Description

[Detailed description of the invention]

The present invention provides a powdered interior material cleaning composition, particularly an inexpensive and high-performance cleaning composition suitable for cleaning fiber interior materials such as carpets, wall materials, and fabric parts of furniture. Traditional shampoo cleaning requires specialized equipment, skilled personnel, and long drying times, and is typically performed over long periods in large commercial buildings. However, this alone is not sufficient for the maintenance and management of interior materials, especially carpets, and there are methods such as spraying, brushing, and suctioning a detergent solution as a partial maintenance between shampoo cleanings, and methods of soaking a pad with cleaning solution and wiping the interior materials. is used as a supplement. Although these methods make interior materials beautiful for a while, they are susceptible to re-contamination by the cleaning solution itself, and dry slowly.
Powder cleaning is expected to be a maintenance method for interior materials that solves the above problems. Powder cleaning refers to a method in which a cleaning composition in the form of powder is sprinkled, brushed, dried, and then sucked with a vacuum cleaner. Powder cleaning has also traditionally been carried out in small commercial buildings and homes due to its simplicity. However, conventional powder cleaning compositions include natural organic powders such as wood powder, inorganic powders such as stone powder, bentonite, and zeolite, or polyurethane, polystyrene, phenol-formaldehyde resins, and those described in U.S. Pat. No. 4,013,594. Some synthetic resin powders such as urea formaldehyde resin are shown, but the natural organic material powders color the objects to be cleaned, and the inorganic powders damage the objects to be cleaned.
In addition, the cleaning ability of both was unsatisfactory. In the case of synthetic resin powder, although the effectiveness was considerably improved, the high price was an obstacle to the widespread use of powder cleaning. In order to overcome the above-mentioned problems, the present inventors have conducted research into formulating powder cleaning compositions using various powders as raw materials, and as a result of their earnest efforts, they have completed the present invention. By using white non-fibrous cellulose acetate resin powder, the present invention does not get too wet, does not cause any damage or shrinkage to interior materials, does not cause discoloration of the object to be cleaned, and does not stain after powder cleaning. It provides a cleaning composition with low adhesion, that is, excellent antifouling properties, which contains white non-fibrous cellulose acetate with an average particle size of 10 to 200μ and a surfactant. A liquid selected from water, lower alcohols, or high boiling point hydrocarbons of 150°C or higher that can maintain an appropriate wet state and can be handled as a powder is added in an amount of 20 to 250 parts by weight per 100 parts of the resin powder. The gist of the invention is an interior material cleaning composition that is characterized in that it can be applied and removed by suction. The present invention will be explained below. White cellulose acetate is used in the present invention. If natural organic powders containing pigments such as wood powder are used, light-colored interior materials will be colored during cleaning, and inorganic powders may damage or whiten dark-colored interior materials. Conventional powder cleaning agents cause discoloration of interior materials, but since the present invention uses white organic powder, such drawbacks have been eliminated. As the cellulose-based resin powder used in the present invention, cellulose acetate hardly causes clogging of a vacuum cleaner when suctioned, is white, and is suitable as a powder for use in the present invention, and is inexpensive and has excellent effects. It will be done. The powder form is non-fibrous, such as spherical. The powder of the present invention has an average particle size of 10 to 200 μm, and if the particle size becomes larger, the contact with the object to be cleaned becomes poor and the cleaning effect decreases. Furthermore, if the particles become finer, some of them will remain on the object to be cleaned, reducing the efficiency of removal by a vacuum cleaner. Note that a small amount of white cellulose powder may be added as an supplement. The surfactant is preferably an anionic type, a nonionic type, or a mixture thereof. Anion types include sodium salts of organic acids with phenyl groups or _C10-18 aliphatic alkyl groups, such as lauric acid, stearic acid, palmitic acid, oleic acid, linoleic acid, myristic acid, lauryl sulfate, stearyl sulfate. Preferred are the sodium salts of the esters, palmityl sulfate, oleyl sulfate, linol sulfate, myristyl sulfate and alkylbenzene sulfonic acids. As nonionic type surfactants, sorbitan surfactants such as alkylphenol-polyoxyethylene ether, polyoxypropylene-polyoxyethylene ether, sorbitan monolaurate, and sorbitan monostearate are preferable. The amount of surfactant is 0.5 to 100 parts of the above cellulose resin.
It is preferable to mix 20 parts, but it may be used with other amounts. A liquid is applied to the above-mentioned blended composition. Suitable liquids for use in the present invention include water, lower alcohols such as methyl alcohol, ethyl alcohol, and isopropyl alcohol, and high-boiling hydrocarbons of petroleum fractions at 150° C. or higher. The liquid is added in an amount of 20 to 250 parts by weight, more preferably 40 to 200 parts by weight, per 100 parts of the resin powder, so that the composition can maintain proper wetness and can be handled as a powder. If no liquid is included, dirt on the interior material will not be absorbed by the powder during cleaning,
Moreover, the composition is thrown up, which is not favorable for the working environment. Furthermore, if too much liquid is applied, it becomes muddy or paste-like, which is inconvenient to handle, cannot be vacuumed as it is, and takes a long time to dry, which is inappropriate. The above-mentioned detergent formulation composition is stirred by a known method to uniformly disperse the ingredients. Note that the surfactant may be used after being dissolved in water in advance. Additionally, the cleaning composition of the present invention contains a small amount of styrene.
Antifouling agents such as maleic anhydride copolymer and diatomaceous earth, antistatic agents, fluorescent agents, fragrances, antibacterial and antifungal agents, and the like may be added. In the present invention, it is obvious that a remarkable effect can be obtained by using cellulose resin powder in particular, but by using a surfactant and a liquid together, when it comes into contact with the interior material, the adsorption level between the solid phase is reduced. As a result, dirt in the interior material is transferred into the cleaning composition. The cleaning composition of the present invention is usually sprayed at 50 to 100 g/m ² depending on the degree of dirt on interior materials such as carpets,
For example, it is brushed with a brush such as Concept 4000 manufactured by Clark Company in the United States. After brushing, the upholstery is generally left for a period of 40 minutes or less, during which time the dirt on the upholstery is transferred to the cleaning composition. After evaporation of the liquid component, the powder composition is removed with a vacuum cleaner to complete the cleaning. The present invention employs the above-mentioned method, which is a simple operation, does not overwet the fibers and dries easily, does not cause the interior material to be discolored during cleaning, and does not damage or shrink the fibers. In addition, since it is non-fibrous, it does not get tangled in piles, and no powder remains after being sucked in by a vacuum cleaner, so it has excellent stain resistance after washing. Repeated cleaning with the cleaning agent of the present invention improves the ability to remove stains. Despite having the above excellent characteristics,
The composition of the present invention is provided at a very low cost. Examples are shown below. Examples 1 and 2 The following compositions were thoroughly mixed to obtain a cleaning composition of the present invention. Parts indicate parts by weight. Example 1 Cellulose acetate (average particle size 100μ) 50 parts sodium lauryl sulfate salt 3 Water 46 Diatomaceous earth 1 Example 2 Cellulose acetate (average particle size 100μ) 40 parts Cellulose powder (average particle size 150μ ) 10〃 Lauryl sulfate sodium salt 2.5〃 Polyethylene-polypropylene oxide 0.5〃 Water 40〃 Isopropyl alcohol 5〃 Diatomaceous earth 2〃 Comparative examples 1 to 3 The following powders with approximately the same particle size were used in place of cellulose acetate in Example 1. I used my body. Comparative Example 1 50 parts of wood flour 2 35 parts of wood flour + 15 parts of bentonite powder 3 50 parts of urea formaldehyde resin The obtained Examples 1 and 2 and Comparative Examples 1 to 3 are powders that maintain an appropriate wet state and are portable. Sprinkle it on undyed white nylon tufted (level loop) carpet that has become dirty from actual walking at a rate of about 80 g/m ² , and after brushing it to evenly contact each part of the carpet, see Table 2. After standing for the indicated time, the powder was removed with a vacuum cleaner. The results obtained are also shown in Table 2.

