Synthetic fibres are widely used for many applications, with their colour being of major commercial importance. This extensively referenced book provides a comprehensive account of the physical chemistry of the dyeing of synthetic fibres and microfibres.

The production of textile materials comprises a very large and complex global industry that utilises a diverse range of fibre types and creates a variety of textile products. As the great majority of such products are coloured, predominantly using aqueous dyeing processes, the coloration of textiles is a large-scale global business in which complex procedures are used to apply different types of dye to the various types of textile material. The development of such dyeing processes is the result of substantial research activity, undertaken over many decades, into the physico-chemical aspects of dye adsorption and the establishment of ‘dyeing theory’, which seeks to describe the mechanism by which dyes interact with textile fibres. 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.

Chromic phenomena, or those produced by materials which exhibit colour in response to a chemical or physical stimulus, have increasingly been at the heart of 'high-tec' developments in a variety of fields in the last decade. Many of the newer technologies, which are at the cutting edge of research, are multi-disciplinary, involving researchers from areas as diverse as physics, biology, materials science and electronic engineering. Chromic Phenomena covers five main areas: * Colour change materials, such as photochromic, thermochromic and electrochromic materials * Materials which absorb and reflect light - the classical dyes and pigments * Luminescent phenomena, including phosphorescence, fluorescence and electroluminescence * Materials which absorb light and transfer energy, eg photosensitisers, infra-red absorbers and laser-addressable compounds * Phenomena involving the manipulation of light by chemicals, such as liquid crystals, lustre pigments, optoelectronics and photonics Providing an entry point both for new researchers and for established ones, this book, with its emphasis on the technological applications of these chromic phenomena, develops and investigates new applications for colour chemistry. It will be of interest to industrialists and professionals in the biological, medicinal, electronics/telecommunications and colorant industries, as well as academics in these fields.

At the beginning of this series of volumes on Color Chemistry, the editors pointed to a number of events that have served as stimuli for techno logical advances in the field, thus preventing dyestuff manufacturing from becoming what might otherwise be viewed by now as a 'sunset industry'. The volumes which followed have provided ample evidence for our belief that the field of colour chemistry is very much alive, though arguably in need of further stimulus. For instance, a viable approach to the design of new chromophores and to the design of metal-free acid, direct, and reactive dyes having fastness properties comparable to their metallized counterparts represent the kind of breakthroughs that would help ensure the continued success of this important field. While it must be acknowledged that serendipity 'smiled' on our discipline at its inception and has repeated the favor from time to time since then, few would argue against the proposition that most of the significant advances in the technology associated with any scientific discipline result from research designed to enhance our understanding of the fundamental causes for experimental observations, many of which are pursued because they are unexpected, intriguing and intellectually stimulating. Little reflection is required for one who knows the history of the dyestuff industry to realize that this is certainly true in the colour chemistry arena, as it was basic research that led to fiber-reactive dyes, dyes for high technology, and modern synthetic organic pigments.

An Introduction to Textile Coloration: Principles and Practice The Publications Committee of the Society of Dyers and Colourists (SDC) has been aware for some time of the need to produce a book at an introductory level aimed at personnel working in textile dyeing or printing companies as well as those interested in entering into the field. The SDC runs a course for dyehouse technicians leading to the award of its Textile Coloration Certificate and this book is intended to be helpful for candidates following the course. Additionally, it will be helpful for professionals in textile companies who do not have a strong scientific background, so that they may attain a better understanding of the chemical principles of colour application. Starting with the basic science underlying dyeing and printing processes, this comprehensive book explains the fundamentals of dye and pigment chemistry and the various application techniques and processes. It offers chapter coverage of the general chemistry related to textiles, textile fibres, chemistry of dyes and pigments, industrial coloration methods, textile printing, theoretical aspects of dyeing, the measurement of colour and fastness testing. Reference is made to developments that have taken place in the coloration industry in recent years, not least of which have been the challenges imposed by the drive towards environmentally-friendly processes and restrictions on the use of certain chemicals. An Introduction to Textile Coloration: Principles and Practice Covers atomic structure, chemical reactions, and acids, bases, and salts Explains the nature of fibre-forming polymers and the conversion of synthetic polymers into fibre filaments Educates on the classification of colorants and the commercial naming of dyes and pigments Introduces readers to the dye application processes and dyeing machinery Instructs on dye aggregation, factors affecting colour appearance, the principles of colour fastness testing, and more
