WASTE REDUCTION OF DYEING AND FINISHING PROCESS BY SIX SIGMA

Abstract

The objective of this research was to reduce the proportion of chemical reprocesses through dyeing and finishing in the sample plant; DMAIC methods were used and applied using the Six Sigma techniques to improve the production process. The analysis had found that the waste from the production process does not meet the standards of quality assurance. In the chemical reprocess of the dyeing and finishing, the main problems are failures with colorfastness related to washing, chemical stains and dye stains. Failure modes & effect analysis (FMEA) was used to identify the most prominent causes after analyzing the actual sources and by implementing engineering techniques (IE-Technique), the problems could be solved.

 The result show that number of reprocess was to reduce the waste of colorfastness to washing from 75,919.35 to 31,071.71 yard or 59.07 percent. Chemical stains from 52,941.38 to 45,042.30 yard or 14.92 percent. Dye stains from 126,075.55 to 87,681.12 yard or 30.45 percent.
