Description
本発明は、優れた調温効果を有する調温繊維構造物に関するものである。 The present invention relates to a temperature control fiber structure having an excellent temperature control effect.
従来から、太陽光を吸収し熱変換する衣料は、可視光線および近赤外線を吸収して熱変換する物質を、ポリマー中に練り込んで製糸した合成繊維を用いるものや、近赤外線吸収剤を、後加工で繊維表面に固着したものが知られている（特許文献１〜２参照）。 しかし、従来の太陽光吸収熱変換衣料は、太陽の放射光が照射されている間のみ布帛の表面温度が高くなり、日光が雲などにより閉ざされると、太陽光吸収熱変換効果は無くなるものである。日光が閉ざされている時こそ環境温度が低くなり、保温性の高い衣料が要求されるが、従来の太陽光吸収熱変換衣料では、太陽が出ている暖かい時により衣服内温度が高くなり、太陽が沈んだ寒い時には効果が無いのが実状であった。 Conventionally, clothing that absorbs sunlight and converts heat is a material that uses synthetic fibers kneaded into a polymer that absorbs visible light and near infrared rays to convert heat, and a near infrared absorber, The thing fixed to the fiber surface by post-processing is known (refer patent documents 1-2). However, the conventional solar-absorbing heat conversion garment has a high surface temperature of the fabric only during irradiation with solar radiation, and the sunlight absorption heat conversion effect is lost when sunlight is closed by clouds or the like. is there. When sunlight is closed, the environmental temperature is low and clothing with high heat retention is required, but in conventional solar absorption heat conversion clothing, the temperature inside the clothing becomes higher when the sun is warm, In fact, it was ineffective when the sun was cold.
この改善として、上述の方法で吸収した熱を、ポリエチレングリコールをフィルムもしくはチューブに封入し、相変換による潜熱蓄熱性を利用して蓄熱する衣料が知られている（特許文献３参照）。しかし、フィルムの間に相変換蓄熱剤を封入したものを用いた衣料は、衣料に適した風合いのものは得られていない。特に、相変換蓄熱剤が固体となった時には、とても衣料として使用できるものではないほどに硬いものであった。また、こうしたチューブに相変換蓄熱剤を封入したものを用いた衣料は、衣服内にチューブを組み込むのに煩雑な手間を要し、コスト的に高いものとなる、またチューブに一箇所でも孔ができると、相変換蓄熱剤が液体となった時に漏れる心配があった。 As this improvement, there is known a garment in which heat absorbed by the above-described method is stored in polyethylene glycol in a film or tube and stored using the latent heat storage property by phase conversion (see Patent Document 3). However, clothing using a film in which a phase change heat storage agent is sealed between films has not been obtained with a texture suitable for clothing. In particular, when the phase change heat storage agent became solid, it was so hard that it could not be used as clothing. In addition, clothing using a tube in which a phase-conversion heat storage agent is encapsulated requires complicated labor to incorporate the tube into clothing and is expensive, and there is a hole in the tube even at one location. If possible, there was a concern of leakage when the phase change heat storage agent became liquid.
一方で、ｎ−パラフィンを封入したマイクロカプセルが樹脂バインダーによって固着された蓄熱性の繊維構造物が知られている（特許文献４）。しかし、繊維構造物の使用環境や、中入れ綿の厚さまで考慮したものはなく、十分な蓄熱効果が得られるとは言えないものであった。
本発明は、かかる従来技術の背景に鑑み、優れた蓄熱性と調温効果を発揮する調温繊維構造物を提供せんとするものである。 In view of the background of such conventional technology, the present invention is intended to provide a temperature control fiber structure that exhibits excellent heat storage properties and temperature control effects.
本発明は、かかる課題を解決するために、次のような手段を採用するものである。すなわち、本発明の調温繊維構造物は、表地とポリエステル短繊維を使用した中綿と裏地とからなる繊維構造物において、該中綿が、一方の融点が、摂氏０度以上２０度未満であり、もう一方の融点が、摂氏２０度以上３５度以下である、２種類の異なる融点を持つ蓄熱性粒子を、それぞれ独立して含有し、該摂氏０度以上２０度未満の該蓄熱性粒子が、該中綿の厚さ方向の表地側１／２に分散して固着され、該摂氏２０度以上３５度以下の該蓄熱性粒子が、該中綿の厚さ方向の裏地側１／２に分散して固着されていることを特徴とするものである。 The present invention employs the following means in order to solve such problems. That is, the temperature control fiber structure of the present invention is a fiber structure composed of a filling and a lining using a surface material and polyester short fibers, and the melting point of one of the fillings is 0 degree Celsius or more and less than 20 degrees Celsius, The other melting point is 20 degrees centigrade or more and 35 degrees centigrade or less , each containing two different kinds of heat storage particles having different melting points, the heat storage particles having a melting point of 0 degrees centigrade or more and less than 20 degrees centigrade, Dispersed and fixed to the outer side 1/2 in the thickness direction of the batting, the heat storage particles of 20 degrees centigrade or more and 35 degrees or less dispersed on the lining side 1/2 in the thickness direction of the batting It is characterized by being fixed .
