The HTHP jet flow dyeing machine employs ultra-low liquor ratio high-speed dyeing technology. The fabric is suspended within a dye-filled guide tube, without contact with the tube wall, and operates at speeds of 300-500 meters per minute, effectively preventing pilling. Its unique wave-shaped inner mesh structure significantly reduces fabric running resistance, resulting in smoother fabric movement. Simultaneously, this design significantly reduces water consumption, with a liquor ratio as low as 1:6 to 1:8, which can be flexibly adjusted according to fabric type and process requirements.

Working Principle
The HTHP jet flow dyeing machine generates high-pressure dye liquor through a main pump, which is then sprayed onto the fabric through nozzles. Simultaneously, the nozzles utilize the force of the liquid flow to propel the fabric forward, creating a combined "jet" and "overflow" effect. The fabric is dyed under tension-free conditions, ensuring excellent hand feel and dimensional stability.

Features
1. Top-running fabric structure: Built-in fabric guide tube design, suitable for a wide range of fabric weights (50g/m² - 800g/m²), perfectly compatible with various high-end knitted fabrics.
2. Low-tension, high-flow system: Employs low-pressure, high-flow nozzles to effectively reduce fabric running tension, minimize fuzz and yarn breakage, while improving fiber swelling and dyeing uniformity.
3. Anti-wrinkle and expansion device: Equipped with a fabric expander, allowing the fabric to fully expand during the buffering process and continuously change shape in the dye bath, effectively preventing creases and curling.
4. Intelligent operating system: High-precision fully automatic computer control, supports DOSING automatic feeding, and features an efficient inlet and outlet drainage system; an optional preparatory tank can be added for heat recovery, reducing operating costs.
5. Precise speed control: High-performance variable frequency stepless speed regulation ensures perfect matching of fabric speed and process time at any speed range, eliminating fabric defects caused by speed asynchrony.
