【発明の属する技術分野】
本発明は、スポーツ用衣類に好適な、防風性と防水性を有し、かつ快適な保温性を持つウインドブレーカーに関するものである。
【０００２】
【従来の技術】
従来、ウインドブレーカーにおいては、防風性と軽度な防水性の付与に主眼をおいたものが主体であり、ウインドブレーカーに保温性を付与したものとしては、布帛にアルミニウム粉末等を練り込んだ樹脂をコーティングして、身体からの輻射熱を反射させ断熱性を向上させたもの、あるいは、含気率を上げた素材を用い不動空気層を作ることにより断熱性を向上させたものが用いられている。
【０００３】
しかしながら、上述の含気率を上げた素材を用いた場合はカサ高になり、着用時の運動性が阻害されるという課題があり、また、輻射熱を反射させる素材はアルミニウム等の金属の色がつき、色展開に制限があるという課題があった。
【０００４】
これらの課題を解決するものとして吸放湿吸水発熱繊維を用いた衣料が、特公平７−５９７６２号公報で提案されているが、該公報には単に吸放湿吸水発熱性繊維を使用した衣料や、それを中綿や裏地に使用した衣料の開示があるのみである。また、ここで用いられる吸放湿吸水発熱性繊維は、吸湿率が高いために、手や身体に触れたときに冷たく感じるとともに、吸放湿吸水発熱性繊維からなる衣料では、着用時に吸放湿吸水して発熱すると同時に、空気中に水蒸気を放散しているために気化熱を奪われる。吸放湿吸水発熱性繊維を用いた衣料において保温性に寄与するのは、吸放湿吸水発熱から気化熱を差し引いた熱量のみである。したがって、吸放湿吸水発熱が大きいものほど奪われる気化熱が大きいため、吸放湿吸水発熱をいくら大きくしても、保温性の向上効果は小さいという問題があった。
【０００５】
【発明が解決しようとする課題】
本発明の目的は、防風性と防水性を有するとともに、上記の実状に鑑み、水分吸着発熱による保温効果を最大限に生かし、かつ、手や身体に触れた時に冷たく感じることのないウインドブレーカーを提供することにある。
【０００６】
【課題を解決するための手段】
本発明者等は、上記課題について鋭意研究した結果、水分吸着発熱性能を有する布帛層の上に、気化熱を制御する放湿放熱抑制性能を有する布帛層として通気度が５ｃｍ3／ｃｍ2・sec以下、かつ透湿度が３，０００〜１２，０００ｇ／ｍ2・２４ｈｒの範囲にある高密度織物または合成樹脂膜積層品を表地として積層することにより、水分吸着発熱性能を効率良く発揮されるのと同時に、水分吸着発熱性能を有する裏地の接触冷感（ｑｍａｘ）を小さくすることにより肌面に接した場合に冷たく感じることがない衣料が得られることを見出し、本発明に到達した。 すなわち、上記目的を達成するために、本発明のウインドブレーカーは以下の構成を採用する。

（８）水分吸着発熱性能を有する布帛が、蓄熱剤を含有することを特徴とする前記（１）〜（７）のいずれかに記載のウインドブレーカー。
【００１２】
【発明の実施の形態】
本発明のウインドブレーカーは、耐水圧が５ｋｐａ以上であり、通気度が５cc／ｃｍ2・sec以下、かつ透湿度が３，０００〜１２，０００ｇ／ｍ2・２４ｈｒの範囲にある放湿放熱抑制性能を有する高密度織物または合成樹脂膜積層布帛を表地として使用し、裏地に水分吸着発熱性能を有する布帛を使用したウインドブレーカーであって、その水分吸着発熱性能を有する裏地の発熱エネルギー指数が５以上あり、かつ裏地表面の接触温冷感（ｑｍａｘ）が０．１Ｗ／ｃｍ2以下であることを特徴とするウインドブレーカーである。
【００１３】
本発明の放湿放熱抑制性能を有する表地および水分吸着性能を有する中地や裏地に有用な布帛としては、使用目的等に応じて適宜な布帛を用いることができるが、例を挙げると、ポリエステル繊維やポリアミド繊維、アクリル繊維の如き合成繊維、アセテート繊維の如き半合成繊維、綿や麻や羊毛の如き天然繊維を、単独でまたは２種以上を混合、交編織した織物や編物、不織布等が特に限定なく用いられる。
【００１４】
本発明における放湿放熱抑制性能とは、気化熱を制御することを目的とする性能である。一方、水分吸着発熱性能を有する中地や裏地の布帛においては、身体から不感蒸泄等により放出された水分を吸着して発熱するが、同時に布帛から系外に水分を蒸発し、気化熱を奪うため実際に着用した場合の発熱効果は小さくなる。この気化熱を制御して、小さくすることによりはじめて、着用時に実感できる発熱効果が得られる。
【００１５】
しかしながら、気化熱を制御してそれを小さくしすぎると、放湿性が小さくなり、着用時の蒸れ感が大きくなり不快なものとなる。気化熱を防ぐと同時に、着用時の蒸れ感をなくすためには、放湿放熱抑制性能を有する表地の透湿度が、ＪＩＳ Ｌ−１０９９（Ａ−１法）の測定法で３,０００〜１２,０００ｇ／ｍ2・２４ｈｒの範囲にあることが必要である。透湿度がこの範囲より低いと蒸れ感が大きくなり、また、この範囲より大きいと気化熱が大きくなり水分子吸着発熱性能が小さくなり発熱性能が実感できないものとなる。透湿度は、好ましくは４，０００〜１１，０００ｇ／ｍ2・２４ｈｒの範囲であり、より好ましくは６，０００〜１１，０００ｇ／ｍ2・２４ｈｒの範囲である。
【００１６】
透湿度を上述の範囲に制御する方法としては、カバーファクターが２０００以上の平織物または、２５００以上の綾組織織物の高密度織物の場合は、例えば、密度を高くしたり、太繊度糸を用いる等により生地厚を厚くすることにより、また、熱カレンダー処理による目つぶし加工により透湿度は低くなる。また、防水皮膜層積層品の場合は、親水性ポリウレタン、疎水性ポリウレタン、ポリテトラフロロエチレン、ポリエステル、ナイロン樹脂等の防水皮膜の皮膜素材や微多孔質皮膜、無孔質皮膜、微多孔質皮膜と無孔質皮膜の積層皮膜等の皮膜構造や、膜厚および、コーティング、ラミネート等の布帛との接着方法を選び、組み合わせることにより制御できるが、これらの方法に限定するものではない。
