【発明の属する技術分野】
本発明は、悪臭の付着した衣服を収納することにより、悪臭を衣服から除去するドレスカバーに関する。さらに詳しくは、衣服に付いた、タバコ臭を効果的に除去し、かつ衣服に付着したタバコ臭の飛散を防止し部屋がタバコ臭くなることを防止するドレスカバーに関する。
【０００２】
【従来の技術】
近年、一般消費者の生活レベル向上に伴い、生活空間、衣料、生活用品の臭気に対する関心が高まっている。尿臭、腐卵臭、腐魚臭、腐野菜臭に代表されるアンモニア、硫化水素、トリメチルアミン、メチルメルカプタンの４大悪臭はもちろんのこと、タバコ臭が衣服や髪に付着するといった２次的な悪臭の発生源に対しても関心が高まっている。
【０００３】
ところで、従来、ドレスカバーは、衣服をハンガーにかけた状態で、保存、収納する際、衣服が埃などで、汚れないように衣服全体に覆いかぶせる様にして使用される。この様な使用法において、ドレスカバーに用いられるシートは埃、ゴミを透過させず、ある程度柔軟であれば良く、フィルム、織物、不織布などが通常用いられている。
【０００４】
しかし、この様な従来のドレスカバーは、収納された衣服の汚れ防止機能以外の何物でもなく、本発明が課題とした、衣服に付着した悪臭の除去はできない。一方、消臭を目的としたシートは種々提案されている。従来、消臭の目的で作成されるシートは、消臭機構から分類すると、▲１▼感覚的消臭機構、▲２▼化学的脱臭機構、▲３▼物理的吸着脱臭機構、▲４▼物理化学的脱臭機構のいずれかの消臭機構を利用して加工されたものである。▲１▼感覚的消臭機構は、ａ．芳香系、ｂ．マスキング系、ｃ．中和系などがあり、いずれもシトラール、ベンジルアセテート、テレピン油等の芳香剤を用いて悪臭を感じにくくするものである。この機構は、臭気を無くすわけではなく、芳香剤を含めた何らかの臭気が残り、用途も限定される。▲２▼化学的脱臭機構は、ａ．酸化還元法、ｂ．付加縮合法、等があり、アクリル酸系化合物、フェノール系化合物、硫酸マンガンＬアスコルビン酸系化合物、イミン系化合物等が用いられ、これらの物質と悪臭物質が化学反応を起こし、無臭物質に変化、あるいは結合することによって悪臭を消すものである。この機構は、化学反応を利用するものであり、酸性の消臭剤はアルカリ性の悪臭に効果的であるといったように、消臭剤によって消臭できる臭気が限定され、タバコ臭の様な数千種の化学物質が混合した臭気は消臭できない。また、より多種の臭気を消すことを目的として、２種以上の消臭剤を混合して用いても、消臭剤どうしが反応し、（ｉ）消臭機能が損なわれる、（ｉｉ）安定した加工ができない、と言った問題が 生じる。▲３▼物理的吸着脱臭機構とは、活性炭、活性白土、セラミックス、ゼオライト、竹粉末を乾留して得られる乾留竹、の多孔質体が用いられ、多孔質体表面上の物理的な吸着機構を利用したものである。これらは、化学的脱臭機構に比較すると、幅広い臭気に対し効果を示す（実公平６−３４１０５号公報、特開平６−７３６６５号公報）。しかし、これらの物理的脱臭機構においても活性炭はアンモニア臭を除去しにくい、乾留竹は、メチルメルカプタン等腐野菜臭などを除去しにくい等、やはり臭気を限定するものであり、生活臭を含む４大悪臭（アンモニア、硫化水素、トリメチルアミン、メチルメルカプタン）、タバコ臭、等を効果的に除去できるものはない。また、乾留竹などでは、アンモニア臭等、悪臭を除去するが、竹本来の持つ臭気が強く、用途を限定せざるを得ないといった問題がある。▲４▼物理化学的脱臭機能とは、活性炭など多孔質体に酸、アルカリなど化学物質を添着したものを用い、物理的脱臭機構と化学的脱臭機構の双方を利用するものであるが、物理的消臭機構及び化学的脱臭機構の問題点を解決するものではない。
【０００５】
【発明が解決しようとする課題】
本発明は、従来のドレスカバーの性能である汚れ防止に加え、衣服に付着したタバコ臭などの悪臭を除去し、更には衣服からの悪臭の飛散を防止するという新規な性能を付与することを目的とする。
【０００６】
【課題を解決するための手段】
本発明者らは上記目的を達成するために鋭意検討した結果、消臭機能を付与した通気性シートをドレスカバーの少なくとも一部、好ましくは両面、に用いるという、悪臭発生源の存在する空間に対し消臭機能を有する通気性シートの有効面積を著しく大きく取る構造を取ることによって、衣服から飛散する悪臭物質を極めて効率的に除去しかつドレスカバー外への悪臭の飛散を防止することを見い出し、本発明に至った。また、タバコ臭といった多くの化学物質の複合臭に対しては、通気性シートの間に活性炭粉末がホットメルト剤で接着されている消臭シートを片面に、塩基性臭吸着剤を付与した通気性シートをもう片面に用いたドレスカバーによって極めて効果的に衣服に付着したタバコ臭を除去できることを見い出し、本発明に至った。つまり、活性炭粉末は塩基性臭の消臭機能が若干低いが、ある程度の塩基性臭消臭機能と酸性臭、中性臭の消臭機能を備えており、これを用いた消臭シートと、塩基性臭を集中的に除去する塩基性臭吸着剤を付与した通気性シートのそれぞれをドレスカバーの両面に用いるという構造は、従来、不可能であった極めて多くの化学物質の複合臭であるタバコ臭の除去を極めて効果的に実現できることが分かった。
【０００７】
すなわち、本発明は、
（１）通気性シート状物をその少なくとも一部に使用してなるドレスカバーであって、該通気性シート状物として、消臭剤として活性炭粉末を１０〜１００ｇ／ｍ ２ 付着させた消臭シート状物及び、塩基性臭吸着剤を０．３〜５ｇ／ｍ ２ 付着させた消臭シートが併用されていることを特徴とするドレスカバー、
（２）消臭シート状物が、シート間に活性炭粉末がホットメルト剤で固着されてなる消臭積層シートである前記１のドレスカバー。
（３）前記活性炭粉末を１０〜１００ｇ／ｍ２付着させた消臭シート状物を片面に、前記塩基性臭吸着剤が付与されてなる消臭シートをもう一方の面に使用してなる前記１または２のドレスカバー。
（４）シート間に１０〜１００ｇ／ｍ ２ の活性炭粉末が、活性炭に対する重量比で５０〜２００％の粉末ホットメルト剤で固着されてなるドレスカバー用消臭積層シート、である。以下、本発明について説明する。
【０００８】
本発明で言う、通気性シート状物とは、▲１▼ポリエチレン、ポリプロピレン、ポリエチレンテレフタレートなどに代表される樹脂フィルムの有孔シート、▲２▼紙、編み物、織物、不織布等の繊維質シート状物、及びこれら繊維質シート状物と樹脂の複合シート、▲３▼これらの積層シ−ト等がある。これらのうち、織物や不織布シートは、有効フィルムに比べ均一な通気性を有する上、紙、編み物より寸法安定性、強度が強く、特に好ましい。
【０００９】
尚、使用する繊維素材については、綿、羊毛、麻、パルプに代表される天然繊維、レーヨンなど半合成繊維、ポリエチレン、ポリプロピレン、ナイロン、ポリエステル、ポリビニルアルコールに代表される合成繊維、などいずれの繊維も使用することが出来、素材は限定されるものではない。又、不織布に関しては、スパンボンド法、スパンレース法、カードニードルパンチ法、樹脂接着法、フラッシュ紡糸法、メルトブロー法などいずれの製法で作成された不織布でもよい。スパンボンド法で製造される合繊長繊維不織布は対磨耗性、引っ張り強力など力学的な物性が高い上、通気性も高く好ましい。また、接着強力、生産性の観点から、単糸繊度は１〜１０ｄ、また目付１０〜１２０ｇ／ｍ２が好ましい。
【００１０】
