【 摘 要 】

The characteristic of the colour fastness assessment for multi-colours fabrics were investigated. Visual assessments were conducted by experts for assessing colour fastness. The obtained visual results were compared with colour fastness from an instrumental colour fastness rating as a reference value. In addition, the assessment by the experts were compared with that of non-experts obtained in a previous study. As the results, the visual ratings of experts and non-experts were around 1 rating higher than the instrumental ratings. There were some differences in the assessments between the experts and the non-experts, and also among the experts. These results indicates that it is difficult to assess the colour changes of multicoloured fabrics.
