Description
technical field [0001] The invention relates to the technical field of fluid dyeing, in particular to a pressure dyeing fluid dynamics measuring device. Background technique [0002] In the process of textile dyeing, the flow state of the dyeing fluid and the difference in the Reynolds number when the dyeing fluid flows often cause changes in the movement mode and velocity of the dye particles in the dyeing fluid, and also cause differences in the thickness of the boundary layer on the fiber surface. It has a significant impact on the dyeing kinetic parameters such as the diffusion rate and diffusion coefficient when the dye particles are adsorbed on the dyed fiber, thus affecting the dyeing performance of the textile. [0003] In the existing textile dyeing and finishing process, the dyeing machines used include overflow dyeing machines, jet dyeing machines and airflow dyeing machines, etc. These dyeing machines mainly include dyeing tanks, pumps, heat exchangers, filters, ...
