The cooling material is structured as follows: the compression hardness of the ventilation flow path part 2 is 1-10 kg/Φ200; and parts other than an air-sending surface (sweat-absorptive material surface) are surrounded with a covering material 3 having no air permeability. A cooling garment is provided by using the cooling material.

Description

本発明は、酷暑下において体内からの汗を吸収、蒸発させることで、効率良く気化熱を奪うことによって、人体の体温上昇を抑制することが可能な冷却材料に関する。詳細には、密閉性の高い防護衣等を着用した際に生じる熱ストレスを抑制できる冷却材料に関するものである。   The present invention relates to a cooling material capable of suppressing an increase in body temperature of a human body by absorbing and evaporating sweat from the inside of the body under extreme heat, thereby efficiently depriving the heat of vaporization. Specifically, the present invention relates to a cooling material that can suppress thermal stress that occurs when a protective clothing or the like having high hermeticity is worn.

酷暑環境下で使用する冷却ベスト等については、従来から種々提案されている。例えば、冷却服の内側に冷却管を張り巡らせた冷房服等が提案されているが、衣服が各種運動により圧縮されたときの送風の阻害性等については詳細に言及されているものはない。   Various proposals have been made for cooling vests and the like for use in extreme heat. For example, a cooling garment or the like in which a cooling pipe is stretched inside the cooling garment has been proposed, but nothing has been described in detail regarding the inhibition of air blowing when the garment is compressed by various motions.

特許文献1には、薄い布帛の二重構成とした胴衣の内部に網状の中間層を挿入して通気流路とし、外皮部にはアルミニウムまたはアルミ銅の金属膜を蒸着して熱の放射と吸収の作用を防止した冷房服が例示されているが、内皮部や通気流路については特に限定された記載はない。   In Patent Document 1, a net-like intermediate layer is inserted into a double-layered vest of a thin fabric to form a ventilation flow path, and a metal film of aluminum or aluminum copper is vapor-deposited on the outer skin portion to generate heat radiation. Although the cooling clothing which prevented the effect | action of absorption is illustrated, there is no description specifically limited about an endothelium part and a ventilation flow path.

特許文献2には、服の身体側に張り巡らせた冷却管の内部に冷水もしくは低温のブラインを流す冷却服であり、送風の阻害性や身体側へ配置する生地等について考慮した記載はない。   Patent Document 2 is a cooling garment in which cold water or low-temperature brine is allowed to flow inside a cooling pipe stretched around the body side of the garment, and there is no description that considers the obstruction of ventilation or the fabric disposed on the body side.

特許文献3には、アイスパックを用いた冷却服に関する内容であり、アイスパックを使用した場合は、肌が非常に冷たくなり、また、アイスパック表面で水蒸気が結露し、皮膚に不快感をもたらすことを抑制するために、温度依存性形状記憶樹脂の多層構造体を使用し温度調節機能を持たせた冷却服に関する内容である。   Patent Document 3 relates to cooling clothing using an ice pack. When an ice pack is used, the skin becomes very cold, and water vapor condenses on the surface of the ice pack, causing discomfort to the skin. In order to suppress this, the content relates to a cooling garment using a temperature-dependent shape memory resin multilayer structure and having a temperature control function.

特許文献4には、水分移行層、空気通過層および空気遮断層とからなり、水分移行層が抗菌性の繊維からなることが例示されているが、送風の阻害性や着用感についての記載はない。   Patent Document 4 includes a moisture transfer layer, an air passage layer, and an air blocking layer, and the moisture transfer layer is exemplified by an antibacterial fiber. Absent.

特許文献5には、空気流路を確保するためのスペーサーと、スペーサーを覆う空気の漏れ難い上布及び身体側に接する空気の漏れ難い透湿性を有する下布からなる扁平マット及び送風手段を具備した冷却装置が例示されているが、肌側に配置された空気の漏れ難い扁平マットで覆われているため、体内から発散された汗を完全に処理し、蒸発潜熱を有効に利用できるとは考えにくく、スペーサーの送風阻害性についての記載もない。   Patent Document 5 includes a flat mat composed of a spacer for securing an air flow path, an upper cloth that covers the spacer and is difficult to leak air, and a lower cloth that is in contact with the body and has moisture permeability that is difficult to leak air. However, since it is covered with a flat mat that is hard to leak air placed on the skin side, it is possible to completely treat sweat released from the body and effectively use latent heat of vaporization. It is difficult to think about, and there is no description about the air blowing inhibition property of the spacer.

