It functions as an attachment part when attached to and used.

  A large number of cutting portions 4 are formed on the cleaning surface forming sheet 3. The cutting portion 4 is formed by applying a cutting blade to the cleaning surface forming sheet 3 and cutting it into a line with a predetermined width, and is usually called a cut.

  A tensile force is applied to the cleaning surface forming sheet 3, and the cleaning surface forming sheet 3 is joined to the base material sheet 2 while being pulled. As shown in FIG. 5 and FIG. 6 by this pulling force, the cutting edge 5 rises to form a projection 10, and an opening hole 6 is formed between the cutting edges 5.

  As shown in FIG. 4, the cut edge 5 means a cut end surface generated by cutting the cleaning surface forming sheet 3. FIG. 4 shows the cut portion 4 in a state before a tensile force is applied to the cleaning surface forming sheet 3. When the cut portion 4 is a cut, there is substantially no gap in the cut portion 4, but in order to make the expression in the drawing easy to understand, a gap is provided in FIG. ing.

In the present invention, the cleaning surface forming sheet 3 before applying a tensile force is shown in FIG.
As shown in the figure, the cleaning surface forming sheet 3 is provided with a large number of cutting portions 4.

The pressing plates 8 and 9 are respectively applied to the one side portion 3a and the other side portion 3b of the cleaning surface forming sheet 3, and the pressing plate 8 is pulled in the arrow C direction while pressing from above. In this way, one side 3a of the cleaning surface forming sheet 3 is pulled in the side direction. Specifically, it pulls in the downward side direction (arrow C direction).
At the same time, the presser plate 9 is pulled in the direction of arrow D. In this way, the other side 3b of the cleaning surface forming sheet 3 is pulled in a direction opposite to the pulling direction in the one side 3a. Specifically, it is pulled in the upward side direction (arrow D direction).

As described above, by pulling the cleaning surface forming sheet 3 in the directions of arrows C and D, as shown in FIG. 3, the inclination angle of the cutting portion 4 varies, and one side 3 a or the other side of the cleaning surface forming sheet 3 is changed. The portions 3b are arranged in a direction in which the inclination angle with respect to the side direction (the direction along the directions of the arrows C and D) is reduced.
In FIG. 3, the arrangement direction of the cut portions 4 after applying a tensile force to the cleaning surface forming sheet 3 is substantially parallel to the side direction of the one side portion 3 a or the other side portion 3 b of the cleaning surface forming sheet 3.

On the other hand, when a plastic sheet is used as the substrate sheet 2, polypropylene, polyethylene, polyester, or the like can be used as the material thereof.

  As the cleaning surface forming sheet 3, a non-woven sheet, a plastic sheet or the like can be used, but it is preferable to use a non-woven sheet. In this case, as the material of the nonwoven fabric sheet, the same material as the material of the nonwoven fabric sheet used for the base material sheet 2 can be used, and the constituent fibers of the nonwoven fabric are also used for the base material sheet 2 described above. The thing similar to the constituent fiber of a nonwoven fabric sheet can be used.

  Examples of means for joining the cleaning surface forming sheet 3 on the base sheet 2 include heat fusion, bonding with an adhesive, ultrasonic sealing, and the like, which can be appropriately selected depending on the sheet material. As an adhesive for bonding with an adhesive, a hot-melt adhesive, a two-component curable adhesive, a thermoplastic resin-based adhesive, and the like can be used. Among them, a hot-melt adhesive is used. Is preferred.

A method for producing the cleaning sheet 1 of the present invention using the cleaning surface forming sheet 3 shown in FIG. 2 will be described below.
The cleaning surface forming sheet 3 formed with a large number of cutting portions 4 is supplied to a pulling device 12 shown in FIG. 7 and subjected to a pulling process. The pulling device 12 includes a base 13, a pair of suction plates 14 and 15 movably provided inside the base 13, and a pair of press plates 8 and 9 provided movably above the base 13. Composed. Each of the suction plates 14 and 15 is provided with a number of suction holes, and these suction holes are connected to a suction pump (not shown) through a suction pipe 16.

  When the cleaning surface forming sheet 3 is supplied onto the base 13 of the pulling device 12, the press plates 8 and 9 move laterally from the left and right sides of the device and are set at predetermined positions. That is, when the pressing plates 8 and 9 reach the positions corresponding to the suction plates 14 and 15 at positions where the left and right side portions of the cleaning surface forming sheet 3 can be pressed, the lateral movement stops, The presser plates 8 and 9 move downward and come into strong contact with the left and right sides of the cleaning surface forming sheet 3.

