Seam Fatigue Tester YG(B)021C

[Instrument Name]：Fabric Seam Fatigue Tester

[Scope of Application]: It is used to test the seam strength of materials used on automotive seat surfaces.

[Test Mode]: This machine tests the fatigue resistance of seams. Under specified test conditions, the stitched specimen is placed in the machine, and a repeated tension-release cycle is applied at a fixed frequency. After a set number of cycles, the specimen remains in the machine in a static state under the original load, and the dimensions of the stitch holes are measured to determine the seam fatigue resistance.
