Description

  The present invention relates to a disposable wiping sheet that is useful as a cleaning towel sheet and a kitchen towel sheet and has an excellent wiping function.

  As a disposable wiping sheet used as a cleaning towel sheet or a kitchen towel sheet for kitchens, paper or non-woven fabric sheets are widely used. These wipes have a substantially flat wipe sheet surface with a fine mesh or fine crepe, or the embossing roll allows the wipe sheet to have substantially the same unevenness on both sides. Also known is the formation of structural embossments. (For example, a base paper for toweling with embossing disclosed in JP-A No. 2004-267237)

  By the way, when wiping off dirt on the floor surface or around the range as a wiping sheet for cleaning, since the floor surface to be wiped has a lot of small and large dust such as fine dust and relatively large dust, this wiping sheet Is required to have a function of capturing and wiping off these large and small dusts. In addition, when wiping off oily persistent dirt adhering to the periphery of the range or the like, a so-called rough wiping action that increases the wiping frictional force of the wiping sheet is also required.

  On the other hand, when wiping off dirt such as tableware as a wiping sheet for kitchens, in addition to the general function of wiping off moisture adhering to tableware after washing with water, persistent stains such as eating residue firmly attached to tableware are removed. A so-called rough wiping action in which the wiping friction force of the wiping sheet is removed by wiping in advance before washing with water is also required.

  However, various conventional paper and non-woven cloth wiping sheets having a substantially flat wiping sheet surface are known to have improved water absorption, which effectively wipes off moisture adhering to the object to be wiped. There is no known one that has improved the wiping friction force of the wiping sheet so that the filth and scum stubbornly adhered to the wiping target can be wiped off. In addition, conventional paper and non-woven cloth wipe sheets that have a substantially flat wipe sheet surface do not have enough capacity to trap various types of dust on the wipe sheet surface, and can be wiped off reliably. There wasn't.

In addition, the wiping sheet with a concavo-convex structure by embossing a flat sheet seems to be able to expect some wiping frictional force and dust trapping function compared to a wiping sheet with a flat sheet surface, When it is suppressed, the suppressed uneven embossed part is leveled as if it was extended as a whole, and the unevenness is almost disappeared, and simply embossing is not effective and solves the above problems It was impossible.
JP 2004-267237 A

  The wiping sheet according to the present invention was developed in view of such circumstances, and as a solution to that problem, a cleaning towel sheet having a wiping sheet surface having a sheet structure with improved wiping frictional force and dust capturing function And to provide a disposable wiping sheet useful as a kitchen towel sheet.

  In order to solve the above-described problems, the present invention provides a flat sheet such as paper or nonwoven fabric having a substantially flat sheet surface, a convex portion on the front side corresponds to a concave portion on the back side, and a concave portion on the front side corresponds to the rear side. Each of the concave portions on the surface side of the embossed sheet is provided with an embossed sheet such as paper or nonwoven fabric having a concave-convex structure corresponding to the convex portions of the paper, and alternately forming these convex portions and concave portions on the front surface side and the back surface side. And the embossed sheet forming one surface side of the laminated sheet with respect to the sheet surface of the flat sheet. Each of the hollow convex portions on the surface side of the embossed sheet fixed in position by the adhesive portion is crushed and surrounded by the convex edge portion and the convex edge portion forming a boundary with the concave portion on the surface side at the position Forms wrinkle-giving projections that are made up of wrinkles Providing wiping sheet, characterized in that was wrinkled sheet.

  In the invention of the wiping sheet, at least one surface side of the wiping sheet having a laminated sheet structure is a sheet with a ridge, and the sheet with the ridge is the position of the embossed sheet fixed at the adhesive portion with respect to the sheet surface of the flat sheet. The hollow convex portions on the front surface side are crushed, and the concave portions on the front surface side (the top portions of the convex portions on the back surface side corresponding to the concave portions on the front surface side are bonded to the sheet surface of the flat sheet. ) And a wrinkle-provided convex portion composed of a wrinkle surrounded by the convex edge portion, so that the convex edge of the wrinkle-provided convex portion of the sheet with wrinkles The wiping frictional force by the collar part surrounded by the part and the convex edge part is strong, and it is possible to effectively wipe off the filth and food waste that are stubbornly adhered to the object to be wiped. Further, the wrinkle imparting convex portion and the concave portion on the surface side are alternately formed, and the concave portion on the surface side is arranged adjacent to and surrounded by the concave portion on the surface side around the wrinkle imparting convex portion. Since the top of each convex part on the back side corresponding to the concave part is bonded to the sheet surface of the flat sheet, it is suppressed even if it is manually suppressed at the time of wiping, unlike a sheet simply embossed. Further, the wrinkle imparting convex portions are not easily leveled as if they are extended as a whole, and the concavo-convex structure of the alternately formed wrinkle imparting convex portions and the concave portions on the surface side is retained and hardly disappears. For this reason, combined with the function of the wrinkle imparting convex portion, the function of capturing dust by the concave and convex portion is high.