The suction pump is operated to bring the suction plates 14 and 15 into a reduced pressure state. Thereby, the left and right side portions of the cleaning surface forming sheet 3 are sucked through the suction holes, and the cleaning surface forming sheet 3 is fixed on the base 13.
In this state, the presser plate 8 and the suction plate 14 move in the direction of arrow C in FIG. At the same time, the presser plate 9 and the suction plate 15 move in the direction of arrow D in FIG.

Since the pressing plate 8 strongly presses one side portion of the cleaning surface forming sheet 3, the one side portion of the cleaning surface forming sheet 3 is sandwiched between the suction plate 14 and the pressing plate 8 in the direction of the arrow C. Be pulled.
Similarly, since the pressing plate 9 strongly presses the other side portion of the cleaning surface forming sheet 3, the other side portion of the cleaning surface forming sheet 3 is sandwiched between the suction plate 15 and the pressing plate 9 and the arrow Pulled in the D direction.

In this way, the cleaning surface forming sheet 3 in which the cutting line direction of the cutting portion 4 as shown in FIG. 3 is changed by pulling the one side portion and the other side portion of the cleaning surface forming sheet 3 in opposite directions to each other. Is obtained.
As shown in FIG. 5 and FIG. 6, the cleaning surface forming sheet 3 has a large number of protrusions 10 formed by the cutting edge 5 when the cutting edge 5 rises, and between the cutting edges 5. And a large number of opening holes 6 are formed.

After completion of the pulling force application process for the cleaning surface forming sheet 3 as described above, the presser plates 8 and 9 are lifted and separated from the cleaning surface forming sheet 3 and then moved laterally toward the left and right sides of the apparatus. And return to the old position.
As a result, the pressing on the cleaning surface forming sheet 3 by the presser plates 8 and 9 is released, but the cleaning surface forming sheet 3 is continuously sucked by the suction plates 14 and 15, so that the posture after the tension is applied is maintained. (Fig. 3).

The base material sheet 2 is supplied to the cleaning surface forming sheet 3 that is sucked and fixed on the base 13 as described above (FIG. 8). After supplying the base sheet 2, a heat sealing hot blade 17 is set on the base sheet 2. When the hot blade 17 descends and strongly presses the base sheet 2, the base sheet 2 and the cleaning surface forming sheet 3 below the base sheet 2 are thermally fused to form the joint 11.
Since this thermal fusion process is performed in a state where the cleaning surface forming sheet 3 is sucked and fixed on the base 13, the cleaning surface forming sheet 3 maintained in the posture after applying the tensile force is joined to the base sheet 2. . That is, the cleaning surface forming sheet 3 in which a large number of protrusions 10 and opening holes 6 are formed by the cutting edge 5 is joined to the base sheet 2. In this way, the cleaning sheet 1 of the present invention is composed of the base sheet 2 and the cleaning surface forming sheet 3, and the cleaning surface forming sheet 3 is formed with a large number of projections 10 and opening holes 6 by the cutting edge 5. Is obtained.

  In applying a tensile force in the directions of arrows C and D to the cleaning surface forming sheet 3 as shown in FIG. 2, first, one side 3a of the cleaning surface forming sheet 3 is set in a direction orthogonal to the side direction ( That is, in FIG. 2, while pulling in the direction of arrow G), the other side portion 3b of the cleaning surface forming sheet 3 is in a direction opposite to the pulling direction (direction of arrow G) in the one side portion 3a (that is, in FIG. It is also possible to pull in the direction of arrow H, and then pull the one side 3a in the direction of arrow C and the other side 3b in the direction of arrow D.

Further, as described above, when the tensile force in the directions of arrows C and D is applied to the cleaning surface forming sheet 3, one side portion 3a of the cleaning surface forming sheet 3 is inclined in a diagonal direction having a predetermined angle with respect to the side direction. While pulling, the other side 3b of the cleaning surface forming sheet 3 may be pulled in a direction opposite to the pulling direction of the one side 3a.

  As shown in FIG. 13, the cleaning sheet 1 of the present invention is used by being attached to a cleaning tool 18 provided with a base plate 19 and a handle 28. That is, the cleaning sheet 1 is attached to the base plate 19 so that the base sheet 2 side of the cleaning sheet 1 is in contact with the surface of the base plate 19 of the cleaning tool 18, and the extension 2c of the base sheet 2 is attached to the base plate. The upper surface of 19 is locked to a jig (not shown), whereby the cleaning sheet 1 is fixed to the base plate 19.

