Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is directed to a method and apparatus for cleaning carpets, sofas, etc., which are ideal for cleaning textile products and items with long raised structures such as carpets, sofas, and curtains. and related to aerosol products.

0002

BACKGROUND OF THE INVENTION Conventionally, carpets have been cleaned by using steam, by spraying shampoo diluted with water, or by spraying powder.

[0003] Aerosol type cleaning agents are used to clean glass windows and furniture. For example, as shown in JP-A No. 62-39699, it contains an anhydrous volatile solvent and a surfactant, and uses carbon dioxide or nitrogen gas as a propellant.

0004

[Problems to be Solved by the Invention] Among the conventional methods, the method using steam (for example, Japanese Patent Application Laid-Open No. 61-29324) causes large shrinkage depending on the material of the carpet, and a high cleaning effect cannot be expected. Can not. Also, like the shampoo method, a large amount of water is used, so not only does it take a long time to dry, but insufficient drying can not only cause recontamination, but also shrinkage and corrosion of the carpet, backing, and damage to the flooring. It becomes a problem. In addition, the method using powder does not remove stains easily due to the low moisture content, which causes problems as a large amount of powder residue remains on the carpet.

[0005]Using an aerosol type cleaning agent that does not use water has advantages over the steam and shampoo methods described above, but in the case of materials with long pile structures such as carpets, it is difficult to use deep piles. Not only is it not very effective in removing dirt from the area, but it also has the drawback of increasing cleaning costs because a large amount is used.

[0006] In view of the above, the present invention does not cause corrosion such as shrinkage or backing or damage to the flooring, completes the work in a short time, leaves no oily secondary residue, and is easy to clean. The purpose of this study is to clarify cleaning methods and equipment for carpets, sofas, etc. that have excellent power and long-lasting cleaning effects, as well as aerosol products.

[0007]

[Means for Solving the Problems] The above problems of the present invention are as follows:
Octafluorocyclobutane, dimethyl ether, LPG
After spraying a cleaning solution containing liquefied gases such as , CFCs, NO2, or compressed gases such as N2 on the surfaces of carpets, sofas, etc., buffering generates gas bubbles. A method for cleaning carpets, sofas, etc., which is capable of cleaning carpets, sofas, etc. from the deep part to the surface by moving dirt substances present in the deep parts of the carpets, sofas, etc. toward the surface of the carpets, sofas, etc.; has
At least liquefied gas such as octafluorocyclobutane, dimethyl ether, LPG, Freon, NO2 or N2
A carpet characterized in that it is equipped with a cleaning agent tank containing a cleaning agent solution in which a compressed gas such as the like is dissolved, and a buffering device that bubbles the gas dissolved in the cleaning agent solution, Cleaning equipment for sofas, etc., or ■Equipped with an injection unit, which can be used to clean liquefied gases such as octafluorocyclobutane, dimethyl ether, LPG, chlorofluorocarbons, NO2, or N2.
, liquefied gas such as octafluorocyclobutane, dimethyl ether, LPG, Freon, NO2 or N2 in an amount that can cause gas bubbles by buffering after injection. , an aerosol product characterized by containing a compressed gas such as carbon dioxide.

[0008]

[Operation] When cleaning deep dirt on carpets, sofas, curtains, etc. (hereinafter referred to as carpets) using gas, gas is generated through a chemical reaction with the dirt, and the buffering effect of pads, etc. further increases the amount of gas. Vaporization is accelerated and the vaporized gas removes dirt from carpet fibers, disperses it, and emulsifies it with special solvents (surfactants). Ions are added to the dirt and fibers to utilize ion repulsion to prevent dirt from re-adhering. The vaporized gas moves the dirt, which has been prevented from re-deposition due to the above-mentioned ion repulsion, to the carpet surface side. The moved dirt is absorbed by a porous pad or the like. The gas vaporization is further promoted by the friction caused by the porous pad, etc., and dirt is further removed.

[0009] In addition, if the tank capacity is 100ml or more,
If the amount is about ml or less, shake the tank before use, omit buffering with a pad, etc., and wipe it off with a thick cloth.

