摘要

本文综述了分散染料在聚对苯二甲酸乙酯纤维中的应用，以及提高染色温度和载体在分散染料/聚酯纤维和分散染料/载体/聚酯纤维染色体系中的作用。本文基于染料溶解度对分散染料- pet纤维物质性的影响，建立了分散染料吸附过程的机理模型。研究表明，分散染料吸附的染料溶解度模型可以用简单的数学方法来阐述，它能够解释为什么在HT染色过程中使用升高的染色温度，以及为什么染色促进剂能够在~100℃的较低温度下实现染色。

The roles of elevated temperature and carriers in the dyeing of polyester fibres using disperse dyes: Part 3 model of dye adsorption based on dye solubility

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 disperse dye/polyester fibre and disperse dye/carrier/polyester fibre dyeing systems, respectively. In this part of the paper, a mechanistic model of the disperse dye adsorption process is presented that is based on the role of dye solubility in disperse dye-PET fibre substantivity. It is shown that the dye solubility model of disperse dye adsorption, which can be articulated using a simple mathematical approach, is able to account for the reasons why elevated dyeing temperatures are utilised in HT dyeing processes, and also why dyeing accelerants enable dyeing to be achieved using lower temperatures of ~100°C.
