This book contains detailed knowledge about testing principles of fibre, yarn, and fabric characteristics, the tensile characteristics of materials and testing of fibrous-composites and technical textiles. It starts with an introduction to textile testing and further covers moisture in relation to textile materials, sampling techniques for textile materials and the basic applied statistics, fibre characteristics, fibre length, cotton fibre fineness and maturity characteristics. It also deals with the advanced characterisation of cotton fibre by using HVI and AFIS systems. Features: It covers the principles of the testing of textile and fibrous materials along with modern techniques for testing textile materials It reviews all necessary topics related to fibre, yarn, fabric, technical textiles, and composite testing It explores the tensile characteristics of textile materials and measurement principles It discusses low-stress mechanical characteristics and transmission characteristics It includes a large number of examples and exercises based on actual industrial conditions worldwide including solutions This textbook is aimed at senior undergraduate students in textile testing and evaluation of textile materials.
This book provides an invaluable single source of information on the advances in yarn spinning technologies. Advanced spinning systems are described and comparisons are made of the properties of the yarns produced, and resultant finished products, with those from conventional systems.Part one provides an introduction to yarn fibre spinning and structure. Chapters discuss the principles of ring spinning and open-end spinning of yarns. Yarn structure and properties from different spinning techniques and yarn structural requirements for knitted and woven fabrics are also examined. Part two covers advances in particular yarn spinning technologies. Topics range from siro spinning to compact spinning technology and air-jet spinning. Final chapters explore how to minimise fibre damage which occur during spinning and the use of spin finishes for textiles.With its distinguished editor and array of international contributors, Advances in yarn spinning technology is an important text for spinners, yarn manufacturers and fabric producers, as well as researchers, technicians, engineers and technologists in this sector of the textile industry. - Documents advances in spinning technologies and presents comparisons between systems - Assesses particular textile spinning technologies with specific chapters focusing on siro, compact, rotor, friction and air-jet spinning - Reviews measures to minimise fibre damage caused by spinning are investigated with specific relevance to rotor and friction spinning
Gorgeous knitting patterns designed by the Green Mountain Spinnery of Putney, Vermont. In their vintage mill in rural Vermont the artisans at Green Mountain Spinnery create 99 richly colored natural-fiber yarns. In this follow-up to their popular Green Mountain Spinnery Knitting Book, they offer 36 classic and modern, stylish and fun patterns. There’s a flock of sweaters, as well as shawls, shells, and vests; an array of socks, mittens, and hats; even an afghan. Patterns range from easy to challenging; whatever your knitting skills, you’ll find projects to please. Detailed pattern charts and schematics round out this must-have volume. The Spinnery also recounts how they became a worker-owned cooperative and takes readers on a fascinating photographic tour of their mill. Unlike most commercial yarns, Spinnery yarns are untouched by bleach or chemicals. Enhanced by gorgeous photographs throughout, this book will be an inspiration and a jumping-off point for your own creative adventures in knitting.
