Abstract: The low-stress and recovery properties of ring, rotor and MJS yarns spun from tencel-polyester and tencel-cotton fibre mix have been studied. In comparison with ring and MJS yarns, rotor-spun yarns are more bulky, possess low tensile energy and resilience, lower immediate elastic recovery and have higher delayed elastic recovery and permanent deformation. Ring- spun yarns, on the other hand, possess least decay but behave poorly during abrasion test for 200 cycles. An increase in tencel content in both tencel-polyester and tencel-cotton mixes produces a compact yarn with reduced abrasion resistance, structural integrity and tensile resilience, poor recovery properties, and higher tensile energy. Generally, tencel-polyester yarns display better low-stress characteristics, except the abrasion resistance. Recovery properties have been found to significantly deteriorate with the increase in amplitude of extension regardless of yarn structure.
