In that case, in the said ventilation | gas_flowing part, it is preferable that the length of the width direction is in the range of 5-50 cm. Moreover, it is preferable that two ventilation parts are formed in the mutually different position in the length direction, and the space | interval of these ventilation parts is 15 cm or more. Moreover, it is preferable that air permeability is smaller than the said ventilation | gas_flowing part in the site | parts other than the said ventilation | gas_flowing part, and exists in the range of 20-350 cc / cm < 2 > / sec. Moreover, it is preferable that the maximum value of the clearance amount is 1.1 times or more in the width direction or the length direction in a portion having a space.

本考案によれば、換気を促進し衣服内部の温度や湿度を効果的に低減可能な衣服が得られる。 According to the present invention, a garment capable of promoting ventilation and effectively reducing the temperature and humidity inside the garment can be obtained.
以下、本考案の実施の形態について詳細に説明する。
まず、本考案の衣服は、２箇所以上の通気部を備えている。ここで、通気部の箇所数は２箇所以上（より好ましくは２箇所）であることが肝要である。該箇所数が１箇所以下の場合、衣服内部で十分な換気が行われないおそれがあり好ましくない。特に、通気部が、着丈方向に互いに異なる位置に２箇所形成されており、かつこれら通気部同士の間隔が１５ｃｍ以上（より好ましくは２０〜４０ｃｍ）であると、衣服を着用した際に下方に位置する通気部が吸気口となり、一方上方に位置する通気部が排気口となって煙突効果により衣服内部で十分な換気が行われ好ましい。該間隔が１５ｃｍよりも小さい場合、煙突効果が低下し、十分な放熱が行われないだけでなく、対流スペースも減少することから、下記のふいご作用による放熱も低下するおそれがある。なお、通気部同士の間隔は、一方通気部の中心点から他方通気部の中心点までの直線距離を測定するものとする。
Hereinafter, embodiments of the present invention will be described in detail.
First, the clothes of the present invention have two or more ventilation portions. Here, it is important that the number of ventilation portions is two or more (more preferably two). When the number of places is 1 or less, there is a possibility that sufficient ventilation is not performed inside the clothes, which is not preferable. In particular, when the ventilation portion is formed at two positions different from each other in the length direction, and the interval between the ventilation portions is 15 cm or more (more preferably 20 to 40 cm), when the garment is worn, It is preferable that the ventilation portion positioned as an intake port and the ventilation portion positioned above as an exhaust port provide sufficient ventilation within the garment due to the chimney effect. If the distance is smaller than 15 cm, the chimney effect is reduced, and not only sufficient heat dissipation is not performed, but also the convection space is reduced. In addition, the space | interval of ventilation parts shall measure the linear distance from the center point of one ventilation part to the center point of the other ventilation part.
前記通気部の大きさとしては、衣服内部の換気を促進する上で、着巾方向の長さが５〜５０ｃｍの範囲内であることが好ましく、着丈方向の長さが０．５ｃｍ〜２５ｃｍ（より好ましくは１〜１５ｃｍ）であることが好ましい。着巾方向の長さが５ｃｍ未満の場合または着丈方向の長さが１ｃｍ未満の場合、衣服内部の換気が十分行われないおそれがある。逆に、着巾方向の長さが５０ｃｍよりも大きい場合または着丈方向の長さが２５ｃｍよりも大きい場合、着用者が静止した状態でも十分衣服内部の換気が行われるため、着用者が動いた際の清涼感を体感することが難しくなるおそれがある。
ここで、着丈方向および着巾方向の長さとは、衣服を平面上に拡げて、無荷重で放置した際に計測できる長さを意味する。
As the size of the ventilation portion, in order to promote ventilation inside the clothes, the length in the width direction is preferably in the range of 5 to 50 cm, and the length in the length direction is 0.5 to 25 cm ( More preferably, it is 1-15 cm). When the length in the width direction is less than 5 cm or the length in the length direction is less than 1 cm, there is a possibility that ventilation inside the garment is not sufficiently performed. On the contrary, when the length in the width direction is larger than 50 cm or the length in the length direction is larger than 25 cm, the wearer moved because ventilation inside the clothes is sufficiently performed even when the wearer is stationary. There is a risk that it will be difficult to experience the refreshing feeling.
