Improvement of paper properties by impregnation in cellulose derivative solution. 2. Carboxymethyl cellulose solution

Paper sheets prepared from bleached bagasse and paper grade wood pulp were impregnated in a carboxymethyl cellulose solution. After drying the prepared samples were cured at 100°C or 140°C. The measured improvement of the mechanical properties of the treated samples depends on time and concentration of the dipping bath and on the curing conditions.
