DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cleaning dry products by washing with water.

[0002]

2. Description of the Related Art Generally, in the cleaning industry, washing can be roughly classified into dry cleaning and water washing. Of these, dry cleaning is usually performed on fiber products such as wool, silk, rayon and the like which are likely to shrink when washed with water. In dry cleaning, solvents such as 1,1,1-trichloroethane, perchlorethylene, 1,1,2-trichloro-1,2,2-trifluoroethane, and petroleum are used. But,
In recent years, the use of chlorofluorocarbon-based and halogen-based solvents has become difficult, and the use of petroleum-based solvents has been increasing due to pollution problems such as destruction of the ozone layer, pollution of groundwater, and problems of carcinogens. However, there is a danger problem in petroleum solvents. Also, in terms of detergency, a decrease in detergency is inevitable as compared with fluorocarbon and halogen solvents. Therefore, at present, almost no expectation can be made on the detergency of water-soluble stains such as protein stains and sweat. As described above, the conventional dry cleaning does not remove water-soluble dirt, and the cleaning performance of the object to be cleaned is insufficient.

[0003]

The object of the present invention is to break the conventional wisdom, to prevent the shrinkage by washing with water, to prevent the dye from being transferred to other articles to be washed, and to be effective as a cleaning agent for washing with water. An object of the present invention is to provide an anti-shrinkage agent and a method for cleaning a dry product by rinsing with water.

[0004]

According to the present invention , an object to be washed is washed using a water-repellent silicone emulsion and a detergent.
Then use a water-repellent silicone emulsion.
Rinsing process and silicon with water repellency
The present invention relates to a method for cleaning a dry product by washing with water, which is a finishing treatment using a system emulsion . In the present invention, it has been found that by using the above-described water-repellent silicone emulsion, the water-repellent silicon emulsion has the property of adsorbing or forming a film on the fiber surface and has water repellency, thereby preventing shrinkage.

The water-repellent silicone emulsion of the present invention includes, for example, dimethylpolysiloxane oil,
Examples include amino-modified silicone oil and hydrogen-modified polysiloxane, and amino-modified silicone oil is particularly preferable.

Although a fluorine-based water repellent and a zirconium-based water-repellent have a sufficient shrinkage-preventing effect, when they are used as finishing agents themselves, they become hard in terms of texture, so it is necessary to separate the shrinkage-preventing agent from the finishing agent. There is inconvenience. In addition, it has been found that a high concentration of an emulsion of animal and plant and mineral oil or a modified product thereof has an effect of preventing shrinkage. For example, a softer such as distearyl dimethyl ammonium chloride has a shrinkage-preventing effect, but in this case, it is necessary to spray or devise a chemical agent on the fiber in order to improve the adsorption performance on the fiber. Become. When such a substance is used as an anti-shrinkage agent, the color is transferred to other fibers. Therefore, it is necessary to consider temperature control as well as pH control and transfer prevention.

The present invention also relates to a method for cleaning a dry product by washing with water using the water-repellent silicone emulsion. If the water washing process is classified by process, the washing process,
Rinsing process and finishing process can be roughly classified. The most important step for preventing shrinkage is the washing step, and it is desirable to add 1 to 5% by volume of the water-repellent silicone emulsion of the present invention to the amount of water. The temperature is preferably from room temperature to 40 ° C., particularly preferably from 35 to 40 ° C. In addition, it is desirable not to use a detergent having a strong penetration force. In the rinsing step, 0.5 to 2% by volume of water is added.
Also in the finishing step, a sufficient finish can be obtained by using a concentration of about 0.5 to 2% by volume with respect to water.
The rinsing step may be omitted from the above steps.

In the present invention, a softer such as, for example, distearyldimethylammonium chloride can be used if necessary. In the present invention, for example, wool, silk,
Washing new synthetic fiber, polyester, nylon, rayon, etc.
It can be washed, has excellent wrinkle growth, and has an excellent effect that almost no ironing is required.

[0009]

The present invention will be described in more detail with reference to the following examples.

EXAMPLE 1 Hot water at 35 ° C. was prepared in a washer at a medium water level, and an amino-modified silicone oil emulsion (Star Jewel Wet) was put therein in an amount of 2 to 2.3% by volume based on water. Put the laundry and detergent, turn the machine for 10 to 15 minutes, drain without draining. Fill the washer with water at medium water level, add 1 to 1.5% by volume of Star Jewel Wet, turn for 2 to 3 minutes, and drain without squeezing. Fill the washer with water at a medium water level, add 1 to 1.5% by volume of Star Jewel Wet, turn for 2 to 3 minutes, and squeeze for 1 minute with mild dehydration. Semi-dry with a hanger up, and if it is semi-dry, finish with a tumbler and a box.

EXAMPLE 2 Hot water at 35 ° C. was prepared in a washer at a medium water level, and a mixed emulsion containing 95% by weight of star jewel wet and 5% by weight of distearyl dimethyl ammonium chloride emulsion was added to water by 2 parts. Add ~ 2.3% by volume. Put the laundry and detergent, turn the machine for 10 to 15 minutes, drain without draining. Water is poured into the washer at a middle water level, the mixed emulsion is added in an amount of 1 to 1.5% by volume, and the mixture is turned for 2 to 3 minutes and drained without squeezing. Water is poured into a washer at a middle water level, and the mixed emulsion is added in an amount of 1 to 1.5% by volume, turned for 2 to 3 minutes, and squeezed by weak dehydration for 1 minute. Semi-dry with a hanger up, and if it is semi-dry, finish with a tumbler and a box.

[0012]

According to the present invention, by using a shrinkage preventive agent, it is possible to wet-wash fibers, such as wool, silk and rayon, which are likely to cause shrinkage, which are mainly subjected to dry cleaning. Thereby,
It is very useful because it can remove oil stains, protein stains, sweat, and fatty acid stains.
