DESIGN OF DYES OF HIGH TECHNICAL PROPERTIES FOR SILK BY A CHEMOMETRICAPPROACH

A range of amines and coupling components were explored with the aim o f identifying the best structures in a series of acid azo dyes for sil k. The technique of the Experimental Design in Principal Properties wa s used for the selection of a small number of dyes to be synthesized a nd tested. Fastness data have been modelled as a function of the struc ture by the Partial Least Squares (PLS) method. The models established allowed the prediction of the fastness of new dyes of the series. Thr ee violet dyes, one in the training set and two in the prediction set, with outstanding fastness performance were identified.
