• Physical characteristics textile fibres.
UNIT I | STRUCTURE OF FIBRES | 9 |
---|
Classification of fibres; study of morphological structures of fibers;
physical properties of fibres; order and disorder in fibre structure;
molecular conformations – planar zig-zag, helical, lamellar, and sperulite
conformations
UNIT II | STRUCTURE INVESTIGATION TECHNIQUES | 9 |
---|
Transmission and Scanning electron microscopes - principle; construction
and working; X-ray diffraction techniques – estimation of crystallinity;
Infrared radiation and dichroism techniques; chemical element and group
identification by transmittance and optical density methods, molecular
orientation estimation
UNIT III | MOISTURE ABSORPTION CHARACTERISTICS | 9 |
---|
Theories of moisture sorption; moisture absorption behaviour of natural
and man-made fibres; influence of fibre structure, humidity and
temperature on the moisture absorption; conditioning of fibres – mechanism
of conditioning and factors influencing conditioning. Moisture diffusion
in fibres; heat of sorption – integral and differential, their relation;
factors influencing heat of sorption - measurement of heat of sorption
UNIT IV | MECHANICAL PROPERTIES OF FIBRES | 9 |
---|
Tensile characteristics –study of strength, elongation, work of rupture,
initial modulus, work factor and yield point – determination of yield
point. Stress-strain relations of natural and manmade fibres - influence
of fibre structure, humidity and temperature on tensile characteristics.
Time effect study of creep phenomena. Elastic recovery and its relation to
stress and strain of fibres; mechanical conditioning of fibres and its
influence on elastic recovery. Load cycling and extension cycling-their
effect on elastic recovery. Introduction about torsional and flexural
rigidity of fibers
UNIT V | OPTICAL, FRICTIONAL AND THERMAL CHARACTERISTICS | 9 |
---|
Reflexion and lustre-objective and subjective methods of measurement -
refractive index and its measurement - birefringence, factors influencing
birefringence - absorption and dichroism friction – static, limiting and
kinetic friction, its measurement, comparison of fibres, directional
friction in wool – friction. thermal transitions of fibres - thermal
conductivity, thermal expansion and contraction, Tg and Tm; static
electricity in textile fibres.
