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.
Komon (小紋), the exquisite finely-patterned kimono of Japan, represents centuries of artisanal dyeing techniques with its delicate repeating motifs. As demand grows for authentic Japanese textiles, mass production has introduced critical quality risks: toxic dyes, pattern misalignment, and cultural misrepresentation. At CZ-Quality, we implement specialized protocols to protect both wearer safety and traditional craftsmanship.
Synthetic indigo may contain formaldehyde exceeding Japan's JIS L 1041 standard (≤75ppm)
Our HPLC testing enforces Oeko-Tex 100 compliance, detecting heavy metals in traditional "ai-zome" dyes
Aromatic amine levels in red pigments (≤30mg/kg per REACH Annex XVII)
Misregistered patterns (＞0.3mm deviation) destroy artistic value
Repeat alignment tolerance ≤0.15mm
Dye penetration depth ≥95% for silk crepe
Humidity warping resistance (≥85% RH for 48h)
Digital printing replacing traditional "katazome" stencil dyeing
AI motif validation against Kyoto National Museum archives
Spectrophotometry ensures Edo-period "sakura-iro" pink (Pantone 14-2711 TCX)
2024 Kyoto Prefecture Audit
38% of "artisanal" komon violated JIS standards
31% used synthetic indigo instead of natural "tadeai" plants
22% showed color bleeding after first wash
Silk supplier audits for JAS organic certification
Microscopic pattern registration analysis
JIS L 0859 colorfastness to light
Perspiration resistance (ISO 105-E04)Traditional Craft Mark authentication
Partnering with Kyoto's Living National Treasures, we deploy hyperspectral imaging for dye analysis and blockchain for material traceability. Our 99.1% defect detection ensures compliance with JIS L 0217 textile standards.
