Tester di perdita di liquidi per tessuti non tessuti

**Scope of Application**

Determines the liquid loss performance of nonwoven fabrics. Place a standard absorbent medium beneath the test specimen, position the combined sample on an inclined platform, and measure the liquid penetration through the nonwoven fabric into the absorbent medium when a specific volume of artificial urine flows downward. Calculate the liquid loss performance by weighing the absorbent medium before and after testing.
