Draft point drift of PET fiber
Fenómeno del problema
During PET fiber drawing, the draft point position is unstable and moves back and forth, causing fiber fineness fluctuation.
Análisis de la causa
Drawing temperature is unstable; drawing roller speed fluctuates; fiber preheating is uneven; undrawn yarn quality fluctuates.
Solución
Stabilize drawing temperature and speed; ensure uniform fiber preheating (hot plate/hot roller ±1°C); control undrawn yarn quality consistency.
Conclusión clave
PET fiber draft point stability determines fiber fineness uniformity.
