KES - FB2 - A Bending Tester

Function of the Tester This tester analyzes and mechanizes the "bending" hand movements of craftsmen and professionals when evaluating the style and hand - feel of fabrics. It converts the results into objective numerical data and can obtain data on bending stiffness and recoverability of all fibers, fabrics, papers/non - woven fabrics, films, etc. The bending characteristic data affects the "elasticity", "fluffiness" and "tension" of the style and hand - feel. Features - Improve data accuracy: The use of a motorized fixture makes it easy to install thin - sheet samples, avoiding measurement errors. - Display resolution: In the software, it is 0.0001. It can measure extremely small items up to a maximum of 50gf·cm, with a wide measurement range. Examples of Measured Samples All fibers, fabrics, medical fabrics, automotive seat cushions, interior fabrics, non - woven fabrics, film - like samples Specifications - Dimensions/Weight: The main body of the device, W830×D530×H370(mm)/60kg - Power Supply: AC100V, maximum power consumption 50W - Measurement action: Maximum curvature control mode (reverse control when over - torque occurs) - Measurement environment temperature and humidity: 20～30°C/50～70%RH, no condensation (standard temperature and humidity conditions: 20°C/65%RH). Install in a place less affected by wind and vibration. - Load detector: Using the torsional moment method of wire. The sensitivity (full - scale) can be switched among four ranges: 4gf·cm, 10gf·cm, 20gf·cm, 50gf·cm. The accuracy is within ±0.5% of the full - scale. - Curvature detector: Potentiometer. The maximum curvature K = ±2.5cm⁻¹. The accuracy is within ±0.5% of the full - scale. - Bending deformation speed: 0.5cm⁻¹/sec - Sample fixing method: Use a ratchet wrench to fasten with a certain torque. - Sample deformation length: 1cm - Sample size: 20cm×20cm (standard) - Sample width: 20cm (maximum) - Sample thickness: 1mm (maximum)