本発明によれば、優れた蓄熱性と調温効果を発揮する調温性衣料を提供することができる。 ADVANTAGE OF THE INVENTION According to this invention, the temperature control clothing which exhibits the outstanding heat storage property and the temperature control effect can be provided.
本発明は、前記課題、つまり優れた蓄熱性と調温効果を発揮する調温繊維構造物について、鋭意検討し、中綿に、２種類の異なる融点を持つ蓄熱性粒子を、それぞれを単独に、すなわち、独立させて、分散して固着する形で含有させてみたところ、かかる課題を一挙に解決することを究明したものであある。 The present invention is the above-described problem, that is, a temperature control fiber structure that exhibits excellent heat storage properties and temperature control effects, and intensively studied, and in the batting, each of the heat storage particles having two different melting points, That is, when it was made to contain independently and disperse | distribute and fix it, it was investigated that this subject could be solved at once.
本発明における表地と中綿と裏地からなる衣料とは、表地に合成繊維や再生繊維、天然繊維を単独もしくは混合して用いた織物、編物、不織布やそれらにウレタンやアクリル、ポリエステル等の樹脂をコーティングしたもの、また同じくウレタンやアクリル、ポリエステル等のフィルムを接着剤でラミネートしたものが用いられ、中綿にはポリエステル繊維やナイロン繊維、アクリル繊維、またウールや綿を単独もしくは混合したものが用いられ、裏地には合成繊維や再生繊維、天然繊維を単独もしくは混合して用いた織物、編物、不織布等が用いられブルゾンやパンツ等として衣料用に縫製されたものであるが、これられに限らず表地と中綿と裏地を使用した衣料であれば限定されない。 In the present invention, the garment composed of the outer material, the batting and the lining is a woven fabric, a knitted fabric, a non-woven fabric, or a resin such as urethane, acrylic, polyester, or the like, which is made of synthetic fiber, regenerated fiber, or natural fiber alone or in combination. Also, urethane, acrylic, polyester and other films laminated with adhesive are used, and batting is made of polyester fiber, nylon fiber, acrylic fiber, wool or cotton alone or mixed, The lining is made of woven fabric, knitted fabric, non-woven fabric, etc. using synthetic fibers, recycled fibers, natural fibers alone or in combination, and is sewn for clothing as blousons or pants, but is not limited to this. It is not limited as long as it is clothing that uses batting and lining.
本発明に用いる中綿は、２種類の異なる融点を持つ蓄熱性粒子を、それぞれ単独に、つまり独立した状態で、分散固着して含有させることが必要である。蓄熱性粒子は比熱の大きい金属やセラミック等の粒子を使用する、いわゆる顕熱蓄熱剤でもよいが、固体から液体に相変換するときの融解熱や凝固熱を利用する潜熱蓄熱剤が好ましく使用される。かかる２種の蓄熱性粒子をそれぞれを独立させるのは、異なる融点を有するので、一方の蓄熱性粒子の融解熱や凝固熱の影響を受けにくくするために必須の要件である。かくすることにより、それぞれの蓄熱性粒子の機能を１００％活かすことが初めてできたものである。 The batting used in the present invention needs to contain two kinds of heat storage particles having different melting points, each separately, that is, in an independent state, dispersed and fixed. The heat storage particles may be so-called sensible heat storage agents that use particles such as metals and ceramics with a large specific heat, but latent heat storage agents that use the heat of fusion or solidification heat during phase conversion from solid to liquid are preferably used. The It is an indispensable requirement to make the two kinds of heat storage particles independent from each other because they have different melting points and are less susceptible to the heat of fusion or heat of solidification of one of the heat storage particles. This is the first time that the functions of the respective heat storage particles can be fully utilized.
