Description

DETAILED DESCRIPTION OF THE INVENTION The dry cleaning agent of the present invention is prepared by sprinkling a powder containing detergent and an appropriate amount of moisture on a contaminated object, and then rubbing it into the contaminated object with a brush.
This relates to a cleaning material similar to dry cleaning, which is performed by drying for 0 to 3 minutes and then sucking it up with a vacuum cleaner.

The cleaning agent of the present invention is mainly used for carpets, but has the characteristic that it can be widely used for tatami mats, leather, tiles, decorative mortar, fur, etc.

The carrier constituting the dry cleaning agent of the present invention has a Mohs hardness of 4.5.
~5. Consisting of silica particles with a particle strength of 3.5% or less and a particle size of 10 to 200 mm and organic short fibers with a length of 10 to 200 mm.

When using a Shigeru type cleaning agent, the degree of mechanical abrasion differs between hair and synthetic fibers of the substrate to be cleaned, such as carpet, and it must be used accordingly.

That is, a dry cleaning agent made of a carrier having hardness exhibits an excellent effect on cleaning power, but there is a risk of damaging the carpet. On the other hand, dry cleaning agents made with carriers having European hardness pose no risk of damaging carpets, but do pose problems in cleaning power. From this point of view, the present inventors have developed a method that does not cause damage to any base material,
Moreover, in order to obtain a dry cleaning agent with excellent cleaning power, we conducted extensive research and found that the Mohs hardness is 4-4.5 and the particle strength is 3.5.
% or less, silica particles with a particle size of 10 to 200 peaks and a length of 10 to 200
An average apparent specific gravity of 0.2 to 0.8 made by mixing 200% organic short fibers in an optimal ratio depending on the substrate to be cleaned.
By using a porous carrier with an average maximum moisture content of 50 to 300%, we succeeded in creating a cleaning agent that has unprecedented cleaning power and does not damage the base.

That is, when the dry cleaning agent of the present invention is sprinkled onto a substrate (for example, a carpet) and rubbed with a brush, the hard component silica particles (Mohs hardness 4 to 4.5) in the carrier and the soft component organic matter are mixed. It is an ideal cleaning agent that mixes with short fibers and maintains the strong cleaning power of the hard components while protecting the base material through the action of the soft components. The blending ratio of silica particles and organic short fibers, which are components of the carrier of the present invention, differs depending on the carpet fibers and the weaving method of the carpet, but the organic short fiber component is 5 to 95% by weight, preferably 20 to 70% by weight.

In general, the cleaning effect in cleaning work is due to the synergistic effect of the chemical cleaning power of the cleaning agent and the physical cleaning power of the washing machine, washing machine, hands, brushes, etc., and the effectiveness of each is about 50-50. It is said that

In order to effectively exhibit the above-mentioned physical cleaning power in the dry cleaning agent carrier of the present invention, it is necessary to mix a hard component to an extent that does not damage the substrate to be cleaned, and to peel off dirt attached to the substrate. can improve cleaning power.

Further, the organic short fiber component plays a role of wiping off dirt peeled off from the base material due to the physical detergency of the hard carrier component and protects the carpet base material. The blending ratio of the carrier component of the dry cleaning agent of the present invention varies depending on the fiber of the carpet and the method of binding. For example, in the case of pure wool carpet, organic short fiber components are the main component, and in the case of synthetic fibers, especially nylon fibers, hard fiber components are used. By blending mainly particle components, excellent detergency effects and carpet base protection effects can be obtained.

Mohs hardness of silica particles is 4.5 to 5 (measured by Mohs hardness meter), particle strength is 3.5% or less (Japanese Industrial Standard JI
The regulations for SK1464 industrial desiccant) are because when scrubbing with a brush or the like during cleaning, if silica particles become fine particles with a particle size of 10 or less, they will penetrate deep into the substrate to be cleaned, such as carpets, and cannot be easily recovered. It is.

In addition, as an organic short fiber component, for example, the length is 10 to 20
Pulp flock (for paper making) with a diameter of 0 French and 5 to 50 French
, human silk flock, cellulosin, etc. are used.

Next, all kinds of surfactants (anionic, nonionic, cationic,
amphoteric), soap, etc. are used.

Furthermore, builders, solvents, fluorescent dyes, enzymes, bleaching agents, bactericidal agents, and the like can be contained as appropriate and necessary. Examples of dry cleaning agents of the present invention that have excellent cleaning power and do not damage substrates are listed below in Table 1 as Prescription Examples 1 to 8. Table 2 lists performance test results for cleaning agents based on Prescription Examples 9 to 12 as symmetrical examples. show.

These cleaning agents are made by thoroughly mixing silica particles and short fibers using a dry blender, then adding detergent and water, and if necessary, builder, solvent, fluorescent dye, enzyme agent, bleach, disinfectant, etc. Manufactured by adding.
