Research on Quality Control and Standard Optimization in Jeans Sewing Processes under the Industrial 5.0 Paradigm

Abstract

Abstract

Industry 5.0 advocates a human-centered, intelligent manufacturing paradigm that places heightened demands on garment sewing quality. As a category of apparel ubiquitous worldwide, jeans derive their product competitiveness directly from sewing quality. Drawing on enterprise-based field research, this paper systematically analyzes quality control and standard optimization in the sewing process. The study identifies five categories of sewing defects: fabric surface flaws, seam construction errors, stitching irregularities, component misalignment, and sewing workflow deficiencies. Frequent problems, including soiling, needle holes, slipped stitches, uneven fabric feed, and misaligned cross-seams, stem from multidimensional factors involving equipment, personnel, techniques, and materials. To address these issues, the paper establishes enterprise-level inspection standards comprising 18 key indicators, specifies defect classification criteria, and proposes systematic countermeasures spanning ironing specifications, sewing speed control, and alignment operations. The findings demonstrate that shifting quality control toward in-process management and advancing standards toward greater granularity and quantifiability are critical pathways to improving sewing quality and strengthening corporate competitiveness. This paper provides empirical evidence and practical references for the apparel industry to realize human-centric intelligent manufacturing and sustainable production within the Industry 5.0 framework.
