This ht jet flow dyeing machine is designed for low liquor ratios, high speeds, and high efficiency, employing a fully immersed fabric guide tube.
The fabric floats within the guide tube, eliminating internal wall friction, and can travel at speeds of 300–500 meters per minute, thus reducing pilling and fuzzing.
Its unique corrugated inner mesh structure reduces friction, ensuring stable operation and minimizing water consumption.
The liquor ratio can be adjusted according to fabric and process requirements, from a minimum of 1:6–8.

Core Structure
Dyeing Chamber
Sealed high-pressure cylinder, made of 316L stainless steel, with strong pressure resistance and corrosion resistance.
Spraying System
Adjustable rectangular/circular nozzles for precise control of dye liquor spraying pressure and flow rate.
Fabric Guiding System
Variable frequency guided fabric roller + square/circular fabric guide tubes, allowing the fabric to run in a relaxed state, with low tension to prevent damage.
Circulation System
High-efficiency stainless steel centrifugal pump to ensure high-speed circulation and uniform distribution of dye liquor.
Temperature Control System
Built-in high-efficiency heat exchanger for precise temperature control (±0.5℃), with adjustable heating/cooling rates.
Control System
PLC + touch screen for fully automatic process control, supporting the storage of multiple process formulas.
Working Principle
The HT jet flow dyeing machine uses a nozzle to spray dye solution at high speed, which drives the fabric in a rope-like motion. The fabric circulates within the main cylinder and is fully penetrated and impacted by the dye solution. Under high temperature (typically up to 140℃) and high pressure, dye molecules can diffuse and fix onto the fiber more quickly, making it particularly suitable for synthetic fibers such as polyester that require a high-temperature carrier.
Advantages
Key Structural Advantages
Upward feed type with external cloth guide tube, perfect for premium knitted fabrics 50–600g/m.
Ultra-low Liquor Ratio
Liquor ratio as low as 1:6–1:8 with sloped bath.N-type cloth path avoids rope marks; low-tension high-speed operation greatly improves dyeing evenness.
Super High Capacity
Large batch capacity, low spray pressure and strong liquid circulation.Fabrics run smoothly and loosely, preventing pilling, snapping and scratching.
High Energy Saving
Reduces consumption of water, electricity, steam and chemicals.Costs cut by about 30% and capacity boosted by around 30% vs. traditional machines.
Innovative Patented Technologies
New patented tank, multi-structure cloth guide and gas-assisted cloth delivery enable fast two-strand running for light fabrics, bringing high efficiency and advanced performance.
