Description
The ring-spinning process is an important manufacturing process for the mass customization of clothing goods, especially for large-run yarns. Cop quality is one of the most important characteristics concerning ring-spun yarns. It is mainly evaluated and compared via the diameter of a cop. This study aimed to optimize the ring spinning parameters influencing the cop diameter. The optimization of the spinning process was investigated using the Taguchi method. The diameter of the cop in the ring-spinning process was characterized and evaluated at the variation in spindle speed, traveler mass, and cop height. It was concluded that changing the doff stage over the cop had a severe effect on the diameter of the cop which gave a recommendation for engineering design too but the cop optimum diameter for the manufacturers and researchers. Traveler mass and spinning spindle had no effect. The optimization method of Taguchi gave a reasonable result to the maximum cop diameter corresponding to the specimen and test condition. According to the proposed levels of the control factors it was concluded that the maximum cop dimeter at the bottom ring rail position could be achieved at the factor level K1L1M2. Using the S/N ratio, the best combination of factor levels that yield the highest value of cop diameter was detected efficiently.
