Yarn Preparation

Almost all fabrics, whether woven or knitted, are produced from spun thread. However, this thread or yarn, produced by the spinning operation, either by a hand spinner using the simplest drop spindle or spinning wheel, or spun on the latest automated spinning frame, is rarely in a form suitable to be used immediately for producing a fabric. A broad range of tasks must be undertaken before the actual fabric production is reached. "Yarn Preparation" is concerned with the preparation of yarns which have been spun from staple fibres, and describes the post-spinning processes prior to fabric manufacture, such as yarn doubling, winding and spinning. Covers the operations to consider when producing a fabric by even the most basic of techniques. The information on basic processes, machinery and equipment should assist those people involved in the production of fabrics by showing ways to improve the quality to the end product. Includes a list of suppliers, sources of further information and a reading list. This is a valuable book which fills the need for a practical manual specifically about yarn preparation. Much has been published about the main textile areas of yarn manufacture and fabric production (both weaving and knitting), because yarn preparation tends to be a series of link operations, there have been very few books specifically directed to this area of processing. The "Small-Scale Textiles" series aims to present basic information about all aspects of small-scale textile manufacture from raw rmaterials to finished products, and will be of use to fieldworkers, development agencies, and those starting small-scale manufacture or attempting to improve or extend manufacture.

The book has been prepared considering the dire need of the students. It is indeed intriguing to note that no text books are available, that cover the entire sequence of processes in the area of weaving preparation. Students therefore had to refer to a number of books. The unique feature of the book is that it meets the syllabi requirements of the universities/polytechnics. The book is divided into four divisions, namely, winding, warping, sizing, and drawing. A special chapter has been devoted to the preparatory aspects of micro denier yarns. Also the latest BTRA norms are included. This makes the book very valuable to students. The topic on winding covers all the basic aspects of the winding process, technological developments, winding aspects of sewing threads, and winding of packages for dyeing. The section in warping discusses about the types of warping, productivity, quality related aspects and modern developments. The section on sizing deals with the basic process, principle, chemistry, developments and quality control. The readers will find the book to be very useful for teaching as well as learning.

Introduces the processes of spinning and dying yarn and explains how to match homespun fiber and yarn to knitted projects.

Dealing with the classical processes for textile dyeing, as well as with the preparation of the material before dyeing, this book also includes recent technological developments. Both theoretical and the practical aspects are covered in order to enable the students and the technicians to understand the processes clearly.

For spinners and weavers alike! Get in-depth information on fiber properties and color choices, as well as beautifully photographed samples. Spin to Weave is not simply a how-to-spin book, but a how-to-spin-exactly-what-you-want book. Weavers who spin their own yarns have the ability to choose fiber type, method of twist insertion (woolen, worsted), twist amount and/or direction, finishing methods, and grist. Author Sara Lamb focuses on the process of spinning for specific results, providing detailed instructions, a sampling of projects, variations, and a gallery of pieces by other spinners. Sara takes the reader to the very source of woven fabric--introducing the thought processes and concepts related to choosing fibers and how to spin them with finished fabric in mind.

Written by one of the world's leading experts, Handbook of yarn production: technology, science and economics is an authoritative and comprehensive guide to textile yarn manufacturing. The book is designed to allow readers to explore the subject in various levels of detail. The first three chapters provide an overview of yarn production, products and key principles. The major part of the book then reviews in detail the production processes for short-staple, long-staple and filament yarns.There are also chapters on quality control and the economics of staple-yarn production. The final part of the book consists of a series of appendices which provide in-depth analysis of key topics with detailed technical data and worked examples which is an invaluable reference in itself for anyone concerned with the behaviour, performance and economics of a textile mill. Handbook of yarn production: technology, science and economics is a standard work for both yarn manufacturers and those researching and studying in this important area of the textile industry. A practical and authoritative new handbook for yarn manufacturing Shows how problems can arise and how to deal with them Includes invaluable technical data, calculations, worked examples and case studies