本発明のドレスカバ−は上記通気性シ−ト状物をその少なくとも一部に使用してなるものである。すなわち、２枚の通気性シ−ト状物を重ね合わせて縫製したものはもちろん、通気性シ−ト状物とポリプロピレンフィルム、ポリエチレンフィルム、塩化ビニルシ−ト等の非通気性のシ−ト状物とを重ね合わせて縫製したもの、通気性シ−ト状物と非通気性のシ−ト状物からなるシ−ト状物と、通気性シ−ト状物或いは非通気性のシ−ト状物を重ね合わせて縫製したもの等があるが、消臭剤が袋内の悪臭分子を吸着することにより袋外から新鮮な空気が入る際、カバー全体から入ることが悪臭分子の濃度分布を均一にし、消臭効果が速くなる点から通気性状物はカバー全体中の５０％以上であることが好ましい。
【００１１】
また、本発明のドレスカバ−の形態は衣類全体を覆うものであれば、特に限定されるものではないが、シ−ト１枚を袋状に縫製したもの、２枚以上のシ−トを袋状に縫製したもの、又は１枚以上のシ−トを用い、片側若しくは両側に襠を設けた袋状のもの等のほか、シートを張り合わせたもの等があるが、悪臭の飛散を防止する点から、袋状のものであることが好ましい。また、カバーには必要に応じて、ファスナ−、スリット等を設けることも可能であるが、衣服に付着した悪臭の飛散を防止する点から、衣服を包んだ状態で、密閉状態を保つようにされていることが好ましい。
【００１２】
本発明のドレスカバ−は従来のドレスカバ−とは異なり、上記通気性シ−ト状物として、消臭剤を付着させた消臭シ−ト状物を用いることが肝要である。本発明における消臭剤は消臭機能を有するものをいい、
▲１▼付加縮合反応を利用したアクリル酸エステル、マレイン酸エステルなど分子内に二重結合を有する化合物やグリオキザールなど縮合作用を有する化合物、または中和、酸化還元反応を利用した有機酸系化合物などの化学的消臭剤、
▲２▼固体表面上の物理的な悪臭物質の吸着を利用した活性炭、活性白土、セラミックス、ゼオライトなどの物理吸着消臭剤、
▲３▼物理吸着消臭剤に化学的消臭剤添着させた物理化学吸着剤、
が好ましい。
【００１３】
一方、シトラール、シンナミックアルデヒドなどの芳香系消臭剤や木酢液、ベンジルアセテートなどのマスキング系消臭剤といった感覚的消臭剤は、他の臭気を飛散させることにより悪臭を感覚的に感じにくくするものであり、ドレスカバーに用いると悪臭を除去するどころか、他の臭気まで付着してしまい好ましくない。
【００１４】
上記消臭剤のうち、物理吸着消臭剤である活性炭は、化学的消臭剤が悪臭物質のイオン性や官能基によって消臭される悪臭が限定され易いのに対し、より広範囲の悪臭の吸着し、酸臭、アルカリ臭、中性臭などが多数複合したタバコ臭などの悪臭に対して効果的であり、本発明においては特に好ましい。
本発明において、消臭剤の付着量は使用する消臭剤の種類、形態等によって異なるが、好ましくは袋全体に対して０．０１〜３００ｇ／ｍ２ 、更に好ましくは０．３〜１００ｇ／ｍ２ である。
【００１５】
本発明において、消臭剤は、単一または複数の臭い成分に対して消臭機能を有する消臭剤であればよく、その形態も紛状、粒状、繊維状等いかなるものでもよい。
本発明における消臭剤は、通気性シートから脱落しない程度に支持されていれば良く、通気性シート状物上にエマルジョン系接着剤、溶剤系接着剤、ホットメルト系接着剤など通常使用される接着剤により、接着してよい。あるいは、消臭剤単独で成膜性を有する場合、接着剤を用いなくてもよい。
【００１６】
本発明において、消臭剤を付着させた消臭シ−ト状物には、消臭繊維を用いたシ−ト状物も含まれる。すなわち、例えば繊維にカルボキシル基のようなアニオン基を共重合やグラフト重合等によって導入した消臭繊維、また該アニオン基に遷移金属を付与することによって配位結合によっても消臭できるようにした消臭繊維などの、化学吸着が主たる消臭機構として消臭性能を発現させる消臭繊維を用いたシ−ト状物を使用することができる。特にアミノ基を有する化合物（好ましくはアミノ基を有する高分子化合物）を繊維に含有させたタバコ消臭繊維、さらに好ましくは、いわゆる製造後の繊維糸条や繊維布帛への後加工ではなく、ポリマー段階、原糸原綿段階で消臭機能を付与したタバコ消臭繊維を用いることは特に効果的である。このような繊維としては、例えば本出願人が先に特願平７−１６０２６４号で提案した消臭繊維（特に悪臭性のカルボニル基を含有する化合物例えばアセトアルデヒドや酸性化合物の悪臭に効果的）や特願平７−１７２５３９号で提案した消臭繊維（特にタバコ臭に効果的）が挙げられ、これらの繊維は、その大きな消臭能力と相まって臭い残りが大きく改善されるものである。これらのうち、前者（特願平７−１６０２６４号）は酸性基を繊維当たり０．０１〜２．５ｍｏｌ／ｋｇ含有する繊維にアミノ基が０．０３〜３ｍｏｌ／ｋｇ湿熱結合された消臭繊維である。含有量がこの範囲をはずれると、消臭性、取扱い性、繊維製造面に問題があり、消臭性能が不足する。なお、ここで、酸性基を含有する繊維としては、カルボキシル基、スルホン酸基などの酸性基を有するアクリル系合成繊維、モダクリル系合成繊維、セルロース系繊維が好ましい。アミノ基を湿熱結合させるには、特に好ましくはアクリル系合成繊維やモダクリル系合成繊維の製造段階において、未乾燥糸にアミノ基を有する化合物を付着させた後、湿熱処理すればよい。アミノ基を有する化合物としては、スルファニル酸、メタニル酸、オルタニル酸などがあるが２官能基以上のアミノ基を有する化合物が好ましく、硫酸ヒドロキシアミン、エチレンジアミン、ジアミノプロピルアミン等がある。特に好ましくは２官能基以上のアミノ基を有する高分子化合物がよく、ポリエチレンイミン、ポリアリルアミン、アミン変性アクリルポリマー、キトサンの一種以上がある。また、後者（特願平７−１７２５３９号）はモノマー１単位当たりのアミノ基の含有量が１〜２当量で、重合度が７〜２４００のポリマーを繊維内部に埋没した状態で０．１〜１０％ｏｗｆ含有する人造繊維と、０．２〜１０当量／ｋｇの陰イオン性官能基または該陰イオン性官能基が０．１〜５当量／ｋｇの遷移金属と結合した遷移金属塩を含有する消臭繊維である。含有量や重合度などがこの範囲をはずれると、消臭性、取扱い性、繊維製造面に問題があり、消臭性能が不足する。なお、ここで、アミノ基含有ポリマーとしては、ポリエチレンイミン、ポリアクリルアミン、アミノ変性アクリルポリマーなどの一種以上があり、アミノ基含有ポリマーを繊維内部に埋没させるには、湿式紡糸の際に、紡糸し乾燥前にディップ槽等で含浸処理する方法がある。陰イオン性官能基としては、カルボキシル基及び／又はスルホン基が好ましく、特にカルボキシル基が好ましく、カルボキシル基を含有させるには、例えばアクリル繊維をアルカリによって加水分解する、アクリル酸等のカルボキシル基含有ポリマーを共重合またはポリマーブレンド、さらには湿式紡糸後、未乾燥状態で該ポリマー水溶液に浸漬、乾燥する方法がある。遷移金属としては、銅亜鉛などがあり、遷移金属塩としては、銅化合物（ＣｕＳＯ４ 、Ｃｕ（ＮＯ３ ）２ 等）、亜鉛化合物（ＺｎＳＯ４ 、Ｚｎ（ＮＯ３ ）２ 等）が好ましい。なお、ここで、人造繊維とはキュプラ、ビスコースなどのレーヨン、アセテート、ポリエステル、アクリル等の合成繊維をいい、繊維とは、人造繊維に加えて絹、羊毛、麻などの天然繊維を包含したものである。
【００１７】
更に、本発明においては、上記の繊維の他に、化学分解あるいは物理吸着機構を主たる消臭機構とする消臭繊維を使用してもよい。化学分解を主たる消臭機構とする消臭繊維は特に限定するものではないが例えば繊維にフタロシアニン及び鉄を付与した繊維、Ｌ−アスコルビン酸及び鉄を後加工や練り混みなどにより付与した繊維などが用いることができる。また該消臭繊維自体が嵩高加工されたものであっても差し支えない。また物理吸着を主たる消臭機構とする消臭繊維としては活性炭繊維や繊維にケイ酸アルミニウムのようなセラミック粉末を後加工や練り混み等により付与した繊維などを用いることが出来る。
