Many authors suggest evaluating the tactile hand properties of textiles in such a way that the sample cannot be seen, but this can be a cumbersome procedure. This study tested the effect of a strong visual attribute, color, on hand perception of fabrics in both descriptive and consumer studies. Panelists evaluated four cotton fabrics: poplin, flannel, knit and twill, each dyed five colors: white (no dye), dark blue, light blue, pink and yellow. In the descriptive study, minimal differences were found for only one color, yellow, in one fabric type, poplin, for four attributes: gritty, hand friction, fabric friction and softness. For the consumer study, only "brightness," a visual perception, and "harshness," which may be either visual or tactile, were different across fabrics from one color to another. Based on this study of color effects, there appears to be negligible impact of visual perception on tactile hand evaluation. This data would suggest there is little need to block the view of fabrics during hand evaluation in either descriptive or consumer studies.
PRACTICAL APPLICATIONSData from this study suggest that the need to go to extraordinary means, such as blindfolding panelists, to block potential visual bias in tests of fabric 3 Corresponding