かかる潜熱蓄熱剤としては、トリデカン（Ｃ１３）、テトラデカン（Ｃ１４）、ペンタデカン（１５）、ヘキサデカン（Ｃ１６）、オクタデカン（Ｃ１８）等のｎ−パラフィン類や無機系共晶物および無機系水和物、カプリル酸、ラウリン酸、ステアリン酸等の脂肪酸類、炭素数１２以上の高級アルコール類、ミリスチン酸メチル、パルミチン酸メチル、ステアリン酸メチル等のエステル化合物やプリエチレングリコール等が好ましく使用されるが、これらに限定されない。かかる蓄熱剤には必要に応じて、過冷却防止剤、比重調整剤、劣化防止剤などを添加することができる。 Examples of such latent heat storage agents include n-paraffins such as tridecane (C13), tetradecane (C14), pentadecane (15), hexadecane (C16), and octadecane (C18), inorganic eutectics and inorganic hydrates, Fatty acids such as caprylic acid, lauric acid and stearic acid, higher alcohols having 12 or more carbon atoms, ester compounds such as methyl myristate, methyl palmitate and methyl stearate, and preethylene glycol are preferably used. It is not limited to. If necessary, a supercooling inhibitor, a specific gravity adjusting agent, a deterioration preventing agent and the like can be added to the heat storage agent.
本発明に用いるかかる２種類の蓄熱性粒子の融点は、一方が摂氏−１０度以上３０度以下であり、もう一方が摂氏１５度以上５０度以下であることが、衣服内を調温する観点から好ましい。さらに好ましくは、一方は摂氏０度以上２０度未満であり、もう一方は摂氏２０度以上３５度以下である。 The two melting points of the heat storage particles used in the present invention are such that one is -10 degrees C or more and 30 degrees C or less, and the other is 15 degrees C or more and 50 degrees C or less in view of adjusting the temperature in the clothes. To preferred. More preferably, one is not less than 0 degrees Celsius and less than 20 degrees Celsius, and the other is not less than 20 degrees Celsius and not more than 35 degrees Celsius.
衣料品や寝装品に用いる中綿は、保温という目的のために必要な空気層が必須であり、その保温効果は中綿の厚さに比例することは周知のことである。こうした中綿と表地、裏地で構成された衣料品や寝装品は厚みがあり、そのため、表地側と裏地側で温度差が生じる。すなわち、一般に快適と言われる衣服内温度である摂氏２５度前後から外気温度までの温度勾配が、中綿の厚さ方向に生じるのである。 It is well known that the padding used for clothing and bedding has an air layer necessary for the purpose of keeping warm, and the heat retaining effect is proportional to the thickness of the padding. Clothing and bedding made up of such batting, outer fabric, and lining have a thickness, which causes a temperature difference between the outer fabric and the lining. That is, a temperature gradient from around 25 degrees Celsius, which is generally considered comfortable, to the outside air temperature occurs in the thickness direction of the batting.
そこで、本発明では、この温度勾配に相応した融点をもつ２種類の蓄熱性粒子を中綿の厚さ方向に分散固着させることが好ましい。中綿の厚さ方向に分散固着された蓄熱性粒子は、その温度勾配に順次反応し、衣服内の温度を一定に保つ役割をするのである。 Therefore, in the present invention, it is preferable to disperse and fix two types of heat storage particles having a melting point corresponding to this temperature gradient in the thickness direction of the batting. The heat storage particles dispersed and fixed in the thickness direction of the batting successively react to the temperature gradient and play a role of keeping the temperature in the clothes constant.
さらに好ましくは、摂氏０度以上２０度未満の該蓄熱性粒子が、中綿の厚さ方向の表地側１／２に分散固着され、摂氏２０度以上３５度以下の該蓄熱性粒子が、中綿の厚さ方向の裏地側１／２に分散固着されているものである。 More preferably, the heat storage particles of 0 degree Celsius or more and less than 20 degrees Celsius are dispersed and fixed on the surface side 1/2 in the thickness direction of the cotton pad, and the heat storage particles of 20 degree Celsius or more and 35 degrees Celsius or less are It is dispersed and fixed to the lining side 1/2 in the thickness direction.
