Draft point drift of PET fiber
Problem Phenomenon
During PET fiber drawing, the draft point position is unstable and moves back and forth, causing fiber fineness fluctuation.
Cause Analysis
Drawing temperature is unstable; drawing roller speed fluctuates; fiber preheating is uneven; undrawn yarn quality fluctuates.
Solution
Stabilize drawing temperature and speed; ensure uniform fiber preheating (hot plate/hot roller ±1°C); control undrawn yarn quality consistency.
Key Takeaway
PET fiber draft point stability determines fiber fineness uniformity.
