This long-awaited guide serves as a tool to explain the general principles of natural dyeing, and to help dyers to become more accomplished at their craft through an increased understanding of the process. Photos of more than 450 samples demonstrate the results of actual dye tests, and detailed information covers every aspect of natural dyeing including theory, fibers, mordants, dyes, printing, organic indigo vats, finishing, and the evaluation of dye fastness. Special techniques of printing and discharging indigo are featured as well. The book is intended for dyers and printers who wish to more completely understand the "why" and the "how," while ensuring safe and sustainable practices. Written by a textile engineer and chemist (Boutrup) and a textile artist and practitioner (Ellis), its detailed and tested recipes for every process, including charts and comparisons, make it the ideal resource for dyers with all levels of experience.

Natural Dyes : Scope and challenges is a comprehensive, thoroughly scientific, single source reference book on natural dye stuffs and dyeing. This book provides a detailed chemistry of all the available natural dyes and also of the food colors. Analytical methods including extraction, identification and estimation of the chemical components of these dyes, which will help in the production of quality dyes, are discussed. The applications of these dyes in pharmaceuticals, herbal cosmetics, paints and paintings also are explained. The challenges lying ahead due to the greater demand resulted from the ever-increasing acceptance and demand of these dyes and their solutions are discussed. Substitute sources, new chromophores, bioactivities including antioxidant potential and antimicrobial properties of the plant-derived dyes also are dovetailed. This book will serve as a reference book for students, teachers and workers of Textile dyeing, Textile chemistry, Clothing and textiles, Plant Sciences, Pharmacy and Fine Arts. It will also of great use for NGOs and farmers who would be interested in value-addition of their trees, commercial manufacturers of natural dyes and even to a layman interested in natural colors. D.

"For several thousand years, all dyes were of animal, vegetable, or mineral origin, and many ancient civilizations possessed excellent dye technologies. The first synthetic dye was produced in 1856, and the use of traditional dyes declined rapidly thereafter. By 1915 few non-synthetics were used by industry or craftspeople. The craft revivals of the 1920s explored traditional methods of natural dyeing to some extent, particularly with wool, although the great eighteenth- and nineteenth-century dye manuals, which recorded the older processes, remained largely forgotten. In The Art and Craft of Natural Dyeing, J.N. Liles consolidates the lore of the older dyers with his own first-hand experience to produce both a history of natural dyes and a practical manual for using pre-synthetic era processes on all the natural fibers--cotton, linen, silk, and wool. A general section on dyeing and mordanting and a glossary introduce the beginner to dye technology. In subsequent chapters, Liles summarizes the traditional dye methods available for each major color group. Scores of recipes provide detailed instructions on how to collect ingredients--flowers, weeds, insects, wood, minerals--prepare the dyevat, troubleshoot, and achieve specific shades"--Publisher's description.

This book describes some 300 plants and 30 animals (marine mollusks and scale insects) that are used as sources for natural dyes. Botanical or zoological details are given for each source and the chemical structures is shown for each dye. Dyes employed by different civilisations, identified by dye analyses, are illustrated and relevant historical recipes and detailed descriptions of dyeing processes by traditional dyers are quoted and explained in the light of modern science. Other current uses of natural colorants, e.g. in medicine and for food and cosmetics, and replacement of synthetic by natural dyes are also noted.

With the public enhanced awareness towards eco-preservation, eco-safety and health concerns, environmentally benign, nontoxic and sustainable bioresource materials produced mainly from non-food crops have revolutionized all industrial sectors particularly textile industry. In recent years, textile industries in developed countries are getting increasing interest in global interest due to the varied and changing world market conditions in terms of price, durability and fiber mixtures as well as design, colors, weight, ease of handling and product safety. The increasing environmental and health concerns owing to the use of large quantities of water and hazardous chemicals in conventional textile finishing processes lead to the design and development of new dyeing strategies and technologies. Effluents produced from these textiles wet processing industries are very diverse in chemical composition, ranging from inorganic finishing agents, surfactants, chlorine compounds, salts, total phosphate to polymers and organic products. This aspect forced western countries to exploit their high technical skills in the advancements of textile materials for high quality technical performances, and development of cleaner production technologies for cost effective and value-added textile materials. Therefore, vast and effective research investigations have been undertaken all over the world to minimize the negative environmental impact of synthetic chemical agents through the sustainable harvest of eco-friendly bioresource materials. The book will discuss following research developments in academic and industry: Improvement in dye extraction and its applications Impact of textile dyeing on environment Textile finishing by natural and ecofriendly means Natural dyes as environmental-friendly bioresource products Textile effluent remediation via physical, chemical and biological processes.
