HIGH SOFTNESS, HIGH DURABILITY BATH TISSUE INCORPORATING HIGH LIGNIN EUCALYPTUS FIBER

摘要

A cellulosic tissue includes cellulosic fibers that include at least one of (a) chemically pulped fibers and (b) mechanically pulped fibers. The cellulosic fibers include (i) a percentage by weight of eucalyptus fibers, and (ii) a percentage by weight of regenerated cellulosic microfibers. The cellulosic tissue further includes virgin chemically pulped fibers, with a percentage by weight of recycle fibers. The eucalyptus fibers have been prepared from eucalyptus chips by alkaline peroxide mechanical pulping, exhibiting an ISO brightness of at least 0.82×(% VCP)+0.795×(% RF)^0.98+0.84×(% APMP), in which % VCP is the percentage of virgin chemical pulp in the tissue, % RF, the percentage of recycle fiber, and % alkaline peroxide mechanical pulping (APMP), the percentage of APMP eucalyptus.
