Colorants -- Solubilité
Colorants dispersésCatégorie de colorants très peu solubles dans l'eau, utilisés à l'origine comme colorants pour l'acétate, et qui généralement sont appliqués sous forme de suspensions aqueuses de faible concentration.Les colorants dispersés sont largement utilisés dans la teinture de la plupart des fibres manufacturées, surtout le polyester.

| Résumé : |
This feature article describes a promising technique that can shed new light on the behaviour of one of the most commercially important classes of textile colourant. Disperse dyes are the only industrially significant means of exhaustion dyeing polyester, the highest-volume synthetic textile material. Successful coloration depends upon disperse dye solubility. However, accurate measurement of this parameter at typical operating conditions is not an easy feat. In addition, numerous previous studios examining solubility have net factored in strong influences that will affect real-world disperse dye formulations. These aspects include physical form and the presence of additives. The methodology reported in this Feature article addresses such Shortcomings. It is capable of providing insights into the performance of marketed products under the exact conditions of their application, which has hitherto not been possible. This novel approach allow technologists to compare the impact of subtle differences in variables such as colorant particle size distribution, impurity profile, and dispersant concentration an solubility. In doing so, it could facilitate the design of better-performing and more cost-effective disperse due systems. |
