BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning sheet body having an adhered surface adhered to an object to be cleaned and a cleaning method using the cleaning sheet body.

[0002]

2. Description of the Related Art Conventionally, the problems to be solved by the invention
Various cleaning agents and cleaning tools have been used to remove terrible dirt, dirt that is difficult to remove, and the like on an object to be cleaned. However, if a cleaning agent having a strong chemical action is used, the cleaning target may be chemically damaged, and if a cleaning tool for physically removing dirt is used, the cleaning target may be physically damaged. There is a risk.

The present invention has been made in view of the above problems existing in the prior art, and an object of the present invention is to remove terrible stains, stains and the like from a cleaning target object. It is an object of the present invention to provide a cleaning sheet body and a cleaning method that can be effectively separated and that can easily perform a cleaning process on the separated dirt while preventing the cleaning object from being physically damaged.

[0004]

Means for Solving the Problems A cleaning sheet body of the present invention that achieves the above object is a sheet-like article having one surface as an adhesive surface, which can hold a cleaning liquid, and one side of which has the adhesive surface. In the state where the liquid-retaining layer that constitutes all or a part of the adhesive surface and the adhesive surface are adhered to the object to be cleaned, the cleaning liquid retained in the liquid-retaining layer is lost from the side opposite to the adhesive surface. It is characterized by comprising a preventive layer for preventing.

Further, in the cleaning method of the present invention, the above-mentioned cleaning sheet has a sticking surface which is wholly or partly formed on one side of the liquid retaining layer in a state where the liquid retaining layer contains a cleaning liquid. It is characterized in that it is adhered by being brought into close contact with an object to be cleaned.

In order to perform cleaning using this cleaning sheet member, the sticking surface, which is wholly or partially formed by one surface of the liquid retaining layer, is cleaned while the liquid retaining layer contains the cleaning liquid. Stick by sticking to the object. If left in this state for a considerable time, the preventive layer prevents the cleaning liquid in the liquid retaining layer from being lost from the side opposite to the sticking surface. Will be continuously applied to. Therefore, while using a cleaning agent having a strong chemical action to prevent chemical damage to the cleaning target, the cleaning liquid contained in the liquid retaining layer removes terrible stains and hard-to-remove stains on the cleaning target. It can be effectively separated from the object to be cleaned. The dirt separated in this manner physically damages the cleaning target object, for example, by being adsorbed to the liquid retaining layer, or by being wiped by the liquid retaining layer, or by being wiped by another cleaning material or the like. It is possible to easily perform the cleaning process while preventing this.

The cleaning sheet member may contain a cleaning liquid in the liquid retaining layer. In this case, the sticking surface can be used by sticking the sticking surface as it is to the object to be cleaned. However, when it is necessary to prevent the cleaning liquid from volatilizing, such as when it takes a long time to use it, a volatilization preventing means such as sealing is taken.

In order to make the liquid retaining layer of the cleaning sheet contain the aqueous cleaning liquid, the liquid retaining layer can be made to contain the aqueous cleaning liquid in advance. Alternatively, the cleaning sheet may be adhered to the cleaning target by sticking the sticking surface to the cleaning target by covering the cleaning aqueous liquid adhered to the cleaning target with the liquid retaining layer. . In addition, it is possible to preliminarily contain the cleaning aqueous liquid in the liquid retaining layer and to attach the cleaning aqueous liquid to the portion of the cleaning target where the sticking surface is stuck.

One surface of the cleaning sheet body of the present invention is a sticking surface for sticking to a cleaning object. The whole or part of the sticking surface is constituted by one side of the liquid retaining layer.

The liquid-retaining layer is capable of holding the cleaning liquid and is preferably composed of a fiber aggregate. As the fibers constituting the liquid retaining layer, in any case, it is preferable to use water absorbing fibers such as rayon and acetate. However, it is also possible to use a polymer material such as a hydrophilic polymer gel for the liquid retaining layer.

