This research is a comparative study of the structural and physical properties of ring, rotor, and friction spun yams and an attempt to explain the differences in their physical properties on the basis of yam structure. Results show that the ring spun yam exhibits the highest fiber migration, followed by rotor spun yam, and friction spun yam with the least, A higher migration factor corresponds with a higher yarn breaking tenacity. An analysis of packing density shows that the fibers for the rotor yam are located most densely near the yam center, while the friction yam has the highest density of fibers near the yam surface. The ring spun yam has a moderately uniform distribution of fiber packing density. The experimental results on fiber arrangement near the yarn axis show that the friction spun yam has the highest rupture elongation due to the skewed arrangement of fibers around the yam axis. Yam hairiness strongly depends on mean fiber position, with an inward shifting of the packing density leading to low yarn hairiness.
