DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of a disposable cleaning article according to the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a cleaning tool 2 to which a dirt wiping sheet 1 as a disposable cleaning article is attached. The cleaning tool 2 includes a plate-shaped head 3 and a rod-shaped handle 4. The wiping sheet 1 is in contact with the bottom surface 3B of the head 3, and a pair of parallel side edge regions 16 is folded on the top surface 3A of the head 3 and is detachably fixed by a clip 8. The cleaning tool 2 in such a state is used by holding the handle 4 and rubbing the floor surface with the wiping sheet 1.

The wiping sheet 1 shown in a partially cutaway perspective view in FIG. 2 has an abutting surface on the floor facing upward, and the side edge region 16 folded in FIG. 1 is developed to the side. The wiping sheet 1 has a side edge region 16 parallel to each other and a side edge region 16.
A base layer 21 for contacting the head bottom surface 3B, and a dust trapping layer 22 superposed on one surface of the base layer 21. , The layer 2 being superimposed on the dust trapping layer 22
2 is partially covered. For the base layer 21, a thermoplastic synthetic film having a thickness of 0.05 to 0.3 mm or a basis weight of 150 to 1,000 g /
A non-woven fabric made of m ² thermoplastic synthetic fibers (staple fibers) is used. The dust trapping layer 22 is rich in cushioning properties such as a cotton layer obtained by uniformly opening a tow composed of continuous filaments of thermoplastic synthetic fibers having a fineness of 1 to 25 denier to form a web, and cutting the web to a required size and thickness. ,
Having a basis weight 150~3,000g / m ^2. Cover layer 2
For No. 3, a nonwoven fabric made of thermoplastic synthetic fibers (staple fibers) having a basis weight of 30 to 500 g / m ² is used. The fineness of the synthetic fibers used for the base layer 21 and the cover layer 23 is not particularly limited, but the cover layer 23 is made of a fiber such that when the floor is rubbed, the fiber movement is smaller than that of the filament of the dust trapping layer 22. (Staple fiber)
Bonding or entanglement with each other by melt bond method, binder bond (chemical bond) method, spunlace method,
A nonwoven fabric obtained by a needle punch method, a spun bond method, a melt blown method, or the like can be used.

In such a wiping sheet 1, the dust trapping layer 22 is arranged in the center region in the width direction of the base layer 21 excluding the side edge regions 16, and the individual filaments 22 A are parallel to the side edge regions 16, and are located between the end edge regions 14. Extend continuously. The cover layer 23 has substantially the same shape and size as the base layer 21, and has a plurality of openings 24 in a portion overlapping the dust trapping layer 22. The opening 24 reduces the total length of at least a part of the plurality of filaments 22A located therein by 1 /.
The length L in the direction between both end edge regions 14 that can be exposed, and both side edge regions 16 of at least 5 mm or more.
And a width W between them. The number of the openings 24 may be plural or singular, and there is no particular restriction on the arrangement pattern when there are plural openings. It is preferably 20 to 80%. When the number is one, the base layer 21
Is preferably arranged at the center. The cover layer 23
Can be made larger or smaller than the base layer 21 as necessary.

FIG. 3 is a partially enlarged plan view of the wiping sheet 1. The base layer 21 and the dust trapping layer 22 overlapping on the inside of the opening 24 are thermally welded under pressure in a first welding area 26 intermittently arranged between the both edge areas 14, and the heat is welded from the periphery of the area 26. It has a thin film shape. The first of the illustrated examples
The welding area 26 is also intermittently arranged between the side edge areas 16 (see FIG. 1), but can be extended to reach the both edge areas 16 if necessary.

The base layer 21, the dust trapping layer 22, and the cover layer 23, which overlap with each other outside the opening 24, are welded under pressure in a second welding area 27 intermittently arranged like the welding area 26,
The area 27 has a thinner film shape than the surrounding area. However, in the both edge regions 14, the base layer 21, the cover layer 23, and the dust trapping layer 22 are welded under pressure in the relatively wide and long third welding region 28. The base layer 21 and the cover layer 23 overlap at both side edge regions 16 and are welded under pressure in a fourth welding region 29 (see FIG. 2).

