  • Patent number: 10233296
    Abstract: A method is presented for forming a collapsed foam film-like structure, the method including positioning a composition applicator adjacent to a hot non-permeable dryer surface, producing a first frothed dispersion or frothed solution from a first dispersion or solution, applying the first frothed dispersion or frothed solution to the dryer surface, allowing the first frothed dispersion or frothed solution to convert to a collapsed foam film-like structure, and scraping the collapsed foam film-like structure from the dryer surface. The method can further include producing a second dispersion or solution, blending the first dispersion or solution and the second dispersion or solution, frothing the blended dispersion or solution, applying the blended frothed dispersion or frothed solution to the dryer surface, and allowing the frothed dispersion or frothed solution to convert to a collapsed foam film-like structure.

  • Publication number: 20130129993
    Abstract: Sheet-like products, such as tissue products made from a low-density web, are disclosed containing an additive composition. The additive composition, for instance, comprises an aqueous dispersion containing an alpha-olefin polymer, and an ethylene-carboxylic acid copolymer. The additive composition may be applied to the surface of the web so that it does not thoroughly or even substantially penetrate the web. For instance, the additive may be applied to one or both surfaces of the web by gravure printing, press coating, spraying or the like. The additive composition may improve the strength of the tissue web and/or improve the perceived softness of the web.

  • Publication number: 20120214373
    Abstract: Substrates such as tissue and nonwovens have an additive composition applied topically thereto. The additive composition, for instance, comprises a frothed aqueous dispersion or solution which is topically applied to the web through a creping process after the web has been formed. The additive composition may be applied in-line to the web as a creping adhesive during a creping operation. In the alternative, the additive composition may be added in an off-line converting process that crepes a dry pre-formed substrate material. The additive composition may improve bulk and softness of the tissue.
