High efficiency disposable cellulosic wiper |
| 摘要 |
A disposable cellulosic wiper includes 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. |

1. 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. |
