The dyeing of natural and synthetic fibres by methods based on modern chemical technology is increasingly becoming an international industry, with countries throughout the world developing and operating textile coloration plants. Many people begin their careers in textile coloration with only a basic knowledge of science and technology, with students typically embarking on demanding courses unsure of some of the more elementary principles involved. This book is designed for such people, as it assumes that the reader has only a basic knowledge of science and mathematics. It offers a thorough all-round appreciation of the fascinating field of textile coloration. It also provides the junior undergraduate with an excellent preparation prior to undertaking more advanced studies.
