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:

1. PLC control and touch screen operation
2. Yarn holder and heat unit separate design, not interfere between yarn sample and heating area before test
3. PID temperature control
4. Precious shrink displacement measurement
5. Temperature range: ambient~250°C, accuracy 0.1°C
6. Time range up to 9999 seconds(or as required)
7. 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
