Description
本発明は、表層、中間層、および裏層からなる複合構造を有し、優れた蓄熱保温性を有する蓄熱保温性衣料に関するものである。 The present invention relates to a heat storage and warming garment having a composite structure composed of a surface layer, an intermediate layer, and a back layer and having excellent heat storage and heat retention.
従来、保温性衣料として、生地厚みを厚くしたもの、生地の組織密度を上げたもの、中空繊維を用いたもの、樹脂綿を用いたものなどが知られている。しかしながら、これらは断熱性を利用したもので、人体の放熱は抑制することができるものの、低温環境下においては、十分な保温性能を維持することが困難であった。 Conventionally, as the heat-retaining garment, a fabric having a thick fabric thickness, a fabric having a higher tissue density, a fabric using hollow fibers, a fabric using resin cotton, and the like are known. However, these utilize heat insulating properties and can suppress heat dissipation of the human body, but it has been difficult to maintain sufficient heat retaining performance in a low temperature environment.
さらに近年では、保温性を高めるために赤外線吸収剤を繊維中に練りこんだり、生地表面に付着させることが提案されている（例えば特許文献１、特許文献２参照）。しかしながら、これらの保温性繊維材料で得られた被服を着用すると、太陽光に暴露されている間は高い保温性能を有するものの、屋内にはいり太陽光が届かなくなると、保温性能が低下するという問題があった。
また、特許文献３では、保温性をさらに一層高めるために、蓄熱剤が付着した蓄熱材層と断熱材層とを組合せた複合被服材料が提案されているが、その効果はまだ十分とはいえなかった。
Further, in recent years, it has been proposed to knead an infrared absorbent into a fiber or attach it to the surface of a fabric in order to improve heat retention (see, for example, Patent Document 1 and Patent Document 2). However, wearing clothing obtained from these heat-retaining fiber materials has a high heat-retaining performance while exposed to sunlight, but the heat-retaining performance is reduced when sunlight enters indoors and does not reach the sun. was there.
Further, in Patent Document 3, a composite clothing material is proposed in which a heat storage material layer to which a heat storage agent is adhered and a heat insulating material layer are combined in order to further increase the heat retention, but the effect is still sufficient. There wasn't.

本発明者らは上記課題を達成するため鋭意検討した結果、表層、中間層、および裏層で衣料を構成し、その際、表層を中空繊維からなる低通気層、中間層を保温層、裏層を蓄熱層とすることにより、蓄熱層により暖められた保温層の暖かい空気が表層から逃げにくく、同時に表層に含まれる中空繊維の空気により表層の熱伝導率が小さくなるため熱伝導による放熱も低減され、その結果、優れた蓄熱保温性が得られることを見出し、さらに鋭意検討を重ねることにより本発明を完成するに至った。 As a result of intensive studies to achieve the above-mentioned problems, the present inventors constituted clothing with a surface layer, an intermediate layer, and a back layer, in which case the surface layer is a low-breathing layer made of hollow fibers, the intermediate layer is a heat retaining layer, the back layer By making the layer a heat storage layer, the warm air of the heat retaining layer warmed by the heat storage layer is difficult to escape from the surface layer, and at the same time, the heat conductivity of the surface layer is reduced by the air of the hollow fibers contained in the surface layer, so heat dissipation due to heat conduction is also possible As a result, the present inventors have found that excellent heat storage and heat retaining properties can be obtained, and have further conducted intensive studies to complete the present invention.
かくして、本発明によれば「表層、中間層、および内層からなる複合構造を有する衣料であって、前記表層、中間層、および裏層が下記（１）〜（３）の要件を同時に満足することを特徴とする蓄熱保温性衣料。」が提供される。

以下、本発明の実施の形態について詳細に説明する。
まず、本発明の蓄熱保温性衣料は、表層、中間層、および裏層からなる複合構造を有する。ここで、表層とは、衣料を着用した際、外気側に位置する層であり、裏層とは、最も肌側に位置する層である。
Hereinafter, embodiments of the present invention will be described in detail.
First, the heat storage and warming garment of the present invention has a composite structure including a surface layer, an intermediate layer, and a back layer. Here, the surface layer is a layer located on the outside air side when wearing clothing, and the back layer is a layer located most on the skin side.
