Double Pendulum Digital Tear Tester
The double pendulum digital tear tester is mainly used to measure the ability of various fabrics (such as clothing fabrics, home textile fabrics, etc.) to resist tearing.
Applications
Textile industry:
It is widely used in fabric production and clothing manufacturing to help manufacturers and quality inspection agencies detect fabric quality and ensure that the products meet relevant standards and usage requirements.
Research field:
Researchers use this instrument to study the effects of different fibers, fabric structures and other factors on tearing performance in order to develop new high-performance fabrics.
