In this study, structural, physical and mechanical properties of cotton-Tencel and cotton-Promodal blended ring, compact and vortex spun yarns were compared. Yarn properties such as hairiness, unevenness, imperfections, diameter, density, roughness, roundness, breaking force and elongation were evaluated. In general, hairiness values of ring yarns are the highest and vortex yarns are the lowest. In regard to unevenness, compact yarns have the best and vortex yarns have the worst values. When the effect of spinning systems is evaluated in terms of breaking force and elongation, results show that compact yarns have the highest values whereas vortex yarns have the lowest. In addition, effects of different blend ratios on a yarn's structural, physical and mechanical properties were examined by using 100% cotton, 100% regenerated cellulosic fibre and 67%-33%, 50%-50%, 33%-67% cotton-regenerated cellulosic fibre blended yarns. In general, an increasing ratio of regenerated cellulosic fibre content in the blend decreases unevenness, imperfections, diameter and roughness values; on the other hand it increases breaking force, elongation, density and shape values. Effect of blend type is also statistically significant for many yarn properties. Mainly, it can be seen that while cotton-Promodal yarns have better physical properties, cotton-Tencel yarns have better mechanical properties.
