The defects which are occurred at the production process in the apparel factory, affect quality of the product and productivity of the factory and also they increase the cost of production. For quality improvement and decreasing the cost of production, it is necessary to avoid poor quality. In this research, it is examined to decrease the sewing defects by using statistical process control (SPC) methods in the apparel factory.
The research is studied in a middle sized apparel factory in Izmir. The SPC methods such as check list, pareto analysis, cause-effect diagram and P control chart are used. The frequencies of sewing defects in the operations at the sewing department are determined by check list. The operations which have highest sewing defect rates and the effects of these operations to the defect rate, are examined by using the pareto analysis. The reasons of the defects are analyzed with the cause-effect diagram for the operation which has the highest sewing defect rate. The rate of defect in the sewing department is examined statistically by p control chart whether it’s under control or not.
It is proved that the apparel factories can decrease the sewing defects by using the statistical process control methods. Although a lot of people think that the statistic and SPC methods are hard to use, they are not difficult and the middle sized apparel factories can easily use these methods.
