For high-temperature dyeing machines, how does liquor ratio affect shade variation and dye cost, and what drives price differences among liquor-ratio models?
• Low liquor ratio 1:4-1:6 saves 15%-25% dye and 20% steam, but needs stronger circulation pump to avoid uneven dyeing.
• Below 1:4, fabric speed must be ≥350 m/min to prevent crease marks and shade variation.
• Price gaps come mainly from main pump power, heat-exchanger area and level-control accuracy.
• Require ΔE ≤0.8 across three consecutive batches in same dye lot; otherwise liquor control is unstable.
• Low-ratio models need inverter pump and flow meter; water use can drop below 80 L/kg fabric.
