Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning cloth which can wipe off dust so as not to be scattered in the air.

[0002]

2. Description of the Related Art Conventionally, moisture, oil or resin has been previously applied to a flexible base cloth such as woven cloth or non-woven cloth, and the wiped dust is adhered to the above water or oil so that the dust is left in the air. Polishing cloths that have been processed so as not to scatter are known. If a polishing cloth moistened with water is left in the open air for a long time, the moisture evaporates and the effect of attaching dust disappears.
At present, it is not applied to anything other than single-use disposable items such as sealed hand towels, so it is impregnated with oil or resin for industrial purposes such as pre-cleaning painted surfaces of automobiles. Applied polishing cloth.

As a polishing cloth which has been conventionally used on an industrial scale, an adhesive having a resin component is applied to the surface of a base fabric (Japanese Utility Model Publication No. 54-172574), and long-chain hydrocarbon as a resin component. The base fabric is impregnated with a polymer compound consisting of the above, a modified natural resin as a fat and oil, and a fat wax as an additive (Japanese Patent Publication No. 58-3693), and the base fabric has a molecular weight of 500 to 500 as a resin component. 1000
Those in which a viscous synthetic resin of 0 (polybutene, polybutylene, etc.) is attached (Japanese Utility Model Publication No. 59-171665) are known.

[0004]

However, the conventional one disclosed in Japanese Utility Model Laid-Open No. 172574/1979 has a thick adhesive layer formed on the surface of the base cloth, and therefore is not suitable for capturing dust. Although suitable, it has a problem that the pressure-sensitive adhesive layer interferes and the surface to be coated and the like cannot be effectively wiped.

Further, the one disclosed in the above Japanese Patent Publication No. Sho 58-3693 is a mixture of the above-mentioned three components such as trichloroethane containing chlorine for the purpose of impregnating a base cloth with the above-mentioned polymer compound, modified natural resin and oil wax. Since the base cloth is dissolved in a hydrocarbon solvent consisting of, and the base cloth is dipped in this solution, trichloroethane is volatilized in the dipping process, which is not preferable for the health of workers and environmental protection. It should be noted that trichloroethane is listed as one of the main causes of destroying the ozone layer surrounding the earth.

Further, the molecular weights of those disclosed in Japanese Utility Model Laid-Open No. 59-171665 have a molecular weight of 500-10.
Since the viscous synthetic resin having a viscosity of 000 is once dissolved in a chlorine-based solvent such as trichloroethane and the base cloth is immersed in this solution to impregnate the viscous synthetic resin, the same problems as described above are encountered. have.

The present invention has been made in order to solve the above problems, and it is possible to effectively wipe the surface to be wiped, and dust generated from the surface to be wiped by wiping. It is an object of the present invention to provide a cleaning cloth that effectively adsorbs water and has no problems in health and environmental protection.

[0008]

In the wiping cloth according to claim 1 of the present invention, a base cloth made of a woven cloth, a non-woven cloth or a knitted cloth is impregnated with an adhesive resin containing an additive. The above-mentioned adhesive resin is one of an acrylic resin emulsion, a vinyl acetate resin emulsion, and an acrylic vinyl acetate copolymer resin emulsion. is a combination of two or more, the additives are alcohols state, and are a combination of more than one kind or two kinds of plasticizers and rosin esters, said Emma
10 parts by weight to 60 parts by weight with respect to 100 parts by weight of Rougeon
The one in which the additive is characterized that you have been mixed.

The cleaning cloth according to claim 2 of the present invention is the cleaning cloth according to claim 1, wherein the alcohols are divalent to pentavalent alcohols or a combination thereof. It is characterized by.

The cleaning cloth according to claim 3 of the present invention is the cleaning cloth according to claim 1 or 2, wherein the plasticizer is one or more of polybutene, phthalate ester and chlorinated paraffin. It is characterized by being a combination.

The cleaning cloth according to claim 4 of the present invention is the cleaning cloth according to claim 1, 2 or 3, wherein 10 to 60 parts by weight of the addition is added to 100 parts by weight of the emulsion. It is characterized in that the agent is mixed.

[0012]

According to the cleaning cloth of the above-mentioned claim 1, the adhesive resin impregnated into the base cloth made of a woven cloth, a non-woven cloth or a knitted material is acrylic, vinyl acetate or acrylic vinyl acetate. It is either an emulsion of each resin of the copolymer system or a mixed emulsion in which two or more kinds are mixed, and each of the above emulsions is naturally soluble in water, and is a harmful organic compound such as trichloroethane as in the past. By dipping the base cloth in the emulsion without using a solvent, it is possible to easily impregnate the base cloth with the resin having an adhesive property.

