摘要： The present invention is a method of bonding a fibrous wet laid nonwoven fabric-like product using bacterial cellulose as a binder. The bacterial cellulose most useful for the invention is the type formed in an agitated culture. Microorganisms of the genus Acetobacter which are genetically adapted to be good cellulose producers under agitated conditions are preferred cellulose producers. From 1-30% of the bacterial cellulose may be added to a water slurry of other sheet forming fibers as a binder. Preferably 20% or less bacterial cellulose is used since higher amounts retard drainage rates significantly. Bacterial cellulose conveys many desirable properties such as excellent hydrophilicity with low air porosity and high tensile index. It may be used in many cases as a total replacement for the latex binders now used for manufacture of nonwoven fabrics. Bacterial cellulose is especially well adapted for the manufacture of pattern bonded sheets.

摘要： A fibrous web product with a surface treatment containing bacterial cellulose and a method of surface treating such fibrous webs. The bacterial cellulose is applied to at least one surface of a fibrous web, to make products such as printing material suitable for magazines or advertisements, by use of conventional paper manufacturing equipment. The bacterial cellulose may be applied singularly or in combination with other materials such as fillers or pigments. Bacterial cellulose applied at relatively low concentrations gives excellent properties of gloss, smoothness, ink receptivity and holdout, and surfaces strength.
