  • 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.

  • Patent number: 7252870
    Abstract: Nonwoven materials having a pattern incorporated into the materials are disclosed. The nonwoven materials may be, for instance, tissue webs, meltspun webs such as meltblown webs or spunbond webs, bonded carded webs, hydroentangled webs, and the like. The pattern may be incorporated into the webs using various techniques. For instance, the pattern may be formed into the web by topically applying a bonding material. In an alternative embodiment, the pattern may be formed according to a thermal bonding process. The pattern contains individual cells that include two spaced apart expanded regions separated by a constricted region. By incorporating the pattern into the web, a material is produced having a relatively low Poisson ratio.
