Colouration Technology

Research area.

Dye application processes are commonly well-established as a result of many years of practical experience in dyeing. In contrast, a fundamental understanding of the mechanisms through which dyes are absorbed by fibres is still not completely achieved for many dye-fibre systems. With the introduction of ever-finer fibres and novel polymer fibres for the production of textile fabrics, the general need for a basic understanding of the relation between fibre and dyeing properties has become vital.

To understand the driving forces of the dyeing process, a generic fundamental analysis is followed within the Department of Textiles. This involves, amongst others, the study of dye diffusion processes, the importance of thermal properties of the dye-fibre system, the relevance of variations in fibre morphology, the study of dye-fibre interactions. To perform this study, various novel measurements methods were set up specifically for the use on textile materials.

While colouring textiles has been a basic functionalisation mainly driven by aesthetics reasons for many years, recently new application areas involving colour have gained a lot of interest. The application of a colour changing functionality to textiles is an example of such an innovative use of dyes.
