STRUCTURE OPTIMIZATION IN A SERIES OF DYES FOR WOOL AND COTTON - A CHEMOMETRIC APPROACH

Fastness properties on wool and cotton of a series of acid dyes, previously designed by a chemometric approach and tested on silk, have been studied. Wash fastness and light fastness data of the training set have been modelled as a function of the structure by the partial least squares (PLS) method. The models established have been used successfully to predict the fastness of new dyes of the series. Comparisons within the fastness performance of the series on the three fibres have allowed the identification of the best dyes for each of the fibres.
