Abstract: The results of the research work carried out on yarn count variation that could be achieved while using 3/3 drafting system fitted with a short-term, closed loop autoleveller are reported. It has been found possible to spin cotton yarns with a count CV of 1.2-1.4% while using autoleveller. For combed counts, single-passage post-comber leveller drawing appears to be sufficient. Due to the improvement in count CV as a result of the use of autoleveller draw frame, lea count CV improves by 1.2-1.6% and single yarn strength CV by 4%. End breaks in spinning also reduce substantially while using autoleveller draw frame. Of the total yarn count variation, between bobbin variation accounts for 60% and the within bobbin variation for the rest.
