CA 2267147

The invention relates to tissue products having improved softness properties and methods of making them. Specifically, improved softness is achieved by incorporating a silicone quaternary and, optionally, one or more softeners/debonders into the fiber furnish at the wet end of the tissue machine prior to formation, followed by an optional topical treatment with a silicone quaternary and/or one or more softeners/debonders after the tissue web is formed. The result is a tissue product with added bulk and a smooth surface feel, both properties contributing to improved softness characteristics.

Cette invention se rapporte à des produits en papier présentant des caractéristiques améliorées de douceur ainsi qu'à des procédés de fabrication de tels produits. On améliore spécifiquement la douceur de ces produits en incorporant un composé quaternaire siliconé, et éventuellement, un ou plusieurs agents adoucissants ou agents susceptibles de rompre les liaisons, à une composition de fabrication fibreuse, au niveau de la partie humide de la machine à papier, avant la formation dudit tissu-papier, puis en effectuant facultativement un traitement topique avec un composé quaternaire siliconé et/ou un ou plusieurs agents adoucissants ou agents susceptibles de rompre les liaisons après la formation dudit tissu-papier. On obtient de cette manière un produit en papier présentant un bouffant accru et un toucher superficiel doux, ces deux caractéristiques contribuant à conférer audit tissu-papier ses caractéristiques améliorées de douceur.