Here, the length in the length direction and the width direction means a length that can be measured when the clothes are spread on a flat surface and left unloaded.
前記通気部において、通気度が５０ｃｃ／ｃｍ２／ｓｅｃよりも大きいことが肝要である。より好ましくは２６０〜５００ｃｃ／ｃｍ２／ｓｅｃである。該通気度が５０ｃｃ／ｃｍ２／ｓｅｃ以下の場合、衣服内部で十分な換気が行われないおそれがあり好ましくない。一方、前記通気部以外の部位においては、通気度が前記通気部より小さくかつ２０〜３５０ｃｃ／ｃｍ２／ｓｅｃの範囲内であることが好ましい。
前記通気部は開口部（貫通孔）であってもよいし、通気度が５０ｃｃ／ｃｍ２／ｓｅｃよりも大きい生地（通気部用生地）で構成されていてもよい。
また、前記通気部の形状としては特に限定されず、長方形、楕円、三角、ひし形、円、台形、または曲線からなるこれらの形状などが例示される。
In the ventilation part, it is important that the air permeability is larger than 50 cc / cm 2 / sec. More preferably, it is 260-500 cc / cm < 2 > / sec. When the air permeability is 50 cc / cm 2 / sec or less, there is a possibility that sufficient ventilation is not performed inside the clothes, which is not preferable. On the other hand, in a portion other than the ventilation portion, it is preferable that the air permeability is smaller than that of the ventilation portion and is in a range of 20 to 350 cc / cm 2 / sec.
The ventilation portion may be an opening (through hole) or may be made of a fabric (ventilation fabric for ventilation) having an air permeability greater than 50 cc / cm 2 / sec.
The shape of the vent is not particularly limited, and examples thereof include a rectangle, an ellipse, a triangle, a rhombus, a circle, a trapezoid, or a curve.
本考案の衣服において、２箇所以上の通気部から選択されるいずれか２箇所の通気部の間に位置する部位がゆとりを有することが肝要である。２箇所の通気部の間に該生地Ａが配されることにより、着用者が動いた際に該生地Ａが振動し、ふいご作用により、一方の通気部から他方の通気部へと肌表面の対流（換気）が促進され、その結果、衣服内部の温度や湿度を効果的に低減することが可能となる。 In the garment of the present invention, it is important that a portion located between any two ventilation portions selected from two or more ventilation portions has a clearance. By arranging the fabric A between the two ventilation portions, the fabric A vibrates when the wearer moves, and the skin surface from one ventilation portion to the other ventilation portion due to a bellows action. Convection (ventilation) is promoted, and as a result, the temperature and humidity inside the clothes can be effectively reduced.
ここで、「ゆとり」とは、「服飾事典」（１９７１年５月２０日発行、同文書院発行）に記載されているように「運動量のためにとっておくゆるみ」のことであり、タックやギャザーなどが例示される。例えば、パターン設計や、衣服に開口部を形成した後に該開口部に生地を縫製などにより取り付ける際、生地の着丈方向もしくは着幅方向、またはその両方が開口部の長さよりも大とすることによりゆとりを設けることができる。 Here, “clearance” means “relaxation for momentum” as described in “Apparel Encyclopedia” (issued on May 20, 1971, published by the same documentary institution), and tack and gather Etc. are exemplified. For example, when attaching a fabric to the opening after pattern design or forming an opening in clothing, the length direction or width direction of the fabric, or both, by making the length greater than the length of the opening A space can be provided.
