DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aqueous composition for removing wrinkles from textiles such as shirts, suits, pants and skirts such as shirts. More specifically, the present invention relates to an aqueous composition for removing wrinkles of textiles, which can remove wrinkles formed on clothing by simply spraying on wrinkles of clothes without ironing or pressing, after spraying on wrinkles of clothes. is there.

2. Description of the Related Art Clothing such as suits and trousers often wrinkles during wearing or preservation. Especially in summer, there are many occasions when carrying an outerwear in a hand, so that wrinkles are easily formed and the appearance is impaired. Many. Normally, ironing or steam press is used as a means of extending wrinkles formed on clothing, but such a method requires a power source and a heat source and cannot be used easily anywhere. It has such a drawback. As a means to stretch wrinkles of clothing without using ironing or steam press,
Japanese Unexamined Patent Publication (Kokai) No. 64-6174 discloses a method of spraying a composition comprising a combination of an alcohol selected from the group consisting of ethyl alcohol, propyl alcohol and isopropyl alcohol, glycerin, a nonionic surfactant and water, followed by drying. A method for removing wrinkles is disclosed. This method is effective for clothing that does not shrink due to water such as cotton or polyester cloth, but it is effective for clothing that tends to shrink when it comes in contact with water, especially clothing such as wool, rayon, cupra, etc. By using the leverage technique, wrinkles of clothes can be removed, but not only shrinkage occurs due to the effect of water in the composition, but also the alcohol contained in the composition further accelerates shrinkage, causing the clothing to lose its shape. It has been found that it has a drawback of causing such a phenomenon.

[0002]

SUMMARY OF THE INVENTION The present invention not only exhibits a good wrinkle-removing effect on garments such as wool, rayon and cupra which are liable to be shrunk when they are wetted with water. An object of the present invention is to provide an aqueous composition for removing wrinkles of textiles, in which the shrinkage of clothing caused by spraying the composition is suppressed as much as possible and the shape of clothing is hardly lost.

SUMMARY OF THE INVENTION The present invention provides an aqueous composition containing a specific water-soluble solvent, which not only exhibits a good wrinkling effect on clothing such as wool, rayon or cupra, This is based on the finding that it has the effect of suppressing the shrinkage of clothing that occurs when spraying. That is, the present invention provides the following general formulas (1) to (4)
And a water-soluble solvent selected from the group of water-soluble solvents represented by the formula: and water.

It is a synthetic higher alcohol having a carbon number of 12 to 13 as a main component and containing an α-methyl branch (linear ratio: 80%) (manufactured by Mitsubishi Chemical Corporation). The effect of suppressing the shrinkage of the clothing and the evaluation of the wrinkles of the clothing were evaluated by the following methods. [Evaluation Test of Clothing Shrinkage Inhibition Effect] 1) Test Cloth A commercially available wool (tropical) or rayon (taffeta) cut into a size of 50 cm in the vertical direction and 15 cm in the horizontal direction was used as the test cloth. 2) Evaluation test Marks are made at intervals of 45 cm in the longitudinal direction of the test cloth. This test cloth is adjusted to 25 ° C. in advance and immersed in the aqueous composition for removing wrinkles for 10 minutes. Next, the sample is dehydrated using a dehydrator of a two-tub washing machine for 30 seconds to remove excess sample liquid.
After drying overnight in the room, measure the length between the pre-marked marks. This length is defined as Lcm. The contraction rate is calculated by the following equation. Shrinkage (%) = [(45−L) / 45] × 100

3) Judgment Criteria The shrinkage rate of various aqueous compositions for removing wrinkles was compared with the shrinkage rate when purified water was used, and the effect of suppressing shrinkage of clothes was judged based on the following criteria. ：: better than the shrinkage rate when using purified water (does not shrink) △: equivalent to the case using purified water ×: worse than the shrinkage rate when using purified water (shrinks) [Evaluation test for clothing wrinkles 1) Test cloth As the test cloth, commercially available wool (surge) is 20 × 5 cm.
Was used. 2) Evaluation test Fold the test cloth five times at right angles to the long direction. A load of 5 kg is applied as it is and left at 20 ° C. overnight. Next, the load is removed, one end of the test cloth is fixed with a clip, and the test cloth is suspended vertically. After a lapse of 30 minutes, the length from the upper end to the lower end of the test cloth is measured, and the value is defined as the value (A). The prepared aqueous composition for removing wrinkles was pumped from a distance of 15 cm to a test cloth at 40 g / m ² using a pump-type dispenser.
Spray the amount of One hour later, the length from the upper end to the lower end of the test cloth is measured, and the value is defined as a value (B). On the other hand, the length of the test cloth in a completely stretched state is measured, and the value is defined as a value (C). The wrinkle recovery rate is calculated by the following equation. Wrinkle recovery rate (%) = [(BA) / (CA)] × 100 3) Criteria ○: Wrinkle recovery rate of 90% or more ×: Wrinkle recovery rate of less than 90% The results are summarized in Table-1. Show.
