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&#x2033; and a Burst Index greater than about 12.0.

Soft high basis weight tissue

Low slough, high basis weight tissue webs and products are provided. The tissue webs generally have basis weights greater than about 16 grams per square meter (gsm), while maintaining less than about 4 mg of slough. All while yielding tissue products that are both thick and soft.

High basis weight tissue with low slough

In general, the present disclosure is directed to creped tissue webs, and products produced therefrom. The creped webs and products are strong, soft, and have fine crepe structure, such as less than about 12, measured as % COV at a STFI wavelength of 16 to 32 mm, using the test method set forth herein. Fine crepe structure is achieved even at basis weights in excess of 16 gsm per ply.

High basis weight creped tissue

It has now been discovered that the ratio of the wet tensile strength to the dry tensile strength of a tissue web, and more particularly a creped tissue web, can meet or exceed satisfactory levels without the excess use of a wet strength resin. For example, by treating the tissue making furnish with less than about 3 kilograms of wet strength resin per ton of furnish, forming the tissue web, and then creping the tissue web with a creping composition comprising a non-fibrous olefin polymer and a dispersing agent, a tissue web having a CD Wet/Dry ratio greater than about 0.30 may be produced. This discovery provides the flexibility to produce a tissue product with increased wet strength while reducing the add-on of wet strength agent.

Durable creped tissue

The present disclosure relates generally to a tissue product having a creping composition disposed onto at least one surface thereof to increase the softness of the article, while retaining or improving manufacturing efficiency. The tissue products also have a sizing agent that increases the Wet Out time, without negatively impacting softness or machine runability. Preferably the creping composition comprises a cationic component and a film forming component, both of which are preferably water soluble. The cationic component carries a cationic charge that is capable of forming ionic bonds with the negatively charged fibers of the tissue web, thus providing a retention mechanism by which the creping composition is retained on the sheet. The overall retention of the creping composition on the sheet reduces the concentration of the composition in the machine process water, improving machine operability and runability.

Soft creped tissue having slow wet out time

The present disclosure relates generally to a tissue product having a creping composition disposed onto at least one surface thereof to increase the softness of the article, while retaining or improving manufacturing efficiency. Preferably the creping composition comprises a first component that is cationic and a second component that is capable of forming a film. Preferably both the first and second components are water soluble. The first component carries a cationic charge that is capable of forming ionic bonds with the negatively charged fibers of the tissue web, thus providing a retention mechanism by which the creping composition is retained. The overall retention of the creping composition reduces the concentration of the composition in the machine process water, improving machine operability and runability.

Soft creped tissue

The disclosure provides a tissue product comprising at least one multi-layered tissue web that includes a first fibrous layer and a second fibrous layer. The first fibrous layer comprises wood fibers and the second fibrous layer comprises cotton fibers. Cotton fibers are present within the second fibrous layer in an amount from about 1 to about 25 percent by weight of the layer, in some embodiments from about 5 to about 20 percent by weight of the layer, and in some embodiments, from about 10 to about 15 percent by weight of the layer. The selective incorporation of cotton fibers in the tissue web results in a web having improved handfeel without negatively effecting strength and durability.
