Plotted are 8 step measurements with polyamide. The measurements are carried out at 270°C with a die L/D = 30 / 2 mm in the deflection head and a spinning length of 1300 mm. The individual speeds are each held for 20s. For evaluation, the measured forces are averaged over the last 15s of each stage. This material always tore off shortly before or when reaching 3000 m/min.
