Abstract

PURPOSE:To make possible the cleaning of textile products which cannot be washed in ordinary electric washing machines nor by using a large amount o water by controlling the strength of a dry detergent composition comprising a lump of a stain-adsorbing carrier to be not disintegrable by the force applied during storage and transportation but disintegrable by the force applied during use. CONSTITUTION:A dry detergent composition comprising a lump of a stain- adsorbing carrier selected among powder, granule and staple, wherein the lump is not disintegrable by the force applied during storage and transportation but disintegrable by the force applied during use. If the lump is so prepared in strength that it is not disintegrable during storage and transportation but disintegrable by the stirring force of ordinary brushing (hand brush, polisher, etc.), the lump is disintegrated at the stage when it is brought into contact with a carpet by brushing, etc., so that it can exhibit a detergency equivalent to the dry detergent prior to being made lump. The composition can hence be kept compact during transportation and storage. In the control of the strength, a binder or disintegrating agent may be added as required.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to textile products, especially carpets, chairs, sofas.
1. This invention relates to a dry cleaning composition for cleaning textile products that cannot be washed with a normal electric washing machine or cannot use large amounts of water, such as textile products for automobile interiors and house interiors.

More particularly, the present invention relates to a dry cleaning composition that utilizes a dirt storage carrier as a dirt carrier in place of water in washing where large amounts of water cannot be used.

[Prior Art and Problems to be Solved by the Invention] Liquid or powder detergents are used for cleaning textile products that cannot be washed with electric washing machines, especially for carpets and the like.

Liquid type cleaning agents have excellent handling properties and good dispersibility, but require a long period of time to dry the carpet after cleaning before it can be used again.

On the other hand, dry cleaners that contain powdered or fibrous dirt storage carriers and cleaning liquids such as surfactants, water, etc. to improve cleaning power can be used to dry carpets immediately or in a short period of time after cleaning. However, due to adhesion between the powders due to the impregnated liquid component or entanglement of the fibers, the fluidity is poor, and it is difficult to reuse the textiles using a simple sprayer using a ten-bar, etc. There is a disadvantage that it is not possible to spread smoothly and uniformly using the method.

Furthermore, dry cleaning agents have a large specific volume, making them inconvenient to use and requiring a large space for transportation and storage.

Various proposals have already been made for compositions for dry cleaning agents (Japanese Patent Publication No. 33882/1983, Japanese Patent Publication No. 1983-33882,
No. 27003, Japanese Patent Publication No. 59-43520, Japanese Patent Publication No. 60-4880, Japanese Patent Publication No. 60-8280, and Japanese Patent Publication No. 61-16799) do not solve the above-mentioned problem.

[Means to solve the problem]

In order to solve this problem, the present inventors conducted extensive research and found that if dirt storage carriers selected from powders, granules, or short fibers are aggregated into agglomerates in dry cleaning agents,
We discovered that even if the cleaning liquid is retained in the dirt storage carrier, fluidity, that is, dispersibility, can be improved and compactness can be achieved.
The present invention has now been completed.

That is, the present invention provides a dry cleaning composition comprising an agglomerate of a dirt storage carrier selected from powders, granules, and short fibers, wherein the agglomerate does not disintegrate under the forces applied during storage and transportation, but does not disintegrate during use. The present invention provides a dry cleaning composition characterized by having the strength to disintegrate under applied force.

If this mass is made to have a strength that will not disintegrate during transportation or storage, but will disintegrate with the agitation force of ordinary brushing (hand brush, polyrusher, etc.), it will disintegrate when it comes into contact with the carpet during brushing, etc. However, it is possible to develop a cleaning power equivalent to that of a dry cleaning agent before it is made into a lump, and it is also possible to achieve compactness during transportation and storage. For this strength adjustment, a binder or a disintegrant can be added as necessary.

In addition, the strength that does not disintegrate before use, such as during storage or transportation, is defined as: (1) Place the part of the granulated product that does not pass through 32 mesh into a glass cylindrical container, and shake it up and down with an amplitude of 50 mm for 30 cycles for 1 minute. After 1 minute of exercise, the passing rate of 32 mesh sieves is 1.
0% or less, and the strength to the extent that it disintegrates with a hand brush means: 2) The part of the granulated product that did not pass through 32 mesh was applied with a normal hand brush at a load of 1.5 kg, and the strength was applied to the carpet. This means that the degree of disintegration of the granulated product when rubbed 60 times for one minute is 70% or more at a 32 mesh sieve pass rate. For example, 3) The amount of the granulated product that does not pass through 32 mesh is
Floor Bolisher-CMP-140E manufactured by ELECTRICWORKS LTD, brush size 40cm, 2
This means that when brushing on a carpet for 1 minute at 0 rpm, the degree of disintegration of the granulated product is 60% or more at a rate of passage through a 32 mesh sieve.

It is preferable that the strength is between 1) and 2) since it can be applied to both hand brushes and polyrushers.

Furthermore, if the lumps are prepared in a spherical, disc-shaped, straw-shaped, etc. shape, the fluidity will be better, and it will be easier to spread them onto textile products. There is no particular limit to the size of the lumps, but
If the size is about several mm, it can be prepared using a transfer type, vibration type, or extrusion type granulator, and if it is several cm to several tens of cm, it can be prepared using a compression molding type granulator. The size of the lump is about 0.7
It is preferably about 3 to 3 oz.

