dc.description.abstractThe yarn twist of OE rotor-spun yarns has been measured by three different methods, viz. detwist-retwist, twist-to-break and optical. The optical method, based on tracer fibre technique, has been found to be the most reliable and it gives values which are nearer to the mechanical twist. The twist value by this method, called real twist, shows the highest correlation with the nominal twist and correlates well with the values given by the other two methods. Obviously, it shows highest twist values and minimum twist loss. The twist loss increases significantly with the use of grooved nozzle and increase in tex twist factor but decreases with the increase in opening roller speed. Finer yarns exhibit considerably higher real twist loss, whereas increasing rotor speed initially decreases the twist loss followed by an upward trend. The apparent twist losses given by the other two methods depict different trends from real twist loss.en_US
