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.
Hanbok, Korea’s traditional attire, embodies cultural heritage through intricate designs and craftsmanship. However, preserving its authenticity while meeting modern safety and regulatory standards demands rigorous quality control. As a trusted third-party inspection company, C&Z Quality combines cultural expertise with technical rigor to ensure Hanbok aligns with global benchmarks. Below, we explore common defects, regulatory requirements, and actionable strategies for manufacturers.
Traditional fabrics like silk, ramie, or cotton blends are often mislabeled. For instance, suppliers may substitute high-cost silk with synthetic blends, compromising authenticity. Saekdong (multicolored stripes) or gache (dyed fabrics) using chemical dyes risk non-compliance if restricted substances like azo compounds are present.
Validate fiber content via FTIR spectroscopy and test dyes using HPLC analysis for harmful chemicals.
Hand-stitched seams, especially in jeogori (jackets) and chima (skirts), may exhibit weak tension or uneven stitching. Machine-made imitations often lack durability, leading to frayed hems or detached goreum (ribbons) under stress.
Conduct tensile strength tests (ASTM D5034) on seams and audit workshops for traditional bojagi (wrapping) stitching techniques.
Metal norigae (pendants), embroidered threads, or jokduri (headpiece) components may contain nickel, lead, or choking hazards. A 2024 study found 14% of exported Hanbok failed EU REACH standards due to excessive lead in metallic trims.
Test metal accessories via XRF analysis and enforce ISO 8124-1 standards for small-part safety.
Mandates color fastness (≥ Grade 4) and shrinkage rates for traditional textiles.
Restricts azo dyes, formaldehyde, and heavy metals in fabrics and accessories.
Limits lead content in decorative elements for children’s Hanbok.
A 2024 Incheon Customs report linked 18% of Hanbok rejections to pH imbalances in indigo-dyed chima, underscoring the need for pre-shipment chemical audits.
Partner with certified artisans like Seoul Hanbok Craft Co., which uses natural jujube dyes and hand-embroidered kkoma patterns.
Validate stitching integrity, dye safety (AATCC 61), and metal compliance using ASTM F963 (heavy metal testing) protocols.
Ensure designs adhere to regional styles (e.g., Joseon-era vs. modern fusion Hanbok) to avoid misrepresentation claims.
Deep understanding of binyeo (hairpin) craftsmanship and nubi (quilting) techniques.
Alignment with KC, EU REACH, and US CPSIA standards.
Balancing modern safety protocols with respect for traditional jangni (dyeing) and jogakbo (patchwork) methods.
