Statistic Modelling and Optimization of the Dyeing Process of Melana Fibres with Victoria Blue B Dye in the Presence of Anionic Retarders

摘要

The present study pursued the influence ofpolyelectrolytes based on maleic co-polymers with styrene (NaM-S) and vinylacetate (NaM-VA) under the form of natrium salt, in the tinctorial system consisting of Melana dyed with Victoria Blue B (WB)-triarylmethane dye using the colour difference (AE), as a method to evaluate the interactions. Mathematical models of the studied dyeing processes have been developed and the necessary information on their significant factors is produced by means of experiment planning methods, known as Design of Experiment (DoE) or Experimental design. Optimal correlations between the application conditions and the colour differences obtained on Melana-type fibre have also been studied.
