The effect of different process parameters on core-spun yarns made from a modified ring frame has been studied. It is observed that the properties of core-spun yarns vary with respect to the process parameters like type of fibres in core and sheath, different twist levels and different core: sheath ratio. Reduced sheath content in all types of core yarns increases the tensile strength and yarn regularity but decreases the breaking extension and yarn regularity. The optimum twist level for filament and spun core yarns has also been observed. The core-spun yarns have the better physical characteristics than cotton yarns.
