In period underwear manufacturing, quality control determines product performance, leak protection, absorbency reliability, and customer trust. Unlike regular underwear, period underwear contains multiple functional layers, so even a small defect can affect user experience.
Therefore, professional OEM period underwear factories use strict quality control systems to ensure every product meets safety, comfort, and performance standards.
1. Raw Material Inspection
Material quality is the foundation of reliable period underwear production. Before manufacturing begins, factories inspect fabrics, absorbent layers, and waterproof barriers.
Key Checks Include:
- Fabric composition and GSM testing
- Absorbent core performance
- Elastic durability
- Safety certifications such as OEKO-TEX®
- Waterproof layer quality
Furthermore, high-quality materials improve comfort, absorbency, and product durability.
2. Pattern and Cutting Accuracy Control
Even excellent materials cannot perform well without accurate cutting and assembly. Period underwear requires precise alignment between the absorbent core, gusset area, and waterproof barrier.
- Pattern grading accuracy
- Gusset coverage inspection
- Panel symmetry checking
- Layer positioning control
As a result, accurate cutting helps prevent edge leakage and improves wearing comfort.
3. Gusset Assembly and Leakproof Testing
The gusset is the most important functional area of period underwear because it controls absorption and leakage prevention.
Professional factories check:
- TPU/PUL waterproof barrier placement
- Lamination strength
- Seam quality
- Stitch consistency
Moreover, many leakage problems come from structural issues rather than absorbent material failure. Therefore, leakproof inspection is essential before production.
4. Absorbency Performance Testing
Absorbency must be measured through professional testing instead of relying only on product claims.
Common Testing Methods:
- Liquid absorption capacity testing
- Pressure simulation testing
- Re-wet testing
- Leak distribution evaluation
For example, simulation tests help factories understand how products perform during daily activities such as walking and sitting.
5. Wash Durability and Final AQL Inspection
Since period underwear is reusable, durability testing is an important quality checkpoint.
Factories test:
- Absorbency after washing
- Elastic recovery
- Waterproof layer durability
- Fabric condition
Additionally, final AQL inspection helps control defects before shipment and ensures consistent production quality.
