Compared with the traditional yarn dyeing machines, the outstanding advantages are:
1）GR202 adopts the most advanced mixed-flow pump(with high efficiency and high cavitation resistance performance of newest design currently in China. The forward and reverse circulation for dyeing is automatically executed by the directional valve in the pump. The impeller in the pump can provide large flow and sufficient head coefficient for the yarn dyeing process. Due to its strong penetrability, it is suitable for very difficult texture and various kinds of textures. The dyed texture is with high color fastness and uniform dyeing effects.
2）Full-flooded structure: GR202 is equipped with the feeding system (mixer and feeding barrel), pressurizing system (auxiliary pump), and circulation system (cooler). Thus the dyeing procedure could be completed to meet the process requirements under both normal temperature high pressure and high temperature high pressure conditions. GR202 has wide applicability and good dyeing quality.
3）High automation degree with good process repeatability and convenient operation. Since the machine is equipped with computer control system, the dyeing operation can be automated, which reduces the effects of human factors in manual operation. The dyeing procedure can be executed completely according to the process requirements. Each function and order can be controlled by the program of the electric system, thus the process is with repeatability and the differences between different cylinders are reduced.
4）Reasonable operating environment and high safety. GR202 adopts self-sealing cylinder seal, pneumatic cylinder locking interlocking safety device, and pneumatic cylinder opening & closing device. It is with convenient operation and is safety reliable. Each nozzle adopts a pneumatic-manual valve and the coil heating system inside the cylinder is automatically controlled. Hence, the labor strength is low and the operation environment is comfortable.
