Abstract

The invention provides a cleaning sheet that is excellent in capturing dust and dirt. The cleaning sheet according to the invention includes a base material sheet (2) and a cleaning surface forming sheet (3) that is bonded to the base material sheet (2). A slacked section (5) is formed in the cleaning surface forming sheet (2) between the bonding sections (6, 6) where the base material sheet (2) and the cleaning surface forming sheet (3) are bonded to each other, and a plurality of cuts (7) for capturing dust and dirt are formed at the slacked section (5).

Claims

1. A cleaning sheet comprising:

a base material sheet;

a cleaning surface forming sheet being bonded to a surface of the base material sheet;

a plurality of bonding sections being defined where the base material sheet and the cleaning surface forming sheet are bonded to each other, and being formed in a direction parallel to end edge portions of the base material sheet;

a plurality of slacked sections being arranged to the cleaning surface forming sheet between the bonding sections where the base material sheet and the cleaning surface forming sheet are bonded to each other; and

a plurality of cut portions for capturing dust and dirt being formed at each of the plurality of slacked sections, wherein

flat sections including a plurality of opening holes are formed between the plurality of slacked sections, and

each of the flat sections is bonded to the base material sheet by an adhesive to form the bonding sections.

2. The cleaning sheet according to claim 1,

wherein an adhesive layer is formed between the plurality of flat sections and the base material sheet, and

the adhesive layer is exposed to the outside through the opening holes of the plurality of flat sections.

3. The cleaning sheet according to claim 1,

wherein another cleaning surface forming sheet is bonded to another surface of the base material sheet.

4. The cleaning sheet according to claim 3,

wherein an adhesive layer is formed between the plurality of flat sections and the base material sheet, and

the adhesive layer is exposed to the outside through the opening holes of the plurality of flat sections.

5. The cleaning sheet according to claim 1,

wherein each of the base material sheet and the cleaning surface forming sheet is formed of nonwoven fabric.

6. The cleaning sheet according to claim 5,

wherein an adhesive layer is formed between the plurality of flat sections and the base material sheet, and

the adhesive layer is exposed to the outside through the opening holes of the plurality of flat sections.

7. The cleaning sheet according to claim 1,

wherein the plurality of cut portions is formed by slits provided on the cleaning surface forming sheet.

8. The cleaning sheet according to claim 7,

wherein an adhesive layer is formed between the plurality of flat sections and the base material sheet, and

the adhesive layer is exposed to the outside through the opening holes of the plurality of flat sections.

9. The cleaning sheet according to claim 1,

wherein the plurality of cut portions is formed by through holes provided on the cleaning surface forming sheet.

10. The cleaning sheet according to claim 9,

wherein an adhesive layer is formed between the plurality of flat sections and the base material sheet, and

the adhesive layer is exposed to the outside through the opening holes of the plurality of flat sections.
