The leather seam fatigue testing machine is used to test interior materials by subjecting samples to periodic tensile and recovery cycles under specified test conditions. After a specified number of cycles, the maximum needle hole elongation at the seam is measured to evaluate the fatigue resistance of the seam.
Application
The leather seam fatigue testing machine is used to evaluate the fatigue strength of seams in automotive seat surface materials. Automotive seat surface materials (genuine leather, synthetic leather, fabric, etc.) often have a stitched seam structure, and the stitching strength and fatigue resistance of these seams directly affect the lifespan of the seat. By testing the strength and lifespan of the material seams, it is possible to effectively predict the seat's lifespan and identify areas for improvement to extend its service life.
Standard Test
ISO 5402: Leather physical testing – Flex tester method for adhesion and strength analysis.
SATRA TM55: Seam fatigue testing for footwear, ensuring stitching integrity under cyclic stress.
