Extracts from these books will be made available throughout the course to support the videos and transcripts and to provide useful background reading. The links below will take you to the online shop section of the SDC website, where there is an option to purchase.

Physio-chemical aspects of Textile Coloration – Stephen M Burkinshaw, publisher SDC.

Theory of Coloration of Textiles, 2nd Edition – Edited by Alan Johnson. Chapter 4 (Thermodynamics of dye sorption, Harry H. Sumner) and Chapter 5 (Diffusion and rates of dyeing, F. Jones) give a comprehensive account of the essentials of Dyeing Theory.

An Introduction to Textile Coloration: Principles and Practice – Roger H. Wardman, publisher SDC. This book is recommended as a good, accessible overview of the theoretical aspects of dyeing.

Basic Principles of Textile Coloration – Arthur D Broadbent, publisher SDC

This course will cover some of the more important fundamental aspects  of physical chemistry in relation to the Theory of Dyeing

The start of this course is the Welcome which will guide you through the development of the Learning Outcomes and the various ways in which you can enhance your learning by navigating the site, how you can manage your time and how to best revise and prepare for examinations.

This course contains scientific content prepared by experts within their specific field and is developed and delivered by Antony Morton for the Society of Dyers and Colourists. Contact  antonym@sdc.org.uk

The following publication is available to you to help with some of the specific terms and definitions encountered within coloration industries.

  1. The SDC publication “Colour terms and definitions”

To fully appreciate the coloration of all textile fibres there is a need to understand the physical, chemical, thermal and optical properties of fibres in general. The following 4 documents provide this background information that you should refer to during your study. These documents are also useful reference material when you are studying the dyeing of natural fibres.

  1. General Physical and Mechanical properties of Fibres
  2. Mechanical properties of Fibres
  3. Thermal properties of Fibres
  4. Optical properties of Fibres

Extracts from some of the recommended texts as well as articles from Coloration Technology are made available to students in the lessons.

In the following lectures, commercial names of dyes, fibres, auxiliaries etc are provided; this does not imply superiority of commercial products but is intended to serve only as a guide. Similarly while aspects relating to application procedures is presented, these are intended as being representative of typical application conditions only and are not intended to be employed for practical dyeing.
