Fundamentals of Yarn Winding explains principles related to yarn winding, relevant even to the latest generation of winding systems and useful to textile students as well as to textile professionals in staple and synthetic yarn spinning, weaving, knitting, yarn dyeing, texturising, sewing thread manufacturing, technical textiles, etc. The basics of building winding packages are described in a simplified manner supported by numerous diagrams and photographs. Various terms associated with winding systems/ packages are conceptually clarified, such as random winding, patterning, precision winding, gain, open wind, close wind, step precision winding, etc. Principles of various winding systems along with basic mathematics involved are described.The book discusses various parameters related to build up of winding packages, their influence on package performance and optimization according to end-user requirements. Important elements of winding machines are elaborated such as yarn tensioning and clearing devices, yarn splicers and various methods of package driving and yarn traversing. Current developments in winding machines have opened up immense possibilities in package building that demands thorough understanding of fundamental aspects on the part of the user. It is useful to textile technologists as well as professionals from other disciplines such as chemical, electronics, computer and mechanical dealing with winding systems.
