HIGH SOFTNESS, HIGH DURABILITY BATH TISSUE WITH TEMPORARY WET STRENGTH

摘要

A multi-ply bath tissue having no more than three plies and no fewer than two plies. The multi-ply tissue has a basis weight of from about 32.6 to about 57.0 g/m2 and includes from about 3% to about 50% cellulosic microfiber, from about 50% to about 97% wood pulp fibers, has a geometric mean (GM) dry tensile of from about 1.37 to 6.33 N/m per g/m2 of basis weight, a cross-machine direction (CD) dry tensile of between about 2.37 to about 4.74 N/m per g/m2 of basis weight, and sufficient temporary wet strength resin to provide an initial Finch Cup CD wet tensile of from about 0.20 to about 1.58 N/m per g/m2 of basis weight. The initial Finch Cup CD wet tensile decays to less than 65% of the initial value in less than fifteen minutes after immersion in water. The product has a caliper of at least 0.078 mm per 8 sheets per g/m2 of basis weight.
