Book Description
Color, which contributes so much to the beauty of nature, is vital to the attraction and acceptability of most products used by modern society. As early as the 25th century BC, people used a limited range of natural colorants from both animal (e.g., cochineal) and vegetable (e.g., indigo, curcumin, alizarin, Tyrian purple) sources to color their surroundings and clothing. Dyes are substances that, once applied to a substrate, selectively reflect or transmit incident daylight. Most natural dyes are found in the roots, barks, leaves, bracts, flowers, skins, and shells of plants. They are classified as either organometallic or organic compounds, typically exhibiting low solubility in organic solvents. As a result, they generally remain in the solid state during processing and when applied to substrates. This book provides a comprehensive overview of the chemistry and physics of dyes and their intermediates. Chapters address such topics as chemical constituents, spectroscopic aspects, surface, solution, crystal formation, photochemistry, and their ecological and biological properties. This volume will appeal to a wide range of researchers and graduate students worldwide whose work involves dye synthesis, imaging, sensors, energy, medicine, polymers, food products, toxicological properties, and more.

Book Description
This long-awaited guide serves as a tool to explain the general principles of natural dyeing, and to help dyers to become more accomplished at their craft through an increased understanding of the process. Photos of more than 450 samples demonstrate the results of actual dye tests, and detailed information covers every aspect of natural dyeing including theory, fibers, mordants, dyes, printing, organic indigo vats, finishing, and the evaluation of dye fastness. Special techniques of printing and discharging indigo are featured as well. The book is intended for dyers and printers who wish to more completely understand the "why" and the "how," while ensuring safe and sustainable practices. Written by a textile engineer and chemist (Boutrup) and a textile artist and practitioner (Ellis), its detailed and tested recipes for every process, including charts and comparisons, make it the ideal resource for dyers with all levels of experience.

Book Description
This book provides an up-to-date insight into the chemistry behind the colour of the dyes and pigments that make our world so colourful. The impressive breadth of coverage starts with a dip into the history of colour science. Colour Chemistry then goes on to look at the structure and synthesis of the various dyes and pigments, along with their applications in the traditional areas of textiles, coatings and plastics, and also the ever-expanding range of "high-tech" applications. Also discussed are some of the environmental issues associated with the manufacture and use of colour. The broad and balanced coverage presented in this book makes it ideal for students and graduates. In addition, many specialists in industry or academia will also benefit from the overview of the subject that is provided.

Book Description
Natural Dyes for Textiles: Sources, Chemistry and Applications is an in-depth guide to natural dyes, offering complete and practical coverage of the whole dyeing process from source selection to post-treatments. The book identifies plants with high dye content that are viable for commercial use, and provides valuable quantitative information regarding extraction and fastness properties, to aid dye selection. The book presents newer natural dyes in detail, according to their suitability for cotton fabrics, silk fabrics, and wool yarn, before describing the application of each dye. Extraction of plant parts for isolation of colorants, chromatographic techniques for separation, spectroscopic analysis of the isolated colorants, structure elucidation, biomordanting, pretreatments, and post-treatments, are also covered. Prepared by an expert author with many years of experience in researching and writing on natural textile dyes, this book is an important resource for academic researchers, post-graduate students, textile manufacturers, technicians, dye practitioners, and those involved in textile dye research and development. - Written by an expert author with many years of experience in researching and writing on natural textile dyes - Provides quantitative information about extraction and fastness properties that will be valuable to those involved in dye selection - Offers complete and practical coverage of the whole dyeing process from source selection to post-treatments

Book Description
Handbook of Natural Colorants Second Edition A detailed survey of a variety of natural colorants and their different applications including textiles, polymers, and cosmetics Colorants describe a wide range of materials such as dyes, pigments, inks, paint, or chemicals, which are used in small quantities but play an important role in many products such as textiles, polymers, food, and cosmetics. As the effects of climate change begin to be felt, there has been a shift in focus in the field to renewable resources and sustainability, and an interest in the replacement of oil-based products with greener substitutions. As the push to adopt natural resources grows, there have been significant developments in the research and application of natural colorants as a step in the transition to a bio-based economy. The second edition of Handbook of Natural Colorants provides a detailed introduction to natural colorants in a marriage of theory and practice, from seed of plant to consumer demand. Presenting a wide range of viewpoints, the book briefly discusses the history of coloration technology and the current position of natural colorants before highlighting detailed information on regional plant source availability, colorant production and properties, as well as analytical methods for isolation, identification, and toxicity aspects. It also presents key applications in technical use and consumer products, including the use of natural colorants in textiles, hair dyeing, printing, and packaging. Finally, the text considers environmental and economic aspects of natural colorants. Handbook of Natural Colorants is a useful reference for dyers, textile producers, and researchers in the evolving field of sustainable chemistry, environmental sciences, agricultural sciences, and polymer sciences. Revised and updated content throughout to reflect developments in research and applications over the past decade New content on biotechnology in natural colorant production, natural colorants for mass coloration polymers, natural colorants in printing/packaging, and plant-based pigments Discusses strategies for scale-up, including consideration of energy, waste, and effluents For more information on the Wiley Series in Renewable Resources, visit www.wiley.com/go/rrs
