The static stress analysis of supercritical dyeing equipment
Dyeing synthetic fibers with supercritical carbon dioxide has achieved excellent fruit on laboratory scale. Self-developed supercritical C02 fluid dyeing equipment with computer control system was introduced in this paper. In order to confirm the equipment operational safety, the finite element analysis software ANSYS is adopted to analyze static stress of major parts. As a key component of the supercritical dyeing equipment, the coloring matter kettle related tightly with the dyeing process. In our research, the model of the coloring matter kettle was established, and the analysis result of the coloring matter kettle was obtained. These models not only realize the simulation of dyeing process, but also provide the methods for improving the efficiency of dyeing equipment and offer related parameters.
