Abstract

The present invention relates to a low oil and basis weight, apertured dusting wipe exhibiting improved particulate pick up performance.

Claims

1. An apertured dusting wipe, comprising a nonwoven fabric having a plurality of apertures, wherein the fabric has a basis weight less than about 60 gsm, at least about 125 apertures per square inch of fabric, and mineral oil in an amount of about 1 to about 15% by weight, wherein said apertured dusting wipe has a pick-up % of at least 8%.

2. An apertured dusting wipe as in claim 1, wherein the nonwoven fabric is comprised of staple length fibers.

3. An apertured dusting wipe as in claim 1, wherein the nonwoven fabric is a single layer.

4. An apertured dusting wipe as in claim 1, wherein the nonwoven fabric is an adhesive bonded fabric.

5. An apertured dusting wipe as in claim 4, wherein the adhesive comprises a latex binder topically applied to at least one surface of the fabric in a total add-on amount, on a solids basis, ranging from about 3 to about 15 g/m².

6. An apertured dusting wipe as in claim 5, wherein the adhesive is applied in a discontinuous pattern.

7. An apertured dusting wipe as in claim 5, wherein the adhesive is applied in a continuous pattern.

8. An apertured dusting wipe as in claim 2, wherein the nonwoven fabric is chosen from the group consisting of natural fiber, synthetic fiber, and combinations thereof.

9. An apertured dusting wipe as in claim 8, wherein the natural fiber is a cellulosic fiber selected from the group consisting of viscose rayon, cotton, wood pulp, flax, hemp, and combinations thereof.

10. An apertured dusting wipe as in claim 8, wherein the synthetic fiber is selected from the group consisting of cellulosic, polyolefins, polyesters, polyamides, and combinations thereof.

11. An apertured dusting wipe as in claim 9, wherein the nonwoven fabric is viscose rayon.

12. An apertured dusting wipe as in claim 1, wherein the apertures are slit-like.

13. An apertured dusting wipe as in claim 1, wherein the wipe contains about 7% to about 13% by weight mineral oil.

14. An apertured dusting wipe, comprising a cellulosic nonwoven fabric having a plurality of apertures and an adhesive topically applied in a discontinuous pattern, wherein the fabric has a basis weight less than about 60 gsm, at least about 125 apertures per square inch of fabric, and mineral oil in an amount of about 1 to about 15% by weight, wherein said apertured dusting wipe has a pick-up % of at least 10%.

15. A method for removing particulate detritus from a surface, comprising contacting the surface with an apertured dusting wipe comprising a nonwoven fabric having a plurality of apertures, wherein the fabric has a basis weight less than about 60 gsm, at least about 125 apertures per square inch of fabric, and mineral oil in an amount of about 1 to about 15% by weight, wherein said apertured dusting wipe has a pick-up % of at least 8%.

16. The method of claim 15 wherein surface comprises a hard substantially flat surface.

17. The method of claim 15 wherein the nonwoven fabric comprises adhesive binder.

18. The method of claim 17, wherein said adhesive binder comprises a topically applied latex binder in a total add-on amount, on a solids basis, ranging from about 3 to about 15 g/m².

19. The method of claim 17 wherein the adhesive binder is present in a discontinuous pattern in the fabric.

20. The method of claim 15 wherein the nonwoven fabric comprises about 7 to about 13 weight percent mineral oil.
