Application of six-sigma to reducing end breakage in ring frame spinning

摘要

Six sigma quality improvement process is effective in reducing end breakage rate from 8.89 to 5 per 100SH, resulting in enhanced ring yarn quality, winding efficiency and productivity, with annual savings of Ts 121.8 lacs One basic way to increase profit and quality in the ring-spinning process is to keep the end breakage rate to a minimum level. The end breakage rate is a critical spinning parameter that not only affects the maximum spindle speed but may also indicate the quality of yarn, the mechanical condition of the machine and the quality of raw materials.
