Applications:

The tester is widely used in:

(1) Diaper and hygiene product manufacturing for evaluating absorbency, strike-through, and backflow resistance

(2) Non-woven fabric R&D for assessing liquid penetration properties of sanitary materials

(3) Quality control laboratories for verifying batch-to-batch performance of diapers and pads

(4) Third-party testing institutions for product performance certification

(5) Regulatory and supervisory agencies for monitoring compliance with hygiene and safety standards

Product Information:

The G373 Liquid Sliding Penetration Comprehensive Performance Tester is a precision instrument designed to evaluate the liquid penetration performance of diapers and hygienic non-woven fabrics. It accurately measures strike-through, back-seepage, and overall penetration efficiency, simulating real-world liquid exposure to assess product quality and reproducibility. The tester integrates a solenoid-controlled funnel, adjustable sample holder, and automated data acquisition for precise and repeatable results.

Test Procedures

(1) Place the diaper or non-woven sample on the sample holder and adjust to the specified angle

(2) Fill the funnel with the test liquid and set the solenoid valve for controlled flow

(3) Start the test: the liquid penetrates the sample, and sensors capture real-time data

(4) Apply the pressing block for 1 minute if required to simulate pressure

(5) Record strike-through, back-seepage, and penetration data; analyze via software

(6) After testing, clean the funnel, sample holder, and pressing block to avoid residue buildup

(7) Periodically calibrate the flow rate, angle, and sensor system to ensure consistent and accurate results
