Fiber Thermal Shrinkage Tester

The Fiber Thermal Shrinkage Tester is a digital instrument designed for evaluating the dry thermal shrinkage of staple chemical fibers. By using imaging technology, the instrument automatically measures changes in fiber length before and after heating, calculates average shrinkage and coefficient of variation, and displays and prints results digitally. It is widely used in chemical fiber production, textile enterprises, inspection agencies, and research institutions to ensure fiber quality and compliance with thermal shrinkage standards.

Application

This tester is ideal for thermal shrinkage testing of single chemical fibers in production and quality control processes. Its high-precision measurement and automated data output streamline testing in chemical fiber manufacturing, textile production, fiber inspection labs, and research institutes. The compact design and imaging technology make it efficient for routine testing while ensuring accuracy and stability.