【００１７】
さらに表地の通気度を、ＪＩＳ Ｌ−１０９６（フラジール形法）の測定法で５ｃｍ3／ｃｍ2・sec以下にすることが必要である。通気度がこれより大きいと外気が衣服内に入り、保温性を低下させる。また、裏地や中地の水分吸着発熱性能により暖められた空気が衣服外へ流出する。
【００１８】
通気度を上述の範囲に制御する方法としては、高密度織物の場合は、例えば、密度を高くしたり、熱カレンダー処理することにより通気度を低下させることができる。また、防水皮膜積層品の場合は、微多孔質皮膜の孔径および膜厚により制御できる。通気性をゼロにしたい場合は、無孔質皮膜を用いることにより実現できるが、これらの方法に限定するものではない。
【００１９】
さらに本発明で用いられる表地は、ＪＩＳ規格Ｌ−１０９２による測定法で測定される耐水圧が、５ｋｐａ以上であることが必要である。耐水圧は、高ければ高い程、防水性の信頼性が高くなるため高い程好ましが、高くするためには、膜厚を厚くする必用があり、製造コストが高くなったり、風合いが硬くなるためウインドブレーカー用の表地としては３００ｋｐａ以下とすることが好ましい。
【００２０】
また、本発明で用いられる水分吸着発熱性能を有する裏地や中地の布帛層を構成する繊維は、好ましくは吸湿性を有する繊維であり、例えば、繊維便覧−原料編−（発行：丸善（株））の２４５ページに記載のように、吸湿性を有する繊維は、水分を吸着して発熱することが古くから知られている。本発明で用いられる水分吸着発熱性能を有する布帛層は、これらの吸湿性を有する繊維からなる布帛を使用しても良いが、望ましくは、合成繊維に吸湿ポリマー等を分散して練り込むことにより、吸湿性を向上させた繊維、例えば、ナイロンにポリビニルピロリドン等の吸湿ポリマーを錬り込み紡糸して得られた吸湿性向上ナイロン糸等や、後加工等により吸湿性のあるポリマーおよび／または吸湿性のある微粒子を繊維表面に固着させることにより、吸湿性を増加させ水分吸着発熱性能を向上した布帛が実用上好ましく用いられる。
【００２１】
さらに望ましくは、合成繊維に吸湿ポリマー等を分散して練り込むことにより、吸湿性を向上させた繊維に、後加工等により吸湿性のあるポリマーおよび／または吸湿性のある微粒子を繊維表面に固着させることにより水分子吸着発熱性能をさらに増加させた布帛を使用することが好ましい。
【００２２】
吸湿性を増加させると、手または身体に触れたときに冷たく感じ、保温衣料には適さなくなる。本発明は、この現象を防ぐために、水分吸着発熱性能を有する裏地の肌と接する面（裏地の表面）の接触温冷感（ｑｍａｘ）を０．１Ｗ／ｃｍ2以下にする必要がある。
【００２３】
接触温冷感（ｑｍａｘ）が０．１Ｗ／ｃｍ2以下の布帛は、裏地の表面側に凹凸を付け、接触面積を小さくした布帛構造にすることにより得られる。例えば、布帛を起毛加工する方法や多重重組織で接触面積を小さくする方法で得ることができる。また、接触面のみに吸湿性の低い繊維を用いた２重組織織編物等の多重組織織編物でも得られるが、本発明はこれらに限定されず、いかなる方法でも接触温冷感（ｑｍａｘ）を０．１Ｗ／ｃｍ2以下にすれば良い。
【００２４】
接触温冷感（ｑｍａｘ）は好ましくは０．０８Ｗ／ｃｍ2以下であり、より好ましくは０．０５Ｗ／ｃｍ2以下である。接触温冷感（ｑｍａｘ）は、小さければ、小さい程、温感が高くなるため好ましいが、水分吸着発熱性能を有しながら小さくするためには複雑な布帛構造にする必用があり、製造コストが高くなる等の問題が生ずることより０．０２Ｗ／ｃｍ2を下限とすることが好ましい。
【００２５】
この接触温冷感（ｑｍａｘ）は、素材表面の接触面積が小さい（凹凸がある）ほど、また吸湿率が小さい程接触温冷感（ｑｍａｘ）は小さくなる。例えば、ポリエチレンテレフタレート繊維１００％使いの起毛トリコットの起毛面は０．０４Ｗ／ｃｍ2であり、起毛されていない面は０．１０Ｗ／ｃｍ2である。また、同じポリエチレンテレフタレート繊維１００％使いの起毛トリコットを後加工で吸湿率３％にすると、起毛面の接触温冷感（ｑｍａｘ）は変化せず０．０４Ｗ／ｃｍ2であるのに対し、起毛のない面は０．１２Ｗ／ｃｍ2となる。
【００２６】
本発明の発熱エネルギー指数とは、ポリエステル繊維１００％素材と比較した水分吸着発熱エネルギーであり、ポリエステル繊維１００％素材を１とした場合の比較値である。具体的な測定法は実施例で詳細に示すが、アルコール温度計に３ｇの試料を巻き付け、３０℃、３０％ＲＨの環境で調温、調湿させた後、３０℃、９０％ＲＨの環境へ移動させた場合の吸湿時の温度上昇を経時的に観察し、横軸に時間、縦軸に温度としたグラフに３０℃から上昇し再び３０℃に復元するまでプロットし、その面積を測定するものである。
【００２７】
本発明で用いられる水分吸着発熱性能を有する布帛は、上述の発熱エネルギー指数が５以上必要である。発熱エネルギー指数が５未満では発熱効果が実感できない。発熱エネルギー指数は好ましくは８以上であり、さらに好ましくは１０以上である。
【００２８】
