Physico Chemical Aspects Of Textile Coloration

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.

This is a comprehensive book that imparts technological skills about the colouration of textiles. It discusses academic as well as shop-floor aspects of colouration. It also covers eco-friendly enzymatic processing and differential coloured effects.

"This book is the final integration of a series of 24 papers [...] which were published in Textile Chemist and Colorist between October 1991 and November 1993"--Preface.

The type and amount of textile products have greatly proliferated over the last decade. Concomitant textile processing to improve the properties and ultimate performance has also undergone dramatic changes. Ready availability of instrumentation, computers, lasers and integration of these advances with similar progress in polymer/material science have led to the need for a unified discussion on these topics. The current book concisely discusses all aspects of textile processing, modification and performance for four major topics: preparation (by fiber type), dyeing and printing (dye type, theory and synthesis; dye classification by structure and application), improving functional and aesthetic textile properties (physical, chemical and physicochemical processes and concepts), and performance (chemical analysis, instrumental methods; physical, chemical, biological, multiple influences and standard tests). A detailed and logical progression from the initial purification of textiles to their performance and care is described. The book will be useful as a text for textile/polymer courses at undergraduate and graduate levels and as a comprehensive source of information for textile scientists, engineers, manufacturers, retailers and others with an interest in textile products.

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

Keratin fibres, particularly wool fibres, constitute animportant natural raw material in textiles due to their comfort andthermal proprieties. Wool coloration demands an understanding ofthe complex nature of the interplay between wool fibre chemistry,morphology and the coloration processes. The Coloration of Wool and other Keratin Fibres is acomprehensive treatment, written by leading international experts,of the chemistry and chemical processes involved in wool dyeing,printing, preparation and finishing. The book covers: the chemical and physical structure of wool keratin fibres,detailing their complex heterogeneity and the subtle links betweenfibre structure and dyeability the coloration of fabrics containing wool, including a varietyof wool blends such as wool/silk, wool/polyester and wool/cotton,and luxury keratin fibres such as mohair, cashmere and camel the chemistry of the various types of dyes utilised in wooldyeing and in-depth discussions on the physical properties tooptimise these processes practical application of dyes to wool in all its forms, loosestock, combed tops, yarns and piece goods, is covered in thechapter on wool dyeing machinery two chapters, one on bleaching and whitening and one on dyeinghuman hair, provide a valuable extension to the topic of cosmeticchemistry The Coloration of Wool and other Keratin Fibres isessential reading for professionals world-wide working in companiesinvolved in the dyeing and printing of wool, wool blends and otherkeratin fibres and also for the producers of dyes and auxiliarydyeing agents. It is a valuable resource for teachers and studentsof universities and technical institutes, as well as forresearchers who are focusing their investigations on wool, woolblends, human hair or dyes and auxiliaries.
