A Survey of Soy Protein as a Novel Dry Strength Agent for Papermaking

Abstract:

In this paper, soy protein papermaking process conditions as dry strength agents were studied. The results show that a part of the three parts of soy protein and a mixed system with a cationic starch alone, or cationic starch, soy protein, as compared to dry strength additives will significantly increase the strength. The optimum conditions were: pulp types E, defatted soy protein, dry vacuum drying method is 105°C, adding ways to add the pulp, the best reaction time was 10min, the optimum dosage of 2%. Soy protein sources are widely readily available, and environmentally friendly and easily biodegradable, paper dry strength agents as a good material.