Therefore, it is intended to provide a cooling material that suppresses an increase in the body temperature of the human body and has a low movement inhibition property.

本発明は上記課題を解決するため、鋭意研究した結果、本発明を完成するに至った。すなわち、本発明は、以下のとおりである。
(1)少なくとも吸水特性に優れる材料(吸汗材料)と空気の流れる通気流路部とから構成される冷却材料であって、通気流路部の圧縮硬度が、1kg/φ200以上10kg/φ200以下であり、通気流路部の送風面(吸汗材料面)以外が通気性の無いカバー材料によって囲まれている冷却材料。

以下、本発明を詳細に説明する。本発明に係る吸水特性に優れる材料(吸汗材料)は、汗を吸収拡散し、放散しやすい材料が好ましく、本来疎水性であるポリエステル、ナイロン、ポリプロピレン、ポリエチレン等の合成繊維から適宜選定することが可能で、上記からなる繊維の原糸改質や表面加工により吸水拡散性、吸水速度及び放散性を向上させたもの、さらには、極細化繊維、異形断面形状繊維等を使用することも有効な手段である。また、これら繊維の混合化、複合化及び混繊した糸状からなる繊維集合体等を使用することも有効な手段となる。   Hereinafter, the present invention will be described in detail. The material excellent in water absorption characteristics (sweat-absorbing material) according to the present invention is preferably a material that absorbs and diffuses sweat and easily dissipates, and may be appropriately selected from synthetic fibers such as polyester, nylon, polypropylene, and polyethylene that are inherently hydrophobic. It is possible to improve the water diffusibility, the water absorption speed and the dissipating property by modifying the surface yarn of the above fiber and surface processing, and it is also effective to use ultrafine fibers, irregular cross-section shaped fibers, etc. Means. It is also an effective means to use a fiber aggregate or the like composed of mixed, compounded and mixed fibers of these fibers.

吸水特性に優れる材料(吸汗材料)の形状としては、通常の衣料用の織物、編物または不織布、紙のいずれでもよい。体等への密着性を考慮すると、織物と編物の形態が好ましい。更に好ましくは、伸縮性に優れる編物がより好ましい。   As a shape of the material excellent in water absorption characteristics (sweat absorbing material), any of normal woven fabric, knitted fabric or nonwoven fabric, and paper may be used. Considering the adhesion to the body and the like, the form of woven fabric and knitted fabric is preferable. More preferably, a knitted fabric excellent in stretchability is more preferable.

吸水特性に優れる材料(吸汗材料)の質量としては30g/m以上250g/m以下が好ましく、より好ましくは40g/m以上200g/m以下である。30g/m未満であると、強度が問題となる。一方、250g/mより大きくなると衣服とした際の重量や柔軟性が問題となる。 The mass of the material excellent in water absorption properties (sweat absorbing material) is preferably 30 g / m 2 or more and 250 g / m 2 or less, more preferably 40 g / m 2 or more and 200 g / m 2 or less. If it is less than 30 g / m 2 , the strength becomes a problem. On the other hand, when it becomes larger than 250 g / m 2 , the weight and flexibility when it is used as a garment becomes a problem.

吸水特性に優れる材料(吸汗材料)の吸水拡散性は、JIS L 1907の滴下法によって評価され、30μLの水滴を1cmの高さから落としたときに、完全に吸水するまでの時間であり、好ましい性能としては、10秒以下であり、より好ましくは5秒以下である。吸水時間が、10秒を超えると汗を速やかに吸い取ることが出来できず、体内から発汗した汗を有効に吸い上げることができない。   The water-absorbing diffusivity of a material excellent in water-absorbing properties (sweat-absorbing material) is evaluated by the dropping method of JIS L 1907, and is a time until water is completely absorbed when a 30 μL water droplet is dropped from a height of 1 cm. As performance, it is 10 seconds or less, More preferably, it is 5 seconds or less. If the water absorption time exceeds 10 seconds, sweat cannot be quickly absorbed, and sweat sweated from the body cannot be effectively absorbed.