またさらには、摂氏０度以上２０度以下の該蓄熱性粒子の繊維構造物に対する総固着量の８０ｗｔ％以上が、中綿の厚さ方向の表地側１／４に分散固着され、摂氏２０度以上３５度以下の該蓄熱性粒子の繊維構造物に対する総固着量の８０ｗｔ％以上が、中綿の厚さ方向の裏地側１／４に分散固着されていることがより好ましい。 Furthermore, 80 wt% or more of the total fixing amount of the heat storage particles of 0 to 20 degrees Celsius to the fiber structure is dispersed and fixed to the outer side 1/4 in the thickness direction of the batting, and 20 degrees Celsius or more. More preferably, 80 wt% or more of the total amount of the heat storage particles of 35 degrees or less to the fiber structure is dispersed and fixed to the lining side 1/4 in the thickness direction of the batting.
従来の技術では、コーティングやプリントなどによって、片面に蓄熱材を集中して固着されたものが提案されているが、かかる方法では、中綿の厚さ方向の温度勾配に対応できないので、本発明では、表地表面温度、裏地表面温度に相応した融点の蓄熱性粒子を、表地側、裏地側それぞれに集中して（偏って）配置させたものである。かかる手段を採用することにより、表面は温度バリケードの役割をはたし、また、中綿の厚さ方向の中心に向かう温度勾配に対しても好都合に対応することができるものを容易に提供することができたものである。 In the conventional technique, a heat storage material is concentrated and fixed on one side by coating, printing, etc., but such a method cannot cope with the temperature gradient in the thickness direction of the batting. The heat storage particles having a melting point corresponding to the surface surface temperature and the lining surface temperature are concentrated (biased) on the surface side and the lining side. By adopting such means, the surface serves as a temperature barricade and can easily provide a temperature gradient toward the center in the thickness direction of the batting. Was made.
本発明で用いる前記潜熱蓄熱剤は固相−液相間を相変化する性質を有する蓄熱剤であり、相変換蓄熱剤とも呼称されるが、かかる相変換蓄熱剤は、液体になることがあるためこのままの状態で使用すると、こぼれたり、しみ出す危険があるので、マイクルカプセルに封入して使用することが好ましい。マイクロカプセルの材質としては、その耐熱温度が中綿製造工程の乾燥温度や縫製工程および着用使用時のアイロンやプレスの温度等に耐えられるものを適宜選択すればよい。例えば、メラミン樹脂、アクリル樹脂、ウレタン樹脂等が採用される。このうち特に好ましいのが耐熱性や強度に優れるメラミン樹脂である。 The latent heat storage agent used in the present invention is a heat storage agent having a property of changing the phase between a solid phase and a liquid phase, and is also referred to as a phase conversion heat storage agent, but such a phase conversion heat storage agent may become a liquid. Therefore, since there is a risk of spilling or seeping out if used in this state, it is preferable to use it in a microcapsule. As the material of the microcapsule, a material whose heat-resistant temperature can withstand the drying temperature in the filling process, the sewing process, the temperature of the iron or press at the time of wearing and the like may be appropriately selected. For example, melamine resin, acrylic resin, urethane resin or the like is employed. Among these, a melamine resin excellent in heat resistance and strength is particularly preferable.
かかるマイクルカプセルに２種の蓄熱性粒子を封入する場合も、前記のように、それぞれを独立させた状態、つまり、それぞれ別々のカプセルに封入するのが、一方の蓄熱性粒子の融解熱や凝固熱の影響を受けにくくするために必須の要件である。 In the case of encapsulating two kinds of heat storage particles in such a microcapsule, as described above, each of the heat storage particles is sealed in a state where they are independent, that is, in each capsule. This is an essential requirement to make it less susceptible to heat.
かかるマイクロカプセルの好ましい外径は０．５〜１０μｍである。外径が大きい程封入できる量が多く潜熱蓄熱量が大きくなるが、中綿に固着した場合がさついた風合いとなり衣料に適さない。また、０．５μｍより小さくなると風合い面は好ましくなるが、封入量が少なくなり蓄熱量が小さくなる。 The preferred outer diameter of such microcapsules is 0.5 to 10 μm. The larger the outer diameter, the greater the amount that can be enclosed, and the greater the amount of latent heat storage. However, when the outer diameter is fixed to the batting, the texture becomes soft and unsuitable for clothing. On the other hand, when the thickness is smaller than 0.5 μm, the texture surface is preferable, but the enclosed amount is reduced and the heat storage amount is reduced.
