Waste factor evaluation using theoretical and experimental jean pants consumptions

Abstract

This paper focuses on a contribution of modeling consumption of sewing thread during clothing jeans classic pants. In fact, to determine accurately the amount of sewed thread used by assembly type needs to model widely the amount of thread in each stitch type taking into consideration the waste factor contributions. Several factors determine the extent of thread consumption in any sewn garment, such as seam length, stitch density, seam types, and material thickness. Nevertheless, the variability of factors depends on the different styles of garment that let thread consumption of sewn product categories such as jean pants, shirts, and jacket to be variable. However, these factors are not constant with the different styles of garment. Hence, thread consumption is never a standard for sewn product categories such as trousers, jackets, shirts, products lingerie, and footwear. Regarding the linear regression method results, it may be concluded that waste factor is correlated accurately with the experimental sewing thread consumption. Our findings show that developed theoretical consumption equations give more accurate values compared to experimental ones. Likewise, taking account of waste factor in our theoretical analysis helps to obtain objectively the real sewing thread consumption value.