【００１８】
上述のとおり、本発明で使用する消臭剤としては粉末活性炭が好ましい。本発明で使用する粉末活性炭は、通常使用される椰子殻、タール、樹脂を原料とし焼成して得られる多孔質粉体を言う。特に、椰子殻を原料とし、２０〜８０メッシュに分留された活性炭は、通常のペレット状（粒径４ｍｍ）の活性炭等に対し、比表面積が大きく消臭性能の即効性の高く好ましい。
【００１９】
本発明において、消臭剤として活性炭を使用する場合、活性炭付着量は、消臭性能、生産性の面から１０〜１００ｇ／ｍ２ が好ましい。１０ｇ／ｍ２ より少ないとたとえドレスカバーの構造をとっても消臭性能が低く十分にタバコ臭を除去し得ない。一方、１００ｇ／ｍ２ より多いと消臭性能的には十分であるが、風合が著しく硬くなる上、ホットメルト剤を用いて固着させるには極めて大きな熱量を必要とし生産性に劣り、その上、縫製が著しく困難となり好ましくない。尚、活性炭の付着量は１０〜４０ｇ／ｍ２ が生産性、風合いの点でより好ましい。
【００２０】
本発明において、消臭剤として、活性炭粉末を用いた場合、通気性シ−ト状物は、通気性シート２枚の間に活性炭粉末がホットメルト剤で接着されている積層シート構造を取ることが消臭性能面、風合面から特に好ましい。
本発明で言うホットメルト剤としては、使用する通気性シートより融点の低いものを使用することができる。即ち、通常の貼り合わせ芯地の接着に使用されるポリエチレン系、酢酸ビニル系、ナイロン系、ポリエステル系、及びこれら２ 種以上の複合物などのホットメルト剤を使用できる。中でも酢酸ビニル系または、酢酸ビニル系樹脂とその他の樹脂との混合物は、融点が低いため生産効率が高く好ましい。ホットメルト剤の付着量は、使用する活性炭粉末量の重量比で５０％〜２００％とすることが好ましい。５０％より少ないと、接着不足となり活性炭粉末が固着されずシートから脱落しやすくなり、またシート裁断時などの取扱中に２枚の通気性シートが剥離するといった問題を生じる。一方、２００％より多くなると活性炭表面の大部分をホットメルト剤で覆うことになり消臭性能を損なうこととなる。また風合い、縫製の観点から、１００〜１７０％が好ましい。
【００２１】
本発明のドレスカバ−においては、活性炭だけでは塩基性臭であるアンモニアを吸着しにくい点から消臭剤として、上記の活性炭とともに塩基性臭吸収剤を併用することが好ましい。特に、たばこ臭など、生活の中で発生する悪臭はその大部分が複合臭であり、塩基性臭、酸性臭、中性臭のうち２種以上が混合している。従来の消臭性能を有する商品の殆どは、この複合臭のうち一部を除去するものであるが、本発明は、活性炭とともに塩基性臭吸収剤を併用することによって、両消臭剤の効果を損なうことなく、たばこの悪臭全体を消すことを可能にしたものである。
【００２２】
本発明で言う塩基性臭吸着剤とは、ポリアクリル酸系、マレイン酸系、多価フェノール系、酢酸金属塩、硫酸マンガン、アスコルビン酸系等の酸性化学的消臭剤、酸添着した活性炭、ゼオライト、セラミックスなどの物理化学的吸着剤をいう。つまり、タバコ臭は、ニコチン類（ピリジン、ピロールなどニコチンの変成体も含む）、アンモニア、トリメチルアミンなどの塩基性臭が比較的多く存在するため、塩基性臭吸着剤を付与した通気性シートを片面に用いることにより、より効果的に衣服に付着したタバコ臭の除去が可能となる。塩基性臭消臭剤の付着量は０．３ｇ／ｍ２ 〜５ｇ／ｍ２ が好ましい。０．３ｇ／ｍ２ 以下であるとドレスカバーの形態をとっても、消臭性能は低く十分にタバコ臭は除去されない。また、５ｇ／ｍ２ 以上となると接着剤を用いなくとも著しく風合が硬くなり、縫製が著しく困難となり好ましくない。
。
【００２３】
次に、本発明のドレスカバ−用消臭積層シ−ト及びその製造方法について説明する。本発明のドレスカバ−用消臭積層シ−トは、シート間に活性炭粉末がホットメルト剤で固着されてなる積層シートである。ここで、活性炭粉末はシート状物から脱離しない程度に支持されていればよく、活性炭粉末表面の一部がホットメルト剤により通気性シートに接合することによって支持される。即ち、得られたシートは活性炭粉末、ホットメルト剤、通気性シート状物がホットメルト剤により点接着されているために、活性炭粉末の表面が接着剤により、覆われることが少なく消臭性能高く維持したまま通気性シートに支持できる。また、この様な接合形態は、点接着であるために風合上も柔軟な消臭シートが得られる。
【００２４】
上記ドレスカバー用消臭シートは、活性炭粉末とホットメルト剤を通気性シート上に散布した後、別の通気性シート状物を重ね、熱プレスすることにより接着一体化する製造方法によって得られる。
即ち、予め、活性炭粉末、ホットメルト剤の混合粉体をホモキサー、回転型混合機など通常用いられる粉体混合機を用いて作成する。次に、接着芯地などを製造する際使用される粉体振り落とし装置によって該混合粉体を通気性シート上に散布する。更に、通気性シートを重ねた上で熱プレスロールによってホットメルト剤を軟化あるいは融解させ接着一体化させる。
【００２５】
【実施の形態】
以下に、実施例を用い、本発明を説明する。実施例中では、ことわりの無い限り全て、重量を基準とするものとする。
また、以下の方法によって官能試験を行いドレスカバー性能を評価した。
▲１▼１０畳間（４０．５ｍ３）の部屋にウール生地を用いた紳士背広を吊るし、
１６０本のタバコ（日本たばこ産業（株）製 商品名「マイルドセブン」）を燃焼させ、２時間放置する。
▲２▼紳士背広を取り出し、ドレスカバーを掛けた上で、４．５畳間（１３．１ｍ３）に吊るし、２時間放置した後、以下の方法により官能評価を行う。
▲３▼６人のモニターにタバコの臭いと告知した上で、紳士背広、４．５畳間中空気の臭気を表１の基準に従い、判別させた。また、比較として、▲１▼で取り出した直後の紳士背広の初期臭気強度および、紳士背広を入れる前の４．５畳間中の空気臭気強度、ドレスカバーを掛けずに４．５畳間に吊るし２時間放置した後紳士背広の臭気強度、４．５畳間中空気の臭気強度を表１の基準に従い判別させた。
【００２６】
【実施例１】
ポリエチレンテレフタレートを溶融紡糸して紡糸口金からエアーサッカーで牽引して、均一な長繊維ウェブを作成し、これを均一に配置された凸部を有するエンボスロールと表面が平滑な下部ロールとの間で熱圧着し、繊度２ｄ、目付３０ｇ／ｍ２、の長繊維不織布を得た。
【００２７】
次に、粒度３２〜６０メッシュに分留されたヤシガラ活性炭粉末及び粒度３０〜４０メッシュに分留された融点８３℃、メルトインデックス２０であるＥＶＡ系粉末ホットメルト剤を重量比で１：１となるように回転型粉体混合機で混合し、活性炭粉末、ホットメルト剤粉末の混合粉体を得た。次に、通常、紙や布帛にラミネートに使用される粉体散布装置を具備した熱ロール接合型のラミネート装置を用い、先に作成した長繊維不織布上に活性炭粉末とホットメルト剤粉末の合計が６０ｇ／ｍ２になるよう散布した。更に、同様の長繊維不織布を重ね、１５０℃に熱せられた熱プレスロールにて接合を行い消臭積層シートＡを得た。
【００２８】
