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 regenerated independent cellulosic microfibers having a number average diameter of less than about 2 microns and a characteristic Canadian Standard Freeness (CSF) value of less than 175 ml. The microfibers are selected and present in amounts such that the wiper exhibits a Relative Bendtsen Smoothness at 1 kg of pressure of at least 1.5 as compared with a like wiper prepared without microfibers. The wiper is applied, with a predetermined amount of pressure, to a residue-bearing surface. 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.

Claims (21)

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 number average diameter of less than about 2 microns and a characteristic Canadian Standard Freeness (CSF) value of less than 175 ml, the microfibers being selected and present in amounts such that the wiper exhibits a Relative Bendtsen Smoothness at 1 kg of pressure of at least 1.5 as compared with a like wiper prepared without microfibers;

(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 includes 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 includes 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 includes 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 the wiper exhibits a Relative Bendtsen Smoothness at lkg of pressure of at least 2 as compared with a like wiper prepared without microfibers.

12. The method of cleaning residue from a surface according to claim 1 , wherein the wiper exhibits a Relative Bendtsen Smoothness at lkg of pressure of at least 2.5 as compared with a like wiper prepared without microfibers.

13. The method of cleaning residue from a surface according to claim 1 , wherein the wiper exhibits a Relative Bendtsen Smoothness at 1 kg of pressure of at least 3 as compared with a like wiper prepared without microfibers.

14. The method of cleaning residue from a surface according to claim 1 , wherein the wiper exhibits a Relative Bendtsen Smoothness at 1 kg of pressure of from about 1.5 to about 6 as compared with a like wiper prepared without microfibers.

15. The method of cleaning residue from a surface according to claim 1 , wherein the wiper has a wiper surface that exhibits a Bendtsen Roughness at 1 kg of pressure of less than 400 ml/min.

16. The method of cleaning residue from a surface according to claim 1 , wherein the wiper has a wiper surface that exhibits a Bendtsen Roughness at 1 kg of pressure of less than 350 ml/min.

17. The method of cleaning residue from a surface according to claim 1 , wherein the wiper has a wiper surface that exhibits a Bendtsen Roughness at 1 kg of pressure of less than 300 ml/min.

18. The method of cleaning residue from a surface according to claim 1 , wherein the wiper has a wiper surface that exhibits a Bendtsen Roughness at 1 kg of pressure of from about 150 ml/min to about 500 ml/min.
