Abstract

This research with purpose to distinguish properties of Pulping and Paper making from stem of COLZA (Brassica napus) and capability of Semi-chemical Pulping was performed. The exception was Type selection of used tests was Ocapie that was prepared from center of modification of seeds, karaj county and transferred to the Mazandaran Pulp and Paper mill. In Conditions of Cooking process, were two different chemicals consumption (chemical charge) 10% and 20 % on the (basis of dry) COLZA weight and periods of digestion were 30 and 40 minutes and the condition of pulping was 170 degree of centigrade temperature. Using PFImill,four kinds of pulps with four different freeness were made up to 410±25 CSF by PFI mill refiner. Then seven hand sheet 127gr/m² were made measured. For study the resistant properties of hand sheet papers, used the TAPPI standard, study on mechanical strength of handsheets showed that when the yield decreased, the resistance index of paper like that: Tensile Strength, Ring crush Test (RCT), Burst Strength, Burst Strength, Stiffness, Strage, Breaking Length Corrugated Medium Test was increased.
