The course would discuss the molecular architecture, configuration, conformation, amorphous and crystalline phases, glass transition, plasticization, crystallization, melting, factors affecting Tg and Tm of fiber forming polymers.

Essential requirements and examples of fibre forming polymers. Classification of fibres-natural and manmade. Basic structure of a fibre.

General properties of a fibre such as moisture absorption, tenacity, elongation, initial modulus, yield point, toughness, elastic recovery would be discussed.

Production of natural fibres, detailed chemical and physical structure of natural fibres-cotton, wool and silk, their basic properties would be discussed.

Production and structure of important bast and protein fibres would be detailed.Properties of Synthetic fibers and how they differ from their natural counterparts would be explained.
