Thermal Shrinkage Test of Immersion Yarns

The heat shrinkage test of dipped canvas can measure the dry heat shrinkage rate and dry heat shrinkage force of dipped yarns, cords and cords in hot air. Zhongke Testing and Reliability Experiment Center has the capabilities of environmental testing and reliability performance testing of various dipped yarns, and provides professional heat shrinkage testing services for dipped yarns, cords and cords.

Dip yarn, cord and cord made of nylon and polyester fibers.

uses a dry heat shrinkage meter or a thermal cycle oven to measure and calculate the dry heat shrinkage rate, dry heat shrinkage force, and free dry heat shrinkage rate of dipped yarns, cords and cords under pre-tensioned conditions in hot air at a constant temperature after a specified time.
