MANUFACTURING AND QUALITY CONTROL BLOG

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.

Comprehensive Quality Inspection Checklist for Drawstring Sweaters: 2025 Industry Standards

C&Z Quality Assurance Protocols for Apparel Excellence

I. Material Integrity Inspection

Fiber Composition Verification

Laboratory burn tests (ISO 1833 standards) to confirm wool/cashmere blend ratios

Nanoparticle analysis for synthetic additives exceeding 5% (e.g., graphene yarns)

Drawstring Durability Testing

500-cycle pull resistance simulation using robotic actuators (EN 14682:2024 update)

II. Structural Compliance Audit

Seamless Knitting Evaluation

3D laser scanning detects >0.5mm stitching irregularities (Shima Seiki benchmark)

Infrared thermal mapping identifies tension variances in underarm zones

Safety Protocol Enforcement

Child safety compliance: Drawstring length ≤7.5cm (CPSC 16 CFR Part 1120)

Magnetic clasp pull force ≤5N to prevent accidental detachment (ISO 8124-1:2025)

III. Performance Validation

Washability Assessment

50-cycle industrial washing (ISO 6330) with 4K microimaging of pilling formation

Colorfastness grading under UV-C light (AATCC 16.3 Class 4+ requirement)

Thermal Regulation Testing

Climate chamber trials (-10°C to 35°C) with thermal camera analysis

Graphene conductivity verification using 4-point probe method (IEC 62631-3-1)

IV. Certifications & Compliance
