Universal Yarn Tester for Filament Yarns DYNAFIL ME+
The DYNAFIL ME+ is a dynamic yarn tester measuring yarn properties such as draw-force, shrinkage or crimp on the running thread. Since draw-force and shrinkage correlate with the molecular orientation, these parameters are especially indicative for dye-uptake in Polyester. The tester is equipped with two separate godet rollers – optionally with nip rollers – with individual high-precision electronic drives for yarn speeds up to 1000 m/min. A non-contact heater (500 °C) with flap and driving mechanism for automatic threading into the heater channel facilitates threading and allows heater temperature above the melting point of the yarn.
The tester can measure
- Draw-force of POY, FDY or FOY
- Crimp-force or percent crimp of DTY
- Shrinkage-force or percent shrinkage of all kinds of yarns
