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.
Wireless bras have surged in popularity for their comfort and versatility, but their design complexity demands rigorous quality control to meet consumer expectations and regulatory standards. As a leading third-party inspection company, C&Z Quality specializes in identifying critical compliance gaps and ensuring products align with global safety benchmarks. Below, we explore common defects, testing protocols, and actionable strategies for manufacturers.
Blended fabrics, such as cotton-polyester or nylon-spandex combinations, often fail composition checks due to inaccurate labeling. For example, M&S’s minimiser bras list 86% polyamide and 14% elastane, but deviations in ratios can lead to durability issues like stretched bands or reduced elasticity9. Similarly, DHgate listings highlight cotton-polyester blends but lack transparency in fiber ratios, risking non-compliance with labeling regulations4.
Conduct fiber content verification using advanced testing methods like FTIR spectroscopy to ensure labeling accuracy.
Loose straps, faulty closures, and protruding underwires are recurring hazards. M&S customer reviews reveal complaints about underwires piercing through fabric, causing discomfort and safety risks9. Front-closure designs (common in DHgate listings) may also fail stress tests if hooks or eyes lack durability4.
Implement tension tests for straps and closures, particularly for front-fastening bras, to simulate long-term wear.
Inaccurate sizing leads to high return rates. DHgate suppliers note hand-measured dimensions may deviate by 2–3 cm, while M&S customers report inconsistent fits across color variants49.
Standardize sizing charts and audit factories for adherence to ISO 9000 measurement protocols.
Restricts loose threads and choking hazards in lingerie.
Limits phthalates and mandates flammability testing for padded bras.
Requires color fastness (saliva resistance ≥ Level 4) for infant apparel, extending to bras with printed designs49.
A 2024 analysis of EU customs data linked 12% of wireless bra rejections to pH imbalances in dyed fabrics, highlighting the need for chemical safety audits.
Supplier Collaboration: Partner with certified manufacturers like Hanna Import & Export Trade Co., Ltd., which offers customizable adjustments for fabric softness and strap strength4.
Validate seam integrity, color fastness, and mechanical safety using ASTM D5034 (tensile strength) and AATCC 61 (wash durability) protocols.
Analyze returns data (e.g., M&S reviews citing “rough stitching”) to prioritize high-risk areas like underband seams9.
Advanced evaluations for breathability, moisture-wicking, and pressure distribution.
Alignment with EU, US, and Asian regulatory frameworks.
Leverage defect analytics to predict failure points, such as elastic degradation in blended fabrics.
