High efficiency disposable cellulosic wiper
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 ml. The microfibers are selected and present in amounts such that the wiper exhibits a Laplace pore volume fraction at pore sizes less than 15 microns of at least 1.5 times that of a like wiper prepared without regenerated independent cellulosic microfibers.
