Renewable Dyes and Pigments takes an interdisciplinary approach to bridging the gap between established knowledge of traditional natural dyes and pigments and their emerging aspects in various rapidly growing industrial sectors. Research into new natural dye and pigment sources along with the discovery of sophisticated instrumentation and technology for their processing, characterization, and applications has greatly assisted in widening their scope in various advanced application disciplines is covered, along with information on a number of synthetic dyes and their detrimental effects on the environment and associated allergic, toxic, carcinogenic, and harmful responses. Amidst growing environmental and health concerns, eco-friendly, non-toxic dyes and pigments from renewable materials have re-emerged as a potential viable, sustainable option as an alternative or co-partner to synthetic compounds. This book covers a wide range of topics related to the chemistry and applications of natural dyes and pigments, with an emphasis on recent technological developments in textile dyeing, the food sector and the use of natural pigments in dye-sensitized solar cells, and more. - Covers sources, chemistry and processing of dyes and pigments from renewable sources using advanced techniques - Summarizes technological developments in textile dyeing and their potential applications in other demanding sectors - Examines and discusses the future of renewable dyes and pigments and outlines the major challenges in creating products and materials for textile, food and DSSC applications
The purpose of this unique handbook is to provide reference material that includes basic principles and current developments in the field of natural coloration and finishing. A sustainable world requires the utilization of renewable materials or resources that can be produced in huge quantities for a wide range of applications. To adopt the use of active materials for textile coloration and finishing, they should reach the technical demands of the modern world such as eco-preservation, economic and ecological requirements by which, equity and sustainability might be considered. Therefore, there is a need to discuss and understand the challenges and solutions of textile coloration and functional finishing methodologies. The 20 chapters comprising the Handbook of Renewable Materials for Coloration and Finishing are divided into four segments: Substrates for Coloration and Finishing; Renewable Colorants and their Applications; Advanced Materials and Technologies for Coloration; and Finishing and Sustainability. Part I contains three chapters that overview the systematic discussion on the suitability, physical, chemical and processing aspects of substrates for coloration and finishing. Part II includes nine chapters and covers in-depth arguments on renewable colorants and their various applications including a chapter on bio-colorant's application as photosensitizers for dye sensitized solar cells. Part III contains five chapters in which modern advancements and processing methods/technologies for coloration and functional finishing are presented comprehensively. Part IV contains two chapters that provide sustainable aspects of coloration and finishing.
In this book the authors go back to basics to describe the structural differences between dyes and pigments, their mechanisms of action, properties and applications. They set the scene by explaining the reasons behind these differences and show how dyes are predominately organic compounds that dissolve or react with substrates, whereas pigments are (predominantly) finely ground inorganic substances that are insoluble and therefore have a different mode of coloring. They also describe the role of functional groups and their effect on dyeing ability, contrasting this with the way in which pigments cause surface reflection (or light absorption) depending on their chemical and crystalline structure and relative particle size. The book explores the environmental impact of dyes in a section that covers the physical, chemical, toxicological, and ecological properties of dyes and how these are used to assess their effect on the environment and to estimate whether a given product presents a potential hazard. Lastly, it assesses how, in addition to their traditional uses in the textile, leather, paper, paint and varnish industries, dyes and pigments are indispensable in other fields such as microelectronics, medical diagnostics, and in information recording techniques.
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
