From an environmental protection point of view, a necessity of paper recycling has to be highly encouraged by paper industry. Recycling rate of used paper has been increasing, and fibre quality has become worse. For a reason of operation cost reduction, consumption of fresh water has also been restricted. Under such highly closed wet-end condition, various wet-end additives or internal wet-end agents cannot show desirable performance.<BR>We have already introduced a new PAM based type agent, POLYTENTION ( “PT” ) , in recent report. “PT” shows high coagulation force and it can make fibre one-pass retention higher even under severe condition. “PT” also gives favorable paper strength to dried sheet, as compared to the sheet using only retention aids.<BR> “PT” reduces total wet-end additives, and it is expected controlling the paper making conditions.<BR>This report explains floc formation and sheet formation with “PT” and introduces the effect of “PT” under various paper making conditions.