発熱エネルギー指数を５以上にするためには、例えば、ナイロンにポリビニルピロリドンを５重量％練り込むことにより発熱エネルギー指数が１３程度の糸が得られる。また、実施例に示したとおりポリエステル１００％素材にアクリルアミドメチルプロパンスルホン酸とＰＥＧ＃１０００ジメタクリレートの共重合物を３重量％程度付着させることにより発熱エネルギー指数が１５程度の布帛が得られる。さらには、吸湿性微粒子をバインダーで布帛に固着しても得られるし、合成繊維に親水基を有する単量体をグラフト共重合や架橋反応させた改質繊維でも得られる。本発明は、これらの手法にとらわれるものではなく、いかなる方法でも発熱エネルギー指数を５以上にすれば良い。
【００２９】
発熱エネルギー指数は、高い程好ましいが、発熱エネルギー指数を高くするためには、繊維に練り込む添加物を多くしたり、繊維表面に固着する樹脂量等を多くしたり、また、改質する単量体を多くする必用があり、製造コストが高くなったり、繊維の強度が低下することがあるため、５０以下とすることが好ましい。
【００３０】
本発明のウンイドブレーカーの表地に用いる通気度が５cc／ｃｍ2・sec以下、かつ透湿度が３，０００〜１２，０００ｇ／ｍ2・２４ｈｒの範囲にある放湿放熱抑制性能を有する布帛として、次式のカバーファクターが２，０００以上である平組織織物またはカバーファクターが２５００以上の綾組織織物に撥水加工を施し、耐水圧を５ｋｐａ以上とした高密度織物が挙げられる。
【００３１】
ＣＦ＝｛（Ｄ１）1/2×Ｍ｝＋｛（Ｄ２）1/2×Ｎ｝
ＣＦ：カバーファクター
Ｄ１：タテ糸の密度（ｄｔｅｘ）
Ｍ ：タテ糸の密度（本／２．５４ｃｍ）
Ｄ２：ヨコ糸の密度（ｄｔｅｘ）
Ｎ ：ヨコ糸の密度（本／２．５４ｃｍ）
上記の平組織織物または綾組織織物を構成するタテ糸およびヨコ糸に使用する繊維糸条は、好適には合成繊維よりなる長繊維でかつ繊度が３０〜１００ｄｔｅｘであり、単繊維繊度が０．２〜１．５ｄｔｅｘの細単糸繊度糸を用いることにより、高密度でも風合いが柔らかく、かつ通気度および透湿度を容易に目標範囲に制御できる点で望ましい。
【００３２】
カバーファクターが上述の範囲より小さくなると、通気度や透湿度が大きくなり放湿放熱抑制効果が得られなくなる。
【００３３】
カバーファクターの上限は、平組織の場合２７００を超えると製織性が低下したり、風合いが硬くなるので２７００以下とすることが好ましい。また、綾組織の場合は、２／１綾、３／１綾、４／１綾、変則綾組織等があり、組織により異なるため上限はいちがいに述べられないが、可職性限界より１０％以下程度とすることが好ましい。
【００３４】
カバーファクターを上述の範囲にするだけでは、５ｋｐａ以上の耐水圧は得られない。撥水加工を施すことにより、はじめて耐水圧性能が得られる。この撥水加工は、通常用いられているフッ素系撥水剤やシリコーン系の撥水剤をパディング−ドライ−キュアリングする方法等で繊維表面に固着すればよい。また、例えば、特開平９−１９５１６９号公報等に記載されている様な洗濯耐久性に優れた撥水処理を施すことが好ましいが、これらの方法に限定されるものではない。
【００３５】
本発明においては、また、表地に通気度が５cc／ｃｍ2・sec以下、かつ透湿度が３，０００〜１２，０００ｇ／ｍ2・２４ｈｒの範囲にした布帛の片面に合成樹脂からなる防水皮膜層を積層した耐水圧が５ｋｐａ以上の合成樹脂膜積層布帛を使用することにより、放湿放熱抑制性能が得られる。具体的には、布帛の片面にポリウレタンの湿式凝固法による微多孔膜や親水性ポリウレタンの無孔膜の単独膜や組合せ膜、またはポリテトラフルオロエチレン微多孔膜を積層した透湿防水加工品を挙げることができる。
【００３６】
これらの合成樹脂膜を積層する場合においては、通気度は比較的容易に制御できる。例えば、ポリウレタン微多孔膜の場合、特開平７−３６５５に記載がある様にポリウレタン樹脂中に、膨潤性層状ケイ酸塩の層間に第４級アンモニウムイオンを導入せしめた粘土有機複合体を分散させ湿式凝固することにより、湿式凝固で得られる微多孔膜の壁面に、さらに小さな孔が多数得られることにより透湿度が向上する。また、粘度有機複合体の変わりに無機微粒子を分散させることでも同様の効果が得られる。これらの分散量を変化させることにとり、目標の透湿度が得られる。さらにまた、親水性ポリウレタン無孔膜の場合、膜厚を薄くしたり、親水性樹脂中のポリオール成分をポリエチレングリコールやポリプロピレングリコールとして添加量を増やすことにより、親水性が増加し透湿性が向上するが、これらに限定されるものではない。
【００３７】
また、通気度については、前述した方法で制御できる。
【００３８】
本発明では、上述の如き表地に水分吸着発熱性能を有し、かつ裏地表面の接触温冷感（ｑｍａｘ）が０．１Ｗ／ｃｍ2以下である裏地を接着剤で接着積層した布帛を用いてウインドブレーカーを縫製してもよいし、上記特性を有する表地と裏地を用い重ねて積層して縫製してもよい。
【００３９】
また、表地と裏地の間に発熱エネルギー指数が５以上の布帛を挿入することにより、裏地と中地の水分吸着発熱性能が積算されより高い水分吸着発熱効果が得られる。
【００４０】
また、布帛に水分吸着発熱性能を付与する方法としては、好適には、ビニルスルホン酸、上述した一般式［I］、［II］、［III］で表される化合物の１種もしくは２種以上を含有する溶液に重合開始剤を混合した処理液を、パディング法、スプレー法、キスロールコーター、スリットコーターなどの処理方法で付与後、乾熱処理、湿熱処理、マイクロ波処理、紫外線処理等によりポリマー化して、繊維表面に固着する方法がある。ビニルスルホン酸はＰＨが低く、そのまま用いると綿やナイロンは脆化するため、予め中和したビニルスルホン酸ナトリウムを用いる。また、ビニルスルホン酸亜鉛を用いると消臭性能も付与することができる。ビニルスルホン酸としては、例えば、アクリルアミドメチルプロパンスルホン酸が水分子吸着発熱性能の点で好ましい。
