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.
Children’s underwear requires stringent quality control to meet safety and regulatory standards. As a trusted 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 quality issues, regulatory requirements, and actionable strategies for manufacturers and suppliers.
Color Fastness Failures Color fastness is a recurring problem in children’s apparel, particularly for black, blue, and printed garments. Research shows that dyed fabrics using vulcanized or indigo dyes often exhibit poor friction resistance due to weak dye-fabric bonding. For example, denim clothing has a 69.7% confidence rate for failing wet rubbing tests12. Printed designs, which rely on adhesives, also show compromised rubbing fastness (lift value: 2.77)12.
Prioritize testing for garments containing nylon or acrylic fibers, as their dye-binding mechanisms are inherently weak12.
Blended fabrics (e.g., cotton-spandex) and multi-component textiles (e.g., nylon-viscose blends) frequently fail composition checks. A study revealed that 95% cotton + 5% elastane blends, common in girls’ boxers6, may lack accurate labeling. Garments with three or more fiber types are particularly prone to discrepancies12.
Implement rigorous verification of fiber ratios and labeling, especially for blended materials.
Mechanical hazards, such as loose buttons or choking hazards, are prevalent in underwear and daily tops. Research associates children’s underwear with a 67.39% confidence rate for mechanical safety failures12.
Focus on stress tests for seams, zippers, and embellishments, particularly in high-friction areas.
Prohibits drawstrings in certain areas for children under 14.
Limits phthalates and lead content.
Mandates strict color fastness and mechanical safety checks.
A 2022–2024 analysis of Shanghai Customs data identified five brands with recurring mechanical safety violations and three brands linked to pH imbalances12.
Use association rule mining (e.g., Apriori algorithm) to identify high-risk categories, such as infant pajamas (saliva-resistant color fastness lift: 5.24)12.
Partner with certified manufacturers like Hanna Import & Export Trade Co., Ltd., which offers customizable fabric and design adjustments6.
Verify compliance with ISO 9000 standards, as adopted by factories like MZ Kids Wear & Swimwear15.
Advanced protocols for color fastness, chemical safety, and mechanical durability.
Alignment with EU, US, and Asian regulatory frameworks.
Leverage historical defect data to predict and prevent failures.
