Structure optimization in a series of acid dyes for wool and nylon

A series of acid azo dyes, previously designed by a chemometric approach for silk, has been applied to wool and to nylon, in order to compare the fastness performance of the series on different fibres of analogous structure. Wash fastness and light fastness data have been modelled as a function of t...

Description
Summary:A series of acid azo dyes, previously designed by a chemometric approach for silk, has been applied to wool and to nylon, in order to compare the fastness performance of the series on different fibres of analogous structure. Wash fastness and light fastness data have been modelled as a function of the structure, described by the principal properties of the substituents and p K values of the dyes, experimentally determined. PLS models allowed the identification of the best dyes for each of the fibres.
