UHMWPE woven fabric combines ultra-high molecular weight polyethylene fiber and special ultra-high molecular materials, using special high-density textile machinery processing, and manufacturing of knife-cut fabric. UHMWPE woven fabric has anti-knife, glass, and other sharp objects at the same time with an anti-bite function. In order to be able to produce a compliant UHMWPE woven fabric, rigorous performance testing is required at the time of production.

Because of the high specific strength, high specific modulus and more than ten times of the steel wire with the same cross-section, the specific modulus of UHMWPE woven fabric is second only to the special grade carbon fiber. The gripper of the fiber strength tester is required not only to clamp the fiber sample without slipping in the tensile test but also not to damage the fiber due to excessive clamping force. The early electronic strength tester used a manual gripper to clamp the fiber sample with a manual screw, the gripping force was difficult to control, in order to prevent the sample from slipping, the gripping force was often too large for manual operation, and the stress concentration at the gripper jaws is too much, and the strength and elongation of the test results are on the low side, which brings adverse results to the correct evaluation of the fiber quality. The pneumatic gripper can be operated automatically, the gripping force is constant and can be controlled by adjusting the air pressure, which reduces the influence of the operator on the test results. Only the high strength and high modulus fiber strength tester with a pneumatic gripper can meet the testing requirements of the tensile properties of UHMWPE woven fabric.

With the development of the economic era, people pay attention to security, the anti-cut fabric has become the main point, and UHMWPE woven fabric will be more and more popular.
