Abstract

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 charge) 14%, 16% and 18%. Liquor on RINDS ratio, was equal to 6, and period of digestion was 30 minutes. Yield and Kappa number on the best choice of conditions of PULPing (165 degree of centigrade temperature and 16% soda consumption) were measured respectively 55.7% and 74.96.Using PFImill, four kinds of PULPs with four different free nesses were produced from the proper PULP and were changed to hand sheets. Study on mechanical strength of hand sheets showed that beating has no effect on tear strength from 30 to 40 SR and it reduces this strength after more beating. Practically, no effect was observed on burst strength and breaking length during beating from 30SR to 60SR. This lignocellulose, agricultural residue is a cheap by-product in Sunflower-oil producer factories. Some of them is as a food for live-stocks and some is burned as a source of energy. Because of this, using rind from sunflower seeds in PAPER and other cellulosic industries can be useful.
