TeintureIndex. décimale : 667.3 Teinture et impression des tissus Résumé : The compatibility of three disperse dyes, CI Disperse Orange 30, CI Disperse Red 167 and CI Disperse Blue 79, which are commonly used as a trichromatic combination for conventional dyeing, was studied in supercritical carbon dioxide dyeing. Both the dyeing rate and the build-up of the selected dyes were measured. Experimental results showed that they were quite compatible. The dyeings of a binary combination (CI Disperse Orange 30 and CI Disperse Blue 79, mass ratio 1:1) and a ternary combination (CI Disperse Orange 30, CI Disperse Red 167 and CI Disperse Blue 79, mass ratio 1:1:1) at different dye concentrations showed an on-tone uptake and presented the same metric hue angles. This proved that the selected dyes could form a useful trichromatic combination in supercritical carbon dioxide dyeing. Furthermore, the uptake and exhaustion of the single dyes in supercritical carbon dioxide dyeing were similar to those in aqueous dyeing, implying that the dyeing media play only a minor role in the dyeing of polyester fibres with disperse dyes.

Verre -- RevêtementsIndex. décimale : 667.9 Revêtements et enduits Résumé : Films composed of nanoparticles have been commonly used in decorative applications due to their striking colors and useful self-cleaning properties. An efficient option for the structural coloration has been developed through fabrication of the thin films on substrates from SiO2 nanoparticles and PEI. The surface morphology and microstructure of SiO2/polyethyleneimine (PEI) film on glass substrate were analyzed with an SEM, AFM, and thickness analyzer. The homogeneous coatings of limited SiO2 aggregation with air voids were formed on glass substrates. It was strongly suggested that optical properties of the films came from the single-layer thin film interference effect. The structural colors of SiO2/PEI films were captured by digital camera, integrating sphere spectrophotometer and multi-angle spectrophotometer. The results indicated that the films illuminated distinctly as the thickness increased, and presented different lightness values and hues at various viewing angles. Moreover, those films with some surface roughness exhibited high water static contact angle, which endowed the films potential hydrophilicity and self-cleaning property.