表２に示す通り、消臭積層シートＡと先に作成した長繊維不織布を各々９０ｃｍ×６０ｃｍの長方形に切り出し、重ね合わせた上で、長方形の１長辺にファスナーを取り付けた上で、他の３辺をウェルダー型縫製機で接合し、消臭積層シートを片面に用いた袋状物を得た。更に、洋服ハンガーの引掛け部を通すために、接合した１短辺中央部に５ｃｍの切り目を入れ、ドレスカバーとし、評価に供した。
【００２９】
紳士背広臭気強度官能評価結果を表３に、４．５畳間中空気臭気強度評価結果を、表４に示す。表３及び表４より、初期臭気強度４．２であった紳士背広をカバー無しの状態で４．５畳間に吊るしておくと、紳士背広に付着していたタバコ臭の一部が部屋の空気中に飛散し、紳士背広自体の臭気強度は２．８となり、部屋の空気の臭気強度は、０から１．８まで上がっていることが分かる。これに比べ実施例１では、紳士背広自体の臭気強度は１．８であり、カバー無しの状態に比べタバコ臭が除去されていることが分かる。一方、４．５畳間中の空気臭気強度も１．１であり、カバー無しの状態に比べ紳士背広からのタバコ臭の飛散を防いでいることが分かる。
【００３０】
【実施例２】
実施例１と同様にして、目付３０ｇ／ｍ２ 、繊度２ｄの長繊維不織布を得た。
次に粒度３２〜６０メッシュに分留されたヤシガラ活性炭粉末及び粒度３０〜４０メッシュに分留された融点８３℃、メルトインデックス２０であるＥＶＡ系粉末ホットメルト剤を重量比で１：１となるように回転型粉体混合機で混合し、活性炭粉末、ホットメルト剤粉末の混合粉体を得た。次に、通常、紙や布帛にのラミネートに使用される粉体散布装置を具備した熱ロール接合型のラミネート装置を用い、先に作成した長繊維不織布上に活性炭粉末とホットメルト剤粉末の合計が６０ｇ／ｍ２になるよう散布した。更に、同様の長繊維不織布を重ね、１５０℃に熱せられた熱プレスロールにて接合を行い消臭積層シートＡを得た。
【００３１】
表２に示す通り、消臭積層シートＡと２０ｇ／ｍ２のポリプロピレンフィルムを、各々９０ｃｍ×６０ｃｍの長方形に切り出し、重ね合わせ、長方形の１長辺にファスナーを取り付けた上で、他の３辺をウェルダー型縫製機で接合し消臭積層シートを片面に用いた袋状物を得た。更に、洋服ハンガーの引掛け部を通すために、接合した１短辺中央部に５ｃｍの切り目を入れ、ドレスカバーとし、評価に供した。
【００３２】
紳士背広臭気強度官能評価結果を表３に、４．５畳間中空気臭気強度評価結果を表４に示す。表３及び表４より、実施例２では、紳士背広自体の臭気強度は、２．０であり、カバー無しの状態に比べタバコ臭が除去されていることが分かる。一方、４．５畳間中の空気臭気強度も０．５であり、カバー無しの状態に比べ紳士背広からのタバコ臭の飛散を防いでいることが分かる。４．５畳間中の空気臭気強度が、実施例１より低いレベルに抑えられているのは、ドレスカバーの片面が通気性のほとんど無いポリプロピレンフィルムであるため、フィルム面からのタバコ臭の飛散が極端に少ないためである。
【００３３】
【実施例３】
実施例１と同様にして、目付３０ｇ／ｍ２、繊度２ｄの長繊維不織布を得た。
次いで、粒度３２〜６０メッシュに分留されたヤシガラ活性炭粉末及び粒度３０〜４０メッシュに分留された融点８３℃、メルトインデックス２０であるＥＶＡ系粉末ホットメルト剤を重量比で１：１となるように回転型粉体混合機で混合し、活性炭粉末、ホットメルト剤粉末の混合粉体を得た。次に、通常、紙や布帛のラミネートに使用される粉体散布装置を具備した熱ロール接合型のラミネート装置を用い、先に作成した長繊維不織布上に活性炭粉末とホットメルト剤粉末の合計が６０ｇ／ｍ２になるよう散布した。更に、同様の長繊維不織布を重ね、１５０℃に熱せられた熱プレスロールにて接合を行い消臭積層シートＡを得た。
【００３４】
次に、ポリアクリル酸系消臭剤（ミヨシ油脂製 ＮＯＣ−Ｚｎ）の３％水溶液に先に作成した長繊維不織布を浸漬し、水溶液付着量が３０ｇ／ｍ２になるようにマングル型ロール絞り機を用い搾液した後、１５０℃で３分間乾燥し、消臭剤有効成分付着量０．９ｇ／ｍ２の消臭シートＢを得た。
表２に示す通り、消臭積層シートＡと消臭シートＢを各々９０ｃｍ×６０ｃｍの長方形に切り出し、重ね合わせ、長方形の１長辺にファスナーを取り付けた上で、他の３辺をウェルダー型縫製機で接合し消臭シートを両面に用いた袋状物を得た。更に、洋服ハンガーの引掛け部を通すために、接合した１短辺中央部に５ｃｍの切り目を入れ、ドレスカバーとし、評価に供した。
【００３５】
紳士背広臭気強度官能評価結果を表３に、４．５畳間中空気臭気強度評価結果を、表４に示す。表３及び表４より、実施例３では、紳士背広自体の臭気強度は、１．５であり、カバー無しの状態に比べ極めて効果的にタバコ臭が除去されていることが分かる。一方、４．５畳間中の空気臭気強度も１．０であり、カバー無しの状態に比べ紳士背広からのタバコ臭の飛散を防いでいることが分かる。
【００３６】

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a dress cover for removing a bad smell from clothes by storing the badly stuck clothes. More particularly, the present invention relates to a dress cover for effectively removing tobacco odor from clothes, preventing scattering of tobacco odor attached to clothes, and preventing the room from becoming tobacco odor.
[0002]
[Prior art]
2. Description of the Related Art In recent years, with the improvement in living standards of general consumers, interest in odors in living spaces, clothing, and daily necessities has increased. Ammonia, hydrogen sulfide, trimethylamine, and methyl mercaptan, which are representative of urine, rotten egg, rotten fish, and rotten vegetable smells, as well as tobacco smells attached to clothes and hair. There is increasing interest in the sources of foul odors.
[0003]
By the way, conventionally, when storing and storing clothes in a state where the clothes are hung on a hanger, the dress covers are used so as to cover the entire clothes so that the clothes are not stained with dust or the like. In such a usage, the sheet used for the dress cover only needs to be somewhat flexible without permeating dust and dirt, and a film, a woven fabric, a nonwoven fabric or the like is usually used.
