C&Z
QC
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.
Sokoa, the iconic Basque workwear from Spain's Guipúzcoa province, represents centuries of functional design with its reinforced stitching, heavy-duty fabrics, and distinctive blue stripes. As industrial demand grows, counterfeit production has introduced critical safety risks: toxic dyes, structural failures, and performance compromises. At CZ-Quality, we implement specialized protocols to safeguard both worker safety and traditional craftsmanship.
Indigo dyes may contain aniline exceeding EU REACH limits (≤30mg/kg)
Our ICP-OES testing enforces Oeko-Tex Standard 100 compliance, detecting chromium in metal rivets
Formaldehyde in starch stiffeners (tested per UNE-EN ISO 14184-1)
Weak triple-stitching (＜280N) causes seam failure under stress
We perform UNE 40902 tensile tests requiring:
Denim fabric strength ≥400N
Button attachment resistance ≥100N
Reinforced knee panel durability ≥5000 flex cycles
Abrasion resistance (EN ISO 12947-2: ≥20,000 cycles)
Blended cotton replacing pure Basque linen (≥98% natural fibers)
AI pattern validation against San Sebastián Maritime Museum archives
Spectrophotometry ensures traditional "azul naval" stripe (Pantone 19-4034 TCX)
2023 Port of Bilbao Inspection
42% of "authentic" Sokoa overalls violated regulations
31% contained illegal flame retardants (0.18% vs 0.1% limit)
19% showed crotch seam failure after 10 washes
Fabric mill audits for Euskal Label certification
Tension sensors for triple-stitch consistency
ISO 105-E09 resistance to saltwater corrosion
EN 13688 mechanical risk assessment
Partnering with Eibar's master tailors, we deploy 3D fabric scanning for density analysis and blockchain traceability from Basque mills to finished garments. Our 99.4% defect detection ensures compliance with UNE 40900 workwear standards.