吸水特性に優れる材料(吸汗材料)の吸水速度はJIS L 1907のバイレック法により評価され、水槽に10分間浸した後の毛細管現象によって水が上昇した高さによって評価され、好ましい性能としては、70mm以上であることが好ましい。より好ましくは、100mm以上である。吸水速度が、70mm未満であると、極端に水分移行性が悪い結果となる。   The water absorption speed of a material excellent in water absorption characteristics (sweat absorbing material) is evaluated by the birec method of JIS L 1907, and is evaluated by the height at which water rises by capillary action after being immersed in a water tank for 10 minutes. The above is preferable. More preferably, it is 100 mm or more. If the water absorption rate is less than 70 mm, the result is extremely poor moisture transfer.

通気流路部としては、空気の流れを確保できる材料であれば特に限定されないが、熱可塑性樹脂の3次元スプリング構造体、エステル、ナイロン、ポリプロピレン、ポリエチレン等の合成繊維モノフィラメントを用いたダブルラッセル編物等が挙げられ、使用目的に応じて適宜選定することが可能である。しかし、各種運動時や圧縮時の送風の阻害性、着用性及び加工性等を考慮すると、3次元スプリング構造体が好ましい。この通気流路部の目的は、外部から与えられる機械的な力から通気流路を確保し、送風の阻害を防止することである。   The air flow passage section is not particularly limited as long as it is a material capable of ensuring air flow, but a double raschel knitted fabric using a synthetic fiber monofilament such as a thermoplastic resin three-dimensional spring structure, ester, nylon, polypropylene, polyethylene, or the like. Can be selected as appropriate according to the purpose of use. However, a three-dimensional spring structure is preferable in consideration of airflow obstruction, wearability, and workability during various exercises and compression. The purpose of the ventilation channel is to secure the ventilation channel from the mechanical force applied from the outside and prevent airflow obstruction.

通気流路部の圧縮方向の厚みは、5mm以上70mm以下であることが好ましい。より好ましくは10mm以上50mm以下である。5mm未満であると、十分な空間を確保できず、荷重時に空気の流れを妨げる問題が発生する。一方、70mmを超えると、着用した際の装着感を損ね、冷却材料としては適さない。   The thickness of the ventilation channel in the compression direction is preferably 5 mm or more and 70 mm or less. More preferably, it is 10 mm or more and 50 mm or less. If it is less than 5 mm, a sufficient space cannot be secured, and a problem of hindering the air flow during load occurs. On the other hand, when it exceeds 70 mm, the wearing feeling at the time of wearing is impaired, and it is not suitable as a cooling material.

通気流路部の見掛け密度は、10kg/m以上100kg/m以下であることが好ましい。10kg/m未満であると、運動時や圧力が通気流路部に掛かった際に、通気流路を確保できない問題が生じる。一方で、100kg/mを超えると、上記と同様に着用した際の装着感を損ね、冷却材料としては適さない。 The apparent density of the ventilation channel is preferably 10 kg / m 3 or more and 100 kg / m 3 or less. If it is less than 10 kg / m 3 , there is a problem that the ventilation channel cannot be secured during exercise or when pressure is applied to the ventilation channel. On the other hand, when it exceeds 100 kg / m 3 , the wearing feeling when worn similarly to the above is impaired, and it is not suitable as a cooling material.

通気流路部の圧縮硬度は、1.0kg/φ200以上10kg/φ200以下であることが好ましい。1.0kg/φ200未満であると、十分な空間を確保できず、荷重時に空気の流れを妨げる問題が発生する。一方、10kg/φ200を超えると、着用した際の装着感を損ね、冷却材料としては適さない。   The compression hardness of the ventilation channel is preferably 1.0 kg / φ200 or more and 10 kg / φ200 or less. If it is less than 1.0 kg / φ200, a sufficient space cannot be secured, and a problem of hindering the air flow during loading occurs. On the other hand, if it exceeds 10 kg / φ200, the feeling of wearing when worn is impaired, and it is not suitable as a cooling material.

