High breakage rate in PET fiber spinning
Sorun Belirtisi
Frequent breakage during PET melt spinning, poor production continuity, uneven fiber quality.
Neden Analizi
Gel particles or impurities in the melt, improper spinning temperature, filter screen clogging, unstable cooling conditions.
Çözüm
Improve filtration accuracy (20-40μm filter screens), optimize spinning temperature 280-295°C, control melt residence time <15min, stabilize side-blowing air.
Temel Çıkarım
PET spinning breakage is a comprehensive reflection of raw material purity, temperature, and filtration.
