ABSTRACT:
A cellulose dope prepared by subjecting a slurry of cellulose to cavitation either before, during or after treatment with a solvent. The cavitation results in the efficient fibrillization or delamination of the pulp fibers by peeling back the layers of fiber. The cavitation makes the fibers highly accessible to solvents for dissolution. One preferred cellulose solvent is sodium hydroxide at soda cellulose Q condition.
