Description

【0001】
【発明の属する技術分野】
本発明は、おしゃれ着用洗浄剤組成物、及びおしゃれ着の洗浄方法に関する。
【0002】
【従来の技術】
おしゃれ着の洗浄における所有者の要求は多岐にわたり高く、洗浄力は元より、洗浄操作による被洗浄物の型崩れ、色合い、風合い等の変化がないこと、洗浄後の匂いといった点の要求が高い。
【0003】
これらの要求に応えるために、洗濯機においては、低攪拌力のおしゃれ着用洗濯コースが開発され、洗濯補助具として、洗濯ネットが開発されている。また、つけこみ洗いや、押し洗いといった手洗いが行われている。このように、被洗浄物の型崩れを起こしにくい低機械力の洗濯条件で洗浄力を向上させることが課題となっている。
【0004】
洗浄処理後の脱水、乾燥方法によっても、被洗浄物の型崩れ(特にしわ、縮み)が発生するため、取り扱いに注意を必要とする。また、脱水を行わずに陰干しによる乾燥が型崩れ防止には有効であるが、乾燥までに長時間を要するために、残留する水道水中の塩素イオンの増加に伴う被洗浄物の褪色の問題や、洗浄が不充分であれば匂いの問題があった。
【0005】
おしゃれ着の洗浄に用いる水は、風呂の残り湯や井戸水を用いることは極めて稀であり、一般には水道水を用いる。水道水には衛生面から次亜塩素酸イオンが使用されており、水道水の管理法令では利用者末端で有効塩素が0.1ppm以上残留することとされている。この残留塩素により、着色した被洗浄物の褪色が問題となっている。
【0006】
これらの問題に対して洗浄剤組成物としては、特定のアミノ変性シリコーンアミドを用いた衣類の縮み防止性に優れた洗浄剤(例えば、特許文献1、2、3参照)、特定の非イオン性界面活性剤の組合せとアルカノールアミンを含有する褪色防止性に優れた洗浄剤(例えば、特許文献4参照)、非イオン性界面活性剤及び陽イオン性界面活性剤を含有する洗浄剤による縮み及びしわを防止した洗浄方法(例えば、特許文献5参照)、非イオン性界面活性剤及び/又は陰イオン性界面活性剤と繊維保護剤で洗浄した後にシリコーンを含有する水性仕上げ剤で処理する型崩れ、しわ、縮みを防止した洗浄方法(例えば、特許文献6参照)等が知られている。これらの技術は部分的には使用者の要求を満たすが、課題として挙げる全ての問題を解決するわけではない。また、これらの技術を組み合わせても使用者の要求を十分に満足させることはできない。

BACKGROUND OF THE INVENTION
The present invention relates to a fashionable cleaning composition and a fashionable cleaning method.
[0002]
[Prior art]
Owners' demands for cleaning fashionable clothes are diverse, and the cleaning power is high, as well as high demands for the object to be cleaned, no change in shape, color, texture, etc., and smell after cleaning. .
[0003]
In order to meet these demands, in a washing machine, a fashionable washing course with low stirring force has been developed, and a laundry net has been developed as a washing aid. In addition, hand-washing such as soaking and pressing is performed. As described above, it has been a problem to improve the cleaning power under the low mechanical force washing condition in which the object to be cleaned is not easily deformed.
[0004]
Even after dehydration and drying methods after the cleaning process, the object to be cleaned loses its shape (especially wrinkles and shrinkage), so handling is necessary. In addition, drying by shade drying without dehydration is effective in preventing the loss of shape, but since it takes a long time to dry, the problem of fading of the object to be washed due to the increase in residual chlorine ions in tap water and If the cleaning was insufficient, there was an odor problem.
[0005]
As for the water used for washing the fashionable clothes, it is extremely rare to use the remaining hot water of the bath or the well water, and tap water is generally used. Hypochlorite ions are used for tap water from the viewpoint of hygiene, and the tap water management law states that effective chlorine remains at 0.1 ppm or more at the end of the user. The residual chlorine causes a problem of fading of the colored object to be cleaned.
[0006]
As a cleaning composition for these problems, a cleaning agent having a specific amino-modified silicone amide and having excellent anti-shrinkage of clothes (for example, see Patent Documents 1, 2, and 3), a specific nonionic property Shrinkage and wrinkles due to a combination of a surfactant and an alkanolamine-containing detergent having excellent anti-fading properties (see, for example, Patent Document 4), a detergent containing a nonionic surfactant and a cationic surfactant Cleaning method (for example, see Patent Document 5), washing with a nonionic surfactant and / or an anionic surfactant and a fiber protective agent, and then treating with an aqueous finish containing silicone, A cleaning method that prevents wrinkles and shrinkage (for example, see Patent Document 6) is known. Although these technologies partially meet the needs of users, they do not solve all the problems listed. Further, even if these techniques are combined, the user's requirements cannot be satisfied sufficiently.
