Abstract

This work deals with the optimization of consumed thread to seam women’s underwear in the studied design of interest. Indeed, some influential input parameters such as needle and bobbin or looper thread tensioner adjustment, number of layers, fabric thickness, stitch density and sewing thread quality, on the consumption behavior of sewing thread based on knitted fabric to made women’s underwear are investigated and optimized. Based on basic stitch structures to sew female underwire bra and panty, relationships between the consumption behavior of sewing thread and the investigated inputs are derived to decrease the consumption values. Findings show the effectiveness of the metaheuristic techniques to allow industrials to minimize accurately their consumptions of sewing thread to made female underwear. It revealed that women’s underwire bra consumes more sewing threads than panty. Although, the increase of tension of threads to sew female underwear’s decreases the consumed amount of threads, the increase of other studied parameter values widely encourages the consumption values, especially for seams based on chain stitch types. According to the comparative results obtained, this metaheuristic method gives accurate finding values of the consumption within the best combination of input parameters. Therefore, compared to experimental results and regarding the low consumption values obtained, it may be concluded that the both methods give good results except the PSO method is slightly more accurate than the GA method. The PSO method can widely decrease and predict the consumed thread amount, studied inputs and outputs parameters.