その際、着巾方向または着丈方向において、ゆとり量（ゆとりを有する部位の拡布寸法／ゆとりを有する部位の取付寸法）の最大値が１．１倍以上（より好ましくは１．２〜１．５倍）であると、着用者が動くことによりゆとりを有する部位が振動しふいご作用により肌表面の対流（換気）が促進され、その結果、衣服内部の温度や湿度を効果的に低減することが可能となり好ましい。なお、ゆとりが無い場合、ゆとり量（ゆとりを有する部位の拡布寸法／ゆとりを有する部位の取付寸法）は１倍となる。 At that time, in the width direction or the length direction, the maximum value of the clearance amount (expansion dimension of a part having a clearance / mounting dimension of a part having a clearance) is 1.1 times or more (more preferably 1.2 to 1.5). If the wearer moves, the part having a space vibrates and the convection (ventilation) of the skin surface is promoted by the action of the bellows. As a result, the temperature and humidity inside the clothes are effectively reduced. Is possible and preferable. In addition, when there is no space, the amount of space (expansion dimension of a part having a space / mounting dimension of a part having a space) becomes 1 time.
また、ゆとりを有する部位を構成する生地Ａにおいて、目付けが２５０ｇ／ｍ２以下（より好ましく１５０ｇ／ｍ２以下、特に好ましくは５０〜１２０ｇ／ｍ２）の生地で構成されていると、該生地が振動しやすくなりふいご作用による換気が促進され好ましい。該目付けが２５０ｇ／ｍ２よりも大きいと、着用者が動いた際にゆとりを有する部位（生地Ａ）の追従性が悪くなり、ふいご作用による肌表面の対流（換気）が低下するおそれがある。 Further, in the fabric A constituting the part having a space, when the basis weight is made of a fabric having a basis weight of 250 g / m 2 or less (more preferably 150 g / m 2 or less, particularly preferably 50 to 120 g / m 2 ), the fabric This is preferable because it is easy to vibrate and ventilation by the action of bellows is accelerated. When the basis weight is larger than 250 g / m 2, the followability of the portion (fabric A) having a space when the wearer moves is deteriorated, and convection (ventilation) on the skin surface due to the action of the belly may be lowered. is there.
また、前記生地Ａにおいて、ＪＩＳ Ｌ１０１８ ４５度カンチレバー法で測定した剛軟性が経緯平均値で１０ｍｍ以上（より好ましくは１５ｍｍ以上、特に好ましくは２０〜４０ｍｍ）であると、ふいご作用による肌表面の対流（換気）が発生しやすく好ましい。剛軟性が経緯平均値で１０ｍｍ未満の場合、生地Ａが柔らかすぎることにより対流スペース内の空気を押し出すことができないおそれがある。 Further, in the fabric A, when the bending resistance measured by the JIS L1018 45 degree cantilever method is 10 mm or more (more preferably 15 mm or more, particularly preferably 20 to 40 mm) in terms of the background average value, It is preferable because convection (ventilation) is easily generated. When the bending resistance is less than 10 mm in terms of the mean value, there is a possibility that the air in the convection space cannot be pushed out because the fabric A is too soft.
本考案の衣服において、前記通気部またはゆとりを有する部位に隣接して、ゆとりを有する前記生地Ａの１．１倍以上（より好ましくは１．５〜５．０倍）の目付けを有し、かつ４ｃｍ２以上（より好ましくは４〜１００ｃｍ２）の面積を有する生地Ｂが配されていると、着用者が動く際のかかる生地Ｂがウエイトの役目を果たし、前記生地Ａの振動を促進し、衣服内部の温度や湿度を効果的に低減することが可能となり好ましい。 In the garment of the present invention, adjacent to the portion having the ventilation portion or the space, the fabric A having a space has a basis weight of 1.1 times or more (more preferably 1.5 to 5.0 times), and when 4 cm 2 or more (more preferably 4~100cm 2) are arranged the fabric B having an area of, and acts as a weight such fabric B when moving the wearer, to promote oscillation of the workpiece a It is preferable because the temperature and humidity inside the clothes can be effectively reduced.