前記の表層は、少なくとも中空繊維を含む織編物からなり、該織編物の通気性が、ＪＩＳ Ｌ １０９６−１９９８、６．２７．１、Ａ（フラジール型通気性試験機法）により測定した通気性で５０ｃｃ／ｃｍ２／ｓ以下（好ましくは５〜３０ｃｃ／ｃｍ２／ｓ）である。該通気性が５０ｃｃ／ｃｍ２／ｓよりも大きいと、中間層に蓄えられた暖かい空気が表層を通して外部へ逃げてしまい、十分な蓄熱保温性が得られず好ましくない。 The surface layer is composed of a woven or knitted fabric containing at least hollow fibers, and the air permeability of the woven or knitted fabric is measured according to JIS L 1096-1998, 6.27.1, A (Fragile type air permeability test method). And 50 cc / cm 2 / s or less (preferably 5 to 30 cc / cm 2 / s). When the air permeability is higher than 50 cc / cm 2 / s, the warm air stored in the intermediate layer escapes to the outside through the surface layer, which is not preferable because sufficient heat storage and heat retaining properties cannot be obtained.
前記中空繊維としては、単糸繊維が中空を有するものであれば特に限定されず、熱伝導率が低いポリエステル、アクリル、塩化ビニルなどの合成繊維や羊毛などが例示される。なかでも、中空ポリエステル繊維が好ましい。かかる中空繊維の中空率としては５％以上（より好ましくは１５〜５０％）であることが好ましい。該中空率が５％未満では、表層の熱伝導率が大きくなり、中間層に蓄えられた熱が、熱伝導により表層を通して外部へ逃げてしまい、十分な蓄熱保温性が得られないおそれがある。逆に、該中空率が５０％よりも大きいと中空割れが発生しやすく中空繊維の製造が困難となるおそれがある。 The hollow fiber is not particularly limited as long as the single fiber has a hollow shape, and examples thereof include synthetic fibers such as polyester, acrylic, and vinyl chloride having low thermal conductivity, wool, and the like. Of these, hollow polyester fibers are preferred. The hollow ratio of such hollow fibers is preferably 5% or more (more preferably 15 to 50%). If the hollowness is less than 5%, the thermal conductivity of the surface layer increases, and the heat stored in the intermediate layer escapes to the outside through the surface layer due to thermal conduction, and there is a possibility that sufficient heat storage and heat retaining properties cannot be obtained. . On the contrary, if the hollow ratio is larger than 50%, hollow cracks are likely to occur, and it may be difficult to produce hollow fibers.
かかる中空繊維の単糸断面形状としては、中空断面であれば特に限定されず、丸中空、三角中空、四角中空などが例示される。なかでも製造の容易さの点で丸中空が好ましい。 The single fiber cross-sectional shape of the hollow fiber is not particularly limited as long as it is a hollow cross section, and examples thereof include a round hollow, a triangular hollow, and a square hollow. Among these, a round hollow is preferable in terms of ease of production.
前記中空ポリエステル繊維を形成するポリエステルは通常のものでよく、テレフタル酸を主たるジカルボン酸成分とし、少なくとも１種のグリコール、好ましくはエチレングリコール、トリメチレングリコール、テトラメチレングリコールなどから選ばれた少なくとも１種のアルキレングリコールを主たるグリコール成分とするポリエステルや、かかるポリエステルに第３成分が共重合された共重合ポリエステルが例示される。 The polyester that forms the hollow polyester fiber may be a normal one, with terephthalic acid as the main dicarboxylic acid component and at least one glycol, preferably at least one selected from ethylene glycol, trimethylene glycol, tetramethylene glycol, and the like. Examples thereof include polyesters having an alkylene glycol as a main glycol component, and copolymerized polyesters in which a third component is copolymerized with such polyester.
かかるポリエステル中には、微細孔形成剤、増粘分枝剤、艶消し剤、着色剤、各種改良剤等も必要に応じて配合されていてもよい。 In such polyester, a micropore forming agent, a thickening branching agent, a matting agent, a coloring agent, various improving agents, and the like may be blended as necessary.
前記中空繊維の形態は特に限定されず、長繊維（マルチフィラメント）でもよいし、短繊維からなる紡績糸でもよいが、防風性の点で長繊維（マルチフィラメント）であることが好ましい。単糸繊維繊度、フィラメント数、総繊度としては、各々単糸繊維繊度０．２５〜２．５ｄｔｅｘ、フィラメント数３６〜２８８本、総繊度３３〜１６７ｄｔｅｘの範囲内であることが前記の低通気性（防風性）が得られ好ましい。なお、かかる長繊維には、仮撚加工や、インターレースやタスランなどの空気加工が施されていてもよい。 The form of the hollow fiber is not particularly limited, and may be a long fiber (multifilament) or a spun yarn made of a short fiber, but is preferably a long fiber (multifilament) from the viewpoint of wind resistance. As the single yarn fiber fineness, the number of filaments, and the total fineness, the low air permeability is within the ranges of single yarn fiber fineness of 0.25 to 2.5 dtex, number of filaments of 36 to 288, and total fineness of 33 to 167 dtex. (Windproof property) is obtained and preferable. Such long fibers may be subjected to false twisting or air processing such as interlace or taslan.