[0004]
However, such a conventional dress cover has nothing other than the function of preventing the stored clothes from being stained, and cannot remove the odor adhering to the clothes, which is a problem of the present invention. On the other hand, various sheets for the purpose of deodorizing have been proposed. Conventionally, sheets created for the purpose of deodorization are classified into: (1) sensory deodorization mechanism, (2) chemical deodorization mechanism, (3) physical adsorption and deodorization mechanism, (4) physical It is processed using any deodorizing mechanism of the chemical deodorizing mechanism. (1) The sensory deodorant mechanism is a. Aromatic, b. Masking system, c. There are neutralizing systems and the like, all of which use fragrances such as citral, benzyl acetate, turpentine oil and the like to make it difficult to feel bad smell. This mechanism does not eliminate odors, but leaves some odors including fragrances, which limits its use. {Circle around (2)} The chemical deodorizing mechanism includes: a. A redox method, b. There are addition condensation methods, etc., acrylic acid compounds, phenol compounds, manganese sulfate L ascorbic acid compounds, imine compounds, etc. are used, these substances and malodorous substances cause a chemical reaction, change to odorless substances, Alternatively, the odor is eliminated by bonding. This mechanism utilizes a chemical reaction, and the odor that can be deodorized by the deodorant is limited. Odors mixed with certain chemicals cannot be eliminated. Further, even when two or more deodorants are used in combination for the purpose of eliminating more types of odors, the deodorants react with each other, and (i) the deodorant function is impaired; The problem is that it is not possible to perform the required processing. (3) The physical adsorption and deodorization mechanism uses a porous material of activated carbon, activated clay, ceramics, zeolite, and dry-distilled bamboo obtained by dry-distilling bamboo powder, and the physical adsorption mechanism on the surface of the porous material is used. It is a thing using. These have an effect on a wide range of odors as compared with the chemical deodorizing mechanism (Japanese Utility Model Publication No. 6-34105, Japanese Patent Application Laid-Open No. Hei 6-73665). However, even in these physical deodorizing mechanisms, activated carbon hardly removes the smell of ammonia, and dry-distilled bamboo hardly removes the smell of rotten vegetables such as methyl mercaptan. There is no one that can effectively remove bad odors (ammonia, hydrogen sulfide, trimethylamine, methyl mercaptan), cigarette odor, and the like. In addition, dry bamboo removes bad smells such as ammonia smell, but has a problem that the odor inherent in bamboo is strong and its use must be limited. (4) The physicochemical deodorizing function uses a porous material such as activated carbon to which a chemical substance such as an acid or an alkali is impregnated, and utilizes both a physical deodorizing mechanism and a chemical deodorizing mechanism. It does not solve the problems of the mechanical deodorizing mechanism and the chemical deodorizing mechanism.
