Articles containing cellulose materials and treated with a chemical additive are disclosed. In accordance with the present invention, at least a portion of the cellulose containing the article is modified to include a first moiety. A chemical additive, such as softener or a humectant, is then chosen that includes a second moiety. When the chemical additive is applied to the article, the second moiety on the chemical additive forms a chemical linkage with the first moiety on the cellulose material. In this manner, the chemical additive becomes bonded to the cellulose material alleviating problems associated with retention. In one embodiment, the present invention is directed to the formation of tissue products, such as facial tissue, bath tissue and paper towels.
L'invention concerne des articles contenant des matériaux de cellulose et traités avec un additif chimique. Selon la présente invention, au moins une partie de la cellulose contenant l'article est modifiée pour inclure une première entité. On choisit alors un additif chimique, tel qu'un ramollissant ou un agent mouillant, qui comprend une seconde entité. Quand l'additif chimique est appliqué à l'article, la seconde entité forme sur l'additif chimique une liaison chimique avec la première entité sur le matériau cellulosique. De cette manière, l'additif chimique devient collé au matériau cellulosique empêchant les problèmes dus à la rétention. Dans un mode de réalisation, la présente invention est dirigée vers la formation de produits de tissu, tels que le tissu facial, le tissu de bain et les serviettes de papier.
