摘要： A multi-ply flushable wipe includes a ply having first and second exterior layers and a middle layer disposed therebetween. Each of the exterior layers includes at least 50% by weight natural fibers. When foam-formed, the middle layer includes at least 25% by weight natural fibers. In embodiments, the middle layer may include at least 75% by weight natural fibers. The middle layer also includes synthetic fibers that have a length within the range of 1 mm and 20 mm. The wipe may have a length weight weighted average fiber length of less than 4 mm and a wet CD strength of greater than 20 N/m. Each ply of the wipe may be formed by wetlaying the first and second exterior layers and a foam formed middle layer to form a web, imprinting the web with a structured fabric, and drying the web. The plies are then attached using a binder.

摘要： The present invention relates to an adhesive comprising of starch and nanocellulose. The adhesive has a nanocellulose concentration of between 0.1 wt % to 12.0 wt % and a starch concentration of between 01 wt % to 12.0 wt % based on the overall weight of the adhesive. The adhesive is produced by combining the nanocellulose and starch at a prescribed ratio and is applied on the surfaces of the paper product to be joined. The present invention also relates to a multi ply pulp product having at least two plies of pulp product joined using an adhesive wherein the adhesive has a nanocellulose concentration of 0.1 wt % to 12.0 wt % and a starch concentration of 0.1 wt % to 12.0 wt % based on the overall weight of the multi ply pulp product.

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.
