Statistical Quality Control of Cotton-Polyester Blended Spun Yarns Using Control Charts


Abstract in English

Control charts have been applied in this research, as a measure of Statistical Quality Control (SQC), to control the quality of cotton-polyester blended yarns produced at Al-Wleed Spinning Company. This method is not currently applied at the company, and it is used in this research to check whether or not the production process is statistically in control, and whether or not the variations in quality characteristics are random and cannot be controlled or assignable and can be dealt with.
