【００３４】
本発明の水性組成物は有効量の有機溶剤を含んでいてもよいが、繊維内に十分に水性組成物を含浸させるために、また安全性の上からも揮発性の高い有機溶剤は少ないほうがよく、１０１３．２５ｈＰａ（＝１ａｔｍ）における沸点が９０℃以下の有機溶剤が好ましい。１０１３．２５ｈＰａ（＝１ａｔｍ）における沸点が９０℃以下の有機溶剤としては、メタノール、エタノール、２−プロパノールなどが挙げられる。有機溶剤の配合量としては、水性組成物中１０重量％以下、好ましくは８重量％以下、特に好ましくは５重量％以下である。なお、本発明では、後述の各香料成分は、有機溶剤として扱わないものとする。

【００４８】
殺菌剤は水性組成物中０．０１〜１０重量％、更に０．１〜５重量％、特に１〜５重量％含有されるのが好ましい。
【００４９】
また、本発明の効果を損なわない範囲でその他の成分として、柔軟剤、着色剤、糊料、ｐＨ調整剤または緩衝剤などを含んでもよい。
【００５０】
本発明の水性組成物の残部は水である。水を多く含むことによって、乾燥中に本発明の組成物が一度に揮発することなく、安全で且つ優れた効果を得ることができる。水は、重金属イオンや硬度成分を除去した水が好ましく、イオン交換水や蒸留水が好ましい。
【００５１】
また、本発明の水性組成物のｐＨ（２０℃）は３．０〜９．０、好ましくは５．０〜８．０が望ましい。
【００５２】
本発明の水性組成物は、有効成分を０．０１〜５重量％含有することが特に好ましい。０．０１重量％以上であれば、水性組成物の繊維への浸透性が良く、十分なしわ除去や異臭除去効果が発揮される。また、５重量％以下であれば、好ましい風合いが付与され、着色や輪じみ等の問題も抑えられる。
【００５３】
本発明の水性組成物の最も好ましい態様は、シリコーン化合物０．０１〜５重量％、界面活性剤０〜５重量％、沸点が９０℃以下の有機溶剤０〜５重量％、及び水８５〜９９．９重量％を含有するものである。
【００５４】
本発明の処理方法では、前記水性組成物を繊維製品に対して噴霧するが、噴霧剤を配合しない、いわゆるノンガスタイプの噴霧装置を用いるのが好ましい。噴霧装置は水性組成物を繊維製品にできるだけ広い面積に均一に噴霧できるものがよく、好ましい噴霧器具としてはトリガー式スプレイヤーまたはポンプ式ディスペンサーである。
【００５５】
使いやすさの面からスプレー１回あたりの好ましい噴霧量は０．０１〜３．０ｇ、さらに好ましくは０．０５〜２．０ｇであり、対象物から２０ｃｍ離した距離からスプレーしたときの噴霧面積が約５０ｃｍ²〜約５００ｃｍ²であるトリガー式スプレイヤーまたはポンプ式ディスペンサーを用いるのが望ましい。噴霧量が０．０１ｇ以上であると広い面積を噴霧するのが容易で、また３．０ｇ以下の場合、繊維製品への水性組成物の付着量が適正となり、乾燥時間を短縮でき、また輪ジミも生じない。
【００５６】
また、使用時において、１度の噴霧における霧滴（液滴）の総数のうち、粒子径が１０００μｍを超えるものの数を１％以下、好ましくは５００μｍを超えるものの数を１％以下、さらに好ましくは２００μｍを超えるものの数を１％以下であり、噴霧液滴の少なくとも約５０％の液滴が１００μｍ以下の粒度を有するスプレーを用いると、処理対象となる衣類等の繊維製品に対して本発明の水性組成物を確実かつ均一に付着させることができるため、効果が高く、衣類に輪ジミが残りにくい。なお、このような粒子径分布は、例えば、レーザー回折式粒度分布計（日本電子製）により測定することができる。
【００５７】
また水性組成物を噴霧する前の繊維製品は実質的に乾燥状態にあることが好ましい。水性組成物は、このような実質的に乾燥した繊維製品の重量に対して５〜２００％噴霧するのが望ましい。ここでいう「実質的に乾燥した状態」とは、手で触っても湿り気を感じない状態であり、湿度によって衣類は多少の水分を含んでいる。以下、乾燥に関する部分について詳述する。
【００５８】
水性組成物が噴霧された繊維製品は、回転槽内、例えばドラム式の回転式乾燥機内で乾燥処理を行う。前記水性組成物を噴霧された繊維製品は速やかに、具体的には６０分以内、好ましくは３０分以内に乾燥機内に入れられ、好ましくは５０〜９０℃の間で、１０〜６０分間、好ましくは１５〜４５分間、乾燥処理が行われる。
【００５９】
回転槽の回転速度は衣類の仕上がり性に影響する。一般に回転式乾燥機は、回転し始めてからしばらくすると等速円運動に達する。質点Ｐが原点Ｏを中心とする半径γの円周上を等速円運動する場合、円周上のＰにおける速度ベクトルυは、円周の接線方向であり、その大きさは
