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, previ ously designed by a chemometric approach and tested on silk, have been studied. Wash fastness and light fastness data of the training set ha ve been modelled as a function of the structure by the partial least s quares (PLS) method. The models established have been used successfull y to predict the fastness of new dyes of the series. Comparisons withi n the fastness performance of the series on the three fibres have allo wed the identification of the best dyes for each of the fibres.
