Beschreibung
Zusammenfassung:	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 20 to about 35 lbs per 3000 sq foot ream 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 17 to 80 g/3 in. per pound of basis weight, a cross-machine direction (CD) dry tensile of between about 30 to about 60 g/3 in. per pound of basis weight, and sufficient temporary wet strength resin to provide an initial Finch Cup CD wet tensile of from about 2.5 to about 20 g/3 in. per pound 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 5 mils per 8 sheets per pound of basis weight.
