Abstract

The impact of chemical treatment variables including treatment time and temperature, chemical charge as well as pulp FREENESS on fiber quality of COLZA stem CHEMI-MECHANICAL PULP was studied using Fiber Quality Analyzer (FQA). Three treatment times (15, 30 and 45 minutes), two treatment temperatures (125 and 145°C), two chemical charges (4% NaOH+8% Na2SO3 and 8% NaOH+12% Na2SO3) as well as pulp refining were evaluated. The results revealed that at higher values of treatment variables, fiber average length was reduced and varied between 0.49 and 0.65 mm. However, the influence of pulp refining on fiber average length was not very pronounced. Pulps contained between 55-63% FINES, which is on the high range and refining increased the fine content by 5%. Fiber COARSENESS varied between 10 and 41 mg/100m which was raised to 14 and 53 mg/100m upon refining. Even though refining did not alter fiber CURL, but fiber KINKs were increased.