【００４１】
重合開始剤としては、通常のラジカル開始剤を使用でき、例えば、過硫酸アンモニウム、過硫酸カリウム、過酸化水素などの無機系重合開始剤や、２，２’−アゾビス（２−アミディノプロパン）ジハイドロクロライド、２，２’−アゾビス（Ｎ、Ｎ−ジメチレンイソブチラミディン）ジハイドロクロライド、２−（カルバモイラゾ）イソブチロニトリルなどの有機系重合開始剤が挙げられる。また、過酸化ベンゾイル、アゾビスイソブチロニトリルなどの水不溶性重合開始剤をアニオン、ノニオン等の界面活性剤で乳化させて用いてもよい。コスト、取り扱いに容易さの点からは、過硫酸アンモニウムが好ましく用いられる。さらに、重合効率を高めるために、重合開始剤としての過酸化物と還元性物質を併用する、いわゆるレドックス開始剤を用いてもよい。この過酸化物としては、例えば、過硫酸アンモニウムや過硫酸カリウム、還元性物質としては、例えば、スルホキシル酸ナトリウムとホルマリンとの反応物やハイドロサルファイトなどが挙げられる。 処理液を繊維材料に付与する方法としては、通常用いられる手段が適用可能である。例えば、真空脱水機で処理するなどして付与量を調整することも好ましく行われる。
【００４２】
また、ポリエステル、ナイロンあるいはアクリル系などの合成繊維に対しては、製糸や製紡の段階での付与も可能である。例えば、ポリエステルフィラメントの場合、溶融紡糸法でＰＯＹ（半延伸糸）を紡糸する際、上記化合物の１種もしくは２種以上と炭素数が２５〜３３の高級炭化水素と、炭素数が３〜６の多価アルコールと炭素数が１４〜１８の脂肪酸とのエステル、炭素数が１２〜１７の脂肪酸とアミノアルコールとの反応により得られる脂肪族アミド、および水溶性シリコーン化合物から成る群から選ばれる少なくとも一種の化合物とポリオキシエチレン系界面活性剤の混合組成物を紡糸油剤とともに付与し、後の延伸工程において乾熱処理されることによって上記化合物が繊維に強固に付着し、耐洗濯性のある水分吸着発熱性能を付与することができる。
【００４３】
また、アクリル系繊維の場合は、湿式紡糸法で紡糸、延伸、水洗した後、上述の一般式［I］、［II］、［III］で表される化合物の１種もしくは２種以上を含む処理液を、好適には０．０５〜５．０重量％付着させ、乾燥緻密化処理、スチーム処理、乾燥工程を経て、繊維に強固に付着しポリエステルと同様に、耐洗濯性のある水分吸着発熱性能を付与することができる。
【００４４】
また、布帛に水分吸着発熱性能を有する布帛は、吸湿性微粒子として吸湿率の高いシリカ微粒子を用い、これをバインダーで繊維表面に固着することでも得られる。シリカ微粒子の固着量を制御することにより、目的とする水分吸着性能が得られる。
【００４５】
さらに、合成繊維に親水基を有する単量体をグラフト共重合や架橋反応させて合成繊維を改質させることによっても水分吸着発熱性能を付与することができる。例えば、特開昭５６−２４４２６号公報、特開昭５６−１３５５２７号公報あるいは特開昭６０−１７１４２号公報に開示されているように、合成繊維にアクリル酸やメタクリル酸等の酸性ビニルモノマーを繊維を構成する主鎖にグラフト共重合させた後、アクリル酸やメタクリル酸中のカルボキシル基をアルカリ金属で置換し、吸湿性を付与させてもよい。また、特開平５−１３２８５８号公報に開示されているように、アクリル繊維をヒドラジン処理して側鎖にヒドラジンとの反応により生成した窒素を含有する架橋構造と、ニトリル基の加水分解により生成した塩型カルボシル基を重合させ、吸湿性を付与させてもよい。

本発明のウインドブレーカーは、このような水分吸着発熱性能を有する布帛に、蓄熱剤を含有させることにより、より一層保温性を向上させることができる。本発明で用いられる蓄熱剤としては、好適には、液相から固相に相変換するときに吸熱し、液相から固相に相変換するときに放熱する、いわゆる潜熱を利用したものとして、パラフィンワックスやポリエチレングリコールをマイクロカプセルに封入したものや、アルミナ、ジルコニア、マグネシア等の無機化合物からなる遠赤外線放射セラミックなどを挙げることができる。中でも、相変換時の潜熱を利用したものは、マイクロカプセルへの封入剤を選ぶこと、また添加物により相変換温度が制御できることから、衣服内温度を一定に制御できる点で好ましく用いられる。
【００４９】
運動等による、発汗時には水分吸着発熱性能が大きくなる、すなわち運動により身体が暖かくなっているときに、発熱作用が大きくなることを蓄熱剤が吸熱することにより抑制し、逆に環境温度が低下し、衣服内温度が低下してきたときに蓄熱剤が放熱するため、衣服内温度を一定に制御する快適なウインドブレーカーが得られる。この様な効果を保持させるために、相変換温度（凝固温度）は、５〜３５℃とすることが好ましく、さらに好ましくは、１０〜２５℃である。

【００５１】
また、蓄熱剤を放湿放熱抑制性能を有する布帛に付与することでも、上記の効果が得られるが、好ましくは、水分吸着発熱性能を有する布帛に、蓄熱剤を含有させた方が、より高い保温効果が得られる。

BACKGROUND OF THE INVENTION
The present invention relates to a windbreaker suitable for sports clothing, having windproof and waterproof properties, and having a comfortable heat retaining property.