The above-mentioned acrylic type, vinyl acetate type,
Emulsions of each resin of the acrylic vinyl acetate copolymer system have excellent adhesiveness when the water in the emulsion is volatilized, and effectively removes fine dust generated by wiping the surface of the object to be wiped. Since it adheres, dust does not scatter in the air, and the working environment can be kept clean.

Further, when the mixed emulsion is used, there is a drawback of each emulsion constituting the emulsion (in each single product, a resin film is formed in a state where the water in the emulsion is volatilized and the adhesiveness is lost). Generated) are complemented with each other, and excellent adhesiveness is maintained even after evaporation of water.

Further, since the above-mentioned mixed emulsion is mixed with an additive comprising a mixture of one kind or two or more kinds of alcohols, a plasticizer and a rosin ester, the base cloth is impregnated by the action of these additives. The tackiness of the resin is effectively retained for a long period of time.

Since the above-mentioned additive is mixed in the range of 10 to 60 parts by weight with respect to 100 parts by weight of the emulsion, the mixing ratio is appropriate, and the mixing ratio of the resin impregnated into the base cloth is The tackiness can be effectively maintained for a long period of time, the base fabric maintains appropriate flexibility suitable for wiping, and the resin does not migrate to the surface to be wiped. By the way, if the mixing ratio of the additive is less than 10 parts by weight, the resin impregnated in the base fabric is cured in a short period of time, making the wiping operation difficult and not effectively sticking dust. On the other hand, when the amount is 60 parts by weight or more, the resin is too soft and becomes sticky on the base cloth, and the resin is transferred to the surface to be wiped during wiping.

According to the cleaning cloth of claim 2,
The alcohols used as additives are dihydric to pentahydric alcohols or a combination thereof, and therefore these alcohols have excellent tackiness by themselves, and the water content in the mixed emulsion is Since it remains as a solvent other than water in a volatilized state, it is effective for maintaining the adhesiveness of the resin on the base cloth.

According to the cleaning cloth of the above-mentioned claim 3,
The plasticizer used as an additive is a combination of one or more of polybutene, phthalic acid ester and chlorinated paraffin, both of which are chemically stable and non-drying. It is effective in maintaining the plastic state of the resin over a period of time and maintaining the tackiness.

[0019]

EXAMPLES The present invention will be described in detail below based on examples. The woven cloth, the nonwoven cloth, or the knitted material is applied as the base cloth to the cleaning cloth of the present invention. As the woven fabric, a natural fiber, a synthetic fiber, or a blended product thereof woven according to a conventional method is used. For non-woven fabric,
A wet method in which pulp is used as a raw material and the pulp is treated in the same manner as papermaking, a needle punch method in which short fibers are used as a raw material to make a fluffy cloth with a needle punch, or a spunbond in which long fibers are used as a raw material Those manufactured by the method etc. are applicable. Further, as the knitted product, a knitted product obtained by knitting a natural fiber yarn such as a wool yarn, a synthetic fiber yarn or the like according to a conventional method can be applied.

Incidentally, in this embodiment, a gauze-like woven fabric in which synthetic resin fibers are plainly woven and coarsely woven is applied as the base fabric. Alternatively, a synthetic resin fiber may be used as a raw material, and a non-woven fabric formed into a felt shape by a needle punch method may be adopted as the base fabric. In order to stabilize the tackiness of the resin, an additive is mixed in advance with the tacky resin, and a mixture of the resin and the additive is applied to the base cloth to form a polishing cloth.

In the present invention, as the above-mentioned adhesive resin, an acrylic resin emulsion (including acrylic rubber emulsion), a vinyl acetate resin emulsion, and an acrylic vinyl acetate copolymer type resin are used. Any one kind of emulsion or a mixed emulsion in which two or more kinds are combined is applied.

The above acrylic resin emulsion is
As a monomer, ethyl acrylate, methyl acrylate,
Butyl acrylate and the like (acrylic acid alkyl ester in the case of acrylic rubber emulsion) are used, and these copolymers are formed by diffusing in water in a colloidal form. The vinyl acetate-based resin emulsion is formed by using vinyl acetate as a monomer and polymerizing it in warm water. Further, the acrylic vinyl acetate copolymer-based resin emulsion is formed by copolymerizing the acrylic acid and vinyl acetate as monomers, which are copolymerized in water. All of these emulsions are naturally water-soluble, and when water evaporates,
Only the sticky resin component remains.

