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.
Application
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
Standards
QB/T 2493-2000: Diapers (including diaper care/pads)
FZ/T 60017-1993: Hygienic thin non-woven fabric liquid permeability test method
ISO 9073-6: Nonwovens – Determination of liquid penetration
ASTM F1869/F1869M: Standard test method for liquid penetration resistance of textiles
Product Features
(1) Solenoid-controlled funnel: Simulates liquid application for penetration and strike-through testing
(2) Adjustable mechanical sample holder: Supports multi-test setups with precise angle control for reproducibility
(3) Sensor-integrated control system: Captures real-time liquid penetration data
(4) Data processing software: Transfers test results to a computer, generates curves, and enables in-depth analysis
(5) Automated operation: Simplifies the test process for consistent and accurate results
