Book Description
Textile and fibre chemistry form the theoretical basis to understand production and properties of textile based products. In this 2nd edition fundamentals of textile chemistry and theoretical and applicatory aspects of colour chemistry are interconnected to draw detailed picture of chemical reactions occurring during production and modification of textile products. An overview about chemical modification, finishing operations is given to explain how to impart special functionalities into functional products. Examples for technical scale processes and representative machinery used therein give insight into the technical reality of a dyehouse. A new chapter about circularity of textiles highlights the interlinkage between product design, including dyes and finishes, and the requirements to develop future fibre-to-fibre recycling. The work covers all relevant aspects of a textile product from fibre production, coloration, finishing, consumer use and fibre-to-fibre recycling. The content of the book allows a first entry into this multi-disciplinary field. Through its comprehensive character the authors explain the interdependence between textile and fibre processing and aspects of recycling, which makes the work a valuable source of information to design future textiles for circularity.

Book Description
This volume examines the chemistry of natural and synthetic dyes produced for non-textile markets, where much new basic research in color chemistry is now taking place.The first group of chapters covers the design, synthesis, properties and application technology pertaining to dyes for digital printing and photography. The reader will be pleased with the breadth and depth of information presented in each case. Of particular interest is the discussion of strategies for the design of dyes in these categories, with emphasis on enhancing technical properties. In view of certain new developments, the ink-jet chapter includes results from studies pertaining to dyes for textiles.The three chapters comprising Section II of this volume cover the broad subject of dyes for food, drug and cosmetic applications and then provide an in-depth look at dyes for biomedical applications and molecular recognition. The chapter on dyes for molecular recognition places emphasis on applications in the biological sciences, including sensory materials and artificial receptors. While the former two topics have been covered elsewhere in the past, the present chapters are unequalled in scope.Section III provides an in-depth review of the design of laser dyes and dye-based functional materials. In the first of the two chapters, the major principles of laser operation are summarized. This is followed by a discussion of spectroscopic properties, such as activation and deactivation of absorbed light by laser dyes. Approaches to the development of new laser dyes are presented. The second chapter pertains to the synthesis of dicyanopyrazine-based multifunctional dyes. The visible and fluorescence spectra of these dyes in solution and the solid state are correlated with their three-dimensional molecular structures. Molecular stacking behavior and solid state properties of these "multifunctional" dye materials are presented.The final group of chapters pertains to natural dyes and dyes for natural substrates. In recent years, the impression among certain consumers that "natural" is better/safer has generated much interest in the use of natural dyes rather than synthetics. This has led to a few short discussion papers in which the environmental advantages to using natural dyes have been questioned. The initial chapter in this group provides both a historical look at natural dyes and a comprehensive compilation of natural dye structures and their sources. Though natural dyes are of interest as colorants for textiles, selected ones are used primarily in food and cosmetics.Chapter ten provides an update on the author's previous reviews of structure-color-relationships among precursors employed in the coloration of hair. Chemical constitutions characterizing hair dye structures are presented, along with a summary of available precursors and their environmental properties. Similarly, the chapter on leather dyes covers constitutions and nomenclature, in addition to providing interesting perspectives on the origin and use of leather, the dyeing of leather, and key environmental issues.This volume is concluded with another look at colors in nature. In this case, rather than revisiting colors in plant life, an interesting chapter dealing with color in the absence of colorants is presented. Chapter twelve covers basic concepts of color science and illustrates how 3-D assemblies leading to a plethora of colors are handled in nature. It is our hope that this atypical "color chemistry" chapter will invoke ideas that lead to the design of useful colorants.The chapters presented in this volume demonstrate that color chemistry still has much to offer individuals with inquiring minds who are searching for a career path. This work highlights the creativity of today's color chemists and the wide variety of interesting non-textile areas from which a career can be launched.

Book Description
Experiments in Textile and Fiber Chemistry focuses on selected experiments in the chemistry of fibrous polymers and ancillary materials designed primarily for undergraduate students in technical colleges, polytechnics, and universities. The book first reviews the determination of 'available' chlorine in sodium hypochlorite solution, hardness of water, and estimation of iron in water. The text also ponders on the determination of the saponification and iodine values of oils, use of the pH meter, and use of pH indicators and acid-base titrations. The publication examines the determination of the nitrogen content of organic substances by the Kjeldahl method; separation of amino acids by paper chromatography and paper electrophoresis; and thin layer chromatography. Identification of N-terminal amino acids by the 'Dansyl' method; supercontraction of wool; rendering wool resistant to acid dyeing; effect of breaking disulfide cross-links in wool; and the formation of lanthionine linkages in wool are discussed. The text is a valuable reference for textile and fiber experts interested in the chemistry of fibrous polymers and ancillary materials.

Book Description
The processing of nonwovens depends on a range of technologies, some adapted from the textile and paper industries, others developed uniquely for nonwovens production. The present volume provides a systematic step-by-step explanation of virtually all processes that integrate relevant raw materials into finished nonwovens for different end uses. In comprehensive terms, the book explains the connection between the structure of nonwovens and the specialized, as well as still evolving, technologies used to produce them - from simple roll goods to nanoscale webs and fiberwebs. The unified treatment in the book is meant to serve the needs of engineering and technology students. For students and instructors, the text also offers reviews of basic chemistry, polymer physics and heat transfer concepts, which are linked to processing and design information. Problems and exercises are presented for classroom study and individual practice. The book can also be used profitably as a self-teaching tool by professionals working in or new to the nonwovens industry.From the Foreword by John Hearle In comparison with other publications, the present book covers the great diversity of nonwovens and emphasizes how new types of nonwovens can be created through the use of novel fibres. This approach integrates many aspects of fibres and textile structures that are not associated with the conventional forms of nonwovens, which were established over the last fifty years. In this sense the book summarizes existing technical knowledge and suggests ways of going beyond it.
