The development and application of HTHP gas-liquid dyeing machine not only solves some problems existing in low bath ratio dyeing, but also simplifies the low bath ratio dyeing process, providing a new dyeing method for energy saving and emission reduction. Different from the current airflow atomization dyeing machine, the airflow does not need to carry the atomized dyeing liquid, so energy consumption is not generated, and the power of the fan is greatly reduced.
The airflow of the HTHP gas-liquid dyeing machine also exerts osmotic pressure and latitudinal expansion on the fabric of the adsorbed dye liquor while the fabric is being circulated; the levelness of the fabric in a single cycle is improved, and the occurrence of creases is avoided. The front combined dyeing nozzle of the high temperature and high pressure jet dyeing machine can provide different forms of exchange for the fabric, which improves the degree of leveling of the dyeing and dyeing fabrics in a single cycle and shortens the dyeing time.
When washing, the dyeing nozzle forms a countercurrent exchange with the fabric, which not only improves the cleaning effect, but also has high efficiency and saves water. Compared with the current airflow atomization dyeing machine, it can save more than 50% of electricity, save 20% of water, save steam by 30%, and shorten the process time by one third. While improving the dyeing processability, it also highlights the technical features of energy saving and consumption reduction.
Because the new design principle is adopted, the airflow and the dyeing liquid are separately controlled, so the airflow in the high-temperature and high-pressure jet dyeing machine does not generate energy consumption to the dyeing liquid, and the fan power is greatly reduced. At the same time, it also inherits the characteristics of uniform dyeing of fabrics with good dyeing, and the extrusion of the cloth roll and the penetration of air pressure, thus improving the degree of leveling of the dyed fabric in a single cycle. Uniform dyeing is completed in a short period of time.
