The Thermal Shrinkage Tester TST 1 tests the impact of hot air on wider samples and tapes made of synthetic film, nonwoven materials, laminated products and fabrics. Product details and test parameters are entered in the software program. The sample is prepared and pre-tensioned by means of clamping pretension weights onto the sample end. 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 sample, which are heated by hot air to the pre-set temperature. After completed heating period, the oven automatically uncovers the sample to finish the measurement or to start an optional measurement of the residual shrinkage properties of the tested material, all depending on entered test specifications.
