Abstract

Claims (18)

1. An apertured dusting wipe, comprising an apertured nonwoven fabric having a plurality of apertures wherein the apertures are holes through a nonwoven fibrous web defining wipe hole areas, wherein the holes are free of fibers and which are defined between interconnected fiber groupings or land areas of the nonwoven fabric, wherein the nonwoven fabric has a basis weight less than about 60 gsm, and mineral oil in an amount of about 1 to about 15% by weight, and wherein the nonwoven fabric is an adhesive bonded fabric comprising adhesive applied to the nonwoven fabric wherein the adhesive comprises a latex binder topically applied to at least one surface of the nonwoven fabric in a total add-on amount, on a solids basis, ranging from about 1 to about 25 g/m 2 , with disruption of fibers at the surface of the apertured nonwoven fabric proximate sites where the adhesive binder is deposited upon the fabric surface, and said wipe having a ratio of total fabric land area to total hole area of from about 1 to about 9, and wherein said apertured dusting wipe is a single layer nonwoven fabric construction having 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 latex binder is topically applied to at least one surface of the nonwoven fabric in a total add-on amount, on a solids basis, ranging from about 3 to about 15 g/m 2 .

4. An apertured dusting wipe as in claim 3 , wherein the adhesive is applied in a continuous pattern.

5. An apertured dusting wipe as in claim 2 , wherein the staple length fibers are selected from the group consisting of natural fibers, synthetic fibers, and combinations thereof.

6. An apertured dusting wipe as in claim 5 , wherein the staple length fibers are fibers selected from the group consisting of cellulosic, polyolefins, polyesters, polyamides, and combinations thereof.

7. An apertured dusting wipe as in claim 2 , wherein the staple length fibers comprise viscose rayon staple fibers.

8. An apertured dusting wipe as in claim 1 , wherein the apertures have a shape selected from oval, circular, square, rectangular, triangle, diamond, star shape, and criss-crossed.

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

10. An apertured dusting wipe as in claim 1 , wherein said nonwoven fabric comprising a cellulosic nonwoven fabric and an adhesive topically applied in a discontinuous pattern, wherein said apertured dusting wipe has a pick-up % of at least 10%.

11. An apertured dusting wipe, comprising an apertured nonwoven fabric having a plurality of apertures wherein the apertures are holes through a nonwoven fibrous web defining wipe hole areas, wherein the holes are free of fibers and which are defined between interconnected fiber groupings or land areas of the nonwoven fabric, wherein the nonwoven fabric has a basis weight less than about 60 gsm, and mineral oil in an amount of about 1 to about 15% by weight, and wherein the nonwoven fabric is an adhesive bonded fabric comprising adhesive applied to the nonwoven fabric wherein the adhesive comprises a latex binder topically applied to at least one surface of the nonwoven fabric in a total add-on amount, on a solids basis, ranging from about 3 to about 15 g/m 2 , with disruption of fibers at the surface of the nonwoven fabric proximate sites where the adhesive binder is deposited upon the fabric surface, and said dusting wipe having a ratio of total fabric land area to total hole area of from about 1 to about 9, wherein said apertured dusting wipe is a single layer nonwoven fabric construction having a pick-up % of at least 10%.

12. An apertured dusting wipe as in claim 11 , wherein the ratio of total fabric land area to total hole area is from about 2.5 to about 7.5.

13. An apertured dusting wipe, comprising an apertured nonwoven fabric having a plurality of apertures wherein the apertures are holes through a nonwoven fibrous web defining wipe hole areas, wherein the holes are free of fibers and which are defined between interconnected fiber groupings or land areas of the nonwoven fabric, wherein the nonwoven fabric has a basis weight less than about 60 gsm, and mineral oil in an amount of about 1 to about 15% by weight, wherein the nonwoven fabric is an adhesive bonded fabric comprising adhesive applied to the nonwoven fabric wherein the adhesive comprises a latex binder topically applied to at least one surface of the nonwoven fabric in a total add-on amount, on a solids basis, ranging from about 3 to about 15 g/m 2 , with disruption of fibers at the surface of the apertured nonwoven fabric proximate sites where the adhesive binder is deposited upon the fabric surface, and said dusting wipe is a single layer nonwoven fabric construction having a ratio of total fabric land area to total hole area of from 1 to 9.

14. An apertured dusting wipe as in claim 13 , comprising about 125 to 250 apertures per square inch of fabric.

15. An apertured dusting wipe as in claim 1 , wherein said apertured dusting wipe is a single layer, staple fiber substrate.

16. An apertured dusting wipe as in claim 13 , wherein said apertured dusting wipe is a single layer, staple fiber substrate.

17. An apertured dusting wipe as in claim 1 , wherein the nonwoven fabric comprises viscose rayon staple fibers, and the latex binder is topically applied to at least one surface of the nonwoven fabric in a total add-on amount, on a solids basis, ranging from about 3 to about 15 g/m 2 .

18. An apertured dusting wipe as in claim 1 , wherein said apertured dusting wipe has a pick-up % of from 9% to 25%.
