Dyeing of Synthetic Fibres – course description 

To extend and deepen understanding of the fundamentals of synthetic fibres and the interaction between these fibres and the specific dyes employed at the molecular level.

The first part of the course covers macro molecular structure of synthetic polymer fibres, including their interaction with water.

Ancillary processes are covered, followed by a section detailing the various dyes and methods to impart colour to the more commonly encountered synthetic fibres.

This course will focus on the more commercially important synthetic fibres, namely, polyester (PES), polyamide (PA) and polyacrylonitrile (PAN), as well as the two derivatised cellulosic fibres, cellulose acetate (CA) and cellulose triacetate (CTA).