前記表層を構成する前記織編物において、織編組織は特に限定されないが、平組織、綾組織、経二重織、緯二重織など通常の織組織を有する織物であって、該織物の経糸および／または緯糸に、中空繊維が配され、かつ該織物のカバーファクター（ＣＦ）が１４００以上（好ましくは２０００〜３３００）であることが好ましい。かかるカバーファクター（ＣＦ）が１４００よりも小さいと、前記の低通気性が得られないおそれがある。 In the woven or knitted fabric constituting the surface layer, the woven or knitted structure is not particularly limited, but is a woven fabric having a normal woven structure such as a plain structure, a twill structure, a warp double weave, a weft double weave, and a warp of the woven fabric. It is preferable that hollow fibers are arranged in the weft and / or the cover factor (CF) of the woven fabric is 1400 or more (preferably 2000 to 3300). When the cover factor (CF) is smaller than 1400, the low air permeability may not be obtained.
ただし、カバーファクター（ＣＦ）は下記式で表されるものである。
ＣＦ＝（ＤＷｐ／１．１）１／２×ＭＷｐ＋（ＤＷｆ／１．１）１／２×ＭＷｆ
［ＤＷｐは経糸総繊度（ｄｔｅｘ）、ＭＷｐは経糸織密度（本／２．５４ｃｍ）、ＤＷｆは緯糸総繊度（ｄｔｅｘ）、ＭＷｆは緯糸織密度（本／２．５４ｃｍ）である。］
ここで、織物の密度としては、経糸織密度で１００〜１９０本／２．５４ｃｍ、緯糸織密度で８０〜１８０本／２．５４ｃｍの範囲内であることが好ましい。
However, the cover factor (CF) is represented by the following formula.
CF = (DWp / 1.1) 1/2 × MWp + (DWf / 1.1) 1/2 × MWf
[DWp is the total warp fineness (dtex), MWp is the warp weave density (main / 2.54 cm), DWf is the total weft fineness (dtex), and MWf is the weft weave density (main / 2.54 cm). ]
Here, the density of the woven fabric is preferably in the range of 100 to 190 yarns / 2.54 cm in the warp weave density and 80 to 180 yarns / 2.54 cm in the weft weave density.
次に、中間層は、嵩高性が５〜７０ｃｍ３／ｇ（好ましくは２０〜５０ｃｍ３／ｇ）の中綿である。該嵩高性が５ｃｍ３／ｇよりも小さいと、十分な断熱性が得られず好ましくない。逆に該嵩高性が７０ｃｍ３／ｇよりも大きいと、嵩が大きすぎて着用快適性が損なわれるおそれがある。かかる中綿の目付けとしては、２０〜３００ｇ／ｍ２の範囲内であることが好ましい。厚みとしては０．５〜２０ｍｍの範囲内であることが好ましい。 Next, the intermediate layer, bulkiness 5~70cm 3 / g (preferably 20 to 50 cm 3 / g) is the batting. When the bulkiness is less than 5 cm 3 / g, it is not preferable because sufficient heat insulation cannot be obtained. On the other hand, if the bulkiness is greater than 70 cm 3 / g, the bulkiness is so large that wearing comfort may be impaired. The weight of the filling is preferably in the range of 20 to 300 g / m 2 . The thickness is preferably in the range of 0.5 to 20 mm.
