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.

Dyes and pigments have been utilized since ancient times. They play an important role in everyday life and their use is interwoven with human culture. Even though numerous dyes and pigments have been synthesized to date, and a lot of knowledge has been gained regarding their production and properties, scientific research is pushing the boundaries towards novel dyes and pigments for high-tech applications. At the same time, the accumulation of dyes and pigments in natural environments and pollution of water resources due to their massive use are important consequences to consider. New methods for the degradation and removal of dyes and pigments from affected areas are highly sought after. As such, this book examines new trends in smart and functional dyes and pigments and their uses as well as novel treatment approaches to dye and pigment waste.

"How did textile dyers manipulate the natural dyes at their disposal to obtain the colours we see on fabrics and tapestries in museum collections today? How did colour makers prepare the translucent lake pigments used by artists to give richness and volume to painted draperies and subtle modulations of colour and space in the depiction of landscape? Some of the technological factors the dyer or pigment maker could control very easily have a marked effect on the final colour: the mordant salt used on the textile fibre; the temperature at which the dye was extracted from the raw material or dyeing was carried out; the method of extracting the during pigment preparation. These factors were explored as part of a research activity within the European project CHARISMA (Cultural Heritage Advanced Research Infrastructures -- Synergy for a Multidisciplinary Approach to Conservation/Restoration), a Research Infrastructures project founded by the European Union 7th Framework Programme (2009-2014, grant agreement no. 228330). Recipes for dyeing and lake pigment making using natural dyes, based on those found in historical documentary sources, were designed to study the effects of these and other factors and used during two CHARISMA workshops held in 2011 -- one on making traditional lake pigments, the other on dyeing. This book brings together the recipes used during these very successful workshops with discussions of the historical recipes upon which they were based and is illustrated with photographs taken during the workshops. The most widely used European natural dyes are described briefly and a short account of the chemistry of dyeing and lake pigment is included. The book is aimed primarily at those who need easily modified and reproducible recipes for teaching or scientific work: conservators, scientists and teachers." -- Provided by publisher

Years of human ignorance has diminished our natural resources and aged our planet. Now, people are making an effort to change the way they are treating the planet. Being more environmentally conscious about the impact materials used for fashion have on our planet is one-way designers can reduce waste and help enable a better world. By going eco-friendly can be less harmful to our natural resources. Not all fashion is following this eco-friendly trend, but more designers are embracing the trend toward eco-fashion than ever before. If the entire fashion industry became eco-friendly, it would make a huge difference for future generations because the fashion industry employs over a billion people globally. There is need for eco-friendly wet processing that is sustainable and beneficial methods. Number of sustainable practices has been implemented by various textile processing industries such as Eco- friendly bleaching; Peroxide bleaching; Eco-friendly dyeing and Printing; Low impact dyes; Natural dyes; Azo Free dyes; Phthalates Free Printing. There are a variety of materials considered "environmentally-friendly" for a variety of reasons. The industry is desperately in the need of newer and very efficient dyeing/finishing and functional treatments of textiles. There is growing awareness and readiness to adapt new perspective on industrial upgradation of Cleaner Production Programme, such new technologies help enterprises achieve green production and cost reduction at the same time. Green Production has become necessary for enterprises under the upgrade and transformation policy. The book Eco-Friendly Textile Dyeing and Finishing covers topics in the area of sustainable practices in textile dyeing and finishing.

Textile Dyes and Pigments The book covers the best possible innovation and advancement in dyes and pigments for application in textile materials. Green chemistry can be applied across the life cycle of a chemical-intensive product, including its design, manufacture, use, and ultimate disposal. Innovations to green approaches are required either by developing a whole new set of eco-friendly dyes and pigments or by developing and designing unique dyeing methods. Textile Dyes and Pigments: A Green Chemistry Approach is a response to the many industries currently using conventional textile dyeing and pigmentation methods that are looking for sustainable green chemical options. It describes the various organic and inorganic color pigments and recent developments in vat, reactive, disperse, acid, and azo dyes and their importance in the field of green chemistry. It also covers the various challenges, opportunities, approaches, techniques, marketing, and alternative procedures/sustainable routes involved in developing textile dyes and pigments with green practices. Moreover, the book addresses the structure, process, and the nitty-gritty of modern dyes and pigments in the textile and garment sectors. Audience The book will be of prime interest to researchers and industry manufacturers and engineers in dyes, pigments, textile processing technology, fiber technology, and textile chemistry. It will also be an invaluable reference guide to new scholars and industry personnel who wish to learn about green dyes and pigments and their relevant application processes.

Textile dyes enhance our environment, bringing colour into our lives. The current range of dyes have been developed to withstand environmental effects, such as degradation by exposure to light and water. However, the industry involved with the application of dyes to textiles has a responsibility to ensure that potential for harm to the environment, for example through residues in waste-streams, and to the consumer is minimised. Written by an international team of contributors, this collection reviews current legislation and key technologies which make textile dyeing more efficient and environmentally friendly.The book begins by detailing European and US legislation relating to textile dyeing. Further chapters cover toxicology, environmentally responsible application of dyes and supercritical fluid textile dyeing. The book concludes with chapters on the reduction of pollution and minimisation of waste, the re-use of spent dyebath, chemical treatment of dye effluent and biotechnological treatment of dye effluent.Environmental aspects of textile dyeing is a standard reference source for manufacturers concerned with developing a sustainable industry. - Crucial guide to minimising harmful effects on environment and the consumer - Reviews current technologies and European and US legislation - Essential for all textile manufacturers
