When buying a sectional warping machine, how do warp yarn tension control and creel capacity match high-count and low-count yarn warping quality?

• Use 0.15-0.25cN/dtex tension for high-count (≥60S); 0.3-0.5cN/dtex for low-count (≤20S).
• Select creel capacity 480/640/800 bobbins by total ends, with yarn break auto-stop.
• Set warping speed ≤600m/min for high-count; ≤400m/min for low-count.
• On acceptance, verify warp sheet tension CV≤5% and uniform beam hardness without loose edges.
