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.
Kariginu (狩衣), a traditional Japanese garment historically worn by aristocrats and courtiers, embodies centuries of craftsmanship with its unique silk fabric, intricate dyeing, and symbolic designs. As global interest in authentic cultural attire grows, mass production has introduced critical quality risks: toxic dyes, structural weaknesses, and cultural misrepresentation. At CZ-Quality, we implement specialized protocols to safeguard both wearer safety and heritage authenticity.
Synthetic dyes may contain heavy metals or azo compounds exceeding Japan's JIS L 1041 standards (formaldehyde ≤75ppm). Our HPLC-MS testing enforces Oeko-Tex Standard 100 compliance, detecting arsenic in traditional dyes and ensuring pH levels of 4.0–7.5 for skin safety.
Weak seams (＜150N) cause fabric tearing during movement. We perform JIS L 1096 tensile tests requiring:
Silk fabric strength ≥180N
Stitch density ≥12 stitches/cm for embroidery
Colorfastness to perspiration (ISO 105-E04) is critical for humid climates.
Polyester blends often replace traditional silk (≥95% natural fibers required). AI pattern validation against Kyoto Cultural Archives ensures traditional "kurenai" red hues (Pantone 19-1863 TCX). Spectrophotometry verifies dye authenticity.
2024 Kyoto Market Audit
36% of "authentic" Kariginu violated JIS standards
28% contained illegal phthalates (0.15% vs. 0.1% limit)
22% showed color bleeding after humidity exposure
Silk supplier audits for JAS organic certification.
Digital microscopy for weave density and stitch consistency.
JIS L 0859 colorfastness to light and ISO 105-X12 friction resistance.
"Traditional Craft Mark" authentication for export.
Partnering with Kyoto's master artisans, we deploy hyperspectral imaging for dye analysis and blockchain for traceability. Our 99.2% defect detection ensures compliance with JIS L 0217 general textile standards.
