Abstract
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.
