Abstract: One of the parameters that affects the colour appearance of a given material is the moisture content. The wet to dry colour change slows down the process of colour matching because, in present practice, a sample from a dyebath must be dried before it can be assessed. The process would be much more efficient if the colour of the sample when dry could be accurately predicted from the colour of wet sample taken fresh from the dyebath. The dry colour of fabric is affected by parameters such as refractive index of medium and moisture. Studies have been carried out to examine the effect of moisture content on the colour appearance of the dyed textile materials and proposed a geometric model to predict the dry reflectance value from wet materials. The use of refractive index of the embedding medium and the modified Kubelka-Munk equation to predict the dry reflectance value from wet materials have also been studied. In this paper, various parameters that affect the dry colour of fabric, their measurement and various approaches used for the assessment of dry state colour of the fabric from its wet state colour have been reviewed.
