CHARACTERISTICS OF TEXTILE FIBRES

 LTPC

3003

COURSE OBJECTIVES:
• To enable the students to understand the  Physical characteristics of textile fibres

UNIT I

STRUCTURE AND INVESTIGATION TECHNIQUES OF FIBRES

9

Classification of fibres; study of morphological structures of fibers; Transmission and Scanning electron microscopes-principle; construction and working; X-ray diffraction techniques – estimation of crystallinity; Infrared radiation and dichroism techniques

UNIT II

MOISTURE ABSORPTION CHARACTERISTICS

9

Theories of moisture sorption; moisture absorption behavior 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 – factors influencing heat of sorption - measurement of heat of sorption


UNIT III

TENSILE AND ELONGATION CHARACTERISTICS 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 effects- study of creep phenomena

UNIT IV

ELASTIC RECOVERY BEHAVIOUR OF FIBRES

9

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 - friction – its measurement, comparison of fibres, directional friction in wool – friction. thermal transitions of fibres - thermal conductivity, thermal expansion and contraction, Tg, melting; static electricity in textile fibres

TOTAL: 45 PERIODS

COURSE OUTCOMES: Upon completion of the course, students will be able to
CO1 Investigate and identify fibers based on their morphological structure.
CO2 Identify the factors influencing moisture and heat sorption behavior of fibres.
CO3 Identify the factors influencing tensile and elongation behavior of fibres.
CO4 Understand the elastic recovery behaviour of fibres.
CO5 Understand and measure the optical, frictional, and thermal characteristics of fibres
