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)