[0005]
[Problems to be solved by the invention]
The present invention provides, in addition to the performance of a conventional dress cover, the prevention of dirt, the removal of bad smells such as tobacco odor attached to clothes, and the provision of new performance of preventing the scattering of bad smells from clothes. Aim.
[0006]
[Means for Solving the Problems]
The present inventors have conducted intensive studies to achieve the above object, and as a result, using a breathable sheet provided with a deodorizing function on at least a part of the dress cover, preferably on both sides, in a space where a malodor source exists. On the other hand, it has been found that by adopting a structure in which the effective area of the breathable sheet having a deodorizing function is made extremely large, it is possible to extremely efficiently remove odorous substances scattered from clothes and prevent odorous substances from scattering outside the dress cover. This has led to the present invention. In addition, for a complex odor of many chemical substances such as tobacco odor, a basic sheet is provided with a basic odor adsorbent on one side of a deodorizing sheet in which activated carbon powder is bonded with a hot melt agent between the air permeable sheets. The present inventors have found that a dress cover using a conductive sheet on the other side can extremely effectively remove tobacco odor from clothes. In other words, activated carbon powder has a slightly lower basic odor deodorizing function, but has a certain basic odor deodorizing function and an acidic odor, neutral odor deodorizing function, and a deodorant sheet using this, The structure in which each of the breathable sheets provided with the basic odor adsorbent for intensively removing the basic odor is used on both sides of the dress cover is a complex odor of an extremely large number of chemical substances, which was impossible in the past. It has been found that the removal of tobacco odor can be realized very effectively.
[0007]
That is, the present invention
(1) A dress cover using at least a part of a breathable sheet material, wherein the breathable sheet material is a deodorant.Activated carbon powder as 10 to 100 g / m 2 Deodorant sheet attachedAnd a basic odor adsorbent of 0.3 to 5 g / m 2 The attached deodorant sheet is also usedA dress cover,

(4) Between sheets10 to 100 g / m 2 ofActivated carbon powder50-200% powder by weight based on activated carbonA deodorant laminated sheet for a dress cover, which is fixed with a hot melt agent. Hereinafter, the present invention will be described.
[0008]
The air-permeable sheet material referred to in the present invention includes: (1) a perforated sheet of a resin film represented by polyethylene, polypropylene, polyethylene terephthalate, etc .; and (2) a fibrous sheet material such as paper, knit, woven or non-woven fabric. Products, composite sheets of these fibrous sheet materials and resins, and (3) laminated sheets of these. Among them, a woven or nonwoven fabric sheet is particularly preferable because it has uniform air permeability as compared with an effective film, and has higher dimensional stability and strength than paper and knitted fabric.
[0009]
The fiber material used is any fiber such as natural fibers such as cotton, wool, hemp and pulp, semi-synthetic fibers such as rayon, and synthetic fibers such as polyethylene, polypropylene, nylon, polyester and polyvinyl alcohol. Can also be used, and the material is not limited. As for the nonwoven fabric, a nonwoven fabric prepared by any of a spunbonding method, a spunlace method, a card needle punching method, a resin bonding method, a flash spinning method, and a melt blowing method may be used. Synthetic long-fiber nonwoven fabrics produced by the spunbonding method have high mechanical properties such as abrasion resistance and tensile strength, and also have high air permeability and are preferred. In addition, from the viewpoint of adhesive strength and productivity, the single yarn fineness is 1 to 10 d, and the basis weight is 10 to 120 g / m.2Is preferred.
[0010]
The dress cover of the present invention uses the above-mentioned air-permeable sheet for at least a part thereof. That is, not only a breathable sheet but also a non-breathable sheet such as a polypropylene film, a polyethylene film, a vinyl chloride sheet, or the like, as well as a sheet formed by overlapping two pieces of a breathable sheet. Sewn on top of each other, a sheet consisting of a breathable sheet and a non-breathable sheet, a breathable sheet or a non-breathable sheet There are some products that are sewn together by overlapping them, but when fresh air enters from outside the bag due to the deodorant adsorbing the odor molecules in the bag, the concentration distribution of the odor molecules may enter from the entire cover. It is preferable that the air permeable material accounts for 50% or more of the entire cover from the viewpoint of uniformity and speed of the deodorizing effect.
[0011]
The form of the dress cover of the present invention is not particularly limited as long as it covers the entire garment, but one sheet is sewn in a bag shape, and two or more sheets are sewn in a bag. In addition to sewn sheets or bags using one or more sheets and provided with a gore on one or both sides, there are also sheets bonded together, etc. Therefore, it is preferably a bag-like one. If necessary, the cover may be provided with fasteners, slits, and the like.However, in order to prevent the odor attached to the clothes from being scattered, the clothes should be kept in a sealed state with the clothes wrapped. It is preferred that
[0012]
In the dress cover of the present invention, unlike the conventional dress cover, it is important to use a deodorant sheet to which a deodorant is attached as the above-mentioned breathable sheet. The deodorant in the present invention refers to one having a deodorizing function,
{Circle around (1)} A compound having a double bond in a molecule such as an acrylate ester or a maleate ester utilizing an addition condensation reaction, a compound having a condensation action such as glyoxal, or an organic acid-based compound utilizing a neutralization or oxidation-reduction reaction. Chemical deodorant,
(2) Physically adsorbed deodorant such as activated carbon, activated clay, ceramics, zeolite, etc. utilizing the physical adsorption of malodorous substances on the solid surface;
(3) a physicochemical adsorbent obtained by impregnating a chemical deodorant with a physical adsorption deodorant;
Is preferred.
[0013]
On the other hand, sensory deodorants such as aromatic deodorants such as citral and cinnamamic aldehyde and masking deodorants such as wood vinegar and benzyl acetate disperse other odors, making it difficult to sense odors sensuously. If it is used for a dress cover, it will not only remove bad odors but also adhere to other odors, which is not preferable.
[0014]
Among the above deodorants, activated carbon, which is a physical adsorption deodorant, has a chemical deodorant whose odor which is deodorized by the ionicity or functional group of the odorous substance is easily limited. It is effective against bad odors such as tobacco odor, which is adsorbed and complexed with a large number of acid odor, alkali odor, neutral odor and the like, and is particularly preferable in the present invention.
In the present invention, the amount of the deodorant adhered depends on the type and form of the deodorant used, but is preferably 0.01 to 300 g / m3 with respect to the whole bag.2, More preferably 0.3 to 100 g / m2It is.
[0015]
In the present invention, the deodorant may be any deodorant having a deodorizing function for a single or a plurality of odor components, and may be in any form such as powder, granule, or fiber.
