Our independently designed and developed test system of stress and strain characteristics of special textile materials in hygrothermal environment is used to simulate the physical characteristics and the change process of the sample under the natural environment such as temperature and humidity change, so as to provide reliable date support for the special textile material manufacturers, promote the development of the product and improve the quality of the products.

1. The transmission mechanism adopts imported ball screw group, synchronous belt, synchronous wheel and AC servo system. Stable and accurate operation with little noise.
2. The surface of the instrument is sprayed with high temperature and cured for long time without fading.
3. Imported high-precision force sensor, high speed precision 24 bits A/D, instrument sampling frequency is 1000HZ.
4. Using 32 bit Cortex-M3 microprocessor, the operation is strong, the data processing speed is fast, the instrument response is sensitive, and the operation is stable and reliable.
5. Full computer professional software manipulation, software system: simple operation, easy to understand, powerful.
6. Equipment test time is long, the environment needs subzero test.
7. The force value of the test is large, the fixture requires professional design, and the fixture can be customized according to the requirements of the customer sample.
8. The temperature difference is big, the request progress is high, the gas circulation structure.
9. Static loading creep function was used to test the creep resistance of the tested material.
10. The instrument integrates material testing machine and high and low temperature wet heat test box function, and simulate the physical characteristics and change process of the special spinning material under the high humidity environment. It can run independently, such as high and low humidity test of material, testing function of material testing machine.
