Improved measurement results
"Research and testing for nonwovens" was one of the focus topics of the second day of the symposium. Within this scope, Alexander Grüner, Global Marketing and Business Development Manager at German testing equipment supplier emtec Electronic, explained a new method for process optimisation, quality assurance and R&D. Indeed, the objective technical device he presented could be a means to solve the problem of hand-feel tests: due to the different sensitivity of hand nerves, a lot of variations are observed, leading to biased results. According to Grüner, the TSA (Tissue Softness Analyser) which was originally developed for the tissue industry gives reliable and objective information about the real softness, smoothness/roughness, stiffness as well as the final hand feeling. The measurement is done in two steps - a sound analysis and a bode moving over the sample creating a vibration according to the surface topography - and the availability of these parameters opened a huge amount of chances for the optimisation of the production and converting processes, he said.
