Advantages of overflow dyeing machine and pressure control
Nov 01, 2018

The overflow dyeing machine will be equipped with a runner during the production process, which will drive the cloth to rotate to a certain extent. The dyeing process of the cloth is mainly in the dyeing of the lower dyeing tank, and the cloth is controlled by controlling the running speed of the cloth. The time of infiltration in the dyeing cylinder also controls the effect of dyeing.

Advantages of overflow dyeing machine

The overflow dyeing opportunity is reasonable to arrange the nozzle, the guide tube and the storage tank, so that the fabric is in a relaxed and unfolded state in different bathing conditions, and the leveling is achieved.

Flow and pressure control of overflow dyeing machine

The flow and pressure during the production process are two important parameters of the overflow dyeing machine, which are determined by the main circulation pump. The flow rate is necessary to ensure that the dye is dyed and exchanged with the fabric, and must be large enough that the variation should be as small as possible during a particular dyeing process. It is completely controlled by the main pump. Pressure for the overflow jet dyeing machine refers to the pressure generated by the nozzle. For the cheese dyeing machine, it refers to the pressure difference between the inside and the outside of the cheese, but the total pressure is still provided by the main pump head.


Overflow dyeing machine can play a very important role in the dyeing process. The different fabrics and processes have different flow rates and pressures (jetting force or pressure difference). For example, in the case of a high-strand fabric with a large surface and a fast dyeing process, the flow rate is required to be large; for a light-weight fabric and a delicate fabric, the spray force is required to be small; and for a fabric having a larger weight, it is required to have sufficient The flow rate also has a strong jet force. Therefore, flow and pressure should vary depending on the fabric and process.
