Abstract

In this research, effect of freeness on mechanical properties of papers made from COLZA with three different freeness was performed. Type selection of used was prepared from center of modification of seeds, karaj county and transferred to the Mazandaran PULP and Paper mill. Best choice of condition of PULPing was 170 degree of centigrade temperature and 20% chemical consumption and period of digestion was 40 minutes. And than by using PFI mill, three kind of PULPs with three different freeness were produced from the proper PULP and then, 127gr/m2 hand sheet papers produced from different samples of PULPs and their strength properties were measured study of mechanical strength of hand sheets showed that the beating has effect on tear strength and reduces this strength with more beating when the refining increased, the resistance indexes of paper such as ring corrugated medium test (CMT), ring crush test (RCT), stiffness; and other strength was increased the only exception was tear strength that decreased. With regard to reduces of tear strength that no important for linear boeard and increases ring crush test (RCT) and curugated medium test (CMT) and stiffness and other strength resulted PULPs with 300±25 (CSF)is recommended.
