The roles of elevated temperature and carriers in the dyeing of polyester fibres using disperse dyes: Part 4 plasticisation model of dye diffusion

Abstract

This review concerns the application of disperse dyes to poly(ethylene terephthalate) fibres using aqueous immersion dyeing processes and the roles of both elevated dyeing temperatures and carriers in the dyeing system. In this part of the paper, a novel plasticisation model of dye diffusion is proposed which reflects the crucially important mechanistic role that water‐induced fibre/polymer plasticisation adopts in the diffusion of disperse dyes within polyester and other types of polymeric material.