FIG. 4 is an end view taken along the line IV-IV of FIG. In the wiping sheet 1, the dust trapping layer 22 is swollen inside the opening 24 compared to the outer peripheral area of the opening 24, and the welded portion 26 with the base layer 21 is formed in the dust trapping layer 22 around the portion 26. Is recessed with respect to the top surface portion 31 of the slab. Outside the opening 24, the base layer 21 and the cover layer 23 sandwich the dust trapping layer 22, and the cover layer 23 is at a position lower than the top surface 31. Further, the welding portion 27 of the base layer 21, the dust trapping layer 22, and the cover layer 23 is recessed with respect to the top surface of the cover layer 23 around the portion 27. Therefore, the wiping sheet 1 attached to the cleaning tool 2
First, the dust trapping layer top surface portion 31 contacts the surface to be cleaned.
When the cleaning tool 2 is strongly pressed against the surface, the top surface of the cover layer 23 contacts the surface together with the top surface 31. In this way, the layer 22 becomes the first dust trapping layer,
Layer 23 becomes the second dust trapping layer. These layers 22 and 23
Can be impregnated with an oil agent so that dust easily adheres thereto, and the cover layer 23 can be coated with an adhesive instead of the oil agent.

In the wiping sheet 1 configured as described above, if it is not necessary to strongly rub the surface to be cleaned,
The first dirt trapping layer 22 exposed in the aperture 24 can be used. When the surface is very dirty and it is desired to rub strongly, the second dust trapping layer 23 which is a cover layer can be used.

If the dust is particulate and a large contact area cannot be obtained with the cover layer 23, even if the cover layer 23 is coated with an adhesive, May be difficult to capture. However,
In the wiping sheet 1, each of the exposed filaments 22 </ b> A of the dust trapping layer 22 relatively freely moves between the welding portions 26, and the dust can be taken into the dust trapping layer 22. The taken-in debris is not surrounded by a large number of filaments 22A, and does not easily fall off the wiping sheet 1 and does not come into contact with the floor, so that the debris damages the surface to be cleaned. Nothing.

The welded portions 26 and 27 are harder than the dust trapping layer 22 and the cover layer 23, and may easily scratch the floor or the like. However, in this wiping sheet 1,
These portions 26 and 27 are used as the dust trapping layer 22 and the cover layer 2.
Since it is in a concave state with respect to No. 3, there is no possibility of such abrasion.

The wiping sheet 1 acting as described above is
If the floor is moved by moving in the direction perpendicular to the filament 22A, dust can be scraped off by the filament 22A, and the dust can be easily taken into the trapping layer 22. Therefore, it is preferable that the filament 22 </ b> A of the wiping sheet 1 attached to the head 3 in FIG. 1 extends in the longitudinal direction of the head 3.

FIG. 5 shows an embodiment of the present invention.
FIG. The wiping sheet 1 has a dust trapping layer 22 on both upper and lower surfaces of a base layer 21 and a cover layer 23 covering the layer 22. The upper and lower dust trapping layers 22 and the upper and lower cover layers 23 are located at the same portions 26 and 27 with respect to the base layer 21.
Welded. If one side of the wiping sheet 1 becomes dirty, the wiping sheet 1 can be turned over and the other side can be used.

In the present invention, the base layer 21 and the cover layer 2
When a nonwoven fabric is used for No. 3, natural fibers and regenerated fibers can be used up to 30% of their weight. In order to join the base layer 21, the dust trapping layer 22, and the cover layer 23, besides using a welding technique, an adhesive technique using a hot melt adhesive or the like can also be used. When the opening 24 of the cover layer 23 is small, it may not be necessary to join the base layer 21 and the dust trapping layer 22 inside the opening 24. A thermoplastic synthetic film may be used for the cover layer 23 in addition to the nonwoven fabric. If irregularities are formed on the surface of these materials, the effect of scraping dirt on the floor surface is enhanced.

[0018]

The cleaning article according to the present invention is composed of a bulky dust trapping layer made of filaments and a cover layer overlapping the trapping layer. Can use a layer of filament, and when the area to be cleaned is heavily soiled and needs to be rubbed strongly, a cover layer can be used. In addition, particulate dust that does not easily adhere to the cover layer can be taken into the filament layer.
