About GATE Textile Engineering & Fibre Science

Textile engineering is a division of engineering where the principles of scientific techniques are utilized for manufacturing and development in all types of yarns and textile fabric from textile fibers.

Fiber Science investigates the structure, properties and behaviours of fibres and fibrous materials for new industrial materials in particular of nonwoven fabrics and functional materials. … These fibers can be spun into filaments, thread, or rope depending upon the application in the textile industry.
