Effects of Fabric Color on Visually Perceived Pantyhose Surface Roughness via Investigation Using Plate-Type Leg Model

In this study, the influences of the fabric color of pantyhose (PS) on the visually perceived surface roughness were investigated. Sensory evaluations and relevant statistical analyses of the visually perceived PS surface roughness (VPPSSR) were conducted using a plate-type leg model for Japanese females; the model was covered with beige-colored PS. The visual information of the PS-covered plate-type leg model did not provide visual features usable as cues for the visual evaluation of an objectʼs surface roughness, such as a highlight pattern. The PS-covered leg models used for the sensory evaluation included eight different beige fabric colors and three different apparent colors, owing to differences in the stitch density on the leg model. Additionally,the visual features obtained via an image analysis of the PS-covered leg model were examined. As a result, it was confirmed that the VPPSSR was influenced by the apparent color of the PS-covered leg model. In conclusion, the VPPSSR in beige-colored PS is influenced by the fabric color, especially the L* value; the brighter the fabric color, the finer the VPPSSR.
