Patent

CA 2670281

Sheet-like products, such as tissue products, are disclosed containing an additive composition. The additive composition, for instance, comprises an aqueous dispersion containing an alpha-olefin polymer, an ethylene-carboxylic acid copolymer, or mixtures thereof. The alpha-olefin polymer may comprise an interpolymer of ethylene and octene, while the ethylene-carboxylic acid copolymer may comprise ethylene-acrylic acid copolymer. The additive composition may also contain a dispersing agent, such as a fatty acid. The additive composition may be incorporated into the tissue 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. The additive composition can improve various properties of the sheet-like product. For instance, in one embodiment, the additive composition can reduce lint and increase softness.

Produits de type feuille, tels que des produits en tissu à jeter, contenant une composition d'additif. Ladite composition comprend par exemple une dispersion aqueuse contenant un polymère d'alpha-oléfine et un copolymère d'éthylène-acide carboxylique, seuls ou mélangés entre eux. Le polymère d'alpha-oléfine comprend un interpolymère d'éhylène et d'octène alors que le copolymère d'éthylène-acide carboxylique peut contenir un copolymère d'éthylène-acide acrylique. La composition d'additif peut également renfermer un agent dispersant tel qu'un acide gras. La composition d'additif peut être intégrée dans le voile du tissu par combinaison avec les fibres utilisées pour former le voile. En variante, la composition peut être appliquée topiquement au voile après formation de ce dernier. La composition d'additif permet d'améliorer diverses propriétés du produit en feuilles. Dans un mode de réalisation par exemple, la composition d'additif permet de réduire le peluchage et d'accroître la douceur.
