Summary

Polyester and polyamides remain the most used group of synthetic fibres. This authoritative book reviews their methods of production, ways of improving their functionality and their wide range of applications.The first part of the book describes raw materials and manufacturing processes, including environmental issues. Part two considers ways of improving the functionality of polyester and polyamide fibres, including blending, weaving, coloration and other finishing techniques as well as new techniques such as nanotechnology. The final part of the book reviews the range of uses of these important fibres, from apparel and sportswear to automotive, medical and civil engineering applications.With its distinguished editors and international team of contributors, Polyester and polyamides will be a standard reference for all those using this important group of fibres.
