Textile Processing with Enzymes

As the need to reduce pollution in textile production increases, the use of enzymes in the chemical processing of fibres and textiles is rapidly gaining recognition for its eco-friendly and non-toxic characteristics. Enzymes are a safe alternative in a wide range of textile processes that would otherwise require harsh chemicals whose disposal would pose environmental problems. Textile Processing with Enzymes covers all of the relevant issues from basic biochemistry and enzymology to the industrial application of these biocatalysts. The book begins with the fundamental aspects of enzymes determining catalytic properties, followed by a summary of fibrous and non-fibrous materials as substrates for enzymes. It discusses catalysis and processing, with an overview of the function and application of enzymes used in textile processing, and addresses process engineering and industrial enzyme applications. The final chapters present the practical aspects of handling enzymes, provide a detailed look at operational and storage stabilities, and consider the use of enzymes in effluent treatment. As a comprehensive guide to textile processing with enzymes, this book explains the applications that are transforming the industry. It is a valuable resource for scientists and engineers with a basic background in textiles, biotechnology, chemistry, or engineering, as well as students interested in the subject.
