CNF-CMC梯度网络结构固定有机颜料对纸纱原纸着色效果的影响
The effect of CNF-CMC gradient network structure fixed organic pigment on the coloring efficacy of paper yarn base paper
摘要
Abstract
Traditional paper dyes are easy to fade under photothermal conditions,in contrast,waterborne organic pigments have excellent tinctorial strength and high light and weather re-sistance,which can meet the requirements of high-end paper yarn to coloring efficacy and light fastness of the colorants.However,the lack of chemical and hydrogen bonds between organic pigment particles and plant fibers,and the pigments are difficult to fix in the struc-ture of the paper.In this study,cellulose nanofibers(CNF/TOCNF)were used as the prima-ry skeleton network and carboxymethyl cellulose(CMC)macromolecules were used as the second-order reinforcement network,together construct a multi-level gradient network to en-close and fix organic pigment particles.The dispersion and fixation of the pigment particles are realized by double coating.The results show that the coloring efficacy and colorfastness of the paper yarn base paper can be improved significantly by using the gradient network to fix the pigment particles,and has a positive effect on improving the strength and roughness of the paper.This study has an important role in solving the problem of coloring technology in the production of high-end paper yarn.关键词
