Abstract: The behaviour of rotor-spun doubled yarns differs from that of ring-spun doubled yarns. A D/S twist ratio of 0.8 yields consistently the best double yarn quality index for S over Z ply cotton yarns. Loose wrapper coils get disturbed and disintegrated by the action of doubling traveller. Rotor-spun ply yarns have higher snarling twist than their ring-spun counter-parts.