The deodorant in the present invention only needs to be supported to such an extent that it does not fall off from the air permeable sheet, and is usually used on the air permeable sheet like an emulsion adhesive, a solvent adhesive, a hot melt adhesive or the like. It may be adhered by an adhesive. Alternatively, when the deodorant alone has a film forming property, an adhesive may not be used.
[0016]
In the present invention, the deodorant sheet to which the deodorant is attached includes a sheet using deodorant fibers. That is, for example, a deodorizing fiber in which an anionic group such as a carboxyl group is introduced into the fiber by copolymerization, graft polymerization, or the like, or a deodorizing fiber in which a transition metal is imparted to the anionic group so that it can be deodorized by coordination bonds. Sheets using deodorizing fibers such as odor fibers that exhibit deodorizing performance as a main deodorizing mechanism by chemical adsorption can be used. In particular, tobacco deodorant fibers containing a compound having an amino group (preferably a high molecular compound having an amino group) in the fiber, more preferably a post-process to a so-called manufactured fiber yarn or fiber cloth, but not to a polymer fiber It is particularly effective to use tobacco deodorant fibers provided with a deodorant function at the stage and at the raw yarn stage. Examples of such fibers include deodorant fibers proposed by the present applicant in Japanese Patent Application No. Hei 7-160264 (especially effective against malodor of compounds having a malodorous carbonyl group, such as acetaldehyde and acidic compounds). Deodorizing fibers (especially effective for tobacco odor) proposed in Japanese Patent Application No. 7-172539 are mentioned, and these fibers, combined with their large deodorizing ability, greatly improve odor remaining. Among them, the former (Japanese Patent Application No. Hei 7-160264) is a deodorant fiber in which an amino group is wet-heat-bonded to a fiber containing 0.01 to 2.5 mol / kg of an acidic group and 0.03 to 3 mol / kg of an amino group. It is. If the content is out of this range, there are problems in deodorizing properties, handling properties, and fiber production, and the deodorizing performance is insufficient. Here, as the fiber containing an acidic group, an acrylic synthetic fiber, a modacrylic synthetic fiber, or a cellulosic fiber having an acidic group such as a carboxyl group or a sulfonic acid group is preferable. In order to bond the amino group with wet heat, it is particularly preferable to attach a compound having an amino group to the undried yarn and then perform a wet heat treatment at the stage of producing acrylic synthetic fiber or modacrylic synthetic fiber. Examples of the compound having an amino group include sulfanilic acid, metanylic acid, and orthonylic acid, and a compound having an amino group having two or more functional groups is preferable, and examples thereof include hydroxyamine sulfate, ethylenediamine, and diaminopropylamine. Particularly preferred is a polymer compound having an amino group having two or more functional groups, and one or more of polyethyleneimine, polyallylamine, amine-modified acrylic polymer, and chitosan. The latter (Japanese Patent Application No. 7-172539) has an amino group content of 1 to 2 equivalents per unit of monomer and a polymerization degree of 7 to 2400 in a state where the polymer is embedded in the fiber. Artificial fiber containing 10% owf and 0.2 to 10 equivalents / kg of anionic functional group or a transition metal salt in which the anionic functional group is combined with 0.1 to 5 equivalents / kg of transition metal Deodorant fiber. If the content or the degree of polymerization is out of this range, there are problems in deodorizing properties, handling properties and fiber production, and the deodorizing performance is insufficient. Here, as the amino group-containing polymer, there is at least one kind of polyethyleneimine, polyacrylamine, amino-modified acrylic polymer, and the like. In order to bury the amino group-containing polymer inside the fiber, spinning is performed during wet spinning. Before drying, there is a method of impregnating in a dipping tank or the like. As the anionic functional group, a carboxyl group and / or a sulfone group is preferable, and a carboxyl group is particularly preferable. For containing a carboxyl group, for example, a carboxyl group-containing polymer such as acrylic acid that hydrolyzes acrylic fiber with alkali After copolymerization or polymer blending, and further, wet spinning, immersion in an undried state in the polymer aqueous solution, and drying. The transition metal includes copper zinc and the like, and the transition metal salt includes a copper compound (CuSO4, Cu (NO3)2Etc.), zinc compounds (ZnSO4, Zn (NO3)2Etc.) are preferred. Here, artificial fibers include synthetic fibers such as rayon such as cupra and viscose, acetate, polyester, and acrylic, and fibers include natural fibers such as silk, wool, and hemp in addition to artificial fibers. Things.
[0017]
Further, in the present invention, in addition to the above-mentioned fibers, deodorizing fibers having a main deodorizing mechanism of a chemical decomposition or physical adsorption mechanism may be used. The deodorizing fiber having a main deodorizing mechanism of chemical decomposition is not particularly limited, but for example, a fiber obtained by adding phthalocyanine and iron to the fiber, a fiber obtained by post-processing or kneading L-ascorbic acid and iron, and the like. Can be used. Further, the deodorant fiber itself may be a bulky one. As the deodorizing fiber having a main deodorizing mechanism by physical adsorption, activated carbon fiber or fiber obtained by adding ceramic powder such as aluminum silicate to the fiber by post-processing or kneading can be used.
[0018]
As described above, powdered activated carbon is preferred as the deodorant used in the present invention. The activated carbon powder used in the present invention refers to a porous powder obtained by baking a commonly used coconut shell, tar, or resin as a raw material. In particular, activated carbon fractionated to 20 to 80 mesh using coconut shell as a raw material is preferable because it has a large specific surface area and has a quick deodorizing performance, compared with ordinary pellet-shaped activated carbon (particle diameter: 4 mm).
[0019]
In the present invention, when activated carbon is used as a deodorant, the amount of activated carbon attached is from 10 to 100 g / m in view of deodorant performance and productivity.2Is preferred. 10g / m2If the amount is smaller, the deodorizing performance is low even if the structure of the dress cover is adopted, and the tobacco odor cannot be sufficiently removed. On the other hand, 100 g / m2If the amount is larger, the deodorizing performance is sufficient, but the hand becomes extremely hard and requires a very large amount of heat to fix using a hot melt agent, resulting in poor productivity, and furthermore, sewing is extremely difficult. Is not preferred. The amount of activated carbon attached is 10 to 40 g / m.2Is more preferable in terms of productivity and texture.
[0020]
In the present invention, when activated carbon powder is used as a deodorant, the breathable sheet-like material has a laminated sheet structure in which activated carbon powder is bonded with a hot melt agent between two breathable sheets. Is particularly preferable in terms of deodorizing performance and feeling.
As the hot melt agent in the present invention, a hot melt agent having a lower melting point than the air-permeable sheet to be used can be used. That is, hot melt agents such as polyethylene, vinyl acetate, nylon, polyester, and composites of two or more of these, which are commonly used for bonding bonded interlinings, can be used. Among them, vinyl acetate-based or a mixture of vinyl acetate-based resin and another resin is preferable because of its high melting point and high production efficiency. It is preferable that the amount of the hot melt agent attached is 50% to 200% by weight of the amount of the activated carbon powder used. If it is less than 50%, the adhesion becomes insufficient, the activated carbon powder is not fixed, and the activated carbon powder is liable to fall off the sheet, and the two air-permeable sheets are separated during handling such as cutting the sheet. On the other hand, if it exceeds 200%, most of the activated carbon surface will be covered with the hot melt agent, and the deodorizing performance will be impaired. From the viewpoint of texture and sewing, 100 to 170% is preferable.
