Patent

CA 2267151

The invention relates to tissue products having improved softness properties and methods of making them. Specifically, improved softness is achieved by incorporating a cationic amidoamine into the fiber furnish at the wet end of the tissue machine prior to formation and/or by topical addition to the tissue web. One or more softeners/debonders can be added to the furnish and/or topically applied to the tissue web after the tissue web is dried. 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 dotés de caractéristiques améliorées de douceur ainsi qu'à des procédés de fabrication de ces produits. On obtient spécifiquement cette douceur accrue en incorporant une amidoamine cationique à la composition de fabrication fibreuse, au niveau de la partie humide de la machine à papier, avant la formation dudit papier et/ou en l'ajoutant de manière topique sur la bande de tissu-papier. On peut également ajouter des agents adoucissants ou des agents susceptibles de casser les liaisons à la composition de fabrication et/ou les appliquer de manière topique à la bande de tissu-papier après séchage de cette dernière. 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.
