Draft point drift of PET fiber
Problembeschreibung
During PET fiber drawing, the draft point position is unstable and moves back and forth, causing fiber fineness fluctuation.
Ursachenanalyse
Drawing temperature is unstable; drawing roller speed fluctuates; fiber preheating is uneven; undrawn yarn quality fluctuates.
Lösung
Stabilize drawing temperature and speed; ensure uniform fiber preheating (hot plate/hot roller ±1°C); control undrawn yarn quality consistency.
Wichtigste Erkenntnis
PET fiber draft point stability determines fiber fineness uniformity.
