High breakage rate in PET fiber spinning
Fenómeno del problema
Frequent breakage during PET melt spinning, poor production continuity, uneven fiber quality.
Análisis de la causa
Gel particles or impurities in the melt, improper spinning temperature, filter screen clogging, unstable cooling conditions.
Solución
Improve filtration accuracy (20-40μm filter screens), optimize spinning temperature 280-295°C, control melt residence time <15min, stabilize side-blowing air.
Conclusión clave
PET spinning breakage is a comprehensive reflection of raw material purity, temperature, and filtration.