Examples of the case where the liquid retaining layer is composed of an aggregate of fibers include, for example, when the liquid retaining layer is a nonwoven fabric layer, when the liquid retaining layer is a waterproof paper layer, and when the liquid retaining layer is a woven fabric layer. And the like.

Further, as another example of the case where the liquid retaining layer is composed of a fiber aggregate, a large number of fiber bodies (single fiber-like fibers) in which the liquid retaining layer is projected toward the attachment surface are provided. And the base of these fibrous bodies is provided with an embedding fixing layer in which the embedding is fixed.
In this case, the embedded fixed layer may constitute the prevention layer. The protrusion height of the fibrous body from the embedded fixing layer can be, for example, about 0.1 mm to 1 mm. As the fibrous body, for example, a fibrous body of 0.5 denier to 65 denier can be used. The density per unit area of the fibrous body protruding from the embedded fixing layer is, for example, 40 g.
/ M ^{2 to} 300 g / m ² can be set.

In such a fibrous body, the ratio of the standing angle (the angle between one surface of the embedding and fixing layer and the axis of the fibrous body) with respect to the embedding fixing layer at the tip portion of 60 degrees or more is 60%. The above is preferable. In this case, since the base of the fibrous body is in an upright state in the embedding fixed layer and is embedded and fixed in that state, the self-sustaining force of the fibrous body protruding from the embedding fixed layer in the upright state is high. When the cleaning target object is wiped in the liquid retaining layer, the dirt on the cleaning target object is scraped off more reliably by the aggregate of fibrous bodies. In order that dirt on the object to be cleaned can be more reliably scraped off by the aggregate of fibrous bodies, the standing angle is preferably 70 degrees or more, and the ratio is 7
It is preferably 0 or 80% or more. More preferably, the standing angle is 70 degrees or more and the ratio is 70 or 8
It is 0% or more.

Such flocking can be performed by flocking the fibrous body to the embedded fixing layer by flocking. Such flocking is performed, for example, by providing a synthetic resin adhesive layer for forming an embedded fixing layer on a synthetic resin sheet or other sheet-shaped material to form a negative electrode, and having a large number of piles for flocking above the negative electrode. Position the positive electrode,
The positively charged pile is dropped on the synthetic resin adhesive layer in an upright state to embed the base of each pile in the synthetic resin adhesive layer, and then the synthetic resin adhesive layer is solidified to synthesize the fibrous base in an upright state. It can be carried out by embedding and fixing in a resin adhesive layer (embedding fixing layer).

As the above-mentioned cleaning liquid, one having a surface active action is preferable, and an aqueous liquid containing a surfactant is particularly preferable. Examples of such cleaning liquid components include:
Examples thereof include surfactants, water (purified water, etc.), ethanol, antibacterial or antibacterial agents, perfumes, deodorants and the like. Further, in order to increase the sticking force of the liquid-retaining layer composed of the aggregate of fibers to the object to be cleaned, it is possible to increase the viscosity of the cleaning liquid by adding a thickener to the cleaning liquid. It is also possible to use a cleaning liquid containing an organic solvent.

The preventive layer is for preventing the cleaning liquid held in the liquid retaining layer from being lost from the side opposite to the sticking surface when the sticking surface is stuck to the object to be cleaned. The prevention layer may cover almost the entire other side of the liquid retaining layer (the side opposite to the sticking surface). For example, the other side of the liquid retaining layer may be covered just or wider. The prevention layer may be made of a material such as a water-impermeable / water-insoluble synthetic resin that can prevent the cleaning liquid retained in the liquid retaining layer from leaking out and evaporating to the outside. More specifically, the prevention layer can be formed, for example, by laminating a synthetic resin film such as a polyethylene film on a liquid retaining layer formed of an aggregate of fibers such as the above-mentioned nonwoven fabric.

The cleaning sheet body of the present invention preferably has a flexible sheet shape as a whole.
In this case, even if the cleaning target has unevenness, it is easy to adhere the target by sticking the sticking surface to the cleaning target.
