The high temperature high pressure liquid flow dyeing machine is a dyeing system characterized by a low liquor ratio, high performance, and high efficiency. Within the liquid-filled fabric guide tube, the fabric stays afloat without any friction against the inner wall of the tube. It operates at speeds ranging from 500 to 700 meters per minute, effectively minimizing the occurrence of fuzzing. Its unique wave-shaped inner net structure further lessens fabric friction, ensuring smoother operation and reducing water usage. The liquor ratio can be as low as 1:5 to 1:6, with the specific ratio determined by the fabric type and process requirements.
Working Principle
The fabric is loaded into the dyeing chamber and immersed in the dye liquor. Under controlled high-temperature and high-pressure conditions, the dye liquor is pumped through the system, creating a directional flow that circulates the fabric. As the fabric passes through the dye liquor, the dye molecules are absorbed by the fibers. The circulation of the dye liquor ensures that fresh, uniform dye concentrations are constantly in contact with the fabric, while the high temperature and pressure enhance the dye's ability to bind to the fibers. After dyeing is complete, the pressure is released, and the fabric undergoes rinsing and drying, completing the dyeing process.
Product Features
Structural Characteristics
Featuring a downward-travel design, this equipment adopts a "one barrel for one cloth" configuration with two barrels in total, making it suitable for processing a wide range of fabric types.
Exceptional Capacity and Productivity
Each barrel features a large diameter of Φ830, which enhances fabric-holding capacity, significantly boosts production output, and ensures a rapid return on investment.
Low Liquor Ratio (1:5~1:6) for Energy and Emission Reduction
Equipped with a new wave-plate downhill structure and a specially designed cloth storage tank, the machine achieves a liquor ratio of 1:5~1:6, drastically reducing consumption of water, steam, and additives.
Special Inner Mesh Plates and Tapered Tail Mesh
The unique arrangement of inner mesh holes separates fabric flow from dye liquor flow, supporting the low liquor ratio. A specialized tapered inner mesh ensures smooth fabric folding and rapid, balanced circulation.
Versatile Fabric Compatibility
Overflow nozzles operate at pressures between 0.5~1.0KG/cm², suitable for dyeing stretch fabrics and materials requiring low spray pressure and tension. Jet nozzles, with a maximum pressure of 3KG/cm² (incorporating dual anti-rotation devices), are ideal for high-density and ultra-fine fiber fabrics.
High Efficiency and Quality
The dual-barrel design shortens fabric circulation time in the dye tank and increases dye liquor circulation frequency. This enables fast fabric feeding, rapid dyeing, and quick two-way discharge, greatly enhancing production efficiency and ensuring uniform dyeing quality.
Advantage
Faster Dyeing
High-temperature and high-pressure conditions accelerate dye penetration, thereby shortening the time required for each dyeing cycle.
Uniform Dyeing
The liquid flow system ensures uniform dye distribution throughout the fabric, resulting in consistent color across the entire batch.
Reduced Water and Dye Consumption
The continuous liquid flow system minimizes the need for large amounts of water and dye, making the entire process more environmentally friendly and cost-effective.
Improved Dye Quality
Enhanced dye penetration and color fixation result in more vibrant and durable colors, reducing the need for re-dyeing or touch-ups.
Cost Savings
By reducing water and energy consumption, as well as shortening dyeing times, manufacturers can achieve long-term operational cost savings.
Sustainability
The high temperature high pressure liquid flow dyeing machine efficiently utilizes resources and reduces environmental impact, making it a more sustainable option for textile production.
