Calculating and Measuring Fabric Colour for Fabrics Made of Yarns of Different Colour

Abstract

Colour measurement has recently advanced considerably, but has unfortunately not been much used in weaving practice. Contemporary techniques of computer-aided fabric designing offer new possibilities, both in developing new designing procedures and in quite practical areas of application. It is thus necessary to define a functional link between colour measurement parameters and fabric construction ones. The theory presented here offers the basis of colour measurement, as well as the technique of calculating the content of a particular colour in a fabric sample repeat. Experimental part describes the comparison of errors in calculated value of fabric colour, obtained on computer- simulated fabric constructions for fabrics made of yarns with predetermined properties, and the errors obtained by spectrophotometric measurements of the values on the above simulations.
