Abstract: The effect of process parameters on properties of polyester/viscose blended air-jet textured yarns has been studied. It is observed that with the increase in texturing speed the yarn physical bulk reduces, and instability and tenacity increase. With increasing air pressure or overfeed, the physical bulk and instability increase, whereas tenacity reduces. Regression equations for the prediction of air-jet textured yarns properties have also been derived. On the basis of the regression equations the optimum process parameters for producing good quality air-jet textured yarns have been obtained, considering that the yarns with lowest instability, and high bulk and tenacity are desirable. Yarn instability is accorded the highest weightage while bulk is given intermediate and tenacity the lowest weightage in order to find out the combination of parameters that will produce yarns of low instability, high bulk and high tenacity values.
