Optimisation of the colour sequence in the process of fabric dyeing

Abstract

When programming a dyeing machine, a sequence of colours has been established in an attempt to reduce the effects caused by dye residues on the colours that are subsequently applied. In this paper a model is presented that makes it possible to determine the optimum sequence. Using a optimisation method, the sequence that minimises the sum of the photocolorimetric differences between the colours required and those obtained has been determined. In order to estimate the change that each colour undergoes due to the presence of residual dye in the dyeing equipment a computer calculation method has been adopted.
