Abstract:
      To address issues including dye loss and contamination during the production process of colored paper, this study proposed to facilitate the fabrication of colored paper using TEMPO-oxidized cellulose nanofibers (TOCNF) due to its high specific surface area and abundant functional groups, which would improve the dye retention rate and reduce the dye content in wastewater. In particular, the dye adsorption performance of TOCNF on reactive red 195 and its influence on dyeing properties and physical properties of colored paper were analyzed. The results showed that TOCNF had a good dye adsorption capacity and the dye adsorption ratio could be up to 30.4%. The dye adsorption performance of TOCNF was enhanced with the increase of temperature, time, dye concentration, TOCNF, NaCl, and Na2CO3 contents. The addition of TOCNF was further proved to significantly improve the coloring (the color difference (∆E) up to 3.81). and strength properties of colored paper.
