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.