かかる中綿は、ポリエステル短繊維からなることが好ましく、かかるポリエステル繊維を形成するポリエステルとしては、前記のような通常のポリエステルでよい。また、単糸繊度としては、０．６〜１００ｄｔｅｘ（より好ましくは１〜２０ｄｔｅｘ）であることが好ましく、さらには、捲縮数が３〜４０個／２５ｍｍ（好ましくは５〜３０個／２５ｍｍ）、捲縮率が３〜４０％（好ましくは５〜３０％）となるように捲縮が付与され、繊維長が３〜１００ｍｍに裁断されていることが好ましい。ポリエステル短繊維は、抗菌防臭、制菌、消臭、防ダニ、防炎などの機能を有する機能性ポリエステル繊維であってもよい。かかる中綿は、前記ポリエステル短繊維をウエブ状にしたものでもよいし、さらにアクリル酸エステル樹脂や水溶性ポリエステル樹脂などをスプレー処理し乾燥させた樹脂綿であってもよい。 Such batting is preferably made of polyester short fibers, and the polyester forming such polyester fibers may be the normal polyester as described above. The single yarn fineness is preferably 0.6 to 100 dtex (more preferably 1 to 20 dtex), and the number of crimps is 3 to 40/25 mm (preferably 5 to 30/25 mm). Further, it is preferable that crimps are applied so that the crimp rate is 3 to 40% (preferably 5 to 30%) and the fiber length is cut to 3 to 100 mm. The polyester short fiber may be a functional polyester fiber having functions such as antibacterial deodorization, bacteriostatic, deodorant, tick-proof and flameproof. Such a batting may be a web of the polyester short fiber, or may be a resin cotton obtained by spraying an acrylic ester resin or a water-soluble polyester resin and drying it.
次に、裏層は赤外線吸収剤を含む織編物である。かかる織編物を構成する繊維は特に限定されず、合成繊維、半合成繊維、天然繊維などの公知の繊維でよく、なかでも前記のようなポリエステル繊維が好ましい。単糸繊維繊度、フィラメント数、総繊度としては、各々単糸繊維繊度０．２５〜２．５ｄｔｅｘ、フィラメント数３６〜２８８本、総繊度３３〜１６７ｄｔｅｘの範囲内であることが好ましい。なお、仮撚加工や、インターレースやタスランなどの空気加工が施されていてもよい。裏層を構成する織編物の織編組織は特に限定されず通常の織編物でよい。 Next, the back layer is a woven or knitted fabric containing an infrared absorber. The fiber constituting the woven or knitted fabric is not particularly limited, and may be a known fiber such as a synthetic fiber, a semi-synthetic fiber, a natural fiber, etc. Among them, the polyester fiber as described above is preferable. As the single yarn fiber fineness, the number of filaments, and the total fineness, it is preferable that the single yarn fiber fineness is 0.25 to 2.5 dtex, the number of filaments is 36 to 288, and the total fineness is 33 to 167 dtex. Note that false twisting or air processing such as interlacing or taslan may be performed. The woven or knitted structure of the woven or knitted fabric constituting the back layer is not particularly limited, and may be a normal woven or knitted fabric.
赤外繊維吸収剤は、織編物を構成する繊維に練りこまれていてもよい。また、裏層を構成する織編物に付着していてもよい。特に裏層を構成する織編物の中間層側の面に付着していると、断熱層に含まれる空気をすばやく暖め、かかる暖かい空気が、表層と裏層との間に閉じ込められ、優れた蓄熱保温性が得られ好ましい。 The infrared fiber absorbent may be kneaded into the fibers constituting the woven or knitted fabric. Moreover, you may adhere to the woven / knitted fabric which comprises a back layer. In particular, if it adheres to the surface on the intermediate layer side of the woven or knitted fabric that constitutes the back layer, the air contained in the heat insulation layer is quickly warmed, and the warm air is trapped between the surface layer and the back layer, providing excellent heat storage. Heat retention is obtained, which is preferable.
かかる赤外線吸収剤としては、波長７００〜２５００ｎｍの赤外線に対する吸収率が１０％以上の物質であることが好ましく、炭化系・窒化系セラミックス微粒子、金属酸化物系微粒子、カーボンブラック、有機化合物の赤外線吸収色素などが例示される。なかでも、アンチモンドープ酸化錫（ＡＴＯ）やスズドープ酸化インジューム（ＩＴＯ）などの平均粒子径が１００ｎｍ以下の金属酸化物系微粒子が好ましく例示される。かかる金属酸化物系微粒子は可視光線を透過する透明な材料であり、生地本体の色相に変化を与えない点で好ましい。 The infrared absorber is preferably a substance having an absorptivity of 10% or more for infrared rays having a wavelength of 700 to 2500 nm, and infrared absorption of carbonized / nitrided ceramic fine particles, metal oxide fine particles, carbon black, and organic compounds. Examples thereof include dyes. Of these, metal oxide fine particles having an average particle diameter of 100 nm or less, such as antimony-doped tin oxide (ATO) and tin-doped indium oxide (ITO), are preferably exemplified. Such metal oxide fine particles are a transparent material that transmits visible light, and are preferable in that they do not change the hue of the fabric body.
