I. Product Overview
The MMT Liquid Water Separation Tester is a precision instrument designed to evaluate the water repellency and separation efficiency of textile materials, coatings, and membranes. It quantifies liquid absorption resistance and hydrophobic performance using standardized spray and drainage methods, critical for waterproof fabric development and quality assurance.

- Test Standards: AATCC 22 (Spray Rating), ISO 4920 (Water resistance)
- Key Metrics:
- Water Repellency Rating (0–5 scale)
- Separation Efficiency (%)
- Absorption Time (seconds)
- Sample Size: 150×150mm (adjustable clamping)