相変換蓄熱剤を封入するマイクロカプセルの内包量は５０〜９０％が好ましい。５０％以下では封入量が少なくなり蓄熱量が小さくなる。また、９０％以上では強度的に弱くなり、マイクロカプセルが破損する恐れがある。 The inclusion amount of the microcapsules enclosing the phase change heat storage agent is preferably 50 to 90%. If it is 50% or less, the enclosed amount decreases and the heat storage amount decreases. Further, if it is 90% or more, the strength becomes weak and the microcapsules may be damaged.
相変換蓄熱剤をマイクロカプセル化する方法としては、界面重合法、インサイチュー重合法、コアセルベート法等の従来公知の製造方法から相変換蓄熱剤およびマイクロカプセルの材質等に応じて適宜選択すればよい。 The method for microencapsulating the phase change heat storage agent may be appropriately selected from conventionally known production methods such as an interfacial polymerization method, an in situ polymerization method, a coacervate method and the like according to the material of the phase change heat storage agent and the microcapsule. .
次に相変換蓄熱剤を封入するマイクロカプセルの製造方法の一例を挙げるが、上述のとおり本法に限定されるものではない。 Next, although an example of the manufacturing method of the microcapsule which encloses a phase change thermal storage agent is given, as above-mentioned, it is not limited to this method.
メラミン粉末５ｇに３７％ホルムアルデヒド水溶液６．５ｇと水１０ｇを加え、ｐＨ８に調整した後、約摂氏７０度まで加熱してメラミン−ホルマリン初期縮合物水溶液を得た。ｐＨを４．５に調整した５％スチレン−無水マレイン酸共重合体のナトリウム塩水溶液１００ｇ中に蓄熱剤としてｎ−ヘキサタデカン（融点摂氏１８度）８０ｇを激しく撹拌しながら添加し粒子径が約２μｍになるまで乳化を行った。この乳化液に上記メラミン−ホルマリン初期縮合物水溶液全量を添加し、摂氏７０度で２時間撹拌を施した後、ｐＨを９に調整してカプセル化を終了した。得られたマイクロカプセル分散液を乾燥すればマイクロカプセルが得られるが、本分散液をバインダー樹脂溶液と混合し、中綿にスプレーし乾燥することで本発明に使用する蓄熱性粒子を含む中綿が得られる。 6.5 g of 37% formaldehyde aqueous solution and 10 g of water were added to 5 g of melamine powder, adjusted to pH 8, and heated to about 70 degrees Celsius to obtain a melamine-formalin initial condensate aqueous solution. 80 g of n-hexadecane (melting point 18 degrees Celsius) as a heat storage agent was added to 100 g of an aqueous sodium salt solution of 5% styrene-maleic anhydride copolymer adjusted to pH 4.5 while vigorously stirring, and the particle size was about 2 μm. Emulsification was carried out until. The total amount of the melamine-formalin initial condensate aqueous solution was added to this emulsion and stirred at 70 degrees Celsius for 2 hours, and then the pH was adjusted to 9 to complete encapsulation. When the obtained microcapsule dispersion is dried, microcapsules can be obtained. The dispersion is mixed with a binder resin solution, sprayed onto the batting and dried to obtain a batting containing the heat storage particles used in the present invention. It is done.
本発明に使用する中綿は、ポリエステル繊維、ナイロン繊維、アクリル繊維の如き合成繊維の短繊維やウール、綿等の天然繊維を単独もしくは混合して用いることができるが、ポリエステル短繊維が軽量で嵩高性に富み、コストも低く好ましい。また使用する短繊維の繊度も特に限定はないが、１．０〜１０ｄｔｅｘの範囲が嵩高性と風合いの観点から好ましい。１．０ｄｔｅｘ未満では柔らかすぎて所望の嵩高性が得られない。また、１０ｄｔｅｘを超えると、繊維の剛性が高すぎ風合いが硬くなる。この範囲で細い繊度の短繊維と太い繊度の短繊維を混合して用いる所謂繊度ミックスの中綿は嵩高性と風合いが両立し衣料用、寝装用の中綿として好ましい態様のひとつである。 The batting used in the present invention can be a short fiber of synthetic fiber such as polyester fiber, nylon fiber or acrylic fiber, or natural fiber such as wool or cotton, but the polyester short fiber is light and bulky. It is rich in properties and low in cost. Further, the fineness of the short fibers to be used is not particularly limited, but a range of 1.0 to 10 dtex is preferable from the viewpoint of bulkiness and texture. If it is less than 1.0 dtex, it is too soft to obtain the desired bulkiness. On the other hand, if it exceeds 10 dtex, the stiffness of the fiber is too high and the texture becomes hard. In this range, a so-called fineness mix batting using a mixture of short fibers with a fine fineness and short fibers with a large fineness is one of the preferred embodiments as a batting for clothing and bedding because both bulkiness and texture are compatible.