赤外線吸収剤を織編物の表面に固着させる方法としては、例えば、赤外線吸収剤とバインダー樹脂との配合組成物を、グラビヤコーテイング法、スクリーンプリント法などの公知の付与手段で付着させた後、乾燥させる方法が好適に例示される。この際、配合組成物は水系、溶剤系のいずれで構成してもよいが、加工工程の作業環境上水系のほうが好ましい。溶剤としては、トルエン、イソプロピルアルコール、ジメチルホルムアミド、メチルエチルケトン、酢酸エチルなどが例示される。この配合組成物には、エポキシ系などの架橋剤を併用してもよい。さらに、織編物に対する付着性を向上させる等の目的で適当な添加剤をさらに配合してもよい。 As a method of fixing the infrared absorbent to the surface of the woven or knitted fabric, for example, a blended composition of the infrared absorbent and the binder resin is attached by a known application means such as a gravure coating method or a screen printing method, and then dried. The method of making it suitable is illustrated. At this time, the blended composition may be either water-based or solvent-based, but is preferably water-based in view of the working environment of the processing step. Examples of the solvent include toluene, isopropyl alcohol, dimethylformamide, methyl ethyl ketone, ethyl acetate and the like. You may use together this crosslinking composition together with crosslinking agents, such as an epoxy type. Furthermore, an appropriate additive may be further blended for the purpose of improving the adhesion to the woven or knitted fabric.
前記赤外線吸収剤とバインダー樹脂（樹脂固形分基準）との配合比率としては前者：後者で１：０．５〜１：５０（より好ましくは１：５〜１：４０）の範囲内にあることが好ましい。バインダー樹脂の配合比率が該範囲よりも小さいと、洗濯時に赤外線吸収剤が脱落する恐れがある。逆に、バインダー樹脂の配合比率を該範囲よりも多くしても、洗濯耐久性の効果はあまり変わらず経済的でない。 The blending ratio of the infrared absorber to the binder resin (resin solid content basis) is in the range of 1: 0.5 to 1:50 (more preferably 1: 5 to 1:40) in the former: latter. Is preferred. If the blending ratio of the binder resin is smaller than the above range, the infrared absorber may fall off during washing. On the contrary, even if the blending ratio of the binder resin is larger than the above range, the effect of washing durability is not changed so much and it is not economical.
前記の表層、中間層、および裏層は、必要に応じて染色加工仕上げされた後、表層が外気側、裏層が肌側となるよう縫製され、衣料となる。その際、表層、中間層、および裏層には、常法の吸水加工、撥水加工、起毛加工、さらには、紫外線遮蔽あるいは制電剤、抗菌剤、消臭剤、防虫剤、蓄光剤、再帰反射剤等の機能を付与する各種加工を付加適用してもよい。 The surface layer, the intermediate layer, and the back layer are dyed and finished as necessary, and then sewn so that the surface layer is on the outside air side and the back layer is on the skin side, thereby forming clothing. At that time, the surface layer, the intermediate layer, and the back layer have a conventional water absorption process, water repellent process, raising process, and further, an ultraviolet shielding or antistatic agent, an antibacterial agent, a deodorant, an insect repellent, a phosphorescent agent, Various processes that provide functions such as a retroreflective agent may be additionally applied.
本発明の蓄熱保温性衣料において、裏層に含まれる赤外線吸収剤が太陽光により発熱すると、中間層に蓄えられた空気が暖められる。そして、この暖かい空気は、表層から逃げにくく、同時に表層に含まれる中空繊維の空気により、表層の熱伝導率が小さくなり熱伝導による放熱も防止され、その結果、優れた蓄熱保温性が得られる。 In the heat storage and heat retaining garment of the present invention, when the infrared absorber contained in the back layer generates heat by sunlight, the air stored in the intermediate layer is warmed. And this warm air is difficult to escape from the surface layer, and at the same time, the air of the hollow fiber contained in the surface layer reduces the heat conductivity of the surface layer and prevents heat dissipation due to heat conduction, and as a result, excellent heat storage and heat retention is obtained. .
本発明の蓄熱保温性衣料は、優れた蓄熱保温性を有するので、コート、ジャケットなどの防寒用衣料や、スキー、スケート、スノーボードなどのスポーツ用衣料として好適に使用することができる。 Since the heat storage and heat retaining garment of the present invention has excellent heat storage and heat retaining properties, it can be suitably used as cold clothing such as coats and jackets, and sports clothing such as skis, skates, and snowboards.
