Paper Products Incorporating Surface Enhanced Pulp Fibers and Having Decoupled Wet and Dry Strengths and Methods of Making the Same

A method of making a paper product can comprise making one or more sheets at least by, for each of the sheet(s), forming a web from one or more furnishes that comprise fibers dispersed in water. The fibers of the furnish(es) can comprise a plurality of first fibers that are hardwood fibers and a plurality of second fibers that include softwood fibers and surface enhanced pulp fibers (SEPF), the SEPF having a length weighted average fiber length of at least 0.20 mm. The method can comprise at least partially dewatering the web to form the sheet. The sheet(s) can be laminated and/or embossed such that a total dry tensile strength of the paper product is less than or equal to 90% of the sum of the total dry tensile strength(s) of the sheet(s).

Soft high basis weight tissue

The present invention provides multi-ply creped tissue products, and in particular embodiments creped wet pressed tissue products, having substantially higher per-ply basis weights, such as from about 20 to about 30 gsm, without the negative effects often associated with higher basis weight. As such, the tissue products are generally soft and flexible, having a softness value (measured as TS7) less than about 12.0 and a Stiffness Index less than about 20. While being soft and flexible, the instant tissue products are durable enough to withstand use, such as having a GMT greater than about 600 g/3″ and a Burst Index greater than about 12.0.

Papermaking fabrics having machine and cross-machine direction elements and paper products made therewith

The present invention discloses tissue products, specifically rolled paper towel products, such as one, two or three ply tissue products having a basis weight greater than about 35 gsm and a GMT greater than about 1,500 g/3″. The products have a three-dimensional surface, typically the air contacting surface, comprising substantially continuous machine direction (MD) oriented elements, discrete cross-machine direction (CD) oriented elements and discrete MD oriented valleys having valley sidewalls formed by the MD oriented elements and valley endwalls formed by the CD oriented elements. The discrete valleys generally have a length greater than about 10.0 mm. The CD oriented elements comprise a relatively small percentage of the tissue surface area, such as less than about 15 percent, yet the tissue products display good anti-nesting properties when spirally wound into rolls, such as a Roll Structure greater than about 1.75.

EMBOSSED MULTI-PLY TISSUE PRODUCTS

Disclosed are embossed, multi-ply tissue products having consumer preferred physical properties and an aesthetically pleasing appearance. The products may comprise a first embossed tissue ply and a second embossed tissue ply arranged in facing relation and defining an interior portion there between, the first ply comprising a plurality of first embossments oriented towards the interior portion of the product and the second ply comprising a plurality of second embossments oriented away from the interior portion. The products generally have improved sheet bulk, such as a sheet bulk greater than about 15 cubic centimeters per gram (cc/g), and improved softness, such as an Average TS7 less than about 12.0.

Durable and dispersible creped multi-ply tissue

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.

FOAM-ASSISTED APPLICATION OF UNCOOKED STARCH AND DRY STRENGTH AGENTS TO PAPER PRODUCTS

Multi-ply paper products and methods for manufacturing such products are provided. A method includes producing a foam of water, air, a foaming agent, uncooked starch, and a dry strength agent; applying the foam to a first surface of a base embryonic ply web; providing an applied embryonic ply web having a first surface and contacting the first surface of the base web with the first surface of the applied web at an interface to form a combined ply web; and selectively applying vacuum pressure to a second surface of the base web to retain particles of the uncooked starch on or near the first surface, to draw molecules of the dry strength agent into the base web and/or to the first surface of the applied web to retain particles of the uncooked starch in the interface and to draw molecules of the dry strength agent into the applied web.
