Effect of Cellulose Nanocrystal on Coating Properties of Thermal Sublimation Transfer Paper
In this paper,cellulose nanocrystal(CNC)suspension was prepared by acid hydrolysis method and added to SiO2/carboxyl methyl cellulose(CMC)coating to prepare a bio-based coating for thermal sublimation transfer paper.The results showed that CNC had a certain dispersion effect on SiO2/CMC agglomeration.Compared with SiO2/CMC coated thermal sublimation transfer paper,the transverse and longi-tudinal tensile fingers of SiO2/CMC/CNC coated thermal sublimation transfer paper with CNC content of 2.0％increased by 9.2％and 9.3％,the smoothness increased by 31.9％,and the air permeability decreased by 46.0％.The ink absorption value decreased by 3.4％and drying speed increased by 24.3％,the average color density of substrate increased from 1.01 to 1.21,and the ink transfer rate increased from 80.1％to 88.5％.It could be seen that the addition of CNC improved the mechanical and thermal transfer performance of thermal sublimation transfer paper.
