Diapers are essential products designed to maintain hygiene and comfort, especially for infants. To ensure that diapers meet the required standards for absorption, leakage prevention, and overall performance, manufacturers conduct various testing methods. One critical test for evaluating diaper materials is the liquid strike-through test, which is designed to measure how well a diaper’s outer layer resists liquid penetration. The Liquid Strike-Through Tester GT-CN04 plays a vital role in this testing process, helping manufacturers assess the efficiency and performance of diaper materials in terms of liquid resistance.

• Absorption Capacity: How well the diaper absorbs fluids and prevents them from coming into contact with the skin.
• Leakage Prevention: The ability of the diaper to contain liquid without leakage, which can cause discomfort or irritation.
• Skin Protection: Preventing the skin from becoming irritated due to prolonged exposure to moisture.

• Sample Preparation: A diaper sample (or a nonwoven fabric used in diapers) is placed on a baseplate with absorbent paper underneath. The sample is cut to a standardized size, usually 125mm x 125mm, to ensure consistent testing conditions.
• Solution Setup: A saline solution made from distilled water and salt is prepared. The solution’s surface tension is adjusted to match typical conditions of use, ensuring accuracy in the results.
• Penetration Test: The saline solution is added to the top of the sample using a pipette or suction ball, and the test begins. The GT-CN04 Liquid Strike Through Time Tester measures how long it takes for the liquid to pass through the diaper’s outer layer, simulating real-world wetting conditions.
• Repetition for Consistency: The test can be repeated multiple times to simulate multiple exposures to liquid. This helps manufacturers understand how well the material holds up under continuous use.
• Data Collection and Reporting: After the test, the machine provides detailed results, including the time it took for the liquid to penetrate the material. These results are displayed on a touchscreen interface and can be printed for record-keeping.

• Touch Screen Interface: The machine is controlled via an intuitive color touch screen, which allows users to easily set test parameters and view results.
• Customizable Test Parameters: Users can adjust settings such as penetration time (20-99 seconds) and the number of penetration cycles (1-5 times), tailoring the test to meet specific needs.
• Built-in Printer: The built-in thermal printer enables quick printing of test results, which is useful for documentation and analysis.
• Durable Design: The penetration disc is made of corrosion-resistant material, ensuring long-term reliability. The disc is also equipped with a positioning device to avoid collisions during testing.
• Data Accessibility: All test results and statistical data are easily accessible via the main interface, allowing for quick analysis and reporting.

GB/T 24218 Series: These Chinese standards focus on the testing of nonwoven materials used in diapers, including liquid penetration and absorption performance.
