| Abstract:The effects of cellulose nanofibril （CNF） and cationic cellulose nanofibril （C-CNF） on the retention and immobilization of organic pigments were mainly explored in this paper. The results showed that the nanocellulose could form an envelope with organic pigment particles， and the retention and immobilization of pigment were obviously improved. The effect of C-CNF was better with the optimum addition amount of 1.2%， and the pigment retention rate was 46.6%， the rubbing color fastness of paper yarn original paper was 4.2， the tensile index was 31.7 N·m/g. Compared with paper without nanocellulose， the pigment retention rate increased by 33.5%； the rubbing color fastness increased by 2.2 grades and the tensile index increased by 32.1%. |
