Getting the Luster Back

摘要

A textile fiber manufacturing plant was having a production yield problem.On occasion, the plant was producing yarn that was not bright enough. The low-luster yarn was recycled, thus reducing yields and increasing manufacturing costs. When low-luster yarn was produced from a vessel on a 30-vessel machine, that vessel was removed, its screens were cleaned and the vessel was replaced. The plant had been experiencing a higher replacement rate for vessels than it had observed in the past.
