Abstract
This study was carried out to evaluate the effect of PCC loading at thick stock on the physical properties of paper. The effect of starch addition(2, 4 and 6%) and mixing time(5, 10 and 20 min.) on the filler retention and paper properties were investigated. Optimum dosage of cationic starch as a fixing agent was 4%, and mixing time did not showed any significant effect on the filler retention. PCC loading at thick stock was more effective to improve bulk and opacity than PCC loading at thin stock, although their improvement was not so significant. It was also found that the strength properties could be improved by the loading at thick stock. PCC loading method at thick stock could be considered as one of potential approaches for further improving of paper properties, although further research works are required in order to apply the PCC loading at thick stock in the paper mill.