[Table] However, A: Excellent, B: Good, C: Average, D:
Inferior.
The time after brushing is the time required for drying the above-mentioned cleaning composition by spreading it on the carpet and leaving it in a room at 20° C. and 60% RH. Damage and discoloration after washing mainly indicates damage to the pile portion and color transfer of the cleaning agent during shampooing. The cleaning performance indicates the ability to restore the brightness of the white carpet immediately after cleaning. Comparative Examples 1 and 2 used wood flour, which gave the carpet reverse coloring during cleaning, and also took a long time to dry after brushing. Furthermore, Comparative Example 1 had a particularly low cleaning ability, and Comparative Example 2 used an inorganic bentonite powder, which caused damage to the objects to be cleaned, such as piles. This is a particularly serious problem especially when cleaning furniture and the like. Comparative Example 3 did not damage the objects to be cleaned, and although the objects to be cleaned were colored during cleaning, the cleaning performance was quite good and was the best among known cleaning compositions. In both Examples 1 and 2 of the present invention, the time required for drying after brushing was short, the objects to be cleaned were not damaged or discolored, and the cleaning performance was extremely excellent. In addition, 8 white carpet samples during actual walking
We tried daily powder cleaning and tested the antifouling effect of the cleaning agent. The brightness ratio of the undyed white carpet sample before use is set as 100, and the brightness immediately before and after powder cleaning is shown. The results are shown in Figure 1. B is a case where no cleaning is performed at all. It is clear from FIG. 1 that Examples 1 and 2 have better antifouling effects than Comparative Examples 1 to 3. This fact is very important, as it is not only better than Comparative Example 3, which is the best known carpet cleaning agent, but also the manufacturing cost of Examples 1 and 2 is 40-60% of that of Comparative Example 3. By carrying out the present invention, it was possible to provide an inexpensive interior material cleaning agent with excellent performance.
