Thecontinuing advances in the field of sports, protective textiles, medical andhygiene requirements, etc, existing fibers is being modified and new fibers arebeing developed to meet specific and stringent requirements of the technicalapplications. There is a regular demand for the production of functional andspecialty fibres. Therefore the fiber and polymer technologists have beencontinuously innovating new fibres to develop high performance and functionaltextiles. The term high functional fibers can interpreted in a number ofdifferent ways. One interpretation is that, it is a fibre with high tenacity,high modulus and less weight for the application of filtration and sportstextiles. In the case of medical and hygiene products, it should free from toxicand biodegradable. For protective textiles, fibers should be high resistance tocorrosive chemicals and high resistance to elevated temperatures, flames andvery high hydrophilic. In the next millennium, textiles will not just be anextension on simple alternatives to natural or synthetic fibres, they willprovide superior functionalities and enter into more novel and unexpectedapplications. New millennium fibres describe and identify the scope of high -tech fibres. The present status and prospects of the fibre are discussed andthe high performance fibres are reviewed from origin to future applications. Toread more,
