TST 510/250 Thermal Shrinkage Tester

    • TST 510/250 Thermal Shrinkage Tester

    At a preset temperature, the change in the shrinkage length and the heat shrinkage force of filaments and yarns are two important parameters in industry and technology.
     The specially designed box heater can avoid the influence of the surrounding environment. Together with the high-resolution length detection sensor and force sensor, after the sample is placed, the test will be completed automatically under computer control to avoid human error.
     During the testing process, the thermal shrinkage changes of the yarn will be displayed in the graph connected to the computer, and the testing results can be fully analyzed and evaluated.

    • Excellent performance

      • In a heating cabinet after TST 510/250 heated to a predetermined temperature, a detectable change in contractile force and shrinkage of the yarn within a predetermined time, after detecting further detectable residual shrinkage force and residual shrinkage yarn. Automatically monitor the change of sample length and contraction force through a connected computer.
      • The heating box is automatically moved by computer control to ensure the accuracy of the test. The entire test process is fully automated, which not only saves manpower, but also avoids human error, and can also ensure the repeatability and accuracy of the test results.
      • The operator can customize the TST 510/250 inspection program according to the requirements. For example, the residence time of heating, different pretension and so on. TST 510/250 can help you get the length difference change.
      • TST 510/250 also has a dynamic test function, which allows you to observe the changes in the sample during the heating process.
      • During the test, all performance trends of the heated yarn are automatically recorded. This allows you to check product irregularities in detail, while also providing a reliable tool for research and development.
