Working Principle

1. Jet Drive: A high-speed dye liquor stream generated by the main pump is ejected through nozzles, and the jet thrust propels the fabric to circulate within the dye tube. This results in significantly lower fabric tension compared to overflow dyeing machines driven by guide rollers.

2. Uniform Stress: Due to the more uniform stress on the fabric, the dyed fabric has a softer hand feel, and the dyeing effect is superior to traditional overflow dyeing machines.

3. Operating Environment: Typically operates under high temperature and high pressure conditions, with a maximum operating temperature of 140-180°C and a maximum operating pressure of 0.36 MPa, which facilitates the rapid penetration of dye molecules into the fiber interior.

Structural Component

1. Dyeing Main Body: Stainless steel double-jacketed tank, pressure-resistant, heat-insulating, and corrosion-resistant.

2. Circulation System: Variable frequency centrifugal pump, heat exchanger, filter, nozzle assembly.

3. Fabric Conveying: Variable frequency guide rollers, fabric trough, guide tube, low-tension drive.

4. Temperature Control System: Pneumatic heating/cooling valve, high-precision temperature sensor, temperature control accuracy ±0.5℃.

5. Control System: PLC, touch screen, pressure/level/flow sensor, online monitoring module.

6. Auxiliary System: Feed pump, drain/overflow valve, safety pressure relief device, cleaning device.

Feature

High Efficiency

Flexible configuration for similar models, various types and specifications, with customized solutions to fully demonstrate production capacity advantages. It supports multi-tube rapid automatic fabric discharge in both vertical and horizontal directions.

Ultra-low Liquor Ratio

Full-load operation with a liquor ratio as low as 1:3–4 (fabric moisture not included).

Precise Control

Intelligent dyeing with fully automatic control, efficient washing programs and high reproducibility. Linear rapid temperature control minimizes shade deviation. Automatic lint collection and removal ensures stable nozzle spray pressure.

Energy Saving & Environmental Protection

Lower main pump suction port with self-cooling and lubrication, saving cooling water. Vertical heat exchanger enables instant condensate discharge, shortening heating/cooling cycles and preventing scaling.

Key Advantages

1. High Dyeing Uniformity: Optimized nozzle and circulation system design ensures consistent dye liquor distribution.

2. Energy Saving and Environmentally Friendly: Compared to traditional overflow dyeing machines, water consumption is reduced by approximately 30%-40%, and steam consumption is reduced by over 20%.

3. Wide Applicability: Can process various materials including knitted, woven, and elastic fabrics.

4. High Degree of Automation: Supports one-button start, automatic feeding, and temperature profile control, reducing manual intervention.
