Abstract

Flocculation of fibers and its distribution in paper are related to flocculation mechanisms, retention and drainage. Relationship between flocculation mechanisms and physical properties of paper has not been fully studied. In this study, flocculation of fibers was investigated by changing microparticles for flocculation mechanism analysis. When fillers were not added, formation and strength were deteriorated by 100, 300, or 500 ppm of linear PAM (all L-PAM), All L-PAM + 1200 ppm inorganic microparticle (1200-IM), all L-PAM + 120 ppm organic microparticle (120-OM), all L-PAM + 1200 ppm organic microparticle (1200-OM) because of too much flocculation. When 5, 15, $25\%$ (od.w/w) fillers were added, retention and drainage process were not affected by the extent flocculation when 500 ppm L - PAM, 500 ppm L - PAM + 1200- IM, and 500 ppm L - PAM + 120 ppm OM were added.
