ABSTRACT:
A method for determining key yarn properties such as modification ratio and MBB dye uptake rate by measuring yarn bundle filament velocities near the spinneret as they are melt spun. The average filament velocities only are used to determine yarn properties from a calibration curve of yarn properties versus average filament velocity.
