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.

There is also known a method of winding an adhesive sheet on a roll and rolling it on a treated surface such as a carpet to capture dust, but since the adhesive surface adheres to the treated surface, it can be used on a flat floor or the like. Can not be used for. In addition, the dust trapping effect of the adhesive sheet is significantly reduced once dust is attached, so it is necessary to peel off the adhesive sheet every rotation, which is very troublesome, and there is a problem that the processing surface and hands are easily soiled.

[Means for Solving the Problems] In order to solve the above problems, the inventors of the present invention have conducted extensive studies, and as a result, have found that a pressure-sensitive adhesive sheet having a specific pressure-sensitive adhesive force has a specific thread thickness and a specific mesh opening. It was found that a cleaning sheet capable of solving the above-mentioned problems can be obtained by laminating or joining mesh fabrics having the above, and further studies were conducted to complete the present invention.

That is, according to the invention of claim 1, the thickness of the mesh yarn is 0.1 to 2.0 mm and the mesh is formed on the adhesive surface of the adhesive sheet having the adhesive force to the steel plate of 100 to 5000 g / 25 mm width. The present invention relates to a cleaning sheet formed by laminating mesh materials having an opening size of 3.0 to 15 mm.

The pressure-sensitive adhesive sheet used in the present invention is obtained by applying a pressure-sensitive adhesive to a support such as a base paper (for example, paper, paraffin paper, etc.), a plastic sheet, a metal foil or a laminate thereof, and the pressure-sensitive adhesive is acrylic. Various types of pressure-sensitive adhesives such as system-based, rubber-based and epoxy-based can be used, but acrylic-based or rubber-based pressure-sensitive adhesives are preferable from the viewpoint of performance. In the cleaning sheet of the present invention, the pressure-sensitive adhesive sheet has a specific pressure-sensitive adhesive strength, that is, a value of 100 to 5000 g / 25 mm width in a test based on the JIS Z0237 (pressure-sensitive adhesive tape / pressure-sensitive adhesive sheet test) 180 degree peeling pressure-sensitive adhesive strength test method. Is required to be indicated. If the width is less than 100g / 25mm,
Poor dust trapping effect, while 5000g / 25mm
If the width exceeds the width, the pressure-sensitive adhesive may adhere to the treated surface even if the mesh material is devised, which is not preferable.

The mesh material used in the present invention is a mesh of natural fibers such as cotton, synthetic fibers such as polyester, polyolefin, nylon, acrylic, etc., and the shape of the yarn is a single yarn or a twisted yarn. Alternatively, it may be a drawn yarn or the like. However, the thickness of the mesh threads is 0.1 to 2. because of the relationship with the adhesive strength of the adhesive sheet.
0 mm and the mesh size is 3.0 to 15
mm is required. When out of the above range,
Depending on the type of dust, it becomes difficult to be trapped, and problems arise in terms of dust trapping effect, contamination of the treated surface, and ease of use.

According to a second aspect of the present invention, in the structure of the first aspect, a pressure sensitive adhesive sheet obtained by applying an acrylic or rubber pressure sensitive adhesive to the base paper is used.

According to a third aspect of the present invention, in the structure of the first or second aspect, a mesh material formed in a mesh shape by a single yarn, a twisted yarn, or a drawn yarn made of synthetic fiber is used.

Further, according to the invention of claim 4, the thickness of the mesh threads is 0.1 to 0.1 mm on the adhesive surface of the adhesive sheet having an adhesive force to the steel plate of 100 to 5000 g / 25 mm width.
5 mm and mesh size of 3.0 to 10
The present invention relates to a cleaning sheet for a hand roller formed by joining mesh materials having a size of mm.

Cleaning sheets for hand rollers are usually
Since many sheets are wound around the core tube and used, the thickness of the mesh thread is set smaller than the thickness of the thread of the cleaning sheet according to claim 1.

According to a fifth aspect of the present invention, in the construction of the fourth aspect, a mesh material formed of synthetic fiber single yarn is used, which uses an adhesive sheet obtained by applying an acrylic or rubber adhesive to the base paper. Used.

