Abstract:
The present invention provides a method and system for measuring disintegration of a fibrous product. The method comprises disintegration of a sample of the fibrous product in an aqueous solution, optionally promoted by mechanical energy, passing the aqueous solution through a screen to obtain a permeate and retained fraction on the screen, and analyzing at least one parameter from the permeate for example by a gravimetric analysis, an optical analysis, an electrochemical analysis, a volumetric analysis, or combination thereof. Advantages include adjustabilxity, speed, and high correlation with actual flushability or repulpability of the fibrous product, and utility in a process for manufacturing a fibrous sheet exhibiting con- trolled disintegration, such as a flushable or repulpable fibrous sheet.
Abstract:
The present application provides chemically treated fibrous structures, tissue products and a method of manufacturing thereof, wherein the fibrous structure comprises a textured background surface, a design element formed by removing a portion of the textured background, the design element lying between the surface and bottom planes of the fibrous structure, and an additive composition selectively disposed on the design element. The method of manufacturing said patterned tissue product comprises the steps of (a) providing a tissue web having a textured top surface lying in a surface plane and a bottom surface lying in a bottom plane wherein there is a z-directional height difference between the surface plane and the bottom plane; (b) conveying the web through a first nip created by a first receiving roll and a pattern roll having a plurality of protuberances forming a design pattern; (c) conforming a portion of the web to the protuberances; and (d) applying a chemical papermaking additive to an applicator rol l; (e) conveying the web through a second nip created by the pattern roll and the applicator roll; (f) transferring the additive from the applicator roll to the conformed portion of the web; and (g) conveying the web into a second nip formed between the pattern roll and a second receiving roll.

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 hydroentangled nonwoven sheet material can be produced by a process which comprises: 0) optionally providing a polymer web on a carrier, a) providing an aqueous suspension containing short fibres and a surfactant; b) depositing the aqueous suspension on the carrier, c) removing aqueous residue of the aqueous suspension deposited in step b) to form a fibrous web, b') depositing aqueous suspension on a surface of the fibrous web formed in step c), c') removing aqueous residue of the aqueous suspension deposited in step b') to form a combined fibrous web, d) hydroentangling the combined fibrous web, and optionally e) drying the hydroentangled web, and/or f) further processing and finalising the dried, hydroentangled web the web to produce the nonwoven end material. The hydroentangled non-woven sheet material obtainable by this process has a low degree of surface irregularity and contains low residues of surfactants.
