In the garment industry, whether you are a manufacturer, importer, or brand, you must understand the importance of quality control in this business. This industry shifts swiftly, and any time lost in shipment or defect fixings can lead to unimaginable losses. Moreover, quality issues can quickly disseminate in the digital age, giving competitors an advantage. Therefore, quality control is essential, and quality inspection is the most commonly used method. In this post, we will guide you through the steps of a garment quality inspection, the key checkpoints to focus on, and how can C&Z expertise support your garment quality control.
The Jeogori, the iconic upper garment of the Korean Hanbok, embodies centuries of tradition through its elegant lines, vibrant colors, and intricate embroidery. However, preserving its cultural essence while meeting modern safety and regulatory standards demands rigorous quality control. As a trusted third-party inspection company, C&Z Quality ensures every Jeogori aligns with global benchmarks. Below, we explore common defects, regulatory requirements, and actionable strategies.
Traditional fabrics like silk or ramie may be substituted with synthetic blends. Suppliers might use polyester disguised as myeonbok (ceremonial silk), violating Korea’s KC Certification for textile authenticity.
Validate fiber content via FTIR spectroscopy and audit suppliers for OEKO-TEX® certification.
Hand-embroidered ggeutdong (decorative cuffs) or machine-stitched git (ribbon trim) may loosen under stress. A 2024 study found 18% of Jeogori failed due to detached saekdong (multicolored stripes).
Conduct tensile strength tests (ASTM D5034) on seams and verify thread purity via XRF analysis.
Vivid dancheong (traditional pigments) or metal norigae (pendants) may contain cadmium or lead. EU REACH reports indicate 15% of exported Jeogori exceeded phthalate limits in 2024.
Test dyes via HPLC and enforce EN 71-3 standards for child-safe accessories.
Mandates color fastness (≥ Grade 4) and fabric shrinkage rates.
Restricts azo dyes, formaldehyde, and heavy metals.
Certifies chemical content analysis for textiles.
A 2024 Seoul Customs report linked 20% of Jeogori rejections to pH imbalances in indigo-dyed collars, underscoring pre-shipment audits.
Partner with certified hanbok ateliers like Seoul Heritage Crafts, using organic dyes and traditional jogakbo (patchwork) techniques.
Validate embroidery adhesion (ASTM D903), dye safety (AATCC 61), and goreum (ribbon tie) durability.
Ensure designs adhere to historical styles (e.g., Joseon-era vs. modern minimalist Jeogori).
Mastery of kkekki (pleating) and nubi (quilting) techniques.
Alignment with KC, EU REACH, and ISO 9001 standards.
Balancing advanced testing with respect for hanji (traditional paper) lining traditions.
