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.
Boyshorts, a staple in modern underwear collections, prioritize comfort and versatility. However, their design complexity—from blended fabrics to elastic waistbands—demands rigorous quality control to meet consumer expectations and regulatory standards. As a leading third-party inspection company, C&Z Quality identifies critical compliance gaps and ensures products align with global safety benchmarks. Below, we explore common defects, testing protocols, and actionable strategies for manufacturers.
Blended fabrics like cotton-polyester or nylon-spandex combinations frequently fail composition checks due to mislabeled fiber ratios. For example, DHgate listings highlight cotton-polyester blends but often lack transparency in exact ratios, risking non-compliance with labeling regulations210. Multi-layered designs with lace or seamless finishes are particularly prone to discrepancies if material certifications are not verified.
Use FTIR spectroscopy or XRF testing to validate fiber content and ensure labeling accuracy2.
Loose threads, weak elastic bands, and faulty seams are recurring hazards. Customer reviews on DHgate cite issues like “rough stitching” and “elastic degradation,” leading to discomfort and premature wear411. Front-closure designs with hooks or eyes may also fail stress tests if components lack durability.
Conduct tension tests on waistbands and seams, simulating long-term wear cycles to identify weak points10.
Inaccurate sizing leads to high return rates. DHgate reviews reveal deviations of 2–3 cm in hand-measured dimensions, with customers noting oversized fits for toddlers or mismatched sizing across color variants4.
Standardize sizing charts and audit factories for adherence to ISO 9000 measurement protocols10.
Restricts loose threads and choking hazards in lingerie, including boyshorts10.
Limits phthalates and mandates flammability testing for synthetic fabrics10.
Requires saliva-resistant color fastness (≥ Level 4) for dyed or printed designs10.
A 2024 analysis of EU customs data linked 15% of boyshort rejections to pH imbalances in dyed fabrics, underscoring the need for pre-shipment chemical audits10.
Partner with certified manufacturers like Hanna Import & Export Trade Co., Ltd., which offers customizable adjustments for fabric softness and elastic durability210.
Validate seam integrity, color fastness, and chemical safety using ASTM D5034 (tensile strength) and AATCC 61 (wash durability) protocols10.
Analyze returns data (e.g., DHgate reviews citing “thin fabric” or “transparency issues”) to prioritize high-risk areas like crotch seams or waistbands411.
Advanced evaluations for breathability, moisture-wicking, and pressure distribution, ensuring boyshorts meet ergonomic standards10.
Alignment with EU, US, and Asian regulatory frameworks, including China’s GB 31701 and California Prop 651011.
Predictive analytics to address recurring defects, such as elastic degradation in spandex blends10.
