Structure And Mechanics Of Textile Fibre Assemblies

Structure and Mechanics of Textile Fibre Assemblies, Second Edition, offers detailed information on all aspects of textile structure and mechanics. This new edition is updated to include the latest technology and techniques, as well as fiber assembly for major application areas. Chapters discuss the mechanics of materials and key mechanical concepts, such as stress, strain, bending and shear, but also examine structure and mechanics in-depth, including fabric type, covering yarns, woven fabrics, knitted fabrics, nonwovens, tufted fabrics, textile composites, laminated and coated textile fabrics, and braided structures. Finally, structure and mechanics are approached from the viewpoint of key applications areas. This book will be an essential source of information for scientists, technologists, engineers, designers, manufacturers and R&D managers in the textile industry, as well as academics and researchers in textiles and fiber science. Provides methodical coverage of all essential fabric types, including yarns, woven fabrics, knitted fabrics, nonwovens, tufted fabrics, textile composites, laminated and coated textile fabrics, and braided structures Enables the reader to understand the mechanical properties and structural parameters of fabric at a highly detailed level Expanded update includes an analysis of fiber assemblies for key technical areas, such as protective fabrics and medical textiles

Textile structure and mechanics are fundamental to the way textiles are designed, manufactured, tested and used. Structure and mechanics of textile fibre assemblies discusses aspects of fabric structure and mechanical properties such as tensile, bending and shear properties for a range of fabrics. After a general introduction illustrating the role of fabric structure and mechanics, subsequent chapters discuss the structural, tensile, bending and shear properties of woven, knitted and nonwoven fabrics. Other chapters review the structure and mechanics of yarns, coated fabrics, 2D and 3D textile composites. Testing methods for the measurement of fabric mechanical properties and structure parameters are also explored. With its renowned editor and contributions from some of the world’s leading authorities, Structure and mechanics of textile fibre assemblies is an important reference for textile scientists, technologists, engineers and those designing and manufacturing textiles. It will also be suitable for those within the academic sector. Examines aspects of fabric structure and mechanical properties for a range of fabrics Discusses structure and mechanics of yarn and woven, nonwoven and knitted fabrics Explores testing methods enabling the measurement of fabric mechanical properties and structural parameters

Continued and systematic analysis of the mechanics of flexible fibre assemblies dates from about 1945, although the growth of research into textiles after 1920 had included studies of fabric structure and the measurement of mechanical properties. The subject is thus a young one, although this NATO Advanced Study Institute is a sign of developing maturity. However there is an earlier tradition. Relevant, even if somewhat loosely connected, quotations can be found in the works of the engineers of the ancient civilisations, recurring during the llenaissance with Leonardo da Vinci and Galileo. But the glorious libk is with Euler and the Bernoulli family, with their theories of the mechanics of flexible slender rods. While mathematicians have admired the beauty of this work, the invention of elliptic integrals, and the grace of the different classes of planar elastica, it is in the technology of textile materials, composed of flexible fibres and yarns, that the subject has found its more direct application. All this, and much more such as Max Born's doctoral thesis, was brought to our attention in a delightful discourse by Milos Konopasek, who is not only fascinated by the mathematics of Euler and the modern movement of the solutions of bending curves from two dimensions into three by the use of the computer, but also feels a personal link through having lived and studied within sight of the scene of Euler's triumphs in St. Petersburg.

Fabric mechanics are fundamental to the way textiles are designed, tested and manufactured and underpin the way woven fabrics are used in the modern world. With fully comprehensive coverage of all aspects of fabric anisotropy, stress-strain relationships and fabric drape modelling and testing, structure and mechanics of woven fabrics, discusses and exemplifies all major aspects of fabric mechanics and their relevance to every stage of the contemporary textile industry. ?? After a general introduction illustrating the role and study of woven fabric mechanics, the first group of chapters examines the structural, tensile, bending and shear properties of woven fabrics. Sections cover the general behaviour of these properties, how they are modelled and their anisotropy. Drape deformation modelling is covered extensively, one chapter detailing theory and a second, computation and simulation. The properties of fabrics with seams and fabric complex deformation analysis and simulation are also detailed. ?? Structure and mechanics of woven fabrics is an essential reference for all textile academics, students, researchers, technicians, engineers and technologists, covering all areas of textile material applications, from composites and geotextiles, to medical textiles and biotextiles.

This book represents a system of theoretically-derived inherent laws of a special type of fibrous assembly, known as yarn. Structural approach has been the basis of this book. Each chapter of this book is started with definitions, terminologies and fundamental relations. Then the theoretical models are presented namely from the initial assumptions through the mathematical derivation to the final relations. Such theoretical results are mostly compared with the experimental results.The topics on yarns include count, twist and diameter, number of fibres in cross-section, retraction and saturated twist, fibre helix, fibre migration, mass unevenness, hairiness, strength, fibre slippage, etc.

Examining the structure and mechanics of materials, this book represents a system of theoretically derived inherent laws of fibrous assemblies and looks specifically at yarns, particularly from a structural point of view.