次いで、前記吸気口と排気口との間に開口部を形成した後、図２に模式的に示すように該開口部に前記生地Ａが生地巾にゆとりを有するよう縫製により取り付けた。その際、前記吸気口と排気口との中間点で着巾方向のゆとり量が最大（１．２５倍）となるようパターン設計にて縫製した。
次いで、図２に模式的に示すように、前記生地Ａに隣接するように目付２００ｇ／ｍ２のポリエチレンテレフタレートマルチフィラメント総繊度１５７ｄｔｅｘ／７２フィラメント１００％からなる編地（生地Ｂ）を５ｃｍ×５ｃｍ（面積２５ｃｍ２）のサイズで縫い付けて衣服を得た。
該衣服をマネキンに着用させ、ズボンはポリエステル繊維１００重量％市販ズボンを着用させた。結果、静止時の背部放熱量は８５．４Ｗ／ｍ２、歩行時の背部放熱量は１０１．０Ｗ／ｍ２で、対流放熱効果は１５．６Ｗ／ｍ２と優れた放熱性を有していた。
Next, an opening was formed between the air inlet and the air outlet, and then the cloth A was attached to the opening by sewing so as to have a space in the cloth width as schematically shown in FIG. At that time, sewing was performed with a pattern design so that the clearance in the width direction became the maximum (1.25 times) at the midpoint between the intake port and the exhaust port.
Next, as schematically shown in FIG. 2, a knitted fabric (fabric B) composed of 100% polyethylene terephthalate multifilament fineness of 157 dtex / 72 filaments having a basis weight of 200 g / m 2 so as to be adjacent to the fabric A is 5 cm × 5 cm. Clothes were obtained by sewing with a size of (area 25 cm 2 ).
The garment was worn on a mannequin, and the pants were 100% polyester fiber commercial trousers. As a result, the amount of heat released from the back at rest was 85.4 W / m 2 , the amount of heat released from the back during walking was 101.0 W / m 2 , and the convective heat release effect was 15.6 W / m 2 , which has excellent heat dissipation It was.
［実施例２］
実施例１において、生地Ｂを取りつけないこと以外は実施例１と同様にした。結果、静止時の背部放熱量は８５．２Ｗ／ｍ２、歩行時の背部放熱量は９９．０Ｗ／ｍ２で、対流放熱効果は１３．８Ｗ／ｍ２と、実施例１で得られた衣服より少し劣るものの優れた放熱性を有していた。
[Example 2]
In Example 1, it carried out similarly to Example 1 except not attaching the cloth | dough B. FIG. As a result, the back heat radiation amount at rest was 85.2 W / m 2 , the back heat radiation amount at walking was 99.0 W / m 2 , and the convective heat radiation effect was 13.8 W / m 2 , which was obtained in Example 1. Although it was slightly inferior to clothes, it had excellent heat dissipation.
［比較例１］
実施例１で使用した市販の半袖丸首シャツ（通気部や生地Ａが配されていないそのままのシャツ）をマネキンに着用させ、評価を実施した。結果、静止時の背部放熱量は８０．６Ｗ／ｍ２、歩行時の背部放熱量は８７．２Ｗ／ｍ２で、対流放熱効果は６．６Ｗ／ｍ２と低い放熱性を示した。
[Comparative Example 1]
Evaluation was carried out by causing the mannequin to wear the commercially available short-sleeved round-necked shirt used in Example 1 (the shirt without the ventilation part and the fabric A arranged). Result, the back heat radiation amount of the at rest 80.6W / m 2, the back heat radiation amount during walking is 87.2W / m 2, convection heat dissipation effect showed low heat dissipation and 6.6 W / m 2.
［比較例２］
実施例２で使用したウェアにおいて、吸気口と排気口との間に配された生地Ａにゆとりを設けない（すなわちゆとり量１倍）こと以外は実施例２と同様にして衣服を得た。結果、静止時の背部放熱量は８１．２Ｗ／ｍ２、歩行時の背部放熱量は８８．２Ｗ／ｍ２で、対流放熱効果は７．０Ｗ／ｍ２と低い放熱性を示した。
[Comparative Example 2]
In the wear used in Example 2, clothes were obtained in the same manner as in Example 2 except that no space was provided in the fabric A arranged between the intake port and the exhaust port (that is, the amount of space was 1 time). As a result, the back heat radiation amount at rest was 81.2 W / m 2 , the back heat radiation amount during walking was 88.2 W / m 2 , and the convective heat radiation effect was 7.0 W / m 2 , indicating low heat dissipation.
