Abstract: The properties of tencel-polyester and tencel-cotton blended ring-spun yarns produced with five different blend ratios and six twist factors have been studied. It is observed that tencel-polyester yarns are stronger, more extensible, more even, rigid, less hairy and have fewer imperfections than their tencel-cotton counterparts. A higher level of twist produces a yarn with higher extension, unevenness, imperfection and flexural rigidity, and lower hairiness. The yarn strength, on the other hand, increases initially but decreases thereafter as the yarn twist is further increased beyond that level. An increase in proportion of tencel fibre in the mix enhances the tensile and regularity characteristics of tencel-cotton yarns. However, for tencel-polyester yarns, both these characteristics deteriorate with increase in tencel content in the mix.