  The flat sheet is a sheet having water absorbency such as paper or non-woven fabric, and the top of each convex part on the back side corresponding to each concave part on the front side of the embossed sheet can be partially adhered to the sheet surface of the flat sheet. In addition, a sheet having a substantially flat sheet surface includes a sheet having a minute crepe formed on the sheet surface and a mesh sheet having a large number of minute perforations.

  The embossed sheet is a sheet having water absorbency such as paper and nonwoven fabric, the convex portion on the front side corresponds to the concave portion on the back side, and the concave portion on the front side corresponds to the convex portion on the back side, These convex portions and concave portions are alternately formed on the front surface side and the back surface side, but the convex shape of the front and back of this embossed sheet is a cone or square pyramid with the top of the convex portion as a flat surface. Can be adopted. The shape of the convex portions on the front and back sides of the embossed sheet is not particularly limited, but the top portion of the convex portion on the back surface side to be bonded to the sheet surface of the flat sheet improves adhesion to the sheet surface of the flat sheet. A flat surface is preferable. Moreover, it is preferable that the embossed sheet which becomes a sheet | seat with a ridge has a large plane ratio of the total area of each hollow convex part of the surface side which becomes a wrinkle provision convex part compared with the total area of an adhesion part. The embossed sheet also includes a mesh-like sheet in which a large number of micro-perforations are formed within a range that does not hinder the formation of uneven embossing. The embossed sheet used in the present invention is partially lightly embossed (embossed with a lower height than other embossed) or non-embossed with respect to the entire sheet surface of the embossed sheet as in the invention of Patent Document 1. This does not exclude the embossed sheet on which the region is formed. However, since the light embossed or non-embossed region may not be adhered to the sheet surface of the flat sheet or may be poorly bonded, the region such as light embossed is a small range with respect to the entire sheet surface of the embossed sheet. It is necessary to.

  Adhesion between the embossed sheet and the flat sheet is an adhesive that partially adheres to the sheet surface of the flat sheet via an adhesive applied to the top of each convex part on the back side corresponding to the concave part on the front side of the embossed sheet. A heat welding sheet is interposed between the flat sheet and the embossed sheet, and both the top of each convex part on the back side corresponding to each concave part on the front side of the embossed sheet and the sheet surface of the flat sheet are both It is possible to adopt a thermal bonding method in which partial bonding is performed by thermal bonding using the thermal welding sheet interposed between the sheets. In the case of partial adhesion via the heat welding sheet, the wiping sheet has a three-layer structure of a sheet with a flange and a flat sheet with the heat welding sheet interposed therebetween. As the heat welding sheet, a thin sheet, a thermoplastic resin film sheet, a paper or a nonwoven fabric sheet mixed with thermoplastic fibers, and the like can be adopted. The heat welding sheet interposed between the two sheets is preferably a mesh-like sheet in which a large number of micro-perforations are formed. Also, it is possible to adopt a bonding method in which one or both of the flat sheet and the embossed sheet are heat-weldable sheets and the sheets are partially bonded by heat bonding of the heat-weldable sheets. As the heat-weldable sheet, a paper or nonwoven fabric sheet in which thermoplastic fibers are mixed can be employed.

