Abstract: The effect of twisting jet pressure, nozzle distance, delivery speed, yarn linear density and fibre composition on the performance and low- stress characteristics of polyester-cotton Murata vortex spun yarns has been studied. The coarser yarns produced using the same conditions exhibit higher abrasion resistance, tensile energy and compressional energy but lower per cent decay. Higher jet pressure and wider nozzle distance offer considerable advantages in respect of structural integrity, abrasion resistance and resilience but there is deterioration in these characteristics at a very high jet pressure. Tensile energy initially increases with the increase in jet pressure and nozzle distance and then drops when jet pressure is further increased. Compressional energy, on the other hand, exhibits a decrease followed by an increase with the increasing jet pressure. Structural integrity and abrasion resistance deteriorate with the increasing delivery speed.
