Exploring the Psychophysical Relationship Between Basic Fabric Construction Parameters and Typical Tactile Sensations
The psychophysical relationship between fabric construction parameters and tactile sensations remains unknown, and it limits the development of textile products as well as their virtual rendering techniques. To uncover the underlying psychophysical relationship, this study designed a series of plain woven fabrics, and two basic construction parameters, i.e., weft yarn density and weft yarn diameter, gradually change. Meanwhile, the typical tactile sensations of these fabrics are evaluated by the magnitude estimation method and the paired comparison method. By applying the classical psychometric analysis to the sensation evaluation data, the discrimination threshold and the Weber fraction are calculated, respectively. From psychometric analysis, both perceived roughness and softness sensation decreased with an increase of weft density and weft yarn diameter. The Weber fraction for weft density is 0.16 in roughness and 0.21 in softness, for yarn diameter 0.3 in roughness and 0.26 in softness, respectively.
