Performance Evaluation of Disposable Diapers

Performance Evaluation of Disposable Diapers

Background

A supplier of consumer goods was preparing a new disposable diaper for market launch and sought independent verification of its key functional performance. As consumer expectations for hygiene products continue to rise, diaper performance is increasingly evaluated not only by basic absorbency, but also by factors such as liquid intake, dryness, liquid retention, and overall wearing comfort. These properties are closely related to the diaper's absorbent structure and material configuration and can directly influence product quality and consumer acceptance.

Before finalizing the product specifications and quality requirements, the client needed reliable performance data to assess whether the diaper could effectively absorb, retain, and manage liquid under simulated use conditions. The evaluation was also intended to provide an objective basis for confirming the effectiveness of the product design and identifying potential areas for performance optimization. Independent third-party testing was therefore required to generate impartial and reproducible results.

Our Solution (Testing Scope & Methodology)

Our laboratory conducted a comprehensive performance evaluation of the diaper samples using internationally recognized test methods. Each test parameter was performed on multiple specimens to ensure data repeatability and provide statistically representative performance results. (Sample numbers selected according to the requirements of each evaluation method.)

The evaluation covered critical parameters related to liquid management and material comfort, including:

Analytical Results & Findings

The testing results provided a comprehensive understanding of the diaper's absorption and comfort-related performance.

Key findings include:

• The diaper exhibited a high liquid absorption capacity, demonstrating the effectiveness of its absorbent core in managing large fluid volumes.
• Consistent acquisition performance indicated efficient liquid transport from the surface into the absorbent structure.
• Low rewet values confirmed that the absorbent system effectively minimized liquid returning to the surface after pressure application, helping maintain a drier contact layer.
• The absorbent core maintained a high level of retained liquid following the standardized extraction procedure, supporting reliable leakage control during use.
• Air permeability testing characterized the breathability of the diaper materials, providing additional information for balancing wearer comfort with liquid containment.

Value Delivered to the Client

Through independent laboratory verification, the client obtained reliable performance data to support product optimization, quality control, and market readiness. The testing results helped validate the diaper's absorption efficiency, liquid retention capability, and comfort-related characteristics, providing technical evidence for product development decisions and customer communication.
