TEST METHOD
The Thermal Shrinkage Tester tests the impact of hot air on industrial and technical filament yarn such as tire cord. Product details and test parameters are entered in the software program.
Samples are prepared and pre-tensioned by means of clamping pretension weights onto the yarn ends. By a mouse click or by pressing the instrument button, the measurement is started
and performed according to the selected test parameters.
The oven-type heater automatically moves to cover the samples, which are heated by hot air to the pre-set temperature. After completed heating period, the oven automatically uncovers the
samples to finish the measurement or to start a measurement of the residual shrinkage properties of the filament depending on entered specifications.
BENEFITS
- Highly efficient testing
Testing of up to ten yarn samples in one and the same test run. Combine testing of shrinkage % and shrinkage force (number of samples individually selectable)
or test either up to ten samples for % shrinkage or up to ten samples for shrinkage force.
- Testing for multiple purposes
Use TST 510/250 for standardized quality control or for advanced material research and development. The extensive software program allows for individual
settings of temperature and time as well as for individually programmable test cycles to meet your testing objectives.
- Objective measurement
A fully automated measurement procedure guarantees for unbiased thermal shrinkage measurements with no human impact on the test results.
- Easy analysis at a glance
During the measurement, the impact of the heat on the tested material can be observed both graphically and numerically in real-time. After completed measurement, the generated report offers all data for detailed analysis.