The cleaning surface forming sheet 3 of the cleaning sheet 1 of the present invention has a large number of projections 10 formed by the cutting edge 5 so that dust is caught on the projection 10 during cleaning, and the dust is captured between the projections 10 and 10. Thus, according to the cleaning sheet 1 of the present invention, dust can be efficiently removed. Therefore, according to the cleaning sheet 1 of the present invention, not only minute dust can be removed, but also relatively large dust such as rice grains and bread crumbs can be reliably captured.
In addition, since a large number of opening holes 6 are formed between the cut edge portions 5, there is no risk that the dust once captured will fall off when dust is captured in the opening holes 6 between the protrusions 10, 10. It is possible to maintain the dust capture state and improve the cleaning efficiency.

Further, the dust caught on the protrusions 10 enters between the cleaning surface forming sheet 3 and the base sheet 2 through the opening hole 6 and can further prevent the captured dust from falling off.
Even if the dust captured by the protrusions 10 temporarily drops out, since there are many other protrusions 10 and opening holes 6 around the protrusions 10 and the opening holes 6, It is caught by another protrusion 10 and is captured between the protrusions 10 and 10 or is captured by the opening hole 6.

As another embodiment of the present invention, the arrangement pattern of the cut portions can be configured as a staggered arrangement pattern as shown in FIG.

The first cut portion rows 21a and the second cut portion rows 21b are alternately arranged to provide a plurality of cut portion rows, thereby forming a staggered arrangement pattern.

The cleaning surface forming sheet 3 provided with the cutting portions 20 in the arrangement pattern as described above is given a tensile force in a direction perpendicular to the side directions of the left and right side portions 3a and 3b.
That is, one side 3a of the cleaning surface forming sheet 3 is pulled in a direction orthogonal to the side direction (that is, the direction of arrow I in FIG. 9), and the other side 3b of the cleaning surface forming sheet 3 is pulled on the one side. Pulling in the direction opposite to the pulling direction (arrow I direction) in the portion 3a (that is, the arrow J direction in FIG. 9), thereby applying a pulling force to the cleaning surface forming sheet 3.
In order to perform such pulling in the sheet side direction (arrows I and J directions), the holding plates 8 and 9 in the pulling device 12 shown in FIG. The pulling process may be performed using a pulling device having a structure in which each of 15 is movable in the sheet side direction.

Due to the tensile force, a large tensile stress acts on the central portion of the cut portion 20, and therefore stress in the direction in which the cut portion edge portion 22 (FIGS. 10 and 11) rises (in the directions of arrows F ₁ and F ₂ in FIG. 11) is generated. To do. This stress, one of the cut edge 22 rises to direction of arrow F _1, the other of the cut edge 22 rises to the arrow F ₂ direction. As the cut edge 22 rises in this way, a projection 24 is formed by the cut edge 22.
Further, when the cut edge 22 is raised as described above, the gap between the cut edges 22 is expanded, and an opening hole 23 is formed as shown in FIGS.

As described above, the cleaning surface forming sheet 3 on which a large number of the protrusions 24 and the opening holes 23 formed by the cutting edge portion 22 are formed is joined to the base sheet 2, thus forming the cleaning sheet of the present invention.
The cleaning sheet in this embodiment also exhibits the same operational effects as the cleaning seat 1 in the above-described embodiment.

In the present invention, the shape of the cutting portion is not limited to the linear shape as in the above-described embodiment. For example, as shown in FIG. 12, the cutting portion 25 (FIG. 12a) having a curved shape is also used. Alternatively, the cut portion 26 (FIG. 12b) may have a shape in which a straight line is bent, or the cut portion may be configured by an array pattern including a combination of these shapes, including the straight shape in the above-described embodiment.
Moreover, as shown in FIG. 12 c, the cutting part may be a slit-shaped cutting part 27.

The cleaning sheet of the present invention is not limited to the case where the cleaning sheet is attached to the cleaning tool 18 as shown in FIG. 13 and applied to floor cleaning, and can also be used as a cleaning sheet for a handy mop.
That is, the insertion which inserts the leg part of a support tool between a base material sheet and a holding sheet, for example, joins the holding sheet which consists of a nonwoven fabric sheet to the surface on the opposite side to the cleaning surface formation sheet joining surface The cleaning sheet of the present invention can be configured as a handy mop cleaning sheet.
