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