TSA - Tactile Sensation Analyzer

The emtec TSA measures softness, roughness and stiffness of textiles and nonwovens objectively and reliably. Together with the stiffness, the elasticity, plasticity and hysteresis, which determine the elongation as well as the recovery behavior of the material, are measured. By the help of mathematical models, so-called hand feel values can be calculated, which correlate very well with the human expectation.


Benefits

objective determination of the softness, roughness and stiffness (independent availability of the results)
measurement of elasticity (elongation) as well as of hysteresis and plasticity (recovery behavior) are integrated in standard measurement
measurement of the compressibility and crumplability with special modules possible
calculation of a so-called HF (hand feel) value by different algorithms possible (HF value = touch, comfort)
special finished goods, such as diapers, femcare products or seat belts can be measured by the help of special adapters
excellent correlation with the human tactile sensation
accurate and reliable
easy handling and transportation

Product description

The touch or comfort of a nonwoven or textile product becomes a more and more important quality parameter. Different expectations of different people, especially when they are coming from completely different parts in the world make it hard to create the right mix of soft and smooth and flexible or stiff. Additionally each type of nonwoven or textile product needs its own mix, a t-shirt needs to feel different compared to a pair of jeans, a wet wipe needs to feel different compared to a baby diaper. Humans can rank or rate different qualities of a nonwoven or textile product according to the overall haptic impression. But for a human it is hard to say, why one product is preferred over the other, is it because of a softer or smoother feel or is one a bit more flexible than the other one? Those questions cannot be answered by hand tests.

The emtec TSA Tactile Sensation Analyzer in comparison to this measures the three basic haptic parameters micro-surface variations (determine the feeling of softness), macro-surface variations (determine the feeling of smoothness) and the stiffness. Besides the three, plasticity and hysteresis, which determine the recovery, and the elasticity (elongation) are measured objectively and individually by the device. From all these parameters, a hand feel value (touch, comfort) can be calculated by algorithms. The algorithms need to be adapted to the market where the tested product is supposed to be sold and to its application. Hand feel values, calculated by adapted algorithms, often show a correlation of up to almost 100 percent to the human perception.
