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.

Abstract: Pulp fibers can be treated with water insoluble chemical additives resulting in a minimal amount of unretained water insoluble chemical additives present after exposing the treated pulp fibers to process water, liquids, or solutions used in products. One embodiment of the present invention is a method for preparing chemically treated pulp fiber. A fiber slurry is created comprising process water and pulp fibers. The fiber slurry is transported to a web-forming apparatus of a pulp sheet machine thereby forming a wet fibrous web. The wet fibrous web is dried to a predetermined consistency thereby forming a dried fibrous web. The dried fibrous web is treated with a water insoluble chemical additive thereby forming a chemically treated dried fibrous web containing chemically treated pulp fibers.

Abstract: 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.
