Overview


The JF-MX High-temperature And High-pressure Dyeing Machine is a cutting-edge overflow dyeing machine developed by integrating advanced domestic and foreign design concepts with over a decade of printing and dyeing industry experience. As a new-generation large-capacity, high-efficiency, and environmentally friendly equipment, it redefines the standards of fabric dyeing by balancing productivity, quality, and energy conservation. Suitable for both woven cloth and knitted cloth, including terry cloth, cotton elastic fabric, polar fleece, and spiral viscose elastic fabric, this machine caters to the diverse needs of modern textile manufacturers. With two models (JF-MX-1 and JF-MX-2) offering different loading capacities, it provides flexible options for small to large-scale production, ensuring excellent dyeing uniformity, low operating costs, and high processing efficiency.

Product Features


Wide Fabric Compatibility

The JF-MX series stands out for its versatile application scope, accommodating general knitted fabrics and the latest elastic fabrics. Whether it’s polyester elastic fabric, nylon elastic fabric, or thick terry cloth, the machine delivers consistent dyeing results. The weight range of applicable fabrics spans 50-600g/㎡, covering thin to medium-thick materials, making it a one-stop solution for textile factories with diverse product lines.


Dual Water Flow Modes

Equipped with both overflow water flow and jet water flow functions, the machine adapts to different fabric characteristics. By simply replacing the nozzle, users can switch between low-pressure, large-volume pure overflow flow (ideal for delicate elastic fabrics) and high-pressure, high-speed pure jet flow (suitable for dense woven fabrics). This dual-mode design ensures optimal dye penetration and color fastness for every fabric type.


Low Tension & Wrinkle-Free Dyeing

The composite variable diameter cloth guide tube is a core design that minimizes fabric tension during processing. This effectively eliminates radial creases, a common issue in traditional dyeing machines, and ensures the fabric maintains its original elasticity and shape. Additionally, the machine’s low height and moderate cloth length contribute to low post-dyeing shrinkage, helping manufacturers achieve the desired finished product weight with ease.


Energy-Saving Low Liquor Ratio

Boasting an ultra-low liquor ratio of 1:6, the JF-MX High-temperature And High-pressure Dyeing Machine significantly reduces water, dye, and energy consumption compared to conventional models. This not only cuts operational costs but also aligns with environmental protection requirements, making it a sustainable choice for modern textile enterprises.


Easy Operation & Maintenance

The short cloth groove design simplifies daily operation and maintenance. With intuitive controls and accessible components, the machine reduces downtime for cleaning and repairs, enhancing overall production efficiency. Even for new operators, the user-friendly interface ensures quick mastery of the dyeing process.


Mechanism Design


Lengthened Main Cylinder

The machine features a φ1100mm lengthened main cylinder with a body length of 8700mm and a thickness of 4mm, providing ample space for large-capacity dyeing. The extended cylinder design ensures uniform fabric movement and dye distribution, avoiding color differences caused by uneven contact between fabric and dye liquor.


Original Caterpillar Nozzle

The original caterpillar nozzle is engineered for high-performance water flow control. It works in tandem with the external cloth pipe to deliver stable and adjustable water flow, whether in overflow or jet mode. The nozzle’s durable construction ensures long-term reliability, even under high-temperature and high-pressure operating conditions.


Efficient Heat Exchanger

Equipped with a heat exchanger with a large heating area (10m² for JF-MX-1 and 14m² for JF-MX-2), the machine achieves a heating rate of 3℃/min and a cooling rate of 2.5℃/min. This rapid temperature adjustment capability allows for precise control of the dyeing process, ensuring consistent results across batches.


High-Pressure Resistant Structure

Designed to withstand a maximum temperature of 135℃ and a maximum pressure of 0.4Mpa, the machine’s robust structure (including a φ1000mm machine head) ensures safe and stable operation under extreme conditions. The pressure-resistant design also extends the machine’s service life, reducing long-term investment costs.


FAQ


What fabrics can the JF-MX dyeing machine process?

The machine is suitable for a wide range of fabrics, including woven cloth, knitted cloth, terry cloth, cotton elastic fabric, polar fleece, spiral viscose elastic fabric, polyester elastic fabric, and nylon elastic fabric. It accommodates fabric weights from 50-600g/㎡.


What is the maximum temperature and pressure of the machine?

The maximum operating temperature is 135℃, and the maximum working pressure is 0.4Mpa, making it suitable for high-temperature dyeing processes required by synthetic fabrics.


How does the dual water flow mode work?

By replacing the nozzle, the machine can switch between overflow water flow (low-pressure, large-volume) and jet water flow (high-pressure, high-speed). This allows users to optimize the dyeing process for different fabric types.


How often does the machine require maintenance?

Routine maintenance (e.g., cleaning the cloth guide tube, checking the nozzle, and replacing filters) is recommended every 15-20 working days. Major maintenance (e.g., inspecting the heat exchanger and motor) can be performed annually, depending on usage frequency.


Can the machine achieve consistent finished product weight?

Yes. The low-tension design, moderate cloth length, and precise process control ensure minimal post-dyeing shrinkage, making it easy to achieve the desired finished product weight.
