Description

The Low Liquor Ratio jet flow Dyeing Machine is designed as a low-liquor-ratio, high-speed, and high-efficiency dyeing system.

The fabric floats within a liquid-filled conduit, avoiding contact with the conduit walls.

The operating speed is 300 to 500 meters per minute, minimizing pilling and fuzzing.

A special corrugated inner mesh reduces fabric friction, improves running smoothness, and conserves water.

An optimized tail slip structure enables ultra-low liquor ratios of 1:5 to 6 (the specific ratio depends on the fabric and process selection).

Working Principle

The Low Liquor Ratio jet flow Dyeing Machine mainly consists of a dyeing tank, nozzles, a fabric guiding system, a circulation pump, a heat exchanger, and a control system. Under the action of the circulation pump, the dye liquor is pressurized and ejected at high speed from specially designed nozzles, forming a powerful jet. Driven by the jet, the fabric circulates rapidly within the dyeing tank, ensuring thorough contact and exchange with the dye liquor, thus achieving uniform dyeing. The low liquor ratio design (typically 1:4 to 1:8) reduces the amount of dye liquor used, improving dye utilization and dyeing efficiency.

Product Features

Structural Advantages

Upward-feed type with external cloth guide tube and slide design, perfect for dyeing premium knitted fabrics ranging from 50g/m to 600g/m.

Ultra-low Liquor Ratio

Liquor ratio lowered to 1:5–1:6 with sloped tank for high-liquid processes. N-type cloth feeding eliminates rope creases; low-tension high-speed operation greatly improves dyeing uniformity.

Ultra-high Capacity

Generous capacity, low spray pressure and strong circulation. Fabrics run in a relaxed, layered state with zero pilling, yarn breakage or surface defects.

High Energy Efficiency

Low energy consumption cuts water, electricity, steam and chemical costs by about 30% compared with older machines, while increasing productivity by around 30%.

Advanced Innovative Technologies

Patented cloth trough, multi-functional cloth guide system and tail gas finishing function allow dual-strip high-speed processing of lightweight fabrics, ensuring innovative and efficient performance.

Selection Recommendations

Liquor Ratio Verification

Pay attention to the process conditions under which the equipment's stated minimum liquor ratio is achieved (e.g., light or dark colors, cotton or synthetic fibers).

Fabric Compatibility

If you frequently dye sensitive fabrics (such as easily wrinkled microfiber fabrics), it is recommended to choose a model with independent speed control of the lifting rollers and a wide adjustable range of nozzle pressure.

Supporting Facilities

Low liquor ratio dyeing typically requires higher head and flow rate from the main pump to ensure rapid and uniform circulation of the dye liquor even with low water levels.
