Method of cleaning residue from a surface using a high efficiency disposable cellulosic wiper |
| 摘要 |
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 independent regenerated 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 oil residue removal efficiency of at least 150% as compared with a like sheet without independent regenerated cellulosic 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/m2 of residue after being wiped under the predetermined amount of pressure. |

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 oil residue removal efficiency of at least 150% as compared with a like sheet without fibrillated regenerated independent cellulosic 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/m2 of residue after being wiped under the predetermined amount of pressure with the applied wiper. |
