| High-Temperature Vertical Hank Dyeing Machine |
100–500 kg per machine |
Up to approximately 140°C |
Polyester, nylon, acrylic blends, and other synthetic yarns requiring pressurized dyeing. |
Vertical dyeing chamber: Holds the hank carriers and dye liquor.
Circulation pump: Moves dye liquor through the yarn packages or hanks.
Heat exchanger: Heats and cools the dye bath efficiently.
Lid-locking system: Maintains a sealed vessel during high-temperature operation.
|
Compact floor arrangement and good liquor circulation. Loading height and operator access should be considered when selecting the vessel size. |
| High-Temperature Horizontal Hank Dyeing Machine |
200–1,000 kg per machine |
Up to approximately 140°C |
Large production lots of synthetic yarn, blended yarn, and specialty hank-dyed materials. |
Horizontal pressure vessel: Provides a sealed dyeing space with convenient front or side loading.
Hank support frame: Keeps yarn loops separated for more uniform liquor contact.
Reversing circulation system: Alternates liquor-flow direction to reduce shade variation.
Drain and rinse circuit: Removes residual dye liquor and auxiliaries.
|
Suitable for higher batch volumes and easier loading access. The longer circulation path requires careful control of pump flow and hank arrangement. |
| High-Temperature Overflow Hank Dyeing Machine |
50–600 kg per chamber |
Typically 120–140°C |
Polyester and blended yarns where gentle handling and controlled liquor movement are important. |
Overflow nozzle or liquor inlet: Creates a smooth flow around the hanks.
Adjustable circulation pump: Controls liquor velocity and dye penetration.
Perforated hank carrier: Supports the yarn while allowing liquor to pass through.
Temperature and pressure sensors: Monitor safe and repeatable process conditions.
|
Provides relatively gentle mechanical action and can help limit yarn deformation. Flow settings must be matched to yarn count and hank density. |
| High-Temperature Package-and-Hank Combination Machine |
100–800 kg per batch |
Up to approximately 140°C |
Facilities processing both yarn hanks and wound packages, especially synthetic and blended yarns. |
Interchangeable carrier system: Accepts hank frames or package holders.
Programmable flow reversal: Changes the liquor direction for even dye penetration.
Separate loading fixtures: Maintain the correct geometry for each yarn form.
Recipe controller: Stores temperature, time, dosing, and flow settings.
|
Improves production flexibility and equipment utilization. Different yarn forms require separate loading procedures and optimized flow rates. |
| High-Temperature Multi-Chamber Hank Dyeing Machine |
4–16 chambers; 25–150 kg per chamber |
Up to approximately 140°C |
Multiple shades, smaller lots, sampling, and production environments requiring frequent color changes. |
Independent dyeing chambers: Allow different colors or recipes to run simultaneously.
Individual circulation circuits: Maintain separate liquor flow in each chamber.
Central dosing unit: Delivers dyes and auxiliaries according to the programmed recipe.
Isolation valves: Prevent cross-contamination between chambers.
|
Reduces waiting time for small and medium batches. More valves, pumps, and sensors require disciplined maintenance and calibration. |
| High-Temperature Sample Hank Dyeing Machine |
1–20 kg per batch |
Up to approximately 140°C |
Laboratory trials, shade approval, recipe development, and correction of production colors. |
Small pressure vessel: Reproduces high-temperature dyeing conditions at laboratory scale.
Precision dosing pumps: Add small quantities of dye and chemicals accurately.
Digital controller: Manages heating rate, holding time, cooling, and alarms.
Quick-drain and rinse system: Speeds up sample changeover.
|
Uses less water, dye, and energy during development. Laboratory recipes should be scaled carefully because liquor circulation and heat transfer differ from production machines. |
| Energy-Efficient High-Temperature Hank Dyeing Machine |
100–800 kg per batch |
Typically 120–140°C |
Production dyeing where reduced water, steam, and electricity consumption are priorities. |
Low-liquor-ratio vessel: Reduces the amount of water required for each batch.
Variable-frequency drive: Adjusts pump and motor speed to the actual process demand.
Heat-recovery exchanger: Transfers heat from hot effluent or cooling liquor to incoming water.
Automatic dosing system: Improves repeatability and limits chemical overuse.
|
Can lower utility consumption when the machine is correctly loaded and programmed. Lower liquor volume requires accurate dosing and reliable circulation control. |
| High-Temperature Air-Assisted Hank Dyeing Machine |
100–600 kg per batch |
Typically 120–140°C |
Lightweight synthetic yarns and applications requiring reduced liquor consumption and controlled yarn movement. |
Air injection system: Adds controlled air to support liquor circulation and yarn movement.
Air-liquid separator: Controls entrained air before the liquor returns to the pump.
Low-tension hank carrier: Helps minimize excessive yarn stretching.
Flow and pressure control: Maintains stable air and liquor conditions.
|
May reduce liquor demand and mechanical stress in selected processes. Air content must be controlled to avoid unstable flow or uneven wetting. |
| Common Safety and Automation System |
Applicable to all high-temperature types |
Designed for the selected process limit |
All yarns processed under elevated temperature and pressure conditions. |
PLC and human-machine interface: Controls recipes, sequences, alarms, and batch records.
Pressure relief valve: Protects the vessel against excessive internal pressure.
Door or lid interlock: Prevents opening while the vessel is pressurized.
Level sensor: Confirms the required liquor volume before circulation and heating.
Temperature probe: Provides feedback for accurate heating and cooling.
|
These systems are essential for safe operation, consistent shade reproduction, and traceable production. Sensors, valves, and interlocks should be inspected and calibrated regularly. |
