摘要
本研究主要探讨了纤维素纳米纤丝(CNF)和阳离子化纤维素纳米纤丝(C-CNF)对有机颜料留着和固定化的影响。结果表明,纳米纤维素可以和有机颜料颗粒形成包络体,显著提高颜料的留着和固定化。其中,C-CNF的作用效果更好,最佳含量为1.2%,颜料留着率为46.6%,纸纱原纸的摩擦色牢度为4.2级、抗张指数为31.7 N·m/g,相比未添加纳米纤维素时,颜料留着率提高了33.5%;纸纱原纸的摩擦色牢度提高了2.2级,抗张指数提高了32.1%。
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 parti‐cles,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 in‐dex was 31.7 N·m/g.Compared with paper without nanocellulose,the pigment retention rate increased by 33.5%;the rubbing color fast‐ness increased by 2.2 grades and the tensile index increased by 32.1%.
