Abstract
It was difficult to separate macro stickies efficiently from recycled pulp for linerboard which consists mainly of old corrugated container and measure them accurately by image analysis method, because the pulp contains much flakes, shives and nonsticky foreign substances besides them.
We improved the image analysis method of measuring macro stickies content, ISO 15360-2, to apply it to the pulp. By the improved method, macro stikies content in the pulp in treatment process was measured and the effect of removal and dispersion of macro stickies with equipments for screening and dispersing was estimated
