Description

[Detailed description of the invention]

In the present invention, a powder containing detergent and an appropriate amount of moisture is sprinkled on the contaminated object, rubbed with a brush, etc., and after 20 to 30 minutes,
This invention relates to a cleaning agent used for so-called dry cleaning, which is performed by sucking it up with a vacuum cleaner. The cleaning agent of the present invention is mainly used for carpets, but can also be widely used for tatami mats, leather, tiles, decorative tiles, fur, etc. As a conventional dry cleaning agent, a carpet cleaning composition comprising a particulate polymeric substance and a liquid solvent is known (Japanese Patent Application Laid-Open No. 1986-68605), but the cleaning agent of the present invention has been further improved. It has excellent cleaning power for carpets of all fiber lengths from the surface of the carpet fibers to the base fabric, and also exhibits excellent performance in improving the wiping effect and recovering carrier powder containing dirt after cleaning. The carrier constituting the cleaning agent of the present invention has a particle size of 10 to 200.
This is a dry cleaning agent made by mixing μ particle-shaped aminoaldehyde resin powder with a composite carrier made of short organic fibers bound and/or adhered to the aminoaldehyde resin, and containing detergent and water. Generally, when cleaning carpet fibers, the dirtiness of the carpet fibers varies depending on the length of the pile and the density of the hair. Unlike hard, smooth surfaces, stains on carpet fibers include contaminants that adhere to the surface and contaminants that have penetrated deep into the carpet fibers, and carriers with simple shapes are not sufficient for cleaning all types of carpets. It was found that the cleaning performance could not be achieved and the recovery was also insufficient. Moreover, although conventional carpet cleaning agents have some degree of cleaning effect on contaminants that have penetrated deep into the carpet fibers, they have little cleaning effect on contaminants that have adhered to the surface of the carpet. The current situation is that we cannot hope for it. The inventors of the present invention have conducted extensive research in view of the current situation, and found that contaminants adhering to the carpet surface can be removed by using a composite carrier in which short organic fibers and aminoaldehyde resin are combined and/or adhered. The present invention was completed based on the knowledge that it intertwines with the fibers on the contaminated carpet surface and exhibits excellent cleaning performance. However, short fibrous composite carriers can "entangle" with the fibers on the surface of the carpet, allowing the carrier itself to penetrate deep into the carpet fibers.
It was found that cleaning performance was poor for contaminants that had penetrated deep into the carpet fibers. On the other hand, as a result of research to improve cleaning performance against contaminants that have penetrated deep into carpet fibers,
By using aminoaldehyde resin powder with a particle size of 10 to 200μ, a cleaning effect superior to that of conventional cleaning agents can be obtained, and by mixing it with the above composite carrier, it can be used for all kinds of weaves and pile lengths. Regardless of the conditions, a dry cleaning agent with excellent cleaning power and recovery performance could be obtained. The blending ratio in the cleaning agent of the present invention varies depending on the carpet weave, pile length, fiber density, and type of fiber, but for example, in the case of carpet fibers with short piles, the composite carrier component in the form of short fibers is mainly used. In addition, in the case of long-pile fibers, it is necessary to mainly mix particulate aminoaldehyde resin powder and adjust the mixing ratio as appropriate depending on the type of carpet. In other words, in the case of carpet fibers with short piles, a composite carrier with a length of 50 to 1000μ, which is made by bonding and/or adhering an aminoaldehyde resin to short organic fibers, has a particle size of 10
~150 for ~200μ aminoaldehyde resin powder
-800% by weight, preferably 300-500% by weight, and in the case of long pile carpet fibers, 5-800% by weight
It is used in an amount of 80% by weight, preferably in the range of 30-50% by weight. In addition, the blending ratio of organic short fibers and aminoaldehyde resin in a composite carrier in which aminoaldehyde resin is bonded and/or adhered to organic short fibers includes the effect of wiping off contaminants during cleaning and the contaminant after cleaning. This has a significant impact on the recovery rate of the carrier. That is, when the fiber is mainly composed of organic short fibers and the amount of aminoaldehyde resin bonded and adhered thereto is reduced, excellent performance is exhibited in wiping off contaminants during cleaning. On the other hand, if the amount of aminoaldehyde resin bonded and adhered to the short organic fibers is increased compared to organic short fibers, the recovery performance of the carrier containing contaminants after washing will be improved. Considering the excellent wiping effect of contaminants during cleaning, the organic short fibers should be in the range of 150 to 900% by weight, preferably 200 to 600% by weight, based on the aminoaldehyde resin to be bonded and/or bonded, and after cleaning. When taking into account the effect of improving recovery properties, the amount used is 5 to 90% by weight, preferably 10 to 60%. Generally, carpet fibers are made up of bundles of fine fibers gathered together to form a single carpet fiber.
Contaminants penetrate into the carpet fibers of the fine fiber bundle and are difficult to remove easily. The length of the short fibrous composite carrier in the cleaning agent of the present invention is determined in order to exhibit an excellent effect on stains in the fine fiber bundles on the carpet surface. Depending on the type of carrier, the length and the particle size of the particulate aminoaldehyde resin powder may match within the range of 50 to 200μ, but due to differences in the shape of the carrier, the cleaning performance and various performances may vary even with the same length. are different. Organic short fibers need to have an excellent "entanglement" effect with carpet fibers, and also have the ability to wipe away contaminants during cleaning.
Pulp flocs, cellulosin, etc. with a length of approximately 40 to 1000 μm are included. As the detergent contained in the cleaning agent of the present invention, all kinds of surfactants (anionic, cationic, nonionic), soaps, etc. can be used. Furthermore, builders, solvents, fluorescent dyes, enzymes, bleaching agents, bactericidal agents, and antistatic agents may also be contained as necessary. The following are examples of the dry cleaning agent of the present invention that exhibits excellent cleaning power and various performances on all types of carpets, and the performance of cleaning agents with formulations 1 to 8 in Table 1 as control examples. Table 2 shows the test results.

In the case of CS-5000-1 beige, the fibers on the carpet surface are cut uniformly at 8 m/m and the reflectance is measured. The method for measuring the reflectance of contaminated cloth is to measure the fibers on the surface of five uniformly contaminated specimens before cleaning.
Cut the cloth uniformly to 8 m/m, measure the reflectance, and perform statistical processing to determine the reflectance of the contaminated cloth. Similarly, the reflectance of uncontaminated cloth is similar to that of surface fibers.
The reflectance of a uniform cut of 8 m/m was measured, and the cleaning rate (%) was calculated by substituting these reflectances into the following formula. In the case of contract carpet CS-200-2 Gold, the fibers on the surface were cut at 2 m/m using the same procedure as above and the reflectance was measured. Cleaning rate (%) = Reflectance of contaminated cloth after cleaning - Reflectance of contaminated cloth / Reflectance of uncontaminated cloth - Reflectance of contaminated cloth x 100 (2) Recovery rate test New nylon contract car manufactured by Toray Industries, Inc.
