The new developed dyeing machine adopts O-shaped body, installed with special S shape stackable inner-trough. The fabric is transported smoothly in extended condition along the square inner-trough. The capacity of the machine is 1.5 times larger than the ordinary O type machine。
The machine adopted the S shape stackable inner-trough and well-moderated net  aperture, which is able to enhance the flow dynamic of the fabric. This enables the machine to operate with low liquor ratio from 1:3~1:4 under different types of fabric and operation procedure。
When using rectangular cross-section stackable S shape inner-trough for the fiber dyeing process, the fabric has low hydro content and is under low-tension condition, when going trough the nozzle head. This ensures no vertical crease marks are created on the fabric。
To achieve evenly and speedy dying result, extended square shaped and full-liquor dying tube is used.
The fabric is able to transport in the machine with speed up to 700m/min. The fabric circulated back to the inner- trough in a natural spread out and nicely folded status. The machine suits large variety of fabric, and it does not create unnmecessary fold and roll-up border. Its capacity is extensive and is suitable to dye tricot.
