The Friction Tester is designed to evaluate the tactile performance of fabrics and other materials by simulating the “stroking” motions used by craftsmen and professionals. It quantifies frictional characteristics through measurements of friction coefficient (MIU), friction coefficient deviation (MMD), and surface roughness (SMD), providing objective data on smoothness, slip, and roughness. This instrument is also suitable for delicate materials, including hair, offering precise tactile assessment.
You can use the STD-SE Friction Tester across multiple industries:
Textiles: Assess fabrics, gauze, and nonwoven materials for friction and surface roughness.
Hygiene products: Test tactile performance of materials such as diapers.
Cosmetic packaging: Analyze surface smoothness and feel of packaging materials.
Hair testing: Measure smoothness, softness, and roughness of hair.
Furniture and automotive interiors: Evaluate tactile properties of leather, synthetic leather, and seat materials.Standards
