Description

The new generation of high temperature airflow jet dyeing machines breaks through the multi-tube independent structure, optimizing single-tube load to achieve rapid dye liquor circulation, meeting the requirements for atomized liquid volume, high-frequency reflux, and penetration, thus conforming to process requirements. The equipment features neatly arranged fabric rings, preventing fabric tangling and compression. The entire machine adopts modular control and intelligent operation, achieving another innovative breakthrough in dyeing quality, output, and product variety expansion for high-temperature airflow jet dyeing machines.

Working principle

1. Airflow Driven System: A built-in blower generates high-pressure airflow, utilizing the Venturi effect to draw the dye liquor from the storage tank and atomize it.

2. Atomizing Spray: The airflow and dye liquor mix at the nozzle, forming a mist that is evenly sprayed onto the fabric surface.

3. Fabric Circulation: The fabric continuously circulates within the dyeing vat under the propulsion of the airflow, eliminating the need for extensive dye liquor soaking.

4. High-Temperature Treatment: The operating temperature can reach 130-150°C, suitable for high-temperature and high-pressure dyeing processes.

Core Advantages

Ultra-low liquor ratio, energy-saving and environmentally friendly

Liquor ratio can be as low as 1:1.5-2 for polyester fabrics and 1:3.5-4 for cotton fabrics.

Savings 10-15% on dyes, over 60% on auxiliaries, and approximately 60-70% on water, electricity, and gas consumption.

Wastewater discharge is reduced by over 60%, significantly lowering wastewater treatment costs.

Excellent dyeing quality

High evenness: The mist-like dye liquor has strong penetration, resulting in high fabric dye absorption and uniform dyeing.

No creases: The fabric operates under micro-tension, and the high-speed airflow reduces fabric tension, minimizing color variations and creases.

Good reproducibility: Automated control ensures batch-to-batch color consistency.

High production efficiency

Fast fabric running speed shortens dyeing process time. Rapid heating, feeding, and washing systems compensate for fluctuations in factory water and steam pressure.

One-pass dyeing success rate can reach 98%.
