Multi-ply tissue products are disclosed. The multi-ply tissue products contain tissue webs that have raised areas and depressed areas. The tissue webs may be constructed so as to be relatively non-compressive and may have a resilient three-dimensional structure. During production, in one embodiment, the tissue webs may be produced without being subjected to any substantial compression, such as a calendering process. Although not necessary in all applications, in one embodiment, the tissue webs may be combined such that the depressed areas contact each other to form the multi-ply product. The tissue webs, for instance, may comprise a through-air dried web in which the raised areas and the depressed areas are molded into the web. Tissue products made according to the present invention have enhanced absorption characteristics. For instance, the tissue products can have an interply absorbency of greater than about 3 g/g after 30 seconds.

Multiple ply tissue products having enhanced interply liquid capacity

Low density, resilient webs are highly calendered to significantly increase density. The resulting tissue has low caliper and stretch but retains good Void Volume and premium-like softness.

Thin, soft bath tissue having a bulky feel

Uncreped throughdried tissue sheets are mechanically treated by calendering and embossing to provide a unique combination of desirable properties to the resulting sheet, which exhibits more surface uniformity, improved softness, high bulk and absorbency.

Embossed uncreped throughdried tissues

The present invention is generally directed to a tissue product with improved flushability. Specifically, the incorporation of both a temporary wet strength agent and an alkaline reagent into the tissue product results in the tissue product having high initial wet tensile strength and a high rate of wet tensile loss. The high rate of wet tensile loss is caused by the high pH of the alkaline reagent that is incorporated during the dry end of a tissue manufacturing process. The temporary wet strength agent is added in the wet end of a tissue manufacturing process. In certain embodiments of the present invention, glyoxylated polyacrylamide may be used as the temporary wet strength agent, while the alkaline reagent may be in dry form or may be encapsulated.

Sanitary tissue products with improved flushability

A soft, flexible yet strong paper product is provided from the unique configuration of particular pulp types, cationic wet strength resins, and anionic processing aids.

High wet and dry strength paper product

The invention relates to tissue products having improved softness properties and methods of making them. Specifically, improved softness is achieved by incorporating one or more softeners/debonders into the fiber furnish at the wet end of the tissue machine prior to formation, followed by a topical treatment with one or more softeners/debonders after the tissue web is dried. The result is a tissue product with added bulk and a smooth surface feel, both properties contributing to improved softness characteristics.

Method for making soft tissue with improved bulk softness and surface

Debonders, particularly including polysiloxanes, are applied to tissue webs by atomizing the debonder and applying the debonder to the tissue with a steam jet as a debonder/steam mixture. The debonder is applied after the creping blade and prior to the reel. Other suitable debonders include quaternary ammonium surfactants.

Method for applying debonding materials to a tissue

Permanent wet strength agents are applied to the surface of the Yankee dryer along with the creping adhesive formulation and thereafter transferred to the tissue web as the tissue web is being adhered to the Yankee. When a sufficient amount of permanent wet strength agent is applied, improved temporary wet strength is attained.

Method of applying permanent wet strength agents to impart temporary wet

Dry strength additives used to enhance the properties of creped tissues are applied to the surface of the Yankee dryer along with the creping adhesive formulation and thereafter transferred to the tissue web as the tissue web is being adhered to the Yankee. When dry strength agents are applied in this manner, less dust and lint are accumulated resulting in improved productivity and product quality.

Method of applying dry strength resins for making soft, strong,

An efficient and effective method for treating tissue making stock to make soft tissues involves adding a softening agent to a first papermaking furnish of short fibers, such as eucalyptus fibers. A second papermaking furnish of long fibers, such as softwood fibers, is blended with the short fiber furnish. Thereafter, wet strength agents and/or dry strength agents are added to the blended furnish. The treated furnish is then fed to a headbox and processed into soft tissue in any suitable manner.

Method of treating a papermaking furnish for making soft tissue

A soft uncreped throughdried tissue product is disclosed having uniformly distributed surface deposits of a chemical composition which imparts a benefit to the user, such as a reduction in skin irritation during use. Particularly suitable compositions are those which have a melting point of from about 30.degree. C. to about 70.degree. C. and which are applied to the outer surfaces of the tissue product in melted form, preferably by rotogravure printing. A suitable composition contains an oil, a wax, and preferably a fatty alcohol.

Soft treated uncreped throughdried tissue

Tissue products having improved bulk and softness are made by adding one or more softeners/debonders and a silicone glycol copolymer of the papermaking fibers at the wet end of the tissue machine, prior to the formation of the tissue web. Suitable softeners/debonders include organoreactive polysiloxanes, quaternary ammonium compounds, quaternized protein compounds, phospholipids, and silicone quaternaries.

Tissue products containing softeners and silicone glycol

The bulk of creped tissue products, such as facial and bath tissue, can be increased by steaming the tissue while stressed in the machine direction of the tissue.
