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.

Natural dyes are dyes or colorants derived from plants, invertebrates, or minerals. The majority of natural dyes are vegetable dyes from plant sources. Dyeing is the process of imparting colors to a textile material. Different classes of dyes are used for different types of fiber and at different stages of the textile production process, from loose fibers through yarn and cloth to completed garments. There are technologies that manufacture the pigments for plastics, rubber and cosmetics. Therefore; dyes and pigments have a vast area of applications and have a huge demand in industry. Contrary to popular opinion, natural dyes are often neither safer nor more ecologically sound than synthetic dyes. They are less permanent, more difficult to apply, wash out more easily, and often involve the use of highly toxic mordant. Of course, the colour possibilities are far more limited; the color of any natural dye may be easily copied by mixing synthetic dyes, but many other colors are not easily obtained with natural dyes. However, some mordant are not very toxic, and the idea of natural dyestuffs is aesthetically pleasing. Applying natural dyes in your fabric production using enzymes will reduce your production cost and improve control. There are various kind of natural dyes; quinonoid dyes, cyanine dyes, azo dyes, biflvonyl dyes, omochromes, anthraquinone, coprosma gesus etc. The use of natural dyes in cloth making can be seen as a necessary luxury to trigger off a change in habits. Dyes which stand out for their beauty and ecological attributes would never be employed on just any material but on noble fabrics such as wool, silk, linen or cotton, made to last more than one season. Market value will benefit from consumer preferences for environmentally friendly products, which will support consumption of high performance dyes and organic pigments. This book basically deals with the use of carotenoids as food colours , bianthraquinones and related compounds, intermediate degradation products of biflavonyls, dyestuffs containing nuclear sulphonic and carboxylic acid groups, quinonoid dyes, cyanine dyes, optical whitening agents, natural dyes for food, stability of natural colourants in foods effect of additives, pyrimidine pigments, the total synthesis of the polyene pigments, red pigment from geniposidic acid and amino compound, effect of acid and amine on the formation of red pigment from geniposidic acid, effect of the substituted position of amino group and chain length of amino compound etc. Due to pollution problems in synthetic dyes and pigments industry, the whole world is shifting towards the manufacturing of natural dyes and pigments. The present book contains techniques of producing different natural dyes and pigments, which has huge demand in domestic as well as in foreign market. It is hoped that entrepreneurs, technocrats, existing units, institutional libraries will find this book very useful.

In the last two decades the EPA and other national andinternational agencies have placed increasingly strict regulationson the manufacture and use of synthetic colorants. The pigment anddye industry has had to develop the technology necessary to analyzeand remediate pollutants in wastewater. Although these efforts haveproduced a considerable volume of information, until now, no singlebook has provided an organized, comprehensive treatment of theenvironmental chemistry of synthetic colorants. Environmental Chemistry of Dyes and Pigments is the firstcomprehensive reference to address the environmental problems posedby synthetic colorants, and to provide a forum for the solutionsproposed by industry, government, and academia. Focusing ondevelopments in the field over the past two decades, it deals withall aspects of colored wastewater treatment, the disposal of dyes,analytical methods, toxicity, and regulatory questions. In its coverage of wastewater treatment, this book addresses boththe most commonly used methods and those specifically designed toaddress pollution problems at the source by analyzing for andremoving dyes and pollutants from wastewater effluent. Throughout,real-world data on a wide variety of dyes and dye intermediates isprovided, as well as cost-effective strategies for dealing withwastewater treatment. In addition, several chapters are devoted to the perspectives ofnational and international experts on regulations governing themanufacture, handling, use, and disposal of synthetic dyes andpigments. The impact these regulations have had on both U.S. andforeign industry is also discussed. A complete, comprehensive, and up-to-date guide to pollutionprevention in the dyestuff and textile industries Environmental Chemistry of Dyes and Pigments is the onlyself-contained volume that focuses on the environmental impact ofsynthetic dyes and pigments. Contributions by international expertsfrom industry, academia, and government make this an indispensablebook for anyone dealing with the environmental problems posed bysynthetic colorants. It covers the entire range of environmentalissues, from waste treatment and analysis to pollution preventionand government regulations. Covers the latest wastewater treatment methods Shows how to use recycling and reusing methods effectively, whilecutting production costs Describes state-of-the-art technology, including the PACT(r)system Explains analysis techniques, including spectrometry andionization Covers legislative issues and the regulatory status of variouscompounds in both the United States and abroad Examines the various pollution prevention programs instituted bygovernment and industry Bridging the gap between industrial interests and environmentalconcerns, Environmental Chemistry of Dyes and Pigments stands as aninvaluable resource for scientists, researchers, and engineers inthe textile and dyestuff industries, and in the environmentalsciences.

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 are substances that impart colour to a material. The term colorant is often used for both dyes (also called dyestuffs) and pigments. The major difference between dyes and pigments is solubility (the tendency to dissolve in a liquid, especially water). Dyes are usually soluble -- or can be made to be soluble -- in water. Once a dye is dissolved in water, the material to be dyed can be immersed in the dye solution. As the material soaks up the dye and dries, it develops a colour. If the material then retains that colour after being washed, the dye is said to be colourfast. Pigments are generally not soluble in water, oil, or other common solvents. To be applied to a material, they are first ground into a fine powder and thoroughly mixed with some liquid, called the dispersing agent or vehicle. The pigment-dispersing agent mixture is then spread on the material to be coloured. As the dispersing agent dries out, the pigment is held in place on the material. In most cases, dyes are used for colouring textiles, paper, and other substances, while pigments are used for coloring paints, inks, cosmetics, and plastics. This book presents new and significant research from around the world in this field.

Colour is all around us; we take it for granted as a naturally occurring element of all things. Yet colours are also manufactured, and the science of pigments, hues and dyes has an ancient and fascinating history. This book surveys the story of dyes and pigments, the invention of new colours and the industries that were fuelled by them. What were the colours of ancient Egypt? What did its artists use to paint their magnificent frescoes? Where do indigo and ochre come from? Why is purple the colour of royalty? What are pastels? How many colours are there? Why do we dye our food? Who invented ink? What is the symbolism of yellow? From cerise to crimson, from puce to periwinkle, this book is as rich, varied and delightful as a box of crayons.
