Tips to fine tune the spinning machinery

Quality breakdown does not mean that the mill is not able to achieve the required average quality parameters. Breakdowns refer to the rejection of lots due to only a few spindles that are producing faulty yarn. To avoid formation of such faulty yarn, it is very necessary that the spindle to spindle variation at ringframes and on winding machines, and machine to machine variation in pre-spinning. This is possible only when the maintenance teams must also act as quality teams and work with statistical quality control (SQC) department to provide the required result.
