Abstract

OBJECT: To realize a wiping sheet with sufficient flexibility, high adhesion strength, easy attachment on concavo-convex surface, good adhesiveness and durability.

CONSTITUTION: A wiping sheet 4 wherein a microfiber cloth having a dirt wiping effect is laminated on one side of a resin film of 20 μm or less in thickness, and a polymer sheet having an adhesive effect due to suction function of fine bubbles is laminated on the other side.

Claims

1. A wiping sheet wherein a microfiber cloth having a dirt wiping effect is laminated on one side of a resin film of 20 μ

m or less in thickness, and a polymer sheet having an adhesive effect due to suction function of fine bubbles is laminated on the other side.

2. The wiping sheet of claim 1, wherein said polymer sheet is an acryl based polymer sheet.

3. The wiping sheet of claim 1, wherein said microfiber cloth is a non-woven cloth.

4. The wiping sheet of claim 2, wherein said microfiber cloth is a non-woven cloth.