It is convenient to mix the above three types of emulsions to form a mixed emulsion. The reason is that by mixing, the synergistic effect of mixing is added to the effect of each emulsion alone. Such a synergistic effect was found by conducting many combination tests of various emulsions.

That is, as a result of the test, when water is vaporized from the acrylic resin emulsion, the acrylic resin having excellent adhesiveness remains, but it is cured in a short time to form a film on the surface. Was found to be unsuitable as an adhesive for polishing cloths. Further, in the case of a vinyl acetate-based resin emulsion, it is difficult to uniformly impregnate the resin base cloth with the resin because the polymerization of the monomer excessively proceeds in the emulsion formation process and a nodule of the polymer is formed in water. It has been found.

Therefore, these two emulsions are mixed,
In addition, a three-part mixed emulsion, in which an emulsion of a resin of vinyl acetate vinyl copolymer system, which improves the impregnation property into the base cloth, is further mixed, is applied to this mixed solution. By doing so, no film is formed on the surface even when water volatilizes while maintaining the excellent adhesiveness of the acrylic resin, and the formation of nodule of vinyl acetate colloidal resin in water is suppressed. In addition, an excellent mixed emulsion was obtained by the synergistic effect of the three factors that the resin of the acrylic vinyl acetate copolymer system improves the impregnation property into the base fabric.

Then, an additive is mixed into the mixed emulsion as described above to form an impregnating liquid for supplying to the base cloth. As the additive, a divalent to pentavalent alcohol,
Any of the commercially available plasticizers and rosin esters,
Or a combination of them is applied.

First, the reason why dihydric to pentahydric alcohols are applied is that alcohols are inherently suitable as a solvent for dissolving the above emulsions, and by adding such alcohols to the emulsions, the emulsions can be mixed with each other. This is because uniform mixing is facilitated. Moreover, 2
This is because the dihydric to pentahydric alcohols themselves have appropriate viscosities and have the function of keeping the resin wet even after the water in the emulsion has evaporated.

As the dihydric alcohol, ethylene glycol, 1,2-propanediol, 1,3-
Propanediol, 1,2-butanediol, 1,3-
Examples thereof include butanediol, 1,4-butanediol, and 2,3-butanediol, examples of trivalent alcohols include glycerin, and examples of pentavalent alcohols include sorbitol. Each of the above alcohols may be used alone or in an appropriate combination.

As the plasticizer, polybutene,
Any of phthalates and chlorinated paraffins, or a combination thereof, is applied. The polybutene has a molecular weight of 25, mainly isobutylene.
It is a liquid polymer of 0 to 2500, and it is also called a synthetic non-drying oil, and the loss due to evaporation is extremely small. Therefore, it is a suitable additive for keeping the viscous resin in a wet state.

The phthalate ester is also an excellent plasticizer having the same properties as the polybutene. Specific examples of the phthalate ester include dimethyl phthalate, diethyl phthalate, dibutyl phthalate, dioctyl phthalate, di-2-ethylhexyl phthalate, octyldecyl phthalate, diisodecyl phthalate, and butylbenzyl phthalate. It is possible, and dioctyl phthalate is particularly preferable.

The chlorinated paraffin is a substance in which any hydrogen of the alkane-based straight chain saturated hydrocarbon is replaced with chlorine, and the one having 8 to 19 carbon atoms is a wax-like substance which is solid at room temperature. However, those having 20 to 32 carbon atoms are oily liquid at room temperature. In addition, in the present invention, the liquid material at room temperature is applied to the additive mixed in the resin emulsion. The chlorinated paraffin is compatible with various resins and has the same function as that of the polybutene.

In this embodiment, 100 parts by weight of a mixed emulsion formed by mixing an acrylic resin emulsion, a vinyl acetate resin emulsion, and an acrylic vinyl acetate copolymer resin emulsion. On the other hand, 10 parts by weight to 60 parts by weight of the above additive is mixed to form the impregnating liquid.

The reason why 10 to 60 parts by weight of the additive is mixed with 100 parts by weight of the mixed emulsion is that the impregnating liquid is applied to the base cloth when the content of the additive is 10 parts by weight or less. After that, the resin having a caking property is immediately started to cure in a state where the moisture is evaporated by drying and a film is formed on the surface, so that the function as a polishing cloth cannot be fulfilled.

