Yarn Hot Air Thermal Shrinkage Tester Comply ASTM D4974

Introduction:

This instrument uses a high-precision temperature control system and measurement system to accurately test the dry heat shrinkage performance (shrinkage rate and shrinkage force) of tire cords, yarns, polyester, cotton threads and textiles under certain temperature control.

Instrument Features:

One machine with two purposes: shrinkage rate test, shrinkage force test;

The system uses a touch screen for man-machine dialogue, and directly performs input operations on the interface. Display the working status of the system in the form of animation, as well as real-time deformation curves, contraction force curves, temperature curves, heating curves, etc. The system has a real-time fault alarm function and directly displays the alarm information;

Directly use the temperature module to collect the temperature, use the built-in thermocouple, and perform PID control to output the heater. And the heating temperature and heating speed can be set on the touch screen, and the temperature and heating curve can be displayed at the same time;

Through the LCD display, the current test data can be intuitively displayed, and the data storage function can be provided at the same time, multiple sets of test results can be queried, and the test results can be calculated;

The PLC reads the encoded signal from the encoder measurement system, draws the curve directly on the touch screen, and can print and view the historical storage;

PLC reads the pressure signal from the force measuring system, draws the curve directly on the touch screen, and can print and view the history storage;

A micro-printer that prints the two values ​​of the test shrinkage rate and shrinkage force respectively, and prints the test curve.
