Overview


The JF-JNG500 High-Temperature Ultra-Low Liquor Ratio Dyeing Machine is a revolutionary jet-type dyeing machine designed for high-efficiency, energy-saving fabric processing. With a maximum running speed of 500 meters/minute, it sets a new benchmark for productivity in the textile industry. Built on the premise of ultra-low liquor ratio, this machine prioritizes energy conservation while ensuring stable processing and superior dyeing quality. It is specifically engineered for wrinkle-prone fabrics and sensitive fabrics such as polyester aramid, nylon aramid, and other warp-knitted and woven products, as well as a wide range of high-grade, high-value-added fabrics from thin to thick. Available in three models (JF-JNG500-I, JF-JNG500-II, JF-JNG500-V) with varying loading capacities, the JF-JNG500 series meets the demands of small-batch customization and large-scale mass production alike.

Product Features


High-Speed Operation

With a running speed of up to 500m/min, the JF-JNG500 series significantly shortens processing time, doubling productivity compared to conventional dyeing machines. This high-speed design is particularly beneficial for large-volume orders, helping manufacturers meet tight delivery deadlines without compromising quality.


Ultra-Low Liquor Ratio for Energy Savings

As an ultra-low liquor ratio dyeing machine, it operates with a liquor ratio of approximately 1:6, minimizing water, dye, and chemical usage. This not only reduces operational costs but also reduces wastewater discharge, aligning with green production standards and sustainable development goals.


Low-Tension Loose Fabric Dyeing

The machine features a free low-tension running area where fabrics maintain the best loose state throughout the dyeing process. This design eliminates creases and damage to sensitive fibers, ensuring the fabric’s softness, elasticity, and appearance are preserved. It is the ideal choice for dyeing high-value fabrics that require strict quality control.


Programmable Temperature Control

Equipped with a temperature program controller, users can set precise heating, insulation, and cooling rates according to different fabric dyeing processes. This ensures consistent dyeing results across batches, reducing human errors and improving product quality stability.


Wide Fabric Adaptability

From thin high-grade fabrics to thick woven products, the JF-JNG500 can process a diverse range of materials. It is especially suitable for high-value-added fabrics such as polyester aramid and nylon aramid, which are prone to wrinkling and require gentle processing.


Simple Structure & Easy Operation

The machine's reasonable design and simple structure make it easy to operate and maintain. Compared to similar products, it has lower energy consumption and larger output, providing excellent cost-performance for textile enterprises.


FAQ


What is the maximum running speed of the JF-JNG500?

The machine’s maximum running speed reaches 500 meters/minute, making it one of the fastest dyeing machines in the market, significantly improving production efficiency.


Which fabrics are most suitable for this machine?

It is specifically designed for wrinkle-prone fabrics and sensitive fabrics such as polyester aramid, nylon aramid, warp-knitted products, and woven products. It also processes high-grade, high-value-added fabrics from thin to thick.


How does the machine prevent fabric wrinkles?

The free low-tension running area keeps fabrics in a loose state throughout the dyeing process, minimizing friction and pressure. This design eliminates creases and preserves the fabric’s original texture and appearance.



Mechanism Design


Horizontal Tubular Structure

The JF-JNG500 adopts a horizontal tubular design, which ensures smooth fabric movement and uniform dye liquor circulation. The horizontal layout reduces fabric tension and prevents tangling, making it suitable for long-length fabric processing.


High-Power Main Pump

Equipped with a strong main pump, the machine delivers sufficient dye liquor flow to ensure rapid and uniform dye penetration. The pump’s high-performance design supports the machine’s high-speed operation, maintaining stable water flow even at 500m/min.


Large-Area Heat Exchanger

The heat exchanger features a large heat transfer area, enabling rapid temperature adjustment and precise control. This ensures the dyeing process stays within the set temperature range, enhancing color fastness and consistency.


Free Low-Tension Running Zone

The dedicated low-tension running area is designed to keep fabrics in a loose state, avoiding friction and pressure that cause wrinkles. This mechanism is crucial for processing sensitive and wrinkle-prone fabrics, ensuring the final product meets high-quality standards.
