Reduction Of Color Variation Defects In Polyester Dyeing Process

Abstract
This research presents a methodology to reduce color variation defects in the polyester dyeing process. Color variation is the most prevalent defect found in the case study. Failure Mode and Effect Analysis (FMEA) and Fishbone diagram are used to analyze root causes and prioritize the causes. The pretreatment process and the dyeing laboratory are the early steps of dyeing process. The improvement in these stages has significant effects on reducing process variation which leads to color variation defects. The result shows that the percentage of color variation defects is reduced from 20.61% to 17.32%.
