Abstract: Disclosed are multi-ply tissue products comprising a non-crosslinked binder that are durable and dispersible. The products generally have a Slosh time less than 2 minutes, such as less than about 60 seconds, such as less than about 45 seconds. Surprisingly, the foregoing Slosh times are achieved despite the tissue products having relatively high cross-machine direction (CD) wet tensile strength, such as greater than about 100 g/3". Typically, increasing wet tensile strength, particularly wet CD tensile strength, negatively effects dispersability and increases Slosh time. Despite this trend, the present invention surprisingly provides a tissue product having a relatively high degree of wet strength and good dispersability.

Abstract: Disclosed are non-treated, creped tissue webs, and tissue products produced therefrom, having low stiffness and surface lint. The inventive products may be produced by a print creping process adapted to dispose a non-crosslinked latex polymer on at least one of the outer surfaces of the tissue product. The non-crosslinked latex polymer creping composition does not negatively affect stiffness such that the products generally have a Stiffness Index less than about 5.0, such as from about 2.5 to about 5.0.

Abstract: Disclosed are multi-ply tissue products comprising a non-crosslinked binder that are durable, smooth and with low levels of Slough. In certain instances the creped tissue product have a geometric mean tensile (GMT) from about 700 to about 1,500 g/3", a basis weight from about 45 to about 60 gsm and a Slough less than about 2.00 mg, more preferably less than about 1.50 mg, such as from about 0.10 to about 2.00, such as from about 0.25 to about 1.50 mg. The inventive tissue products also have good durability, such as a Durability Index from about 10.0 to about 20.0, smooth surfaces, such as a TS750 value from about 15.0 to 40.0 and low stiffness, such as a Stiffness Index less than about 10.0.
