Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a textile product, particularly a textile product which cannot be washed with a usual electric washing machine such as a carpet, a chair, a sofa, an automobile interior, a textile product for interior and interior use, or which cannot use a large amount of water. The present invention relates to a dry cleaning composition for cleaning. More specifically, the present invention relates to a dry cleaning composition that uses a soil storage carrier as a soil carrier instead of water in cleaning that cannot use a large amount of water.

[0002]

2. Description of the Related Art Detergents for textile products which cannot be washed by an electric washing machine, especially liquid or powder detergents are used for carpets and the like. The liquid type cleaning agent has excellent handleability and good spraying property, but after cleaning, it requires long drying until the carpet can be used again. On the other hand, a dry cleaning agent comprising a powdery or fibrous dirt storage carrier and a cleaning liquid such as a surfactant or water for improving the cleaning power is used for the carpet immediately after cleaning or by drying for a short time. Although it can be reused, there is a disadvantage that the dry cleaning agent remains on the carpet due to adhesion by the impregnated liquid component or entanglement of fibers, which impairs the aesthetics and feel. Various proposals have already been made for the composition of a dry cleaning agent (Japanese Patent Publication No. 50-33882, Japanese Patent Publication No. 54-27003, Japanese Patent Publication No. 59-43520, Japanese Patent Publication No. 60-4880). Japanese Patent Examination Sho 60-828
No. 0 and Japanese Patent Publication No. 61-16799) do not solve the above problems.

[0003]

Means for Solving the Problems The inventors of the present invention have conducted extensive studies to solve the above problems, and as a result, as a dry cleaning agent, a soil storage carrier selected from powders, granules or short fibers having a high water solubility is used. If a lump formed by aggregating with a molecular substance is used, even if the cleaning liquid is held in the dirt storage carrier, it does not have adhesiveness to the carpet, and there is no entanglement of fibers, and the residue of the dry cleaning agent on the carpet is greatly increased. The inventors have found that it can be improved and have completed the present invention.

That is, the product of the present invention comprises a dry cleaning composition comprising a lump containing substantially a water-insoluble powder, granules, and a dirt storage carrier selected from short fibers and a substantially water-soluble polymer substance. Is provided.

When the lump according to the present invention is prepared in the shape of a sphere, a disc, a straw or the like, the fluidity becomes better and the dispersion on the fiber product becomes easier. The size of the agglomerate is not particularly limited, but if it is about several mm, it can be prepared by a rolling type, a vibration type, an extrusion type granulator, or the like, and if it is several cm to several tens cm, a compression molding type granulator.

Further, the dry cleaning composition of the present invention can also be used without containing the cleaning liquid containing the above-mentioned surfactant or the like in a lump. In this case, either a method of spraying the lumps on the article to be cleaned and then spraying the cleaning liquid, or a method of spraying the cleaning liquid and then the lumps, or simultaneously spraying both of them can be applied.
