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 machinery
• Covers the patterning of braided products and the structural and colour design of both flat and tubular braids
• Reviews maypole braiding machines and mechanics

This book will be an important resource for students and researchers, technicians, engineers and technologists from the textile and composites industries, and for R&D managers with an interest in the use of braided structures in the medical, aerospace, marine and engineering industries.
