Leipzig-based manufacturer emtec Electronic GmbH will introduce a novel and time-saving way to evaluate the human tactile sensation in a presentation at the Performance Days Functional Fabric Fair. The event takes place on March 15-16 in Munich, Germany.
Human tactile sensation is a complex phenomenon that is influenced by many subjective factors, including hand sensitivity, personal preference, mood, and culture. For the textile industry, this subjectivity often makes it difficult to reliably reproduce the haptic qualities of a fabric, especially when sourcing and production take place in different locations. Traditionally, hand panel testing is used to evaluate and rank the fabrics based on the overall haptic impression, also known as handle or hand-feel, of the material. The drawbacks of this approach are the time needed to organize such panels, the extensive testing needed, and the subjective results, which are not always reproducible across various locations.
At 4:00 p.m. on Day One of the Performance Days fair, Sales Area Manager Eric Haagen from the testing device manufacturer emtec Electronic will present a practical solution for achieving objective, reliable, and easily reproducible haptic results: the TSA Tactile Sensation Analyzer. Using hypersensitive sound analysis, the TSA device simulates the function of the human hand by registering the sound waves produced upon contact with a sample fabric. This allows the TSA to measure the individual parameters responsible for haptic perception – namely, the softness, smoothness, stiffness, as well as deformation and recovery characteristics. Proprietary algorithms, designed to correlate with specific market preferences, enable the device to combine the parameters into an overall hand-feel value. In some cases, the results are able to achieve a nearly 100 percent correlation to the results of extensive hand panel tests, but in a fraction of the time.
Onsite, emtec representatives Eric Haagen and Stefan Rübesam will demonstrate the capabilities of the TSA.
