Textured Yarn Technology

By Prof. Kushal Sen   |   IIT Delhi
This course would cover the fundamentals of twist texturing of fully drawn yarns. Theneed and the solutions that emerged because of material challenges and machinelimitations leading to the evolution of draw-texturing and friction texturing. Emergence ofAir - jet texturing, interlacement and bulked continuous yarns is also covered. Hi-bulkyarns principles and production of the same. Also covered would be the interestingpossibilities of using solvents and chemicals to produce textured yarns
