Abstract: The effects of some jet spinning parameters on the low-stress characteristics of scoured and finished fabrics woven with polyester-cotton jet-spun yarns have been studied. It is observed that the compressional energy, shear energy and coefficient of friction of MVS yarn fabrics decrease initially when the twisting jet pressure is increased from 4 kg/cm2 to 5 kg/cm2 and increase thereafter with the further increase in twisting jet pressure. An increase in nozzle distance on the MVS spinner, on the other hand, causes a significant decrease in these properties. Furthermore, the use of fine yarns decreases compressional energy and coefficient of friction, and the fabrics made from yarn spun with higher jet pressure and wider nozzle distance have higher bending rigidity. The chemical finishing significantly decreases the compressional energy, shear energy, coefficient of friction and bending rigidity.
