Analysis of defects in denim fabric production and investigation of their effects on finished products

The aim of this study is to determine the lower and upper limits of fabric defect scores according to the characteristics of each fabric in denim apparel enterprises with the help of control charts. For this purpose, depending on the fabric type, different denim fabrics were examined with the help of control chart and upper control limits were determined. Another purpose of this study, which examines a 3-year data record, is to examine whether the fabric defect scores have an effect on the finished product. It has been statistically determined that there is no such effect in the light of the data of the enterprise where the application was carried out. Apart from these, a cluster analysis application was carried out in order to provide ease of application in the enterprise and to group fabric types by using the data of the upper control limits of fabric defects.
