Yarn hot air thermal shrinkage tester is used for the shrink test of yarn and cord at controlled temperature.
Yarn hot air thermal shrinkage tester has below technical features:
- PLC control and touch screen operation
- Yarn holder and heat unit separate design, not interfere between yarn sample and heating area before test
- PID temperature control
- Precious shrink displacement measurement
- Temperature range: ambient~250°C, accuracy 0.1°C
- Time range up to 9999 seconds(or as required)
- Professional software is optional
Yarn hot air thermal shrinkage tester standards to follow:
ASTM D 4974: Standard Test Method for Hot Air Thermal Shrinkage of Yarn and Cord Using a Thermal Shrinkage Oven
