Filament sticking caused by uneven oil agent on PET fiber surface
Problem Phenomenon
Multiple PET filaments stick together during winding, making subsequent drawing difficult.
Cause Analysis
Spinning oil agent application is uneven or the oiling nozzle is clogged; oil agent amounts differ greatly between fibers; oil agent emulsion concentration fluctuates.
Solution
Check and clean the oiling nozzle; stabilize oil agent emulsion concentration and temperature; use a metering pump to ensure uniform oiling.
Key Takeaway
PET fiber oil agent uniformity is the foundation for ensuring fiber dispersibility.
