This work covers the chemical, physical and mechanical processes involved in the production of all important commodity manufactured fibres and most of the industrial fibres. The emphasis is on the fundamental principles and industrial aspects of production. Developments in manufactured fibres in terms of manufacturing processes, characteristics and their applications are also included. Areas such as high speed spinning, production of speciality fibres (including microfibres), computer simulation of spinning, high performance fibres, spun-bonding and melt-blowing, and re-use of fibre waste are covered. The structure, property and application areas of each fibre type are discussed. In addition, various aspects related to the testing and characterization of fibres and polymers are reviewed. This book should be of interest to R&D personnel, scientists, technologists and engineers in fibre manufacturing polymer, petrochemical and chemical industries, and to graduates/undergraduates studying textile science, chemical engineering, polymer and fibre science, and materials science.
