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.

A paper product containing hardwood fibers that are treated with certain hydrolytic enzymes, such as endo-glucanases, is provided. Moreover, the paper product includes other types of fibers, such as softwood fibers, that may also be treated with certain hydrolytic enzymes. In addition, other ingredients, such as cross-linking agents, debonders, strength agents, etc., can be applied to further enhance the properties of the paper product. In particular, paper products formed according to the present invention can be strong, soft, and have low lint and slough production.

Papermaking fibers are treated with certain hydrolytic enzymes, specifically including cellulases, such as truncated endo-glucanases, which have been freed of their cellulose binding domain, to generate aldehyde groups at or near the surface of the fibers. Paper sheets made from the resulting fibers exhibit improved strength characteristics relative to paper sheets made from untreated fibers.
