PULPING PROPERTIES OF RINDS FROM SUNFLOWER SEEDS

In this research, pulping of rinds from sunflower seeds by soda process is studied. Fiber length was 0.89 millimeters and its chemical content, contained 40.5% Cellulose, 30.5% Lignin, 3.33% Ash and 1.93% Extractives. Conditions of Soda process were three different soda consummations of (Chemical ch...
