Our high temperature high pressure liquid flow dyeing machine for woven fabric is an upgraded professional textile dyeing equipment built for high-yield, energy-saving, and defect-free fabric dyeing. Featuring a full floating fabric transmission design, the fabric suspends completely inside the liquid-filled fabric guide tube without any friction against the inner tube wall. With an ultra-high running speed ranging from 500m/min to 700m/min, the machine effectively eliminates fabric fuzzing, surface abrasion, and hairiness issues that commonly occur in traditional high-speed dyeing processes.
Equipped with a unique wave-type inner net structure, the system minimizes fabric resistance and ensures ultra-smooth continuous operation while greatly reducing water consumption. It supports an ultra-low liquid ratio of 1:5 to 1:6, adjustable according to different fabric types and technical process requirements, delivering outstanding high-efficiency and water-saving performance for modern textile production lines.
Working Principle
After being lifted by the fabric lifting reel, the fabric is entrained by the rapidly circulating dye liquor and propelled through a nozzle into the dye vat (or fabric guide tube). Driven by the liquor flow, the fabric accumulates in an orderly manner and moves slowly in a rope-like form within the vat, circulating repeatedly to complete the dyeing process. The relative movement between the liquor flow and the fabric ensures uniform dye penetration into and onto the fibers

Feature
Professional Structural Features | Downward-Travel Double-Barrel Design
This high temperature high pressure liquid flow dyeing machine for woven fabric adopts a mature downward-travel structural design with a standard configuration of two barrels, one cloth per barrel. The reasonable one-barrel-one-cloth independent circulation mode makes fabric operation more stable and tension-balanced. It features strong universality and is suitable for dyeing all types of conventional and high-grade fabrics, covering mainstream textile materials in the market with flexible and adaptable production performance.
Ultra-Large Capacity & Fast ROI Production
Designed with a large-diameter single barrel of Φ830, this double-barrel dyeing system effectively increases single-batch fabric loading capacity compared with ordinary small-caliber dyeing machines. The enlarged barrel space optimizes fabric circulation status and improves single-shift production output significantly. With ultra-large processing capacity and stable continuous operation, the equipment greatly boosts overall production efficiency and helps factories achieve fast investment return and higher economic benefits.
1:5~1:6 Ultra-Low Liquid Ratio | Energy Saving & Emission Reduction
Adopting an innovative wave-plate downhill fabric storage tank structure, the machine realizes an ultra-low liquid ratio of 1:5~1:6. This advanced low-bath-ratio design drastically reduces the consumption of water, industrial steam, and dyeing auxiliaries during mass production. It effectively cuts operational costs, lowers sewage discharge and carbon emissions, and meets international green textile and low-carbon manufacturing standards.
Optimized Cylinder Inner Mesh & Tapered Tail Inner Mesh Structure
This dyeing system is equipped with a special cylinder inner mesh plate and tapered tail inner mesh. The uniquely arranged mesh holes realize effective separation of fabric flow and dye liquor flow, supporting stable ultra-low liquid ratio operation. The professional tapered tail inner mesh ensures smooth fabric folding and uniform stress circulation. It achieves fast, balanced dye liquor circulation throughout the tank, avoiding local color difference and improving overall dyeing consistency.
Wide Fabric Compatibility with Dual Anti-Rotation Nozzles
Fitted with dual anti-rotation device nozzles, the machine supports switchable pressure modes to adapt to different fabric characteristics, covering stretch fabrics, high-density fabrics, and ultra-fine fiber fabrics.
Overflow Nozzle (0.5~1.0KG/cm²): Provides low spray pressure and low-tension dyeing environment, perfectly suitable for elastic and stretch fabrics. It prevents fabric stretching, deformation, and curling, protecting the original elasticity and soft handfeel of stretch textiles.
Jet Nozzle (Max 3KG/cm²): Delivers strong dye liquor penetration power, ideal for high-density woven fabrics and ultra-fine fiber materials. It solves poor dye penetration and shallow coloring problems, ensuring full and uniform dyeing for compact and fine textiles.
High Efficiency & Superior Uniform Dyeing Quality
The optimized double-cylinder circulation design shortens fabric circulation time and increases dye liquor circulation frequency significantly. It realizes full-process fast fabric feeding, rapid dyeing reaction, and efficient two-way fabric discharging. The high-frequency liquor circulation ensures full contact between fibers and dyes, greatly improving dyeing uniformity, color fastness, and batch stability. It effectively reduces defective rates and rework costs while maximizing production efficiency.
