Abstract:
1. A shear-calendering process comprising the steps of: providing a first tissue web, said tissue web comprising pulp fibers; conveying the first tissue web through a gap formed between an outer surface of a rotating roll and an opposing moving surface such that the tissue web contacts the outer surface of the rotating roll and the opposing moving surface, wherein the outer surface of the roll and the opposing surface are moving at different speeds within the gap, the gap calendering the first tissue web while simultaneously subjecting the web to shearing forces sufficient to increase the fuzz-on-edge properties of one side of the web; and combining the first tissue web with a second tissue web to form a multi-ply tissue product, the one side of the first tissue web with increased fuzz-on-edge properties forming an exterior side of the tissue product, wherein the exterior side has a fuzz-on-edge of greater than about 2.0 mm/mm.
