Abstract: Stress-strain characteristics of air-jet textured yarn are affected by many factors, including overfeed and constituent feeder yarn properties. After texturing, there is a considerable reduction in tenacity and modulus of yarns. Yarn extension at peak load mostly decreases moderately after texturing. Majority of the textured yarns exhibit catastrophic tensile failure. Core-wetted textured yarns textured with less number of coarse effect filaments exhibit non-catastrophic tensile failure. Normal (parallel-feed) textured yarns are more extensible and have less initial modulus.
