Analysis of the Stability of POY Filament Structure and Properties Spun by WINGS System

摘要

Comparing the crystal orientation of the structure,tensile properties,boiling water shrinkage rate between difference filament rolls in the same spinning position spun by WINGS POY system and tradition ACW POY system,it is found that there are differences in orientation degree,crystallinity,tensile strength,elongation at break,initial modulus and boiling water shrinkage rate between difference filament rolls in the same spinning position.Coefficient of variation of the experimental values of WINGS POY system is lower than traditional ACW POY system.
