Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A toilet seat has a health monitoring system, including a seat body and two pin joint bases fixed on the rear part of the closestool's upper edge. The seat body has one pin joint axle on both sides of the rear part. Both pin joint axles are connected into the pin joint holes of pin joint bases. The seat body has a weighing Sensor for measuring your weight, an Inductor chip for detecting physical constitution on its upper surface and one displaying and processing device in front. The output signals from the weighing Sensor and the inductor chip are respectively inputted into the displaying and processing device. The gap between the pin joint axle and the pin joint hole is moveable, when weighing, the gap is greater than the distance that the seat body moves downwardly along the measuring sensors.