υ＝ωγ ［ω；角速度、γ；半径］
で表わされる。
【００６０】
またωには、
ω＝２π／Ｔ ［Ｔ；質点Ｐが１回転するのに要する時間］
の関係が成り立つので、以下の式が得られる。
【００６１】
υ＝２πγ／Ｔ
本発明に最適な速度υ（以下、周速度で表す）は、０．１〜１０（ｍ／ｓ）、好ましくは０．２〜６．０（ｍ／ｓ）、さらに好ましくは０．５〜４．０（ｍ／ｓ）である。この範囲において衣類が縮んだりほつれたりすることなく、充分な効果が得られる。
【００６２】
水性組成物を噴霧した繊維製品を回転させつつ乾燥することで、吊り干し等で静置したままで乾燥しても取れないシワを、ほぼ完全に除去でき、また仕上がりもふんわりとした良好な感触が得られる。
【００６３】
本発明に用いられる回転乾燥機としては、家庭用の乾燥機を用いることができる。通常、家庭用回転式乾燥機は、回転槽の回転軸が鉛直方向と直交する方向にあり、種々の設定ができるようになっているが、乾燥温度、回転数及び時間が前記範囲を逸脱しない限り、いずれのコースを用いて乾燥処理を行ってもよい。
【００６４】
本発明の処理方法では、繊維製品を水性組成物で処理した後、可撓性を有し、実質的に通気性を有する容器に収容してから、乾燥工程に供することが最も好ましい。容器は、繊維製品の乾燥機中で溶融しないポリエステル、ポリプロピレン、ナイロンなどから製造される。容器は、通気性を発現するために、網状部材、穿孔シート等により形成される。容器の大きさは、スーツなどが収容可能で、乾燥機内で回転できる程度が望ましい。また、容器の形状は、袋状（封筒状）、球型、円柱型、四角柱型、三角柱型、三角錐型等でもよいが、回転での乾燥に適した袋状、球型、円柱型が好ましい。容器は、繊維製品を出し入れする開口を有する。この開口は、繊維製品の収容後は、チャック、面ファスナー、フック、ボタン、ゴム、ひもなどの適当な手段により封止される。
【００６５】
本発明に用いられる容器は、内部に収容した繊維製品の水分蒸発速度が０分（収容直後）から１０分後の間で０．３０〜０．５０ｇ／ｍｉｎ、更に０．３５〜０．５０ｇ／ｍｉｎ、特に０．４０〜０．５０ｇ／ｍｉｎであることが好ましい。この範囲の水分蒸発速度を有することにより、過剰な水分による衣類の新たなシワの発生が防止でき、また適度な乾燥状態となるので繊維の傷みも少なくなる。この水分蒸発速度は以下の方法で測定されたものである。
〔水分蒸発速度の測定方法〕
（１）綿金巾（２００３布、谷頭商店、５０ｃｍ×５０ｃｍ）４枚を、２０℃、５０％ＲＨの条件で２４時間放置し、秤量する。この値を布重量Ｗ₀とする。
（２）布に、スプレーで片面全体に水を吹き付け、布重量を測定する。その際、水付着量の目安は、綿布５ｇとした。この値をＷ₁とする。Ｗ₀とＷ₁から、Ｗ₁−Ｗ₀により初期の水分付着量Ｗ₂が得られる。
（３）容器に綿布を収容し、家庭用回転式衣類乾燥機（松下電器産業株式会社製、ＮＨ−Ｄ４５Ａ）を用い、ヒーター強、標準、２０分コースに設定し、スタートボタンを押してから１０分経過後に停止させる。
（４）停止後、容器から綿布を取り出し、３分以内に重量を測定する。この値をＷ₃とすると、このＷ₃と布重量Ｗ₀から、Ｗ₃−Ｗ₀により残存水分量Ｗ₄が得られる。このＷ₄とＷ₂とから、以下の式により、布１枚当たりの水分蒸発速度が算出される。綿布４枚の水分蒸発速度の平均値をその容器の水分蒸発速度とする。
【００６６】
水分蒸発速度（ｇ／ｍｉｎ）＝（Ｗ₂−Ｗ₄）／１０
本発明に用いられる容器は、目付が６０〜６００ｇ／ｍ²、更に６０〜４００ｇ／ｍ²、特に１００〜２００ｇ／ｍ²であることが好ましい。糸密度が（縦６本×横６本）／ｃｍ²〜（縦５０本×横５０本）／ｃｍ²であることが好ましい。目付と糸密度は、上記の水分蒸発速度を達成できる範囲が好ましい。
【００６７】
本発明によれば、前記本発明の水性組成物を噴霧装置を備えた容器に充填した物品と、前記容器、好ましくは袋状部材との組み合わせたキットとして新しく提案することもできる。
【００６８】
本発明では、前記本発明の水性組成物を噴霧装置付き容器に充填した物品と、繊維製品を収容するための可撓性を有し実質的に通気性を有する容器、好ましくは袋状部材とからなる、回転式乾燥機を用いて繊維製品の処理に用いられるキットとすることにより、利用者の利便性を向上できる。
【００６９】
本発明の処理方法は、特に綿、麻、ウールなどからなる衣類に対して高い効果を示し、例えばスーツ、スラックス、ジャケット等の衣類に噴霧して使用するのが望ましい。
【００７０】
【発明の効果】

