Abstract: The effects of scouring treatments on the structural and recovery characteristics of cotton ring- and rotor-spun yarns have been studied. In general, ring yarns have high mean fibre extent, spinning-in coefficient, immediate elastic recovery and delayed recovery, and less permanent set than the rotor-spun yarns. The results show that the scouring produces high immediate elastic recovery and delayed recovery but reduces permanent set, irrespective of the yarn structure. Although a greater effect is obtained with caustic scouring than with enzyme scouring, the magnitude depends mainly on processing factors. The structural properties reasonably reduces for different types of scouring treatments.