[0021]
In the dress cover of the present invention, it is preferable to use a basic odor absorber together with the above-mentioned activated carbon as a deodorant, since it is difficult to adsorb ammonia, which is a basic odor, with activated carbon alone. In particular, most of the malodors such as tobacco odors generated in daily life are complex odors, and two or more of basic odor, acidic odor and neutral odor are mixed. Most of the products having the conventional deodorizing performance remove a part of the complex odor, but the present invention uses the basic odor absorbing agent together with the activated carbon to obtain the effect of both the deodorizing agents. This makes it possible to eliminate the odor of tobacco without damaging the odor.
[0022]
The basic odor adsorbent referred to in the present invention is a polyacrylic acid type, maleic acid type, polyhydric phenol type, metal acetate, manganese sulfate, ascorbic acid type or other acidic chemical deodorant, acid-impregnated activated carbon, Refers to physicochemical adsorbents such as zeolites and ceramics. In other words, the tobacco odor has a relatively large amount of basic odors such as nicotine (including modified nicotine such as pyridine and pyrrole), ammonia, and trimethylamine. , It is possible to more effectively remove the tobacco odor attached to the clothes. 0.3 g / m of basic odor deodorant2~ 5g / m2Is preferred. 0.3g / m2If it is below, even if it takes the form of a dress cover, the deodorizing performance is low and the tobacco odor is not sufficiently removed. In addition, 5 g / m2Above this, the feel becomes extremely hard even without using an adhesive, and sewing becomes extremely difficult, which is not preferable.
.
[0023]
Next, a deodorant laminated sheet for a dress cover according to the present invention and a method for producing the same will be described. The deodorant laminated sheet for a dress cover according to the present invention is a laminated sheet in which activated carbon powder is fixed between sheets by a hot melt agent. Here, the activated carbon powder only needs to be supported to such an extent that the activated carbon powder does not detach from the sheet-like material, and a part of the activated carbon powder surface is supported by being joined to the air-permeable sheet with a hot melt agent. That is, since the obtained sheet is activated carbon powder, a hot melt agent, and a gas-permeable sheet material is point-bonded by the hot melt agent, the surface of the activated carbon powder is less covered with the adhesive, and the deodorizing performance is high. It can be supported on a breathable sheet while maintaining it. In addition, since such a bonding mode is point bonding, a deodorant sheet which is flexible in terms of feeling can be obtained.
[0024]
The above-mentioned deodorant sheet for dress cover is obtained by a production method in which activated carbon powder and a hot melt agent are sprayed on a gas permeable sheet, and then another gas permeable sheet is laminated and hot-pressed to bond and integrate.
That is, a mixed powder of the activated carbon powder and the hot melt agent is prepared in advance using a commonly used powder mixer such as a homoxer or a rotary mixer. Next, the mixed powder is sprayed on a breathable sheet by a powder shake-off device used when manufacturing an adhesive interlining or the like. Further, the hot melt is softened or melted by a hot press roll after laminating the air-permeable sheets to bond and integrate them.
[0025]
Embodiment
Hereinafter, the present invention will be described using examples. In the examples, all parts are based on weight unless otherwise specified.
Further, a sensory test was performed by the following method to evaluate dress cover performance.
(1) Between 10 tatami mats (40.5m3) Hanging a gentleman's suit using wool fabric in the room,
160 cigarettes (trade name "Mild Seven" manufactured by Japan Tobacco Inc.) are burned and left for 2 hours.
(2) Take out the gentleman's suit, put on the dress cover, and 4.5 tatami mats (13.1m)3) And allowed to stand for 2 hours, and then subjected to a sensory evaluation by the following method.
{Circle around (3)} After informing six monitors of the smell of cigarettes, the gentlemen's suit and the air odor during 4.5 tatami mats were determined according to the criteria in Table 1. For comparison, the initial odor intensity of the gentleman's suit immediately after being taken out in (1), the air odor intensity between 4.5 tatami mats before the gentleman's suit was inserted, and 4.5 tatami mats without a dress cover were applied. After hanging and standing for 2 hours, the odor intensity of the gentleman's suit was determined according to the criteria in Table 1 for the odor intensity of the air during 4.5 tatami mats.
[0026]
Embodiment 1
Polyethylene terephthalate is melt-spun and drawn from the spinneret by air soccer to create a uniform long-fiber web, which is placed between an embossed roll having uniformly arranged convex portions and a lower roll having a smooth surface. Thermocompression bonded, fineness 2d, basis weight 30g / m2, A long-fiber nonwoven fabric was obtained.

The mixture was mixed by a rotary powder mixer to obtain a mixed powder of activated carbon powder and hot melt agent powder. Next, usually, using a hot roll bonding type laminating apparatus equipped with a powder dispersing apparatus used for laminating paper or cloth, the sum of the activated carbon powder and the hot melt agent powder was formed on the previously prepared long-fiber nonwoven fabric. 60g / m2And sprayed. Furthermore, the same long-fiber nonwoven fabric was overlaid and joined by a hot press roll heated to 150 ° C. to obtain a deodorant laminated sheet A.
[0028]
As shown in Table 2, the deodorizing laminated sheet A and the previously prepared long-fiber nonwoven fabric were cut into rectangles each having a size of 90 cm × 60 cm, overlapped, and a fastener was attached to one long side of the rectangle. The three sides were joined by a welder-type sewing machine to obtain a bag-like material using a deodorant laminated sheet on one side. Furthermore, a cut of 5 cm was made at the center of one short side in order to pass the hooked part of the clothes hanger, and a dress cover was formed and used for evaluation.
[0029]
Table 3 shows the sensory evaluation results of the gentlemen's suit odor intensity and Table 4 shows the air odor intensity evaluation results for 4.5 tatami mats. According to Tables 3 and 4, when the gentleman's suit with the initial odor intensity of 4.2 was hung between 4.5 tatami mats without a cover, a part of the cigarette smell attached to the gentleman's suit remained in the room. It can be seen that the odor intensity of the gentleman's suit spreads to 2.8, and the odor intensity of the air in the room rises from 0 to 1.8. In comparison, in Example 1, the odor intensity of the gentleman's suit itself was 1.8, indicating that the smell of tobacco was removed as compared to the case without the cover. On the other hand, the air odor intensity during 4.5 tatami mats is also 1.1, which indicates that the cigarette odor is prevented from being scattered from the gentleman's suit compared to the state without the cover.
[0030]
Embodiment 2
