Description

The present invention relates to a wiping tool such as a flooring wiper and a sheet used therein.

Flooring wipers that include a handle, a rectangular plate-shaped head attached to the lower end of the handle, and a non-woven fabric sheet detachably attached to the head are widely used. A normal flooring wiper uses a non-woven fabric sheet whose left-right width is equal to the long side of the lower surface of the head and whose length is about twice the short side of the lower surface of the head. Then, one non-woven fabric sheet is attached to the head by applying the central portion in the length direction to the lower surface of the head and engaging the end portion in the length direction into the engagement slit on the upper surface of the head, and wipes and cleans the flooring. When a considerable amount of dirt such as dust, dirt, and hair adheres to the non-woven fabric sheet, remove it from the head and reattach (replace) a new non-woven fabric sheet to the head.

However, it is troublesome to attach / detach the non-woven fabric sheet to / from the head each time it is used. Further, since the non-woven fabric sheet has a large left-right width and length, there is a problem that dirt that has fallen off from the non-woven fabric sheet easily falls out of the trash can when it is removed from the head on the trash can.

Therefore, conventionally, it has been proposed to use a rectangular non-woven fabric sheet having a size close to the lower surface of the head, stack a plurality of non-woven fabric sheets so that they can be peeled off, and attach the laminated non-woven fabric sheet to the head. .. The rolling cloth is wiped and cleaned with the bottom non-woven fabric sheet, and when the non-woven fabric sheet becomes dirty, it is peeled off by hand, and the non-woven fabric sheet on it is exposed to the bottom so that it can be used.

For example, in Patent Document 1, an adhesive is applied to the front surface of a sheet such as a non-woven fabric, an adhesive is applied to the back surface, a part is made without an adhesive, and an arbitrary number of sheets is laminated. A dust removal sheet is listed. However, it is difficult to adjust the joint strength of the adhesive joint so that it cannot be easily peeled off during wiping and can be easily peeled off when it becomes dirty. In addition, there is a concern that the working environment may deteriorate and the environment may be polluted by the adhesive.

Patent Document 2 describes a non-woven fabric laminate formed by joining upper and lower non-woven fabric sheets by entwining fibers with a needle punch. However, it is also difficult to adjust the bonding strength described above for bonding by needle punching.
Further, Patent Document 2 also describes a non-woven fabric laminate formed by bonding the upper and lower non-woven fabric sheets by heating and melting one surface of the non-woven fabric sheet and superimposing and pressure-welding the other surface of adjacent non-woven fabric sheets. Has been done. However, since the fibers on the surface of the non-woven fabric sheet are melted into a non-fibrous form and then cured over one surface "whole", the flexibility of the fibers is impaired and the texture is deteriorated.

In Patent Document 3, a non-woven fabric sheet is formed by squeezing a stepped portion of an overlapping edge of a non-woven fabric sheet to form an uneven pattern, and the fibers of one sheet are pressed between the fibers of the other sheet at a processing pressure to join them. The laminate is described. However, the feasibility of joining by such drawing is questionable.

In Patent Document 4, a cleaning sheet (which includes a base sheet and a fiber aggregate bonded to the lower surface thereof) is laminated by adhering both ends of the upper and lower base sheets in the longitudinal direction with an adhesive member. The sheet is listed. However, it is difficult to carry out because there is only a description of "adhesive member" and no specific description of the material or the like.

[Example 1]
The laminated sheet 1 of the first embodiment shown in FIGS. 1 to 4 is
A plurality of (for example, 5) rectangular non-woven fabric sheets 2 stacked one above the other,
A plurality of dispersed and arranged hole-shaped heat-welded portions 3 which are joined to each other so as to be peelable between the non-woven fabric sheets 2.
It is composed of one fluffed fiber sheet 4 mounted on the laminated sheet 1 and having more fluff 5 on the upper surface than the non-woven fabric sheet 2.

The non-woven fabric sheet 2 has a corrugated portion 6 added to both short edges of a rectangle having a width of 260 mm and a length of 100 mm, and the maximum lateral width between the corrugated portion 6 and the corrugated portion 6 is 265 mm. As shown in FIG. 4C, since the corrugated portions 6 of the vertically adjacent nonwoven fabric sheets 2 are out of phase, the bottom nonwoven fabric sheet 2 can be easily turned over with respect to the nonwoven fabric sheet 2 above it. The constituent fibers of the non-woven fabric sheet 2 are thermoplastic resin fibers.

As shown in FIG. 1 (c), the hole-shaped heat-welded portion 3 exists as a tubular wall constituting the hole, and a part of the thermoplastic resin fibers constituting the non-woven fabric sheet 2 is melted and solidified. It is a thing. The inner diameter of the hole is 2 mm. Fifteen heat-welded portions 3 are evenly distributed in the plane of the non-woven fabric sheet 2.

The fluffy fiber sheet 4 forms a part of the sheet mounting structure 13, and has a rectangular shape having the same size as the non-woven fabric sheet 2. The fluffy fiber sheet 4 is formed by needle punching a non-woven fabric (which may be the same as or different from the non-woven fabric sheet 2), and some of the fibers are pulled out by the needle punching to bring out the fibers on the upper surface. There are more fluffs 5 than the non-woven fabric sheet 2.

