Abstract: The response of polyester/viscose MJS yarns to annealing under relaxed condition has been studied. It is observed that the annealing significantly increases the breaking extension and abrasion resistance but adversely affects the tenacity and initial modulus of yarn . The flexural rigidity of yarn considerably decreases whereas the elastic recovery increases on annealing. The variation in properties on annealing is more conspicuous in the yarns produced with higher proportion of polyester fibre and lower first jet pressure.
