Colorimetric Analysis and Visual Valuation of Colours on Two-Coloured Fabrics

Abstract

In this article, spectrophotometric and visual analysis of colours on the surface of two- coloured fabrics is presented. Analysis of measured colours showed that a colour of a two-coloured fabric depends on characteristics of chosen colour components, as well as on the weave, which defines the quantity proportions of colour surfaces on the fabric‘s face, their shape and their size. Visual analysis confirms that the perceived colour of a fabric is uniform in cases when colour surfaces are very small. At larger colour surfaces, various colour phenomena strongly influence the perceived colour of a fabric. Besides, the fabric‘s colour is influenced by shapes and sizes of colour surfaces, such as bigger dots at the hopsack weave and lines at the twill, which guide the observer‘s sight and have noticeable influence on visual impression of a fabric. The results should be of great assistance for textile designers, who usually plan fabrics‘ colours by the application of their experiences and by analysing woven or virtually simulated fabrics.
