At the Index trade fair in Geneva/Switzerland from October 19-22, 2021, emtec Electronic will present a state-of-the-art device for the objective measurement of fabric softness. 

Traditionally, manufacturers of textiles and nonwovens use handpanels comprised of individual judges to assess a material’s haptic properties. In contrast, the Tactile Sensation Analyzer from emtec Electronic GmbH, Leipzig/Germany presents an interesting approach: a sound analysis in 2 different frequency areas determines a material’s softness and roughness. Parameters such as stiffness, plasticity, hysteresis and elasticity are then measured with a deformation measurement, i.e. how much a product deforms under a certain load and how well it recovers after deformation. Specific algorithms can combine these individually measured parameters into so-called handfeel values, which correlate very well with the human tactile sensation. 

Independent evaluations from the industry designed to test the functionality and efficacy of the TSA device have consistently found the results to be highly comparable to the results of physical tests and handpanels.
