Structure and strengths of paper have been studied by analyzing fibers characteristics depending on refining methods. In those studies stock preparation aspect of softwood and hardwood fibers mixing and fibers characteristics was focused for paper quality improvement. In this study drainage of fibers were analyzed to improve the production efficiency and paper product's quality. Fiber properties by one and two-step refining processes were compared. By applying two-step refining processes(2.8 kg_f and 5.6 kg_f of refining load), refining efficiency, drainage, and strengths could be improved at specific extent of refining.
