[0008]
The cleaning tool sheet 1 of the present invention is configured by providing a large number of cut lines 3 in at least one nonwoven fabric sheet 2. The nonwoven fabric sheet 2 constituting the invention sheet 1 may be one sheet or a plurality of sheets. When using a plurality of nonwoven fabric sheets 2, they are used by superimposing the peripheral edges of nonwoven fabric sheets 2 of the same size. Even if the number of the nonwoven fabric sheets 2 is one, it can be used sufficiently as the cleaning tool sheet 1, but as will be described later, it has improved structure for capturing and retaining dust and dust and having a volumetric feeling as a whole. In order to do this, it is preferable to polymerize and use two or more non-woven fabric sheets 2. Usually, it is preferable to superpose two or three sheets.
[0009]
Examples of the material of the nonwoven fabric sheet 2 used in the present invention include a spunlace nonwoven fabric, a spunbond nonwoven fabric, a thermal bond nonwoven fabric, an air-through bond nonwoven fabric, a point bond nonwoven fabric, and the like. It can be used in combination. In particular, the spunlace nonwoven fabric and the thermal bond nonwoven fabric are preferable because when the cut 3 is provided, the cut surface is easily raised and a fluff structure is easily obtained.
[0010]
The shape of the sheet 1 of the present invention is generally rectangular or square, but is not limited to these, and can be formed in any shape such as an ellipse, a circle, and a rhombus.
[0011]
Moreover, the dimension of this invention sheet | seat 1 is also arbitrary and is determined by making it correspond to the dimension of the base 11 of the cleaning tool 10. FIG. As the cleaning tool sheet 1 used for cleaning the floor or the like at home, a sheet having dimensions of 300 mm in width and 200 mm in length is usually used. This invention sheet is not limited to what is applied to a household cleaning tool, It is applicable also to the large sized cleaning tool used in a factory, an office, a hospital, a store, etc. In this case, the cleaning tool sheet 1 having a size larger than the above size is formed.
[0012]
As described above, the sheet 1 of the present invention is configured by providing the nonwoven fabric sheet 2 with a large number of through cuts 3. However, the cut 3 penetrating here means that the cut 3 penetrates in the thickness direction of the nonwoven fabric sheet 2. Even when a plurality of nonwoven fabric sheets 2 are polymerized, the cuts 3 are provided so as to penetrate each layer of the multilayer nonwoven fabric sheet. In order to provide the cut 3, a cutting line is formed in the nonwoven fabric sheet 2. In this case, in a state where the cleaning tool sheet 1 is attached to the cleaning tool 10, the cutting line is not parallel to the cleaning direction, that is, cleaning is performed. A cutting line is formed in a direction non-parallel to the direction. For example, in FIGS. 1 and 2, the cut 3 is formed so that the direction of the cutting line is perpendicular to the cleaning direction. By providing the cuts 3 at predetermined intervals in the vertical direction, a single cut line 4 is formed, and a plurality of such cut lines 4 are provided in the horizontal direction.
[0013]
As shown in FIGS. 1 and 2, in the cut line 4 in the vicinity of the left and right ends of the sheet, it is preferable that the cuts 3 do not exist at the upper end and the lower end, respectively. With this configuration, when the cleaning tool sheet 1 is attached to the base 11 of the cleaning tool 10, the sheet 1 can be securely held and fixed, and the holding and fixing force is not weakened by the cut 3.
Further, as shown in FIG. 1, the cuts 3 in the cut row 4 in the vicinity of the left and right ends of the sheet may be shorter than the three rows of cuts located inside.
[0014]
The number of the cut lines 3 is only required to be large, and the number of the cut line 4 is 5 in the case of FIGS. 1 and 2, but the size of the nonwoven fabric sheet 2 or the base of the cleaning tool 10 Depending on the size of eleven, the number of rows of cut rows 4 can be provided in an arbitrary number.
[0015]
As shown in FIGS. 1 and 2, the cut 3 is preferably provided so as to be at the same position in the vertical direction. Therefore, it is preferable that the cut 3 is provided so as to be located at the same position in the vertical direction. . Further, the intervals between the cut lines 4 may not be formed at a constant interval as long as they are provided in parallel.
[0016]
In the example shown in FIGS. 1 and 2, the shape of the cut 3 is a straight line, but the shape of the cut 3 is not limited to the straight cut 3. As another example of the cut line 3, as shown in FIG. 3, each cut line 3 has a continuous jagged shape (a), a continuous wave shape (b), or discontinuous semicircles alternately in opposite directions. Various shapes are possible, such as the shape (c) lined up facing.
