Physico-chemical Aspects of Textile Coloration
John Wiley & Sons Inc (Verlag)
978-1-118-72569-6 (ISBN)
Physico-Chemical Aspects of Textile Coloration provides a comprehensive treatment of the physical chemistry involved in the dyeing of the major types of natural, man-made and synthetic fibres with the principal types of dye. The book covers:
fundamental aspects of the physical and chemical structure of both fibres and dyes, together with the structure and properties of water, in relation to dyeing;
dyeing as an area of study as well as the terminology employed in dyeing technology and science;
contemporary views of intermolecular forces and the nature of the interactions that can occur between dyes and fibres at a molecular level;
fundamental principles involved in dyeing theory, as represented by the thermodynamics and kinetics of dye sorption;
detailed accounts of the mechanism of dyeing that applies to cotton (and other cellulosic fibres), polyester, polyamide, wool, polyacrylonitrile and silk fibres;
non-aqueous dyeing, as represented by the use of air, organic solvents and supercritical CO2 fluid as alternatives to water as application medium.
The up-to-date text is supported by a large number of tables, figures and illustrations as well as footnotes and widespread use of references to published work. The book is essential reading for students, teachers, researchers and professionals involved in textile coloration.
Professor Stephen Burkinshaw is a Professor of Textile Chemistry at the University of Leeds. His research interests include the chemistry and application of dyes and pigments to natural and man-made fibres, colour measurement and textile finishing. He is the author of ~200 publications including a textbook on dyeing theory (Chemical Principles of Synthetic Fibre Dyeing, Springer, 1995.) and section editor for the Springer publication, Encyclopedia of Colour Science and Technology, which is due for publication in 2013. As both a tutor of part-time students sitting ASDC Paper C: Properties of Materials and Finished Products and Fundamental Mechanisms of Industrial Processes and examiner of ASDC Paper C (1994-1999), as well as the person responsible for teaching and examining all three undergraduate years in Dyeing Theory within the Department of Colour Science at Leeds University, Professor Burkinshaw has first-hand, tangible experience of how students view and use this particular book.
