New Trends in Natural Dyes for Textiles addresses 20 natural dyes that are finding innovative uses in industry and academia. It comprehensively addresses issues relating to natural dyes and dyeing problems, including efficient extraction and standardization of dyes, dyes structure, dyes characterization and identification. Readers working in the dyeing of textiles will learn how to improve practices to minimize environmental pollution, avoid bad dyeing, and select the best mordants to fix colorant compounds. Key benefits of natural dyes over synthetic are examined in detail, providing readers with an understanding of the importance of natural dyes and the proper methods for applying them.

Provides suitable extraction processes for each of the 20 dyes described Offers complete and practical coverage of the whole dyeing process, from source selection to post-treatments Covers practical advice on the application of these dyes to cotton, silk and wool

Natural Dyes for Sustainable Textiles describes how manufacturing processes that are safer, more energy efficient, and more sustainable can be achieved through the use of natural dyes.There are three main elements of sustainability, they are: economic, social, and environmental, and natural dyes can make a positive contribution to all three. A number of the textile industry's largest producers have adopted natural dyes as part of their bid to make their products more sustainable, in response to consumer demand as well as their own consciousness of environmental issues. This unique book draws on the latest research to provide practical technical advice on safer and greener processing of fabric, minimizing the use of hazardous chemical dyes. Details of preparation methods at stages including wet processing, dyeing, and effluent management are provided with specific information on how the methods improve efficiency, as well as other advantages and limitations of each technology. Provides case studies of how to switch from synthetic to natural dyes, and what benefits resulted in real life Describes a practical chemical management system, which involves natural dyes Examines use of high-tech methods such as plasma and electron beam in textile surface modification

Special Techniques of Natural Dyeing using Mordants and Modifiers explores the development of special auxiliaries that enhance the colorfastness, color depth, and sustainability of naturally dyed fabrics that maintain low carbon footprints. Key topics include chapters on mordants, bio-mordants, transitional metal salts, and rare earth salts. Additionally, the book covers various modifiers and auxiliaries designed to improve color adherence, as well as a chapter dedicated to post-mordanting treatments with amino compounds. Natural dye enthusiasts will gain valuable insights into using mordants sustainably, achieving vibrant, long-lasting colors from common flowers and other local vegetative materials.Provides details on the chemistry of natural dyeing and the importance of mordantsExplores new auxiliaries and mordants that enhance dyeing resultsEmphasizes the use of sustainable additives for natural dyeing
