The high temperature jet flow dyeing machine is designed with a gentle slope structure connecting to a multi-functional liquid distribution tank, combining the advantages of both O-type and L-type dyeing tanks. It not only achieves the low liquor ratio characteristics of an O-type dyeing tank, but also supports a variety of fabrics like an L-type dyeing tank, while overcoming the disadvantages of a narrow range of applicable fabrics and high water consumption.

Working Principle
The core principle of a high-temperature jet flow dyeing machine is to relax the fabric in a high-temperature, high-pressure dyeing solution, and then use the jet force of a high-speed liquid flow to move the fabric (jetting), while the dye solution gently permeates the fabric through an overflow port (overflow), allowing the dye solution and fabric to come into full and uniform contact in a short time, thus achieving rapid dyeing.
Main Structural Components
Dyeing Vat System
Main vat body is made of 316L stainless steel, offering strong corrosion resistance.
Double-jacket structure design provides excellent heat insulation.
Fabric storage tank is equipped with Teflon (polytetrafluoroethylene) sliding plates to reduce fabric wear.
Spraying and Circulation System
JTZ dual-stage adjustable nozzles: adaptable to fabrics of different thicknesses.
High-efficiency centrifugal pump: high flow rate, low head, variable frequency soft start.
Automatic cleaning filter: prevents dye particle clogging.
Heat Exchange System
Plate or tubular heat exchangers for high heating/cooling efficiency.
Indirect steam heating with temperature control accuracy ±1°C.
Intelligent Control System
Touchscreen PLC control: programmed dyeing process management.
Automatic metering and feeding system: proportional heating and quantitative feeding.
Fabric speed sensor: real-time monitoring of fabric operating status.
Remote monitoring interface: supports data acquisition and production optimization.
Features
1. Large Capacity, High Efficiency
Utilizing a Φ1108 single-pipe diameter, internal dual-storage tank, and dual-nozzle design, it significantly increases fabric loading capacity and processing efficiency, ensuring a rapid return on investment.
2. Low Liquor Ratio 1:5~1:6, Energy Saving and Emission Reduction
The new gentle slope structure and multi-functional fabric storage tank allow for liquor ratios of 1:5 to 1:6 (adjustable according to fabric type and process), significantly reducing water, steam, and chemical consumption.
3. Wide Applicability
Equipped with overflow nozzles operating at 0.5~1.0 kg/cm², suitable for elastic fabrics and materials requiring low-pressure, low-tension dyeing.
Spray nozzles with pressures up to 3.0 kg/cm² are suitable for high-density and microfiber fabrics. Dual anti-twist nozzles are standard.
4. High-Efficiency Dyeing, Superior Quality
The single-pipe dual-dye tank design shortens fabric cycle time, increases dyeing cycle frequency, and enables rapid feeding, rapid dyeing, and bidirectional rapid discharge. This greatly improves production efficiency and ensures uniform dyeing results.
Advantages
1. Improved dyeing quality and better colorfastness.
2. Saves energy and water resources, meeting green environmental protection requirements.
3. Simple operation, high degree of automation, reducing manual intervention.
4. Highly adaptable, meeting the dyeing needs of different types of fabrics.
