Abstract

In this research, the effect of adding precipitated Calcium carbonate filler combined with nanocellulose as reinforcement was examined to compensate the strengths loss of papers made of bagasse pulp. About 2% of nanocellulose based on oven dry weight of fibers was suspended in water at 0. 1% consistency and was homogenized by ultrasonic, then was added to the pulp having 15% PCC filler. This mixture was compared with the same sample without adding nanocellulose and without any additives. Cationic polyacrylamide retention agent was added to the pulp suspension at the constant dosage of 0. 14% based on oven dry weight fibers. Statistical analysis of results revealed that the drainage time increased by adding of PCC and nanocellulose system to the bagasse pulp suspension. Addition of nanocellulose has increased filler particle retention due to the formation of adhesive flocs. Prepared SEM images from paper samples confirmed that filler particles flocculation, larger filler retention and their better distribution in paper network. Moreover, in papers filled with PCC and nanocellulose at roughly similar opacity and brightness, loss of strength characteristics due to addion of filler has been compensated. Although relatively higher drainage time of this pulp suspension is substantial limitation, but pretreatment of filler with nanocellulose prior to its addition to the pulp can be further investigated as a promising alternative.
