  • Patent number: 7828932
    Abstract: 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.

  • Patent number: 7807022
    Abstract: A method of making soft, strong, high bulk tissue is disclosed. The method includes pre-conditioning a wet web by straining the wet web in the cross-machine direction prior to transferring the wet web to a through drying fabric. The pre-conditioned web provides improved sheet softness and conforms more readily to the surface contour of the through drying fabric, thereby creating greater caliper (bulk) in the resulting dried sheet. The bulk is maintained during a subsequent creping step by maintaining the dried sheet in registration with the through drying fabric when the dried sheet is applied to the surface of the creping cylinder.

  • Patent number: 7524399
    Abstract: 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.

  • Patent number: 7497925
    Abstract: Spirally wound paper products are disclosed having desirable roll firmness characteristics and softness properties. The rolled products can be made from a single ply tissue web formed according to various processes. Once formed, the tissue web is subjected to a shear-calendering device that increases the fuzz-on-edge properties of the web and preserves the bulk of the web when wound.

    Abstract: Spirally wound single-ply web products having a chemical additive applied to at least one surface exhibit desirable roll bulk characteristics and softness properties. The rolled products can be made from a single-ply tissue web formed according to various processes. Once formed, the web is subjected to a shear-calendering device that increases the Fuzz-On-Edge properties of the web and preserves the bulk of the web when wound. The shear-calendered web then has a chemical additive applied to at least one surface by a non-compressive application method helping to maintain the Fuzz-On-Edge properties of the web.
