TX4201 Wetting and Wicking of Textile Materials Syllabus:
TX4201 Wetting and Wicking of Textile Materials Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVE
To enable the students to learn about the moisture distribution in textiles during dyeing and printing applications
UNIT I FUNDAMENTALS ON WETTING
Surface tension of liquids and theories on its measurements; equilibrium state of a liquid on a solid; solid-liquid interaction in immersion, penetration, adhesion and spreading
UNIT II CHARACTERIZATION OF WETTING
Determination of wetting force and work of adhesion; measurement of contact angle using Goniometry and tensiometry; critical assessment of the above techniques
UNIT III WETTING OF FIBRES AND FABRICS
Wettability assessment of fibres and filaments using goniometry and tensiometry; importance of wetting of fabrics and its assessment
UNIT IV WICKING IN YARNS AND FABRICS
Fundamentals of wicking; wicking in yarns and its measurement; wicking in fabrics from an infinite and finite reservoirs; studies on factors affecting wetting and wicking in fibres and fibrous assemblies; mathematical models of wetting and wicking
UNIT V APPLICATION
Areas of wetting and wicking of fibrous materials; role of wetting and wicking on comfort behavior of textiles; significance of wetting and wicking in medical and hygiene products; usefulness of wetting and wicking in industrial and domestic products
