Abstract:
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 mil. The microfibers are selected and present in amounts such that the wiper exhibits a capillary pressure at 10% saturation by extrusion porosimetry of at least twice that of a like sheet prepared without regenerated independent cellulose microfibers.
