Working Principle of GBM Serial Beam Dyeing Machine

1. Fabric Loading and Dye Circulation Basics
When the fabric is wound on the warp beam and placed inside the dyeing machine, the circulation system of the dyeing machine begins to work. It mainly consists of a circulation pump, pipes, and nozzles. After the circulation pump is started, it will generate power to make the dye flow throughout the system. The dye is extracted from the dye tank at the bottom of the dyeing machine and transported through the pipe.
2. Dye Flow and Fabric Dyeing Process
One-way flow dyeing: The dye flows from the inside of the warp beam to the outside at a certain pressure and flow rate under the action of the circulation pump. In this process, the dye will penetrate the fabric on the warp beam. Since the fabric on the warp beam is tightly arranged in a roll, the dye will fully contact the fabric fibers when penetrating the fabric.
Dye molecules gradually adhere to the surface of the fabric fibers and diffuse into the fibers in this contact process, relying on their own chemical properties and physical adsorption. After the dye passes through the warp beam, it will return to the dyeing tank. After heating or other treatment, it will circulate into the warp beam again. This process is repeated, so that the color of the fabric gradually deepens and achieves a uniform dyeing effect.
Bidirectional flow dyeing:
The dye can change its flow direction periodically, that is, it flows not only from the inside of the warp beam to the outside, but also from the outside to the inside. This bidirectional flow method can more effectively penetrate the dye into all parts of the fabric. Especially for thicker or tightly structured fabrics, bidirectional flow can overcome the uneven dyeing problem that may occur in unidirectional flow.
When the dye flows in the opposite direction, it will penetrate from the outer layer of the fabric to the inner layer, further ensuring that the inner and outer layers of the fabric can be dyed evenly. Moreover, bidirectional flow can make the pressure on the fabric during the dyeing process more uniform, reducing problems such as fabric deformation that may be caused by unidirectional pressure.
3. The role of temperature and auxiliaries
Temperature control principle: Temperature is a key factor in the dyeing process. The dyeing machine is equipped with a precise temperature control system to heat the dyeing liquid through a heating device. The temperature sensor monitors the temperature of the dyeing liquid in real time and feeds the signal back to the control system.
According to the set dyeing process requirements, the control system can accurately adjust the heating power to keep the dyeing liquid temperature within the appropriate range. Different dyes have different optimal dyeing temperatures. The appropriate temperature can improve the dye uptake and leveling of the dye.
Working principle of auxiliaries: Various auxiliaries are also added during the dyeing process, such as leveling agents, accelerators, buffers, etc. Leveling agents can make the dye evenly distributed on the fabric to avoid the situation where the local color is too dark or too light. Accelerators can increase the affinity of dyes to fabrics and improve the dye uptake. Buffers are used to stabilize the pH value of the dye solution, because changes in pH will affect the chemical properties of the dye and the dyeing effect. These auxiliaries will circulate in the system with the dye solution and play a corresponding role in the fabric dyeing process.
