Abstract

A wipe is provided that includes a first wiping member bonded to a backing member along valleys, whereby the wiping member includes a plurality of discrete peaks, and an adhesive is provided, in one embodiment, in the valleys and not on the peaks.

Claims

1. A wipe for cleaning a surface comprising:

a working surface including a plurality of raised ridges and a plurality of recessed valleys wherein the valleys continuously extend from a first edge of the working surface to a second edge of the working surface and are separated from one another by the raised ridges and wherein the raised ridges continuously extend from the first edge of the working surface to the second edge of the working surface and are separated from one another by the valleys;

an adhesive at the working surface of each valley, wherein the working surface of each ridge is substantially free of adhesive.

2. The wipe of claim 1, wherein the ridges are generally linear.

3. The wipe of claim 2, wherein the ridges are generally parallel to one another.

4. The wipe of claim 1, wherein the valleys are generally linear.

5. The wipe of claim 1, wherein the valleys are generally parallel to one another.

6. The wipe of claim 1, wherein the wipe is a nonwoven.

7. The wipe of claim 1, further comprising:

a support layer secured to the wipe opposite the working surface.

8. The wipe of claim 7, wherein the support layer is a nonwoven.

9. A wipe for cleaning a surface comprising:

a single, undulating sheet including a backing surface and a working surface, wherein the working surface includes a plurality of linear raised ridges and a plurality of linear recessed valleys wherein the valleys are separated from one another by the raised ridges and wherein the raised ridges are separated from one another by the valleys;

an adhesive at the working surface of each valley, wherein the working surface of each ridge is substantially free of adhesive;

a support layer secured to the backing surface.

10. The wipe of claim 9, wherein the valleys continuously extend from a first edge of the sheet to a second edge of the sheet and wherein the raised ridges continuously extend from the first edge of the sheet to the second edge of the sheet.
