Texture is the perceived surface quality of fabrics, physiologically detected by sight or touch. Tactile textures refer to the immediate tangible feel of a surface, whereas visual textures refer to the visual impression that textures produce to human observer, which are related to local spatial variations of simple stimuli like colour, orientation and intensity in an image. In this paper attention is focused on defining the visual texture of pantyhose, in particular macro roughness and luster, and their interdependence with yarn count and composition.
A set of samples in single jersey knit with yarn count ranging between 5dtex and 78dtex were produced. The sample included fabrics made of pure nylon, as well as blends with elastane, trilobal filaments and microfiber. A panel of 40 evaluators visually rated the luster and roughness of each sample. Each property was rated on a five point polar opposites scale. Luster of fabrics was examined by the opposites of lustrous/dull, whereas macro roughness was described as smooth/rough and even/uneven. A viewing cabinet with a white light source set under a 15o angle with black background was used to standardize the evaluation. A knee-height leg model composed of vinyl chloride was used as the sample subject, with color values of L* = 59.5, a* = 22.4 and b* = 23.9. A realistic leg model was chosen in order to provide a visual simulation closest to actual wearing conditions. Considerable differences in both the perception of luster and roughness were found. The perception of luster depended on the fibre content of the knits. For instance, the addition of microfiber renders the pantyhose with a matte surface, while the addition of trilobal filaments increases luster. Coarser yarns contribute to a smoother and more even surface texture. A Pearson’s correlation coefficient of -0.88 and -0.99 signifies a high correlation between yarn count and smoothness and evenness, accordingly.
