Description
本発明は、繊維製品への易洗浄性の付与方法、及び繊維製品用易洗浄性付与剤に関する。 The present invention relates to a method for imparting easy-to-cleanability to textile products and an easy-to-cleaning agent for textile products.
従来から、繊維に汚れが付着することを防止したり、付着した汚れを落ちやすくしたりするための防汚・易洗浄化処理方法が種々提案されている。
特許文献１では、繊維及び生地に平均粒子径が１μｍに満たない水不溶性粉体、例えば二酸化珪素、酸化アルミニウムなどの水不溶性粉体を含有させた処理液で処理することで汚れの付着抑制と汚れの離脱性能を促進させようとする提案がなされている。
また、特許文献２には、洗濯耐久性のある内層と外層の複合被膜層を持つ防汚性と着用快適性を有する繊維布帛とその製造方法が開示されている。
さらに特許文献３には、繊維材料に対して、多糖類を付着させる工程と、繊維材料に対して、変性オルガノシリケート微粒子を付着させる工程とを含む、防汚加工繊維の製造方法が開示されている。
Conventionally, various antifouling / easy-cleaning treatment methods have been proposed for preventing dirt from adhering to fibers and making it easier to remove the adhering dirt.
In Patent Document 1, the adhesion of stains is suppressed by treating the fibers and the fabric with a water-insoluble powder having an average particle size of less than 1 μm, for example, a treatment liquid containing a water-insoluble powder such as silicon dioxide or aluminum oxide. Proposals have been made to promote dirt removal performance.
Further, Patent Document 2 discloses a fiber fabric having a composite coating layer of an inner layer and an outer layer having washing durability and having antifouling property and wearing comfort, and a method for producing the same.
Further, Patent Document 3 discloses a method for producing an antifouling processed fiber, which comprises a step of adhering a polysaccharide to a fiber material and a step of adhering modified organosilicate fine particles to the fiber material. There is.
洗浄によって落としきれない汚れは、微生物による資化によって悪臭を発生させる原因となることや、汚れ成分同士が繊維と重合して黄ばみの原因となることが知られている。そのため、一般的な衣類をはじめとする繊維製品に対し、予め簡易な処理を施しておくことで、繊維製品に易洗浄性を付与する、簡便な方法が望まれている。
本発明は、繊維製品に、より優れた易洗浄性を付与する方法を提供する。
It is known that stains that cannot be completely removed by washing cause a foul odor due to assimilation by microorganisms, and that stain components polymerize with fibers to cause yellowing. Therefore, there is a demand for a simple method for imparting easy cleaning property to textile products by subjecting textile products such as general clothing to simple treatment in advance.
The present invention provides a method for imparting better detergency to a textile product.

洗浄率（％）＝（付与した汚れ量−洗浄後に残った汚れ量）／付与した汚れ量×100
<Calculation of cleaning rate>
One piece of cloth after washing is cut into 64 parts, placed in a vial with 2 ml of deuterated chloroform (Wako Pure Chemical Industries, Ltd.), extracted for 15 minutes with an ultrasonic cleaner, and then 1 ml of extract and 0.05 vol% of trimethylsilane. 1 ml of deuterated chloroform (Wako Pure Chemical Industries, Ltd.) was mixed, and 0.7 ml of the obtained mixed solution was subjected to 1 H-NMR measurement (NMR-MR4000, Agent). From the peak area of 5.3 ppm corresponding to the hydrogen in the double bond portion of oleic acid in the obtained NMR spectrum, the amount of oleic acid remaining after washing, that is, the amount of stains remaining after washing is determined based on the calibration curve. Calculated. The cleaning rate (oleic acid degreasing rate from cloth) was calculated by the following formula. The results are shown in Table 2.
Cleaning rate (%) = (Amount of stains applied-Amount of stains remaining after cleaning) / Amount of stains applied x 100
