Difficult temperature control of PLA fiber one-step spinning and drawing
Problem Phenomenon
One-step spinning and drawing PLA has a narrow temperature window and is difficult to control.
Cause Analysis
The spinning and drawing temperature zones overlap narrowly; a slight temperature deviation produces filament breakage.
Solution
Precision temperature control system with multi-point monitoring and immediate adjustment.
Key Takeaway
PLA spinning temperature control window is narrow.
