Braiding Technology for Textiles: Principles, Design and Processes

Braided fabrics are made by interlacing yarns or strips of fabric. Braiding produces a wide range of structures for technical textile applications from medical sutures to cables for anchoring ships. Written by one of the world's leading experts in the field, the book reviews the basic principles, design and processes used in braiding. The book also discusses specialised braiding techniques such as spiral braiding and lace technology. Provides a solid foundation in the fundamentals of braiding design, processes and machineryCovers the patterning of braided products and the structural and colour design of both flat and tubular braidsReviews maypole braiding machines and mechanics INDICE: Woodhead Publishing Series in Textiles Preface Dedication Acknowledgements 1.
