Research on Optimizing Sewing Processes for the Welt Pocket and Zipper of Jackets

Abstract

This study uses the MTM time measurement method and the GSD predetermined time system to conduct the construction of the machining time norms for the welt pocket and zipper of jackets. The use of automatic welting machine has significantly saved (35.4%) total operations and 31.06% total assembly time. The programming machine that is used saves most of the time in

processing the welt pockets and zipper up to 24.5%, especially integrating 2 stages of sewing the welt pocket and zipper in the same process with the machine. It saved 30% times of operations. Initial research results have provided data as the basis for solutions to increase labor productivity and quality of jacket production.
