Abstract:
A method of making sanitary paper products from coarse fibers, comprising:pulping coarse fibers in water with agitation to produce a pulp slurry, the pulp from the coarse fibers having an average fines content of greater than about 40%, wherein the pulp comprises cellulosic fibers at least 60% having a Kajaani coarseness greater than 12 milligrams per 100 meters; using an effective amount of pulp washing to remove containments and to reduce the fines content to less than about 35% and increase the Canadian Standard Freeness by more than about 50, said pulp washing conducted substantially directly after said pulping such that prior to said washing the fibers are refined or defibered substantially only to the extent resulting from said pulping; introducing the washed pulp at a papermaking consistency into the headbox of a papermaking machine; and utilizing the pulp in the papermaking machine to produce sanitary paper products having a superior handfeel when compared to an identical product without undergoing fines removal.