[0002]
[Prior art]
Conventionally, windbreakers have mainly focused on imparting windproof and mild waterproofness, and the ones that have been given heat insulation to windbreakers are made of a resin kneaded with aluminum powder or the like. A coating is used to improve heat insulation by reflecting radiant heat from the body, or one that improves heat insulation by forming a non-moving air layer using a material having an increased air content.
[0003]
However, when using the above-mentioned material with an increased air content, there is a problem that the material becomes bulky and the motility when worn is obstructed, and the material that reflects radiant heat has a color of metal such as aluminum In addition, there is a problem that there is a limit in color development.
[0004]
In order to solve these problems, a garment using moisture absorbing / releasing moisture-absorbing exothermic fibers has been proposed in Japanese Patent Publication No. 7-59762. There is only disclosure of clothing that uses it for batting and lining. In addition, the moisture-absorbing and moisture-absorbing exothermic fiber used here has a high moisture absorption rate, so it feels cold when touching the hand or body, and in clothing made of moisture-absorbing and absorbing water-absorbing exothermic fibers, At the same time it absorbs moisture and generates heat, it dissipates the heat of vaporization due to the diffusion of water vapor into the air. Only the amount of heat obtained by subtracting the heat of vaporization from the moisture absorption / release moisture absorption heat generation contributes to the heat retention in the clothing using the moisture absorption / release moisture absorption exothermic fiber. Therefore, since the heat of vaporization that is absorbed as the moisture absorption / release water absorption becomes larger, the heat of vaporization is larger, so that the heat retention improvement effect is small no matter how much the moisture absorption / release water absorption heat generation is increased.
[0005]

DETAILED DESCRIPTION OF THE INVENTION
The windbreaker of the present invention has a water pressure resistance of 5 kpa or more and an air permeability of 5 cc / cm. 2 -Sec or less and moisture permeability is 3,000 to 12,000 g / m 2 A windbreaker using a high-density woven fabric or synthetic resin film laminated fabric having a moisture release and heat-suppressing performance in the range of 24 hours as a surface and using a fabric having a moisture adsorption heat generation performance on the lining, and its moisture adsorption heat generation The heat generating energy index of the lining having performance is 5 or more, and the contact thermal sensation (qmax) of the lining surface is 0.1 W / cm 2 It is a windbreaker characterized by the following.
[0013]
As a fabric useful for the outer material having moisture release and heat dissipation suppressing performance and the middle and lining having moisture adsorption performance of the present invention, an appropriate fabric can be used according to the purpose of use. Textiles, polyamide fibers, synthetic fibers such as acrylic fibers, semi-synthetic fibers such as acetate fibers, natural fibers such as cotton, hemp and wool, woven fabrics, knitted fabrics, non-woven fabrics, etc. There is no particular limitation.
[0014]
The moisture release heat dissipation suppression performance in the present invention is performance aimed at controlling the heat of vaporization. On the other hand, in the cloth of the middle and the lining having moisture adsorption heat generation performance, the moisture released from the body due to insensitive excretion etc. is adsorbed to generate heat, but at the same time, the moisture is evaporated from the fabric to the outside of the system to generate heat of vaporization. Since it takes away, the heat generation effect when actually worn becomes small. Only when the heat of vaporization is controlled and reduced, a heat generation effect that can be realized when worn is obtained.
[0015]
However, if the heat of vaporization is controlled to make it too small, the moisture-releasing property becomes small, and the feeling of stuffiness at the time of wearing becomes large and becomes uncomfortable. In order to prevent the heat of vaporization and at the same time eliminate the feeling of stuffiness when worn, the moisture permeability of the outer surface having moisture release and heat radiation suppressing performance is 3,000 to 12 according to the measurement method of JIS L-1099 (A-1 method). , 000g / m 2 -It must be in the range of 24 hours. If the moisture permeability is lower than this range, the feeling of stuffiness increases, and if it exceeds this range, the heat of vaporization increases, the water molecule adsorption heat generation performance decreases, and the heat generation performance cannot be realized. The moisture permeability is preferably 4,000 to 11,000 g / m. 2 -It is the range of 24 hr, More preferably, it is 6,000-11,000 g / m. 2 -The range is 24 hours.
[0016]
As a method for controlling the moisture permeability within the above range, for example, in the case of a plain fabric having a cover factor of 2000 or more or a high-density fabric having a twill texture of 2500 or more, the density is increased or a thick yarn is used. The water vapor transmission rate is lowered by increasing the thickness of the dough by, for example, or by crushing by thermal calendering. In the case of waterproof film layered products, waterproof film materials such as hydrophilic polyurethane, hydrophobic polyurethane, polytetrafluoroethylene, polyester, nylon resin, microporous film, nonporous film, and microporous film Can be controlled by selecting and combining a film structure such as a laminated film of a non-porous film, a film thickness, and a method of adhesion to a fabric such as coating or lamination, but is not limited to these methods.
[0017]
Furthermore, the air permeability of the outer material is 5 cm by the measuring method of JIS L-1096 (Fragile method). Three / Cm 2 ・ It is necessary to make it below sec. If the air permeability is higher than this, outside air will enter the clothes and reduce heat retention. In addition, the air warmed by the moisture absorption heat generation performance of the lining and the inside outflows out of the clothes.
[0018]
As a method for controlling the air permeability within the above-mentioned range, in the case of a high-density fabric, for example, the air permeability can be lowered by increasing the density or by performing a thermal calendar treatment. In the case of a waterproof film laminate, it can be controlled by the pore diameter and film thickness of the microporous film. When it is desired to reduce the air permeability to zero, it can be realized by using a non-porous film, but it is not limited to these methods.
