A false twist textured yarn is a continuous filament yarn that has been processed to introduce crimps, coils, loops and other fine distortions along the yarn’s length. These distortions give synthetic yarns such as nylon, polyester and polypropylene improved properties such as stretch, bulk, improved thermal insulation and an appearance similar to natural fibres. This important book summarises the key principles, technologies and process issues in the manufacture of high-quality false twist textured yarns. After an introductory chapter on the development of textured yarns, the book reviews yarn texturing machine designs and twist application methods, including air jet mingling and machine variants for draw textured speciality yarns. It also reviews common process performance and quality problems and how they can be resolved, as well process control, quality assurance and costs. The final chapters look at applications of false twist textured nylon, polyester and polypropylene yarns as well as the future of false twist texturing. Based on the author’s extensive experience in the textile industry, False twist textured yarns is a standard reference on the key technologies and process issues involved in the manufacture of high-quality false twist textured yarns. Discusses the development of textured yarns, the basic principles of texturing and the process of false twist texturing Summarises the key principles, technologies and process issues in the manufacture of high-quality false twist textured yarns Chapters include texturing machine design, applications of textured yarns and the future opportunities for false twist texturing

Fancy yarns are those produced with some deliberate discontinuity introduced either into the colour or form of the article with the intention of producing an enhanced aesthetic impression. Most fancy yarns are produced by specialist spinners using machines modified or specially developed for the purpose; others are produced from 'fancy slivers' used as minor components of yarns made by spinners with normal equipment; still others are made exclusively by filament yarns, using adaptations of the airjet texturising process. The text is well illustrated with diagrams, drawings and photographs of yarn structures and the equipment used to create them. It contains close-ups of the yarns themselves together with an analysis to show how appearance and texture can be varied by changing the feedstock or machine settings. Textile historians and conservationists will find the book especially useful in helping to identify yarn types in historical fabrics and in developing an understanding of the variety of yarns available in antiquity and typical uses for them. Fancy yarns is an essential reference to a wide range of industrial textile technologists including spinners, knitters and weavers, fabric and garment manufacturers, students of textile technology and design and curators and conservationists of historical textile collections. The first book to be devoted exclusively to fancy yarns and fancy doubled yarns Describes all the major yarn types, their manufacture and potential for use in garments and furnishing fabrics Includes over 100 drawings, diagrams and photographs

Existing textbooks covering the subject of yarn manufacture largely concentrate on describing the workings of machines. Fundamentals of Spun Yarn Technology presents complete coverage of yarn manufacture and technology and current research findings on the structure and properties of spun yarns. Written by a well-known and respected authority on textile technology, it not only introduces the subject, but it provides students with an advanced understanding of the various process stages. The book introduces the rudiments of staple yarn technology, covering the manufacturing process, the raw materials, and processes including short staple, worsted, semiworsted and woollen spinning, doubling, and specialty yarn processes. It also covers the more advanced studies in staple yarn technology, including new developments in fiber preparation technology, carding technology, roller drafting, gilling, ring spinning, open-end rotor spinning, air jet spinning and new research on unconventional spinning systems. This extensive range of topics, along with hundreds of tables and illustrations presented in Fundamentals of Spun Yarn Technology make it a comprehensive and up-to-date treatment of the field.
