Application in paper pulp as dry strengthening agent of homemade water in water cationic polyacrylamide (CPAM) emulsion was studied. Good collaborative effect was achieved when Homemade CPAM was used in bleached wheat straw pulp with strengthening agent E and with cationic additives L as paper pulp strengthening agent. It was also showed that distinct strengthening effect was obtained when homemade CPAM emulsion was applied in mixture of wood pulp which was needle bleached kraft pulp (NBKP) and straw pulp, breaking length and tearing index of hand sheet made of mix pulp was respectively increased by 22.2% and17.0% when the dosage of CPAM was 0.8% of dry fiber. Through analysis of handsheet section scanning electron microscopy (SEM) photos, strengthening mechanism of CPAM emulsion to paper pulp was preliminary studied.
