ABSTRACT:
Single-ply throughdried tissue sheets, particularly suitable as bath tissue, are produced with at least three layers. One or both of the outer layers suitably contain predominantly softwood fibers and a chemical bonding agent. One or more of the inner layers suitably contains a chemical debonder. The resulting tissues have a high level of durability and softness.
