BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning tool used for business or household use.

[0002]

2. Description of the Related Art Conventionally, as cleaning articles, there are vacuum cleaners, brooms, mops, rags, chemical rags, etc., and they have been used properly according to the purpose or advantages and disadvantages of each method. In recent years, floors using wooden floor materials are increasing in apartment houses and the like, and disposable cleaning sheets that are easily attached to a cleaner with a handle and used like a mop and are easy to replace after use have become widespread. As a cleaning sheet, a flat cotton cloth or non-woven cloth impregnated with an oily substance is generally used. Although these are effective in removing fine dust, hair, bread crumbs, confectionery waste, granular materials, etc. It was difficult to wipe off the relatively large trash.
In addition, since the trapping force is weak, there is also a drawback that dust once trapped falls off due to vibration and the like to stain the surroundings. Therefore, JP-A-4-250130 and JP-A-4-31430
Japanese Patent Application Laid-Open No. 4-96724 discloses a structure in which a heat-shrinkable sheet and a non-woven fabric are partially joined and heat-shrinkable fibers are heat-shrinked to partially form convex portions. Discloses a mixture of ultrafine fibers having a weaving degree of less than 0.8 denier, but the dust trapping effect is not sufficient, and there are many problems in sheet strength and manufacturability.

On the other hand, for carpets and carpets, there is also known a method in which an adhesive sheet is wound around a roll and rolled on a treated surface such as a carpet to capture dust. However, the dust trapping effect of the pressure-sensitive adhesive sheet is not always sufficient for relatively large dust, and once dust adheres, the dust trapping effect remarkably decreases, so it is necessary to peel off the pressure-sensitive adhesive sheet every rotation. However, it has a problem that it is very troublesome and the processing surface, hands and clothes are easily soiled.
