Quantitative investigation of the surface color's effect on the hand evaluation of pile fabrics.

This is a paper concerned with investigating how the consumers and specialists perceive value or chroma differences of color pile fabrics in various value or chroma conditions. And the relationships between sensory values evaluated by the sense of sight and the visual physical properties (hue, value and chroma) were examined by the use of multiple regression analysis.The results are as follows.(1) When consumers converted the visual physical properties (hue, value and chroma) into the sensory values, their change rate were high. But the change accuracies were not good. On the other hand, the specialists' change rates from the visual physical properties to the sensory values were low because of a long term training in the color recognition.(2) As a result of multiple regression analysis, it was found that the common predictive variable of the four sensory values “softness”, “thickness”, “smoothness” and “lightness” evaluated by consumers and specialists was mainly value and that “fullness” was described by the multiple regression equation of hue and chroma.
