The alarming level of greenhouse gases in the environment, fast depleting natural resources and the increasing level of industrial effluents, have made every single manufacturing activity come under the scrutiny of sustainability. When all kinds of waste such as clothes, furniture, carpets, televisions, shoes, paper, food wastes etc. end up in the landfill, only a few of them are naturally decomposed and thus a large majority remains as non-biodegradable. It is for this reason, efforts are concentrated to reduce the burden on earth by this waste, and as far as used textile products are concerned, there are now attempts to recycle or up-cycle. This book addresses the role of sustainability by using textile waste in fashion and textiles with respect to manufacturing, materials, as well as the economic and business challenges and opportunities it poses. This wide-ranging book comprises 19 chapters on the various topics including: · Solutions for sustainable fashion and textile industry · Agro and bio waste in the fashion industry · Innovating fashion brands by using textile waste · Waste in handloom textiles · Business paradigm shifting: 21st century fashion from recycling and upcycling · Utilization of natural waste for sustainable textile coloration · Circular economy in fashion and textile from waste · Future pathways of waste utilization for fashion · Sustainable encapsulation of natural dyes from Plant waste for textiles · Agro-waste applications for bio-remediation of textile effluent

Natural dyes offer a time-tested and generally more sustainable alternative to synthetic dyes in the textile industry. The issues surrounding synthetic dyes are well-known, and in the literature it is generally accepted that natural dyes have a smaller environmental impact. However, even natural dyes have issues that must be dealt with in order to ensure sustainability in the industry. For example, the mordants needed to improve the dyeing process may release hazardous heavy metal pollutants when used. This book is dedicated to exploring cases such as this that illustrate the benefits and drawbacks to natural dyes and steps that must be taken for their sustainable use in the textile industry.

Dyeing is the process of imparting colors to a textile material. Natural dyes are friendly and satisfying to use. They are obtained from sources like flowers, leaves, insects, bark roots etc. however, they are not readily available and involve an extraction process. With the advancement of chemical industry, all finishing procedures of textile materials have been growing constantly and, sustainable and ecological production techniques have become extremely crucial. This is a single book which has information related to extraction of dyestuff from 19 common flowers, weeds, bark or leaves and its application on cotton silk and wool fabrics for textile industry. The Handbook describes the step wise methodology of extraction, mordanting, dyeing with photos of the actual plants part used for extraction of Natural dye. Shade cards have been incorporated so that the full gamut of colors can be visualized from each dyestuff. Major contents of the book are nature of material to be dyed, history of natural dyes, promotion of natural dyes, sources of natural dyes, mordanting the textiles for natural dyeing, quality standards for vegetable dyes, methods of dye extraction, dyeing methodology, chemistry of dye, some recent publications on natural dyes.
