Tensile and Shear Tester KES - FB1 - A
The Fabric Tensile and Shear Tester mechanically evaluates the tensile and shear behavior of materials to provide objective data for fabric hand-feel and texture analysis. It measures properties such as tensile stiffness, shear stiffness, tensile energy, elongation, and resilience, helping researchers assess fabric elasticity, stiffness, shape stability, and wrinkle tendency.
The tester uses load-controlled tensile measurement and deformation-controlled shear measurement. Its motorized clamping mechanism removes sample slack before testing to reduce setup-related measurement errors. With a display resolution of 0.01, it can distinguish small differences in the tensile and shear characteristics of materials.
Application
(1) Textile fibers and fabrics.
(2) Medical textiles and nonwoven materials.
(3) Automotive seat cushion materials and interior fabrics.