通気流路部の厚み方向に75%圧縮した後の回復率は、70%以上であることが好ましい。より好ましくは、80%以上である。厚み方向に75%圧縮した後の回復率が70%未満の場合には、各種運動時や荷重が掛かる状態での通気流路の確保が困難となる。   The recovery rate after compression by 75% in the thickness direction of the ventilation channel is preferably 70% or more. More preferably, it is 80% or more. If the recovery rate after compressing 75% in the thickness direction is less than 70%, it is difficult to secure a ventilation channel during various movements and under load.

通気流路部の吸水特性の優れる材料(吸汗材料)への配置形態については、特に限定されるものではない。例えば、3次元スプリング構造体及びダブルラッセル編物等を使用する場合には、送風の均一性を考慮すると、吸水特性の優れる材料面以外を空気の透過しない材料で囲い、送風の効率を上げることが有効な手段である。空気の透過しない材料とは、特に限定されないが、生地へ樹脂をラミネートもしくはコーティングした材料やフィルムが挙げられ、縫製により囲う場合には、貫通部にシール加工を施すことが、より好ましい形態である。また、通気流路部の吸水特性に優れる面側については、そのままの形態で使用することが可能であるが、通気性が確保できる補強布などで通気流路部を袋状に覆うことも可能である。   There is no particular limitation on the arrangement form of the ventilation channel portion on the material having excellent water absorption characteristics (sweat absorbing material). For example, when using a three-dimensional spring structure, a double raschel knitted fabric, etc., considering the uniformity of blowing, it is possible to increase the efficiency of blowing by surrounding the material surface with excellent water absorption characteristics with a material that does not transmit air. It is an effective means. The material that does not allow air to pass therethrough is not particularly limited, and examples thereof include a material or film obtained by laminating or coating a resin to a cloth. When the material is surrounded by sewing, it is more preferable to apply a sealing process to the penetrating portion. . In addition, the surface side of the ventilation channel that has excellent water absorption characteristics can be used as it is, but it is also possible to cover the ventilation channel in a bag shape with a reinforcing cloth that ensures air permeability. It is.

通気流路部と吸水特性の優れる材料(吸汗材料)の固定方法は、通気流路部を縫製、接着する及び通気流路部を吸汗材料と他の材料で挟み押さえ込む方法等があるが、特に限定されるものではない。通風の均一性や装着性を考慮すると、通気流路部の上から他の材料で押さえ込むことがより好ましい。   There are methods for fixing the ventilation channel part and the material having excellent water absorption characteristics (sweat absorbing material), such as sewing and bonding the ventilation channel part and holding the ventilation channel part between the sweat absorbing material and other materials. It is not limited. In consideration of the uniformity of the ventilation and the mountability, it is more preferable to hold down with another material from above the ventilation channel.

通気流路部の設置場所は、身体のいかなる部位にも装着することが可能であるが、質量や装着感等を考慮すると、冷却効果の高い部位に選択的に配置することは有効な手段である。   The installation location of the ventilation channel can be attached to any part of the body, but considering the mass and wearing feeling, it is an effective means to selectively place it in a part with a high cooling effect. is there.

通気流路部には、空気を送り込む送風口が少なくとも1個以上設置されていることが好ましい。送風の均一性等を考慮し、送風口の数は適宜設定が可能で、外部からの送風機やライン等からの空気供給が可能となる。送風口としては、空気が送風できる管であれば、特に限定されないが、装着感、重量等を考慮すると樹脂製のものが好ましい。   It is preferable that at least one air blowing port for sending air is installed in the ventilation channel. In consideration of the uniformity of air blowing, the number of air blowing ports can be set as appropriate, and air can be supplied from an external blower or line. Although it will not specifically limit if it is a pipe | tube which can blow air as a ventilation port, The thing made from resin is preferable when a mounting feeling, a weight, etc. are considered.