[0019]
Further, the surface material used in the present invention is required to have a water pressure resistance of 5 kpa or more measured by a measuring method according to JIS standard L-1092. The higher the water pressure resistance, the higher the waterproof reliability, so the higher the water pressure resistance, the better. However, in order to increase the water pressure, it is necessary to increase the film thickness, and the manufacturing cost increases and the texture becomes harder. Therefore, it is preferable that the surface of the windbreaker is 300 kpa or less.
[0020]
In addition, the fibers constituting the lining or middle fabric layer having moisture adsorption heat generation performance used in the present invention are preferably hygroscopic fibers, for example, Fiber Handbook-Raw Materials-(issued by Maruzen Co., Ltd.) )), As described on page 245, hygroscopic fibers have long been known to absorb moisture and generate heat. The fabric layer having moisture adsorption heat generation performance used in the present invention may use a fabric made of these hygroscopic fibers, but preferably by dispersing and kneading a hygroscopic polymer or the like into the synthetic fiber. , Hygroscopically improved fibers such as nylon yarn obtained by kneading and spinning a hygroscopic polymer such as polyvinylpyrrolidone into nylon, and polymers having hygroscopic properties and / or hygroscopicity by post-processing, etc. A fabric that has increased hygroscopicity and improved moisture adsorption heat generation performance by fixing the fine particles having the property to the fiber surface is preferably used practically.
[0021]
More desirably, a hygroscopic polymer or the like is dispersed in a synthetic fiber and kneaded to fix the hygroscopic polymer and / or hygroscopic fine particles to the fiber surface by post-processing or the like. It is preferable to use a fabric that further increases the water molecule adsorption heat generation performance.
[0022]
Increasing hygroscopicity feels cold when touching the hand or body, making it unsuitable for warm clothing. In the present invention, in order to prevent this phenomenon, the contact thermal sensation (qmax) of the surface in contact with the skin of the lining having the moisture adsorption heat generation performance (the surface of the lining) is 0.1 W / cm. 2 Must be:
[0023]
Contact thermal sensation (qmax) is 0.1 W / cm 2 The following fabrics can be obtained by providing a fabric structure with irregularities on the surface side of the lining to reduce the contact area. For example, it can be obtained by a method of raising a fabric or a method of reducing the contact area with a multi-heavy tissue. Further, although it can be obtained by a multi-tissue woven knitted fabric such as a double-tissue woven knitted fabric using fibers with low hygroscopicity only on the contact surface, the present invention is not limited to these, and the contact thermal sensation (qmax) can be improved by any method. 0.1 W / cm 2 The following should be done.
[0024]
Contact thermal sensation (qmax) is preferably 0.08 W / cm 2 Or less, more preferably 0.05 W / cm 2 It is as follows. The smaller the contact thermal sensation (qmax), the better the thermal sensation as the thermal sensation is higher. However, in order to make it smaller while having moisture adsorption heat generation performance, it is necessary to have a complicated fabric structure, and the production cost is lower. 0.02 W / cm due to problems such as high 2 Is preferably the lower limit.
[0025]
As for the contact thermal sensation (qmax), the smaller the contact area on the material surface (there is unevenness) and the smaller the moisture absorption, the smaller the thermal sensation (qmax). For example, the raised surface of a raised tricot using 100% polyethylene terephthalate fiber is 0.04 W / cm 2 The surface that is not brushed is 0.10 W / cm 2 It is. In addition, when a raised tricot using the same 100% polyethylene terephthalate fiber is post-processed to a moisture absorption rate of 3%, the contact thermal sensation (qmax) of the raised surface does not change and is 0.04 W / cm. 2 On the other hand, the surface without raising is 0.12 W / cm 2 It becomes.
[0026]
The exothermic energy index of the present invention is moisture adsorption exothermic energy compared with 100% polyester fiber material, and is a comparative value when the 100% polyester fiber material is 1. The specific measurement method will be described in detail in the Examples. A 3 g sample is wound around an alcohol thermometer, and after adjusting the temperature and humidity in an environment of 30 ° C. and 30% RH, the environment of 30 ° C. and 90% RH is obtained. The temperature rise at the time of moisture absorption when moving to is observed over time, plotted on a graph with time on the horizontal axis and temperature on the vertical axis until it rises from 30 ° C and restores again to 30 ° C, and the area is measured To do.
[0027]
The fabric having moisture adsorption heat generation performance used in the present invention needs to have a heat generation energy index of 5 or more. If the exothermic energy index is less than 5, the exothermic effect cannot be realized. The exothermic energy index is preferably 8 or more, more preferably 10 or more.
[0028]
In order to increase the exothermic energy index to 5 or more, for example, a yarn having an exothermic energy index of about 13 can be obtained by kneading 5% by weight of polyvinylpyrrolidone in nylon. Further, as shown in the examples, a fabric having an exothermic energy index of about 15 can be obtained by attaching about 3% by weight of a copolymer of acrylamidomethylpropanesulfonic acid and PEG # 1000 dimethacrylate to a 100% polyester material. Further, it can be obtained by adhering hygroscopic fine particles to a fabric with a binder, or a modified fiber obtained by graft copolymerization or crosslinking reaction of a monomer having a hydrophilic group with a synthetic fiber. The present invention is not limited to these methods, and the exothermic energy index may be 5 or more by any method.
[0029]
The higher the exothermic energy index, the better. However, in order to increase the exothermic energy index, the amount of additives kneaded into the fiber, the amount of resin adhering to the fiber surface, and the like can be increased. It is necessary to increase the quantity, and the production cost is increased, and the strength of the fiber may be decreased.
[0030]
The air permeability used for the outer surface of the windbreaker of the present invention is 5 cc / cm 2 -Sec or less and moisture permeability is 3,000 to 12,000 g / m 2 -As a fabric having a moisture release and heat dissipation suppressing performance in the range of 24 hours, a water-repellent finish is applied to a plain fabric having a cover factor of 2,000 or more or a twill fabric having a cover factor of 2500 or more, and water pressure resistance A high-density woven fabric with 5 kpa or more.
