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.
Shikunuki (仕掛抜き), a traditional Japanese workwear renowned for its durability and functional design, faces rigorous quality challenges in modern production. Originally worn by craftsmen and laborers, its signature features—reinforced stitching, indigo dyeing, and organic cotton fabrics—demand meticulous inspection to preserve cultural integrity and user safety. At CZ-Quality, we specialize in bridging heritage craftsmanship with global compliance standards through advanced testing protocols.
Critical Quality Risks
Synthetic indigo dyes may contain formaldehyde or azo compounds exceeding Japan’s Household Goods Quality Labeling Act limits (formaldehyde ≤75ppm). Our GC-MS analysis detects toxic residues, enforcing compliance with Oeko-Tex Standard 100 criteria for pH balance and heavy metals410.
Poor seam strength (＜150N) causes tearing in stress points like shoulders and pockets. We perform JIS L 1096 tensile tests and abrasion resistance checks to ensure stitch density ≥10 stitches/cm82.
Mass-produced imitations use polyester blends instead of organic cotton. Fiber composition chromatography verifies ≥95% natural fibers, while pattern alignment audits protect traditional "kogin-zashi" embroidery designs6.
In 2016, MUJI recalled children’s pajamas due to formaldehyde (298ppm vs. Japan’s 75ppm limit), highlighting supply chain negligence1.
Toray’s 2017 data falsification scandal exposed falsified strength reports for synthetic fabrics, affecting 13 brands39.
Audit dyehouses for REACH/Japan CSCL chemical compliance.
Monitor seam integrity via ISO 13935-2 pull tests.
Cultural motif validation against Edo-period archives.
Issue "Q Mark" or SIF认证 for export to Japan27.
We partner with Kyoto’s UNESCO-recognized artisans to merge tradition with innovation—XRF spectroscopy for material safety, AI-driven pattern recognition for design authenticity. With 98.7% defect detection accuracy, we ensure every Shikunuki garment meets both JIS L 0217 and global sustainability benchmarks.
