(body size)} / (body size) x 100
{In the formula, the size of the garment is the circumference of the garment at the same position between the body and the garment, and the size of the body is the circumference of the body at the same position between the body and the garment. }
In the case of clothes having a clearance rate of 0% or less, which is required in the above, the desired effect is most effectively exhibited.
本実施形態の衣服では、衣服全体が身体に密着する衣服の他、部分的に身体に密着する衣服でもサイズ適応性に優れる効果が発揮される。 In the clothes of the present embodiment, in addition to clothes in which the entire clothes are in close contact with the body, clothes in which the clothes are partially in close contact with the body also exhibit an effect of excellent size adaptability.

また、脚型が大きくなることによる着圧増加率を下記式：
着圧増加率（％）＝｛（９号脚型の着圧）―(６号脚型の着圧）｝／(６号脚型の着圧)×１００
により求める。
着圧増加率が低いほど、サイズ適応性に優れ、本実施例では２０％以下着圧増加率を合格とし、１０％以下を特にサイズ適応性に優れるものとした。
