Mobile dyeing cup for supercritical fluid dyeing and finishing

The invention discloses a mobile dyeing cup for supercritical fluid waterless dyeing and finishing. The dyeing cup achieves separate or simultaneous filling of the medium into multiple dyeing units, and simultaneous heating of the dyeing units for proofing processing. A medium outlet is provided at the lowest position of the bottom of the cup, and the inner surface of the dyeing cup is coated with polytetrafluoroethylene, to effectively reduce residual dye chemicals in the cup and improve the cleaning efficiency. The perforated baffle at the bottom of the cup effectively prevents a textile product from blocking the medium outlet during medium filling and outputting, so that the processing medium and residual dye chemicals can be smoothly discharged. Accordingly, defects of an existing fixed proofing device such as low utilization efficiency, complex cleaning and incapability of meeting the proofing requirements of commercial production are overcome.

Multi-pipe quantitative medium filling system of supercritical fluid dyeing machine

The invention relates to a multi-pipe quantitative medium filling system of a supercritical fluid waterless dyeing machine. The system comprises a supercritical fluid medium reservoir, a stop valve, and a medium filter sequentially connected by a high-pressure main pipe, and at least two filling branches independent of each other and connected to the medium filter. Each filling branch includes a booster pump, a supercritical fluid high-pressure mass flowmeter, a ball valve, and a dyeing unit sequentially connected along a medium forward direction by a high-pressure branch pipe. By using a mass-measurement filling system having multiple branches independent of each other, the invention can effectively realize simultaneous and accurate quantitative medium filling for separate dyeing units and differentiated filling for dyeing units with different medium masses, thus overcoming disadvantages such as unreliability, inaccuracy and low use efficiency of a conventional method, and also making a dyeing operation simple and scientifically feasible.

CONVEYOR-DRIVEN HORIZONTAL FABRIC DYEING MACHINE
20190032260 · 2019-01-31 ·

A conveyor-driven horizontal fabric dyeing machine includes a machine body that is set horizontal and has a bottom to which a liquid storage tank is mounted at a predetermined location and is lower, in position, than the bottom of the machine body. The liquid storage tank has a volumetric capacity that is large enough to accommodate all or most of the amount of dye liquid falling down and returning from a rear end of a dyeing tube so as to greatly reduce the amount of the dye liquid used. Further, alternatively or additionally, a heat exchanger or a filter may be separately mounted in the liquid storage tank or both the heat exchanger and the filter are mounted in the liquid storage tank to carry out temperature raising/lowering and filtration of the dye liquid. As such, the structure of the dyeing machine is simplified.
