Excessive fuzz after PET fiber drawing
Fenómeno del problema
After PET spinning and drawing, a large amount of fuzz and broken filaments appear on the fiber surface, affecting weaving.
Análisis de la causa
Drawing temperature is on the low side; excessive stress produces micro-cracks; drawing roller surfaces are rough or damaged; oil agent is insufficient or uneven.
Solución
Appropriately increase drawing temperature (Tg+10~30°C); check and polish drawing rollers; ensure uniform oil agent application.
Conclusión clave
PET fiber fuzz originates from fiber surface damage during the drawing process.