BEST MODE FOR CARRYING OUT THE INVENTION
For example, when it is attached to a cleaner with a handle or a tabletop cleaner and applied to the processing surface, various dusts on the processing surface wiped off by the mesh material are taken into the openings of the mesh and captured by the adhesive sheet. Further, this cleaning sheet exhibits a high dust trapping efficiency by combining three conditions of the adhesive force of the adhesive sheet, the thickness of the mesh thread, and the size of the mesh opening, without contaminating the treated surface, and It has excellent usability. In addition, the above three kinds of conditions can be appropriately selected according to the purpose of use within the specific range described above. For example, in the case of capturing a relatively large dust, the size of the mesh opening is increased, While increasing the adhesive strength, the thickness of the mesh threads may be increased so that the adhesive does not contaminate the treated surface. In addition, urethane on the back of the cleaning sheet,
An elastic material such as a sponge or a soft fiber layer may be attached to further enhance the dust capturing efficiency and usability.

Further, the mesh material has a function of wiping off stains on the treated surface, but it is possible to impart a multipurpose effect by holding a drug or the like on it. For example, addition of a surfactant or oil is useful for removing liquid or pasty substances adhering to the treated surface, and if antibacterial and antifungal agents are retained, the bacteria in the cleaning sheet will be It is also possible to suppress the reproduction of mold.

According to the second aspect of the present invention, the preferred acrylic or rubber adhesive is used for the adhesive sheet.
A cleaning sheet with better performance can be obtained.

According to the third aspect of the present invention, since the synthetic fiber which is preferable as the material of the mesh material is used, it is possible to obtain a cleaning sheet having higher performance.

According to the invention of claim 4, like the invention of claim 1, it is possible to obtain a cleaning sheet for a hand roller which has a high dust trapping efficiency and can be used even on a flat floor.
Since the thread of the mesh is set to be relatively small because it is wound on the core tube and used, surprisingly, the adhesive of the cleaning sheet does not strongly adhere to the floor and the usability is not impaired.

According to the invention of claim 5, a preferable one is selected as the kind of the adhesive and the material of the mesh material, so that a cleaning sheet for a hand roller having more excellent performance is provided.

The cleaning sheet of the present invention can be easily attached to a patterned cleaner, a desk cleaner, etc., and is extremely useful as a cleaning article for floors, floors, furniture, desks, etc. of homes, offices, work places, restaurants, etc. Is. In addition, as a hand roller, it has a great advantage in terms of usability as compared to conventional products and is extremely practical. The cleaning sheet of the present invention can take various forms depending on the shape of the cleaner or hand roller to be applied. Of course, the area of the adhesive sheet portion of the cleaning sheet may cover the entire surface of the cleaner head. However, for example, the cleaning sheet of the present invention is attached to a part of a conventional non-woven fabric sheet, and the cleaning sheet is provided on the cleaner head portion. The adhesive sheet portion of the cleaning sheet may be located in the concave portion. However, the area of the adhesive sheet portion is preferably 10% or more of the area of the cleaner head portion from the viewpoint of securing the dust capturing power.

EXAMPLES Next, the cleaning sheet of the present invention will be described in more detail based on specific examples and test examples, but the present invention is not limited thereto.

Example 1 As an adhesive sheet used in this example, a base paper having a width of 20 cm and a length of 30 cm was coated with an acrylic adhesive having an adhesive strength of J
IS Z0237 (Adhesive tape / adhesive sheet test) 1
700g by the test based on 80 degree peeling adhesion test method
It was applied to have a width of / 25 mm. Further, a twisted yarn made of polyester and having a thickness of 1.0 mm is knitted so that the size of the mesh opening is 5 mm × 5 mm, and the mesh material (width 25
cm, length 30 cm) was prepared and laminated on the pressure-sensitive adhesive sheet. 1 to 3 show the cleaning sheet 1 thus obtained. The mesh material 3 is laminated on the pressure-sensitive adhesive surface a of the pressure-sensitive adhesive sheet 2 in which the pressure-sensitive adhesive layer 22 is formed on the base paper 21, and the pressure-sensitive adhesive sheet 2 is provided on both ends 3 ′ of the width of the mesh material 3 for easy use. There is a part that does not overlap. In the figure, the thickness of the mesh threads is indicated by b, and the size of the mesh openings is indicated by c. When the above cleaning sheet was attached to a cleaner with a handle and used on a wooden floor, a single sheet can capture a large amount of all kinds of dust such as cotton dust, hair, bread crumbs, confectionery waste, granules, etc. It was very efficient compared to the sheet. Further, the adhesive was not used to stain hands and the treated surface was not contaminated, and the floor surface was smoothly slid, and the usability was excellent, and the sheet had sufficient strength.

