Preface

In recent years, the textile industry has been the focus of rising interest in global markets due to varied and changing world market conditions. Increasing environmental and health concerns owing to the use of large quantities of water and hazardous chemicals in conventional textile finishing processes, has led to the design and development of new dyeing strategies and technologies. Effluents produced from the textile wet processing industry are very diverse in chemical composition, ranging from inorganic finishing agents, surfactants, chlorine compounds, salts and total phosphate to polymers and organic products. This has forced Western countries to exploit their high technical skills for the advancement of textile materials with high quality technical performances, and the development of cleaner production technologies for cost-effective and value-added textile materials. Sustainable Practices in the Textile Industry is a collection of the current sophisticated ways used to minimize the use of bioresource products to improve dye extraction and dyeing properties. Highlighted in this book are the innovative ways in which wet chemical processing methods are used to alleviate the environmental impacts arising from this sector. The major challenge in the textiles and fashion sector is that it requires massive sustainable innovation in terms of material and end-use products to mitigate the huge environmental impacts arising from chemical processing. Therefore, this book also contains innovations in eco-friendly methods for textile wet processes and applications of enzymes in textiles in addition to advancements in the use of nanotechnology for wastewater remediation.

The book is compiled of 13 chapters from various research areas dealing with the application of different sustainable technologies for enhancing the dyeing and comfort properties of textile materials with substantial reduction in wastewater problems. Chapter 1 deals with the sustainable extraction of natural dyes from plant sources and their subsequent applications in the textile industry. Chapter 2 deals with the advancements in non-aqueous dyeing systems. Chapter 3 gives a brief account of structural coloration of different textiles achieved as a result of scientific observations of nature. Chapter 4 deals with the use of enzymes for enhancing dyeing properties of different textiles. Chapter 5 deals with the use of sustainable processes for textile coating. Chapters 6 through 8 give a detailed account of the functional finishing properties achieved on different textiles using different dyeing methods with natural and synthetic functional finishing agents. Chapter 9 provides up-to-date information regarding sustainable development for brands and manufacturers in the textile industry. Finally, the remaining Chapters 10 through 13 deal with the advanced techniques used for wastewater remediation.

The authors who contributed to this book are specialists in fields involved in using different dyeing systems other than aqueous solvent, employing enzymes in dyeing procedures, surface modifications, sustainable developments for textile manufactures, functional finishing and different advanced techniques for wastewater remediation. Thus, the editors hope that students, researchers and academicians of various fields, such as textile dyeing, chemical engineering, environmental science, materials science among others, will find this book of great interest and useful in their curriculum. We expect it will definitely be helpful for engendering new ideas in textiles research, leading to interdisciplinary research collaborations.

Now the time has come to thank those who supported this book in any way. We acknowledge the great efforts of the eminent authors without whom this book would have been unimaginable. We also appreciate the interest shown and the support given by the publisher, which allowed us to compile this reference book.