[0031]
CF = {(D1) 1/2 × M} + {(D2) 1/2 × N}
CF: Cover factor
D1: Warp yarn density (dtex)
M: density of warp yarn (main / 2.54 cm)
D2: Thread density (dtex)
N: Density of the weft (book / 2.54cm)
The fiber yarn used for the warp yarn and the weft yarn constituting the above-mentioned plain texture fabric or twill texture fabric is preferably a long fiber made of synthetic fiber and has a fineness of 30 to 100 dtex and a single fiber fineness of 0. The use of a fine single yarn fine yarn of 2 to 1.5 dtex is desirable in that the texture is soft even at high density, and the air permeability and moisture permeability can be easily controlled within the target range.
[0032]
When the cover factor is smaller than the above range, the air permeability and moisture permeability increase and the moisture release and heat dissipation suppression effect cannot be obtained.
[0033]
In the case of a plain structure, the upper limit of the cover factor is preferably 2700 or less because the weaving property is lowered or the texture becomes hard when it exceeds 2700. In addition, in the case of the twill structure, there are 2/1 twill, 3/1 twill, 4/1 twill, irregular twill structure, etc., and the upper limit is not stated because it differs depending on the structure, but 10% or less from the limit of workability It is preferable to set the degree.
[0034]
A water pressure of 5 kpa or more cannot be obtained only by setting the cover factor within the above range. The water pressure-resistant performance can be obtained for the first time by applying the water repellent treatment. This water-repellent finish may be fixed to the fiber surface by a padding-dry-curing method or the like using a commonly used fluorine-based water repellent or silicone-based water repellent. Further, for example, it is preferable to perform a water-repellent treatment excellent in washing durability as described in JP-A-9-195169, but it is not limited to these methods.
[0035]
In the present invention, the outer surface has an air permeability of 5 cc / cm. 2 -Sec or less and moisture permeability is 3,000 to 12,000 g / m 2 -By using a synthetic resin film laminated fabric having a water pressure resistance of 5 kpa or more obtained by laminating a waterproof coating layer made of a synthetic resin on one side of the fabric in a range of 24 hours, moisture release and heat radiation suppressing performance can be obtained. Specifically, a moisture-permeable and waterproof processed product in which a single membrane or a combination membrane of a polyurethane porous microporous membrane or a hydrophilic polyurethane nonporous membrane or a polytetrafluoroethylene microporous membrane is laminated on one side of a fabric. Can be mentioned.
[0036]
In the case of laminating these synthetic resin films, the air permeability can be controlled relatively easily. For example, in the case of a polyurethane microporous film, as described in JP-A-7-3655, a clay organic complex in which quaternary ammonium ions are introduced between polyurethane resin layers is dispersed in a polyurethane resin. By wet coagulation, moisture permeability is improved by obtaining many smaller pores on the wall surface of the microporous membrane obtained by wet coagulation. The same effect can be obtained by dispersing inorganic fine particles instead of the viscosity organic composite. By changing these dispersion amounts, the target moisture permeability can be obtained. Furthermore, in the case of a hydrophilic polyurethane nonporous film, the hydrophilicity is increased and the moisture permeability is improved by reducing the film thickness or increasing the amount of the polyol component in the hydrophilic resin as polyethylene glycol or polypropylene glycol. However, it is not limited to these.
[0037]
The air permeability can be controlled by the method described above.
[0038]
In the present invention, the outer surface as described above has moisture adsorption heat generation performance, and the contact thermal sensation (qmax) of the lining surface is 0.1 W / cm. 2 A windbreaker may be sewn using a fabric in which the following lining is bonded and laminated with an adhesive, or may be laminated and sewn using a surface and lining having the above characteristics.
[0039]
Further, by inserting a fabric having a heat generation energy index of 5 or more between the outer material and the lining material, the moisture adsorption heat generation performance of the lining material and the middle material is integrated, and a higher moisture adsorption heat generation effect can be obtained.
[0040]
In addition, as a method for imparting moisture adsorption heat generation performance to the fabric, preferably, vinyl sulfonic acid, one or more of the compounds represented by the above general formulas [I], [II], and [III] are used. After applying a treatment liquid in which a polymerization initiator is mixed with a solution containing a liquid by a padding method, a spray method, a kiss roll coater, a slit coater or the like, the polymer is obtained by dry heat treatment, wet heat treatment, microwave treatment, ultraviolet treatment, etc. And there is a method of fixing to the fiber surface. Vinyl sulfonic acid has a low pH, and cotton or nylon becomes brittle when used as it is, so sodium vinyl sulfonate that has been neutralized in advance is used. Moreover, when vinyl vinyl sulfonate is used, deodorizing performance can also be provided. As the vinyl sulfonic acid, for example, acrylamidomethylpropane sulfonic acid is preferable in terms of water molecule adsorption heat generation performance.
[0041]
As the polymerization initiator, a normal radical initiator can be used. For example, inorganic polymerization initiators such as ammonium persulfate, potassium persulfate, and hydrogen peroxide, and 2,2′-azobis (2-amidinopropane) di Examples thereof include organic polymerization initiators such as hydrochloride, 2,2′-azobis (N, N-dimethyleneisobutyramide) dihydrochloride, 2- (carbamoylazo) isobutyronitrile. Further, a water-insoluble polymerization initiator such as benzoyl peroxide or azobisisobutyronitrile may be used after being emulsified with a surfactant such as anion or nonion. From the viewpoint of cost and ease of handling, ammonium persulfate is preferably used. Furthermore, in order to increase the polymerization efficiency, a so-called redox initiator using a peroxide as a polymerization initiator and a reducing substance may be used. Examples of the peroxide include ammonium persulfate and potassium persulfate, and examples of the reducing substance include a reaction product of sodium sulfoxylate and formalin, hydrosulfite, and the like. As a method for applying the treatment liquid to the fiber material, commonly used means can be applied. For example, it is also preferable to adjust the application amount by processing with a vacuum dehydrator.
