The Latest Information of Softness Measurement by Acoustic and Stress

Abstract

In many cases, touch feeling evaluation is often performed by a panel test method in which the product staff and inspectors evaluate and quantify the feeling when they actually touch the product. However, what one person finds to be nicer and softer may not feel the same to another. Texture is subjective and tends to vary by individual, gender, and nationality. In order to increase the objectivity of the evaluation, it is desirable to use the equipment rather than the panelists.

Germany’s emtec electronic company’s TSA softness measurement device is a device that evaluates the softness and texture of paper products such as tissue products. A measurement method that simulates the vibration and stress felt by human fingertips, and measures the three parameters that affect the feel of the hand：true “softness”, “smoothness/roughness”, and “rigidity/flexibility”. In addition, the overall texture is evaluated as an HF value.
