  • Patent number: 8834678
    Abstract: 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.

  • Patent number: 8652610
    Abstract: Fibrous products are disclosed containing an additive composition. The additive composition, for instance, comprises a water-soluble film forming component, a first water-soluble modifier component and a hydrophobic polymer component. In some aspects, the additive composition further comprises an additional water-soluble modifier component. The additive composition may be incorporated into the fibrous web by being combined with the fibers that are used to form the web. Alternatively, the additive composition may be topically applied to the web after the web has been formed. In one aspect, the additive composition may be applied to the web as a creping adhesive during a creping operation. The additive composition may improve the perceived softness of the web without substantially affecting the absorbency of the web in an adverse manner.

  • Patent number: 8257551
    Abstract: A soft, layered, single-ply wet-pressed tissue can be made with improved softness by providing one or both outer layers of the tissue with polysiloxane-treated pulp fibers. A particularly suitable wet-pressing process includes pressing a wet tissue web between a felt and a transfer belt to dewater the web, followed by transfer of the dewatered web to a texturizing fabric where the wet web is provided with a three-dimensional texture. Thereafter the texturized web is transferred to a Yankee dryer, dried and creped. The combination of the polysiloxane fibers and the texturizing step provides a particularly effective combination of surface feel, low stiffness and high bulk (caliper).

  • Patent number: 8133353
    Abstract: A creped paper product is provided according to the invention. The creped paper product comprises a result of creping a web of fibers comprising synthetic fibers to provide a creped paper product having a stretch of at least 3% in the machine direction according to TAPPI test T494. The web of fibers can include about 0.5 wt. % to 100 wt. % synthetic fibers based on the total weight of the fibers. In addition, the web of fibers can contain about 0.5 wt. % to about 10 wt. % of synthetic fibers and about 90 wt. % to about 99.5 wt. % of cellulosic fibers. When the web of fiber includes a mixture of synthetic fibers and cellulosic fibers, the creped paper product can be provided having a tear strength in the machine direction according to TAPPI test T494 at least 10% greater than an otherwise identical creped paper product that does not contain synthetic fibers.
