When buying an overflow dyeing machine, how do liquor ratio and fabric tension control affect color shading and crease marks across different GSM?
• Use 1:6-1:8 liquor ratio for light fabrics; 1:4-1:5 for heavy fabrics to reduce creases.
• Maintain tension 0.5-2.0cN/dtex; too high causes warp shading, too low causes weft creases.
• Adjust nozzle pressure by GSM: 0.8-1.2bar at ≤150g/m²; 1.5-2.5bar at ≥300g/m².
• On acceptance, verify ΔE≤0.8 at left/center/right and crease rating ≥4.
• Maintain tension 0.5-2.0cN/dtex; too high causes warp shading, too low causes weft creases.
• Adjust nozzle pressure by GSM: 0.8-1.2bar at ≤150g/m²; 1.5-2.5bar at ≥300g/m².
