Abstract: 
It’s been a problem over the years that auto cone produces more imperfection and co-efficient of variation (CV) percentage than ring yarn. It was found that lowering the gauge from the running setting results for better quality yarn (less CV% and imperfection) without affecting any other parameters related with production. Thus, it can clearly be stated that less yarn clearer gauge results for better quality yarn.
