Table 4: Pearson correlation factors between human and instrumental hand-feel related parameters. As for woven fabrics, the hand-feel panel showed an acceptable correlation with the \"softness\" results from the reference panel, while no agreement was found regarding \"smoothness\" was found. No substantial correlation between human perception and measured physical parameters was observed. The assessment of the hand-feel properties of lightweight woven fabrics shows a wider variation in the results than obtained with the knitted ones. Low or no correlation of the panel with all relevant Kawabata parameters was observed. Also, with TSA the correlation was poor. The highest correlation factor (0.63) was observed between the acoustic TS750 and the property \"drapey/stiff\". Being based on acoustic measurement, the airflow through the fabric plays a role in the received signal strength. In the standard measurement protocol used in this study, the microphone is positioned below the fabric, while the rotating part is above.