Example 2 As a pressure-sensitive adhesive sheet used in this example, a rubber-based pressure-sensitive adhesive was applied to a base paper having a width of 16 cm and a length of 2 m according to JIS Z.
1100 g / 25 in a test based on the 180 degree peeling adhesive strength test method of 0237 (adhesive tape / adhesive sheet test)
It was applied to have a width of mm. In addition, a polypropylene-made thread with a thickness of 0.2 mm and a mesh opening size of 6 m
Mesh fabric (width 16c
m, length 2 m) was prepared and bonded on the pressure-sensitive adhesive sheet to obtain a cleaning sheet. Next, as shown in FIG. 4, the cleaning sheet 1 is wound around the core tube 4 to which the handle 5 is connected so that the mesh material 3 becomes the outer peripheral surface, and the hand roller 6
And When this hand roller was used on a wooden table with scattered food waste, the effect of the mesh fabric did not cause the adhesive to adhere strongly to the treated surface, and the feeling of use was smooth. It was easier to peel off the cleaning sheet than the adhesive sheet used for. In addition,
Although the conventional pressure-sensitive adhesive sheet can be applied to the carpet, the pressure-sensitive adhesive is strongly adhered to the treated surface and cannot be used on a flat table.

Embodiment 3 Next, an example will be described in which the cleaning sheet of the present invention is positioned in the recess provided in the cleaner head portion. FIG. 5 is a perspective view of the cleaner head portion 8 of the cleaner 9 with a handle as viewed from the contact surface side with the processing surface. At the center of the non-woven fabric 7, the adhesive sheet 2
The cleaning sheet 1 of the present invention having the mesh fabric 3 laminated thereon is attached to the cleaner head portion 8 as a replacement sheet, and at that time, the cleaning sheet 1 is mounted in the central recess of the cleaner head portion 8. It

Test Examples Various cleaning sheets of the present invention shown in Table 1 were prepared according to Examples 1 and 2, and the following various performance tests were carried out. The results are also shown in Table 1. (1) Dust capture test Approximately 5 g of bread crumbs of various sizes are sprinkled on a 1 m square wooden board, and a cleaning sheet with a handle or a hand roller is attached to the sample cleaning sheet, and the test sheet is wiped evenly over the entire surface once. The amount of bread crumbs captured was investigated. The results were visually evaluated according to the following criteria. ◯: Almost all bread crumbs are caught. △: Bread crumbs are trapped regardless of size, but some are left untrapped. ×: Only small bread crumbs are trapped, and they easily fall off. (2) Usability test Treatment Items such as adhesion / contamination (A) of the adhesive to the surface, easiness of attachment / replacement of the sheet, and cleanliness (B) were evaluated, and the results were evaluated according to the following criteria. ◯: Very good usability of the test item Δ: Excellent usability of the test item ×: Poor usability of the test item

[0026]

[Table 1]

As a result of the test, the cleaning sheet of the present invention showed a high dust trapping power and was very excellent in usability. On the other hand, the conventional control product, for example, the sheet made of only the non-woven fabric (Control 1), has a poor dust trapping power.
The pressure-sensitive adhesive sheet (Control 2) on which the mesh fabric was not laminated or joined had a problem in terms of usability such as contamination of the treated surface. Further, those which do not satisfy any one of the conditions of the adhesive strength of the pressure-sensitive adhesive sheet, the thickness of the mesh thread, and the size of the mesh opening (Controls 3 to 8) are inappropriate and are useful only after three kinds of conditions are combined. It is clear that a good cleaning sheet can be obtained.
