Evaluasi Perubahan Fiber Morfologi Yang Terjadi Pada Pergantian Grade Product Dalam Produksi Dissolving Pulp

Along with the development of technology, dissolving pulp has various types, such as dissolving pulp with 100% Acacia crassicarpa and 100% Eucalyptus wood composition. Dissolving pulp is a special type of pulp with high alfa cellulose content above 94%. Dissolving pulp with A.crassicarpa composition has different morphology and physical properties from Eucalyptus wood composed. To change dissolving pulp into another products also requires time that needs to be calculated. Each one turn to change the dissolving pulp product is called one campaign (batch). The idea in this Final Project is entitled “Evaluation of Fiber Morphology Changes that Occur at Grade Product Change in Dissolving Pulp Production”, with the objective of evaluating changes in fiber morphology, changes in physical properties and estimating the time required for wood composition. The difference in fiber morfology while changing dissolving pulp products causing significant alteration. Fiber length decreased by an average of 5.35%. The cell wall thickness has increased by an average of 10.98%. Meanwhile fiber population decreased by an average of 9.71%. The time required for product turnover is ± 14 hours (indication based on fiber morfology values compared to calibration values). The difference in physical properties values between the two types of dissolving pulp is different for each campaign. The freeness value of A.crassicarpa increased by 5.42% while Eucalyptus increased by 3.72%. The bulk value of A.crassicarpa increased by 3.52 % and Eucalyptus increased by 1.21 %. The tensile index value of A.crassicarpa decreased by 3.21 % and Eucalyptus decreased by 3.29 %.
Key Word: Dissolving pulp, fiber morphology, physical properties, time estimation