Furthermore, the contents of the aerosol product of the present invention are as follows:
It is preferable to contain carbon dioxide gas so that the pH is about 6 to 8. A compound that achieves this pH value may be used instead of carbon dioxide gas.

[0011]

EXAMPLES Next, examples of the present invention will be described in detail.

[0012] The cleaning agent used in the present invention is prepared from a liquid or powdered detergent, water, gas, and an appropriately used polishing agent. Various water-soluble detergents can be used.

The liquefied or compressed gas used in the present invention is lighter than air when vaporized, and examples include liquefied gases such as octafluorocyclobutane, dimethyl ether, LPG, fluorocarbons, and NO2, or compressed gases such as N2. . The amount of detergent (
20 parts by weight or more per 100 parts by weight (preferably a solvent),
In particular, it is preferably used in an amount of 30 parts by weight or more.

[0014] The cleaning agent prepared as above is applied to furniture and
Furniture has been removed, and a vacuum cleaner is used to evenly spread dust and dirt onto the surface of the carpet. Spraying is carried out by means of an aerosol product according to the invention, the cleaning agent being delivered in the form of a mist to the deep parts of the carpet.

[0015] After the spraying of the cleaning agent is completed, the carpet surface is buffered. Buffering is performed by rotating or rotating a rotating pad or various brushes on the surface of the carpet, which promotes the permeation of the cleaning agent and the formation of gas bubbles. Promoting the permeation of the cleaning agent involves supplying the cleaning agent deep into the nap tissue of the carpet, and promoting the formation of gas bubbles produces the following effects. Gas dissolved in the cleaning agent becomes minute bubbles due to the heat generated by friction between the carpet material and the rotating or rotating brush.

[0016] Cleaning dirt from the deep part of the carpet with gas generates gas through a chemical reaction with the dirt, and the buffering action of the pad or brush further promotes the vaporization of the gas, and the vaporized gas is absorbed into the carpet fibers. It removes dirt from the surface, disperses it, and emulsifies it with special solvents (surfactants). It uses ion repulsion to prevent dirt from re-adhering, so it adds ions to dirt and fibers. The vaporized gas moves the dirt, which has been prevented from re-deposition due to the ion repulsion, to the carpet surface side. The moved dirt is absorbed by a porous pad or the like. The gas vaporization is further promoted by the friction caused by the porous pad, etc., and dirt is further removed.

Brushing can also be carried out with a nap brush or a household appliance vacuum cleaner (preferably one with a rotating brush).

When the buffering is completed, the carpet surface is wiped with a wiping cloth (terry cloth), brushed again with a nap brush, etc., and the entire work is completed after drying.

As described above, in the present invention, gas bubbles play an extremely important role in the cleaning effect. Conventional aerosol cleaning methods also use carbon dioxide or nitrogen gas, but in the case of aerosol cleaning, liquefied or compressed gas is simply used as a propellant, and the detergent solution is jetted out in the form of foam from a nozzle. It only has the function of cleaning, and is not directly involved in the cleaning action. On the other hand, in the present invention, it is not preferable that the gas be in the form of visible bubbles when it exits from the nozzle. That is, the cleaning action is achieved by the gas dissolved in the detergent solution changing into visible minute bubbles through buffering in the subsequent process. If the detergent is supplied in the form of a foam from the beginning, as with conventional aerosol cleaning agents, it will be difficult for the detergent to reach deep into the carpet, and it will only clean the upper part of the raised tissue, which will significantly reduce the cleaning effect. Become. According to the present invention, since the cleaning agent solution that has not reached the foam state is sprayed onto the carpet, it easily penetrates deep into the carpet's raised tissue, and the subsequent buffering prevents gas from becoming bubbles. As a result, dirt substances are transferred to the upper surface of the carpet while adhering to the surface of the microscopic gas bubbles, resulting in a significantly better cleaning effect.

[0020]

[Effects of the Invention] According to the method of cleaning carpets, sofas, etc., the device thereof, and the aerosol product of the present invention, it is possible to remove dirt from deep parts of carpets etc. by the action of gas, and only a small amount of water is used. Because of this, all operations including drying can be done in a short time, which solves the above-mentioned problems. Also, the solvent (surfactant) does not leave any oily secondary residues.
