Available in PDF, EPUB and Kindle. Book excerpt: Properties of spun yarns are mainly affected by fiber properties and yarn structure. Yarn structure is primarily determined by the spinning process. In fact, each spinning process tends to produce a distinctive yarn structure. Recent refinements in spinning technologies have yielded significant improvement in yarn quality; however, the mechanism for these changes is not fully understood. Vortex spinning can be viewed as a modification or refinement of jet spinning, and compact spinning is an enhancement of traditional ring spinning. The present research focuses on identifying those structural differences which can be used to explain the properties of these newer yarns. Prior to the main investigation preliminary trials were conducted to asses the differences between the properties of vortex and air-jet yarns produced from a variety of polyester/ cotton blends. Additionally a literature survey was conducted. A specially designed experimental study was carried out with the role of twist on the properties of compact spun yarn compared to conventional ring spun yarn, and the results clearly show differences in tensile and hairiness characteristics. An attempt is made to explain these differences in terms of structural parameters and in particular faster migration within the yarn. Intuitively one may expect migration to be less for compact yarns because of the more compact yarn formation zone; however, the experimental results clearly show that this is not true and an explanation for the higher migration in compact yarn is proposed. For vortex yarn a similar study is reported, however the differences found for processing conditions are very small and it is difficult to draw any definite conclusion. Possible reasons for this are given. A new approach to yarn structure analysis and quantification is also investigated and shown to offer great potential as a tool for this type of study.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Smart-textiles developers draw on diverse fields of knowledge to produce unique materials with enhanced properties and vast potential. Several disciplines outside the traditional textile area are involved in the construction of these smart textiles, and each individual field has its own language, specific terms and approaches. Multidisciplinary know-how for smart-textiles developers provides a filtered knowledge of these areas of expertise, explaining key expressions and demonstrating their relevance to the smart-textiles field.Following an introduction to the new enabling technologies, commercialisation and market trends that make up the future of smart-textiles development, part one reviews materials employed in the production of smart textiles. Types and processing of electro-conductive and semiconducting materials, optical fibres for smart photonic textiles, conductive nanofibres and nanocoatings, polymer-based resistive sensors, and soft capacitance fibres for touch-sensitive smart textiles are all discussed. Part two then investigates such technologies as the embedding of electronic functions, the integration of thin-film electronics, and the development of organic and large-area electronic (OLAE) technologies for smart textiles. Joining technologies are also discussed, alongside kinetic, thermoelectric and solar energy harvesting technologies, and signal processing technologies for activity-aware smart textiles. Finally, product development and applications are the focus of part three, which investigates strategies for technology management, innovation and improved sustainability, before the book concludes by exploring medical, automotive and architectural applications of smart textiles.With its distinguished editor and international team of expert contributors, Multidisciplinary know-how for smart-textiles developers is a key tool for readers working in industries including design, fashion, textiles, through to electronics, computing and material science. It also provides a useful guide to the subject for academics working across a wide range of fields. - Reviews materials used in the production of smart textiles - Examines the technologies used in smart textiles, such as optical fibres and polymer based resistive sensors - Investigates strategies for technology management, innovation and improved development

Available in PDF, EPUB and Kindle. Book excerpt: Studying the yarn formation with the swirling air concept arouse of interest of the researchers for a long time because it appears to be easy to understand as a spinning principle. These kinds of systems are known as the vortex yarn spinning systems. The air-jet spinning methods have been developed since it is possible to eliminate the movable elements as the spindle and the traveler in ring spinning or the centrifuge in rotor spinning. The success of Murata vortex spinning (MVS) system which is the newest system after all studies of air-jet systems has been much acceptable especially for the spinning ability of 100% cotton in high speeds (500 m/min) and the yarn structure resembling ring yarn structure rather than rotor yarns. This study summarizes the historical background of vortex spinning, the spinning principle and the structure of the yarn spun on this system, as well as the factors influencing the yarn quality and finally the developments in vortex spinning technology.
