Eco-Friendly High-Efficiency Dyeing System | Low Liquor Ratio HT Overflow Machine for Knitted Fabrics
Modern textile dyeing pursues both superior finishing quality and eco-friendly energy-saving production, and our low liquid ratio high-speed dyeing system perfectly meets this dual demand. As a ht jet dyeing machine for knitted fabric dedicated to knitted fabric dyeing, it revolutionizes traditional dyeing processes with low consumption, high efficiency and high-precision dyeing capabilities, helping textile enterprises reduce costs and boost productivity.
Different from conventional dyeing equipment that causes severe fabric friction and easy fuzzing, this advanced dyeing machine features a full-liquid floating operation mode. Knitted fabrics run suspended in the liquid-filled guide tube without wall friction, supporting a stable running speed of 300-500m/min. The high-speed and low-friction operating mode fundamentally inhibits fabric fuzzing, ensuring neat, smooth and flawless fabric surfaces after dyeing, suitable for high-standard knitted fabric production.
Featuring high-speed operation, low liquor ratio water saving, low friction and zero pilling, our ht jet dyeing machine for knitted fabric system reduces water resource waste, lowers dye and auxiliary consumption, and improves overall production efficiency. It is a cost-effective, eco-friendly and high-quality dyeing solution for mass production of various knitted fabrics, widely applicable to medium and large textile dyeing workshops worldwide.
Working Principle
The HT jet dyeing machine operates based on the Venturi effect: the dye liquor is pressurized by a circulation pump and ejected from a nozzle at high speed (500–1,400 m/min), creating a powerful flow that propels the rope-form fabric through the transport tube at high speed (200–800 m/min). After exiting the transport tube, the fabric enters the storage chamber and accumulates in a relaxed state before being fed back into the jet system, establishing a continuous cycle.
The dye liquor circulates every 30–60 seconds with precise temperature control via a heat exchanger, while the fabric completes a full cycle every 1–2 minutes, ensuring uniform dyeing and preventing crease formation caused by prolonged stationary periods.
Product Features
Our ht jet dyeing machine for knitted fabric adopts an advanced upward-travel design with an external cloth guide tube, delivering exceptional adaptability for full-range high-end knitted fabric dyeing. Supporting fabric weights from 50g/m to 600g/m, this versatile dyeing equipment handles ultra-light thin knits to heavy-weight knitted materials with stable and reliable dyeing results, making it the ideal solution for diverse high-end textile production demands.
Engineered with an industry-leading ultra-low liquor ratio system, the machine achieves an optimal liquid ratio of 1:6 to 1:8. Fitted with a sloped bath tank structure, it easily accommodates high-volume liquid processing requirements for complex dyeing crafts. Adopting an N-type forward fabric conveying method, the equipment completely eliminates rope-shaped curling creases. Fabrics operate at high speed under ultra-low tension status, significantly enhancing overall dyeing uniformity and finishing consistency for every batch of textiles.
Designed with ultra-large processing capacity, this ht jet dyeing machine for knitted fabric operates with low spray pressure and high-volume liquid circulation. The unique fluid circulation system allows fabrics to advance in a relaxed stacked state throughout the dyeing process. This humanized structural design effectively prevents common textile defects including lint formation, yarn cracking and fabric scratching, ensuring intact and smooth fabric surface quality after dyeing treatment.
Focusing on energy-saving and cost reduction, the equipment features ultra-low overall energy consumption. Compared with traditional old-generation dyeing machines, it saves up to 30% on water, electricity, steam and dye auxiliaries, greatly cutting down production operating costs. Meanwhile, its effective processing capacity is increased by approximately 30%, realizing dual improvements in production efficiency and economic benefits.
Equipped with multiple patented innovative technologies, including a newly patented cloth tank and composite cloth guide structure, the machine integrates a tail-end gasification fabric finishing function. The innovative dual-strip rapid circulation technology enables fast and stable running of ultra-light and thin knitted fabrics, solving the long-standing processing difficulties of thin fabric dyeing and bringing highly efficient and innovative production advantages to modern textile dyeing workshops.
