Abstract: The influence of first nozzle pressure, gauge length, main draft and condenser width on the initial modulus and flexural rigidity of polyester and viscose yarns has been studied using the Box-Behnken experimental design. The interaction effect among the process variables has been analyzed. It is observed that the initial modulus and flexural rigidity of jet-spun yarn increase with the increase in first nozzle pressure, gauge length and condenser width individually when the other variables are set at lower levels. However, the above yarn characteristics may decrease with the change of one variable at a time keeping the other variables at higher levels. The changes in yarn flexural rigidity with the process variables can be predicted from the yarn initial modulus.
