The JF-O Series High Temperature And High Pressure Small Liquor Ratio Dyeing Machine is a next-generation efficient and environmentally friendly overflow dyeing machine developed by integrating advanced foreign design concepts. Focusing on low liquor ratio, large capacity, and high-speed operation, this equipment innovatively adopts a new nozzle system and fabric lifting & diffusion system, which significantly increases cloth loading capacity and fabric running speed while reducing the liquor ratio to an ultra-low level. It ensures uniform dyeing effect and excellent fabric hand feel, making it an ideal choice for dyeing most knitted and woven fabrics such as cotton, polyester, TC, TR, polyester blends, and jersey. With its outstanding energy-saving and consumption-reducing performance, the JF-O series has become a core equipment for printing and dyeing enterprises pursuing green and efficient production.
Equipped with a high-performance circulation structure, the JF-O dyeing machine achieves a fabric running speed of up to 420 meters/minute. Combined with an efficient cloth-liquid separation system, it realizes rapid double circulation of dye liquor and fabric. The uniform dye liquor penetrates the fabric at high frequency, completely solving the problem of uneven dyeing and ensuring consistent coloration across the entire batch of fabrics. This feature is particularly critical for large-scale production that requires strict color consistency.
The machine adopts a patented combination design of cloth swing and cloth feeding tube. This unique structural design ensures smooth cloth feeding without leaving any lines on the fabric surface. The large swing amplitude allows the fabric to be neatly stacked after reciprocating swing, minimizing operational failures such as cloth jamming. Meanwhile, the simplified operation process reduces the learning cost for workers, improving production efficiency and stability.
The new curved design of the cloth storage trough, paired with tubular Teflon rods neatly arranged in a sieve shape at the bottom, not only increases the cloth capacity but also ensures smooth fabric operation. The trough also realizes secondary separation of water and cloth, promoting rapid reflux of dye liquor and achieving an ultra-low liquor ratio of 1:4.5~5. This ratio is close to that of airflow atomization dyeing machines, but the JF-O series supports a wider range of dyeing varieties, breaking the limitations of traditional low-liquor-ratio equipment. An optional preparatory cylinder with hot water function further enhances its practicality.
The integrated vertical high-efficiency and low-consumption heat exchanger is a core energy-saving component of the JF-O series. It provides maximum heating rate, facilitates the drainage of dye liquor and condensed water, avoids scale formation, and extends the service life of the equipment. As part of the dye liquor circulation pipeline, it integrates heating and cooling functions without storing water itself, which is conducive to reducing the liquor ratio. The vertical layout enables real-time drainage of condensed water and dye liquor, significantly shortening the time consumed by cold and hot conversion and reducing heat loss.
Compared with conventional O-type dyeing machines of the same specification (with a per-bin capacity of 200-250kg), the JF-O series achieves a per-bin capacity of 400-450kg. The ultra-large capacity not only improves production efficiency but also reduces cylinder differences in batch dyeing, ensuring consistent quality between different production batches. It also accelerates the return on investment for enterprises.
The JF-O series has wide adaptability, suitable for dyeing most knitted and woven fabrics, including cotton, polyester, TC, TR, polyester blends, jersey, and other common fabrics in the printing and dyeing industry.
The ultra-low liquor ratio significantly reduces the consumption of water, dyes, salts, and auxiliaries, lowering production costs. At the same time, it is closer to the liquor ratio of airflow atomization dyeing but supports more dyeing varieties, balancing economy and versatility.
The combination of a 420m/min high fabric speed, efficient cloth-liquid separation system, and high-frequency dye liquor penetration ensures that every part of the fabric is in full contact with the dye liquor. The patented cloth swing design also avoids fabric entanglement, further improving dyeing uniformity.