A resin sheet 7 covering the fluff on the lower surface is laminated on the lower surface of the fluffing fiber sheet 4. The resin sheet 7 is made of a thermoplastic resin. However, this resin sheet 7 may be omitted.

The constituent fibers of the fluffy fiber sheet 4 are thermoplastic resin fibers. A part of the thermoplastic resin fiber and a part of the thermoplastic resin of the resin sheet 7 are melted and solidified, and are continuous with the heat-welded portion 3, so that the fluffy fiber sheet 4 is a laminated sheet 1 ( It is attached to the top non-woven fabric sheet 2).

The laminated sheet 1 configured as described above can be efficiently manufactured, for example, as follows.
(1) As shown in FIGS. 2A and 2B, a plurality of non-woven fabric sheets 2 unwound from the raw fabric and one fluffy fiber sheet 4 are fed in an overlapping manner.
(2) Punch out the wave portion 6 on the short edge. Punching has a high degree of freedom in shape.
(3) As shown in FIGS. 2 (a) and 2 (c), the adjacent non-woven fabric sheets 2 are opened so as to be out of phase with the corrugated portion 6, and then re-stacked.
(4) As shown in FIGS. 2A and 2D, the heated needle-shaped heat cutter 8 is pierced into the non-woven fabric sheet 2 and the fluffy fiber sheet 4 to melt the thermoplastic resin fibers around the heat cutter 8. By adjusting the degree of melting by adjusting the heating temperature and the heating time, it is possible to adjust the bonding strength such that the non-woven fabric sheet 2 is "joined so that it cannot be easily peeled off when wiped and cleaned, and can be easily peeled off when it becomes dirty". After melting, the heat cutter 8 is pulled out, and the melted thermoplastic resin is solidified to form a heat-welded portion 3.
(5) The laminated sheet 1 is completed by punching out each predetermined length to form a long edge.

The laminated sheet 1 configured as described above is used for a wiping cleaning tool, for example, the flooring wiper 10 shown in FIGS. 3 and 4. The flooring wiper 10 includes the laminated sheet 1, the handle 11, a rectangular plate-shaped head 12 attached to the lower end of the handle 11, and a sheet mounting structure 13 for detachably attaching the laminated sheet 1 to the head 12. Consists of.

The head 12 has a rectangular plate shape having a width of 250 mm and a length of 100 mm. That is, the non-woven fabric sheet 2 has a left-right width slightly larger than that of the head 12, and has the same length as the head 12.

The seat attachment structure 13 includes the fluffy fiber sheet 4 and a hook-and-loop fastener 14 provided with a hook 16 detachably attached to the head 12. As shown in FIG. 3A, the hook-and-loop fastener 14 extends from a rectangular substrate 15 having substantially the same size as the lower surface of the head 12, a plurality of hooks 16 provided on the lower surface of the substrate 15, and the substrate 15. It is composed of a mounting band 17. As shown in FIG. 3B, the surface fastener 14 is attached to the head 12 by applying the substrate 15 to the lower surface of the head 12 and fixing the mounting band 17 at the upper surface of the head 12 (in the illustrated example, the surface fastener is used). be able to.

Then, as shown in FIG. 4, when the fluffy fiber sheet 4 of the laminated sheet 1 is pressed against the hook 16 of the hook-and-loop fastener 14, the fluff 5 of the fluffy fiber sheet 4 becomes a large number of hooks (instead of the loop side of the hook-and-loop fastener). Since it is locked to 16, the laminated sheet 1 can be easily and surely attached to the head 12 so as not to come off for wiping.

The laminated sheet 1 and the flooring wiper 10 configured as described above are used as follows.
(A) Wipe and clean the rolling with the non-woven fabric sheet 2 which is the lowest in sequence. At this time, the bottom non-woven fabric sheet 2 does not peel off from the non-woven fabric sheet 2 above it due to the joining by the plurality of heat-welded portions 3 dispersedly arranged.
(B) When the bottom non-woven fabric sheet 2 becomes dirty, the bottom non-woven fabric sheet 2 is manually peeled off from the non-woven fabric sheet 2 above it, as shown by a chain line in FIGS. 4 (b) and 4 (c). At this time, since the portion of the heat-welded portion 3 surrounded by an ellipse in FIG. 4C is stress-concentrated and fractured, the bottom nonwoven fabric sheet 2 can be smoothly peeled off. Further, since the non-woven fabric sheet 2 is shorter than the conventional non-woven fabric sheet 2, when the non-woven fabric sheet 2 is peeled off on the trash can, the dirt that has fallen off from the non-woven fabric sheet 2 is unlikely to fall out of the trash can.
(C) When the bottom non-woven fabric sheet 2 is peeled off, the non-woven fabric sheet 2 on the bottom becomes the non-woven fabric sheet 2 exposed at the bottom in order, and can be used immediately. That is, it is not necessary to reattach the non-woven fabric sheet to the head as in the conventional case.
