This model uses immersion dyeing, steam heating and high-pressure structure for hank yarn containing polyester components. Compared with regular normal temperature hank dyeing, it supports higher dyeing temperature. Compared with GSH spray type high temperature hank dyeing machine, it focuses more on yarn roundness, hank shape and final appearance.
This machine is not a universal choice for every hank yarn project. It is more suitable for dyeing factories with experienced operators and dyeing technicians, because immersion dyeing requires careful control of yarn loading, temperature ramping, circulation condition and dyeing time.
| Recommended For | Not Recommended As First Choice |
|---|---|
| Polyester blended hank yarn | Yarn that does not require high-temperature dyeing |
| Yarn requiring better roundness, fuller hank shape and soft appearance | Regular hank yarn where appearance requirement is not strict |
| Small lot production and special yarn orders | Large batch production focused mainly on output efficiency |
| Dyeing factories with skilled operators and technicians | Factories needing simpler operation and stronger process standardization |
| Machine Type | Immersion type high temperature high pressure hank yarn dyeing machine |
|---|---|
| Batch Capacity | 5 kg |
| Dyeing Method | Immersion dyeing |
| Suitable Yarn | Polyester blended hank yarn and special hank yarn requiring better roundness after dyeing |
| Max. Design Working Temperature | 140°C |
| Recommended Actual Process Temperature | Usually adjusted up to about 138°C according to yarn material and dyeing recipe |
| Design Pressure | 4.4 bar |
| Normal Operating Pressure | 4 bar |
| Main Tank Safety Relief Valve Setting | 4.2 bar |
| Internal Heating Coil Pressure | 5.3 bar |
| Heating Method | Steam heating |
| Voltage / Power Supply | 380V, 50Hz |
| Main Material | Main dye liquor contact parts are made of 316L stainless steel |
| Main Pump Motor | Equipped with inverter for circulation adjustment |
| Standard Control System | Semi-automatic control with HG dyeing computer for temperature ramping |
| Optional Control System | Fully automatic control system or SEDO dyeing controller can be customized |
| Loading Form | Hank yarn is threaded onto hank hanging rods first, then loaded rods are placed into a customized yarn carrier |
Hank yarn is first threaded onto hank hanging rods. After loading, rods are placed into a customized yarn carrier designed for immersion dyeing under high temperature and pressure.
Proper loading is important for this machine. It helps keep hank yarn arranged during dyeing and supports better control of yarn shape, dye liquor contact and final appearance.
This machine uses steam heating. Max. design working temperature is 140°C, while actual process temperature is usually adjusted according to yarn material and recipe. Normal operating pressure is 4 bar, and design pressure is 4.4 bar.
Main tank safety relief valve setting is 4.2 bar. Internal heating coil pressure is 5.3 bar. Final pressure setting and machine configuration should be confirmed according to confirmed design and customer process requirements.
Main dye liquor contact parts are made of 316L stainless steel. The main pump motor is equipped with inverter, allowing circulation adjustment according to yarn condition and dyeing process.
In immersion dyeing, hank yarn stays immersed in dye liquor during processing. This method gives gentler treatment to yarn structure compared with stronger spray circulation.
For polyester blended hank yarn or special yarn requiring better roundness, fuller hank shape and softer appearance, immersion type design can be suitable when loading, temperature, circulation and dyeing time are controlled properly.
Both immersion type and GSH spray type high temperature hank dyeing machine can be used for polyester hank yarn dyeing, but selection logic is different. Immersion type is selected for yarn appearance and roundness. GSH spray type is usually better for easier operation and stronger process standardization.
| Selection Point | Immersion Type Machine | GSH Spray Type Machine |
|---|---|---|
| Dyeing Method | Immersion dyeing | Spray circulation dyeing |
| Best Fit | Polyester blended yarn and special yarn requiring better roundness | Regular polyester hank yarn requiring easier process standardization |
| Main Advantage | Better for hank shape, yarn roundness and special yarn appearance | Easier operation, stronger standardization and more convenient production management |
| Operator Requirement | More suitable for factories with experienced dyeing technicians | More suitable when customer wants simpler operation control |
| Selection Suggestion | Choose it when yarn appearance and roundness are key requirements | Choose it when regular polyester hank dyeing and stable operation are more important |
Standard configuration is semi-automatic control with HG dyeing computer. Temperature ramping can be controlled by dyeing program, while operators manage key process steps according to recipe and production condition.
SEDO controller is available as optional configuration. Fully automatic control can also be customized according to automation requirement, factory operation habit and customer dyeing process.
Actual dyeing program should be set by dyeing technician according to yarn material, dyestuff, shade depth and required final appearance.
If yarn does not contain polyester components or does not need high-temperature dyeing, a normal temperature hank dyeing machine may be more economical.
If customer mainly needs easier operation and higher standardization for regular polyester hank dyeing, GSH spray type high temperature hank dyeing machine may be more suitable. Final selection should be based on yarn material, batch capacity, dyeing temperature, yarn appearance requirement and operator experience.
Not sure whether to choose immersion type high pressure hank yarn dyeing machine, GSH spray type high temperature hank dyeing machine or normal temperature hank dyeing machine? We can review yarn material, batch capacity, dyeing temperature and appearance requirement before recommending suitable configuration.
It is suitable for polyester blended hank yarn and special hank yarn requiring better roundness, fuller hank shape and soft appearance after dyeing.
Max. design working temperature is 140°C. Actual process temperature is usually adjusted up to about 138°C according to yarn material and dyeing recipe.
Design pressure is 4.4 bar, normal operating pressure is 4 bar, and main tank safety relief valve setting is 4.2 bar. Final settings are subject to confirmed machine configuration.
Hank yarn is threaded onto hank hanging rods first. Loaded rods are then placed into a customized yarn carrier for immersion dyeing.
Standard configuration uses HG dyeing computer for temperature ramping. SEDO controller is available as optional configuration.
Standard configuration is semi-automatic control. Fully automatic control can be customized according to customer requirements.
Choose immersion type when yarn contains polyester components and final yarn roundness, hank shape and soft appearance are more important. Choose GSH spray type when regular polyester hank dyeing, easier operation and stronger standardization are more important.
This model is more suitable for small lot production, trial dyeing and special yarn orders. For larger regular production, higher capacity models or GSH spray type machines can be considered.
