Colour and appearance perceptions are very complex psychological phenomena. Written by one of the foremost authorities in the field, this major two-volume work addresses the key topics required to understand the issues and manage colour effectively. Principles of colour appearance and measurement Volume 2 addresses the visual measurement of colour, methods of comparing colours, and the management of colour in industry. Volume 2 begins with an overview of the visual measurement of colour. Chapter 1 discusses means of colour communication and various visual attributes of colour. Chapter 2 then focuses on several popular colour order systems, and chapter 3 discusses various colour difference formulae and their use in colour comparison and control. Subsequent chapters review instrumental colorant formulation, metamerism, chromatic adaptation and colour constancy, methods of shade sorting and digital colour reproduction. Addresses the means of colour communication and the various attributes of colour Examines colour order systems and the methods of colour comparison Reviews the management of colour in industry

Advances in technology, combined with the ever-evolving needs of the global market, are having a strong impact on the textile and clothing sector. The global textile and clothing industry: Technological advances and future challenges provides an essential review of these changes, and considers their implications for future strategies concerning production and marketing of textile products. Beginning with a review of trends in the global textile industry, the book goes on to consider the impact of environmental regulation on future textile products and processes. Following this, the importance of innovation-driven textile research and development, and the role of strategic technology roadmapping are highlighted. Both the present structure and future adaptation of higher education courses in textile science are reviewed, before recent advances in textile manufacturing technology, including joining techniques, 3D body scanning and garment design and explored in depth. Finally, The global textile and clothing industry concludes by considering automating textile preforming technology for the mass production of fibre-reinforced polymer (FRP) composites. With its distinguished editor and international team of expert contributors, The global textile and clothing industry: Technological advances and future challenges is an essential guide to key challenges and developments in this industrial sector. Comprehensively examines the implications of technological advancements and the evolving needs of the global market on the textile and clothing industry and considers their role on the future of textile manufacturing The importance of innovation-driven textile research and development and the role of strategic technology roadmapping are thoroughly investigated Recent advances in textile manufacturing technology, including joining techniques, 3D body scanning and garment design and explored in depth

Principles of Textile Finishing presents the latest information on textile finishing for industry professionals and researchers who are new to the field. As these processes are versatile and varied in their applications, the book provides information on how decisions on finishes and techniques may be made subjectively or based on experience. In addition, the book presents the desired final properties of textile materials and how they differ widely from product to product, helping finishers who face significant challenges in delivering fabrics that meet the requirements of end-users be successful. Written by an author who is an expert in the field, and who has with many years of experience in industry and academia, this book provides an accessible introduction to the principles, types, and applications of textile finishes.

Neuronale Netze sind parallele datenverarbeitende Strukturen, die sich selbst verändern können. Mittels dieser Fähigkeit versucht ein Neuronales Netz ein durch Trainingsbeispiele vorgegebenes Ein- und Ausgabeverhalten nachzuahmen und Interpolationseigenschaften zu entwickeln. Fuzzy-Logic ist eine Erweiterung der klassischen Logik in dem Sinne, dass sie statt zwei Werten sämtliche Werte aus aus dem Intervall [0,1] als Wahrheitswerte zulässt. Mit solchen Fuzzy-Werten können vage oder unsichere Daten aus der realen Welt, wie z.B. die linguistischen Terme kurz oder leicht, einfach und zutreffend modelliert werden. Der Autor gibt eine umfassende Einführung in die Theorie und Praxis der natürlichen Informationsverarbeitung, der künstlichen Neuronalen Netze, der Fuzzy-Logic und der genetischen Algorithmen sowie der Kombination der letzten drei genannten Gebiete zu komplexeren Modellen des Soft-Computing . Zudem werden praktische Anwendungen wie die Optimierung von Fuzzy-Controllern mittels Neuronaler Netze beschrieben.

The production of textile materials comprises a very large and complex global industry that utilises a diverse range of fibre types and creates a variety of textile products. As the great majority of such products are coloured, predominantly using aqueous dyeing processes, the coloration of textiles is a large-scale global business in which complex procedures are used to apply different types of dye to the various types of textile material. The development of such dyeing processes is the result of substantial research activity, undertaken over many decades, into the physico-chemical aspects of dye adsorption and the establishment of ‘dyeing theory’, which seeks to describe the mechanism by which dyes interact with textile fibres. Physico-Chemical Aspects of Textile Coloration provides a comprehensive treatment of the physical chemistry involved in the dyeing of the major types of natural, man-made and synthetic fibres with the principal types of dye. The book covers: fundamental aspects of the physical and chemical structure of both fibres and dyes, together with the structure and properties of water, in relation to dyeing; dyeing as an area of study as well as the terminology employed in dyeing technology and science; contemporary views of intermolecular forces and the nature of the interactions that can occur between dyes and fibres at a molecular level; fundamental principles involved in dyeing theory, as represented by the thermodynamics and kinetics of dye sorption; detailed accounts of the mechanism of dyeing that applies to cotton (and other cellulosic fibres), polyester, polyamide, wool, polyacrylonitrile and silk fibres; non-aqueous dyeing, as represented by the use of air, organic solvents and supercritical CO2 fluid as alternatives to water as application medium. The up-to-date text is supported by a large number of tables, figures and illustrations as well as footnotes and widespread use of references to published work. The book is essential reading for students, teachers, researchers and professionals involved in textile coloration.

»Ich bin einer von ungezählten Millionen, die durch Nelson Mandelas Leben inspiriert wurden.« Barack Obama Eine fast drei Jahrzehnte währende Gefängnishaft ließ Nelson Mandela zum Mythos der schwarzen Befreiungsbewegung werden. Kaum ein anderer Politiker unserer Zeit symbolisiert heute in solchem Maße die Friedenshoffnungen der Menschheit und den Gedanken der Aussöhnung aller Rassen wie der ehemalige südafrikanische Präsident und Friedensnobelpreisträger. Auch nach seinem Tod finden seine ungebrochene Charakterstärke und Menschenfreundlichkeit die Bewunderung aller friedenswilligen Menschen auf der Welt. Mandelas Lebensgeschichte ist über die politische Bedeutung hinaus ein spannend zu lesendes, kenntnis- und faktenreiches Dokument menschlicher Entwicklung unter Bedingungen und Fährnissen, vor denen die meisten Menschen innerlich wie äußerlich kapituliert haben dürften.