本発明の中綿の短繊維の接合に用いるバインダーは、アクリル樹脂、ウレタン樹脂、ポリエステル樹脂等目的に応じ任意に用いることができるが接着性と風合い、コスト面からアクリル樹脂が好ましい。また、本バインダー樹脂に相変換蓄熱剤封入マイクロカプセルを添加して中綿の繊維表面に固着する方法としてはスプレー法、含浸法、コーティング法等が挙げられるが、中でもスプレー法が、安価で風合い的にも優れ、また、蓄熱性粒子を厚さ方向に均一に固着させるには好ましい。 The binder used for joining the short fibers of the present invention can be arbitrarily used depending on the purpose, such as acrylic resin, urethane resin, polyester resin, etc., but acrylic resin is preferable from the viewpoint of adhesiveness, texture and cost. In addition, as a method for adding a phase-conversion heat storage agent-encapsulated microcapsule to the binder resin and fixing it to the fiber surface of the batting, there are a spray method, an impregnation method, a coating method, etc. Among them, the spray method is inexpensive and textured. Moreover, it is preferable for fixing the heat storage particles uniformly in the thickness direction.
相変換蓄熱剤封入マイクロカプセル等の蓄熱性粒子の固着量としては、加工後の中綿としての蓄熱量が３．０Ｊ／ｇ以上となるように固着させる必要があり、好ましくは５．０Ｊ／ｇ以上である。３．０Ｊ／ｇ未満では、着用時に蓄熱効果が実感できない。なお、蓄熱量は多ければ多い程好ましいが、蓄熱量を多くするためには、蓄熱性粒子の固着量を多くする必要がある。蓄熱性粒子の固着量を多くすると、風合いが硬くなり、衣料として適さなくなり、またコストも高価になることから、蓄熱量８０．０Ｊ／ｇ程度が衣料用の限界である。また、洗濯１０回後の中綿の蓄熱量も３．０Ｊ／ｇ以上とするのが好ましい。洗濯により蓄熱性が大幅に低下するようでは衣料として適さない。この洗濯耐久性を向上するために、蓄熱性微粒子に適したバインダー樹脂を選定することが必要である。さらに、上述の蓄熱量を３．０Ｊ／ｇ以上とするためには、顕熱蓄熱剤よりも潜熱蓄熱剤を使用した方が、熱容量が大きいため好ましい。 The amount of heat storage particles, such as phase-conversion heat storage agent-encapsulated microcapsules, should be fixed so that the heat storage amount after processing is 3.0 J / g or more, preferably 5.0 J / g. That's it. If it is less than 3.0 J / g, the heat storage effect cannot be realized at the time of wearing. In addition, although it is preferable that there is much heat storage amount, in order to increase heat storage amount, it is necessary to increase the adhesion amount of heat storage particle | grains. If the amount of the heat storage particles fixed is increased, the texture becomes hard and unsuitable as clothing, and the cost becomes high. Therefore, a heat storage amount of about 80.0 J / g is the limit for clothing. Moreover, it is preferable that the heat storage amount of the batting after washing 10 times is 3.0 J / g or more. It is not suitable as clothing if the heat storage is greatly reduced by washing. In order to improve the washing durability, it is necessary to select a binder resin suitable for the heat storage fine particles. Furthermore, in order to make the above-mentioned heat storage amount 3.0 J / g or more, it is preferable to use a latent heat storage agent rather than a sensible heat storage agent because the heat capacity is large.
本発明の中綿は、紳士服、婦人服、子供服、カジュアルウエア、フィッシングや登山衣などのアウトドアスポーツウエア、スキーウエア、ウィンドブレーカー、アスレチックウエア、ゴルフウエアなどのスポーツウエア、また、手袋、靴下、帽子など衣料品全般や、肌掛布団、枕、クッション、座布団など寝装品全般に用いることができる。 The batting of the present invention includes men's clothing, women's clothing, children's clothing, casual wear, outdoor sportswear such as fishing and climbing clothing, sportswear such as ski wear, windbreaker, athletic wear, golf wear, gloves, socks, It can be used for general clothing such as hats and bedding such as skin comforters, pillows, cushions, and cushions.