When 100 parts by weight of the mixed emulsion is mixed with 60 parts by weight or more of the additive, the resin remains sticky even after the moisture is evaporated by drying. The surface of the base cloth impregnated with such a resin is in a state of being covered with a sticky resin, and when wiped with such a polishing cloth, the resin moves to the surface to be wiped,
On the contrary, this causes a problem that the surface to be wiped is contaminated with the resin.

Even if 10 to 60 parts by weight of the additive is mixed with 100 parts by weight of the mixed emulsion, if it is in the range of 40 to 60 parts by weight, Since the base cloth becomes soft due to the effect of the resin having a caking property and becomes less stiff, and the caking force is slightly inferior, the mixing of the additive is preferably 10 parts by weight to 40 parts by weight with respect to 100 parts by weight of the mixed emulsion. It is preferable to set within the range of parts by weight. By doing so, the base cloth impregnated with the resin will be in a state in which extremely suitable caking property is imparted, and it is possible to obtain an excellent polishing cloth that adheres and removes fine dust generated during wiping. Become.

The method of applying the resin to the base cloth is not particularly limited, and the base cloth is immersed in the mixed solution of the above-mentioned mixed emulsion of the resin and the additive for a predetermined time to impregnate the base cloth with the resin. Alternatively, the mixed solution may be spray-supplied on the surface of the base cloth. After the adhesive resin is applied to the base cloth in this manner, the base cloth is loaded into the drying chamber heated to an appropriate temperature for a predetermined time and the moisture is evaporated to wipe the cleaning cloth according to the present invention. Is obtained.

The resin having the above-mentioned caking property, which is impregnated in the obtained wiping cloth, does not become dry due to the action of the additive and maintains the tackiness for a long period of time. The function to remove the dust generated from the stickiness lasts for a long time.

[0038]

As described above in detail, the cleaning cloth of the present invention is a cleaning cloth obtained by impregnating a base cloth made of a woven cloth, a non-woven cloth or a knitted cloth with an adhesive resin containing an additive. The wiping cloth, wherein the resin having tackiness is one or more of an acrylic resin emulsion, a vinyl acetate resin emulsion, and an acrylic vinyl acetate copolymer resin emulsion. The additive is a combination of one or more of alcohols, plasticizers and rosin esters.

Accordingly, the adhesive resin impregnated into the base cloth made of woven cloth, non-woven cloth or knitted material is a mixture of emulsions of acrylic, vinyl acetate and acrylic vinyl acetate copolymer resins. Each of the above emulsions constituting the mixed emulsion is naturally soluble in water, and the base cloth is immersed in the emulsion without using a harmful organic solvent such as trichloroethane as in the conventional case. By so doing, the base cloth can be easily impregnated with a resin having an adhesive property, which is convenient for health and environmental protection.

The acrylic type, vinyl acetate type,
Emulsions of each resin of the acrylic vinyl acetate copolymer system have excellent adhesiveness when the water in the emulsion is volatilized, and effectively removes fine dust generated by wiping the surface of the object to be wiped. Since it adheres, dust does not scatter in the air, and the working environment can be kept clean.

Further, one of alcohols, a plasticizer and a rosin ester is added to the above mixed emulsion,
Alternatively, since an additive composed of a mixture of them is mixed, the tackiness of the resin impregnated in the base cloth is effectively maintained for a long period of time by the action of these additives.

When alcohols used as the above-mentioned additives are divalent to pentavalent alcohols or a combination thereof, these alcohols have excellent tackiness by themselves, and moreover, the above mixture is used. Since water in the emulsion remains as a solvent other than water in a state of being volatilized, it is effective for maintaining the adhesiveness of the resin on the base cloth.

If one or a combination of two or more of polybutene, phthalic acid ester and chlorinated paraffin is applied as the plasticizer used as the above additive,
Since they are both chemically stable and non-drying, they maintain the plastic state of the resin for a long time,
It is effective in maintaining the tackiness.

If the additive is mixed in the range of 10 to 60 parts by weight with respect to 100 parts by weight of the mixed emulsion, the tackiness of the resin impregnated in the base cloth is maintained for a long period of time. It is possible to maintain it effectively, and the base fabric maintains appropriate flexibility suitable for wiping,
Moreover, the resin does not migrate to the surface to be wiped, which is convenient in terms of maintaining the adhesiveness of the resin and the wiping operation with a polishing cloth.
