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.

Download or read book Natural Colorants for Dyeing and Lake Pigments written by Jo Kirby and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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

Download or read book Dyes and Pigments written by Ahmet Gürses and published by Springer. This book was released on 2016-05-04 with total page 88 pages. Available in PDF, EPUB and Kindle. 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.

Download or read book Liquid Chromatography of Natural Pigments and Synthetic Dyes written by Tibor Cserháti and published by Elsevier. This book was released on 2006-12-07 with total page 602 pages. Available in PDF, EPUB and Kindle. Book excerpt: This latest volume in the series entitled Liquid Chromatography of Natural Pigments and Synthetic Dyes presents an overview of the latest developments in the field while critically evaluating this method of analysis and providing comparisons of the various liquid chromatographic separation techniques that are currently available. Natural pigments and synthetic dyes are extensively used in various fields of everyday life including food production, textile industry, paper production, agricultural practice and research and water science and technology. Besides their capacity for increasing the marketability of products, natural pigments have shown advantageous biological activity as antioxidants and anticancer agents. On the negative side, synthetic pigments have a significant impact on the environment and can cause adverse toxicological side effects. Both pigment classes exhibit considerable structural diversity. As the stability of the pigments against hydrolysis, oxidation and other environmental and technological conditions is markedly different, the exact determination of the pigment composition may help for the prediction of the shelf-life of products and the assessment of the influence of technological steps on the pigment fractions resulting in more consumer friend processing methods. Furthermore, the qualitative determination and identification of the pigments may contribute to the establishment of the provenance of the product. The unique separation capacity of liquid chromatographic (LC) techniques makes it a method of preference for the analysis of pigments in any complicated accompanying matrices. * an overview of the latest developments in the field * a critical evaluation of results from this form of analysis * a comparison of the various LC (liquid chromatographic) separation techniques * future trends in the LC analysis of pigments
