摘要：
Neutral sizing mechanism of dispersed anionic rosin size (DRS) was studied. It was shown that the retention of DRS and aluminum increases with the increase of the charge of DRS, PAC or PACP, but gradually decreases with the increase of pH value. Also, calcium carbonate additive was detrimental to the retention, while amphoteric starch additive is beneficial. Accordingly, the sizing effects of these three sizing systems of DRS/PACPc, DRS/PACPa and DPS/PAC are also different and the sequence of sizing effect from good to bad is: DRS/PACPc> DRS/PACPa> DRS/PAC, as predicated by the different retention of DRS and aluminum.