[0042]
In addition, it can be applied to a synthetic fiber such as polyester, nylon or acrylic at the stage of spinning or spinning. For example, in the case of a polyester filament, when POY (semi-drawn yarn) is spun by melt spinning, one or more of the above compounds, a higher hydrocarbon having 25 to 33 carbon atoms, and 3 to 6 carbon atoms are used. At least selected from the group consisting of an ester of a polyhydric alcohol and a fatty acid having 14 to 18 carbon atoms, an aliphatic amide obtained by the reaction of a fatty acid having 12 to 17 carbon atoms and an amino alcohol, and a water-soluble silicone compound A mixed composition of a kind of compound and a polyoxyethylene surfactant is applied together with a spinning oil, and the above compound adheres firmly to the fiber by a dry heat treatment in a subsequent stretching process, and has moisture resistance with washing resistance. Heat generation performance can be imparted.
[0043]
In the case of an acrylic fiber, it contains one or more of the compounds represented by the above general formulas [I], [II], and [III] after spinning, drawing and washing with a wet spinning method. The treatment liquid is preferably attached in an amount of 0.05 to 5.0% by weight, and after drying and densification treatment, steam treatment, and drying process, it adheres firmly to the fiber and, like polyester, absorbs moisture with washing resistance. Heat generation performance can be imparted.
[0044]
Further, a fabric having moisture adsorption heat generation performance on the fabric can also be obtained by using silica fine particles having a high moisture absorption rate as the hygroscopic fine particles and fixing them to the fiber surface with a binder. By controlling the amount of silica fine particles fixed, the desired moisture adsorption performance can be obtained.
[0045]
Furthermore, moisture adsorption heat generation performance can be imparted also by modifying the synthetic fiber by graft copolymerization or crosslinking reaction of a monomer having a hydrophilic group to the synthetic fiber. For example, as disclosed in JP-A-56-24426, JP-A-56-135527, or JP-A-60-17142, an acidic vinyl monomer such as acrylic acid or methacrylic acid is added to a synthetic fiber. After graft copolymerization on the main chain constituting the fiber, the carboxyl group in acrylic acid or methacrylic acid may be substituted with an alkali metal to impart hygroscopicity. Moreover, as disclosed in JP-A-5-132858, the acrylic fiber was treated with hydrazine and the side chain was produced by hydrolysis of the nitrile group with a nitrogen-containing crosslinked structure formed by reaction with hydrazine. A salt-type carbosyl group may be polymerized to impart hygroscopicity.
[0046]
As disclosed in these documents, hygroscopicity can be obtained by adding a monomer having a hydrophilic group to a synthetic fiber by graft copolymerization or a cross-linking reaction.
[0047]
In the present invention, regardless of the method described above, any method can be used to impart a monomer containing one or more hydrophilic groups to a synthetic fiber such as polyester fiber, polyamide fiber, or acrylic fiber by graft copolymerization or a crosslinking reaction. A fiber provided with adsorption heat generation performance can be used.
[0048]
The windbreaker of the present invention can further improve the heat retaining property by adding a heat storage agent to the fabric having such moisture adsorption heat generation performance. As the heat storage agent used in the present invention, preferably, it absorbs heat when phase conversion from the liquid phase to the solid phase and dissipates heat when phase conversion from the liquid phase to the solid phase. Examples include those in which paraffin wax or polyethylene glycol is encapsulated in microcapsules, and far-infrared radiation ceramics made of inorganic compounds such as alumina, zirconia, and magnesia. Among these, those utilizing the latent heat at the time of phase conversion are preferably used in that the temperature inside the clothes can be controlled to be constant since the encapsulant in the microcapsules is selected and the phase conversion temperature can be controlled by the additive.
[0049]
When sweating due to exercise, etc., moisture adsorption heat generation performance increases, that is, when the body is warm due to exercise, the heat generation effect is suppressed by the heat storage agent absorbing heat, and conversely the environmental temperature decreases. Since the heat storage agent dissipates heat when the temperature in the garment is lowered, a comfortable windbreaker that controls the temperature in the garment to be constant can be obtained. In order to maintain such effects, the phase conversion temperature (solidification temperature) is preferably 5 to 35 ° C, more preferably 10 to 25 ° C.
[0050]
As a method for fixing the heat storage agent to the fabric, the above-mentioned microcapsules and inorganic compounds are used alone and / or a mixture, and the above-mentioned polymer mainly composed of vinyl sulfonic acid is fixed to the fiber surface with a vinyl sulfonic acid solution. Although the method of mixing and the method of adhering with another binder are mentioned, it is not specifically limited in this invention.
[0051]
Moreover, the above effect can also be obtained by applying a heat storage agent to a fabric having a moisture release and heat dissipation suppression performance, but preferably, the fabric having a moisture adsorption heat generation performance is higher if the heat storage agent is contained. A heat retention effect is obtained.
[0052]
In the windbreaker application of the present invention, waterproofness may be required, and it is necessary to provide a water pressure resistance of 5 kpa or more. Moreover, the air permeability is inevitably 5 cc / cm by applying water pressure resistance. 2 ・ We can give wind resistance of less than sec.
[0053]
The windbreaker of the present invention can be used for outdoor sports wear such as fishing and mountaineering clothes, sports wear such as ski wear, athletic wear, and golf wear, casual wear, rain clothes, and outdoor work clothes.

【The invention's effect】
According to the present invention, the use of a cloth having moisture release and heat dissipation control performance as a surface material, and the use of a cloth having moisture adsorption heat generation performance for the lining material also reduces the contact thermal sensation of the contact surface of the lining surface.

That is, the fabric having moisture adsorption heat generation performance absorbs moisture generated from the body and generates heat, and at the same time, the heat of vaporization that releases moisture to the outside of the clothes is taken away. By using the moisture-absorbing heat-generating fabric of the present invention for the lining, and using a fabric having moisture-releasing and heat-suppressing performance and excellent windproof properties on the outer surface, the amount of heat generated can be substantially reduced in order to control the heat of vaporization. growing. Furthermore, since the feeling of contact cooling is kept low, a windbreaker with high heat retention can be obtained.