  The wiping sheet according to the present invention has at least one side of the wiping sheet as a sheet with a ridge, and the sheet with the ridge is formed by a convex edge portion of the ridge-giving convex portion and a ridge portion surrounded by the convex edge portion. The wiping frictional force is strong, and it is possible to effectively wipe off filth and food waste that are stubbornly adhered to the wiping target. Further, the wrinkle imparting convex portion and the concave portion on the surface side are alternately formed, and the concave portion on the surface side is arranged adjacent to and surrounded by the concave portion on the surface side around the wrinkle imparting convex portion. Since the top of each convex part on the back side corresponding to the concave part is bonded to the sheet surface of the flat sheet, it is suppressed even if it is manually suppressed at the time of wiping, unlike a sheet simply embossed. Since the wrinkle-provided convex portion is not easily leveled as extended as a whole, and the uneven structure of the alternately formed wrinkle-provided convex portion and the concave portion on the surface side is held and difficult to disappear, the function of the wrinkle-provided convex portion Combined with this, it has a high dust trapping function by this uneven part. The wiping sheet according to the present invention is excellent in wiping friction force and dust capturing function as described above, and is useful as a cleaning towel sheet or a kitchen towel sheet.

  Further, the wiping sheet according to the present invention in which one side is a flat sheet and the other side is a flat sheet having a substantially flat sheet surface is roughly wiped on the side having a strong wiping frictional sheet, By performing finish wiping on the side, dirt to be wiped off can be effectively wiped off, which is useful as a cleaning towel sheet or a kitchen towel sheet.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a schematic plan view of the wiping sheet of the present invention, FIG. 2 is a longitudinal end view taken along line AA in FIG. 1, and FIG. 3 is a longitudinal end view taken along line AA in FIG. is there.

The top portion is a laminated sheet (S1) partially bonded to the sheet surface of the flat sheet 2 via an adhesive 4, and the embossed sheet 3 forming one side of the laminated sheet is placed on the sheet surface of the flat sheet 2 The emboss which is fixed in position by the adhesive part 4 Each of the hollow convex portions 3a on the surface side of the sheet 3 is crushed to form a convex edge portion 5a that forms a boundary with the concave portion on the surface side at the position, and a flange portion 5b surrounded by the convex edge portion 5a. This is a sheet 6 with ridges on which the ridge imparting convex portions 5 are formed.

  The partial adhesion between the embossed sheet 3 and the flat sheet 2 was applied to the top of each convex portion 3c on the back surface side corresponding to each concave portion 3b on the front surface side of the embossed sheet 3 by using the uneven height difference. This is done by adhering the top to the sheet surface of the flat sheet 2 via an adhesive 4. The tops of the convex portions 3 c on the back side of the embossed sheet 3 are flat surfaces as shown in FIG. 2 in order to improve the adhesiveness with the sheet surface of the flat sheet 2.

  The wrinkle imparting convex portion 5 of the sheet with ridges 6 is formed on the front side concave portions 3b alternately formed with the wrinkle imparting convex portions 5 (the top portions of the respective convex portions 3c on the back surface side corresponding to the concave portions 3b on the front side). Is partially adhered to the sheet surface of the flat sheet 2.) The wiping frictional force by the convex edge portion 5a that forms a boundary between the flat sheet 2 and the flange portion 5b surrounded by the convex edge portion 5a is strong, It is possible to effectively wipe off filth and food waste that have been stubbornly adhered to the object to be wiped off. Further, the wrinkle-giving convex portions 5 and the surface-side concave portions 3b are alternately formed, and the surface-side concave portions 3b are adjacently arranged around the wrinkle-giving convex portions 5 and are surrounded by the surface-side concave portions 3b. Since the top part of each convex part 3c on the back surface side corresponding to the concave part 3b on the front surface side is a structure adhered to the sheet surface of the flat sheet 2, unlike a sheet simply embossed, Even if suppressed by hand, the suppressed wrinkle-provided convex portions 5 are not easily leveled as if they were extended as a whole, and the uneven structure between the alternately formed wrinkle-provided convex portions 5 and the concave portions 3b on the surface side is maintained and disappears. Hateful. For this reason, in combination with the function of the wrinkle imparting convex portion 5, the function of capturing dust by the concave and convex portion is high.

  The flat sheet 2 is a sheet having a water absorption property such as paper or nonwoven fabric, and the top surface of each convex portion 3c on the back side corresponding to the concave portion 3b on the front side of the embossed sheet (preferably flat) If it has a sheet surface that is substantially flat enough to bond the top part with a surface), a sheet with a minute crepe formed on the sheet surface or a mesh sheet with many micro-perforations can be selected. It is.

