    Efficiency of four-point bobbin dyeing machine
    Mar 03, 2020

    The first is the metering and feeding system. In the process of dyeing the fabric, it is necessary to pay attention to the time and speed of feeding, because this will have a great impact on the quality of the entire dyeing. We can combine different dyes with the same The color contrast between the dyes promotes better dyeing of the dyed fabric;

    The second is the reversing device and control. It is mainly based on the relevant requirements of the dyeing process. The dyeing liquid can be mechanically circulated, and the direction of the circulation can be changed and controlled by using different square rotations. , The corresponding resistance will also become much larger;

    Once again, the overflow type salt adding device can effectively improve the efficiency of dyeing. After adding an appropriate amount of salt, controlling the concentration of salt can improve the efficiency of dyeing. Remember, the color requirements of different dyeing, The amount of salt to be added will also vary;

    The last is the control of temperature rise and ratio. Everyone should know that during the entire dyeing process, the entire dyeing rate and fixation rate are mainly determined by the rate of temperature rise. If the effective temperature rise is proportional If controlled, the dyeing will be more uniform.