The dirt storage carrier used in the present invention may be powder or short fibers that have an average particle size or average fiber length of 400μ or less, preferably 20μ or more and 300μ or less, and that have dirt storage ability and are conventionally used in dry cleaning agents. I can do it.

For example, short fibers such as cellulose, rayon, and nylon, cellulose powder, porous powders such as polyvinyl alcohol, urethane, polyethylene, and polystyrene, powdered synthetic resin foams such as polypropylene, polyethylene, polystyrene, and aminoaldehyde resin, and their pulverization. Inorganic materials such as silica, zeolite, and silica can be used as the carrier, and cellulose powder is preferred.

A cleaning liquid containing one or more of the following cleaning components in an amount of 5 to 500% by weight relative to the carrier can be supported on the carrier.

The cleaning components used in the present invention include the following (
Solvents, surfactants, alkaline agents, etc. used as conventional cleaning agent components shown in i) to (iv) can be exemplified.

(i) Solvents Examples of the solvents include those shown in the following (1) to (6).

(1) Water (2) Alcohol (ethanol, isopropanol, etc.) (3) Polyhydric alcohol solvents (cellosolves, ethylene glycol, propylene glycol derivatives, etc.) (4) Hydrocarbon solvents (petroleum) ( 5) Halogenated hydrocarbon solvents (trichloroethane,
perchloroethylene, etc.) (6) Fluorinated solvents (Freon 113, etc.) (ii) Nonionic surfactants Nonionic surfactants include polyoxyethylene alkyl ether (alkyl group has 8 to 22 carbon atoms, presence or absence of branching) and the presence or absence of unsaturated bonds.The same applies to the following alkyl groups.Also, the degree of polymerization of oxyethylene is 3 to 1.
00, the same applies to the following polyoxyethylenes), polyoxyethylene alkyl phenyl ether, sorbitan mono-, di-, and tri-fatty acid esters (fatty acids having 8 to 8 carbon atoms)
22, regardless of the presence or absence of branches and the presence or absence of unsaturated bonds. The same applies to the following fatty acids), polyoxyethylene sorbitan mono-, di-, and tri-fatty acid esters, glycerin fatty acid esters, polyoxyethylene fatty acid esters, and the like.

(iii) Anionic surfactants Examples of anionic surfactants include sodium or potassium fatty acids, sodium, potassium, ammonium or alkanolamine salts of alkyl sulfates, sodium or potassium alkylhenzenesulfonates, sodium or potassium alkylnaphthalenesulfonates. , sodium dialkyl sulfosuccinate, sodium, potassium, ammonium or alkanolamine salts of polyoxyethylene alkyl sulfate, sodium polyoxyethylene phenyl ether sulfate, and the like.

(iv) Alkalies Examples of alkaline agents include alkanolamines, morpholine, and ammonia.

Furthermore, the cleaning liquid used in the present invention not only removes dirt, but also has the purpose of improving the finish of textiles and other objects to be cleaned. Textile products such as cationic surfactants, amphoteric surfactants, long chain fatty acid esters, water-based polyethylene, water-based polyurethane, water-based polyester, water-based nylon, polyvinyl acetate, etc., for the purpose of improving texture such as imparting elasticity and elasticity. An appropriate amount of a hand feel improver can be added.

Furthermore, the cleaning liquid used in the present invention may contain appropriate amounts of other additives such as chelating agents, dispersants, organic thickeners, and inorganic thickeners, and may also contain antibacterial agents, depending on the purpose. Rust inhibitors, dyes or pigments, fragrances, etc. may be added in small amounts.

The amount of the various conventionally known cleaning ingredients mentioned above is not particularly limited, but when the total content of non-volatile ingredients in the cleaning liquid is 20% by weight or more, these non-volatile additives may be added to the object to be cleaned. It remains on the surface and gives an undesirable finish such as stickiness and roughness. Therefore, the total content of non-volatile components in the cleaning liquid must be less than 20% by weight.

In addition, in order to spray cleaning agents, it is common to spread the carrier by hand or use a net-like carrier as before, but in addition to this, it is also possible to spread the cleaning agent automatically and uniformly in advance. By loading the detergent into a sprayer that can do this and spraying it, it is possible to obtain effective cleaning power with a small amount of detergent. This spreader can also be connected to a brushing device.

The cleaning composition of the present invention can also be used without containing the cleaning liquid consisting of the above-mentioned surfactant side in the carrier. In this case, any of the following methods can be applied: spraying the carrier onto the object to be cleaned and then spraying the cleaning solution, spraying the cleaning solution and then spraying the carrier, or spraying both at the same time.

〔Effect of the invention〕

The cleaning agent obtained by the present invention has a reduced volume due to the agglomeration of the dirt storage carrier, making it compact, and does not require a large space during transportation and storage, and is easy to handle, such as being easy to take in and out of the container. It has the characteristic of being convenient.

In addition, the fluidity is improved due to the agglomeration of the dirt storage carrier,
It also has the characteristics of good dispersibility and increased cleaning efficiency.

Furthermore, by selecting a strength that easily disintegrates with the agitation force of normal brushing operations, it has the characteristic that it exhibits the same cleaning power as a normal dry carpet cleaner before agglomeration.

This is a great advantage especially for sofas and carpets.
