Liquid slip penetration comprehensive performance tester
Category：Other
Introduction
The Liquid Slip Penetration Comprehensive Performance Tester is designed for evaluating the liquid permeability and absorption characteristics of hygiene-grade thin nonwoven fabrics. It is widely used for testing materials used in feminine sanitary pads, diapers, medical protective materials, and other absorbent hygiene products.
By delivering controlled volumes of artificial urine onto the nonwoven sample and detecting penetration time via electrical sensors, the instrument ensures precise, repeatable, and reliable measurements for product quality assessment and R&D.
Application Fields
Sanitary napkin surface materials
Baby diaper top sheets and wrapping materials
Medical absorbent pads
Hygiene-grade thin nonwoven fabrics
R&D and quality control in hygiene product manufacturing
Material performance evaluation in testing laboratories
Working Principle
A measured amount of artificial urine is released onto a nonwoven fabric sample positioned over a standard absorbent pad. The instrument uses a platinum-coated electrode detection system to monitor the exact moment the test liquid completely penetrates through the sample.
The time from initial liquid release to full penetration is recorded automatically, providing an objective measure of liquid permeability performance.

FAQ
1. What materials can this tester evaluate?
It is suitable for hygiene-grade thin nonwoven fabrics including sanitary pad topsheets, diaper surface materials, medical absorbent materials, and various lightweight hydrophilic fabrics.
2. What type of test liquid is used?
The instrument uses artificial urine formulated according to standard requirements to simulate real-world liquid behavior in hygiene products.
3. How is penetration time measured?
Platinum-coated electrode sensors detect when liquid fully passes through the sample. The system automatically records and displays the total penetration time.
4. Can the flow rate and liquid volume be adjusted?
Yes. The automated dispensing system allows precise adjustment of flow rate (50–200 mm/min) and dispensing volume, ensuring accurate testing for different fabric types.
5. What industries commonly use this equipment?
Manufacturers of sanitary napkins, diapers, medical nonwovens, and third-party laboratories rely on this tester for product development, quality assurance, and compliance testing.