  The embossed sheet 3 is a sheet having water absorbency such as paper or non-woven fabric. The convex portion 3a on the front side corresponds to the concave portion 3d on the back side, and the concave portion 3b on the front side corresponds to the convex portion 3c on the back side. It has a structure, and these convex portions and concave portions are alternately and regularly formed on the front surface side and the back surface side. The shapes of the convex portions 3a and 3c on the front and back sides of the embossed sheet 3 are as shown in the figure. It is possible to adopt a conical shape in which the tops of the convex portions 3a and 3c are flat surfaces, or a quadrangular pyramid shape in which the top portions of the convex portions 3a and 3c are flat surfaces. The shape is not limited to these shapes. However, as described above, the top of the convex portion 3c on the back surface side that is bonded to the sheet surface of the flat sheet 2 is preferably a flat surface in order to improve the adhesion to the sheet surface. Further, the embossed sheet 3 which is the sheet 6 with the ridge is wider than the total area of the adhesive portion 4 by increasing the plane ratio of the total area of the hollow convex portions 3 a on the surface side which are the ridge-applying convex portions 5. It is formed.

  The wiping sheet 1 of FIG. 1 shown in the longitudinal end view of FIG. 3 interposes a heat welding sheet 7 between the flat sheet 2 and the embossed sheet 3 and corresponds to each concave portion 3 b on the surface side of the embossed sheet 3. A bonding method is adopted in which the flat tops of the respective convex portions 3 c on the back surface side and the sheet surface of the flat sheet 2 are partially bonded (bonded portions 4) by thermal bonding of the heat welding sheet 7. The wiping sheet 1 partially bonded via the heat welding sheet 7 has a three-layer structure of an embossed sheet 3 (sheet 6 with ridges) and a flat sheet 2 with the heat welding sheet 7 interposed therebetween. As the heat-welding sheet 7, a thin sheet material that is thermally bonded by heating, such as a thermoplastic resin film sheet, a paper mixed with thermoplastic fibers, or a sheet of nonwoven fabric, can be appropriately employed. In addition, since the other structure of the wiping sheet | seat 1 shown in FIG. 3 is substantially the same as the structure of the wiping sheet | seat 1 shown in above-described FIG. 1, FIG. 2, the description is abbreviate | omitted.

It can be adopted. As the heat-weldable sheet, a paper or nonwoven fabric sheet in which thermoplastic fibers are mixed can be employed.

  Next, the manufacturing method of the wiping sheet of this invention is demonstrated with reference to FIG. 4, FIG. In the following description of the manufacturing method, each sheet such as an embossed sheet, a flat sheet, and a laminated sheet is a long continuous sheet.

  FIG. 4 shows a manufacturing method in the case where the flat sheet 2 and the embossed sheet 3 (sheet 6 with the flange) are bonded together with an adhesive. In the figure, reference numerals 10a and 10b denote embossing rollers, 11 denotes an adhesive application roller, 12 denotes an adhesion pressing roller, 13a and 13b denote crushing rollers, and 14 denotes a winding roller. The embossed continuous sheet S is passed through the embossing rollers 10a and 10b, and the convex portion 3a on the front side corresponds to the concave portion 3d on the back surface side, and the concave portion 3b on the front surface side corresponds to the convex portion 3c on the back side. And embossing is performed on the embossed sheet 3 in which the convex portions and the concave portions are alternately and regularly formed on the front surface side and the back surface side. The embossed embossed sheet 3 is coated with the adhesive 4 on the flat top of each convex portion on the back side of the embossed sheet 3 by the adhesive application roller 11 during the feeding process, and the adhesive 4 is partially applied. The embossed sheet 3 and the supplied flat sheet 2 are overlapped between one embossing roller 10a and the adhesive pressing roller 12 with the back side of the embossed sheet being inward, It is partially bonded via an adhesive 4 applied to the flat top of each convex portion, and a laminated sheet S1 of the embossed sheet 3 and the flat sheet 2 is obtained. The laminated sheet S1 is sent to the crushing rollers 13a and 13b, and the laminated sheet S1 that has passed between the crushing rollers 13a and 13b is formed by replacing the embossed sheet 3 forming one surface side of the laminated sheet S1 with the flat sheet 2. A convex edge that crushes each of the hollow convex portions 3a on the surface side of the embossed sheet 3 fixed at the adhesive portion 4 with respect to the sheet surface to form a boundary with the concave portion 3b on the surface side at the position A laminated sheet (wiping sheet 1) formed on a sheet 6 having a ridge, which is formed with a ridge imparting convex part 5 composed of a part 5a and a ridge part 5b surrounded by the convex edge part 5a. ) Is wound up into a roll by the winding roller 14.

