Abstract

A method of cleaning residue from a surface includes providing a disposable cellulosic wiper including a percentage by weight of pulp-derived papermaking fibers, and a percentage by weight of fibrillated regenerated independent cellulosic microfibers having a characteristic Canadian Standard Freeness (CSF) value of less than 175 ml and having a weight average diameter of less than 2 microns. The microfibers are further characterized in that 40% by weight thereof is finer than 14 mesh. The wiper is applied with a predetermined amount of pressure to a residue-bearing surface and the surface is wiped with the applied wiper, while applying the predetermined amount of pressure, to remove residue from the surface, such that the surface has less than 1 g/m 2 of residue after being wiped under the predetermined amount of pressure.

First claim

We claim:

1. A method of cleaning residue from a surface, the method comprising:
(A) providing a disposable cellulosic wiper comprising (a) a percentage by weight of pulp-derived papermaking fibers, and (b) from about 10% to about 75% by weight of fibrillated regenerated independent cellulosic microfibers having a characteristic Canadian Standard Freeness (CSF) value of less than 175 ml and having a weight average diameter of less than 2 microns, the microfibers being further characterized in that 40% by weight thereof is finer than 14 mesh;
(B) applying the wiper, with a predetermined amount of pressure, to a residue-bearing surface; and
(C) wiping the surface with the applied wiper, while applying the predetermined amount of pressure, to remove residue from the surface, such that the surface has less than 1 g/m 2 of residue after being wiped under the predetermined amount of pressure with the applied wiper.

2. The method of cleaning residue from a surface according to claim 1 , wherein the surface is selected from the group consisting of glass, metal, ceramic, a countertop, an appliance, and a floor.

3. The method of cleaning residue from a surface according to claim 1 , wherein the surface has less than 0.5 g/m 2 of residue after being wiped with the applied wiper.

4. The method of cleaning residue from a surface according to claim 1 , wherein the surface has less than 0.25 g/m 2 of residue after being wiped with the applied wiper.

5. The method of cleaning residue from a surface according to claim 1 , wherein the surface has less than 0.1 g/m 2 of residue after being wiped with the applied wiper.

6. The method of cleaning residue from a surface according to claim 1 , wherein the surface has less than 0.01 g/m 2 of residue after being wiped with the applied wiper.

7. The method of cleaning residue from a surface according to claim 1 , wherein the percentage by weight of the pulp-derived papermaking fibers is 25% or more.

8. The method of cleaning residue from a surface according to claim 1 , wherein the wiper has more than 25% by weight of the fibrillated regenerated independent cellulosic microfibers.

9. The method of cleaning residue from a surface according to claim 1 , wherein the wiper has more than 30% by weight of the fibrillated regenerated independent cellulosic microfibers.

10. The method of cleaning residue from a surface according to claim 1 , wherein the wiper has more than 35% by weight of the fibrillated regenerated independent cellulosic microfibers.

11. The method of cleaning residue from a surface according to claim 1 , wherein at least 50% by weight of the fibrillated regenerated independent cellulosic microfibers is finer than 14 mesh, has a weight average diameter of less than 2 microns, and a weight average length of less than 500 microns.

12. The method of cleaning residue from a surface according to claim 1 , wherein at least 60% by weight of the fibrillated regenerated independent cellulosic microfibers is finer than 14 mesh.

13. The method of cleaning residue from a surface according to claim 1 , wherein at least 70% by weight of the fibrillated regenerated independent cellulosic microfibers is finer than 14 mesh.

14. The method of cleaning residue from a surface according to claim 1 , wherein at least 80% by weight of the fibrillated regenerated independent cellulosic microfibers is finer than 14 mesh.

15. The method of cleaning residue from a surface according to claim 1 , wherein the fibrillated regenerated independent cellulosic microfibers have a number average diameter of less than about 2 microns.

16. The method of cleaning residue from a surface according to claim 1 , wherein the fibrillated regenerated independent cellulosic microfibers have a number average diameter of from about 0.1 to about 2 microns.

17. The method of cleaning residue from a surface according to claim 1 , wherein the fibrillated regenerated independent cellulosic microfibers have a fiber count greater than 50 million fibers/gram.

18. The method of cleaning residue from a surface according to claim 1 , wherein the fibrillated regenerated independent cellulosic microfibers have a weight average diameter of less than 2 microns, a weight average length of less than 500 microns, and a fiber count of greater than 400 million fibers/gram.

19. The method of cleaning residue from a surface according to claim 1 , wherein the fibrillated regenerated independent cellulosic microfibers have a weight average diameter of less than 1 micron, a weight average length of less than 400 microns, and a fiber count of greater than 2 billion fibers/gram.

20. The method of cleaning residue from a surface according to claim 1 , wherein the fibrillated regenerated independent cellulosic microfibers have a weight average diameter of less than 0.5 microns, a weight average length of less than 300 microns, and a fiber count of greater than 10 billion fibers/gram.

21. The method of cleaning residue from a surface according to claim 1 , wherein the fibrillated regenerated independent cellulosic microfibers have a weight average diameter of less than 0.25 microns, a weight average length of less than 200 microns, and a fiber count of greater than 50 billion fibers/gram.

22. The method of cleaning residue from a surface according to claim 1 , wherein the fibrillated regenerated independent cellulosic microfibers have a fiber count greater than 200 billion fibers/gram.

23. The method of cleaning residue from a surface according to claim 1 , wherein the fibrillated regenerated independent cellulosic microfibers have a coarseness value of less than about 0.5 mg/100 m.

24. The method of cleaning residue from a surface according to claim 1 , wherein the fibrillated regenerated independent cellulosic microfibers have a coarseness value of from about 0.001 mg/100 m to about 0.2 mg/100 m.
