In the paper manufacturing, drying process needs much energy. To reduce drying energy, this study applied 3~5% of wood flours as spacers to increase the old corrugated container (OCC) solid contents in wet pressing. The mixed furnish of OCC and wood flour increased bulk, drainage rate and solid contents, while decreasing strength properties such as breaking length, and compressive index. This study tried to keep paper strength while increasing bulk, solid contents, and drainage rate at the same time by applying cationic starch, drainage aid, and rod shape wood flours.
The results of the study were summarized as followed;
1. The solid contents of mixed furnish started to be higher than 100% OCC furnish at about 53% solid contents level. Slid contents is further increased by adding strength agent and drainage agent.
2. Bulk of OCC furnish containing wood flours increased at all conditions.
3. Cationic starch made recovery of strength property loss caused by adding wood flour. Rod type wood flour was found to be more effective than spherical type of wood flour.