BACKGROUND OF THE INVENTION
The present invention relates to a method for treating a textile product for restoring the texture of the textile product, and in particular for the purpose of removing wrinkles and odors, and more particularly to a method for treating clothing, an aqueous composition therefor, and a kit therefor.

Generally, dry cleaning clothes such as suits are difficult to wash with water at home, and methods for removing wrinkles generally include ironing and steam press. As a means of stretching the wrinkle of clothes without using them, after spraying a composition combining water with a specific water-soluble solvent such as hexylene glycol and isoprene glycol in JP-A-10-25660, A method of removing wrinkles by simply leaving it alone is disclosed. However, although this method can remove light wrinkles on clothes, it is difficult to completely remove deep wrinkles. In addition, Japanese National Patent Publication No. 10-508911, WO99 / 55952, WO99 / 55953, and Japanese Patent Application Laid-Open No. 1-6174 show compositions and methods for wrinkle removal of fabrics.

Then, it was dried with a household rotary clothes dryer (Matsushita Electric Industrial Co., Ltd., NH-D45A) for 20 minutes. After completion of drying, the sample was allowed to stand at room temperature for 1 hour, and then the wrinkle removal, texture and smell of the test cloth were determined.
[0075]
Further, as described above, each sprayed sprayed test cloth was placed in a constant temperature dryer (Yamato Chemical Co., Ltd., DN810) constant temperature at 65 ° C. for 20 minutes and dried. After removing from the dryer and allowing to stand at room temperature for 1 hour, the degree of wrinkle removal, texture, and smell of the test cloth were determined.
[0076]
Evaluation was made by scoring the cloth treated with a dryer by five panelists and the cloth (control) before the treatment according to the following criteria, and the average value was obtained as an evaluation score. The results are shown in Tables 1-3.

Example 2
An aqueous composition having the composition shown in Table 5 was prepared, and the texture, wrinkle removing property and odor removing property of the clothing were evaluated in the same manner as in Example 1. However, the test cloth was placed in a net or bag shown in Table 6 and placed in a dryer. Tables 7 and 8 show the combinations of the aqueous composition and the net and the evaluation results. In addition, instead of the model tobacco odor, the odor was evaluated as a model sweat odor on each piece of fabric (10 cm × 10 cm) with 0.0002% by weight of isovaleric acid, 0.0006% by weight of acetic acid, 3-methyl-2 A solution obtained by spraying 0.6 g of an ethanol solution composed of 0.0002% by weight of hexanoic acid and 99.99990% by weight of ethanol was used.
