Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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

Book excerpt: 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.

This book was released on 2005-10-04 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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.
