The new soybean dregs were used as materials in the study. Four factors affecting the content of natural cellulose was tested with right angle experiment. These factors are caustic strength, temperature, time and the amount of used enzymes. The research established the optimum conditions for extracting soybean dregs. Soybean dregs natural cellulose was made through caustic treatment, hydrolyzation, drying and superpulverization. The production percentage was 85%. The content of cellulose is 80% in the product.
