The use of starch in the paper industry

The properties of natural starch. modified method and employed effect of three types of modified starches including cationic starch, oxidized starch and phosphate ester starch are described in this paper. Cationic starcl can bring a improvements in strength of paper, retention of fines and draining in wet end. Oxidized starch used in surface sizing can increase the surface strength of paper. Phosphate ester starch which can increase the sizing value is an effective internal rosin sizing aid.