  FIG. 5 shows a manufacturing method in the case where the flat sheet 2 and the embossed sheet 3 (the sheet 6 with the flange) are bonded via the heat welding sheet 7. In the figure, reference numerals 10a and 10b denote embossing rollers, 12 denotes an adhesion pressing roller, 13a and 13b denote crushing rollers, and 14 denotes a winding roller. The pressing roller 12 for adhesion and the embossing roller 10a in contact with the roller 12 have both rollers or one of the rollers as a heating roller. The embossed continuous sheet S is passed through the embossing rollers 10a and 10b, and the convex portion 3a on the front side corresponds to the concave portion 3d on the back side and the concave portion 3b on the front side corresponds to the convex portion 3c on the back side. And embossing is performed on the embossed sheet 3 in which the convex portions and the concave portions are alternately and regularly formed on the front surface side and the back surface side. The embossed embossed sheet 3 is bonded to one embossed roller 10a in the state in which the embossed sheet 3 and the supplied flat sheet 2 sandwich the supplied heat welding sheet 7 between them. It is overlapped between the pressing rollers 12 and heated, and the flat top portion of each convex portion 3c on the back side of the embossed sheet 3 and the sheet surface of the flat sheet 2 are partially heat-melt bonded via the heat-bonding sheet 7. Then, a laminated sheet S2 of the embossed sheet 3 and the flat sheet 2 partially bonded with the heat welding sheet 7 interposed therebetween is obtained. Thereafter, the process until the laminated sheet S2 is wound into a roll shape by the winding roller 14 is substantially the same as the manufacturing method described in FIG. That is, the laminated sheet S2 is sent to the crushing rollers 13a and 13b, and the laminated sheet S2 that has passed between the crushing rollers 13a and 13b has the embossed sheet 3 that forms one surface side of the laminated sheet S2 as the plane. Convex shape which forms a boundary with the concave portion 3b on the surface side by crushing each hollow convex portion 3a on the surface side of the embossed sheet 3 fixed at the adhesive portion with respect to the sheet surface of the sheet 2 Laminated sheet (wiping sheet) formed on a sheet 6 having a ridge, which is formed with a ridge-provided convex part 5 composed of an edge part 5a and a ridge part 5b surrounded by the convex edge part 5a. 1) is wound up in a roll shape by a winding roller 14.

The embossed sheet 3 is formed on the sheet 6 with the flange by forming the part 5. By passing between the crushing rollers 13a and 13b in this way, each hollow convex portion 3a on the surface side can be strongly crushed, and the convex edge portion 5a that forms a boundary with the concave portion 3b on the surface side at the position, It is possible to reliably form the wrinkle imparting convex portion 5 composed of the flange portion 5b surrounded by the convex edge portion 5a. However, even if it does not pass between the crushing rollers 13a and 13b, if the laminated sheets S1 and S2 of the partially bonded embossed sheet 3 and the flat sheet 2 are wound up tightly by the take-up roller 14, it is tightly wound up. Each of the hollow convex portions 3a on the surface side of the embossed sheet 3 is crushed by the winding pressure of the outer laminated sheets S1 and S2, and the convex edge portion 5a that forms a boundary with the concave portion 3b on the surface side at the position, A large number of wrinkle imparting convex portions 5 composed of the flange portions 5 b surrounded by the convex edge portions 5 a can be formed, and the embossed sheet 3 can be used as the sheet 6 with the wrinkles. Thus, even if the laminated sheets S1 and S2 are wound up tightly by the take-up roller 14, the embossed sheet 3 is partially bonded (adhered portion 4) to the flat sheet 2, so that only the embossed sheet 3 is wound. Unlike take-up, the uneven embossed portion is leveled as if it extends in the winding direction, and there is no harmful effect that the unevenness disappears. Moreover, if the embossing sheet 3 side is inward as shown in the drawing and the winding roller 14 is wound up tightly, the embossing sheet 3 is hollowed on the surface side of the embossing sheet 3 by the winding pressure of the flat sheet 2 arranged on the outer side. Each of the convex portions 3a is crushed more strongly, and the embossed sheet 3 can be made into the sheet 6 with a hook more reliably in the winding process.
