摘要： A ply-bonding agent or adhesive composition characterized by a viscosity and a surface tension for the manufacture of paper tissue and paper towel, includes: (a) water; (b) nanofibrillated cellulose; and (c) one or more modifiers effective to modify either or both of (i) the viscosity of the composition or (ii) the surface tension of the composition, wherein the one or more additional modifiers are selected from the group consisting of components (iii), (iv), (v), (vi), (vii) or (viii), wherein: (iii) is PVOH and a viscosity modifier; (iv) is a viscosity modifier; (v) is a viscosity modifier and a surface tension modifier other than PVOH; (vi) is a water-soluble cellulose derivative; (vii) is a water soluble polyol; and (viii) is a surface tension modifier other than PVOH. The compositions are particularly useful for ply-bonding multi-ply absorbent sheet when the plies are treated with debonder.

摘要： A roll of absorbent sheet tail-sealed with an NFC containing aqueous tail-seal adhesive includes an NFC containing aqueous tail-seal adhesive interposed between a tail of the roll of absorbent sheet and an underlying convolution of the roll adhering the tail to the underlying convolution to form the tail-seal. The NFC containing tail-seal adhesive comprises nanofibrillated cellulose and one or more additional components selected from the group consisting of components (i), (ii), (iii), (iv) and (v) wherein (i) is a water-soluble cellulose derivative; (ii) is a water soluble polyol; (iii) is a viscosity modifier other than a water soluble cellulose derivative; (iv) is PVOH; and (v) is PVOH and a viscosity modifier. The NFC containing tail-seal adhesive optionally includes a surface tension modifier other than PVOH.

摘要： A multi-ply absorbent sheet includes a first absorbent ply of cellulosic sheet; a second absorbent ply of cellulosic sheet; and a ply bonding adhesive interposed between the first absorbent ply and the second absorbent ply, the ply-bonding adhesive thereby adhering said absorbent plies together. The ply-bonding adhesive comprises polyvinyl alcohol and nanofibrillated cellulose. In a particularly preferred embodiment the adhesive is applied as a dilute aqueous composition to tissue plies and the nanofibrillated cellulose has a Characteristic Breaking Length of 6.5 km or above.
