DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for washing textile products using plum vinegar and a washing aid.

[0002]

2. Description of the Related Art Textile products, especially clothing, are subject to dirt and the like when worn daily, and are cleaned by a trader in addition to washing at home for the purpose of maintaining a clean feeling and prolonging the life. ing. Commercial cleaning mainly includes land cleaning in which water and detergent are used in the same manner as home laundry, and dry cleaning in which a solvent such as parkylene is used instead of water. There are many factors that must be considered in these cleanings. For example,
It is necessary to consider not only the type and property of the stain, the property of the laundry, but also the amount of detergent, the number of times of washing (rinsing), the washing time, and the like. most,
Some of these elements cannot be said to be such.For example, increasing the washing time does not necessarily increase the cleaning effect in proportion to it. Or replace the white ones with dark ones. The use of a large amount of detergent does not mean that the detergency increases, and it is desirable to wash the detergent with a minimum necessary amount. When cleaning, for example, when soap is used as a detergent, the number of times of soap washing is also a problem. Or adhere again. Therefore, usually, in order to increase the brightness, gloss, etc. of the fabric, it is necessary to wash the soap a number of times, and in order to not leave enough detergent and dirt on the fabric, It is also necessary to increase the number of subsequent water washing (rinsing).

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to improve the detergency, reduce the amount of detergent used, reduce the number of times of washing, and favorably assist the washing when washing textiles. The purpose is to provide a technology that can do this. The above and other objects and novel features of the present invention will become apparent from the description of the present specification and the accompanying drawings.

DISCLOSURE OF THE INVENTION The present invention relates to a method for washing a textile by dry cleaning with a detergent and water, or dry cleaning with a solvent instead of the water. The present invention relates to a method for washing textiles, characterized by adding a washing aid containing ume vinegar as an active ingredient to the washing solution of the above. Further, the present invention relates to a laundry aid containing plum vinegar as an active ingredient.

[0005] The plum vinegar used in the present invention is obtained by salting plum meat, and is collected as salted and squeezed juice of plum meat. In addition to enjoying its flowers and fragrance,
Various uses are made as processed products. Besides plum vinegar,
For example, dried plums, plum wine, umebishio (plum soy sauce), added sugar, plum plum, and the like. Even if it is made of the same composition based on ume fruits, plum wine or the like is not preferable because the white component emerges after blotting. Although it belongs to the same vinegar, brewed vinegar or synthetic vinegar containing acetic acid produced by brewing as a main component is not preferable because the stain removal effect is insufficient or acetic acid smell is imparted to clothing and the like. Acetic acid is industrially obtained by oxidation of acetaldehyde or the like, but can also be obtained by a fermentation method. For example, rice vinegar is steamed rice and rice koji or saccharifying enzyme and water put in a tank, heated and stirred to saccharify, directly or filtered, yeast is added and fermented with alcohol, and further alcohol is added. It is obtained by adjusting the concentration to a constant level, adding vinegar to the mixture for acetylation, ripening and filtering. Kasu vinegar, malt vinegar, wine vinegar and the like can be obtained in a similar manner. Plum vinegar can be diluted with water or the like before use.

The ume vinegar used in the present invention improves the detergency of the detergent in both land cleaning with water and a detergent and dry cleaning in which a solvent such as parkrene is used instead of water. The amount of use can be reduced, the number of times of washing can be reduced, and the washing can be suitably assisted. When washing is performed by adding the ume vinegar to a detergent, etc., the use of detergent can be reduced by about 30%, and even with a large number of washings, the washing liquid is not turbid, the transparency is maintained, and it is usually necessary to perform the washing many times. Some washing with water is less. Furthermore, by adding ume vinegar to the cleaning solution, the discoloration (discoloration) of textile products
Can also be prevented.

[0007] The detergent (cleaning agent) used in the present invention includes:
A powder or liquid detergent containing soap or a surfactant (surfactant) can be used. As the surfactant, an anionic surfactant, a nonionic surfactant, a cationic surfactant, and an amphoteric surfactant can be used. Various additives such as a builder, a condensed phosphate, a fluorescent dye, and an enzyme can be added to the detergent. It is often used in combination with plum vinegar. It does not damage the clothing fabric, has a high removal effect, has no discoloration (color loss), maintains gloss, is inexpensive, and has no streak. Detergent). The detergent is, for example, alkylbenzene sulfonate, condensed phosphate, organic builder, pine pine stabilizer (foaming agent)
There is what mixes.

The textile product to which the present invention is applied is typically clothing, but is not limited thereto, and may be applied to tablecloths, women's scarves, etc. used in restaurants and the like. ADVANTAGE OF THE INVENTION According to this invention, although it shows a remarkable effect in fiber products in general, especially in a color thing, there is no discoloration.
Further, in washing white goods, since the turbidity of the washing liquid is reduced, it is possible to produce laundry having high whiteness. Since the detergency is improved, the type of the material is not so limited, and even a silk fabric that easily damages the fabric can be washed well. Depending on the concentration of commercially available laundry aids,
For example, there is no color loss at 60% density, but color loss may occur at 40% density.
It can be performed without being particularly affected by the concentration of the plum vinegar.

The washing operation of white goods in wet washing using water (laundry and wet cleaning) includes, for example,
It is performed by pre-washing, main washing, bleaching, rinsing, acid bath, bluing and gluing. In the washing of colored products, bleaching, rinsing,
Fluorescent whitening, blue tinting, etc. are not performed. In the present invention, in the laundry, the detergency is improved, and the detergent (soap,
Synthetic detergents) can be reduced, the number of times of water washing can be reduced, and the washing can be suitably assisted. The present invention is also applicable to dry cleaning (dry cleaning) using volatile organic solvents (preferably petroleum solvents and fluorine solvents) in addition to landries. Also in the dry cleaning, the washing power can be improved, the number of times of washing can be reduced, and the washing can be favorably assisted. As an example of the dry cleaning process, after dusting, pre-spotting (pre-spotting) [brushing with a pre-spotting liquid such as benzene soap] is performed.
Put the item in the washer containing the solvent and clean it. After several cleanings, the solvent in the washer becomes contaminated. The solvent is passed through a pressure filter by a pump to remove solids and circulate. In this case, use of dirty liquid causes reverse contamination of the laundry.
As described above, in the normal case, the liquid gradually becomes dirty, and in particular, in the washing of colored articles, the liquid becomes darker and the filter pressure also increases. Maintains properties and prolongs filter life. Due to this, in the present invention, good gloss washing can be realized.
