Abstract:
1. A device for determining softness of an at least single-ply sanitary paper or textile, wherein the device comprises a scraper element disposed vertically on an axis, wherein the scraper element is: (i) arranged for rotation relative to a stationarily positioned, at least single-ply, horizontally oriented sample of the sanitary paper or textile and configured for displacement along the axis relative to the sample, which is secured on a measurement housing, when subjected to a defined penetration force applied orthogonally on the sample, or (ii) stationary relative to a rotatable, at least single-ply, horizontally oriented sample of the sanitary paper or textile, with the sample, which is secured on a measurement housing, being configured for displacement along the axis when subjected to a defined penetration force by the scraper element applied orthogonally on the sample such that the scraper element penetrates into the sample while deforming the sample, wherein a vibration sensor is disposed in the region where vibrations are generated between the sample and the scraper element, with the vibration sensor configured to record sound generated from the vibrations when the scraper element, operating on the sample, rotates about the axis or when the sample, operating on the scraper element, rotates about the axis.
