Full Unit-wise Syllabus
Unit I – Introduction and Cultivation of Natural Fibres
Definition of staple fibre, filament; classification of fibres; essential and desirable properties of fibres; fibre forming polymers and its properties; morphological structure of cotton and wool; Cultivation and extraction of natural fibers – cotton, jute, flax; sericulture of silk; extraction of wool fibre; chemical composition; structure and properties of fibres.
Activity: List out the properties of various natural fibres.
Unit II – Manmade Fibres
Production sequence of regenerated and modified cellulosic fibres – viscose rayon, acetate rayon, high wet modulus and high tenacity fibres; synthetic fibres – polyester, nylon, polypropylene, polyethylene, acrylic and polyurethane; chemical structure and properties; production principles.
Activity: Identify the natural and manmade fibres with the given materials.
Unit III – Moisture Absorption Behaviour of Natural and Man-made Fibres
Conditioning of fibres – mechanism of conditioning and factors influencing conditioning, moisture diffusion in fibres; tensile characteristics; elastic recovery and mechanical conditioning of fibres; Tg and Tm; static electricity in textile fibres; friction and its measurement for fibres.
Activity: Virtual demonstration of measuring the various properties.
Unit IV – Characterization of Fibres
Identification of fibres; transmission and scanning electron microscopes – principle and working; X-ray diffraction techniques – estimation of crystallinity; infrared radiation and dichroism techniques.
Activity: Demonstration of various characterization instruments for the fibres.
