Supercritical carbon dioxide cheese dyeing kettle and waterless supercritical carbon dioxide cheese dyeing method
ActiveCN102787459ATextile treatment containersSolvent treatment with solvent recoveryEngineeringDrill
The invention relates to a supercritical carbon dioxide cheese dyeing kettle and a waterless supercritical carbon dioxide cheese dyeing method. In the dyeing kettle, when carbon dioxide fluid enters a distribution tray from an inlet, blades start rotating clockwise under the effect of pressure; inserted drill rods are driven to rotate by a rotation part; and the rotating speed of the inserted drill rods is increased along with the increase of pressure in a cylinder body. When a cheese is dyed, the cheese on the inserted drill rods is dyed at a speed of 0.2-0.5 r / s. When the rotating cheese is dyed, the cheese is subjected to the pressure of the fluid flowing out from a central shaft; the rotation and bicirculation of the cheese dyeing are realized; the uniform dyeing effect of the dyed cheese can be improved; and the migration ability and the diffusibility can be improved.