[0017]
In the above example, the cut 3 having a predetermined length is intermittently provided in the lateral direction, but the cut 3 is provided in a straight line that is continuous in the horizontal direction without being intermittent. May be.
[0018]
When the sheet of the present invention is constituted by polymerizing a plurality of nonwoven fabric sheets 2, a joining portion 6 for joining the nonwoven fabric sheets 2 to each other is provided.
[0019]
In order to provide the joining portion 6, the joining portion 6 is usually joined by heating and melting with the nonwoven fabric 2 sandwiched by a heat seal device, or by using an adhesive. As a joining method by heating and melting, in addition to the heat sealing apparatus, an ultrasonic sealing apparatus that heats and seals by ultrasonic irradiation can also be used. As the adhesive, a hot melt adhesive or the like is used.
[0020]
Although the position where the joint portion 6 is provided is arbitrary, it is preferably provided on the periphery of the sheet 1 as shown in FIG. In the embodiment shown in the figure, the joints 6 are provided at the upper edge 7 and the lower edge 8 of the sheet 1, but the joints 6 may be provided at the left and right edges or at the entire peripheral edge. Good.
Further, as shown in FIG. 2, the joint 6 may be provided along the longitudinal direction of each cut line 4. With such a configuration, it is possible to prevent the cut 3 from being deformed more than necessary during cleaning, and it is possible to further improve the dust / dust capturing ability and the once-trapped dust / dust retaining ability.
The joint portion 6 may be provided at both the peripheral portion of the sheet 1 and the portion along the longitudinal direction of the cut row 4, and the joint portion 6 may be a continuous line, an intermittent line, or It may be a discontinuous point.
[0021]
In manufacturing the sheet of the present invention, an apparatus provided with a hot blade for heat-sealing the nonwoven fabric sheet 2 and a cutting blade for providing a cut 3 in the nonwoven fabric sheet 2 can be used. By using such an apparatus, it is possible to form the joint 6 and the cut 3 at the same time.
[0022]
Although the cleaning tool sheet 1 of the present invention exhibits a sufficient cleaning ability even without a chemical treatment, the cleaning ability may be improved by performing a chemical treatment. As this chemical treatment, it is possible to employ a method in which an oil containing a mineral oil such as liquid paraffin, a silicone oil, or a surfactant such as a nonionic active agent is attached to the surface of the sheet 1 by spraying.
[0023]
The cleaning tool sheet 1 configured as described above is used by being attached to a base 11 of a cleaning tool 10 with a handle 12 as shown in FIG. The cleaning tool sheet 1 is brought into contact with the pedestal 11 of the cleaning tool 10, the attachment portion 9 of the sheet 1 is bent and wound around the upper surface of the pedestal 11, and the four end portions of the sheet attachment portion 9 are locked to the upper surface of the pedestal 11. And install.
[0024]
Since the cleaning tool sheet 1 of the present invention is configured by providing a large number of cuts 3 penetrating the nonwoven fabric sheet 2 as described above, dust / dust is reliably captured by the cuts 3 during cleaning, and the collected dust / Dust enters the gap between the cuts 3 and is securely held in the gap.
[0025]
The cut 3 is deformed flexibly by the frictional force between the sheet 1 and the floor surface during cleaning, and a bowl-shaped uneven rough surface is formed on the surface of the sheet 1. Dust / dust is swept away by the rough surface and captured by the surface of the sheet 1, and the captured dust / dust enters the gap between the cuts 3 and is held in the gap.
[0026]
As the number of cuts 3 formed along the surface of the cleaning tool sheet 1 increases, the trapping property for dust and dust increases. On the other hand, the gap between the cuts 3 is the thickness of the cleaning tool sheet 1. If there are many in the direction, the trapping and retaining properties against dust / dust will be further improved. From this point of view, it is preferable that a plurality of nonwoven fabric sheets 2 are polymerized to form a multilayer nonwoven fabric sheet, and a cut 3 penetrating therethrough is provided.
[0027]
As described above, according to the present invention, relatively large dust / dust can be captured without escaping by the gap between the cuts 3, and the capturing capability is high. In addition, since the dust / dust once captured is reliably held in the gap, it is possible to prevent the dust / dust from being separated after capture.
Further, when a cutting line is made in the nonwoven fabric for forming the cut 3, since the fibers of the nonwoven fabric are raised in the cut 3, fine dust and dust can be reliably captured by the raised portion.
[0028]
【The invention's effect】
The cleaning tool sheet of the present invention is provided with a large number of penetrated cuts in at least one non-woven sheet, so that it has a large capturing ability not only for fine dust / dust but also relatively large dust / dust. It has a great ability to retain dust and dust once it has been captured, and has an excellent cleaning ability.
