ABSTRACT:
A method for making a collagen strengthened cellulosic sheet by providing a cellulosic pulp slurry; adding solubilized collagen to the pulp slurry, and mixing for a time effective for interaction of the cellulosic pulp slurry and solubilized collagen; forming the interacted cellulosic pulp slurry and solubilized collagen into a sheet; and drying the sheet; also, a method for using solubilized collagen for strengthening paper by mixing the solubilized collagen with a cellulosic pulp slurry; and making a cellulosic pulp product from the mixture and drying.
