Hthp overflow dyeing machine is a Low liquid ratio, high, high efficiency dyeing system. The fabric is in a floating state in the liquid-filled fabric guide tube, without friction with the inner tube wall, and the running speed reaches 300-500m/min, reducing the fuzzing phenomenon. The special "wave" type inner net structure speed reduces the friction of the fabric, running more smoothly and reducing water consumption, and the liquid ratio can be as low as 1:6~8 (select according to the fabric type and process requirements).
Product Features
Structural features
Upward-travel type, built-in cloth guide tube, suitable for dyeing various high-end knitted fabrics with a fabric weight range of 50g/m-800g/m.
01
Low tension, high flow
The low-pressure and high-flow nozzles used reduce the running tension of the fabric, reduce hairiness and yarn cracking, and improve the fiber expansion and dyeing effect.
02
No creases and curling
The fabric expansion device allows the fabric to expand appropriately during the buffering process and its shape changes continuously in the dye solution, so that the fabric is not easy to produce creases and curling, achieving the effect of stretching and curling.
03
Simple operation method
The highly intelligent and high-precision computer control program can realize fully automatic DOSING dosing control, as well as efficient water inlet and drainage systems. At the same time, a preparatory cylinder can be purchased to recycle heat energy and reduce costs.
04
Precise fabric speed control
High-performance variable frequency stepless speed regulation can match the fabric speed with the process time in any speed range, avoiding the phenomenon of fabric surface defects caused by mismatch of fabric speed synchronization.
05
Advantages
Excellent Dye Penetration
The high-temperature, high-pressure process achieves deep, uniform dye absorption, resulting in vibrant colors, excellent colorfastness (to washing, light, and rubbing), and fewer dyeing defects (e.g., streaking and uneven color).
01
Highly Efficient for Synthetic Fibers
Eliminates the need for carrier chemicals (typically used to help dyes penetrate polyester fibers at lower temperatures), reducing chemical usage and wastewater pollution.
02
Versatility
A wide range of fabric weights and types can be processed, from lightweight knits to mid-weight wovens, with parameters adjustable for specific materials.
03
Process Control
Precisely regulates temperature, pressure, and liquid flow to ensure consistent dyeing results from batch to batch.
